This is a best efforts public offering of up to 13,003,901 shares of our common stock, par value $0.001 per share, together with (i) Series A warrants to purchase up to an aggregate of 13,003,901 shares of our common stock (the “Series A Warrants”), (ii) Series B warrants to purchase up to an aggregate of 13,003,901 shares of our common stock (the “Series B Warrants”) and (iii) Series C warrants to purchase up to an aggregate of 13,003,901 shares of our common stock (the “Series C Warrants” and collectively, with the Series A Warrants and the Series B Warrants, the “Common Warrants”) at an assumed combined public offering price of $0.769 per share and one Series A Warrant, one Series B Warrant and one Series C Warrant (the last reported sale price per share of our common stock on the Nasdaq Capital Market on February 11, 2025). We are also offering pre-funded warrants to purchase up to 13,003,901 shares of our common stock (the “Pre-Funded Warrants”) and the shares of common stock issuable upon exercise of the Pre-Funded Warrants, in lieu of shares of common stock, to those investors whose purchase of shares of our common stock in this offering would result in the investor, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the investor, 9.99%) of our outstanding common stock immediately following the consummation of this offering. Each Pre-Funded Warrant will be exercisable for one share of our common stock. Each Pre-Funded Warrant is being sold together with one Series A Warrant, one Series B Warrant and one Series C Warrant. Each Pre-Funded Warrant and the accompanying Common Warrants will be offered at an offering price equal to the combined public offering price at which a share of common stock and accompanying Common Warrant is being offered, minus $0.001. The exercise price of the Pre-Funded Warrants will be $0.001 per share, and the Pre-Funded Warrants will be immediately exercisable and may be exercised at any time until exercised in full. For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. The number of Common Warrants sold in this offering will not change as a result of a change in the mix of the shares of our common stock and Pre-Funded Warrants sold. The exercise price of the Common Warrants will be $ per share. The Common Warrants will be exercisable immediately on the effective date of stockholder approval of the issuance of the shares upon exercise of the Common Warrants (the “Warrant Stockholder Approval Date” and such approval, the “Warrant Stockholder Approval”); provided, however, that, if and only if the Pricing Conditions (as defined below) are met, the Common Warrants will be exercisable upon issuance. As used herein “Pricing Conditions” means that the combined offering price per share and accompanying Common Warrants is such that the Warrant Stockholder Approval is not required under the rules of the Nasdaq Stock Market LLC because either (i) the offering is an at-the-market offering under the rules of the Nasdaq Stock Market LLC and such price equals or exceeds the sum of (a) the applicable “Minimum Price” per share under Nasdaq Rule 5635(d) plus (b) $0.125 per whole share of common stock underlying the Common Warrants or (ii) the offering is a discounted offering where the pricing and discount (including attributing a value of $0.125 per whole share underlying the Common Warrants) meet the pricing requirements under the Nasdaq Stock Market LLC’s rules. The Series A Warrants will expire five years from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series A Warrants will expire five years from the date of issuance. The Series B Warrants will expire twenty-four months from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series B Warrants will expire twenty-four months from the date of issuance. The Series C Warrants will expire nine months from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series C Warrants will expire nine months from the date of issuance. This offering also relates to the shares of common stock issuable upon the exercise of any Pre-Funded Warrants and any Common Warrants. The shares of common stock and Pre-Funded Warrants, as the case may be, and the accompanying Common Warrants, can only be purchased together in this offering but will be issued separately and will be immediately separable upon issuance.

Our common stock is currently listed on the Nasdaq Capital Market under the symbol “BPTH.” On February 11, 2025, the last reported sales price per share of our common stock on the Nasdaq Capital Market was $0.769. All share, Pre-Funded Warrant and Common Warrant numbers are based on an assumed combined public offering price of $0.769 per share and accompanying Common Warrants (or $0.768 per Pre-Funded Warrant

and accompanying Common Warrants). The actual public offering price per share of common stock and accompanying Common Warrants and per Pre-Funded Warrant and accompanying Common Warrants, as the case may be, will be determined between us, the Placement Agent (as defined below) and the investors at the time of pricing, may be at a discount to the current market price, and may be based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this offering. Therefore, the assumed combined public offering price used throughout this prospectus may not be indicative of the final offering price. There is no established public trading market for the Pre-Funded Warrants or the Common Warrants, and we do not expect a market to develop. In addition, we do not intend to list the Pre-Funded Warrants or the Common Warrants on the Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system.

This offering will terminate on , 2025, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all securities purchased in this offering and the combined public offering price per share of common stock (or Pre-Funded Warrant) and accompanying Common Warrants will be fixed for the duration of this offering.

We have engaged as our exclusive placement agent (the “Placement Agent”) to use its reasonable best efforts to solicit offers to purchase our securities in this offering. The Placement Agent has no obligation to purchase any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. Because there is no minimum offering amount required as a condition to closing in this offering the actual public offering amount, Placement Agent’s fee, and proceeds to us, if any, are not presently determinable and may be substantially less than the total maximum offering amounts set forth above and throughout this prospectus. We have agreed to pay the Placement Agent the Placement Agent fees set forth in the table above. See “Plan of Distribution” in this prospectus for more information. There is no arrangement for funds to be received in escrow, trust or similar arrangement. Because there is no escrow account and no minimum offering amount required as a condition to closing this offering, we may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue our business goals described in this prospectus. We will bear all costs associated with the offering.

Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described in the section titled “Risk Factors” on page 11 of this prospectus.

Our Company

We are a clinical and preclinical stage oncology and obesity-focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target-specific protein inhibition for any gene product that is over-expressed in disease. Our drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a lipid bilayer having neutral charge. We believe this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. Through testing in numerous animal studies and dosing in clinical trials, our DNAbilize® drug candidates have demonstrated an excellent safety profile. DNAbilize® is a registered trademark of the Company.

Using DNAbilize® as a platform for drug development and manufacturing, we currently have four drug candidates in development to treat at least five different cancer disease indications. Our lead drug candidate, BP1001, or “prexigebersen” (pronounced prex” i je ber’ sen), which is being developed to target growth factor receptor-bound protein 2 (“Grb2”), initially started the efficacy portion of a Phase 2 clinical trial for untreated acute myeloid leukemia (“AML”) patients in combination with low-dose cytarabine (“LDAC”). However, the changing landscape of AML treatment has led to amendment of the Phase 2 clinical study by removing the combination treatment of prexigebersen and LDAC and replacing it with the combination treatment of prexigebersen and decitabine.

In October 2020, the U.S. Food and Drug Administration (“FDA”) granted approval of venetoclax in combination with LDAC, decitabine or azacytidine (the latter two drugs are DNA hypomethylating agents) as frontline therapy for newly diagnosed AML in adults who are 75 years or older, or who have comorbidities precluding intensive induction chemotherapy. We believe this approval of the frontline venetoclax and decitabine combination therapy provides an opportunity for developing prexigebersen as an addition to the combination therapy for the treatment of newly diagnosed AML patients. In preclinical efficacy studies, four AML cancer cell lines were treated with three different combinations of decitabine, venetoclax and prexigebersen. Decrease in AML cell viability was the primary measure of efficacy. The triple combination of decitabine, venetoclax and prexigebersen showed significant improvement in efficacy in three of the four AML cell lines. Based on these results, we believe that adding prexigebersen to the treatment combination of decitabine and venetoclax could lead to improved efficacy in AML patients.

Our approved amended Phase 2 clinical trial currently has three cohorts of subjects. The first two cohorts will treat patients with the triple combination of prexigebersen, decitabine and venetoclax. The first cohort will include newly diagnosed AML patients, and the second cohort will include relapsed/refractory AML patients. Finally, the third cohort will treat relapsed/refractory AML patients, who are venetoclax-resistant or -intolerant, with the two-drug combination of prexigebersen and decitabine. The full trial design plans have approximately 98 evaluable patients for the first cohort having newly diagnosed AML patients with a preliminary review performed after 19 evaluable patients and a formal interim analysis after 38 evaluable patients. The full trial design plans have approximately 54 evaluable patients for each of the second cohort, having relapsed/refractory AML patients, and the third cohort, having AML patients who are venetoclax-resistant or -intolerant, in each case with a review performed after 19 evaluable patients. The study is anticipated to be conducted at up to ten clinical sites in the U.S., and Gail J. Roboz, MD, is the national

coordinating Principal Investigator for the Phase 2 trial. Dr. Roboz is a professor of medicine and director of the Clinical and Translational Leukemia Program at the Weill Medical College of Cornell University (the “Weill Medical College”) and the New York-Presbyterian Hospital in New York City.

The safety run-in of the triple combination of prexigebersen, decitabine and venetoclax for the Phase 2 clinical study was successfully completed. The preliminary data, presented at the 2021 ASH Annual Meeting, showed the treatment was well-tolerated and there were no dose limiting toxicities attributed to prexigebersen.

On June 3, 2024, we announced additional interim data for the first two cohorts of the Phase 2 clinical trial. In Cohort 1, 31 newly diagnosed patients were enrolled; 20 evaluable patients with a median age of 75 years, treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk or secondary AML evolved from myelodysplastic syndromes, chronic myelomonocytic leukemia or treatment-related AML. Fifteen patients (75%) achieved complete remission (“CR”), CR with partial recovery of peripheral blood counts (“CRh”), or CR with incomplete hematologic recovery (“CRi”). One patient achieved partial remission (“PR”), three patients achieved stable disease, and one patient had toxicity attributed to decitabine and venetoclax treatment. In Cohort 2, 40 relapsed/refractory patients were enrolled; 23 evaluable patients with a median age of 63 years, treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk or secondary AML. Twelve patients (55%) achieved CR/CRi/CRh, one patient achieved PR, eight patients achieved stable disease and two patients had progressive disease or treatment failure. Among the evaluable patients of both cohorts, adverse events were consistent with those expected with decitabine and venetoclax and/or AML, including fatigue (72%), anemia (60%) and neutropenia (49%), while the most frequent severe adverse events were febrile neutropenia (26%) and sepsis (5%). The interim analysis data was selected as an oral presentation in the 2024 American Society of Clinical Oncology (“ASCO”) Annual Meeting and as a poster presentation in the 2024 European Hematology Association (“EHA”) Annual Meeting. Based on this interim data, we expect to continue enrollment of up to 98 and 54 evaluable patients for Cohorts 1 and 2, respectively and plan to pursue FDA expedited programs for Fast Track designation. We are evaluating whether to seek to expand Stage 2 of the Phase 2 clinical trial in Europe. We expect to complete enrollment in cohorts 1 and 2 in 2026.

Our second drug candidate, Liposomal Bcl-2 (“BP1002”), targets the protein Bcl-2, which is responsible for driving cell survival in up to 60% of all cancers. A Phase 1 clinical trial to evaluate the ability of BP1002 to treat refractory/relapsed lymphoma and refractory/relapsed chronic lymphocytic leukemia (“CLL”) patients is being conducted at the Georgia Cancer Center, The University of Texas Southwestern and New York Medical College. A total of six evaluable patients are scheduled to be treated over two dose levels with BP1002 monotherapy in a standard 3+3 design. Enrollment has been successfully completed for both dose cohorts, 20 and 40 mg/m2. There were no dose limiting toxicities.

On December 11, 2024, we announced that the Phase 1 clinical trial evaluating BP1002 as a treatment for refractory/relapsed lymphoma and refractory/relapsed chronic lymphocytic leukemia has discontinued enrollment. This decision was based on enrollment challenges in these niche indications, particularly given the crowded development landscape that includes multiple competing trials.

Additionally, preclinical studies suggest that the combination of BP1002 with decitabine is efficacious in venetoclax-resistant cells. An abstract of the preclinical study was presented at the 2021 American Association for Cancer Research (“AACR”) Annual Meeting. A Phase 1/1b clinical trial to investigate the ability of BP1002 to treat refractory/relapsed AML patients, including venetoclax-resistant patients, is being studied. A recent study found that AML patients who had relapsed from frontline venetoclax-based treatment had a very poor prognosis, with a median survival of less than three months. Since venetoclax and BP1002 utilize different mechanisms of action, we believe that BP1002 may be a potential treatment for venetoclax-relapsed AML patients. The Phase 1/1b clinical trial is being conducted at several leading cancer centers in the United States, including the Weill Medical College, The University of Texas MD Anderson Cancer Center (“MD Anderson”), Scripps Health and The University of California at Los Angeles Cancer Center. On October 7, 2024, we announced that the FDA had completed its review of PK/PD data from the first two dosing cohorts (20 and 40 mg/m2) and that the enrollment for the third dosing cohort (60 mg/ m2) is now complete. We expect to enroll the next planned higher dose of 90 mg/m2 in the first quarter of 2025. The approved treatment cycle is two doses per week over four weeks, resulting in eight doses administered over twenty-eight days. The Phase 1b portion of the study is expected to commence after

TABLE OF CONTENTS

completion of BP1002 monotherapy cohorts and will assess the safety and efficacy of BP1002 in combination with decitabine in refractory/relapsed AML patients.

Our third drug candidate, Liposomal STAT3 (“BP1003”), targets the STAT3 protein and is currently in IND enabling studies as a potential treatment of pancreatic cancer, non-small cell lung cancer (“NSCLC”) and AML. Preclinical studies showing BP1003’s ability to inhibit STAT3 protein expression and cancer cell viability had been presented at AACR Annual Meetings. On September 16, 2024, we announced a publication in the peer-reviewed journal, Biomedicines, which highlights the therapeutic potential and broad anti-tumor effect of BP1003 in numerous preclinical solid tumor models, including breast, ovarian, and pancreatic cancer. The lead indication for which we intend to develop BP1003 is pancreatic cancer due to the severity of this disease and the lack of effective, life-extending treatments. For example, pancreatic adenocarcinoma is projected to be the second most lethal cancer behind lung cancer by 2030. Typical survival for a metastatic pancreatic cancer patient is about three to six months from diagnosis. We have successfully completed several IND enabling studies of BP1003 and have one additional IND enabling study to complete. Once the additional study is successfully completed, our goal is to file an IND application and initiate the first-in-humans Phase 1 study of BP1003 in patients with refractory, metastatic solid tumors, including pancreatic cancer and NSCLC.

In addition, a modified product named BP1001-A, our fourth drug candidate, has shown to enhance chemotherapy efficacy in a preclinical study involving solid tumor models. Results of the preclinical study were published in the scientific journal Oncotarget in July 2020. BP1001-A incorporates the same drug substance as prexigebersen but has a slightly modified formulation designed to enhance nanoparticle properties. A BP1001-A Phase 1/1b clinical trial in patients with advanced or recurrent solid tumors is being conducted at several leading cancer centers in the United States, including MD Anderson, Karmanos Cancer Institute, Mary Crowley Cancer Research and Holy Cross Hospital, Maryland. On July 17, 2023, we announced completion of the first cohort of the dose escalation portion of the Phase 1/1b clinical trial. A total of nine evaluable patients are scheduled to be treated with BP1001-A monotherapy over three dose levels in a standard 3+3 dose escalation design. The first dose cohort consisted of a starting dose of 60 mg/m2, and there were no dose limiting toxicities. Enrollment is now open for patients for the second dose cohort of 90 mg/m2 which we expect to be complete in the first quarter of 2025 in order to advance to dose level 3. The Phase 1b portion of the study is expected to commence after successful completion of BP1001-A monotherapy cohorts and is intended to assess the safety and efficacy of BP1001-A in combination with paclitaxel in patients with recurrent ovarian or endometrial tumors. Phase 1b studies are also expected to be opened in combination with gemcitabine in Stage 4 pancreatic cancer and combination therapy in breast cancer.

Development and Treatment for Obesity

Insulin resistance is a major contributor to obesity, Type 2 diabetes and other related metabolic diseases. Insulin lowers blood glucose level by activating the phosphoinositol-3 kinase (PI3K)/AKT pathway. However, this insulin pathway is dysfunctional in obese patients who have Type 2 diabetes. Literature suggests that Grb2 is an inhibitor of the insulin/PI3K/AKT pathway. Upregulation of the Grb2 gene has been reported for patients with Type 2 diabetes. Knockdown of Grb2 expression enhanced insulin-induced AKT activity and glucose uptake in myoblast and hepatoma cells. Furthermore, insulin sensitivity was restored in Grb2 heterozygous knockout mice fed on high fat-induced diet. We are currently exploring the development of BP1001-A as a drug candidate to target insulin resistance. We hypothesize that by downregulating Grb2 expression, BP1001-A could potentially lower blood glucose level by enhancing insulin-mediated AKT activation and glucose uptake and storage and are pursuing studies to test such hypothesis.

On December 19, 2024, we announced the results of our initial preclinical work; BP1001-A, by downregulating Grb2 expression, increased the levels of phosphorylated AKT and phosphorylated FOXO-1 (a downstream AKT effector) in myoblast and hepatoma cells in the presence of insulin. These preliminary data confirmed that BP1001-A could affect the insulin/PI3K/AKT pathway and increase insulin sensitivity, thus validating BP1001-A as a potential candidate to target obesity in Type 2 diabetes patients. We have initiated animal studies to evaluate the efficacy of BP1001-A as a potential treatment for obesity and related metabolic diseases in Type 2 diabetes patients. If successful, we intend to initiate a first-in-human Phase 1 clinical trial in 2025 to further validate safety, measure pharmacokinetics and establish dosing for potential pivotal trials.

TABLE OF CONTENTS

Our DNAbilize® technology-based products are available for out-licensing or partnering. We intend to apply our drug technology template to new disease-causing protein targets to develop new liposomal antisense drug candidates for inclusion in our pipeline that meet scientific, preclinical and commercial criteria and file new patents on these targets. We expect that these efforts will include collaboration with key scientific opinion leaders in the field of study and include developing drug candidates for diseases other than cancer. As we expand our drug development programs, we will look at indications where a systemic delivery is needed and antisense RNAi nanoparticles can be used to slow, reverse or cure a disease, either alone or in combination with another drug.

We are developing a molecular biomarker package to accompany prexigebersen treatment, the goal of which is to identify patients with a genetic profile more likely to respond to the investigational treatment and improve the probability of success for this program as a result. The emerging role of biomarkers has been enhancing cancer development over the past decade and has become a more common companion to many cancer development programs. We expect to develop molecular biomarker packages to accompany our new programs.

We have certain intellectual property as the basis for our current drug products in clinical development, prexigebersen, BP1002, BP1003 and BP1001-A. We are developing RNAi antisense nanoparticle drug candidates based on our own patented technology to treat cancer and autoimmune disorders where targeting a single protein may be advantageous and result in reduced patient adverse effects as compared to small molecule inhibitors with off-target and non-specific effects. We have composition of matter and method of use intellectual property for the design and manufacture of antisense RNAi nanoparticle drug products.

Recent Developments

Warrant Exercises

During the period beginning October 1, 2024 and ending on the date of this prospectus, investors have exercised certain of our outstanding pre-funded warrants to purchase 2,057,702 shares of our common stock (such exercises, the “Warrant Exercises”).

October 2024 Private Placement

Nasdaq Minimum Bid Price Compliance

As previously reported, on December 12, 2024, we received a letter (the “Bid Price Letter”) from the Listing Qualifications Department of the Nasdaq Stock Market (“Nasdaq”) indicating that, based upon the closing bid price of our common stock for the last 30 consecutive business days, we did not meet the minimum bid price of $1.00 per share required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Rule”). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have been provided an initial period of 180 calendar days, or until June 10, 2025, to regain compliance with the Minimum Bid Price Rule. The Bid Price Letter also indicated that if at any time

TABLE OF CONTENTS

before June 10, 2025 the closing bid price for our common stock is at least $1.00 for a minimum of ten consecutive business days, Nasdaq will provide us with written notification that we comply with the Minimum Bid Price Rule.

If we do not regain compliance with the Minimum Bid Price Rule by June 10, 2025, we may be eligible for a second compliance period of 180 calendar days, provided that we meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Price Rule, and we notify Nasdaq of our intention to cure the deficiency during such second compliance period, including by effecting a reverse stock split, if necessary.

If we do not regain compliance with the Minimum Bid Price Rule by June 10, 2025 and we are not eligible for a second compliance period at that time, Nasdaq will provide us with written notification that our common stock may be delisted. At that time, we may appeal Nasdaq’s delisting determination to a Nasdaq Hearings Panel (the “Panel”). If we timely appeal, we would remain listed pending the Panel’s decision. There can be no assurance that, if we do appeal the delisting determination by Nasdaq to the Panel, such appeal would be successful.

We intend to continue to monitor the closing bid price of our common stock and may, if appropriate, consider implementing available options to regain compliance with the Minimum Bid Price Rule, including by effecting a reverse stock split. As previously reported, at the Company’s Annual Meeting of Stockholders on December 12, 2024 (the “Annual Meeting”), our stockholders approved an amendment to our Certificate of Incorporation to effect a reverse stock split of our common stock at a ratio of up to 1-for-30, to be determined by our board of directors, within twelve months from the date of the Annual Meeting, subject to the authority of our board of directors to abandon such reverse stock split.

Nasdaq Stockholders’ Equity Requirement Compliance

As previously reported, on November 19, 2024, we received a letter (the “Stockholders’ Equity Letter”) from the Panel granting our request for continued listing on the Nasdaq Capital Market in connection with our appeal of the delisting determination to the Panel, subject to certain conditions that must be complied with by January 31, 2025. On January 30, 2025, we filed an extension request with the Panel requesting an extension of the January 31, 2025 deadline to February 19, 2025. We must (i) demonstrate compliance with the minimum stockholders’ equity requirement of at least $2,500,000 pursuant to Nasdaq Listing Rule 5550(b)(1) (the “Stockholders’ Equity Requirement”), (ii) publicly disclose compliance with the Stockholder’s Equity Requirement in accordance with the terms of the Stockholders’ Equity Letter and (iii) provide the Panel with income projections for the next twelve months and evidence compliance with all applicable criteria for continued listing on the Nasdaq Capital Market. If we do not satisfy these requirements, we may be subject to delisting. The Panel reserves the right to reconsider the terms of the extension based on any event, condition or circumstance that exists or develops that would, in the opinion of the Panel, make continued listing inadvisable or unwarranted.

As previously reported, on March 12, 2024, we received a deficiency letter from the Listing Qualifications Department of Nasdaq notifying us that we are not in compliance with the Stockholders’ Equity Requirement. On June 12, 2024, we received a letter from Nasdaq granting an extension (the “Extension Letter”) until September 8, 2024 to demonstrate compliance with the Stockholders’ Equity Requirement in accordance with the terms of the Extension Letter. As previously disclosed, on September 12, 2024, we received a delisting determination letter from Nasdaq advising us that we did not meet the terms of the Extension Letter. As previously disclosed, on September 19, 2024, we submitted a hearing request to the Panel appealing Nasdaq’s delisting determination. We appeared before the Panel on November 5, 2024.

We intend to continue making efforts to regain compliance with the Stockholders’ Equity Requirement. However, there can be no assurance that we will be able to regain compliance with the Stockholders’ Equity Requirement.

Corporate Information

The Company was incorporated in May 2000 as a Utah corporation. In February 2008, Bio-Path Subsidiary completed a reverse merger with the Company, which at the time was traded over the counter

TABLE OF CONTENTS

and had no current operations. The prior name of the Company was changed to Bio-Path Holdings, Inc. and the directors and officers of Bio-Path Subsidiary became the directors and officers of Bio-Path Holdings, Inc. On March 10, 2014, our common stock ceased trading on the OTCQX and commenced trading on the Nasdaq Capital Market under the ticker symbol “BPTH.” Effective December 31, 2014, we changed our state of incorporation from Utah to Delaware through a statutory conversion pursuant to the Utah Revised Business Corporation Act and the Delaware General Corporation Law. Our principal executive offices are located at 4710 Bellaire Boulevard, Suite 210, Bellaire, Texas 77401, and our telephone number is (832) 742-1357.

On February 22, 2024, we effected a reverse stock split of our outstanding shares of common stock at a ratio of 1-for-20, and our common stock began trading on the spilt-adjusted basis on the Nasdaq Capital Market at the commencement of trading on February 23, 2024. As a result of the reverse stock split, approximately 61,000 shares were added to our total shares outstanding due to rounding fractional shares of common stock up to a whole share of common stock. All common stock share and per share amounts in this prospectus have been adjusted to give effect to the 1-for-20 reverse stock split.

Risk Factor Summary

We are providing the following summary of the risk factors disclosed in this prospectus to enhance the readability and accessibility of our risk factor disclosures. These risks are more fully described in the section titled “Risk Factors” immediately following this prospectus summary. We encourage our stockholders to carefully review the risk factors disclosed in this prospectus in their entirety for additional information regarding the material factors that make an investment in the Company speculative or risky.

•

We are a clinical stage biotechnology company with no significant revenue. We have incurred significant operating losses since our inception, and we expect to incur losses for the foreseeable future and may never achieve profitability.

•

We will continue to require substantial additional capital for the foreseeable future. If we are unable to raise additional capital when needed, we may be forced to delay, reduce or eliminate our drug development programs and commercialization efforts.

•

We expect to expand our operations, including clinical trials, in the future and may face challenges in managing our growth, which may result in disruptions to our operations.

•

Our business has a substantial risk of product liability claims. If we are unable to obtain or maintain appropriate levels of insurance, a product liability claim could adversely affect our business.

•

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

•

We face competition from entities that have developed or may develop therapeutic candidates for our target disease indications, including companies developing novel treatments and technology platforms based on modalities and technology that may be similar to ours. If these companies develop technologies, including delivery technologies, or therapeutic candidates more rapidly than we do, or their technologies are more effective, our ability to develop and successfully commercialize therapeutic candidates may be adversely affected.

•

Unstable market and economic conditions may have serious adverse effects on our ability to raise funds, which may cause delays, restructuring or cessation of our operations.

•

Delays in the commencement of clinical trials of our drug candidates could result in increased costs to us and delay our ability to generate revenues.

•

Delays in the completion of, or the termination of, clinical trials of our drug candidates could result in increased costs to us and could delay or prevent us from generating revenues.

TABLE OF CONTENTS

•

If we are unable to obtain U.S. and/or foreign regulatory approval, we will be unable to commercialize our drug candidates.

•

Changes in existing laws and regulations affecting the healthcare industry could increase our costs and otherwise adversely affect our business.

•

We rely on third parties to conduct clinical trials for our drug candidates, and their failure to timely and properly perform their obligations may result in costs and delays that prevent us from obtaining regulatory approval or successfully commercializing our drug candidates.

•

We rely on third parties for manufacturing of our clinical drug supplies; our dependence on these manufacturers may impair the development of our drug candidates.

•

There are underlying risks associated with the manufacture of our drug candidates, which have never been manufactured in large scale. Furthermore, we anticipate continued reliance on third-party manufacturers if we are successful in obtaining marketing approval from the FDA or other regulatory agencies for any of our drug candidates.

•

We may experience delays in the development of our drug candidates if the third-party manufacturers of our drug candidates cannot meet FDA requirements relating to current Good Manufacturing Practices.

•

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our drug candidates, we may not generate product revenue.

•

If our future drugs do not achieve market acceptance, we may be unable to generate significant revenue, if any.

•

If our patent position does not adequately protect our drug candidates, others could compete against us more directly, which would harm our business.

•

If we infringe or are alleged to infringe intellectual property rights of third parties, our business could be harmed.

•

Raising additional capital may cause dilution to existing stockholders, restrict our operations or require us to relinquish rights. Additionally, sales of a substantial number of shares of our common stock or other securities in the public market could cause our stock price to fall.

•

We may issue additional shares of our common stock in accordance with our equity incentive plans or upon exercise or conversion of outstanding securities that are exercisable for or convertible into shares of our common stock, which may cause dilution to existing stockholders.

•

The trading price of our common stock has been volatile and is likely to be volatile in the future.

•

Our common stock is thinly traded and in the future may continue to be thinly traded, and our stockholders may be unable to sell at or near asking prices or at all if they need to sell their shares to raise money or otherwise desire to liquidate such shares.

•

We do not anticipate paying cash dividends, and accordingly stockholders must rely on stock appreciation for any return on their investment in us.

•

Our management is required to devote substantial time and incur additional expense to comply with public company regulations.

•

Our common stock may be delisted from The Nasdaq Capital Market which could negatively impact the price of our common stock and our ability to access the capital markets.

RISK FACTORS

An investment in our company involves a high degree of risk. Before you make a decision to invest in our securities, you should consider carefully the risks described below. Any of these risks could have a material adverse effect on our business, prospects, financial condition and results of operations. In any such case, the trading price of our securities could decline and you could lose all or part of your investment. Additional risks not presently known to us or that we currently deem immaterial may also adversely affect our business operations.

Risks Related to this Offering

You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase.

Since the effective price per share of our common stock being offered is substantially higher than the net tangible book value per share of our common stock, you will suffer substantial dilution in the net tangible book value of the common stock you purchase in this offering. Based on the assumed combined public offering price of $0.769 per share of common stock and accompanying Common Warrants to purchase one share of our common stock being sold in this offering (the last reported sale price per share of our common stock on the Nasdaq Capital Market on February 11, 2025) and our pro forma as adjusted net tangible book value per share as of September 30, 2024, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of approximately $0.11 per share in the net tangible book value of the common stock, after deducting placement agent fees and estimated offering expenses payable by us. See the section titled “Dilution” in this prospectus for a more detailed discussion of the dilution you will incur if you purchase securities in this offering. The description in this paragraph assumes no sale of Pre-Funded Warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis until such warrants are exercised.

If you purchase our securities in this offering, you may experience future dilution as a result of future equity offerings or other equity issuances.

In order to raise additional capital, we believe that we will offer and issue additional shares of our common stock or other securities convertible into or exchangeable for our common stock in the future. We are generally not restricted from issuing additional securities, including shares of common stock, securities that are convertible into or exchangeable for, or that represent the right to receive, common stock or substantially similar securities. As a result of the dilution in net tangible book value to investors purchasing securities in this offering, investors may receive significantly less than the purchase price paid in this offering, if anything, in the event of the liquidation of our company. The issuance of securities in future offerings may cause further dilution to our stockholders, including investors in this offering. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering.

In addition, we have a significant number of stock options and warrants outstanding. To the extent that outstanding stock options or warrants have been or may be exercised or other shares issued, you may experience further dilution. Further, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

If we are required to obtain Warrant Stockholder Approval, until we are able to receive such approval the Common Warrants will not be exercisable, and if we are unable to obtain such approval the Common Warrants will have no value.

The Common Warrants will have an exercise price of $ per share and will be exercisable beginning on the Warrant Stockholder Approval Date; provided, however, if the Pricing Conditions are met, the Common Warrants will be exercisable upon issuance. The Series A Warrant will expire five years from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series A Warrants will expire five years from the date of issuance, the Series B Warrants will expire twenty-four

TABLE OF CONTENTS

months from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series B Warrants will expire twenty-four months from the date of issuance and the Series C Warrants will expire nine months from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series C Warrants will expire nine months from the date of issuance.

If we are required to obtain Warrant Stockholder Approval, the Common Warrants will not be exercisable until, and unless, we obtain the Warrant Stockholder Approval from our stockholders. While we intend to promptly seek the Warrant Stockholder Approval, if required, there is no guarantee that the Warrant Stockholder Approval will ever be obtained. If we are unable to obtain the Warrant Stockholder Approval, the Common Warrants will have no value. In addition, we will incur substantial cost, and management will devote substantial time and attention, in attempting to obtain the Warrant Stockholder Approval.

There may be future sales of our securities or other dilution of our equity, which may adversely affect the market price of our common stock.

With limited exceptions, we are generally not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The market price of our common stock could decline as a result of sales of common stock or securities that are convertible into or exchangeable for, or that represent the right to receive, common stock after this offering or the perception that such sales could occur.

Our management has significant flexibility in using the net proceeds of this offering.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes. Our management will have significant flexibility in applying the net proceeds of this offering and could use them for purposes other than those contemplated at the time of this offering. Management’s failure to use these funds effectively could have an adverse effect on the value of our common stock and could make it more difficult and costly to raise funds in the future. See “Use of Proceeds” on page 45 of this prospectus.

Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers that purchase without the benefit of a securities purchase agreement.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers that enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including, but not limited to: (i) timely delivery of securities; (ii) agreement to not obtaining any financings for seventy-five days from closing; and (iii) indemnification for breach of contract.

Holders of the Pre-Funded Warrants and the Common Warrants offered hereby will have no rights as common stockholders with respect to the shares our common stock underlying the warrants until such holders exercise their warrants and acquire our common stock, except as otherwise provided in the Pre-Funded Warrants and the Common Warrants.

Until holders of the Common Warrants and the Pre-Funded Warrants acquire shares of our common stock upon exercise thereof, such holders will have no rights with respect to the shares of our common stock underlying such warrants, except to the extent that holders of such Common Warrants and Pre-Funded Warrants will have certain rights to participate in distributions or dividends paid on our common stock as set forth in the Common Warrants and the Pre-Funded Warrants. Upon exercise of the Common Warrants and the Pre-Funded Warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

The Common Warrants are speculative in nature, and holders of the Common Warrants offered and sold in this offering will have no rights as common stockholders until such holders exercise their Common Warrants and acquire our common stock.

There can be no assurance that the market price of our common stock will ever equal or exceed the exercise price of the Common Warrants offered and sold in this offering. Consequently, there can be no

TABLE OF CONTENTS

assurance whether it will ever be profitable for holders to exercise their warrants. In addition, until holders of the Pre-Funded Warrants and the Common Warrants offered and sold in this offering acquire shares of our common stock upon exercise of such warrants, holders will have no rights with respect to the shares of our common stock issuable upon exercise of such warrants. Upon exercise of the Pre-Funded Warrants, if any, and the Common Warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

There is no public market for the Pre-Funded Warrants or Common Warrants being offered in this offering.

There is no established public trading market for the Pre-Funded Warrants or Common Warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the Pre-Funded Warrants or Common Warrants on any securities exchange or nationally recognized trading system, including the Nasdaq Capital Market. Without an active market, the liquidity of the Pre-Funded Warrants and Common Warrants will be limited.

Our common stock may be delisted from the Nasdaq Capital Market which could negatively impact the price of our common stock, liquidity and our ability to access the capital markets.

We are currently not in compliance with the continued listing requirements of the Nasdaq Capital Market. The listing standards of the Nasdaq Capital Market provide that a company, in order to qualify for continued listing, must maintain a minimum stock price of $1.00 and satisfy standards relative to minimum stockholders’ equity, minimum market value of publicly held shares and various additional requirements. If we fail to comply with all listing standards applicable to issuers listed on the Nasdaq Capital Market, our common stock may be delisted. If our common stock is delisted, it could reduce the price of our common stock and the levels of liquidity available to our stockholders. In addition, the delisting of our common stock could materially adversely affect our access to the capital markets and any limitation on liquidity or reduction in the price of our common stock could materially adversely affect our ability to raise capital. Delisting from the Nasdaq Capital Market could also result in other negative consequences, including the potential loss of confidence by suppliers, customers and employees, the loss of institutional investor interest and fewer business development opportunities.

As previously reported, on December 12, 2024, we received the Bid Price Letter from the Listing Qualifications Department of Nasdaq indicating that, based upon the closing bid price of our common stock for the last 30 consecutive business days, we did not meet the Minimum Bid Price Rule. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have been provided an initial period of 180 calendar days, or until June 10, 2025, to regain compliance with the Minimum Bid Price Rule. The Bid Price Letter also indicated that if at any time before June 10, 2025 the closing bid price for our common stock is at least $1.00 for a minimum of ten consecutive business days, Nasdaq will provide us with written notification that we comply with the Minimum Bid Price Rule. If we do not regain compliance with the Minimum Bid Price Rule by June 10, 2025, we may be eligible for a second compliance period of 180 calendar days, provided that we meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement, and we notify Nasdaq of our intention to cure the deficiency during such second compliance period, including by effecting a reverse stock split, if necessary. If we do not regain compliance with the Minimum Bid Price Rule by June 10, 2025 and we are not eligible for a second compliance period at that time, Nasdaq will provide us with written notification that our common stock may be delisted. At that time, we may appeal Nasdaq’s delisting determination to a Panel. If we timely appeal, we would remain listed pending the Panel’s decision. There can be no assurance that, if we do appeal the delisting determination by Nasdaq to the Panel, such appeal would be successful. As previously reported, at the Company’s 2024 Annual Meeting, our stockholders approved an amendment to our Certificate of Incorporation to effect a reverse stock split of our common stock at a ratio of up to 1-for-30, to be determined by our board of directors, within twelve months from the date of the 2024 Annual Meeting, subject to the authority of our board of directors to abandon such reverse stock split.

In addition, as previously reported, on November 19, 2024, we received the Stockholders’ Equity Letter from the Panel granting our request for continued listing on the Nasdaq Capital Market in connection with our appeal of the delisting determination to the Panel, subject to certain conditions that must be

TABLE OF CONTENTS

complied with by January 31, 2025. On January 30, 2025, we filed an extension request with the Panel requesting an extension of the January 31, 2025 deadline to February 19, 2025. We must (i) demonstrate compliance with the Stockholders’ Equity Requirement, (ii) publicly disclose compliance with the Stockholder’s Equity Requirement in accordance with the terms of the Stockholders’ Equity Letter and (iii) provide the Panel with income projections for the next twelve months and evidence compliance with all applicable criteria for continued listing on the Nasdaq Capital Market. If we do not satisfy these requirements, we may be subject to delisting. The Panel reserves the right to reconsider the terms of the extension based on any event, condition or circumstance that exists or develops that would, in the opinion of the Panel, make continued listing inadvisable or unwarranted. As previously reported, on March 12, 2024, we received a deficiency letter from the Listing Qualifications Department of Nasdaq notifying us that we are not in compliance with the Stockholders’ Equity Requirement. On June 12, 2024, we received the Extension Letter until September 8, 2024 to demonstrate compliance with the Stockholders’ Equity Requirement in accordance with the terms of the Extension Letter. As previously disclosed, on September 12, 2024, we received a delisting determination letter from Nasdaq advising us that we did not meet the terms of the Extension Letter. As previously disclosed, on September 19, 2024, we submitted a hearing request to the Panel appealing Nasdaq’s delisting determination. We appeared before the Panel on November 5, 2024. There can be no assurance that we will be able to regain compliance with the Stockholders’ Equity Requirement, or any other applicable requirements for continued listing on the Nasdaq Capital Market, or that we will be able to maintain such compliance in the future.

Resales of our shares of common stock in the public market by our stockholders as a result of this offering may cause the market price of our shares of common stock to fall.

We are registering 13,003,901 shares of common stock, as well as 52,015,604 shares of common stock, in the aggregate, issuable upon the exercise of the Pre-Funded Warrants and the Common Warrants offered under this prospectus. Sales of substantial amounts of our shares of common stock in the public market, or the perception that such sales might occur, could adversely affect the market price of our shares of common stock. The issuance of new shares of common stock could result in resales of our shares of common stock by our current stockholders concerned about the potential ownership dilution of their holdings. Furthermore, in the future, we may issue additional shares of common stock or other equity or debt securities exercisable or convertible into shares of common stock. Any such issuance could result in substantial dilution to our existing shareholders and could cause our stock price to decline.

Even if this offering is successful, we will need to raise additional capital in the future to continue operations, which may not be available on acceptable terms, if at all. Failure to obtain necessary capital when needed may force us to delay, limit or terminate our drug development efforts or other operations.

As of September 30, 2024, we had an accumulated deficit of $114.7 million. To date, we have not generated any revenue from the sale of our drug candidates and we do not expect to generate any revenue from sales of our drug candidates for the foreseeable future. We expect to continue to incur significant operating losses and we anticipate that our losses may increase substantially as we expand our drug development programs and commercialization efforts. As of September 30, 2024, we had a cash balance of $0.6 million. We do not believe that our available cash at September 30, 2024, together with the net proceeds received from the October 2024 Private Placement, will be sufficient to fund current liabilities and capital expenditure requirements for the next 12 months from November 14, 2024, the filing date of our Form 10-Q for the nine months ended September 30, 2024. The Company’s ability to continue as a going concern is dependent upon obtaining funding through one or more sources described below within the next 12 months to meet its planned obligations and pay its liabilities. Even if this offering is successful, we must raise additional funds in order to continue operating our business.

We may finance our foreseeable cash requirements through cash on hand, debt financings and public or private equity offerings. Additionally, we may seek collaborations and license arrangements for our drug candidates. We may seek to access the public or private equity markets whenever conditions are favorable. We currently have no lines of credit or other arranged access to debt financing. If we are unable to obtain funding due to unfavorable terms or market conditions, management has determined that it can reduce spending on its day-to-day operations, sell laboratory assets and temporarily delay planned activities if needed. However, our ability to continue as a going concern is dependent upon obtaining funding through

TABLE OF CONTENTS

one or more sources described above within the next 12 months to meet our planned obligations and pay our liabilities. We estimate that we will receive net proceeds of approximately $8.9 million from the sale of the securities offered by us in this offering, based on the assumed combined public offering price of $0.769 per share (the last reported sale price per share of our common stock on the Nasdaq Capital Market on February 11, 2025) and after deducting the estimated Placement Agent fees and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the Pre-Funded Warrants and Common Warrants issued pursuant to this offering. In the event of a decrease in the net proceeds to us from this offering as a result of a decrease in the assumed combined public offering price or the number of shares offered by us, we may need to raise additional capital sooner than we anticipate. In addition, we cannot provide assurances that our plans will not change or that changed circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate.

Our ongoing future capital requirements will depend on numerous factors, including:

•

the rate of progress, results and costs of completion of ongoing clinical trials of our drug candidates;

•

the rate of progress, results and costs of completion of ongoing preclinical testing of our drug candidates;

•

the size, scope, rate of progress, results and costs of completion of any potential future clinical trials and preclinical tests of our drug candidates that we may initiate;

•

the costs to obtain adequate supply of the compounds necessary for our drug candidates;

•

the costs of obtaining regulatory approval of our drug candidates;

•

the scope, prioritization and number of drug development programs we pursue;

•

the costs for preparing, filing, prosecuting, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

•

the extent to which we acquire or in-license other products and technologies and the costs to develop those products and technologies;

•

the costs of future commercializing activities, including product sales, marketing, manufacturing and distribution, of any of our drug candidates or other products for which marketing approval has been obtained;

•

our ability to establish strategic collaborations and licensing or other arrangements on terms favorable to us; and

•

competing technological and market developments.

Any additional fundraising efforts may divert our management from their day to day activities, which may adversely affect our ability to develop and commercialize our drug candidates. Our ability to raise additional funds will depend, in part, on the success of our product development activities and other factors related to financial, economic and market conditions, many of which are beyond our control. There can be no assurance that we will be able to raise additional capital when needed or on terms that are favorable to us, if at all. If adequate funds are not available on a timely basis, we may be forced to:

•

delay, reduce the scope of or eliminate one or more of our drug development programs;

•

relinquish, license or otherwise dispose of rights to technologies, drug candidates or products that we would otherwise seek to develop or commercialize ourselves at an earlier stage or on terms that are less favorable than might otherwise be available; or

•

liquidate and dissolve the Company.

If our operating plans change, we may require additional capital sooner than planned. Such additional financing may not be available when needed or on terms favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current and future operating plan.

This is a best efforts offering, no minimum amount of securities is required to be sold.

The Placement Agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities being offered in this offering. The Placement Agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities or amount of proceeds that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, Placement Agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth above. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to fund for our operations, as described under the heading “Use of Proceeds” on page 45 of this prospectus.

Risks Related to Our Business

We have incurred significant operating losses since our inception. As of September 30, 2024, we had an accumulated deficit of $114.7 million. To date, we have not generated any revenue from the sale of our drug candidates and we do not expect to generate any revenue from sales of our drug candidates for the foreseeable future. We expect to continue to incur significant operating losses and we anticipate that our losses may increase substantially as we expand our drug development programs and commercialization efforts.

To achieve profitability, we must successfully develop and obtain regulatory approval for one or more of our drug candidates and effectively commercialize any drug candidates we develop. Even if we succeed in developing and commercializing one or more of our drug candidates, we may not be able to generate sufficient revenue and we may never be able to achieve or sustain profitability.

As of September 30, 2024, we had $0.6 million in cash on hand. We have determined that the Company’s available cash as of September 30, 2024, together with the net proceeds received from the October 2024 Private Placement, will not be sufficient to fund current liabilities and capital expenditure requirements for the next 12 months from November 14, 2024, the filing date of our Form 10-Q for the nine months ended September 30, 2024. Our ongoing future capital requirements will depend on numerous factors, including:

•

the rate of progress, results and costs of completion of ongoing clinical trials of our drug candidates;

•

the rate of progress, results and costs of completion of ongoing preclinical testing of our drug candidates;

•

the size, scope, rate of progress, results and costs of completion of any potential future clinical trials and preclinical tests of our drug candidates that we may initiate;

•

the costs to obtain adequate supply of the compounds necessary for our drug candidates;

•

the costs of obtaining regulatory approval of our drug candidates;

•

the scope, prioritization and number of drug development programs we pursue;

•

the costs for preparing, filing, prosecuting, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

•

the extent to which we acquire or in-license other products and technologies and the costs to develop those products and technologies;

•

our ability to establish strategic collaborations and licensing or other arrangements on terms favorable to us; and

•

competing technological and market developments.

•

delay, reduce the scope of or eliminate one or more of our drug development programs;

•

liquidate and dissolve the Company.

The report of our independent registered public accounting firm contains an emphasis of a matter regarding substantial doubt about our ability to continue as a going concern.

The report of our independent registered public accounting firm relating to our December 31, 2023 consolidated financial statements contains an emphasis of a matter regarding substantial doubt about our ability to continue as a going concern. As discussed in Note 2 to the consolidated financial statements included herein, we have suffered recurring losses from operations and have a projected cash deficiency that raise substantial doubt about our ability to continue as a going concern. The consolidated financial statements have been prepared assuming we will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty.

We have determined that the Company’s available cash as of September 30, 2024, together with the net proceeds received from the October 2024 Private Placement will not be sufficient to fund current liabilities and capital expenditure requirements for the next 12 months from November 14, 2024, the filing date of our Form 10-Q for the nine months ended September 30, 2024. We may finance our foreseeable cash requirements through cash on hand, debt financings and public or private equity offerings. Additionally, we may seek collaborations and license arrangements for our drug candidates. We may seek to access the public or private equity markets whenever conditions are favorable. We currently have no lines of credit or other arranged access to debt financing. If we are unable to obtain funding due to unfavorable terms or market conditions, management has determined that it can reduce spending on its day-to-day operations, sell laboratory assets and temporarily delay planned activities if needed. However, our ability to continue as a going concern is dependent upon obtaining funding through one or more sources described above to meet our planned obligations and pay our liabilities.

TABLE OF CONTENTS

The pharmaceutical and biotechnology industry is highly competitive. If we are unable to compete effectively, our drug candidates may be rendered noncompetitive or obsolete.

We are engaged in segments of the pharmaceutical and biotechnology industry that are highly competitive and characterized by rapid and significant technological change. Many large pharmaceutical and biotechnology companies, academic and research institutions, governmental agencies and other public and private research organizations are pursuing the development of novel drugs that target AML, CML, ALL, MDS, lymphoma, ovarian, breast cancer, solid tumors and other cancers generally. We face, and expect to continue to face, intense and increasing competition as new products enter the market and advanced technologies become available. Our competitors may discover, develop or commercialize products or other novel technologies that are more effective, safer or less costly than our drug candidates. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our drug candidates.

Many of our competitors have:

•

significantly greater capital, technical and human resources than we have and may be better equipped to discover, develop, manufacture and commercialize drug candidates;

•

more experience in drug discovery, development and commercialization, obtaining regulatory approvals and manufacturing and marketing pharmaceutical products;

•

drug candidates that have been approved or are in late-stage clinical development; and/or

•

collaboration arrangements in our target markets with leading companies and research institutions.

Mergers and acquisitions in the pharmaceutical and biotechnology industry may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patent registration for clinical trials, and acquiring technologies complementary to, or necessary for, our drug candidates and programs.

Competitive products and technological developments may render our drug candidates noncompetitive or obsolete before we can recover the expenses of developing and commercializing our drug candidates. Furthermore, the development of new treatment methods and/or the widespread adoption or increased utilization of any vaccine for the diseases we are targeting could render our drug candidates noncompetitive, obsolete or uneconomical. If we successfully develop and obtain approval for any of our drug candidates, we will face competition based on the safety and effectiveness of our drug candidates, the timing of their entry into the market in relation to competitive products in development, the availability and cost of supply, marketing and sales capabilities, reimbursement coverage, price, patent position and other factors. If we successfully develop drug candidates but those drug candidates do not achieve and maintain market acceptance, our business will not be successful.

Future collaboration arrangements to leverage our capabilities may not be successful.

As part of our business strategy, we may enter into collaborative arrangements for the development and commercialization of our drug candidates. For our collaboration efforts to be successful, we must identify partners whose competencies complement ours. We must also successfully enter into collaboration agreements with them on terms attractive to us and integrate and coordinate their resources and capabilities with our own. We may be unsuccessful in entering into collaboration agreements with acceptable partners or negotiating favorable terms in these agreements. In addition, we may face a disadvantage in seeking to enter into or negotiating collaborations with potential partners because other potential collaborators may have greater management and financial resources than we do.

If we do enter into collaborative arrangements, the success of these collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Furthermore, we may face risks and uncertainties in connection with collaborative arrangements, including:

•

inability to integrate the resources or capabilities of collaborators;

TABLE OF CONTENTS

•

collaborators may prove difficult to work with or less skilled than we originally expected;

•

disputes may arise with respect to the ownership of rights to technology developed with collaborators;

•

disagreements with collaborators could delay or terminate the research, development or commercialization of products or result in litigation or arbitration;

•

difficulty enforcing our arrangements if one of our collaborators fails to perform;

•

termination of our collaboration arrangements by collaborators, which could make it difficult for us to attract new collaborators or adversely affect the perception of us in the business or financial communities;

•

collaborators may have considerable discretion in electing whether to pursue the development of any additional drug candidates and may pursue technologies or products either on their own or in collaboration with our competitors that are similar to or competitive with our technologies; and

•

collaborators may change the focus of their development and commercialization efforts.

If we are unsuccessful in our collaborative efforts, our ability to develop and market drug candidates could be severely limited.

If we are unable to attract and retain key management, scientific personnel and advisors, we may not successfully develop our drug candidates or achieve our other business objectives.

Our success depends on the availability and contributions of members of our senior management team, scientific team and other key personnel. The loss of services of any of these individuals could delay, reduce or prevent our drug development and other business objectives. Furthermore, recruiting and retaining qualified scientific personnel to perform drug development work will be critical to our success. We face intense competition for qualified individuals from numerous pharmaceutical and biotechnology companies, universities, governmental entities and other public and private research institutions. We may be unable to attract and retain these individuals, and our failure to do so could materially adversely affect our business and financial condition.

Our employees, agents, consultants and commercial partners may engage in misconduct or other improper activities, including non-compliance with applicable regulatory standards and requirements.

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants, advisors and commercial partners. Misconduct by these persons could include intentional failures to comply with the regulations of the FDA and non-U.S. regulators, comply with healthcare fraud and abuse laws and regulations in the U.S. and abroad, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct could involve the improper use of information obtained in the course of clinical studies, which could result in regulatory sanctions and cause serious harm to our business, financial condition and reputation. We currently have codes of business conduct and ethics applicable to all of our employees, but it is not always possible to identify and deter employee misconduct, and our codes of business conduct and ethics and the other precautions we take to detect and prevent improper activities may not be effective in controlling unknown or unmanaged risks or losses, or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could result in the imposition of significant fines or other sanctions, which could materially adversely affect our business and financial condition. Whether or not we are successful in defending against such actions or investigations, we could incur substantial costs, including legal fees, and divert the attention of management in defending ourselves against any of these claims or investigations.

TABLE OF CONTENTS

We expect to expand our operations, including clinical trials, in the future and may face challenges in managing our growth, which may result in disruptions to our operations.

We expect to expand our operations, including clinical trials for our drug candidates, over time. To successfully manage future growth, we may need to implement and improve our managerial, operational and financial resources, and may need to expand our facilities and recruit and train additional qualified personnel. Our expected growth may also require significant financial resources, which may not be available when needed or on terms favorable to us. Our senior management may be required to devote substantial attention to managing growth activities and may be unable to effectively manage the expansion of our operations due to our limited resources, which may result in disruptions to our business operations and could harm our business and financial condition.

If we acquire or license technologies, resources or drug candidates, we will incur a variety of costs and may never realize benefits from the transaction.

If appropriate opportunities become available, we may license or acquire technologies, resources, drugs or drug candidates. We may never realize the anticipated benefits of such a transaction. In particular, due to the risks inherent in drug development, we may not successfully develop or obtain marketing approval for the drug candidates we acquire. Future licenses or acquisitions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, the creation of contingent liabilities, material impairment expenses related to goodwill and impairment or amortization expenses related to other intangible assets, which could harm our business and financial condition.

Our business has a substantial risk of product liability claims. If we are unable to obtain or maintain appropriate levels of insurance, a product liability claim could adversely affect our business.

Our business exposes us to significant potential product liability risks that are inherent in the development, manufacturing and sales and marketing of human therapeutic products. Although we do not currently commercialize any products, claims could be made against us based on the use of our drug candidates in clinical trials. Product liability claims could delay or prevent completion of our clinical development programs. We currently have product liability insurance, but we may not be able to maintain such insurance on acceptable terms. However, even if we maintain or obtain other product liability insurance, our insurance may not provide adequate coverage against potential liabilities. As a result, we may be unable to obtain or maintain insurance coverage at a reasonable cost to protect against losses that could harm our business and financial condition. If any claims are brought against us, and we are not successful in defending ourselves, those claims could result in damage awards against us, which could materially adversely affect our business and financial condition. Whether or not we are successful in defending against such claims, we could incur substantial costs, including legal fees, and divert the attention of management in defending ourselves against any of these claims.

We are increasingly dependent on information technology systems to operate our business and a cyber-attack or other breach of our systems, or those of third parties on whom we may rely, could subject us to liability or interrupt the operation of our business.

We are increasingly dependent on information technology systems to operate our business. A breakdown, invasion, corruption, destruction or interruption of critical information technology systems by employees, others with authorized access to our systems or unauthorized persons could negatively impact operations. In the ordinary course of business, we collect, store and transmit confidential information and it is critical that we do so in a secure manner to maintain the confidentiality and integrity of such information. Additionally, we outsource certain elements of our information technology systems to third parties. As a result of this outsourcing, our third party vendors may or could have access to our confidential information making such systems vulnerable. Data breaches of our information technology systems, or those of our third party vendors, may pose a risk that sensitive data may be exposed to unauthorized persons or to the public. For example, the loss of clinical trial data from completed or ongoing clinical trials or preclinical studies could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. While we believe that we have taken appropriate security measures to protect our data and information technology systems, and have been informed by our third party vendors that they have

as well, there can be no assurance that our efforts will prevent breakdowns or breaches in our systems, or those of our third party vendors, that could materially adversely affect our business and financial condition.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation experiences an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to utilize its pre-change net operating loss carryforwards and other pre-change tax attributes (such as research tax credits) to offset its post-change taxable income or taxes may be limited. Our prior and potential future equity offerings and other changes in our stock ownership, some of which are outside of our control, may have resulted or could in the future result in an ownership change under Section 382 of the Code. If a limitation were to apply, utilization of a portion of our domestic net operating loss and tax credit carryforwards could be limited in future periods and a portion of the carryforwards could expire before being available to reduce future income tax liabilities.

On December 22, 2017, the U.S. government enacted legislation referred to as the Tax Cuts and Jobs Act (the “Tax Act”). Under the Tax Act, net operating losses generated prior to 2018 will continue to be governed by the net operating loss tax rules as they existed prior to the adoption of the new Tax Act, which means that generally they will expire 20 years after they were generated if not used prior thereto. Accordingly, our net operating losses could expire unused and be unavailable to offset future income tax liabilities, if any. Under the Tax Act, net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such net operating losses is limited to 80% of current year taxable income. We continue to examine the impact that this provision of the Tax Act, among other provisions, may have on our business.

Provisions of our charter documents or Delaware law could delay or prevent an acquisition of our company, even if the acquisition would be beneficial to our stockholders, and could make it more difficult to change management.

Provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders might otherwise consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. In addition, these provisions may frustrate or prevent any attempt by our stockholders to replace or remove our current management by making it more difficult to replace or remove our board of directors. These provisions include:

•

limitations on our stockholders’ ability to call special meetings of stockholders;

•

an advance notice requirement for stockholder proposals and nominations for members of our Board;

•

the authority of our Board to determine the number of director seats on our Board;

•

the authority of our Board to fill vacancies occurring on the Board;

•

the authority of our Board to issue preferred stock with such terms as our Board may determine.

In addition, because we are governed by Delaware law, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person who, together with its affiliates, owns or within the last three years has owned 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

While we believe that our DNAbilize® technology is the only delivery method of its type, the area of cancer treatment research is rapidly progressing, with many stakeholders, including for-profit and nonprofit

TABLE OF CONTENTS

institutions, conducting preclinical and clinical studies of various types of therapeutic products for the same or similar indications for use as our drug candidates. We expect that such work by others will continue, which may make it difficult for us to effectively recruit and enroll a satisfactory number of participants in clinical trials.

Our success will partially depend on our ability to develop therapeutics that are safer and more effective than competing therapeutics. Our commercial opportunity and success will be reduced or eliminated if competing therapeutics are safer, more effective, or less expensive than the therapeutics we develop, or if any are granted exclusive marketing approval by the FDA that precludes the marketing of our drug candidates for a period of time. If our lead drug candidates are approved for the indications we are currently pursuing, they will compete with a range of therapeutic treatments that are either in development or currently marketed. For example, the FDA has recently approved a number of drugs indicated for treatment of AML, some of which may have target patient populations similar to that of our drug candidates.

Many of our competitors may have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain FDA approval for any drug candidate, we will face competition based on many different factors, including the safety and effectiveness of our products, the ease with which our products can be administered, the timing and scope of regulatory approvals (if we are able to obtain any) for these drug candidates, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing therapeutics could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any therapeutics we may develop. Competitive alternatives may make any drugs that we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our drug candidates, if we are able to obtain regulatory approval to commercialize such drug candidates.

We may be subject, directly or indirectly, to certain U.S. federal and state healthcare laws and regulations, such as anti-kickback, false claims laws, physician payment transparency laws or similar fraud and abuse laws, which could expose us to potential criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians and others will play a primary role in the recommendation, ordering and utilization of any products for which we obtain regulatory approval. If we obtain FDA approval for any of our products and begin commercializing those products in the U.S., our operations may be subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act, and physician payment transparency laws and regulations. These laws may impact, among other things, our potential sales, marketing and education programs and our relationships with physicians, patients, and other persons or entities in a position to refer, use, or recommend our future products. The laws that may affect our ability to operate could include, but are not limited to:

•

the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual, or the purchase, lease, order or recommendation of any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs;

•

federal civil and criminal false claims laws and civil monetary penalty laws, including the False Claims Act, which may be pursued through civil whistleblower or qui tam actions, impose criminal and civil penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval from Medicare, Medicaid or other third-party payors that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;

•

federal criminal statutes under the Health Insurance Portability and Accountability Act of 1996, which prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, and knowingly and willfully falsifying, concealing or covering up by any trick or

TABLE OF CONTENTS

device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters;

•

the federal transparency requirements under The Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act (known collectively as the “Affordable Care Act”), including the provision commonly referred to as the Physician Payments Sunshine Act, which requires manufacturers of drugs, biologics, devices and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program to report annually to the Centers for Medicare and Medicaid Services information related to payments or other transfers of value made to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and

•

State law equivalents of each of the healthcare laws described above, some of which may be broader in scope and apply regardless of the type of payor, such as state anti-kickback statutes and false claims acts, and state pricing, marketing, and transparency statutes that require us to adopt compliance programs, report pricing information, or disclose payments or other transfers of value to physicians or other covered recipients.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws once our products are commercialized. In addition, healthcare reform legislation has strengthened these laws and additional laws or requirements may be implemented in the future. For example, the Affordable Care Act, among other things, amended the intent requirement of the federal Anti-Kickback and criminal healthcare fraud statutes. As a result of such amendment, a person or entity no longer needs to have actual knowledge of these statutes or specific intent to violate them in order to have committed a violation. Moreover, the Affordable Care Act provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

Efforts to ensure that our business arrangements comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our existing or future business practices do not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. Any such actions instituted against us could have a significant adverse impact on our business, including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations. Even if we are successful in defending against such actions, we may nonetheless be subject to substantial costs, reputational harm and adverse effects on our ability to operate our business.

If any of our employees, agents, or the physicians or other providers or entities with whom we expect to do business are found to have violated applicable laws, we may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs, or, if we are not subject to such actions, we may suffer reputational harm for conducting business with persons or entities found, or accused of being, in violation of such laws. Any such events could adversely affect our ability to operate our business and our results of operations.

Inadequate funding for the FDA, the SEC and other government agencies, or a work slowdown or stoppage at those agencies as part of a broader federal government shutdown, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government

agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which could adversely affect our business. For example, in recent years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough employees and stop critical activities. If a prolonged government shutdown or a series of shutdowns occurs, it could significantly affect the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to gain access to the public markets and obtain necessary capital in order to properly capitalize and continue our operations, which could have a material adverse effect on our business and financial condition.

Our business and operations have been affected by and could be materially and adversely affected in the future by the effects of health epidemics and pandemics, including the evolving and ongoing effects of the COVID-19 pandemic.

Our business and operations could be adversely affected by health epidemics and pandemics, including the ongoing COVID-19 pandemic, which has presented a substantial public health and economic challenge around the world and has affected, and continues to affect, our employees, clinical trial participants, communities, and business operations, as well as the U.S. and global economy and financial markets. To date, COVID 19’s impact on our operations has been limited to the inability to travel to clinical trial sites, clinical trial sites not allowing nonessential personnel on site for the purpose of monitoring activity, delays in the manufacture of our drug requirements by contracted third-party manufacturers and limitations on patient recruiting and enrollment. There can be no guarantee we will not experience other impacts, such as being forced to further delay or pause enrollment, experiencing potential interruptions to our supply chain, facing difficulties or additional costs in enrolling patients in future clinical trials or being able to achieve full enrollment of our studies within the timeframes we anticipate, or at all.

The negative impacts caused by the COVID-19 pandemic have been and may continue to be extensive in many aspects of society and could continue to result in significant disruptions to the global economy, as well as businesses and capital markets around the world. The full extent to which the COVID-19 pandemic could ultimately impact our business, preclinical studies, clinical trials and financial results will depend on future developments, which are highly uncertain and cannot be accurately predicted, including the emergence of new variants and subvariants of the virus that causes COVID-19.

Other public health crises, including any future outbreaks of contagious diseases, could have additional material adverse effects on our business. The extent to which any future public health crises may impact our business, results of operations, and financial condition depends on many factors which are highly uncertain and are difficult to predict. These factors include, but are not limited to, the duration and spread of any outbreak, its severity, the actions to contain or address the impact of the outbreak, the timing, distribution, and efficacy of vaccines and other treatments, United States and foreign government actions to respond to possible reductions in global economic activity, and how quickly and to what extent normal economic and operating conditions can resume.

Unstable market and economic conditions may have serious adverse effects on our ability to raise funds, which may cause delays, restructuring or cessation of our operations.

From time to time, global and domestic credit and financial markets have experienced extreme disruptions, including severely diminished liquidity and credit availability, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make a debt or equity financing more difficult to complete, costlier, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms will have a material adverse effect on our business strategy and financial condition, and could require us to liquidate and dissolve the Company.

Risks Related to the Development of Our Drug Candidates

We must complete extensive clinical trials to demonstrate the safety and efficacy of our drug candidates. If we are unable to demonstrate the safety and efficacy of our drug candidates, we will not obtain the regulatory approval necessary to market our drug candidates, which would have an adverse effect on our business.

To date, none of our drug candidates have been approved for sale in the U.S. or any foreign country. Before a new drug product can be marketed, it must obtain clearance from the FDA by submitting an investigational new drug application (“IND”), then by successfully completing human testing under three phases of clinical trials, and finally by submitting a new drug application (“NDA”).

Before an entity can begin clinical trials for a product candidate in the U.S., they must complete extensive nonclinical and preclinical studies that support their planned and future INDs. We cannot be certain of the timely completion or outcome of ongoing and future nonclinical and preclinical studies and cannot predict if the FDA will allow our future proposed clinical programs to proceed or if the outcome of their nonclinical and preclinical studies will ultimately support further development of our programs. We also cannot be sure that we will be able to submit INDs or similar applications with respect to our future product candidates on the timelines we expect, if at all, and we cannot be sure that submission of IND or similar applications will result in the FDA or other regulatory authorities allowing clinical trials to begin. With respect to INDs we have already obtained or are able to obtain in the future, we cannot be sure that our clinical trials will be successful to the satisfaction of the FDA.

For purposes of NDA approval by the FDA, human clinical trials are typically conducted in the following phases (which may overlap):

•

Phase 1: The investigational product is initially given to healthy human subjects or patients and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. These trials may also provide early evidence on effectiveness. During Phase 1 clinical trials, sufficient information about the investigational product’s pharmacokinetics and pharmacologic effects may be obtained to permit the design of well-controlled and scientifically valid Phase 2 clinical trials.

•

Phase 2: These clinical trials are conducted in a limited number of human subjects in the target population to identify possible adverse effects and safety risks, to determine the efficacy of the investigational product for specific targeted diseases and to determine dosage tolerance and dosage levels. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more costly Phase 3 clinical trials.

•

Phase 3: Phase 3 clinical trials are undertaken after Phase 2 clinical trials demonstrate that a dosage range of the investigational product appears effective and has a tolerable safety profile. The Phase 2 clinical trials must also provide sufficient information for the design of Phase 3 clinical trials. Phase 3 clinical trials are conducted to provide statistically significant evidence of clinical efficacy and to further test for safety risks in an expanded human subject population at multiple clinical trial sites. These clinical trials are intended to further evaluate dosage, effectiveness and safety, to establish the overall benefit-risk profile of the investigational product and to provide an adequate basis for product labeling and approval by the FDA. In most cases, the FDA requires two adequate and well-controlled Phase 3 clinical trials to demonstrate the efficacy of an investigational drug or biologic.

All clinical trials must be conducted in accordance with FDA regulations, GCP requirements and their protocols in order for the data to be considered reliable for regulatory purposes. Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. These government regulations may delay or prevent approval of product candidates for a considerable period of time and impose costly procedures upon our business operations.

The FDA may require, or companies may pursue, additional clinical trials, referred to as Phase 4 clinical trials, after a product is approved. Such trials may be made a condition to be satisfied for continuing drug approval. The results of Phase 4 clinical trials can confirm the effectiveness of a product candidate and can provide important safety information. In addition, the FDA has authority to require sponsors to conduct post-marketing trials to specifically address safety issues identified by the agency.

TABLE OF CONTENTS

While antisense therapeutics have been in development for over 20 years, only a limited number of antisense drugs have been successfully developed to date. Further, the development of liposomal antisense therapeutics, which comprise our drug therapeutics technology, has faced many challenges and generally remains unproven in the treatment of cancers. The success of our business depends primarily on our ability to develop and commercialize our drug candidates successfully. In order to obtain FDA approval to market a new drug in the U.S., our drug candidates must satisfy rigorous standards of safety and efficacy to the satisfaction of the FDA before they may be approved for sale. In an effort to satisfy these standards, we must engage in expensive and lengthy testing of our drug candidates.

We may not be able to obtain authority from the FDA or other equivalent foreign regulatory agencies to move on to further efficacy segments of our ongoing clinical trials or commence and complete any other clinical trials for any of our drug candidates. Positive results in preclinical studies of a drug candidate may not be predictive of similar results in human clinical trials, and promising results from early clinical trials of a drug candidate may not be replicated in later clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after achieving promising results in early-stage development. Accordingly, the results from the preclinical tests or clinical trials for our drug candidates may not be predictive of the results we may obtain in later stage trials. The failure of clinical trials to demonstrate safety and efficacy of one or more of our drug candidates will have a material adverse effect on our business and financial condition for any number of reasons including delays in development, additional unanticipated studies required by the FDA, or an ultimate inability to market a product candidate and generate a profit.

Delays in the commencement of clinical trials of our drug candidates could result in increased costs to us and delay our ability to generate revenues.

Our drug candidates will require continued extensive clinical trials prior to the submission of a regulatory application for commercial sales. Because of the nature of clinical trials, we do not know whether future planned clinical trials will begin on time, if at all. Delays in the commencement of clinical trials could significantly increase our drug development costs and delay any commercialization of our drug candidates. In addition, many of the factors that may cause, or lead to, a delay in the commencement of clinical trials may also ultimately lead to denial of regulatory approval of a drug candidate.

The commencement of clinical trials can be delayed for a variety of reasons, including delays in:

•

demonstrating sufficient safety and efficacy in past clinical trials to obtain regulatory approval to commence a further clinical trial;

•

convincing the FDA that we have selected valid endpoints for use in proposed clinical trials;

•

reaching agreements on acceptable terms with prospective contract manufacturers for manufacturing sufficient quantities of our drug candidates; and

•

obtaining institutional review board approval to conduct a clinical trial at a prospective site.

In addition, the commencement of clinical trials may be delayed due to insufficient patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease and the eligibility criteria for the clinical trial.

Delays in the completion of, or the termination of, clinical trials of our drug candidates could result in increased costs to us and could delay or prevent us from generating revenues.

Once a clinical trial has begun, it may be delayed, suspended or terminated by us or the FDA or other regulatory authorities due to a number of factors, including:

•

regulators or institutional review boards may not authorize us to commence or conduct a clinical trial at a prospective trial site;

•

our preclinical tests or clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional preclinical testing or clinical trials or we may abandon projects that we expect may not be promising;

TABLE OF CONTENTS

•

we might have to suspend or terminate our clinical trials if the participating patients are being exposed to unacceptable health risks;

•

regulators or institutional review boards may require that we hold, suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements;

•

the cost of our clinical trials may be greater than we currently anticipate and we may lack adequate funding to continue the clinical trial;

•

the timing of our clinical trials may be longer than we currently anticipate;

•

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner (including delays or inability to manufacture or obtain sufficient quantities of materials for use in clinical trials);

•

inadequacy of or changes in our manufacturing process or compound formulation;

•

slower than expected rates of patient recruitment and enrollment or lower than expected patient retention rates;

•

the effects of our drug candidates may not be the desired effects or may include undesirable side effects or our drug candidates may have other unexpected characteristics;

•

changes in applicable regulatory policies and regulations;

•

delays in identifying and reaching agreement on acceptable terms with prospective clinical trial sites;

•

uncertainty regarding proper dosing;

•

failure of our clinical research organizations to comply with all regulatory and contractual requirements or otherwise fail to perform their services in a timely or acceptable manner;

•

scheduling conflicts with participating clinicians and clinical institutions;

•

failure to construct appropriate clinical trial protocols;

•

insufficient data to support regulatory approval;

•

inability or unwillingness of medical investigators to follow our clinical protocols; and

•

the timing of discussions and meetings with the FDA or other regulatory authorities regarding the scope or design of our clinical trials.

Many of these factors that may lead to a delay, suspension or termination of clinical trials of our drug candidates may also ultimately lead to denial of regulatory approval of our drug candidates.

From time to time, we may publicly announce our expected timing of completing certain milestones relating to various scientific, clinical, regulatory, development and other objectives related to our business. For example, these milestones may include the commencement or completion of scientific studies or clinical trials or the submission or approval of regulatory filings. Our estimates for completion of these milestones are based on a variety of assumptions, some of which may be out of our control.

If we experience delays in the completion of, or termination of, clinical trials of any drug candidates in the future, or if we do not meet our milestones within the estimated timeframes that we have publicly announced, our business, financial condition and the commercial prospects for our drug candidates could be materially adversely affected, and our ability to generate product revenues could be delayed or eliminated. In addition, our stock price could decline.

If we are unable to obtain U.S. and/or foreign regulatory approval, we will be unable to commercialize our drug candidates.

Our drug candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, record keeping, labeling, marketing and distribution of drugs. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required in the U.S. and in many foreign jurisdictions prior to the commercial sale of our drug

TABLE OF CONTENTS

candidates. Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. It is possible that none of the drug candidates we are developing will obtain marketing approval. In connection with the clinical trials for our drug candidates, we face risks that:

•

the drug candidate may not prove to be sufficiently efficacious;

•

the drug candidate may not prove to be safe;

•

the drug candidate may not be readily co-administered or combined with other drugs or drug candidates;

•

the results may not confirm the positive results from earlier preclinical studies or clinical trials;

•

the results may not meet the level of statistical significance required by the FDA or other regulatory agencies; and

•

the FDA or other regulatory agencies may require us to carry out additional studies.

We have limited experience in conducting and managing later stage clinical trials necessary to obtain regulatory approvals, including approval by the FDA. However, this risk would be mitigated in the event the Company is successful entering into a co-development agreement with a pharma partner for late stage clinical development. The time required to complete clinical trials and for the FDA and other countries’ regulatory review processes is uncertain and typically takes many years. Our analysis of data obtained from preclinical and clinical trials is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unanticipated delays or increased costs due to government regulation from future legislation or administrative action or changes in FDA policy during the period of product development, clinical trials, and FDA regulatory review.

Any regulatory approval to market a product may be subject to limitations on the indicated uses for which we may market the product and affect reimbursement by third-party payors. These limitations may limit the size of the market for the product. We may also become subject to numerous foreign regulatory requirements governing the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process includes all of the risks associated with FDA approval described above as well as risks attributable to the satisfaction of foreign regulations. Approval by the FDA does not ensure approval by regulatory authorities outside the U.S. Foreign jurisdictions may have different approval procedures than those required by the FDA and may impose additional testing requirements for our drug candidates.

Even if we are successful in obtaining regulatory approval to market a drug candidate, we, and our third-party manufacturer(s) will be, subject to extensive regulation by the FDA.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, manufacturing processes or facilities, require submission and FDA approval of a new NDA, or an NDA supplement, before the change can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs.

Drug products must also comply with applicable requirements, including monitoring and recordkeeping activities, manufacturing requirements, reporting to the applicable regulatory authorities of adverse experiences with the product, providing the regulatory authorities with updated safety and efficacy information, product sampling and distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the drug’s approved labeling, or off-label use, limitations on industry-sponsored scientific and educational activities and requirements for promotional activities involving the internet. Although physicians may, in their independent professional medical judgment, prescribe legally available drugs for off-label uses, manufacturers typically may not market or promote such off-label uses.

TABLE OF CONTENTS

In addition to regulations in the U.S., we may be subject to a variety of regulations in other jurisdictions governing, among other things, clinical trials and any commercial sales and distribution of our products, if approved.

Whether or not we obtain FDA approval for a drug candidate, we must obtain the requisite approvals from regulatory authorities in non-U.S. countries prior to the commencement of clinical trials or marketing of our products in those countries. Certain countries outside of the U.S. have a process that requires the submission of a clinical trial application, much like an IND, prior to the commencement of human clinical trials. In the E.U., for example, a CTA must be submitted to the competent national health authority and to independent ethics committees in each country in which a company intends to conduct clinical trials. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed in that country.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical trials must be conducted in accordance with GCP and other applicable regulatory requirements.

To obtain regulatory approval of an investigational drug under E.U. regulatory systems, we must submit a marketing authorization application. This application is similar to the NDA in the U.S., with the exception of, among other things, country-specific document requirements. Drugs can be authorized in the E.U. by using (i) the centralized authorization procedure, (ii) the mutual recognition procedure, (iii) the decentralized procedure or (iv) national authorization procedures.

The EMA implemented the centralized procedure for the approval of human drugs to facilitate marketing authorizations that are valid throughout the E.U. This procedure results in a single marketing authorization granted by the European Commission that is valid across the E.U., as well as in Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for certain human drugs including those that are: (i) derived from biotechnology processes, such as genetic engineering, or (ii) contain a new active substance indicated for the treatment of certain diseases.

Changes in existing laws and regulations affecting the healthcare industry could increase our costs and otherwise adversely affect our business.

Our research and development activities, preclinical studies and clinical trials, and the manufacturing, marketing and labeling of any products we may develop, are subject to extensive regulation by the FDA and other regulatory authorities in the U.S. and other countries. Changes in existing federal, state and foreign laws and agency regulations may be established that could prevent or delay regulatory approval of our drug candidates or materially increase our costs, including:

•

changes in the FDA and foreign regulatory processes for new therapeutics that may delay or prevent the approval of any of our drug candidates;

•

new laws, regulations, or judicial decisions related to healthcare availability or the payment for healthcare products and services, including prescription drugs, that would make it more difficult for us to market and sell products once they are approved by the FDA or foreign regulatory agencies;

•

changes in FDA and foreign regulations that may require additional safety monitoring prior to or after the introduction of new products to market, which could materially increase our costs of doing business; and

•

changes in FDA and foreign current cGMP that would make it more difficult for us to manufacture our drug candidates in accordance with cGMP.

Delays in obtaining or preventing our obtaining regulatory approval of our drug candidates could materially adversely affect our ability to commercialize any of our drug candidates and our ability to receive product revenues or to receive milestone payments or royalties from any product rights we might license to others.

TABLE OF CONTENTS

We rely on independent contractors, including clinical research organizations, in certain areas that are particularly relevant to our research and drug development plans, such as for data management for the conduct of clinical trials. The competition for these relationships is intense, and we may not be able to maintain our relationships with them on acceptable terms. Independent contractors generally may terminate their engagements at any time, subject to notice. As a result, we can control their activities only within certain limits, and they will devote only a certain amount of their time conducting research on and trials of our drug candidates and assisting in developing them. If they do not successfully carry out their duties under their agreements with us, fail to inform us if these trials fail to comply with clinical trial protocols or fail to meet expected deadlines, our clinical trials may need to be extended, delayed or terminated. We may not be able to enter into replacement arrangements without undue delays or excessive expenditures. If there are delays in testing or regulatory approvals as a result of the failure to perform by our independent contractors or other outside parties, our drug candidate development costs will increase and we may not be able to attain regulatory approval for or successfully commercialize our drug candidates.

In addition, we have no control over the financial health of our independent contractors. Several of our independent contractors are in possession of valuable and sensitive information relating to the safety and efficacy of our drug candidates, and several others provide services to a significant percentage of the patients enrolled in our clinical trials in which such independent contractors participate. Should one or more of these independent contractors become insolvent, or otherwise are not able to continue to provide services to us, the clinical trial in which such contractor participates could become significantly delayed and we may be materially adversely affected as a result of the delays and additional expenses associated with such event.

We may not be able to obtain or maintain orphan drug exclusivity for our product candidates.

Prexigebersen has received orphan drug designations for the treatment of AML in the U.S. Orphan designation is available to drugs intended to treat, diagnose or prevent a rare disease or condition that affects fewer than 200,000 people in the U.S. at the time of application for orphan designation. Orphan drug designation must be requested before submitting an application for marketing authorization. Orphan designation qualifies the sponsor of the product for a tax credit and marketing incentives. The first sponsor to receive FDA marketing approval for a drug with an orphan designation is entitled to a seven-year exclusive marketing period in the U.S. for that product for that indication and, typically, a waiver of the prescription drug user fee for its marketing application. However, orphan drug exclusivity may not effectively protect the product candidate from competition for several reasons including different drugs with different active ingredients may be approved for the same condition and competitors also potentially could secure approval of the same drug for different non-orphan conditions. Even after an orphan drug is approved, the FDA can subsequently approve the same drug during the seven-year exclusive marketing period for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. Orphan drug exclusive marketing rights may also be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug.

Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the product candidate any advantage in the regulatory review or approval process. Orphan drug designation in no way ensures ultimate regulatory approval.

In October 2016, prexigebersen also received orphan drug designation for AML in the E.U. from the EMA. To receive orphan drug designation from the EMA, a therapy must be intended for the treatment of a life-threatening or chronically debilitating rare condition with a prevalence of less than five in 10,000 in the E.U. Orphan drug designation provides incentives designed to facilitate development, including fee reductions for protocol assistance, scientific advice and importantly, may provide up to ten years of market exclusivity in the E.U. following product approval.

TABLE OF CONTENTS

There is no guarantee that any of our other drug candidates will receive orphan drug designation or that, even if such drug candidate is granted such status, the drug candidate’s clinical development and regulatory approval process will not be delayed or will be successful.

Risks Related to Manufacturing Our Drug Candidates

We rely on third parties for manufacturing of our clinical drug supplies; our dependence on these manufacturers may impair the development of our drug candidates.

We have no ability to internally manufacture the drug candidates that we need to conduct our clinical trials. For the foreseeable future, we expect to continue to rely on third-party manufacturers and other third parties to produce, package and store sufficient quantities of our drug candidates and any future drug candidates for use in our clinical trials. We have entered into agreements with third-party manufacturers for the manufacture of our drug requirements, including agreements for the manufacture of prexigebersen for use in our Phase 2 clinical trial in AML, as well as agreements for the manufacture of BP1002, BP1003 and BP1001-A for use in our Phase 1 clinical trials. To date, we have made steady progress with our current third-party manufacturers, overcoming challenges associated with scaling up manufacturing to develop their capabilities to supply us with our necessary quantities of drug supplies for our clinical trials. However, we may face various risks and uncertainties in connection with our reliance on third-party manufacturers, including:

•

reliance on third-party manufacturers for regulatory compliance and quality assurance;

•

the possibility of breach of the manufacturing agreement by the third-party manufacturer because of factors beyond our control;

•

the possibility of termination or nonrenewal of our manufacturing agreement by the third-party manufacturer at a time that is costly or inconvenient for us;

•

the potential that third-party manufacturers will develop know-how owned by such third-party manufacturer in connection with the production of our drug candidates that is necessary for the manufacture of our drug candidates; and

•

reliance on third-party manufacturers to assist us in preventing inadvertent disclosure or theft of our proprietary knowledge.

Our drug candidates are complicated and expensive to manufacture. If our third-party manufacturers fail to deliver our drug candidates for clinical use on a timely basis, with sufficient quality, and at commercially reasonable prices, we may be required to delay or suspend clinical trials or otherwise discontinue development of our drug candidates. While we may be able to identify replacement third-party manufacturers or develop our own manufacturing capabilities for these drug candidates, this process would likely cause a delay in the availability of our drug candidates and an increase in costs. In addition, third-party manufacturers may have a limited number of facilities in which our drug candidates can be manufactured, and any interruption of the operation of those facilities due to events such as equipment malfunction or failure or damage to the facility by natural disasters could result in the cancellation of shipments, loss of product in the manufacturing process or a shortfall in available drug candidates.

We may in the future elect to manufacture certain of our drug candidates in our own manufacturing facilities. If we do so, we will require substantial additional funds and need to recruit qualified personnel in order to build or lease and operate any manufacturing facilities.

To date, our drug candidates have been manufactured in relatively small quantities for preclinical testing and clinical trials by third-party manufacturers, and have never been manufactured in large scale. Additionally, as in the development of any new compound, there are underlying risks associated with their manufacture. These risks include, but are not limited to, cost, process scale-up, process reproducibility,

TABLE OF CONTENTS

construction of a suitable process plant, timely availability of raw materials, as well as regulatory issues associated with the manufacture of an active pharmaceutical agent. Any of these risks may prevent us from successfully developing our drug candidates. Our failure, or the failure of our third-party manufacturers to achieve and maintain these high manufacturing standards, including the incidence of manufacturing errors and reliable product packaging for diverse environmental conditions, could result in patient injury or death, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could materially adversely affect our business and financial condition.

If the FDA or other regulatory agencies approve any of our drug candidates for commercial sale, we expect that we would continue to rely, at least initially, on third-party manufacturers to produce commercial quantities of such approved drug candidates. These manufacturers may not be able to successfully increase the manufacturing capacity for any of our approved drug candidates in a timely or economic manner, or at all. Significant scale-up of manufacturing may require additional validation studies, which the FDA or other regulatory authorities must review and approve. If our third-party manufacturers are unable to successfully increase the manufacturing capacity for a drug candidate, or we are unable to establish our own manufacturing capabilities, the commercial launch of any approved products may be delayed or there may be a shortage in supply.

Identification of previously unknown problems with respect to a drug candidate and/or a commercial product(s) with which any of our candidates are being tested or a manufacturer or facility involved in the production of any such candidate or commercial product may result in restrictions on the drug candidate, product, manufacturer or facility that could have a material adverse effect on the development of our drug candidate(s).

The FDA stringently applies regulatory standards for the manufacturing of our drug candidates. Identification of previously unknown problems with respect to a drug candidate, manufacturer or facility may result in restrictions on the drug candidate, manufacturer or facility, including warning letters, suspensions of regulatory approvals, operating restrictions, delays in obtaining new product approvals, withdrawal of the product from the market, product recalls, fines, injunctions and criminal prosecution. Any of the foregoing could have a material adverse effect on our business and financial condition.

In addition, because we are developing at least one of our drug candidates in combination with one or more third-party commercial products, we could also be subject to delays, difficulties, and other adverse effects if any such commercial products (or the companies and/or facilities involved in their marketing and/or production) experience safety, efficacy, compliance, or other issues. For example, one of the therapies with which BP1001 is being studied as a combination therapy candidate may have unexpected safety issues that are improperly attributed to BP1001, or the administration of BP1001 with such other therapies may result in safety issues or adverse events that may not have been present if such other therapies or BP1001 would have been used alone. And, the commercial drug(s) with which any of our candidates is being developed could become unavailable due to any number of circumstances beyond our control. This could delay or prevent our ability to complete the affected clinical studies and/or pursue, obtain, or maintain FDA approval, as applicable.

Our third-party manufacturers are required to produce our drug candidates under FDA cGMP in order to meet acceptable standards for our preclinical testing and clinical trials. If such standards change, the ability of third-party manufacturers to produce our drug candidates on the schedule we require for our preclinical tests and clinical trials may be affected. In addition, third-party manufacturers may not perform their obligations under their agreements with us or may discontinue their business before the time required by us to gain approval for or commercialize our drug candidates. Any difficulties or delays in the manufacturing and supply of our drug candidates could increase our costs or cause us to lose revenue or postpone or cancel clinical trials.

The FDA also requires that we demonstrate structural and functional comparability of a drug candidate produced by different third-party manufacturers. Because we may use multiple sources to manufacture our drug candidates, we may need to conduct comparability studies to assess whether manufacturing changes have affected the safety, identity, purity or potency of any drug candidate compared to the drug candidate

TABLE OF CONTENTS

produced by another manufacturer. If we are unable to demonstrate comparability, the FDA could require us to conduct additional clinical trials, which would be expensive and significantly delay commercialization of our drug candidates.

Risks Related to Commercialization

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our drug candidates, we may not generate product revenue.

We have no commercial products, and we do not currently have an organization for the sales and marketing of pharmaceutical products. In order to successfully commercialize any drug candidates that may be approved in the future by the FDA or comparable foreign regulatory authorities, we must build our sales and marketing capabilities or make arrangements with third parties to perform these services. For certain drug candidates in selected indications where we believe that an approved product could be commercialized by a specialty sales force that calls on a limited but focused group of physicians, we may commercialize these products ourselves. However, in therapeutic indications that require a large sales force selling to a large and diverse prescribing population, we may enter into arrangements with other companies for commercialization. If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, we may not be able to generate product revenue and may not become profitable.

If our future drugs do not achieve market acceptance, we may be unable to generate significant revenue, if any.

Even if our drug candidates obtain regulatory approval, they may not gain market acceptance among physicians, health care payors, patients and the medical community. Factors that we believe could materially affect market acceptance of our drug candidates include:

•

the timing of market introduction of competitive drugs;

•

the demonstrated clinical safety and efficacy of our drug candidates compared to other drugs and other drug candidates;

•

the suitability of our drug candidates to be co-administered or combined with other drugs or drug candidates;

•

the durability of our drug candidates in their ability to prevent the emergence of drug-resistant viral mutants;

•

the convenience and ease of administration of our drug candidates;

•

the existence, prevalence and severity of adverse side effects;

•

other potential advantages of alternative treatment methods;

•

the effectiveness of marketing and distribution support;

•

the cost-effectiveness of our drug candidates; and

•

the availability of reimbursement from managed care plans, the government and other third-party payors.

If our approved drug candidates fail to achieve market acceptance, we would not be able to generate significant revenue. In addition, even if our approved drug candidates achieve market acceptance, we may not be able to maintain that market acceptance over time if:

•

new products or technologies are introduced that are more favorably received than our products, are more cost effective or render our products obsolete;

•

unforeseen complications arise with respect to the use of our products; or

•

sufficient third-party insurance coverage or reimbursement does not remain available.

Even if we receive regulatory approval of any product candidate or therapy that we may develop, we will be subject to ongoing regulatory obligations, reporting requirements and continued regulatory review, which may result in significant additional expenses. If we fail to comply with regulatory requirements or experience unanticipated problems with our products or product candidates, we may be subject to substantial penalties, fines, delays, suspensions, refusals and withdrawals of approvals.

If BP1001 or any other product candidates that we are developing or may in the future are approved, they will be subject to ongoing regulatory requirements and reporting requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, recordkeeping, conduct of post-marketing studies and submission of safety, efficacy and other post-market information, including both federal and state requirements in the U.S. and requirements of comparable non-U.S. regulatory authorities. In addition, we will be subject to continued compliance with cGMP and GCP requirements for any clinical trials that we conduct post-approval.

Facilities of CMOs and testing laboratories are required to comply with extensive FDA, and non-U.S. regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to cGMP, and in certain cases, current Good Tissue Practices (“cGTP”), regulations. As a result, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any NDA, other marketing application, and previous responses to inspection observations. Accordingly, we and others with whom we work with must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

Additionally, the FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses and a company that is found to have improperly promoted off-label uses may be subject to significant liability. The policies of the FDA and of other regulatory authorities may change and additional government regulations maybe enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

The FDA may seek consent decrees or withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with our product candidates, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers, manufacturing processes or testing laboratories, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

•

restrictions on our products, manufacturers or manufacturing processes;

•

warning letters and untitled letters;

•

civil penalties and criminal prosecutions and penalties;

•

fines;

•

injunctions;

•

product seizures or detentions;

•

import or export bans or restrictions;

•

voluntary or mandatory product recalls and related publicity requirements;

•

suspension or withdrawal of regulatory approvals;

TABLE OF CONTENTS

•

total or partial suspension of production; and

•

refusal to approve pending applications for marketing approval of new products or of supplements to approved applications.

If third-party payors do not adequately reimburse patients for any of our drug candidates that are approved for marketing, they might not be purchased or used, and our revenues and profits will not develop or increase.

Our revenues and profits will depend significantly upon the availability of adequate reimbursement for the use of any approved drug candidates from governmental and other third-party payors, both in the U.S. and in foreign markets. Reimbursement by a third party may depend upon a number of factors, including the third-party payor’s determination that use of an approved drug candidate is:

•

a covered benefit under its health plan;

•

safe, effective and medically necessary;

•

appropriate for the specific patient;

•

cost effective; and

•

neither experimental nor investigational.

The regulations that govern marketing approvals, pricing and reimbursement for new therapeutic and diagnostic products vary widely from country to country. Some countries require approval of the sale price of a drug candidate before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for a drug candidate in a particular country, but then be subject to price regulations that delay our commercial launch of the approved drug and negatively impact the revenues we are able to generate from the sale of the approved drug in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more drug candidates, even if our drug candidates obtain regulatory approval.

Obtaining reimbursement approval for an approved drug from each third-party and government payor is a time-consuming and costly process that could require us to provide supporting scientific, clinical and cost-effectiveness data for the use of any approved drug candidates to each payor. We may not be able to provide data sufficient to gain acceptance with respect to reimbursement. There also exists substantial uncertainty concerning third-party reimbursement for the use of any approved drug incorporating new technology, and even if determined eligible, coverage may be more limited than the purposes for which the drug is approved by the FDA. Moreover, eligibility for coverage does not imply that any approved drug will be reimbursed in all cases or at a rate that allows us to make a profit or even cover our costs. Interim payments for new products, if applicable, may also be insufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the approved drugs and the clinical setting in which it is used, may be based on payments allowed for lower-cost products or combinations of products that are already reimbursed, may be incorporated into existing payments for other products or services, and may reflect budgetary constraints and/or imperfections in Medicare or Medicaid data used to calculate these rates. Net prices for products may be reduced by mandatory discounts or rebates required by government health care programs or by any future relaxation of laws that restrict imports of certain medical products from countries where they may be sold at lower prices than in the U.S.

In the U.S., at both the federal and state levels, the government regularly proposes legislation to reform health care and its cost, and such proposals have received increasing political attention. While health care reform may increase the number of patients who have insurance coverage for the use of any approved drug, it may also include changes that adversely affect reimbursement for approved drugs. In addition, there has been, and we expect that there will continue to be, federal and state proposals to constrain expenditures for medical products and services, which may affect payments for any of our drug candidates that obtain approval. The Centers for Medicare and Medicaid Services frequently change product descriptors, coverage policies, product and service codes, payment methodologies and reimbursement values. Third-party payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates and may have

TABLE OF CONTENTS

sufficient market power to demand significant price reductions. As a result of actions by these third-party payors, the health care industry is experiencing a trend toward containing or reducing costs through various means, including lowering reimbursement rates, limiting therapeutic class coverage and negotiating reduced payment schedules with service providers for drug products.

Our inability to promptly obtain coverage and profitable reimbursement rates from government-funded and private payors for any of our drug candidates that obtain approval could have a material adverse effect on our business and financial condition.

Risks Related to Intellectual Property

If our patent position does not adequately protect our drug candidates, others could compete against us more directly, which would harm our business.

Our patent portfolio currently includes seven issued patents in the U.S. and sixty-one issued patents in foreign jurisdictions. We have three additional pending patent applications in the U.S. and five additional allowed patent application in a foreign jurisdiction. Further, we have pending patent applications in key foreign jurisdictions across our six families of applications. Our success depends in large part on our ability to obtain and maintain patent protection both in the U.S. and in other countries for our drug candidates. Our ability to protect our drug candidates from unauthorized or infringing use by third parties depends in substantial part on our ability to obtain and maintain valid and enforceable patents. Due to evolving legal standards relating to the patentability, validity and enforceability of patents covering pharmaceutical inventions and the scope of claims made under these patents, our ability to maintain, obtain and enforce patents is uncertain and involves complex legal and factual questions. Accordingly, rights under any issued patents may not provide us with sufficient protection for our drug candidates or provide sufficient protection to afford us a commercial advantage against competitive products or processes. We cannot guarantee that any patents will issue from any pending or future patent applications owned by or licensed to us.

Even if patents have issued or will issue, we cannot guarantee that the claims of these patents are or will be valid or enforceable or will provide us with any significant protection against competitive products or otherwise be commercially valuable to us. Patent applications in the U.S. are maintained in confidence for up to 18 months after their filing. In some cases, however, patent applications remain confidential in the USPTO for the entire time prior to issuance as a U.S. patent. Similarly, publication of discoveries in the scientific or patent literature often lags behind actual discoveries. Consequently, we cannot be certain that we or our licensors were the first to invent, or the first to file patent applications on, our drug candidates. The costs of these proceedings could be substantial and it is possible that our efforts would be unsuccessful, resulting in a loss of our U.S. patent position. Furthermore, we may not have identified all U.S. and foreign patents or published applications that affect our business either by blocking our ability to commercialize our drugs or by covering similar technologies that affect our drug market.

The claims of any patents which may issue in the future and be owned by or licensed to us, may not confer on us significant commercial protection against competing products. Additionally, our patents may be challenged by third parties, resulting in the patent being deemed invalid, unenforceable or narrowed in scope, or the third party may circumvent any such issued patents. Our patents might not contain claims that are sufficiently broad to prevent others from utilizing our technologies. Consequently, our competitors may independently develop competing products that do not infringe our patents or other intellectual property. To the extent a competitor can develop similar products using a different molecule, our patents may not prevent others from directly competing with us.

The laws of some foreign jurisdictions do not protect intellectual property rights to the same extent as in the U.S. and many companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such difficulties in protecting or are otherwise precluded from effectively protecting our intellectual property rights in foreign jurisdictions, our business prospects could be substantially harmed.

Because of the extensive time required for development, testing and regulatory review of a drug candidate, it is possible that, before any of our drug candidates can be commercialized, any related patent may expire or remain in force for only a short period following commercialization of our drug candidates,

TABLE OF CONTENTS

thereby reducing any advantages of the patent. To the extent our drug candidates based on that technology are not commercialized significantly ahead of the date of any applicable patent, or to the extent we have no other patent protection on such drug candidates, those drug candidates would not be protected by patents, and we would then rely solely on other forms of exclusivity, such as regulatory exclusivity provided by the FDCA or trade secret protection.

The Leahy-Smith America Invents Act (the “America Invents Act”) was signed into law in September 2011, and many of the substantive changes became effective in March 2013. The America Invents Act reforms U.S. patent law in part by changing the standard for patent approval from a “first to invent” standard to a “first to file” standard and developing a post-grant review system. This legislation changes U.S. patent law in a way that may weaken our ability to obtain patent protection in the U.S. for those applications filed after March 2013.

If any third-party owners of intellectual property we may license in the future do not properly maintain or enforce the patents underlying such licenses, our competitive position and business prospects will be harmed.

We may enter into licenses for third-party intellectual property in the future. Our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for their intellectual property, in particular, those patents to which we have secured exclusive rights. If applicable, our licensors may not successfully prosecute the patent applications to which we are licensed. Even if patents issue in respect of any such patent applications, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue such litigation less aggressively than we would. In addition, our licensors may terminate their agreements with us in the event we breach the applicable license agreement and fail to cure the breach within a specified period of time. Without protection for the intellectual property we license, other companies might be able to offer substantially identical products for sale, which could materially adversely affect our competitive business position, business prospects and financial condition.

Because our research and development of drug candidates incorporates compounds and other information that is the intellectual property of third parties, we depend on continued access to such intellectual property to conduct and complete our preclinical and clinical research and commercialize the drug candidates that result from this research. We expect that future licenses would impose, numerous obligations on us. For example, under our future license agreements, we may be required to pay (i) annual maintenance fees until a drug candidate is sold for the first time, (ii) running royalties on net sales of drug candidates, (iii) minimum annual royalties after a drug candidate is sold for the first time, and (iv) one-time payments upon the achievement of specified milestones. We may also be required to reimburse patent costs incurred by the licensor, or we may be obligated to pay additional royalties, at specified rates, based on net sales of our drug candidates that incorporate the licensed intellectual property rights. We may also be obligated under some of these agreements to pay a percentage of any future sublicensing revenues that we may receive. Future license agreements may also include payment obligations such as milestone payments or minimum expenditures for research and development. We expect that any future licenses would contain reporting, insurance and indemnification requirements.

If we infringe or are alleged to infringe intellectual property rights of third parties, our business could be harmed.

Our research, development and commercialization activities, including any drug candidates resulting from these activities, may infringe or be claimed to infringe patents or other proprietary rights owned by third parties and to which we do not hold licenses or other rights. There may be applications that have been filed but not published that, if issued, could be asserted against us. If a patent infringement suit were brought against us, we could be forced to stop or delay research, development or manufacturing of drug candidate that is the subject of the suit. Further, if we are found to have infringed a third- party patent, we could be obligated to pay royalties and/or other payments to the third party related to our drug candidates, which may be substantial, or we could be enjoined from selling our drug candidates that obtain approval.

There has been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical and biotechnology industries. In addition to infringement claims against us, we may become a party to other patent litigation and other proceedings, including interference

TABLE OF CONTENTS

proceedings declared by the USPTO and opposition proceedings in the European Patent Office, regarding intellectual property rights with respect to our drug candidates and technology. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our business and financial condition.

Litigation regarding patents, intellectual property and other proprietary rights may be expensive and time consuming. If we are involved in such litigation, it could cause delays in bringing drug candidates to market and harm our ability to operate.

Our success will depend in part on our ability to operate without infringing the proprietary rights of third parties. Although we are not currently aware of any litigation or other proceedings or third-party claims of intellectual property infringement related to our drug candidates, the pharmaceutical industry is characterized by extensive litigation regarding patents and other intellectual property rights. Other parties may obtain patents in the future and allege that the use of our technologies infringes these patent claims or that we are employing their proprietary technology without authorization. Likewise, third parties may challenge or infringe upon our existing or future patents. Proceedings involving our patents or patent applications or those of others could result in adverse decisions regarding:

•

the patentability of our inventions relating to our drug candidates; and/or

•

the enforceability, validity or scope of protection offered by our patents relating to our drug candidates.

Even if we are successful in these proceedings, we may incur substantial costs and divert management time and attention in pursuing these proceedings, which could have a material adverse effect on us. If we are unable to avoid infringing the patent rights of others, we may be required to seek a license, defend an infringement action or challenge the validity of the patents in court. Patent litigation is costly and time consuming. We may not have sufficient resources to bring these actions to a successful conclusion. In addition, if we do not obtain a license, develop or obtain non-infringing technology, fail to defend an infringement action successfully or have infringed patents declared invalid, we may:

•

incur substantial monetary damages;

•

encounter significant delays in bringing our drug candidates to market; and/or

•

be precluded from participating in the manufacture, use or sale of our drug candidates or methods of treatment requiring licenses.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If investors perceive these results to be negative, the market price for our common stock could be significantly harmed.

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information and may not adequately protect our intellectual property.

We rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. In order to protect our proprietary technology and processes, we also rely in part on confidentiality and intellectual property assignment agreements with our corporate partners, employees, consultants, outside scientific collaborators and sponsored researchers and other advisors. These agreements may not effectively prevent disclosure of confidential information nor result in the effective assignment to us of intellectual property, and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information or other breaches of the agreements. In addition, others may independently discover our trade secrets and proprietary information, and in such case we could not assert any trade secret rights against such party. Enforcing a claim that a party illegally obtained and is using our trade secrets is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the U.S. may be less willing to protect trade secrets. Costly and time-consuming litigation could be necessary to seek to enforce and determine the scope

TABLE OF CONTENTS

of our proprietary rights, and failure to obtain or maintain trade secret protection could materially adversely affect our business and financial condition.

We may be subject to claims that our employees and contractors have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industries, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees, or we, have used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Risks Related to Our Securities

We expect to seek the additional capital necessary to fund our operations through public or private equity offerings, collaboration agreements, debt financings or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, existing stockholders’ ownership interests will be diluted and the terms may include liquidation or other preferences that adversely affect their rights as a stockholder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or drug candidates, or grant licenses on terms that are not favorable to us. In addition, sales of a substantial number of shares of our common stock or other securities in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock.

As of January 15, 2025, there were 96,389 shares of common stock reserved for issuance upon the exercise of outstanding options granted under our equity incentive plans. As of January 15, 2025, there were (i) 937 additional shares of common stock reserved for future issuance of awards under the Bio-Path Holdings, Inc. 2017 Stock Incentive Plan, as amended (the “2017 Stock Incentive Plan”), and (ii) 1,200,948 additional shares of common stock reserved for future issuance of awards under the Bio-Path Holdings, Inc. 2022 Stock Incentive Plan (the “2022 Stock Incentive Plan”). In addition, as of January 15, 2025, there were 16,490,014 shares of common stock reserved for issuance upon the exercise of outstanding warrants that we have issued in connection with prior securities offerings. To the extent that outstanding stock options and warrants are exercised, existing stockholders’ ownership interests may be diluted, which may reduce the market price of our common stock.

The trading price of our common stock has been volatile and is likely to be volatile in the future.

The trading price of our common stock has been highly volatile. From January 1, 2020 through January 15, 2025, our stock price has fluctuated from a low of $0.61 to a high of $486.80, after adjustment for reverse stock splits. The market price for our common stock will be affected by a number of factors, including:

•

the denial or delay of regulatory approvals of our drug candidates or receipt of regulatory approval of competing products;

•

our ability to accomplish clinical, regulatory and other drug development milestones;

TABLE OF CONTENTS

•

the ability of our drug candidates, if they receive regulatory approval, to achieve market success;

•

the performance of third-party manufacturers and suppliers;

•

developments with respect to patents and other intellectual property rights;

•

sales of common stock or other securities by us or our stockholders in the future;

•

additions or departures of key scientific or management personnel;

•

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our drug candidates;

•

trading volume of our common stock;

•

investor perceptions about us and our industry;

•

public reaction to our press releases, other public announcements and SEC and other filings;

•

the failure of analysts to cover us, or changes in analysts’ estimates or recommendations;

•

the failure by us to meet analysts’ projections or guidance;

•

general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors; and

•

the other factors described elsewhere in this “Item 1A. Risk Factors” or the section titled “Risk Factors” contained in our other public filings.

The stock prices of many companies in the biotechnology industry have experienced wide fluctuations that have often been unrelated to the operating performance of these companies. Following periods of volatility in the market price of a company’s securities, securities class action litigation often has been initiated against a company. If any class action litigation is initiated against us, we may incur substantial costs and our management’s attention may be diverted from our operations, which could materially adversely affect our business and financial condition.

To date, we have a low volume of daily trades in our common stock on The Nasdaq Capital Market. Our stockholders may be unable to sell their common stock at or near their asking prices or at all, which may result in substantial losses to our stockholders.

The market for our common stock may be characterized by significant price volatility when compared to seasoned issuers, and we expect that our share price will be more volatile than a seasoned issuer for the foreseeable future. As noted above, our common stock may be sporadically and/or thinly traded. As a consequence of this lack of liquidity, the trading of relatively small quantities of shares by our stockholders may disproportionately influence the price of those shares in either direction.

Our certificate of incorporation grants our Board of Directors the power to designate and issue additional shares of common and/or preferred stock.

Our authorized capital consists of 200,000,000 shares of common stock and 10,000,000 shares of preferred stock. Our preferred stock may be designated into series pursuant to authority granted by our certificate of incorporation, and on approval from our Board of Directors (the “Board”). The Board, without any action by our stockholders, may designate and issue shares in such classes or series as the Board deems appropriate and establish the rights, preferences and privileges of such shares, including dividends, liquidation and voting rights. The rights of holders of other classes or series of stock that may be issued could be superior to the rights of holders of our common shares. The designation and issuance of shares of capital stock having preferential rights could adversely affect other rights appurtenant to shares of our common stock.

TABLE OF CONTENTS

We do not anticipate paying cash dividends, and accordingly stockholders must rely on stock appreciation for any return on their investment in us.

We anticipate that we will retain our earnings, if any, for future growth and therefore do not anticipate paying cash dividends in the future. As a result, only appreciation of the price of our common stock will provide a return to stockholders.

Our management is required to devote substantial time and incur additional expense to comply with public company regulations.

As a public reporting company, we are subject to the Sarbanes-Oxley Act of 2002, as well as to the information and reporting requirements of the SEC and other federal securities laws. We are also subject to the rules of The Nasdaq Stock Market. As a result, we incur significant legal, accounting, and other expenses that we would not incur as a private company, including costs associated with our public company reporting requirements and corporate governance requirements. Compliance with these public company obligations places significant additional demands on our limited number of finance and accounting staff and on our financial, accounting and information systems.

Failure to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002 could have a material adverse effect on the price of our common stock.

Section 404 of the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the SEC require an annual management assessment of the effectiveness of our internal control over financial reporting. As a smaller reporting company as defined in Rule 12b-2 under the Exchange Act, we are currently exempt from the auditor attestation requirement of Section 404(b). If we lose this eligibility, we will incur increased personnel and audit fees in connection with the additional audit requirements. If we fail to maintain the adequacy of our internal control over financial reporting, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002 and the related rules and regulations of the SEC. If we cannot in the future favorably assess the effectiveness of our internal control over financial reporting, investor confidence in the reliability of our financial reports may be adversely affected, which could have a material adverse effect on the price of our common stock.

Recent and future reverse stock splits may decrease the liquidity of our common stock and result in higher transaction costs.

Our stockholders approved a reverse stock split at our 2024 Annual Meeting which may be effected in the sole discretion of the Board of Directors, at a ratio of up to 1-for-30, and may be abandoned in the sole discretion of the Board of Directors. The liquidity of our common stock may be negatively impacted by any such reverse stock split, given the reduced number of shares that are outstanding after such a reverse stock split, particularly if the stock price does not increase as a result of such reverse stock split. Additionally, if the reverse stock split is implemented, it will increase the number of our stockholders who own “odd lots” of fewer than 100 shares of common stock. Brokerage commissions and other costs of transactions in odd lots are generally higher than the costs of transactions of more than 100 shares of common stock. Accordingly, a reverse stock split may not achieve the desired results of increasing the stock price of our common stock.

Following a reverse stock split, the resulting market price of our common stock may not attract new investors, including institutional investors, and may not satisfy the investing requirements of those investors. Consequently, the trading liquidity of our common stock may not improve.

Although we believe that a higher market price of our common stock may help generate greater or broader investor interest, there can be no assurance that a reverse stock split, will result in a share price that will attract new investors, including institutional investors. In addition, there can be no assurance that the market price of our common stock will satisfy the investing requirements of those investors. As a result, the trading liquidity of our common stock may not necessarily improve. If we effect the reverse stock split approved at the 2024 Annual Meeting, the primary intent will be the anticipated increase in the price of our common stock immediately following and resulting from a reverse stock split due to the reduction in the number of issued and outstanding shares of common stock would help us meet the Minimum Bid Price Rule

TABLE OF CONTENTS

pursuant to Nasdaq Listing Rules. It cannot be assured that a reverse stock split will result in any sustained proportionate increase in the market price of our common stock, which is dependent upon many factors, including our business and financial performance, general market conditions, and prospects for future success, which are unrelated to the number of shares of our common stock outstanding. It is not uncommon for the market price of a company’s common stock to decline in the period following a reverse stock split.

If securities or industry analysts do not publish research or reports about us, or if they adversely change their recommendations regarding our common stock, then our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us, our industry and our market. If no analyst elects to cover us and publish research or reports about us, the market for our common stock could be severely limited and our stock price could be adversely affected. As a small-cap company, we are more likely than our larger competitors to lack coverage from securities analysts. In addition, even if we receive analyst coverage, if one or more analysts ceases coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. If one or more analysts who elect to cover us issue negative reports or adversely change their recommendations regarding our common stock, our stock price could decline.

USE OF PROCEEDS

We expect to receive net proceeds from this offering of approximately $8.9 million, based on an assumed combined public offering price of $0.769 per share of common stock and accompanying Common Warrants, which is the last reported sale price per share of our common stock on the Nasdaq Capital Market on February 11, 2025, after deducting estimated placement agent fees and the estimated offering expenses payable by us, assuming no sale of any Pre-Funded Warrants in this offering and excluding the proceeds we may receive from the cash exercise of the Common Warrants issued in this offering, if any. We cannot predict when or if the Pre-Funded Warrants, the Common Warrants and the Placement Agent Warrants will be exercised, or if they will be exercised for cash. It is possible that the Common Warrants and the Placement Agent Warrants may expire and may never be exercised. Because this is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, Placement Agent’s fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes. As of the date of this prospectus, we cannot specify with certainty all of the particular uses of the proceeds from this offering. Accordingly, we will retain broad discretion over the use of such proceeds.

TABLE OF CONTENTS

DILUTION

If you invest in our securities, you will experience immediate and substantial dilution to the extent of the difference between the effective public offering price per share of common stock in this offering and the pro forma as adjusted net tangible book value per share of our common stock immediately after the offering.

Our net tangible book value per share is determined by subtracting our total liabilities from our total tangible assets, which is total assets less intangible assets, and dividing this amount by the number of shares of common stock outstanding. The historical net tangible book value of our common stock as of September 30, 2024 was approximately $(0.4) million, or $(0.11) per share, based on 3,710,190 shares of our common stock outstanding at September 30, 2024.

After giving effect to the Warrant Exercises and the receipt of net proceeds by us of $2,058 and the net proceeds received in the October 2024 Private Placement, the pro forma net tangible book value of our common stock as of September 30, 2024 would have been approximately $3.5 million, or $0.60 per share, based on 5,767,892 shares of our common stock outstanding.

After giving further effect to the sale of shares of common stock and accompanying Common Warrants to be sold in this offering (assuming no sale of any Pre-Funded Warrants), at the assumed combined public offering price of $0.769 per share of common stock and accompanying Common Warrant, which is the last reported sale price per share of our common stock on the Nasdaq Capital Market on February 11, 2025, and after deducting the estimated placement agent fees and the estimated offering expenses payable by us, and excluding the proceeds we may receive from the exercise of the Common Warrants issued in this offering, our pro forma as adjusted net tangible book value as of September 30, 2024 would have been approximately $12.4 million, or $0.66 per share of common stock. This represents an immediate increase in pro forma as adjusted net tangible book value of $0.06 per share to existing stockholders and an immediate dilution of $0.11 per share to new investors in this offering. The following table illustrates this dilution on a per share basis:

Assumed combined public offering price per share and Common Warrants			$	0.769
Historical net tangible book value per share as of September 30, 2024	$	(0.11)
Pro forma net tangible book value after giving effect to the Warrant Exercises and the October 2024 Private Placement	$	0.60
Increase in net tangible book value per share attributable to new investors	$	0.06
Pro forma as adjusted net tangible book value per share as of September 30, 2024, after this offering			$	0.66
Dilution per share to new investors			$	0.11

A $0.20 increase in the assumed combined public offering price of $0.769 per share and Common Warrants would increase our pro forma as adjusted net tangible book value after this offering to $15.0 million, or $0.80 per share, and the dilution per share to investors purchasing securities in this offering would be approximately $0.17 per share, assuming that the number of shares of common stock and Common Warrants offered by us, as set forth on the cover page of this prospectus, remains the same (assuming no sale of Pre-Funded Warrants) and after deducting the estimated placement agent fees and estimated offering expenses payable by us. Similarly, a $0.20 decrease in the assumed combined public offering price of $0.769 per share and Common Warrants would increase our pro forma as adjusted net tangible book value after this offering to $9.8 million, or $0.52 per share, and the dilution per share to investors purchasing securities in this offering would be approximately $0.05 per share, assuming that the number of shares of common stock and Common Warrants offered by us, as set forth on the cover page of this prospectus remains the same (assuming no sale of Pre-Funded Warrants) and after deducting the estimated placement agent fees and estimated offering expenses payable by us.

An increase of one million shares of common stock and accompanying Common Warrants offered by us from the assumed number of shares of common stock and accompanying Common Warrants set forth on the cover page of this prospectus would increase our pro forma as adjusted net tangible book value after this offering to $13.1 million, or $0.66 per share, and the dilution per share to investors purchasing securities

TABLE OF CONTENTS

in this offering would be approximately $0.11 per share, assuming that the assumed combined public offering price remains the same and after deducting the estimated placement agent fees and estimated offering expenses payable by us. Similarly, a decrease of one million shares of common stock and accompanying Common Warrants offered by us from the assumed number of shares of common stock and accompanying Common Warrants set forth on the cover page of this prospectus would increase our pro forma as adjusted net tangible book value after this offering to $11.6 million, or $0.65 per share, and the dilution per share to investors purchasing securities in this offering would be approximately $0.12 per share, assuming that the assumed combined public offering price remains the same and after deducting the estimated placement agent fees and estimated offering expenses payable by us.

The information discussed above is for illustration only and will adjust based on the actual public offering price, the actual number of shares and Common Warrants that we offer in this offering and other terms of this offering determined at pricing. The discussion and table above assume (i) no sale of Pre-Funded Warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis and (ii) no exercise of Common Warrants accompanying the shares of common stock sold in this offering.

The above discussion and table are based on 3,710,190 shares of our common stock outstanding as of September 30, 2024, which excludes as of September 30, 2024:

•

96,389 shares of common stock reserved for issuance upon the exercise of outstanding options granted under our equity incentive plans with a weighted average exercise price of $71.40 per share;

•

1,200,948 additional shares of common stock reserved for future issuance under our 2022 Stock Incentive Plan; and

•

4,421,679 shares of common stock that may be issued upon exercise of outstanding warrants with a weighted average exercise price of $3.13 per share.

Except with respect to the Warrant Exercises, the above illustration of dilution per share to investors participating in this offering does not take into account further dilution to investors in this offering that could occur upon the exercise of outstanding options and warrants having a per share exercise price less than the effective public offering price per share in this offering. To the extent that any of these outstanding options or warrants outstanding as of September 30, 2024, have been or are exercised in the future or we issue additional shares under our equity incentive plans, investors purchasing securities in this offering may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

In addition to historical information, this prospectus contains forward-looking statements that involve significant risks and uncertainties, which may cause our actual results to differ materially from plans and results discussed in forward-looking statements. We encourage you to review the risks and uncertainties, discussed in “Risk Factors” and “Special Note Regarding Forward-Looking Statements,” included elsewhere in this prospectus. The risks and uncertainties can cause actual results to differ significantly from those forecasted in forward-looking statements or implied in historical results and trends.

The following discussion of our financial condition and results of operations should be read in conjunction with our financial statements and related notes included elsewhere in this prospectus.

Overview

We are a clinical and preclinical stage oncology-and obesity-focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target-specific protein inhibition for any gene product that is over-expressed in disease. Our drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a lipid bilayer having neutral charge. We believe this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. Through testing in numerous animal studies and dosing in clinical trials, our DNAbilize® drug candidates have demonstrated an excellent safety profile. DNAbilize® is a registered trademark of the Company.

Using DNAbilize® as a platform for drug development and manufacturing, we currently have four drug candidates in development to treat at least five different cancer disease indications. Our lead drug candidate, BP1001, or “prexigebersen,” which is being developed to target Grb2, initially started the efficacy portion of a Phase 2 clinical trial for untreated AML patients in combination with LDAC. However, the changing landscape of AML treatment has led to amendment of the Phase 2 clinical study by removing the combination treatment of prexigebersen and LDAC and replacing it with the combination treatment of prexigebersen and decitabine.

Venetoclax in combination with LDAC, decitabine or azacytidine (the latter two drugs are DNA hypomethylating agents) is approved as frontline therapy for newly diagnosed AML in adults who are 75 years or older, or who have comorbidities precluding intensive induction chemotherapy. We believe this approval of the frontline venetoclax and decitabine combination therapy provides an opportunity for developing prexigebersen as an addition to the combination therapy for the treatment of newly diagnosed AML patients. In preclinical efficacy studies, four AML cancer cell lines were treated with three different combinations of decitabine, venetoclax and prexigebersen. Decrease in AML cell viability was the primary measure of efficacy. The triple combination of decitabine, venetoclax and prexigebersen showed significant improvement in efficacy in three of the four AML cell lines. Based on these results, we believe that adding prexigebersen to the treatment combination of decitabine and venetoclax could lead to improved efficacy in AML patients.

TABLE OF CONTENTS

anticipated to be conducted at up to ten clinical sites in the U.S., and Gail J. Roboz, MD, is the national coordinating Principal Investigator for the Phase 2 trial. Dr. Roboz is a professor of medicine and director of the Clinical and Translational Leukemia Program at the Weill Medical College of Cornell University (the “Weill Medical College”) and the New York-Presbyterian Hospital in New York City.

On June 3, 2024, we announced additional interim data for the first two cohorts of the Phase 2 clinical trial. In Cohort 1, 31 newly diagnosed patients were enrolled; 20 evaluable patients with a median age of 75 years, treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk or secondary AML evolved from myelodysplastic syndromes, chronic myelomonocytic leukemia or treatment-related AML. Fifteen patients (75%) achieved CR/CRi/CRh. One patient achieved partial remission (“PR”), three patients achieved stable disease, and one patient had toxicity attributed to decitabine and venetoclax treatment. In Cohort 2, 40 relapsed/refractory patients were enrolled; 23 evaluable patients with a median age of 63 years, treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk or secondary AML. Twelve patients (55%) achieved CR/CRi/CRh, one patient achieved PR, eight patients achieved stable disease and two patients had progressive disease or treatment failure. Among the evaluable patients of both cohorts, adverse events were consistent with those expected with decitabine and venetoclax and/or AML, including fatigue (72%), anemia (60%) and neutropenia (49%), while the most frequent severe adverse events were febrile neutropenia (26%) and sepsis (5%). The interim analysis data was selected as an oral presentation in the 2024 ASCO Annual Meeting and as a poster presentation in the 2024 EHA Annual Meeting. Based on this interim data, we expect to continue enrollment of up to 98 and 54 evaluable patients for Cohorts 1 and 2, respectively and plan to pursue FDA expedited programs for Fast Track designation. We are evaluating whether to seek to expand Stage 2 of the Phase 2 clinical trial in Europe. We expect to complete enrollment in cohorts 1 and 2 in 2026.

Our second drug candidate, Liposomal Bcl-2 (“BP1002”), targets the protein Bcl-2, which is responsible for driving cell survival in up to 60% of all cancers. A Phase 1 clinical trial to evaluate the ability of BP1002 to treat refractory/relapsed lymphoma and refractory/relapsed CLL patients is being conducted at the Georgia Cancer Center, The University of Texas Southwestern and New York Medical College. A total of six evaluable patients are scheduled to be treated over two dose levels with BP1002 monotherapy in a standard 3+3 design. Enrollment has been successfully completed for both dose cohorts, 20 and 40 mg/m2. There were no dose limiting toxicities.

Additionally, preclinical studies suggest that the combination of BP1002 with decitabine is efficacious in venetoclax-resistant cells. An abstract of the preclinical study was presented at the 2021 American Association for Cancer Research (“AACR”) Annual Meeting. A Phase 1/1b clinical trial to investigate the ability of BP1002 to treat refractory/relapsed AML patients, including venetoclax-resistant patients, is being studied. A recent study found that AML patients who had relapsed from frontline venetoclax-based treatment had a very poor prognosis, with a median survival of less than three months. Since venetoclax and BP1002 utilize different mechanisms of action, we believe that BP1002 may be a potential treatment for venetoclax-relapsed AML patients. The Phase 1/1b clinical trial is being conducted at several leading cancer centers in the United States, including the Weill Medical College, MD Anderson, Scripps Health and The University of California at Los Angeles Cancer Center. On October 7, 2024, we announced that the FDA had completed its review of PK/PD data from the first two dosing cohorts (20 and 40 mg/m2) and that the enrollment for the third dosing cohort (60 mg/m2) is now complete. We expect to advance to the next planned higher dose of 90 mg/m2 in the fourth quarter of 2024. The approved treatment cycle is two doses per week over four weeks, resulting in eight doses administered over twenty-eight days. The Phase 1b portion of the study is expected to commence after completion of BP1002 monotherapy cohorts and will assess the safety and efficacy of BP1002 in combination with decitabine in refractory/relapsed AML patients.

TABLE OF CONTENTS

Our third drug candidate, Liposomal STAT3 (“BP1003”), targets the STAT3 protein and is currently in IND enabling studies as a potential treatment of pancreatic cancer, NSCLC and AML. Preclinical studies showing BP1003’s ability to inhibit STAT3 protein expression and cancer cell viability had been presented at AACR Annual Meetings. On September 16, 2024, we announced a publication in the peer-reviewed journal, Biomedicines, which highlights the therapeutic potential and broad anti-tumor effect of BP1003 in numerous preclinical solid tumor models, including breast, ovarian, and pancreatic cancer. The lead indication for which we intend to develop BP1003 is pancreatic cancer due to the severity of this disease and the lack of effective, life-extending treatments. For example, pancreatic adenocarcinoma is projected to be the second most lethal cancer behind lung cancer by 2030. Typical survival for a metastatic pancreatic cancer patient is about three to six months from diagnosis. We have successfully completed several IND enabling studies of BP1003 and have one additional IND enabling study to complete. Once the additional study is successfully completed, our goal is to file an IND application and initiate the first-in-humans Phase 1 study of BP1003 in patients with refractory, metastatic solid tumors, including pancreatic cancer and NSCLC.

In addition, a modified product named BP1001-A, our fourth drug candidate, has shown to enhance chemotherapy efficacy in a preclinical study involving solid tumor models. Results of the preclinical study were published in the scientific journal Oncotarget in 2020. BP1001-A incorporates the same drug substance as prexigebersen but has a slightly modified formulation designed to enhance nanoparticle properties. A BP1001-A Phase 1/1b clinical trial in patients with advanced or recurrent solid tumors is being conducted at several leading cancer centers in the United States, including MD Anderson, Karmanos Cancer Institute, Mary Crowley Cancer Research and Holy Cross Hospital, Maryland. A total of nine evaluable patients are scheduled to be treated with BP1001-A monotherapy over three dose levels in a standard 3+3 dose escalation design. The first dose cohort consisted of a starting dose of 60 mg/m2 had been completed, and there were no dose limiting toxicities. Enrollment is now open for patients for the second dose cohort of 90 mg/m2 which we expect to be complete in the first quarter of 2025 in order to advance to dose level 3. The Phase 1b portion of the study is expected to commence after successful completion of BP1001-A monotherapy cohorts and is intended to assess the safety and efficacy of BP1001-A in combination with paclitaxel in patients with recurrent ovarian or endometrial tumors. Phase 1b studies are also expected to be opened in combination with gemcitabine in Stage 4 pancreatic cancer and combination therapy in breast cancer.

Development and Treatment for Obesity

Insulin resistance is a major contributor to obesity, Type 2 diabetes and other related metabolic diseases. Insulin lowers blood glucose level by activating the PI3K/AKT pathway. However, this insulin pathway is dysfunctional in obese patients who have Type 2 diabetes. Literature suggests that Grb2 is an inhibitor of the insulin/PI3K/AKT pathway. Upregulation of the Grb2 gene has been reported for patients with Type 2 diabetes. Knockdown of Grb2 expression enhanced insulin-induced AKT activity and glucose uptake in myoblast and hepatoma cells. Furthermore, insulin sensitivity was restored in Grb2 heterozygous knockout mice fed on high fat-induced diet. We are currently exploring the development of BP1001-A as a drug candidate to target insulin resistance. We hypothesize that by downregulating Grb2 expression, BP1001-A could potentially lower blood glucose level by enhancing insulin-mediated AKT activation and glucose uptake and storage and intend to pursue further studies to test such hypothesis.

TABLE OF CONTENTS

opinion leaders in the field of study and include developing drug candidates for diseases other than cancer. As we expand our drug development programs, we will look at indications where a systemic delivery is needed and antisense RNAi nanoparticles can be used to slow, reverse or cure a disease, either alone or in combination with another drug.

We have certain intellectual property as the basis for our current drug products in clinical development, prexigebersen, BP1002, BP1003 and BP1001-A. We are developing RNAi antisense nanoparticle drug candidates based on our own patented technology to treat cancer, obesity and autoimmune disorders where targeting a single protein may be advantageous and result in reduced patient adverse effects as compared to small molecule inhibitors with off-target and non-specific effects. We have composition of matter and method of use intellectual property for the design and manufacture of antisense RNAi nanoparticle drug products.

As of September 30 2024, we had an accumulated deficit of $114.7 million. Our net loss was $16.1 million and $7.1 million for the year ended December 31, 2023 and for nine months ended September 30, 2024, respectively. We expect to continue to incur significant operating losses, and we anticipate that our losses may increase substantially as we expand our drug development programs and commercialization efforts. To achieve profitability, we must enter into license or development agreements with third parties or successfully develop and obtain regulatory approval for one or more of our drug candidates and effectively commercialize any drug candidates we develop. In addition, if we obtain regulatory approval of one or more of our drug candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Even if we succeed in developing and commercializing one or more of our drug candidates, we may not be able to generate sufficient revenue and we may never be able to achieve or sustain profitability. We expect to finance our foreseeable cash requirements through cash on hand, cash from operations, debt financings and public or private equity offerings. We may seek to access the public or private equity markets whenever conditions are favorable; however, there can be no assurance that we will be able to raise additional capital when needed or on terms that are favorable to us, if at all. Additionally, we may seek collaborations and license arrangements for our drug candidates. We currently have no lines of credit or other arranged access to debt financing.

Financial Operations Overview

Revenue

We have not generated significant revenues to date. Our ability to generate revenues from our drug candidates will depend heavily on the successful development and eventual commercialization of our drug candidates.

In the future, we may generate revenue from a combination of product sales, third-party grants, service agreements, strategic alliances and licensing arrangements. We expect that any revenue we generate will fluctuate due to the timing and amount of services performed, milestones achieved, license fees earned and payments received upon the eventual sales of our drug candidates, in the event any are successfully commercialized. If we fail to complete the development of any of our drug candidates or obtain regulatory approval for them, our ability to generate future revenue will be adversely affected.

Research and development expenses

Research and development expenses consist of costs associated with our research activities, including the development of our drug candidates. Our research and development expenses consist of:

•

expenses related to research and development personnel, including salaries and benefits, travel and stock-based compensation;

TABLE OF CONTENTS

•

external research and development expenses incurred under arrangements with third parties, such as contract research organizations, clinical investigative sites, laboratories, manufacturing organizations and consultants; and

•

costs of materials used during research and development activities.

Costs and expenses that can be clearly identified as research and development are charged to expense as incurred. Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. If the goods will not be delivered, or services will not be rendered, then the capitalized advance payment is charged to expense.

We expect research and development expenses associated with the completion of the associated clinical trials to be substantial and to increase over time. The successful development of our drug candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete development of our drug candidates or the period, if any, in which material net cash inflows from our drug candidates may commence. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

•

the rate of progress, results and costs of completion of ongoing clinical trials of our drug candidates;

•

the size, scope, rate of progress, results and costs of completion of any potential future clinical trials and preclinical tests of our drug candidates that we may initiate;

•

competing technological and market developments;

•

the performance of third-party manufacturers and suppliers;

•

the ability of our drug candidates, if they receive regulatory approval, to achieve market success;

•

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our drug candidates; and

•

the impact, risks and uncertainties related to global pandemics and actions taken by governmental authorities or others in connection therewith.

A change in the outcome of any of these variables with respect to the development of a drug candidate could mean a significant change in the costs and timing associated with the development of that drug candidate. For example, if the FDA or other regulatory authority were to require us to conduct clinical trials beyond those which we currently anticipate will be required for the completion of clinical development of a drug candidate or if we experience significant delays in enrollment in any clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

General and administrative expenses

Our general and administrative expenses consist primarily of salaries and benefits for management and administrative personnel, professional fees for legal, accounting and other services, travel costs and facility-related costs such as rent, utilities and other general office expenses.

Net Loss. Our net loss was $16.1 million for the year ended December 31, 2023, an increase of $2.2 million compared to the year ended December 31, 2022.

Net Loss per Share. Net loss per share, both basic and diluted, was $33.63 per share for the year ended December 31, 2023, compared to $38.12 per share for the year ended December 31, 2022. Net loss per share is calculated using the weighted average number of shares of common stock outstanding during the applicable periods and excludes stock options and warrants because they are antidilutive.

Liquidity and Capital Resources

Overview

We have not generated significant revenues to date. Since our inception, we have funded our operations primarily through public and private offerings of our capital stock and other securities. We expect to finance our foreseeable cash requirements through cash on hand, cash from operations, debt financings and public or private equity offerings. We may seek to access the public or private equity markets whenever conditions are favorable; however, there can be no assurance that we will be able to raise additional capital when needed or on terms that are favorable to us, if at all. Additionally, we may seek collaborations and license arrangements for our drug candidates. We currently have no lines of credit or other arranged access to debt financing.

We had a cash balance of $0.6 million as of September 30, 2024, a decrease of $0.5 million compared to December 31, 2023. We do not believe that our available cash at September 30, 2024, together with the net proceeds received from the October 2024 Private Placement will be sufficient to meet obligations and fund our liquidity and capital expenditure requirements for the 12 months from November 14, 2024, the filing date of our Form 10-Q for the nine months ended September 30, 2024. The Company’s ability to continue as a going concern is dependent upon obtaining funding through one or more sources as described above to meet its planned obligations and pay its liabilities.

We are currently not in compliance with the Minimum Bid Price Rule and the Stockholder’s Equity Requirement of the Nasdaq Capital Market. We have been provided an initial period of 180 calendar days, or until June 10, 2025, to regain compliance with the Minimum Bid Price Rule. With respect to the Stockholder’s Equity Requirement, we must (i) demonstrate compliance with the minimum stockholders’ equity requirement of at least $2,500,000 pursuant to the Stockholders’ Equity Requirement, (ii) publicly disclose compliance with the Stockholder’s Equity Requirement in accordance with the terms of the Stockholders’ Equity Letter and (iii) provide the Panel with income projections for the next twelve months and evidence compliance with all applicable criteria for continued listing on the Nasdaq Capital Market. If we do not satisfy these requirements, we may be subject to delisting. The Panel reserves the right to reconsider the terms of the extension based on any event, condition or circumstance that exists or develops that would, in the opinion of the Panel, make continued listing inadvisable or unwarranted. There can be no assurance that we will be able to regain compliance with the Minimum Bid Price Rule or the Stockholders’ Equity Requirement by the applicable deadline. If we fail to comply with all listing standards applicable to issuers listed on the Nasdaq Capital Market, our common stock may be delisted. The delisting of our common stock could materially adversely affect our access to the capital markets and any limitation on liquidity or reduction in the price of our common stock could materially adversely affect our ability to raise capital.

2022 Shelf Registration Statement

On May 27, 2022, we filed a shelf registration statement on Form S-3 with the SEC, which was declared effective by the SEC on June 14, 2022 (File No. 333-265282) (the “2022 Shelf Registration Statement”), at which time the offering of unsold securities under a previous shelf registration statement on Form S-3 filed with the SEC, which was declared effective by the SEC on June 5, 2019 (File No. 333-231537) (the “2019 Shelf Registration Statement”), was deemed terminated pursuant to Rule 415(a)(6) under the Securities Act. The 2022 Shelf Registration Statement was filed to register the offering, issuance and sale of (i) up to $110.0 million of our common stock, preferred stock, warrants to purchase common stock or preferred stock or any combination thereof, either individually or in units, (ii) up to $9.0 million of our common stock under our At The Market Offering Agreement (the “Offering Agreement”), dated as of July 13, 2020, with H. C. Wainwright & Co., LLC (“Wainwright”), pursuant to which we could offer and sell, from time to time, through or to Wainwright, shares of our common stock, which $9.0 million was subsequently reduced to $3.0 million pursuant to a prospectus supplement filed with the SEC on July 29, 2022, and (iii) up to 11,895 shares of our common stock pursuant to the exercise of warrants outstanding on May 27, 2022. The $3.0 million of our common stock that could previously be offered, issued and sold under the Offering Agreement was included in the $110.0 million of our securities that may be offered, issued and sold. On December 7, 2022, we received written notice from Wainwright that Wainwright had elected, pursuant to Section 8(b) of to terminate the Offering Agreement effective as of December 7, 2022, at which time all

TABLE OF CONTENTS

$3.0 million of shares of our common stock remained available for sale thereunder. As a result of the termination of the Offering Agreement, we will not offer or sell any additional shares of our common stock thereunder, and the entire $3.0 million of shares of our common stock previously available for sale under the Offering Agreement will be available for sale in other offerings pursuant to the 2022 Shelf Registration Statement. Because our public float is less than $75.0 million, our ability to offer and sell any securities under the 2022 Shelf Registration Statement is currently limited pursuant to Instruction I.B.6 to Form S-3. For so long as our public float is less than $75.0 million, the aggregate market value of securities we sell pursuant to Instruction I.B.6 to Form S-3 during any 12 consecutive months may not exceed one-third of our public float. The foregoing does not constitute an offer to sell or the solicitation of an offer to buy securities, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of that jurisdiction.

2022 Registered Direct Offering and 2022 Private Placement

On November 6, 2022, we entered into a placement agency agreement with Roth Capital Partners, LLC relating to the 2022 Registered Direct Offering and the 2022 Private Placement. In addition, on November 6, 2022, we entered into securities purchase agreements with several institutional and accredited investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 40,000 shares of our common stock for gross proceeds of approximately $2.0 million under the base prospectus contained in the 2022 Shelf Registration Statement and a related prospectus supplement filed with the SEC on November 9, 2022 (the “2022 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreements to issue to such investors warrants to purchase up to 40,000 shares of our common stock (the “2022 Private Placement”). The 2022 Registered Direct Offering and the 2022 Private Placement closed on November 9, 2022.

Future Capital Requirements

We expect to continue to incur significant operating expenses in connection with our ongoing activities, including conducting clinical trials, manufacturing and seeking regulatory approval of our drug candidates, prexigebersen, BP1002, BP1003 and BP1001-A. Accordingly, we will continue to require substantial additional capital to fund our projected operating requirements. Such additional capital may not be available when needed or on terms favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current and future operating plan. There can be no assurance that we will be able to continue to raise additional capital through the sale of our securities in the future. Our future capital requirements may change and will depend on numerous factors, which are discussed in detail in the “Risk Factors” section of this prospectus. For more information, see Note 1 to the Unaudited Condensed Consolidated Financial Statements included herein.

Off-Balance Sheet Arrangements

As of September 30, 2024, we did not have any material off-balance sheet arrangements.

Critical Accounting Policies

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in conformity with GAAP in the U.S. The preparation of such financial statements has required our management to make assumptions, estimates and judgments that affect the amounts reported in the financial statements, including the notes thereto, and related disclosures of commitments and contingencies, if any. We consider our critical accounting policies to be those that require the more significant judgments and estimates in the preparation of financial statements, including the following:

Research and Development Costs — Costs and expenses that can be clearly identified as research and development are charged to expense as incurred. Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. If the goods will not be delivered, or services will not be rendered, then the capitalized advance payment is charged to expense.

The Company estimates its clinical trial expense accrual each period based on a cost per patient calculation which is derived from estimated start-up costs, clinical trial costs based on the number of patients and length of treatment and clinical study report costs. These services are performed by the Company’s third-party clinical research organizations, laboratories and clinical investigative sites. The expense accrual is recorded in research and development expense each period. Amounts that have been prepaid in advance of work performed are recorded in other current assets.

For the year ended December 31, 2023 and for the nine months ended September 30, 2024, we had $11.6 million and $5.5 million, respectively, of costs classified as research and development expense.

BUSINESS

Overview

We are a clinical and preclinical stage oncology- and obesity-focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target-specific protein inhibition for any gene product that is over-expressed in disease. Our drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a lipid bilayer having neutral charge. We believe this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. Through testing in numerous animal studies and dosing in clinical trials our DNAbilize® drug candidates have demonstrated an excellent safety profile. DNAbilize® is a registered trademark of the Company.

Using DNAbilize® as a platform for drug development and manufacturing, we currently have four drug candidates in development to treat at least five different cancer disease indications. Our lead drug candidate, BP1001, or “prexigebersen” (pronounced prex” i je ber’ sen), which is being developed to target growth factor receptor-bound protein 2 (“Grb2”), initially started the efficacy portion of a Phase 2 clinical trial for untreated acute myeloid leukemia (“AML”) patients in combination with low-dose cytarabine (“LDAC”). However, the changing landscape of AML treatment has led to removing the combination treatment of prexigebersen and LDAC and replacing it with the combination treatment of prexigebersen and decitabine.

Our approved Phase 2 clinical trial currently has three cohorts of subjects. The first two cohorts will treat patients with the triple combination of prexigebersen, decitabine and venetoclax. The first cohort will include untreated AML patients, and the second cohort will include relapsed/refractory AML patients. Finally, the third cohort will treat relapsed/refractory AML patients, who are venetoclax-resistant or -intolerant, with the two-drug combination of prexigebersen and decitabine. The full trial design plans have approximately 98 evaluable patients for the first cohort having untreated AML patients with a preliminary review performed after 19 evaluable patients and a formal interim analysis after 38 evaluable patients. The full trial design plans have approximately 54 evaluable patients for each of the second cohort, having relapsed/refractory AML patients, and the third cohort, having AML patients who are venetoclax-resistant or -intolerant, in each case with a review performed after 19 evaluable patients. The study is anticipated to be conducted at up to ten clinical sites in the U.S., and Gail J. Roboz, MD, is the national coordinating Principal Investigator for the Phase 2 trial. Dr. Roboz is a professor of medicine and director of the Clinical and Translational Leukemia Program at the Weill Medical College of Cornell University (the “Weill Medical College”) and the New York-Presbyterian Hospital in New York City. The safety run-in of the triple combination of prexigebersen, decitabine and venetoclax of the Phase 2 clinical study was successfully completed. The preliminary data, presented at the 2021 ASH Annual Meeting, showed the treatment was well-tolerated and there were no dose limiting toxicities attributed to prexigebersen.

patients is being conducted at the Georgia Cancer Center, The University of Texas Southwestern and New York Medical College. A total of six evaluable patients are scheduled to be treated over two dose levels with BP1002 monotherapy in a standard 3+3 design. Enrollment has been successfully completed for both dose cohorts, 20 and 40 mg/m2. There were no dose-limiting toxicities. On December 11, 2024, we announced that the Phase 1 clinical trial evaluating BP1002 as a treatment for refractory/relapsed lymphoma and refractory/relapsed CLL has discontinued enrollment. This decision was based on enrollment challenges in these niche indications, particularly given the crowded development landscape that includes multiple competing trials.

Preclinical studies suggest that the combination of BP1002 with decitabine is efficacious in venetoclax-resistant cells. A Phase 1/1b clinical trial to investigate the ability of BP1002 to treat refractory/relapsed AML patients, including venetoclax-resistant patients, is being studied. A recent study1 found that AML patients who had relapsed from frontline venetoclax-based treatment had a very poor prognosis, with a median survival of less than three months. Since venetoclax and BP1002 utilize different mechanisms of action, we believe that BP1002 may be a potential treatment for venetoclax-relapsed AML patients. The Phase 1/1b clinical trial is being conducted at several leading cancer centers in the United States, including the Weill Medical College, The University of Texas MD Anderson Cancer Center (“MD Anderson”), Scripps Health and The University of California at Los Angeles Cancer Center. A total of four BP1002 monotherapy cohorts with three evaluable patients per dosing cohort, in a standard 3+3 design, are scheduled. On October 7, 2024, we announced that the FDA had completed its review of pharmacokinetic/pharmacodynamic (“PK/PD”) data from the first two dosing cohorts (20 and 40 mg/m2). Enrollment for the third dosing cohort (60 mg/m2) is now complete. We expect to enroll the next planned higher dose of 90 mg/m2 in the first quarter of 2025. The approved treatment cycle is two doses per week over four weeks, resulting in eight doses administered over twenty-eight days. The Phase 1b portion of the study is expected to commence after completion of BP1002 monotherapy cohorts and will assess the safety and efficacy of BP1002 in combination with decitabine in refractory/relapsed AML patients.

Our third drug candidate, Liposomal STAT3 (“BP1003”), targets the STAT3 protein and is currently in IND enabling studies as a potential treatment of pancreatic cancer, non-small cell lung cancer (“NSCLC”) and AML. Preclinical studies showing BP1003’s ability to inhibit STAT3 protein expression and cancer cell viability had been presented at AACR Annual Meetings. On September 16, 2024, we announced a publication in the peer-reviewed journal, Biomedicines, which highlights the therapeutic potential and broad anti-tumor effect of BP1003 in numerous preclinical solid tumor models, including breast, ovarian, and pancreatic cancer. We have successfully completed several IND enabling studies of BP1003 and have one additional IND enabling study to complete. Once the additional study is successfully completed, our goal is to file an IND application and initiate the first-in-humans Phase 1 study of BP1003 in patients with refractory, metastatic solid tumors, including pancreatic cancer and NSCLC.

In addition, a modified product named BP1001-A, our fourth drug candidate, has shown to enhance chemotherapy efficacy in a preclinical study involving solid tumor models. Results of the preclinical study were published in the scientific journal Oncotarget in July 2020. BP1001-A incorporates the same drug substance as prexigebersen but has a slightly modified formulation designed to enhance nanoparticle properties. A BP1001-A Phase 1/1b clinical trial in patients with advanced or recurrent solid tumors is being conducted at several leading cancer centers in the United States, including MD Anderson, Karmanos Cancer Institute, Mary Crowley Cancer Research and Holy Cross Hospital, Maryland. A total of nine evaluable patients are scheduled to be treated with BP1001-A monotherapy over three dose levels in a standard 3+3 dose escalation design. The first dose cohort consisted of a starting dose of 60 mg/m2 had been completed, and there were no dose limiting toxicities. Enrollment is now open for patients for the second dose cohort of 90 mg/m2 which we expect to be complete in the first quarter of 2025 in order to advance to dose level 3. The Phase 1b portion of the study is expected to commence after successful completion of BP1001-A monotherapy cohorts and is intended to assess the safety and efficacy of BP1001-A in combination with paclitaxel in patients with recurrent ovarian or endometrial tumors. Phase 1b studies are also expected to be opened in combination with gemcitabine in Stage 4 pancreatic cancer and combination therapy in breast cancer.

Development and Treatment for Obesity

Insulin resistance is a major contributor to obesity, Type 2 diabetes and other related metabolic diseases. Scientific evidence suggests that Grb2 regulates insulin signaling and blood glucose level. On December 19, 2024, we announced the results of our initial preclinical work confirming that BP1001-A affected the insulin pathway and increased insulin sensitivity, thus validating BP1001-A as a potential treatment for obesity in Type 2 diabetes patients. We have initiated animal studies to confirm the efficacy of BP1001-A as a potential treatment for obesity and related metabolic diseases in Type 2 diabetes patients. If successful, we anticipate initiating a first-in-human Phase 1 clinical trial in 2025 to further validate safety, measure pharmacokinetics and establish dosing for potential pivotal trials.

We are developing a molecular biomarker package to accompany prexigebersen treatment, the goal of which is to identify patients with a genetic profile more likely to respond to the investigational treatment and thereby improve the probability of success for this program as a result. The emerging role of biomarkers has been enhancing cancer development over the past decade and has become a more common companion to many cancer development programs. We expect to develop molecular biomarker packages to accompany our new programs.

We have certain intellectual property as the basis for our current drug products in clinical development, prexigebersen, BP1002, BP1003 and BP1001-A. We are developing RNAi antisense nanoparticle drug candidates based on our own patented technology to treat cancer, obesity and autoimmune disorders where targeting a single protein may be advantageous and result in reduced patient adverse effects as compared to small molecule inhibitors with off-target and non-specific effects. We have composition of matter and method of use intellectual property for the design and manufacture of antisense RNAi nanoparticle drug products.

Our basic drug development concept is to block expression of proteins associated with disease. Messenger RNA (“mRNA”) is essential in the process of creating proteins. We have developed DNAbilize® nanoparticle drug delivery systems to deliver short strands of antisense DNA drugs to cells and block the production of proteins associated with disease progression.

Antisense therapeutics have been in development for over 20 years. However, challenges to antisense therapeutics, such as instability of antisense drugs inside of the body and inefficient delivery of antisense to disease cells, have thawed antisense therapeutic potential. We believe our DNAbilize® technology, which is the combination of the protected P-ethoxy antisense DNA backbone with the neutral liposome nanoparticle, is the ideal approach for antisense DNA therapeutics because it overcomes the challenges associated with both antisense stability and intracellular delivery. The P-ethoxy modification used in our DNAbilize® technology is completely sulfur free. We avoid using sulfur-containing antisense because it has been associated with causing liver toxicity and life-threatening bleeding and clotting complications. We prefer neutral lipids to cationic lipids for intracellular delivery because encapsulating the antisense DNA inside a neutral charged lipid bilayer facilitates the delivery and transfer of DNA into the cell to be fluid and gentle. DNAbilize® is truly a stand-alone platform because, as demonstrated by our published preclinical and clinical studies, it allows for high doses of drug products to be delivered throughout the entire body while minimizing toxicity. This allows our research and development efforts to focus on drug targets rather than on indications because the DNAbilize® system should not be limited in what types of indications it can treat. As such, we believe that DNAbilize® represents the first ever antisense therapeutic approach that can successfully treat hematological and systemic diseases.

Strategy

Because of our unique ability to address unmet needs in hematological malignancies, our lead drug candidates focus on cancers of the blood and lymph. Our strategy is to develop prexigebersen, BP1002, BP1003 and BP1001-A for multiple indications where the pathways involving Grb2, Bcl-2 and STAT3, respectively, are utilized to promote cancer growth, survival, angiogenesis and tumor surveillance evasion. Using DNAbilize® technology, we plan to develop therapeutics to a wide range of diseases and disorders independently and in partnership with others. Our strategy includes:

•

Developing prexigebersen for treatment of AML in combination therapies.

•

Developing BP1002 for refractory/relapsed AML patients, including venetoclax-resistant patients.

•

Developing BP1003 for pancreatic and lung cancer.

•

Developing BP1001-A for treatment of solid tumors, including ovarian, endometrial and pancreatic cancer.

•

Developing BP1001-A for treatment of obesity and related metabolic diseases.

•

Expanding DNAbilize® to evaluate targets beyond cancer.

•

Establishing DNAbilize® as the antisense drug delivery method of choice by forming partnerships with pharmaceutical and academic clinical research labs.

•

Establishing a molecular biomarker package to accompany prexigebersen treatment.

Overview of Drug Candidates

The historical perspective of cancer treatments has been the use of drugs that affect the entire body. Advances in the past decades have shifted to treating the tumor tissue itself. One of the main strategies in these developments has been targeted therapy, involving drugs that are targeted to block the expression of specific disease-causing proteins while having little or no effect on other healthy tissues. We believe that nucleic acid drug products, specifically antisense, are a promising field of targeted therapy. Development of antisense as cancer drugs, however, has been limited by the lack of a suitable method to deliver antisense drugs to cancer cells with high uptake into the cancer cells without causing toxicity to non-cancer cells. Our patented DNAbilize® neutral-lipid based liposome technology is designed to overcome these limitations. We have published preclinical studies demonstrating that our DNAbilize® technology could efficiently deliver antisense therapeutics to mouse models of hematological malignancies and solid tumors, decrease target proteins production and suppress tumor progression. In addition, to date, no adverse effects attributed to the study drugs have been observed in our cancer clinical trials.

PREXIGEBERSEN

Prexigebersen is targeted at the protein Grb2, a bridging protein between activated and mutated cellular kinases and the proteins involved in cell propagation, and in particular, a well-known cancer associated switch called Ras protein. When mutations occur that activate these kinases, the cell propagates uncontrollably, via Grb2, and this results in disease progression. Antisense inhibition of Grb2 interrupts the signals between mutated and activated receptors that connect to the Ras protein. This inhibition suppresses cancer cell propagation and does not result in adverse events typically observed with receptor inhibitors or Ras pathway inhibitors. We believe that prexigebersen has the potential to be an ideal combination for any number of cancer therapeutics where the Ras pathway is aberrantly activated and patient fitness is a major concern, such as in AML.

Indications for Acute Myeloid Leukemia (AML)

AML — Background and Common Treatments. AML is the rapid accumulation of immature myeloid cells in the blood, resulting in a drop of the other cell types such as red blood cells and platelets. AML incidence increases with age, with more than 50% of the cases in people aged 60 or older. AML is the most common acute leukemia in adults, and the National Cancer Institute estimated that approximately 20,800 new cases occurred in 2024 (Table 1). The five-year survival rate is approximately 11% in older adults (ages 65+).

TABLE OF CONTENTS

The Bcl-2 inhibitor venetoclax is approved for newly diagnosed AML patients aged 75 years and older or adults who cannot be treated with intensive induction chemotherapy. Venetoclax is used in combination with LDAC, decitabine or azacytidine. Mutation in the Bcl-2 binding domain, which reduces venetoclax’s ability to bind to Bcl-2, has been linked with venetoclax resistance in CLL patients. Such venetoclax resistance may also occur in AML patients. AML remains an area of high unmet need for both the relapsed and the newly diagnosed elderly population who are typically ineligible for induction therapy.

Table 1. Basic Statistics for AML

Prexigebersen Development and Treatment for Leukemia. The safety, pharmacokinetics and efficacy of our lead DNAbilize® antisense drug candidate, prexigebersen, was assessed in patients having AML, CML, myelodysplastic syndrome (MDS) or acute lymphoblastic leukemia (“ALL”) in a Phase 1 trial. The Phase 1 clinical trial was a dose-escalating study to determine the safety and tolerability of escalating doses of prexigebersen. After completion of dose-escalation monotherapy, the safety and toxicity of prexigebersen in combination with LDAC was assessed in patients with refractory/relapsed AML. Additionally, the pharmacokinetics and anti-leukemic effects, including down-regulation of the target Grb2 protein in patient samples, of the drug candidate were determined. Results of the Phase 1 clinical study were published in the scientific journal Lancet Haematology in 2018.

Phase 1 Clinical Trial

Among the 39 patients enrolled in the study, 12 patients were removed from study before the end of cycle 1 because of disease progression or death, without dose-limiting toxicity, and were replaced per protocol guidelines. The approved prexigebersen treatment cycle is two doses per week over four weeks, resulting in eight doses administered over 28 days. Among the 27 evaluable patients, 21 patients were treated with escalating doses of prexigebersen monotherapy and six patients were treated with prexigebersen plus LDAC (Figure 1). The dose-limiting toxicity was not reached in the prexigebersen monotherapy cohorts, up to the maximum dose of 90 mg/m2. The prexigebersen plus LDAC combination was also well tolerated, with a toxicity profile similar to that of prexigebersen monotherapy, including the absence of identifiable dose-limiting toxicity. Furthermore, five patients receiving prexigebersen plus LDAC combination experienced at least a 50% reduction in bone marrow blasts; two patients achieved a CR, one achieved CRi, and two had stable disease. These results demonstrate the potential anti-leukemic activity of prexigebersen and its potential to stabilize patients for extended treatments.

A flow cytometry scientific assay was used to provide critical proof that DNAbilize® neutral liposome delivery technology delivered the drug substance to the cell and was able to transport it across the cell membrane into the interior to block cellular production of the Grb2 protein. The extent by which prexigebersen inhibited the expression of the target Grb2 protein and the expression of phosphorylated extracellular signal related kinase (pERK), a protein downstream of the Ras protein, in patient samples was investigated. By the end of the treatment, prexigebersen decreased Grb2 protein levels in 10 out of 12 samples (83%) tested (average reduction 50%) compared to the baseline Grb2 levels prior to treatment. Similarly, by the end of the treatment, prexigebersen decreased pERK levels in seven out of 12 samples (58%) tested (average reduction 52%) compared to the baseline pERK levels prior to treatment. Additionally, pharmacokinetics of prexigebersen demonstrated a half-life at 60 mg/m2 of 30 hours, significantly better than the 90 mg/m2 dose. The final analysis of these data, along with the demonstrated reductions in bone marrow blasts, suggested that 60 mg/m2 is the appropriate dose for use in the Phase 2 trial.

Phase 2 Clinical Trials

Results from the Phase 1b clinical trial demonstrated it is safe to add prexigebersen to LDAC, which appears to yield better response rates in this AML patient population. A Phase 2 study was initiated to assess the efficacy of prexigebersen plus LDAC in newly diagnosed AML patients. Thirty patients were enrolled and 17 patients were deemed evaluable (Table 2). The interim data, presented at the 2018 ASH Annual Meeting, showed that 11 (65%) of the 17 evaluable patients had a response, including five (29%) who achieved CR, including one CRi and one morphologic leukemia free state, and six (35%) stable disease responses, including two patients who had greater than a 50% reduction in bone marrow blasts. The efficacy data from the 17 evaluable patients was very favorable compared to the reported CR, CRp and CRi rates of 7 to 13% with LDAC treatment alone. Importantly, through investigation by the principal investigators, it was observed that 68% of patients were secondary AML patients, a difficult class to treat.

Results to date have shown prexigebersen, with its efficacy and excellent safety profile, to be an effective combination candidate with frontline therapy. However, the changing landscape of AML treatment has led to amendment of the Phase 2 clinical study by removing the combination treatment of prexigebersen and LDAC and replacing it with the combination treatment of prexigebersen and decitabine.

We believe the approval of the frontline venetoclax and decitabine combination therapy provides an opportunity for combining prexigebersen with the combination therapy for the treatment of newly diagnosed AML patients. Preclinical testing of prexigebersen with venetoclax and decitabine demonstrated the potential to enhance efficacy of the frontline treatment combination. The triple combination of prexigebersen, venetoclax and decitabine showed significant improvement in decreasing the viability of three of the four AML cell lines tested. Bio-Path’s approved amended Stage 2 for this Phase 2 clinical trial has three cohorts of patients. The first two cohorts will treat patients with the triple combination of prexigebersen, decitabine and venetoclax with the first cohort including untreated AML patients and the second cohort including relapsed/refractory AML patients. Finally, the third cohort will treat relapsed/refractory AML patients who are venetoclax-resistant or -intolerant with the two-drug combination of prexigebersen and decitabine.

The safety run-in study of the two-drug combination of prexigebersen and decitabine as well as that of the triple combination of prexigebersen, decitabine and venetoclax were successfully completed. The preliminary data, presented at the 2021 ASH Annual Meeting, showed the treatments were well-tolerated and there were no dose limiting toxicities attributed to prexigebersen.

On June 3, 2024, we announced additional interim data for the first two cohorts of the Phase 2 clinical trial (Tables 2 and 3). In cohort 1, 31 newly diagnosed patients were enrolled; 20 evaluable patients with a median age of 75 years, treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk or secondary AML evolved from myelodysplastic syndromes, chronic myelomonocytic leukemia or treatment-related AML. Fifteen patients (75%) achieved complete remission, CR with CRh, or CRi. One patient achieved partial remission (“PR”), three patients achieved stable disease, and one patient had toxicity attributed to decitabine and venetoclax treatment (Table 2).

Table 2. Interim data of evaluable newly diagnosed AML patients who were treated with the prexigebersen + decitabine + venetoclax combination treatment

TABLE OF CONTENTS

In cohort 2, 40 relapsed/refractory patients were enrolled; 23 evaluable patients with a median age of 63 years, treated with at least one cycle of prexigebersen, decitabine and venetoclax, had adverse-risk or secondary AML. Twelve patients (55%) achieved CR/CRi/CRh, one patient achieved PR, eight patients achieved stable disease and two patients had progressive disease or treatment failure (Table 3).

Table 3. Interim data of evaluable refractory/relapsed AML patients who were treated with the prexigebersen + decitabine + venetoclax combination treatment

$[MISSING IMAGE: tb_refractory-4c.jpg]$

Among the evaluable patients of both cohorts, adverse events were consistent with those expected with decitabine and venetoclax and/or AML, including fatigue (72%), anemia (60%) and neutropenia (49%), while the most frequent severe adverse events were febrile neutropenia (26%) and sepsis (5%). The interim analysis data was selected as an oral presentation in the 2024 ASCO Annual Meeting and as a poster presentation in the 2024 EHA Annual Meeting. Based on this interim data, we expect to continue enrollment of up to 98 and 54 evaluable patients for cohorts 1 and 2, respectively and plan to pursue FDA expedited programs for Fast Track designation. We are evaluating whether to seek to expand Stage 2 of the Phase 2 clinical trial in Europe. We expect to complete enrollment in cohorts 1 and 2 in 2026.

BP1002

BP1002, also known by its scientific name as Liposomal Bcl-2, is our second liposome delivered antisense drug candidate. BP1002 is intended to target lymphoma, CLL, AML and certain solid tumor markets. We believe that BP1002 has the potential to treat 40 to 60% of solid tumors.

Bcl-2 is a protein that is involved in regulating apoptosis, or programmed cell death. Apoptosis is a physiologic mechanism of cell turnover by which cells actively commit suicide in response to aberrant external signals. Over-expression of Bcl-2 prevents the induction of apoptosis in response to cellular insults such as treatment with chemotherapeutic agents. Bcl-2, initially discovered in transformed follicular lymphoma (“FL”) was found to contribute to the pathophysiology of various subtypes of non-Hodgkin’s lymphoma (“NHL”).

BP1002 — Development and Treatment for lymphoma

Therapies that directly and specifically block or inhibit protein synthesis of Bcl-2 could be transformative for NHL. The Bcl-2 inhibitor venetoclax was approved by the FDA for the treatment of patients with CLL and small lymphocytic leukemia (“SLL”). However, treatment with venetoclax can lead to the development of drug resistance, resulting in disease recurrence. One of the proposed mechanisms of venetoclax resistance is acquired mutations in Bcl-2, which reduce venetoclax’s ability to bind and inhibit Bcl-2. Because BP1002 activity is based on blocking the Bcl-2 messenger RNA and BP1002 targets Bcl-2 at a site different from venetoclax, we expect BP1002 to overcome such venetoclax resistance mechanism and be an effective approach for patients who have relapsed from venetoclax.

The Phase 1 clinical trial evaluating the ability of BP1002 to treat refractory/relapsed lymphoma and refractory/relapsed CLL patients is being conducted at the Georgia Cancer Center, The University of Texas Southwestern and New York Medical College. Initially, a total of six evaluable patients are scheduled to be treated with BP1002 monotherapy in a standard 3+3 design. The approved treatment cycle is two doses

TABLE OF CONTENTS

per week over four weeks, resulting in eight doses administered over twenty-eight days. Enrollment for both dose cohorts, 20 and 40 mg/m2, has been successfully completed. There were no dose limiting toxicities.

BP1002 — Development and Treatment for AML

The Bcl-2 inhibitor venetoclax is used in frontline combination therapies to treat elderly AML patients; however, venetoclax resistance has been observed. A recent study2 found that AML patients who had relapsed from frontline venetoclax-based treatment had a very poor prognosis, with a median survival of less than three months. Since venetoclax and BP1002 utilize different mechanisms of action, we believe that BP1002 may be a potential treatment for venetoclax-relapsed AML patients. Preclinical studies, presented at the 2021 American Association for Cancer Research Annual Meeting, suggest that the combination of BP1002 with decitabine is efficacious in venetoclax-resistant AML cells. A Phase 1/1b clinical trial to investigate the ability of BP1002 to treat refractory/relapsed AML patients, including venetoclax-resistant patients, is being conducted at several leading cancer centers in the United States, including the Weill Medical College, MD Anderson Cancer Center, Scripps Cancer Center and The University of California at Los Angeles Cancer Center. Gail J. Roboz, M.D., is serving as the national coordinating Principal Investigator for the Phase 1/1b trial. Gary Schiller, M.D., The University of California at Los Angeles Cancer Center, Maro Ohanian, D.O., Department of Leukemia, University of Texas MD Anderson Cancer Center, and David Hermel, M.D., Scripps Health, will each serve as Principal Investigators.

A total of three evaluable patients per dosing cohort are scheduled to be treated with BP1002 monotherapy in a standard 3+3 design. The approved treatment cycle is two doses per week over four weeks for a total of eight doses administered over 28 days. On October 7, 2024, we announced that the FDA had completed its review of PK/PD data from the first two dosing cohorts (20 and 40 mg/m2) and that the enrollment for the third dosing cohort (60 mg/m2) is now complete. We expect to enroll in the next planned higher dose of 90 mg/m2 in the first quarter of 2025. The Phase 1b portion of the study is expected to commence after completion of BP1002 monotherapy cohorts and will assess the safety and efficacy of BP1002 in combination with decitabine in refractory/relapsed AML patients.

BP1003

BP1003 is our third liposome delivered antisense drug candidate. BP1003 is a DNAbilize® RNAi nanoparticle containing antisense DNA targeting STAT3, whose elevated expression/activity is associated with a poorer survival outcome for patients with solid tumors, including those of gastric cancer, lung cancer, hepatic cancer, osteosarcoma, prostate cancer and pancreatic adenocarcinoma (“PDAC”). We believe that a therapeutic that shuts down the STAT3 protein can have significant clinical impact for solid tumors that have elevated expression/activity of STAT3.

Our lead indication for BP1003 is pancreatic cancer due to the severity of this disease and the lack of effective, life-extending treatments. It is estimated that less than 11% of PDAC patients survive beyond five years, and it is projected that by 2030, PDAC will become the second most lethal cancer behind lung cancer. Treatment of the disease is hampered by the location of the pancreas, which is difficult to reach with conventional therapies and the fibrotic nature of the tumors, which protects them from penetration by chemotherapeutics. We believe a novel and unconventional therapeutic is needed to overcome these barriers to treatment.

While competition for therapeutics that target the STAT3 pathway exists, the competition for specific STAT3 inhibitors is very small. Many peptides designed to bind to STAT3 suffered from poor intrinsic pharmacokinetic properties, including poor cellular permeability and lack of stability in vivo, which curtailed their further development. Even second-generation peptidomimetics have failed to overcome these limitations.

(Maiti A, Ruasch C, Cortes JE, et.al. Outcomes of relapsed or refractory acute myeloid leukemia after frontline hypomethylating agent and venetoclax regimens. Haematologica 2021; 106: 894-898.)

TABLE OF CONTENTS

Most compounds under development target the pathway upstream of STAT3, such as the JAK2 kinase. However, lack of efficacy of the JAK2 kinase inhibitors was observed in PDAC clinical studies. Ionis Pharmaceuticals, Inc. has developed an antisense DNA-based STAT3 inhibitor called IONIS-STAT3-2.5Rx. It is being evaluated in clinical trials by AstraZeneca under the name AZD9150 for solid tumors and NHL. However, due to the toxicity of the DNA chemistry, thrombocytopenia continues to limit the systemic delivery and efficacy of such compounds for the treatment of cancer. We believe BP1003 avoids these complications.

We hypothesized that the natural lipid delivery vesicle would have unique characteristics that would allow for penetration of the fibrotic stroma to reach the PDAC cells. Our preclinical work demonstrated that BP1003 was successful in crossing the scar tissue matrix and delivering antisense drug into the tumor tissue. Results of our preclinical work were published in the scientific journal Biomedicines in August 2024. The publication highlights the therapeutic potential and broad anti-tumor effect of BP1003 in numerous preclinical solid tumor models, including breast, ovarian, and pancreatic cancer. BP1003 enhanced the sensitivity of breast and ovarian cancer cell lines to chemotherapy, such as paclitaxel and 5-fluorouracil. Moreover, ex vivo and in vivo patient-derived models of PDAC showed reduced tissue viability and tumor volume with BP1003 and gemcitabine combination treatments. In addition to directly affecting tumor cells, BP1003 can modulate the tumor microenvironment by suppressing monocyte differentiation into anti-inflammatory M2 macrophages.

We have successfully completed several IND enabling studies of BP1003, including safety. Body weight was used as an indicator of BP1003 safety in rodents. Mice received saline or twice weekly injections of BP1003 for four weeks. There was no difference in body weight between control mice and BP1003-treated mice (Figure 1). We have one additional IND enabling study to complete. Once the additional study is successfully completed, our goal is to file an IND and initiate the first-in-humans Phase 1 study of BP1003 in patients with refractory, metastatic solid tumors, including pancreatic cancer and NSCLC.

Figure 1. No difference in mean body weight was observed between control groups
and BP1003-treated groups

[MISSING IMAGE: bc_meanbodyweight-4clr.jpg]

We believe that the excellent safety profile of the DNAbilize® chemistry, the novel lipid formula that allows for penetration of the tumor stroma, and the ability to target a single protein with precision, makes BP1003 an ideal candidate for combination with approved treatments to extend survival while maintaining quality of life for the patient.

BP1001-A

Data supports a prominent role of Grb2 in the progression of solid tumors, and overexpression of Grb2 has been associated with chemosensitivity, poor prognosis and advanced disease in several malignancies including gynecologic malignancies.

Indications for Solid Tumors (e.g., Ovary, Endometrium)

Ovarian cancer is one of the most common types of gynecologic malignancy. In the U.S., 19,680 new cases of and 12,740 deaths from ovarian cancer were expected in 2024 (Table 4). According to the Ovarian Cancer Research Alliance, approximately 70% of patients diagnosed with ovarian cancer will have a recurrence. Recurrent ovarian cancer is treatable but rarely curable. The response rates to second-line chemotherapy are low and differ by platinum-sensitivity status: 20 to 25% for platinum-sensitive cases and

TABLE OF CONTENTS

10 to 20% for platinum-resistant cases3. Given the poor outcomes of treatment for ovarian cancer, novel drug treatments are urgently needed.

Table 4. Basic Statistics for Ovarian Cancer

Endometrial cancer is the most common gynecologic malignancy in the U.S. In the U.S., 67,880 new cases of and 13,250 deaths from endometrial cancer were expected in 2024 (Table 5). The majority of cases are diagnosed at an early stage and are amenable to treatment with surgery alone. However, approximately 38 to 67% of advanced stage endometrial cancers will recur4. Recurrent endometrial cancer is incurable with currently available standard therapies. The median survival for patients with recurrent endometrial carcinoma is approximately 12 to 15 months5. Novel drug treatments for recurrent endometrial carcinoma are urgently needed.

Table 5. Basic Statistics for Endometrial Cancer

Development and Treatment for Ovarian and Endometrial cancer

Grb2 may be a novel potential therapeutic target for ovarian and endometrial cancer, and BP1001-A may provide clinical benefit against these gynecologic malignancies. BP1001-A is a modified drug product with the same drug substance as prexigebersen but includes formulation enhancements to produce smaller drug nanoparticles. The goal of this product enhancement is to produce smaller drug nanoparticles that can pass through vasculature pore spaces, thereby enabling release of the drug product into the interior of the tumor to enhance drug effectiveness. Results of the preclinical study, conducted in collaboration with leaders in the field of ovarian cancer at MD Anderson Cancer Center, were published in the scientific journal Oncotarget in July 2020. BP1001-A effectively penetrated ovarian tumors and decreased target Grb2 protein level in preclinical ovarian and endometrial tumor models. BP1001-A was demonstrated to reduce tumor burden both as a monotherapy and in combination with paclitaxel, a therapy commonly used to treat patients with advanced ovarian or endometrial cancer.

A Phase 1/1b clinical trial of BP1001-A in patients with advanced or recurrent solid tumors has been initiated. The dose escalation portion of the Phase 1/1b clinical trial is ongoing at several leading cancer centers in the United States, including MD Anderson, The Mary Crowley Cancer Research Center, and Karmanos Cancer Center. Initially, a total of nine evaluable patients are scheduled to be treated with BP1001-A monotherapy in a standard 3+3 design, with a starting dose of 60 mg/m2 and continuing with 90 mg/m2 and 135 mg/m2. The approved treatment cycle is two doses per week over four weeks, resulting in eight doses administered over 28 days. The Phase 1b portion of the study is expected to commence after successful completion of BP1001-A monotherapy cohorts and is intended to assess the safety and efficacy of BP1001-A in combination with paclitaxel in patients with recurrent ovarian or endometrial tumors.

TABLE OF CONTENTS

The first dose cohort of BP1001-A in the Phase 1/1b study had been successfully completed. Three patients were enrolled into the first dose cohort of BP1001-A at three different centers in the study, including one patient with hepatic lesions (and lung metastases) and two with advanced gynecologic lesions. All three patients had undergone extensive previous chemotherapies and/or surgeries for their disease prior to enrollment in this study. No patient experienced any treatment related adverse events or any adverse events deemed related to the study drug. Enrollment is now open for patients for the second dose cohort of 90 mg/m2 which we expect to be complete in the first quarter of 2025 in order to advance to dose level 3. The Phase 1b portion of the study is expected to commence after successful completion of BP1001-A monotherapy cohorts and is intended to assess the safety and efficacy of BP1001-A in combination with paclitaxel in patients with recurrent ovarian or endometrial tumors. Phase 1b studies are also expected to be opened in combination with gemcitabine in Stage 4 pancreatic cancer and combination therapy in breast cancer.

Indications for Triple Negative Breast Cancer (TNBC) and Inflammatory Breast Cancer (IBC)

TNBC and IBC — Background and Common Treatments. Approximately 15 to 20% of breast cancers fall into the category of triple-negative. TNBC tumors do not express estrogen receptors, progesterone receptors, and low human epidermal growth factor receptor 2 (“HER2”). These negative indicators mean that the growth of the cancer is not supported by the hormones estrogen and progesterone, or by the presence of HER2 receptors. Therefore, TNBC does not respond to hormonal therapy or therapies that target HER2 receptors. In addition, TNBC tumors are very aggressive. IBC is a rare and very aggressive type of breast cancer that accounts for 2 to 5% of all breast cancers. A lack of targeted treatments for these types of breast cancer has led to development of new therapeutics currently in clinical trials. Overexpression of receptor tyrosine kinases has been reported for TNBC and IBC. Since Grb2 is vital in the cancer signaling of receptor tyrosine kinases, the Company and collaborators at MD Anderson Cancer Center are interested in developing BP1001-A as a potential treatment for TNBC and IBC.

Development and Treatment for Obesity

The disease pathology leading to obesity suggests that BP1001-A has the potential to treat insulin resistance, a major contributor to obesity, Type 2 diabetes and other related metabolic diseases. Patients diagnosed with Type 2 diabetes are at high risk of developing life-threatening co-morbidities and often experience a poor quality of life. Lowering blood glucose levels is the principal goal in the treatment of patients with Type 2 diabetes. One potential method to manage Type 2 diabetes is to reduce body weight. Much success in weight loss has been reported for obese patients who are taking weight loss medication but these medications are not as effective in inducing weight loss in obese patients who have Type 2 diabetes. Therefore, an alternative method of lowering blood glucose level is still needed for obese patients who have Type 2 diabetes.

Insulin lowers blood glucose level by activating the phosphoinositol-3 kinase (PI3K)/AKT pathway. However, this insulin pathway is dysfunctional in obese patients who have Type 2 diabetes. Literature suggests that Grb2 is an inhibitor of the insulin/PI3K/AKT pathway. Upregulation of the Grb2 gene has been reported for patients with Type 2 diabetes. Knockdown of Grb2 expression enhanced insulin-induced AKT activity and glucose uptake in myoblasts and hepatoma cells. Furthermore, insulin sensitivity was restored in Grb2 heterozygous knockout mice fed on high fat-induced diet. We expect that by downregulating Grb2 expression, BP1001-A will lower blood glucose level by enhancing insulin-mediated AKT activation and glucose uptake and storage.

On December 19, 2024, we announced results of our initial preclinical work. BP1001-A, by decreasing Grb2 expression, increased the levels of phosphorylated AKT and phosphorylated FOXO-1 (a downstream AKT effector) in myoblast and hepatoma cells in the presence of insulin. These preliminary data confirmed that BP1001-A affected the insulin/PI3K/AKT pathway and increased insulin sensitivity, thus validating BP1001-A as a potential treatment for obesity in Type 2 diabetes patients. We have initiated animal studies to confirm the efficacy of BP1001-A as a potential treatment for obesity and related metabolic diseases in Type 2 diabetes patients. If successful, we anticipate initiating a first-in-human Phase 1 clinical trial in 2025 to further validate safety, measure pharmacokinetics and establish dosing for potential pivotal trials.

DNABILIZE®

DNAbilize® technology is available for out-licensing. We intend to apply our drug delivery technology template to new disease-causing protein targets to develop new liposomal antisense drug candidates for inclusion in our pipeline that meet scientific, preclinical and commercial criteria and file new patents on these targets. We expect that these efforts will include collaboration with scientific key opinion leaders in the field of study and include developing drug candidates for diseases other than cancer. A significant amount of capital is expected to be allocated to in-license promising protein targets that can be developed as new liposomal antisense drug candidates. As we expand, we will look at indications where a systemic delivery is needed and antisense can be used to slow, reverse or cure a disease, either alone or in combination with another drug. Our patent portfolio currently includes five issued patents in the U.S. that protect the platform technology for DNAbilize®, the Company’s novel RNAi nanoparticle drugs. We plan to continue our efforts to build protection around our technology as it safeguards our platform technology and target-specific technology, is a deterrent to would-be competitors and creates value around our core competencies.

We are interested in pursuing a wide-ranging, proactive licensing program to include co-development of specific liposomal antisense drug candidates, sub-licensing our delivery template for outside development of liposomal antisense drug candidates or out-licensing a partially-developed drug candidate for final development and marketing.

Research and Development

Our research and development expense primarily consists of third-party clinical, preclinical and manufacturing development activities, salaries and benefits expense and stock-based compensation. As we advance and expand our pipeline of drug candidates, we anticipate our research and development expenses will continue to increase in conjunction with these activities. Research and development expenses incurred during the years ended December 31, 2023 and during the nine months ended September 30, 2024 were $11.6 million and $5.5 million, respectively.

Manufacturing

We do not own or operate, and currently have no plans to establish, any manufacturing facilities. Accordingly, we have no ability to internally manufacture the drug candidates that we need to conduct our clinical trials. For the foreseeable future, we expect to continue to rely on third-party manufacturers and other third parties to produce, package and store sufficient quantities of our drug candidates and any future drug candidates for use in our clinical trials. We have entered into agreements with third-party manufacturers for the manufacture of our drug requirements, including agreements for the manufacture of prexigebersen for use in our Phase 2 clinical trial in AML, as well as agreements for the manufacture of BP1002, BP1003 and BP1001-A for use in our Phase 1 clinical trials. However, we may face various risks and uncertainties in connection with our reliance on third-party manufacturers, as discussed in “Risk Factors” of this prospectus under the heading “Risks Related to Manufacturing Our Drug Candidates.” If the FDA or other regulatory agencies approve any of our drug candidates for commercial sale, we expect that we would continue to rely, at least initially, on third-party manufacturers to produce commercial quantities of such approved drug candidates. However, we may in the future elect to manufacture certain of our drug candidates in our own manufacturing facilities. If we do so, we will require substantial additional funds and need to recruit qualified personnel in order to build or lease and operate any manufacturing facilities.

Sales and Marketing

We currently do not have any commercial drug products or an organization for the sales and marketing of pharmaceutical products. In order to successfully commercialize any drug candidates that may be approved in the future by the FDA or comparable foreign regulatory authorities, we must build our sales and marketing capabilities or make arrangements with third parties to perform these services. For certain drug candidates in selected indications where we believe that an approved product could be commercialized by a specialty sales force that calls on a limited but focused group of physicians, we may commercialize these products ourselves. However, in therapeutic indications that require a large sales force selling to a large and diverse prescribing population, we may enter into arrangements with other companies for commercialization.

TABLE OF CONTENTS

If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, we may not be able to generate product revenue and may not become profitable.

Intellectual Property

Patents, trademarks, trade secrets, technology, know-how and other proprietary rights are important to our business. Our success depends in large part on our ability to obtain and maintain patent protection both in the U.S. and in other countries for our drug candidates and on our ability to operate without infringing the proprietary rights of third parties. Our ability to protect our drug candidates from unauthorized or infringing use by third parties depends in substantial part on our ability to obtain and maintain valid and enforceable patents.

We rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. In order to protect our proprietary technology and processes, we also rely in part on confidentiality and intellectual property assignment agreements with our corporate partners, employees, consultants, outside scientific collaborators, sponsored researchers and other advisors. These agreements may not effectively prevent disclosure of confidential information nor result in the effective assignment to us of intellectual property, and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information or other breaches of the agreements. In addition, others may independently discover our trade secrets and proprietary information, and in such case we could not assert any trade secret rights against such party. To the extent that we enter into out-license and in-license agreements in the future, our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for their intellectual property, in particular, any patents to which we secure exclusive rights.

We have expanded our intellectual property portfolio by filing patent applications that are applicable to our technology and business strategy. Our patent portfolio currently includes seven issued patents in the U.S. and sixty-one issued patents in foreign jurisdictions. We have three additional pending patent applications in the U.S. and five additional allowed patent application in a foreign jurisdiction. Further, we have pending patent applications in key foreign jurisdictions across our six families of applications. We continue our efforts to build protection around our technology as it safeguards our platform technology and target-specific technology, is a deterrent to would-be competitors and creates value around our core competencies.

There can be no assurances that patents related to our existing patent applications or applications we may file in the future will be issued or that any issued patents will provide meaningful protection for our drug candidates, which could materially and adversely affect our competitive business position, business prospects and financial condition.

In the U.S., individual patents extend for varying periods of time depending on the date of filing of the patent application or the date of patent issuance. Generally, patents issued in the U.S. are effective for 20 years from the earliest non-provisional filing date. In addition, a patent term can sometimes be extended to recapture a portion of the term effectively lost during the FDA’s regulatory review period; however, the restoration period cannot be longer than five years, and the total patent term cannot exceed 14 years following FDA approval.

Employees

We currently employ ten full-time employees. We also have contractual relationships with additional professionals who perform certain medical officer, regulatory, drug development and administrative duties. We believe relations with such professionals and employees are good.

Competition

TABLE OF CONTENTS

expect to continue to face, intense and increasing competition as new products enter the market and advanced technologies become available. Our competitors may discover, develop or commercialize products or other novel technologies that are more effective, safer or less costly than our drug candidates. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for our drug candidates.

Many of our competitors have:

•

significantly greater capital, technical and human resources than we have and may be better equipped to discover, develop, manufacture and commercialize drug candidates;

•

more experience in drug discovery, development and commercialization, obtaining regulatory approvals and manufacturing and marketing pharmaceutical products;

•

drug candidates that have been approved or are in late-stage clinical development; and/or

•

collaboration arrangements in our target markets with leading companies and research institutions.

Government Regulation

Overview

Government authorities in the U.S., at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, labeling, record keeping, packaging, promotion, storage, advertising, distribution, marketing and export and import of products such as those we are developing. The nature and extent to which such regulations will apply to us will vary depending on the nature of any drug candidates we develop. We anticipate that all of our drug candidates will require regulatory approval by governmental agencies prior to commercialization. This process and subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations will require the expenditure of substantial time and financial resources.

U.S. Drug Development Process

In the U.S., drugs are subject to rigorous regulation by the FDA under the Federal Food, Drug and Cosmetic Act (the “FDCA”), and implementing regulations, as well as other federal and state statutes. Failure by us or our collaborators to comply with the applicable U.S. requirements at any time during the drug candidate development process, approval process or after approval, may subject us to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, license suspension or revocation, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties or criminal prosecution. Any agency or judicial enforcement action could have a material adverse effect on us.

TABLE OF CONTENTS

The process required by the FDA before a new drug may be marketed in the U.S. generally involves the following:

•

completion of preclinical laboratory tests, animal studies and formulation studies according to FDA’s Good Laboratory Practice regulations;

•

submission of an IND, which must become effective before human clinical trials may begin and which must include approval by an institutional review board at each clinical site before the trials are initiated;

•

performance of adequate and well-controlled human clinical trials according to FDA’s Good Clinical Practice (“GCP”) regulations to establish the safety and efficacy of the proposed drug for its intended use;

•

submission to, and acceptance by, the FDA of a new drug application (an “NDA”);

•

completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with current Good Manufacturing Practice (“cGMP”) regulations to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, strength, quality and purity; and

•

FDA review and approval of the NDA.

Pre-Approval Studies

Clinical trials involve the administration of the IND to volunteers or patients under the supervision of one or more qualified investigators in accordance with FDA’s GCP regulations. Clinical trials must be conducted under institutional review board approved protocols detailing the objectives of the trial and the safety and effectiveness criteria to be evaluated. Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if adverse events or other certain types of other changes occur.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

•

Phase 1: The drug candidate is initially introduced into human subjects or patients with the disease and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some drug candidates for severe or life-threatening diseases, the initial human testing is often conducted in patients.

•

Phase 2: Involves studies in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the drug candidate for specific targeted diseases and to determine dosage tolerance and optimal dosage.

•

Phase 3: Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population, typically at geographically dispersed clinical study sites. These studies are intended to establish the overall risk-benefit ratio of the drug candidate and provide, if appropriate, an adequate basis for product labeling.

Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within any specified period, if at all. The FDA or an institutional review board or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug candidate and finalize a process for manufacturing the product in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other requirements, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final drug. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

TABLE OF CONTENTS

Our business model is primarily focused on the preclinical to Phase 2a interval. This greatly reduces the time frame for us from in-license of a new, preclinical stage drug candidate to be developed to out-licensing to a pharmaceutical partner.

Approval Process

After successful completion of the required clinical trials, an NDA is generally submitted, which is required before marketing of the product may begin in the U.S. The NDA must include the results of drug development, preclinical studies and clinical studies, together with other detailed information, including information on the chemistry, manufacture and composition of the drug. Once the submission is accepted for filing, the FDA begins an in-depth substantive review.

The FDA reviews an NDA that has been accepted for filing to determine, among other things, whether a product is safe and effective for its intended use. The approval process for an NDA is lengthy and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require additional clinical or other data and information. Even if such data and information is submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. The FDA may also refer applications for drug candidates which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee. Before approving an NDA, the FDA will also inspect the facility or facilities where the product is manufactured to determine whether its manufacturing is cGMP-compliant to assure and preserve the product’s identity, strength, quality, purity and stability.

There are various programs that are intended to expedite the development and review of drug candidates, and/or provide for approval on the basis of surrogate endpoints, including Fast Track, breakthrough therapy, priority review and accelerated approval. Even if a drug candidate qualifies for one or more of these programs, the FDA may later decide that the drug candidate no longer meets the conditions for qualification or that the time period for FDA review or approval will not be shortened. Generally, drug candidates that may be eligible for these programs are those for serious or life-threatening conditions, those with the potential to address unmet medical needs or those that offer meaningful benefits over existing treatments.

Fast Track is a process designed to facilitate the development and expedite the review of drug candidates to treat serious diseases and fill an unmet medical need. Breakthrough therapy requires preliminary clinical evidence that demonstrates the drug candidate may have substantial improvement on at least one clinically significant endpoint over available therapy. A breakthrough therapy designation conveys all of the Fast Track program features, as well as more intensive FDA guidance on an efficient drug development program. Priority review is designed to give drug candidates that offer major advances in treatment or provide a treatment where no adequate therapy exists an initial review within six months as compared to a standard review time of 10 months. Although Fast Track, breakthrough therapy and priority review do not affect the standards for approval, the FDA will attempt to facilitate early and frequent meetings with a sponsor of a Fast Track designated drug candidate and expedite review of the application for a drug candidate designated for priority review. Accelerated approval provides an earlier approval of drugs to treat serious diseases and that fill an unmet medical need based on a surrogate endpoint, which is a laboratory measurement or physical sign used as an indirect or substitute measurement representing a clinically meaningful outcome. As a condition of approval, the FDA may require that a sponsor of a product receiving accelerated approval perform post-marketing clinical trials.

If the FDA evaluations of the application and the manufacturing facilities are favorable, the FDA may issue an approval letter or an “approvable” letter. An approvable letter will usually contain a number of conditions that must be met in order to secure final approval of the NDA and authorization of commercial marketing of the drug for certain indications. An approval letter authorizes commercial marketing of the drug with specific prescribing information for a specific indication. As a condition of NDA approval, the FDA may require post-approval testing, including Phase 4 trials, and surveillance to monitor the drug’s safety or efficacy and may impose other conditions, including labeling or distribution restrictions which can materially impact the potential market and profitability of the drug. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems occur after the product

TABLE OF CONTENTS

reaches the market. The FDA may also refuse to approve the NDA or issue a “not approvable” letter outlining the deficiencies in the submission and often requiring additional testing or information.

To date, we have not submitted a marketing application for any drug candidate to the FDA or any foreign regulatory agency, and none of our drug candidates have been approved for commercialization in any country. We have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals, including approval by the FDA. The time required to complete clinical trials and for the FDA’s review processes is uncertain and typically takes many years. Our analysis of data obtained from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unanticipated delays or increased costs due to government regulation from future legislation or administrative action or changes in FDA policy during the period of product development, clinical trials, and FDA regulatory review. We estimate that it generally takes 10 to 15 years or possibly longer to discover, develop and bring to market a new pharmaceutical product in the U.S. as outlined below:

Post-Approval Studies

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval. In addition, the FDA may require testing and surveillance programs to monitor the effect of approved products that have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs.

Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things:

•

record-keeping requirements;

•

reporting of adverse experiences with the drug;

•

providing the FDA with updated safety and efficacy information;

•

drug sampling and distribution requirements;

•

notifying the FDA and gaining its approval of specified manufacturing or labeling changes;

•

complying with certain electronic records and signature requirements; and

•

complying with FDA promotion and advertising requirements.

We rely, and expect to continue to rely, on third parties for the production of clinical quantities of our drug candidates. Future FDA and state inspections may identify compliance issues at the facilities of our contract manufacturers that may disrupt production or distribution, or require substantial resources to correct.

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products regulated by the FDA. In addition, FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect our business and our drug candidates. It is impossible to predict whether legislative changes will be enacted, or FDA regulations, guidance or interpretations changed or what the impact of such changes, if any, may be.

Foreign Regulations

Whether or not we obtain FDA approval for a drug candidate, we must obtain the requisite approvals from regulatory authorities in non-U.S. countries prior to the commencement of clinical trials or marketing of our products in those countries. Certain countries outside of the U.S. have a process that requires the submission of a clinical trial application (“CTA”), much like an IND, prior to the commencement of human clinical trials. In the E.U., for example, a CTA must be submitted to the competent national health authority

TABLE OF CONTENTS

and to independent ethics committees in each country in which a company intends to conduct clinical trials. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed in that country.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country, but typically takes several years and requires significant resources. In all cases, the clinical trials must be conducted in accordance with GCP and other applicable regulatory requirements.

Reimbursement

Sales of pharmaceutical products depend in significant part on the availability of third-party reimbursement, which is time consuming and expensive. Reimbursement may not be available or sufficient to allow us to sell our future products, if any, on a competitive and profitable basis.

The passage of the Medicare Prescription Drug and Modernization Act of 2003 (the “MMA”) imposed requirements for the distribution and pricing of prescription drugs for Medicare beneficiaries, which may affect the marketing of our future products, if any. The MMA also introduced a reimbursement methodology, part of which went into effect in 2004, and a prescription drug plan, which went into effect on January 1, 2006. While the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the E.U. provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market.

There have been and we expect that there will continue to be frequent federal and state proposals to impose governmental pricing controls or cost containment measures for prescription drugs. While we cannot predict whether such legislative or regulatory proposals will be adopted, the adoption of such proposals could have a material adverse effect on our business, financial condition and profitability. For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act of 2010, contains provisions that may reduce the profitability of drugs, including, for example, increased rebates for drugs sold to Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to federal health care programs. Even if favorable coverage and reimbursement status is attained for one or more of our drug candidates for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

TABLE OF CONTENTS

Other Regulations

Pursuant to the Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Act, under certain conditions a sponsor may be granted marketing exclusivity for a period of five years following FDA approval. During this period, third parties would not be permitted to obtain FDA approval for a similar or identical drug through an Abbreviated NDA, which is the application form typically used by manufacturers seeking approval of a generic drug. The Hatch-Waxman Act also permits a patent extension term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent extension cannot extend the remaining term of a patent beyond a total of 14 years. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA, plus time of active FDA review between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and it must be applied for prior to expiration of the patent and within 60 days of the approval of the NDA.

In April 2015 and October 2016, prexigebersen received orphan drug designations for AML in the U.S. from the FDA and in the E.U. from the EMA, respectively. Orphan designation is available in the U.S. to drugs intended to treat, diagnose or prevent a rare disease or condition that affects fewer than 200,000 people in the U.S. at the time of application for orphan designation. Orphan drug designation must be requested before submitting an application for marketing authorization. Orphan designation qualifies the sponsor of the product for a tax credit and marketing incentives. The first sponsor to receive FDA marketing approval for a drug with an orphan designation is entitled to a seven-year exclusive marketing period in the U.S. for that product for that indication and, typically, a waiver of the prescription drug user fee for its marketing application. However, a drug that the FDA considers to be clinically superior to, or different from, the approved orphan drug, even though for the same indication, may also obtain approval in the U.S. during the seven-year exclusive marketing period. Orphan drug exclusive marketing rights may also be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug. To receive orphan drug designation from the EMA, a therapy must be intended for the treatment of a life-threatening or chronically debilitating rare condition with a prevalence of less than five in 10,000 in the E.U. Orphan drug designation provides incentives designed to facilitate development, including fee reductions for protocol assistance, scientific advice and importantly, may provide up to ten years of market exclusivity in the E.U. following product approval.

Pharmaceutical companies are also subject to various federal and state laws pertaining to health care “fraud and abuse,” including anti-kickback laws and false claims laws. Anti-kickback laws make it illegal for any entity or person to solicit, offer, receive, or pay any remuneration in exchange for, or to induce, the referral of business, including the purchase or prescription of a particular drug. False claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented, for payment to third party payors, including Medicare and Medicaid, claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services.

Board of Directors

Our operations are managed under the broad supervision of the Board, which has ultimate responsibility for the establishment and implementation of our general operating philosophy, objectives, goals and policies. Our Board is currently comprised of three independent directors and two non-independent directors. The Board has determined that current directors Heath W. Cleaver, Paul D. Aubert and Aline B. Sherwood are “independent” as independence is defined under the listing standards for The Nasdaq Stock Market. The Board based these determinations primarily on a review of the responses our directors provided to questions regarding employment and compensation history, affiliations and family and other relationships.

Codes of Ethics

We have adopted the Employee Code of Business Conduct and Ethics, which applies to all of our employees, including our executive officers, and the Code of Business Conduct and Ethics for Members of the Board, which applies to members of the Board.

Board Committees

The Board has a standing audit committee (the “Audit Committee”), compensation committee (the “Compensation Committee”) and nominating/corporate governance committee (the “Nominating/Corporate Governance Committee”), each of which is governed by a charter. The Board may also establish other committees from time to time as necessary to facilitate the management of the business and affairs

TABLE OF CONTENTS

of the Company. In 2020, the Board formed a business development committee (the “Business Development Committee”) that assists the Board by advising management on its plans for business development, licensing opportunities and business partnership opportunities. In addition to these committees, we also have a Scientific Advisory Board that serves an advisory role to management and the Board. The information below summarizes the functions of each of the committees and the Scientific Advisory Board.

Audit Committee

The Audit Committee has been structured to comply with the requirements of Section 3(a)(58)(A) of the Exchange Act. The Board has determined that the Audit Committee members have the appropriate level of financial understanding and industry specific knowledge to be able to perform the duties of the position and are financially literate and have the requisite financial sophistication as required by the applicable listing standards of The Nasdaq Stock Market.

The Audit Committee, as permitted by, and in accordance with, its charter, is responsible to periodically assess the adequacy of procedures for the public disclosure of financial information and review on behalf of the Board, and report to the Board, the results of its review and its recommendation regarding all material matters of a financial reporting and audit nature, including, but not limited to, the following main subject areas:

•

financial statements, including management’s discussion and analysis thereof;

•

financial information in any annual information form, proxy statement, prospectus or other offering document, material change report, or business acquisition report;

•

press releases regarding annual and interim financial results or containing earnings guidance;

•

internal controls;

•

audits and reviews our financial statements; and

•

filings with securities regulators containing financial information, including our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q.

The Audit Committee appoints and sets the compensation for the independent registered public accounting firm annually and reviews and evaluates such external auditor. This external auditor reports directly to the Audit Committee. The Audit Committee establishes our hiring policies regarding current and former partners and employees of the external auditor. In addition, the Audit Committee pre-approves all audit and non-audit services undertaken by the external auditor.

The Audit Committee has direct responsibility for overseeing the work of the external auditor engaged for the purpose of preparing or issuing an auditor’s report or performing other audit, review or attest services, including the resolution of disagreements between the external auditor and management.

The Audit Committee is currently comprised of Messrs. Cleaver and Aubert and Ms. Sherwood. Mr. Cleaver currently serves as the chair of the Audit Committee. The Board has determined that Mr. Cleaver qualifies as an “audit committee financial expert” under the Exchange Act and that each member of the Audit Committee is an independent director. The Audit Committee meets at least once per fiscal quarter to fulfill its responsibilities under its charter and in connection with the review of the Company’s quarterly and annual financial statements.

Compensation Committee

The Compensation Committee’s role is to assist the Board in fulfilling its responsibilities relating to all forms of compensation of the Company’s executive officers, administering the Company’s incentive compensation plan and other benefits plans, including a deferred compensation plan, if applicable, and producing any required report on executive compensation for use in the Company’s proxy statement or other public disclosure. The Compensation Committee operates under a written charter adopted by the Board. The Compensation Committee periodically assesses compensation of our executive officers in relation to companies of comparable size, industry and complexity, taking the performance of the Company and such other companies into consideration. All decisions with respect to the compensation of our Chief Executive

TABLE OF CONTENTS

Officer are determined and approved either solely by the Compensation Committee or together with other independent directors, as directed by the Board. All decisions with respect to non-CEO executive compensation, and incentive-compensation and equity-based plans are first approved by the Compensation Committee and then submitted, together with the Compensation Committee’s recommendation, to the members of the Board for final approval. In addition, the Compensation Committee will, as appropriate, review and approve public or regulatory disclosure respecting compensation, including required disclosures regarding executive compensation under Item 402 of Regulation S-K, and the basis on which performance is measured. The Compensation Committee has the authority to retain and compensate any outside adviser as it determines necessary to permit it to carry out its duties. The Compensation Committee has not to date engaged the services of any executive compensation consultant. The Compensation Committee may not form or delegate authority to subcommittees without the prior approval of the Board.

The Compensation Committee is currently comprised of Messrs. Aubert and Cleaver and Ms. Sherwood, each of whom are independent under the rules of The Nasdaq Stock Market. The Compensation Committee meets as necessary. Mr. Aubert currently serves as the chair of the Compensation Committee.

Nominating/Corporate Governance Committee

The Nominating/Corporate Governance Committee’s charter provides that the responsibilities of such committee include:

•

evaluating, identifying and recommending nominees to the Board;

•

considering written recommendations from our stockholders for nominees to the Board;

•

recommending directors to serve as committee members and chairs;

•

reviewing and developing corporate governance guidelines, policies and procedures for the Board;

•

reviewing disclosure by the Company of matters within the Nominating/Corporate Governance Committee’s mandate; and

•

reviewing and evaluating the Nominating/Corporate Governance Committee’s charter and efficacy.

The Nominating/Corporate Governance Committee is responsible for, among other things, identifying and recommending potential candidates for nomination to the Board. The Nominating/Corporate Governance Committee receives advice from the Board and will consider written recommendations from the stockholders of the Company respecting individuals best suited to serve as directors, and, when necessary, develops its own list of appropriate candidates for directorships. For a description of the procedures to be followed by stockholders of the Company in submitting recommendations to be considered by the Nominating/Corporate Governance Committee, see the discussion set forth below under the heading titled, “Stockholder Nominations for Directors.”

The Nominating/Corporate Governance Committee is currently comprised of Messrs. Cleaver and Aubert and Ms. Sherwood, each of whom are independent under the rules of The Nasdaq Stock Market. Mr. Cleaver currently serves as the chair of the Nominating/Corporate Governance Committee. The Nominating/Corporate Governance Committee meets at least annually, and otherwise as necessary.

Business Development Committee

The Business Development Committee also performs other duties as directed by the Board from time to time and operates under a written charter adopted by the Board. The Business Development Committee is currently comprised of Ms. Sherwood and Messrs. Nielsen and Morris. Ms. Sherwood currently serves as the chair of the Business Development Committee.

Scientific Advisory Board

manufacture, use and/or sale of our drug candidates and products. The Scientific Advisory Board meets on an ad hoc basis and may attend meetings of the Board at the Board’s request. The current members of the Scientific Advisory Board are Jorge Cortes, M.D, who serves as chairman, D. Craig Hooper, Ph.D., and Jason Fleming, M.D.

Availability of Committee Charters and Other Information

The charters for our Audit Committee, Compensation Committee, and Nominating/Corporate Governance Committee, as well as our Corporate Governance Guidelines, Employee Code of Business Conduct and Ethics and Code of Business Conduct and Ethics for Members of the Board, are available under the section titled “Corporate Governance” on the Investors page of the Company’s website, www.biopathholdings.com. We intend to disclose any changes to or waivers from the Employee Code of Business Conduct and Ethics that would otherwise be required to be disclosed under Item 5.05 of Form 8-K on our website. The information on our website is not, and shall not be deemed to be, a part of this prospectus or incorporated into any other filings we make with the SEC.

We also make available on our website, free of charge, access to our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and any amendments to those reports, as well as other documents that we file with or furnish to the SEC pursuant to Sections 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after such documents are filed with, or furnished to, the SEC.

Nomination Process

It is our Board’s responsibility to nominate members for election to the Board and to fill vacancies on the Board that may occur between annual meetings of stockholders. The Nominating/Corporate Governance Committee assists the Board by identifying and reviewing potential candidates for Board membership consistent with criteria approved by the Board. The Nominating/Corporate Governance Committee also annually recommends qualified candidates (which may include existing directors) for approval by the Board of a slate of nominees to be proposed for election to the Board at the annual meeting of stockholders.

In the event of a vacancy on the Board between annual meetings of our stockholders, the Board may request that the Nominating/Corporate Governance Committee identify, review and recommend qualified candidates for Board membership for Board consideration to fill such vacancies, if the Board determines that such vacancies will be filled. Our First Amended and Restated Bylaws (as amended, the “Bylaws”) allow for up to fifteen directors. The Board is permitted by the Bylaws to change the number of directors by a resolution adopted by the Board.

When formulating its recommendations for potential Board nominees, the Nominating/Corporate Governance Committee seeks and considers advice and recommendations from management, other members of the Board and may seek or consider advice and recommendations from consultants, outside counsel, accountants or other advisors as the Nominating/Corporate Governance committee or the Board may deem appropriate.

Board membership criteria are determined by the Board, with input from the Nominating/Corporate Governance Committee. The Board is responsible for periodically determining the appropriate skills, perspectives, experiences and characteristics required of Board candidates, taking into account our needs and current make-up of the Board. This assessment should include appropriate knowledge, experience, and skills in areas deemed critical to understanding the Company and our business; personal characteristics, such as integrity and judgment; and the candidate’s commitments to the boards of other companies. Each Board member is expected to ensure that other existing and planned future commitments do not materially interfere with the member’s service as a director and that he or she devotes the time necessary to discharge his or her duties as a director.

Stockholder Nominations for Directors

The Nominating/Corporate Governance Committee will consider candidates for director nominees that are recommended by our stockholders in the same manner as Board recommended nominees, in

TABLE OF CONTENTS

accordance with the procedures set forth in our Bylaws. Any such nominations should be submitted to the Nominating/Corporate Governance Committee c/o Secretary, Bio-Path Holdings, Inc., 4710 Bellaire Boulevard, Suite 210, Bellaire, Texas 77401 before the deadline set forth in the Bylaws and should be accompanied by the following information:

•

appropriate biographical information, a statement as to the qualifications of the nominee and any other information relating to such nominee that is required to be disclosed pursuant to Regulation 14A under the Exchange Act (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); and

•

the Proposing Stockholder Information (as defined in the Bylaws).

Involvement in Certain Legal Proceedings

There have been no events under any bankruptcy act, no criminal proceedings and any judgments or injunctions material to the evaluation of the ability and integrity of any director or executive officer during the last ten years.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and officers, and persons who own more than 10% of our common stock, to file initial reports of ownership and reports of changes in ownership (Forms 3, 4, and 5) of common stock with the SEC. Officers, directors and greater than 10% stockholders are required by SEC regulation to furnish us with copies of all such forms that they file.

To our knowledge, based solely on our review of the copies of such reports received by us and on written representations by certain reporting persons that no reports on Form 5 were required, we believe that during the fiscal year ended December 31, 2023, all Section 16(a) filing requirements applicable to our officers, directors and 10% stockholders were complied with in a timely manner.

EXECUTIVE COMPENSATION

The compensation committee of our board of directors (the “Compensation Committee”) oversees our compensation programs for executives and all employees. The Compensation Committee understands that for the Company and its stockholders to achieve long-term success, the compensation programs need to attract, retain, develop and motivate a strong leadership team. As a result, our executive compensation programs are designed to pay for performance, enable talent attraction, retain top talent and closely align the interests of our executives with those of our stockholders. All decisions with respect to the compensation of our Chief Executive Officer are determined and approved either solely by the Compensation Committee or together with other independent directors, as directed by our board of directors. All decisions with respect to non-CEO executive compensation, incentive-compensation and equity-based plans are first approved by the Compensation Committee and then submitted, together with the Compensation Committee’s recommendation, to the members of our board of directors for final approval.

This section provides important information on our executive compensation programs and explains the compensation decisions made during 2024 by the Compensation Committee for our named executive officers (“NEOs”). In the fiscal year ended December 31, 2024, our only NEO was Peter H. Nielsen, Chairman of the Board, Chief Executive Officer, Chief Financial Officer and President.

Compensation Philosophy

Our primary objective with respect to executive compensation is to design a reward system that will align executive compensation with our overall business strategies and attract and retain highly qualified executives. We intend to stay competitive in the marketplace with companies of comparable size, industry and complexity. Our compensation philosophy for executives is guided by the following principles:

•

Pay for Performance. In making compensation decisions, we consider annual and long-term Company performance and consider the compensation of our executive officers in relation to companies of comparable size, industry and complexity, taking the performance of the Company into consideration.

•

Reviewed Annually. The Compensation Committee annually reviews compensation levels to ensure we remain competitive and continue to attract, retain and motivate top-tier talent.

•

Alignment with Stockholder Interests. Our compensation is intended to closely align the interests of our NEOs with those of our stockholders in an effort to create long-term stockholder value. In developing our compensation philosophy, the Compensation Committee has considered the most recent stockholder advisory vote on executive compensation in which an overwhelmingly positive percentage of the votes cast were in favor of our executive compensation. The Compensation Committee is continuously mindful of stockholders’ views on executive compensation and remains focused on ensuring proper alignment with stockholder interests.

Our compensation philosophy rewards demonstrated performance and encourages behavior that is in the long-term best interests of the Company and its stockholders.

Elements and Mix of our 2024 Compensation Program

The following elements made up the fiscal year 2024 compensation program for our NEOs:

Element			Form of Compensation			Purpose, Basis and Performance Criteria
Base Salary			Cash			• Base salary is intended to provide a market competitive level of fixed compensation in recognition of responsibilities, skills, capabilities, experience and leadership. • Base salary is not generally performance based, but reflective of competencies and experience.

TABLE OF CONTENTS

Element	Form of Compensation	Purpose, Basis and Performance Criteria
Annual Performance Incentive Awards (considered “at-risk” compensation)	Cash	• Annual cash performance incentive awards are intended to motivate and reward performance achievement. • Payments are discretionary and approved annually by the Compensation Committee.
Long-Term Incentive Awards (considered “at-risk” compensation)	Stock Options	• Long-term incentive awards are intended to recognize and reward the achievement of long-term corporate goals and objectives, recognize promotions, motivate retention of our leadership talent and align executives’ interests with our stockholders. • The Compensation Committee determines the amount of long-term incentive awards to be granted to each NEO. The Compensation Committee also may make isolated awards to recognize promotions, new hires or individual performance achievements. • In 2024, the long-term incentive awards included time-vested equity awards that vest over a four- year period. • The Compensation Committee provides time-vested long-term incentives (i) to build a consistent ownership stake and retention incentive, (ii) to create a meaningful tie to the Company’s relative long-term stockholder returns and (iii) to motivate consistent improvement over a longer-term horizon.
Change of Control Severance	Eligible to receive severance payments and post-termination health benefits in connection with involuntary termination within three months before or twelve months after a change of control	• Employment agreements are intended to provide financial security and an industry-competitive compensation package for NEOs. This additional security helps ensure that NEOs remain focused on our performance and the continued creation of stockholder value throughout any change of control transaction rather than on the potential uncertainties associated with their own employment.

Evaluation Process, Compensation Consultant, Peer Comparisons and Officers

Evaluation Process. The Compensation Committee oversees the administration of the compensation programs applicable to our employees, including our NEOs. The Compensation Committee generally makes its decisions regarding the annual compensation of our NEOs at its regularly-scheduled meeting in the first quarter of each year. These decisions include adjustments to base salary, grants of annual incentive awards and grants of long-term incentive awards. The Compensation Committee also makes compensation adjustments as necessary at other times during the year, such as in the case of promotions, changes in employment status and for competitive purposes.

Each year for the Compensation Committee meeting, our CEO prepares an evaluation of each of the other executive officers, if any, and makes compensation recommendations to the Compensation Committee based upon our performance against our corporate performance metrics and the individual’s performance. In addition to considering the CEO’s recommendations, the Compensation Committee assesses the applicable

TABLE OF CONTENTS

executive officer’s impact during the year and his or her overall value to the Company, specifically by considering the individual leadership skills, impact on strategic initiatives, performance in his or her primary area of responsibility, his or her role in succession planning and development, and other intangible qualities that contribute to corporate and individual success. During 2024, our CEO was our only executive officer.

Compensation Consultant and Peer Comparisons. For the 2024 performance period, the Compensation Committee did not engage an external compensation consultant to review the compensation of our executive officers. For comparison purposes, the Compensation Committee relied upon peer executive compensation data from proxies and compensation surveys of the Industry Peer Group (as defined below) prepared by our executive compensation counsel based on parameters set by the Compensation Committee. The Compensation Committee reviewed executive compensation data from the Industry Peer Group to consider competitive pay levels and compensation practices. Such data included components such as total direct compensation, considered as the sum of base salary and annual cash performance incentive award, as well as total compensation, including long-term incentive awards.

While executive compensation data from the Industry Peer Group provides a point of reference for measurement, it is not the determinative factor for compensation decisions. The Compensation Committee does not target the compensation of our executive officers to a specific percentile of compensation provided to officers in comparable positions in our Industry Peer Group. The purpose of the comparison is not to supplant the analyses of our corporate performance and the individual performance of our executive officers that the Compensation Committee considers when making compensation decisions. Because the compensation data is just one of the several analytic tools that are used in setting executive compensation, the Compensation Committee has discretion in determining the nature and extent of its use.

The Compensation Committee established our current Industry Peer Group in 2024. With the assistance of our executive compensation counsel, the Compensation Committee reviews the composition of the peer group annually to ensure that companies are relevant for comparative purposes. In identifying companies to include in the Industry Peer Group, the Compensation Committee considered, among other things, the following:

•

the industry of the companies;

•

the annual revenue, market capitalization and total assets of the companies;

•

the number of full-time employees of the companies;

•

the market data sources that are available with respect to the companies; and

•

the number of peers included in the Industry Peer Group.

For 2024, our Industry Peer Group consisted of the following companies (the “Industry Peer Group”):

•

CNS Pharmaceuticals, Inc. (CNSP)

•

Cyclacel Pharmaceuticals Inc. (CYCC)

•

Kintara Therapeutics, Inc. (KTRA)

•

Monopar Therapeutics, Inc. (MNPR)

•

Neurobo Therapeutics Inc. (NRBO)

•

Onconova Therapeutics, Inc. (ONTX)

•

Panbela Therapeutics, Inc. (PBLA)

•

Soligenix, Inc. (SNGX)

•

Sonnet Biotherapeutics Holdings, Inc. (SONN)

•

Xenetic Biosciences Inc. (XBIO)

TABLE OF CONTENTS

Role of the Chief Executive Officer. Annually, our CEO provides the Compensation Committee with an evaluation of his performance that is based, in large part, upon performance of the Company and as our lead representative to the investment community. The Compensation Committee evaluates our CEO on these and other criteria. The total compensation package for our CEO is based on the Compensation Committee’s evaluation, and reflects his performance, the performance of the Company and competitive industry practices.

Role of Other Executive Officers. Our CEO makes recommendations to the Compensation Committee on all compensation actions (other than his own compensation) affecting our other executive officers, if any. In developing his recommendation for an executive officer, our CEO considers the self-evaluation prepared by the executive officer, the recommendations of his executive team, as well as his own evaluation. Our CEO’s evaluation includes an assessment of the impact that the executive officer has had on the Company during the award year and their overall value to the Company as a senior leader. The Compensation Committee is provided with our CEO’s evaluation of each executive officer’s performance and contributions to the Company. The Compensation Committee considers the information and recommendations provided by our CEO and provides a recommendation to our board of directors for non-CEO executive officer base salary, annual cash incentive awards and grants of long-term incentive awards, which are subject to approval by our board of directors. During 2024, our CEO was our only executive officer.

2024 Performance Analysis and Compensation Decisions

In its meeting in the first quarter of each year, the Compensation Committee determines base salaries for the current year, the annual performance incentive awards for prior-year performance and the long-term incentive awards for the current year. Each element is reviewed annually, as well as at the time of a promotion, other change in responsibilities, other significant corporate events or a material change in market conditions. Variances in the amount of compensation awarded to each executive officer generally reflect differences in individual responsibility and experience.

Base Salary. During 2024, the Compensation Committee approved an annual base salary for Mr. Nielsen of $440,000, compared to $400,000 during 2023 (Mr. Nielsen voluntarily reduced his base salary for 2023 from $575,000 to $400,000).

Annual Performance Incentive Awards. During 2024, the Compensation Committee approved a discretionary annual cash performance incentive award for Mr. Nielsen in the amount of $150,000.

Long-term Incentive Awards. The Compensation Committee believes that long-term incentive awards should provide for a retention incentive with a strong tie to relative long-term stockholder return. Accordingly, the Compensation Committee grants stock option awards that typically vest over a four-year period. During 2024, the Board approved a long-term incentive award in the form of stock options to Mr. Nielsen based on recommendations from the Compensation Committee. Specifically, in July 2024, Mr. Nielsen was awarded a time-vested stock option award to purchase 25,000 shares of our common stock. The terms of the stock option grant require, among other things, that Mr. Nielsen continue to provide services over the vesting period of the options. The stock options vest over a four-year period from the date of the grant, with one-fourth (1/4) of the stock options vesting on the first anniversary of such grant, and the remaining stock options vesting thereafter in equal monthly increments equal to one-forty-eighth (1/48) of the stock options over the next three years, based on continuing service to the Company.

be paid to the extent not yet paid; (ii) the equivalent of Mr. Nielsen’s base salary will be paid for a period of three months; and (iii) subject to certain restrictions, for three months after Mr. Nielsen’s date of termination, the Company will continue its contributions toward Mr. Nielsen’s health care, dental, disability and life insurance benefits on the same basis as immediately prior to the date of termination.

The severance payments and benefits include the following in the event Mr. Nielsen is terminated without Cause or resigns for Good Reason within three months before or 12 months following a Change in Control: (i) any unvested stock or stock options awarded to Mr. Nielsen shall immediately vest upon the occurrence of Mr. Nielsen’s termination of employment; (ii) Mr. Nielsen’s base salary will be paid through the termination date, and any accrued but untaken vacation days of Mr. Nielsen will be paid to the extent not yet paid; (iii) Mr. Nielsen’s normal post-termination benefits will be paid in accordance with our retirement, insurance and other benefit plan arrangements (including non-qualified deferred compensation plans); (iv) the equivalent of Mr. Nielsen’s base salary will be paid for a period of three months; (v) subject to certain restrictions, for six months after Mr. Nielsen’s date of termination, or such longer period as may be provided by the terms of the appropriate plan, program, practice of policy, Mr. Nielsen’s health care, dental, disability and life insurance benefits will be provided on the same basis as immediately prior to the date of termination; and (vi) subject to certain restrictions and to the extent not otherwise paid or provided, we will pay or provide any other amounts or benefits required to be paid or provided or which Mr. Nielsen is eligible to receive following his termination of employment under any of our plans, programs, policies, practices, contracts or agreements.

Potential severance payments and benefits to be paid pursuant to the Nielsen Employment Agreement assuming a termination or Change in Control occurred on December 31, 2024 are set forth in the table below.

Name	Benefit	Triggering Event
Name	Benefit	Termination without Cause or Resignation for Good Reason ($)			Termination without Cause or Resignation for Good Reason within 3 Months Before or 12 Months Following a Change in Control ($)
Peter H. Nielsen	Market Value of Stock Vesting		$	—		$	—(1)
	Accrued Vacation Days			40,615			40,615
	Three Months’ Base Salary			110,000			110,000
	Continuation of Benefits			4,354			8,709
	Total		$	154,969		$	159,324

Mr. Nielsen’s stock option awards would immediately become vested, and the value of the acceleration would be equal to the vesting shares multiplied by the excess of the then current stock price over the exercise price of the options. For purposes of this table, we have calculated the value of the acceleration using the closing price of our common stock on December 31, 2024, or $1.16 per share.

Non-employee directors received as compensation an annual cash retainer in the amount of $40,000.

The chairs of the respective board committees also received as compensation the following amounts: (i) an annual cash retainer in the amount of $20,000 to the chair of the Audit Committee; (ii) an annual cash retainer in the amount of $10,000 to the chair of the Compensation Committee; (iii) an annual cash retainer in the amount of $8,000 to the chair of the Nominating/Corporate Governance Committee; and (iv) an annual cash retainer in the amount of $8,000 to the chair of the Business Development Committee.

Equity Compensation Program

Each non-employee director of the board also received as compensation an annual stock option grant (a “Grant”) of 2,000 shares of our common stock (the “Option Shares”).

Related Party Transactions

It is our policy that we will not enter into any transactions required to be disclosed under Item 404 of Regulation S-K promulgated by the SEC unless the Audit Committee first reviews and approves the transactions. The Audit Committee is required to review on an ongoing basis, and pre-approve all related party transactions before they are entered into, including those transactions that are required to be disclosed under Item 404 of Regulation S-K. Related party transactions involving a director must also be approved by the disinterested members of the Audit Committee. It is the responsibility of our employees and directors to disclose any significant financial interest in a transaction between the Company and a third party, including an indirect interest. All related party transactions shall be disclosed in our filings with the SEC as required under SEC rules.

In addition, pursuant to our codes of ethics, all employees, officers and directors of ours and our subsidiaries are prohibited from engaging in any relationship or financial interest that is an actual or potential conflict of interest with us without approval. Employees and officers are required to provide written disclosure to their supervisors as soon as they have any knowledge of a transaction or proposed transaction with an outside individual, business or other organization that would create a conflict of interest or the appearance of one. Directors are required to disclose such information to the Board or as otherwise required by law.

For our last two fiscal years, there has not been nor is there currently proposed any transaction or series of similar transactions to which we were or are to be a party in which the amount involved exceeds the lesser of $120,000 or 1% of the average of our total assets at the end of our last two fiscal years, and in which any of our directors, executive officers, persons who we know hold more than 5% of our common stock, or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest other than: (i) compensation agreements and other arrangements, which are described elsewhere in this prospectus and (ii) the transactions described in the following paragraph.

We have entered into indemnity agreements with certain of our officers and directors which provide, among other things, that we will indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under applicable law, our Certificate of Incorporation and our Bylaws.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

The following description of our common stock and preferred stock is a summary. It is not complete and is subject to and qualified in its entirety by our certificate of incorporation and first amended and restated bylaws, as amended. See the section titled “Where You Can Find More Information.” As of the date of this prospectus, our certificate of incorporation authorizes us to issue 200,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.001 per share. As of January 15, 2025, there were 5,767,892 shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding.

Common Stock

Holders of common stock are entitled to one vote for each share held in the election of directors and on all other matters submitted to a vote of stockholders. Cumulative voting of shares of common stock is prohibited. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election.

Subject to the prior rights of the holders of any outstanding preferred stock, holders of common stock are entitled to receive dividends when, as and if declared by our board of directors out of funds legally available therefor. Upon the liquidation, dissolution or winding up of our company, the holders of common stock are entitled to receive ratably the assets of our company remaining after payment of all liabilities and payment to holders of preferred stock if such preferred stock has an involuntary liquidation preference over the common stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. The outstanding shares of common stock are, and the shares offered by us in this offering will be, when issued and paid for, validly issued, fully paid and nonassessable.

As of January 2, 2025, there were approximately 197 holders of record of our common stock.

Preferred Stock

The board of directors is authorized, without any further notice to or action of the stockholders, to issue 10,000,000 shares of preferred stock in one or more series and to determine the relative rights, preferences and privileges of the shares of any such series.

Limitation on Liability and Indemnification of Officers and Directors

Our certificate of incorporation and first amended and restated bylaws, as amended, provide for indemnification of our officers and directors to the fullest extent permitted by Delaware law. Our certificate of incorporation and first amended and restated bylaws, as amended, limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. We maintain directors’ and officers’ liability insurance.

Anti-Takeover Effects of Provisions of Our Certificate of Incorporation, Our Bylaws and Delaware Law

Some provisions of Delaware law and our certificate of incorporation and our first amended and restated bylaws, as amended, contain provisions that could have the effect of delaying, deterring or preventing another party from acquiring or seeking to acquire control of us. These provisions are intended to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage anyone seeking to acquire control of us to negotiate first with our board of directors. However, these provisions may also delay, deter or prevent a change in control or other takeover of our company that our stockholders might consider to be in their best interests, including transactions that might result in a premium being paid over the market price of our common stock and also may limit the price that investors are willing to pay in the future for our common stock. These provisions may also have the effect of preventing changes in our management.

Our certificate of incorporation and first amended and restated bylaws, as amended, include anti-takeover provisions that:

•

authorize our board of directors, without further action by the stockholders, to issue shares of preferred stock in one or more series, and with respect to each series, to fix the number of shares constituting that series and establish the rights and other terms of that series;

TABLE OF CONTENTS

•

establish advance notice procedures for stockholders to submit nominations of candidates for election to our board of directors and other proposals to be brought before a stockholders meeting;

•

provide that our first amended and restated bylaws, as amended, may be amended by our board of directors without stockholder approval;

•

limit our stockholders’ ability to call special meetings of stockholders;

•

allow our directors to establish the size of the board of directors by action of the board, subject to a minimum of three members;

•

provide that vacancies on our board of directors or newly created directorships resulting from an increase in the number of our directors may be filled only by a majority of directors then in office, even though less than a quorum; and

•

do not give the holders of our common stock cumulative voting rights with respect to the election of directors.

Business Combinations

Section 203 of the Delaware General Corporation Law provides that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the person became an interested stockholder, unless:

•

prior to the time that person became an interested stockholder, our board of directors approved either the business combination or the transaction which resulted in the person becoming an interested stockholder;

•

upon consummation of the transaction which resulted in the person becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding certain shares; or

•

at or subsequent to the time the person became an interested stockholder, the business combination is approved by the board of directors and by the affirmative vote of at least 662∕3% of the outstanding voting stock which is not owned by the interested stockholder.

Generally, a business combination includes a merger, consolidation, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an interested stockholder is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our voting stock. The statute could prohibit or delay mergers or other takeover or change in control attempts with respect to us and, accordingly, may discourage attempts to acquire us.

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering up to 13,003,901 shares of our common stock and Common Warrants to purchase up to 39,011,703 shares of our common stock. In addition, we are also offering Pre-Funded Warrants in lieu of shares of common stock to those investors whose purchase of shares of our common stock in this offering would result in the investor, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the investor, 9.99%) of our outstanding common stock following the consummation of this offering. For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. We are also offering the shares of common stock issuable from time to time upon exercise of the Pre-Funded Warrants and the Common Warrants offered hereby.

Common Stock

The material terms and provisions of our common stock are described under the heading “Description of Capital Stock” in this prospectus.

Pre-Funded Warrants

The following summary of certain terms and provisions of Pre-Funded Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Pre-Funded Warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-Funded Warrant for a complete description of the terms and conditions of the Pre-Funded Warrants.

Duration, Exercise Price and Form. Each Pre-Funded Warrant offered hereby will have an initial exercise price per share equal to $0.001. The Pre-Funded Warrants will be immediately exercisable and may be exercised at any time until the Pre-Funded Warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Pre-Funded Warrants will be issued separately from the accompanying Common Warrants and may be transferred separately immediately thereafter. The Pre-Funded Warrants will be issued in certificated form only.

Exercisability. The Pre-Funded Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). Purchasers of the Pre-Funded Warrants in this offering may elect to deliver their exercise notice following the pricing of the offering and prior to the issuance of the Pre-Funded Warrants at closing to have their Pre-Funded Warrants exercised immediately upon issuance and receive shares of common stock underlying the Pre-Funded Warrants upon closing of this offering. A holder (together with its affiliates) may not exercise any portion of the Pre-Funded Warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s Pre-Funded Warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrants. Purchasers of Pre-Funded Warrants in this offering may also elect prior to the issuance of the Pre-Funded Warrants to have the initial exercise limitation set at 9.99% of our outstanding common stock.

Fractional Shares. No fractional shares of common stock will be issued in connection with the exercise of a Pre-Funded Warrant. In lieu of fractional shares, we will either round up to the nearest whole number or pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

101

TABLE OF CONTENTS

Cashless Exercise. If, at the time a holder exercises its Pre-Funded Warrants, in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Pre-Funded Warrants.

Transferability. Subject to applicable laws, a Pre-Funded Warrant may be transferred at the option of the holder upon surrender of the Pre-Funded Warrant to us together with the appropriate instruments of transfer.

Exchange Listing. There is no trading market available for the Pre-Funded Warrants on any securities exchange or nationally recognized trading system. We do not intend to list the Pre-Funded Warrants on any securities exchange or nationally recognized trading system.

Right as a Stockholder. Except as otherwise provided in the Pre-Funded Warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the Pre-Funded Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their Pre-Funded Warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the Pre-Funded Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of 50% or more of our outstanding common stock, or any person or group becoming the beneficial owner of 50% or more of the voting power represented by our outstanding common stock, the holders of the Pre-Funded Warrants will be entitled to receive upon exercise of the Pre-Funded Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Pre-Funded Warrants immediately prior to such fundamental transaction.

Common Warrants

The following summary of certain terms and provisions of Common Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Common Warrants, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part.

We intend to promptly, and in no event later than ninety (90) days after the consummation of this offering, seek the Warrant Stockholder Approval for the issuance of shares of common stock issuable upon exercise of the Series A Warrants but we cannot assure you that the Warrant Stockholder Approval will be obtained, provided, however, that if and only if the Pricing Conditions are met, then we will not seek Warrant Stockholder Approval.

every ninety (90) days thereafter until the earlier of the date we obtain such approval or the Series A Warrants are no longer outstanding.

Exercisability.

No Series A Warrants exercisable for a fractional share will be issued in this offering.

Cashless Exercise. If, at the time a holder exercises its Series A Warrants, a registration statement registering the issuance of the shares of common stock underlying the Series A Warrants under the Securities Act is not then effective or available and an exemption from registration under the Securities Act is not available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Series A Warrants.

Fractional Shares. No fractional shares of common stock will be issued upon the exercise of the Series A Warrants. In lieu of fractional shares, we will either round up to the nearest whole number or pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Transferability. Subject to applicable laws, a Series A Warrant may be transferred at the option of the holder upon surrender of the Series A Warrants to us together with the appropriate instrument of transfer.

Exchange Listing. There is no established public trading market for the Series A Warrants, and we do not expect a market to develop. In addition, we do not intend to list the Series A Warrants on any securities exchange or nationally recognized trading system. Without an active trading market, the liquidity of the Series A Warrants will be limited.

Right as a Stockholder. Except as otherwise provided in the Series A Warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the Series A Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their Series A Warrants.

In addition, in certain circumstances, upon a fundamental transaction, the holder of a Series A Warrant will have the right to require us to repurchase its Series A Warrants at the Black-Scholes value; provided, however, that, if the fundamental transaction is not within our control, including not approved by our board of directors, then the holder will only be entitled to receive the same type or form of consideration (and in the same proportion), at the Black-Scholes value of the unexercised portion of the Series A Warrant that is being offered and paid to the holders of our common stock in connection with the fundamental transaction.

If, at the time a holder exercises its Series B Warrants, a registration statement registering the issuance of the shares of common stock underlying the Series B Warrants under the Securities Act is not then effective or available and an exemption from registration under the Securities Act is not available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Series B Warrants.

Fractional Shares. No fractional shares of common stock will be issued upon the exercise of the Series B Warrants. In lieu of fractional shares, we will either round up to the nearest whole number or pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Transferability. Subject to applicable laws, a Series B Warrant may be transferred at the option of the holder upon surrender of the Series B Warrants to us together with the appropriate instrument of transfer.

Exchange Listing. There is no established public trading market for the Series B Warrants, and we do not expect a market to develop. In addition, we do not intend to list the Series B Warrants on any securities exchange or nationally recognized trading system. Without an active trading market, the liquidity of the Series B Warrants will be limited.

TABLE OF CONTENTS

Right as a Stockholder. Except as otherwise provided in the Series B Warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the Series B Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their Series B Warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the form of Series B Warrant, and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of greater than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of greater than 50% of the voting power represented by our outstanding common stock, the holders of the Series B Warrants will be entitled to receive upon exercise of the Series B Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Series B Warrants immediately prior to such fundamental transaction. In addition, in certain circumstances, upon a fundamental transaction, the holder of a Series B Warrant will have the right to require us to repurchase its Series B Warrants at the Black-Scholes value; provided, however, that, if the fundamental transaction is not within our control, including not approved by our board of directors, then the holder will only be entitled to receive the same type or form of consideration (and in the same proportion), at the Black-Scholes value of the unexercised portion of the Series B Warrant that is being offered and paid to the holders of our common stock in connection with the fundamental transaction.

Series C Warrants

Duration, Exercise Price and Form. Each Series C Warrant offered hereby will have an initial exercise price per share equal to $ . The Series C Warrants will be exercisable on the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series C Warrants will be immediately exercisable. The Series C Warrants will expire nine months from the Warrant Stockholder Approval Date, provided that if the Pricing Conditions are met, the Series C Warrants will expire nine months from the date of issuance. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Series C Warrants will be issued separately from the common stock or Pre-Funded Warrants, as applicable, and will be held separately immediately thereafter. A Series C Warrant to purchase one share of our common stock will be issued for every share of common stock or Pre-Funded Warrant purchased in this offering. The Series C Warrants will be issued in certificated form only.

We intend to promptly, and in no event later than ninety (90) days after the consummation of this offering, seek the Warrant Stockholder Approval for the issuance of shares of common stock issuable upon exercise of the Series C Warrants but we cannot assure you that the Warrant Stockholder Approval will be obtained, provided, however, that if and only if the Pricing Conditions are met, then we will not seek Warrant Stockholder Approval. We have agreed with the investors in this offering that, if we do not obtain stockholder approval for the issuance of the shares of common stock upon exercise of the Series C Warrants at the first stockholder meeting for such purpose after this offering, we will call a stockholder meeting every ninety (90) days thereafter until the earlier of the date we obtain such approval or the Series C Warrants are no longer outstanding.

Exercisability. The Series C Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Series C Warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s Series C Warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Series C Warrants. No Series C Warrants exercisable for a fractional share will be issued in this offering.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

Pursuant to an engagement agreement, (as amended, the “Engagement Letter”), we have engaged , to act as our exclusive placement agent to solicit offers to purchase the securities offered pursuant to this prospectus on a reasonable best efforts basis. The engagement agreement does not give rise to any commitment by the Placement Agent to purchase any of our securities, and the Placement Agent will have no authority to bind us by virtue of the engagement agreement. The Placement Agent is not purchasing or selling any of the securities offered by us under this prospectus, nor is it required to arrange for the purchase or sale of any specific number or dollar amount of securities. This is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering. The Placement Agent has agreed to use reasonable best efforts to arrange for the sale of the securities by us. Therefore, we may not sell all of the shares of common stock, Pre-Funded Warrants and Common Warrants being offered. The terms of this offering are subject to market conditions and negotiations between us, the Placement Agent and prospective investors. The Placement Agent does not guarantee that it will be able to raise new capital in any prospective offering. The Placement Agent may engage sub-agents or selected dealers to assist with the offering.

Investors purchasing securities offered hereby will have the option to execute a securities purchase agreement with us. In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers which enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract is material to larger purchasers in this offering as a means to enforce the following covenants uniquely available to them under the securities purchase agreement: (i) a covenant to not enter into variable rate financings for a period of one year following the closing of the offering, subject to certain exceptions; and (ii) a covenant to not enter into any equity financings for seventy-five days from closing of the offering, subject to certain exceptions. The nature of the representations, warranties and covenants in the securities purchase agreements shall include:

•

standard issuer representations and warranties on matters such as organization, qualification, authorization, no conflict, no governmental filings required, current in SEC filings, no litigation, labor or other compliance issues, environmental, intellectual property and title matters and compliance with various laws such as the Foreign Corrupt Practices Act; and

•

covenants regarding matters such as registration of warrant shares, no integration with other offerings, no stockholder rights plans, no material nonpublic information, use of proceeds, indemnification of purchasers, reservation and listing of shares of common stock, and no subsequent equity sales for seventy-five days.

We expect to deliver the shares of common stock, the Pre-Funded Warrants and the Common Warrants being offered pursuant to this prospectus on or about , 2025. There is no minimum number of securities or amount of proceeds that is a condition to closing of this offering.

Fees and Expenses

We have agreed to pay the Placement Agent a total cash fee equal to 7.5% of the aggregate gross proceeds raised in the offering and a management fee equal to 1.0% of the gross proceeds raised in the offering. We will reimburse the Placement Agent a nonaccountable expense allowance of $30,000, its legal fees and expenses in an amount up to $100,000 and its clearing expense in an amount up to $15,950 in connection with this offering. We estimate the total offering expenses of this offering that will be payable by us, excluding the Placement Agent fees and expenses, will be approximately $0.1 million.

Placement Agent Warrants

In addition, we have agreed to issue to the Placement Agent or its designees the Placement Agent Warrants, to purchase up to 7.5% of the aggregate number of shares of common stock sold in this offering (including shares underlying any Pre-Funded Warrants), at an exercise price equal to 125% of the public offering price per share and accompanying Common Warrants to be sold in this offering.

The Placement Agent Warrants

TABLE OF CONTENTS

will expire five years from the commencement of sales under this offering. If at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of warrant shares by the holders of the Placement Agent warrants, then the Placement Agent warrants may be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the holders shall be entitled to receive a number of warrant shares as calculated in the Placement Agent warrants.

The Placement Agent Warrants provide for customary anti-dilution provisions (for share dividends, splits and recapitalizations and the like) consistent with FINRA Rule 5110. Pursuant to FINRA Rule 5110(e), the Placement Agent Warrants and any shares issuable thereunder shall not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following the date of commencement of sales of this offering, except the transfer of any security: (i) by operation of law or by reason of reorganization of the issuer; (ii) to any FINRA member firm participating in the offering and the officers, partners, registered persons or affiliates thereof, if all securities so transferred remain subject to the lock-up restriction set forth above for the remainder of the time period; (iii) if the aggregate amount of our securities held by the Placement Agent persons does not exceed 1% of the securities being offered; (iv) that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member manages or otherwise directs investments by the fund and the participating members in the aggregate do not own more than 10% of the equity in the fund; (v) the exercise or conversion of any security, if all securities remain subject to the lock-up restriction set forth above for the remainder of the time period; (vi) so long as we continue to meet the registration requirements of Forms S-3; or (vii) back to us in a transaction exempt from registration under the Securities Act.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Bio-Path Holdings, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Bio-Path Holdings, Inc. (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, shareholders’ equity and cash flows for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

The Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company has suffered recurring losses from operations and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosure to which it relates.

TABLE OF CONTENTS

				Prepaid or Accrued Research and Development Expenses
	Description of the Matter			During 2023, the Company incurred $11.6 million for research and development expenses and as of December 31, 2023 recorded prepaid clinical trial expenses of $0.9 million and accrued clinical trial expense of $0.8 million. As disclosed in Note 2 to the consolidated financial statements, research and development costs are charged to expense when the related goods are delivered, or services are performed. The Company estimated its clinical trial expense based on a cost per patient calculation, which is derived from estimated start-up costs, clinical trial costs based on the number of patients and length of treatment and clinical study report costs. The Company recorded an accrual or prepaid for clinical trial expenses based on its estimated clinical trial expense as compared to payments made to the Company’s third-party clinical research organization, laboratories and clinical investigation sites. Auditing the Company’s accrued and prepaid research and development expenses is complex due to significant judgment and estimates made by management in determining the clinical trial expenses incurred, which include inputs such as number of patients, length of treatment and clinical study report costs, compared to payments the Company has made.
	How We Addressed the Matter in Our Audit			To test the prepaid research and development expenses for significant clinical trials, our audit procedures included, among others, testing the accuracy and completeness of the underlying data used in the estimates and evaluating the significant assumptions that are used by management to estimate the recorded prepayments. To test the significant assumptions, we corroborated the patient enrollment, length of treatment, trial timeline and progress of research and development activities through discussion with the Company’s research and development personnel that oversee the research and development projects, inspected the Company’s contracts with third parties and any pending change orders to assess the impact on amounts recorded, and obtained information directly from vendors of their costs incurred to date. We tested a sample of transactions and compared the costs against related invoices and contracts. We also performed analytics over fluctuations in accruals or prepaid balances by trial throughout the year and tested subsequent payments to evaluate the completeness of the research and development expenses recognized.

We have served as the Company’s auditor since 2020.

Bio-Path Holdings, Inc.

Notes to Consolidated Financial Statements
December 31, 2023

Unless the context requires otherwise, references in these Notes to the Consolidated Financial Statements to “we,” “our,” “us,” “the Company” and “Bio-Path” refer to Bio-Path Holdings, Inc. and its subsidiary. Bio-Path Holdings, Inc.’s wholly-owned subsidiary, Bio-Path, Inc., is sometimes referred to herein as “Bio-Path Subsidiary.”

Organization and Business

The Company is a clinical and preclinical stage oncology focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target specific protein inhibition for any gene product that is over-expressed in disease. The Company’s drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a lipid bilayer having neutral charge. The Company believes this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. Through testing in numerous animal studies and dosing in clinical trials, the Company’s DNAbilize® drug candidates have demonstrated an excellent safety profile. DNAbilize® is a registered trademark of the Company. Using DNAbilize® as a platform for drug development and manufacturing, the Company currently has four antisense drug candidates in development to treat at least five different cancer disease indications.

The Company was incorporated in May 2000 as a Utah corporation. In February 2008, Bio-Path Subsidiary completed a reverse merger with the Company, which at the time was traded over the counter and had no current operations. The prior name of the Company was changed to Bio-Path Holdings, Inc. and the directors and officers of Bio-Path Subsidiary became the directors and officers of Bio-Path Holdings, Inc. Effective December 31, 2014, the Company changed its state of incorporation from Utah to Delaware through a statutory conversion pursuant to the Utah Revised Business Corporation Act and the Delaware General Corporation Law.

On February 22, 2024, the Company effected a reverse stock split of its outstanding shares of common stock at a ratio of 1-for-20, and its common stock began trading on the spilt-adjusted basis on the Nasdaq Capital Market at the commencement of trading on February 23, 2024. All common stock share and per share amounts in this Annual Report on Form 10-K have been adjusted to give effect to the 1-for-20 reverse stock split.

The Company’s operations to date have been limited to organizing and staffing the Company, acquiring, developing and securing its technology and undertaking product development for a limited number of product candidates. As the Company has not begun its planned principal operations of commercializing a product candidate, the Company’s activities are subject to significant risks and uncertainties, including the potential requirement to secure additional funding, the outcome of the Company’s clinical trials and failing to operationalize the Company’s current drug candidates before another company develops similar products.

Summary of Significant Accounting Policies

Principles of Consolidation — The consolidated financial statements include the accounts of Bio-Path Holdings, Inc. and its wholly owned subsidiary Bio-Path, Inc. All intercompany accounts and transactions have been eliminated in consolidation.

Cash and Cash Equivalents — The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Concentration of Credit Risk — Financial instruments that potentially subject the Company to a significant concentration of credit risk consist of cash. The Company maintains its cash balances with one

major commercial bank, JPMorgan Chase Bank. The balances are insured by the Federal Deposit Insurance Corporation (the “FDIC”) up to $250,000. As a result, as of December 31, 2023, approximately $0.8 million of its cash balance was not covered by the FDIC. As of December 31, 2022, the Company had approximately $10.4 million in cash on-hand, of which approximately $10.1 million was not covered by the FDIC. To date, the Company has not incurred any losses on its cash balances.

Furniture, fixtures and equipment — Furniture, fixtures and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets. Depreciation expense was $0.1 million for each of the years ended December 31, 2023 and 2022, respectively.

The estimated useful lives are as follows:

Computers and equipment — 3 years
Furniture and fixtures — 7 years
Scientific equipment — 7 years
Leasehold improvements — Lesser of useful life or lease term

Major additions and improvements are capitalized, while costs for minor replacements, maintenance and repairs that do not increase the useful life of an asset are expensed as incurred.

Long-Lived Assets — The Company’s long-lived assets consist of furniture, fixtures and equipment, leasehold improvements and right-of-use operating assets. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by a comparison of the asset’s carrying amount to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Research and Development Costs — Costs and expenses that can be clearly identified as research and development are charged to expense. Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. If the goods will not be delivered, or services will not be rendered, then the capitalized advance payment is charged to expense.

The Company estimates its clinical trial expense each period based on a cost per patient calculation which is derived from estimated start-up costs, clinical trial costs based on the number of patients and length of treatment and clinical study report costs. These services are performed by the Company’s third-party clinical research organizations, laboratories and clinical investigative sites. The expense is recorded in research and development expense each period. Amounts that have been prepaid in advance of work performed are recorded in other current assets.

Stock-Based Compensation — The Company records stock-based compensation expense measured using the fair value method. The Company uses the Black-Scholes option valuation model to calculate stock-based compensation at the date of grant. Option pricing models require the input of highly subjective assumptions, including the expected price volatility. The Company’s policy is to estimate forfeitures at the grant date and revise, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Changes in these assumptions can materially affect the fair value estimate.

Warrants — The Company determines whether warrants should be classified as a liability or equity. For warrants classified as liabilities, the Company estimates the fair value of the warrants at each reporting period using Level 3 inputs with changes in fair value recorded in the Consolidated Statement of Operations as change in fair value of warrant liability. The estimates in valuation models are based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk-free interest rate and the fair value of the common stock underlying the warrants, and could differ materially in the future. The Company will continue to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value from the prior period until the earlier of the exercise or expiration of the applicable warrant.

TABLE OF CONTENTS

Net Loss Per Share — Basic net loss per common share is computed by dividing net loss attributable to common stockholders for the period by the weighted average number of common shares outstanding during the period. Although there were warrants and stock options outstanding during 2023 and 2022, they were not included in the computation of any diluted per-share amount when a loss exists, as it would be anti-dilutive. Consequently, diluted net loss per share as presented in the financial statements is equal to basic net loss per share for the years 2023 and 2022. The calculation of diluted earnings per share for 2023 did not include 43,383 shares and 190,063 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of December 31, 2023, as the effect would be anti-dilutive. The calculation of diluted earnings per share for 2022 did not include 32,871 shares and 60,027 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of December 31, 2022, as the effect would be anti-dilutive.

Use of Estimates — The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States (“U.S.”) requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates and judgments, which are based on historical and anticipated results and trends as well as on various other assumptions that the Company believes to be reasonable under the circumstances. By their nature, estimates are subject to an inherent degree of uncertainty and, as such, actual results may differ from the Company’s estimates. These estimates include prepaid and accrued clinical trial costs, stock-based compensation expense, valuation of warrants and valuation of deferred tax assets.

Income Taxes — Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

Liquidity — Since its inception, the Company has devoted substantially all of its efforts to product development, raising capital and building infrastructure, and has not generated significant revenues from its planned principal operations. The Company does not anticipate generating significant revenues for the foreseeable future. The Company’s activities are subject to significant risks and uncertainties.

The Company has experienced significant losses since its inception, including net losses of $16.1 million and $13.9 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, the Company had an accumulated deficit of $107.6 million and $1.1 million in cash and cash equivalents. The Company has no debt commitments. Substantially all of the Company’s net losses have resulted from costs incurred in connection with its research and development activities and its general and administrative expenses to support operations. The Company’s net losses may fluctuate significantly from quarter to quarter and year to year.

The Company’s available cash at December 31, 2023 will not be sufficient to fund current liabilities and capital expenditure requirements. Therefore, substantial doubt exists about the Company’s ability to continue as a going concern. The Company expects to continue to incur significant operating expenses for the foreseeable future in connection with its ongoing activities, including conducting clinical trials, manufacturing development and seeking regulatory approval of its drug candidates, prexigebersen, BP1002, BP1003 and BP1001-A. Accordingly, the Company will continue to require substantial additional capital to fund its projected operating requirements. Such additional capital may not be available when needed or on terms favorable to the Company. In addition, the Company may seek additional capital due to favorable market conditions or strategic considerations, even if it believes it has sufficient funds for its current and future operating plan. There can be no assurance that the Company will be able to continue to raise additional capital through the sale of securities in the future. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers and/or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations, financial condition and future prospects.

Recent Accounting Pronouncements — From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) that are adopted by the Company as of the specified effective date. There are no recent accounting pronouncements that have a material impact on the Company’s consolidated financial statements.

Prepaid Drug Product

Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future clinical development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. The Company recognized certain expenses and incurred installment costs for its contract drug manufacturing and raw material suppliers with prepayments totaling $3.6 million as of December 31, 2022 pursuant to drug supply contracts for the manufacture and delivery of prexigebersen for testing in a Phase 2 clinical trial, BP1001-A for testing in a Phase 1 clinical trial and BP1002 for testing in a Phase 1 clinical trial.

TABLE OF CONTENTS

Warrant Liability

In connection with the 2023 Public Offering (as defined in Note 10), the Company issued the 2023 Warrants (as defined in Note 10). The 2023 Warrants contain a provision applicable in the event of a fundamental transaction whereby the volatility used to calculate the warrant exercise terms is fixed and meets the definition of a derivative.

Due to this provision and in accordance with ASC 815 Derivatives and Hedging, the 2023 Warrants were classified as a liability and recorded at fair value using the Black-Scholes valuation model. The estimated fair value of the warrant liability for the 2023 Warrants on the closing date of the 2023 Public Offering, August 7, 2023, was $1.2 million. As of December 31, 2023, the fair value of the warrant liability was $0.9 million. The net change in fair value during the year of $0.3 million, comprised of a decrease in fair value of $0.6 million related to warrant exercises partially offset by an increase in fair value of the warrant liability for the 2023 Warrants of $0.3 million, is shown as other loss on the Company’s Consolidated Statements of Operations. The Company will continue to measure the fair value of the 2023 Warrants each quarter until they are exercised or expire, and any change will be adjusted accordingly on the Company’s financial statements.

Fair Value Measurements

In accordance with ASC 820, the Company uses various inputs to measure the 2023 Warrants on a recurring basis to determine the fair value of the liability. ASC 820 also establishes a hierarchy categorizing inputs into three levels used to measure and disclose fair value. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to unobservable inputs. An explanation of each level in the hierarchy is described below:

Level 1 — Unadjusted quoted prices in active markets for identical instruments that are accessible by the Company on the measurement date

Level 2 — Quoted prices in markets that are not active or inputs which are either directly or indirectly observable

Level 3 — Unobservable inputs for the instrument requiring the development of assumptions by the Company

The following table summarizes the Company’s 2023 Warrants measured at fair value within the hierarchy on a recurring basis as of December 31, 2023:

Stockholders’ Equity

Issuances of Common Stock — On November 6, 2022, the Company entered into a placement agency agreement with Roth Capital Partners, LLC relating to the 2022 Registered Direct Offering and the 2022 Private Placement. In addition, on November 6, 2022, the Company entered into securities purchase agreements with several institutional and accredited investors pursuant to which the Company agreed to sell, in a registered direct offering, an aggregate of 40,000 shares of our common stock for gross proceeds of approximately $2.0 million under the base prospectus contained in the Company’s shelf registration statement on Form S-3 filed with the SEC, which was declared effective by the SEC on June 14, 2022 (File No. 333-265282) (the “2022 Shelf Registration Statement”), and a related prospectus supplement filed with the SEC on November 9, 2022 (the “2022 Registered Direct Offering”). In a concurrent private placement, the Company also agreed pursuant to the securities purchase agreements to issue to such investors warrants to purchase up to 40,000 shares of its common stock (the “2022 Private Placement”). The 2022 Registered Direct Offering and the 2022 Private Placement closed on November 9, 2022. The net proceeds from the offerings, after deducting the placement agent’s fees and expenses and the Company’s offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.7 million.

On August 3, 2023, the Company entered into a placement agency agreement with Roth Capital Partners, LLC relating to a best efforts public offering of an aggregate of 175,000 shares of our common stock, together with warrants to purchase up to 175,000 shares of the Company’s common stock (“the 2023 Warrants”), for gross proceeds of approximately $2.1 million (the “2023 Public Offering”). The 2023 Public Offering was made pursuant to a registration statement on Form S-1, as amended (File No. 333-272879), which was declared effective by the SEC on August 2, 2023. The 2023 Public Offering closed on August 7, 2023. The net proceeds from the offering, after deducting the placement agent’s fees and expenses and the Company’s offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offering, were approximately $1.7 million.

During the year ended December 31, 2023, the Company issued an aggregate of 44,625 shares of its common stock pursuant to the exercise of warrants at a weighted average exercise price of approximately $12.00 per share. The net proceeds to the Company from the exercise of the warrants were approximately $0.5 million. The Company did not issue any common stock pursuant to the exercise of warrants during the year ended December 31, 2022.

Stockholders’ Equity totaled $0.4 million as of December 31, 2023 compared to $14.2 million as of December 31, 2022. There were 617,633 shares of common stock issued and outstanding as of December 31, 2023. There were no shares of preferred stock issued and outstanding as of December 31, 2023.

Stock-Based Compensation Plan

TABLE OF CONTENTS

the Company’s employees, non-employee directors and consultants. As of December 31, 2023, there were 65,000 shares of common stock reserved for future issuance of awards under the 2022 Plan. Under the 2022 Plan, the exercise price of awards is determined by the Board of Directors or the compensation committee of the Board of Directors, and for options, may not be less than the fair market value as determined by the closing stock price at the date of the grant. Each option and award under the 2022 Plan shall vest and expire as determined by the Board of Directors or the compensation committee. Options expire no later than ten years from the date of grant. All grants provide for accelerated vesting if there is a change in control, as defined in the 2022 Plan.

Stock option awards granted for the years 2023 and 2022 were estimated to have a weighted average fair value per share of $27.80 and $74.20, respectively. The fair value calculation is based on stock options granted during the year using the Black-Scholes option-pricing model on the date of grant. In addition, for all stock options granted, exercise price was determined based on the fair value as determined by the closing stock price at the date of the grant. For stock options granted during 2023 and 2022 the following weighted average assumptions were used in determining fair value:

	2023		2022
Risk-free interest rate		3.42%		2.43%
Expected volatility		129%		127%
Expected term in years		6.0		6.0
Dividend yield		—%		—%

The Company determines the expected term of its stock option awards using the simplified method based on the weighted average of the length of the vesting period and the term of the exercise period. Expected volatility is determined by the volatility of the Company’s historical stock price over the expected term of the grant. The risk-free interest rate for the expected term of each option granted is based on the U.S. Treasury yield curve in effect at the time of grant.

Option activity under the Plans for the year ended December 31, 2023 was as follows:

	Options		Weighted- Average Exercise Price			Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value
	(in thousands)
Outstanding at December 31, 2022		33		$	233.40		7.9		$	—

Exercisable at December 31, 2023		25		$	236.20		6.9		$	—

The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s closing stock price on December 31, 2023 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2023. This amount changes based on the fair value of the Company’s stock.

Leases

In April 2014, the Company entered into a five-year lease agreement for administrative office space located in Bellaire, Texas. The term of the lease began on August 1, 2014 and was set to expire on July 31, 2019; however, in May 2019, the Company entered into an amendment to the lease agreement to extend the term of the lease for a period of five years, beginning on August 1, 2019 and ending on October 31, 2024.

In April 2016, the Company entered into a three-year lease agreement for lab space located in Bellaire, Texas. The term of lease began on May 1, 2016 and was set to expire on April 30, 2019; however, in December 2018, the Company entered into an amendment to the lease agreement to extend the term for a period of three years, beginning on May 1, 2019 and ending on April 30, 2022. In January 2022, the Company exercised an option in the lease agreement amendment to extend the term of the lease to April 30, 2025.

At the inception of an agreement, the Company determines if the agreement is a lease based on the unique facts and circumstances in each agreement. Lease classification, recognition, and measurement are then determined at the lease commencement date. For agreements that contain a lease, the Company identifies lease and non-lease components, determines the consideration in the contract, determines whether the lease is an operating or financing lease and recognizes right of use (“ROU”) assets and lease liabilities. Lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable so the Company uses an incremental borrowing rate based on the information available at the lease commencement date, which represents an estimated rate that would be incurred to borrow over a similar term in a similar economic environment. The weighted average incremental borrowing rate utilized on its lease liabilities as of December 31, 2023 was 8.0%.

The Company’s current leases include options to renew which can impact the lease term. The exercise of these options is at its discretion and the Company does not include any of these options within the expected lease term as there is no reasonable certainty these options will be exercised. Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis within its consolidated financial statements. The Company’s leases are included in ROU assets, current portion of lease liabilities and noncurrent lease liabilities in its consolidated balance sheet for the year ended December 31, 2023.

Benefit Plan

The Company initiated a contribution savings plan under Section 401(k) of the Internal Revenue Code in 2016. Under the plan, all eligible employees may contribute up to the statutory allowable amount governed by the Internal Revenue Service for any calendar year. The Company makes matching contributions equal to 100% of the first 3% and 50% of the next 2% of each employee’s base salary up to the allowable amount, which is fully vested on the date the matching contributions are made. For the years ended December 31, 2023 and 2022, matching contributions totaled $52,000 and $37,000, respectively.

Income Taxes

At December 31, 2023, the Company had a net operating loss carryforward for federal income tax purposes of $97.3 million, $35.8 million of which begins to expire in varying amounts in tax years 2026 through 2037. Approximately $61.5 million of net operating losses, incurred after December 31, 2017, carryforward indefinitely. Additionally, the Company has a research and development tax credit carryforward of $6.5 million for federal income tax purposes that begins to expire in varying amounts in tax year 2028. In connection with the Company’s equity transactions in 2007 and 2019, the Company determined that the utilization of net operating losses in future years may be subject to limitations by reason of an “ownership change” as defined under Section 382 of the Internal Revenue Code (IRC) (“Section 382 Limitation”). As a result of the Section 382 Limitation, the Company may not be able to fully utilize its net operating loss carry forwards and other tax credit carry forwards to offset future taxable income. Based on the Company’s estimated impact of the ownership change and Section 382 Limitation as of December 31, 2023, the net operating loss was reduced to $88.3 million, and the tax credits were reduced to $4.8 million for credits earned after the 2019 ownership change. During the year ended December 31, 2023, the Company raised additional equity capital and has yet to determine whether an ownership change occurred. If an ownership change is determined to have occurred in 2023, additional limitations on the Company’s net operating losses incurred prior to the ownership change may apply. Based on operations through December 31, 2023, the Company has estimated that the net operating loss and tax credits should be further reduced by providing a full valuation allowance against both.

In assessing the ability to realize its deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers evidence such as the reversal of deferred tax liabilities, projected future results of operations, and tax planning strategies in making this assessment. Based upon the level of historical taxable income, significant book losses during the current and prior periods, and projections for future results of operations over the periods in which the deferred tax assets are deductible, among other factors, management continues to conclude that the Company does not meet the “more likely than not” requirement of ASC 740 in order to recognize deferred tax assets. As such, a valuation allowance has been recorded to offset the Company’s net deferred tax assets at December 31, 2023. The Company recorded an increase in the valuation allowance of $5.0 million for the year ended December 31, 2023.

TABLE OF CONTENTS

Due to the uncertainty surrounding the realization of the benefits of its deferred assets, including NOL carryforwards, the Company has provided a 100% valuation allowance on its net deferred tax assets at December 31, 2023 and 2022. The valuation allowance was $24.2 million and $19.1 million as of December 31, 2023 and 2022, respectively.

As of December 31, 2023, the Company had no unrecognized income tax benefits. The Company’s policy for classifying interest and penalties associated with unrecognized income tax benefits is to include such items as tax expense. No interest or penalties have been recorded as of the year ended December 31, 2023, and no interest or penalties have been accrued as of December 31, 2023 and 2022, respectively.

The Company’s open years for Internal Revenue Service (IRS) examination purposes due to normal statute of limitation are 2020, 2021 and 2022. However, since the Company has operating loss carryforwards, the IRS has the ability to make adjustments to items that originate in a year otherwise barred by the

F-18

TABLE OF CONTENTS

statute of limitations under Section 6501 of the IRC of 1986, as amended, in order to redetermine tax for an open year to which those items are carried. Therefore, in a year in which a net operating loss deduction was claimed, the IRS may examine the year in which the net operating loss was generated and adjust it accordingly for purposes of assessing additional tax in the year the net operating loss was claimed. The Company is not currently under examination by the IRS or any other taxing authorities.

Notes to the Unaudited Condensed Consolidated Financial Statements

Unless the context requires otherwise, references in these Notes to the Condensed Consolidated Financial Statements to “we,” “our,” “us,” “the Company” and “Bio-Path” refer to Bio-Path Holdings, Inc. and its subsidiary. Bio-Path Holdings, Inc.’s wholly-owned subsidiary, Bio-Path, Inc., is sometimes referred to herein as “Bio-Path Subsidiary.”

The accompanying unaudited condensed interim financial statements have been prepared in conformity with the authoritative U.S. generally accepted accounting principles (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, do not include all information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of the results of operations and financial position have been included and all such adjustments are of a normal recurring nature. The unaudited quarterly financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K of the Company as of and for the fiscal year ended December 31, 2023. The results of operations for the period ended September 30, 2024 are not necessarily indicative of the results for a full-year period.

Organization and Business

The Company is a clinical and preclinical stage oncology-focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target-specific protein inhibition for any gene product that is over-expressed in disease. The Company’s drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a lipid bilayer having neutral charge. The Company believes this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. Through testing in numerous animal studies and dosing in clinical trials, the Company’s DNAbilize® drug candidates have demonstrated an excellent safety profile. DNAbilize® is a registered trademark of the Company. Using DNAbilize® as a platform for drug development and manufacturing, the Company currently has four antisense drug candidates in development to treat at least five different cancer disease indications.

The Company was incorporated in May 2000 as a Utah corporation. In February 2008, Bio-Path Subsidiary completed a reverse merger with the Company, which at the time was traded over the counter and had no current operations. The prior name of the Company was changed to Bio-Path Holdings, Inc. and the directors and officers of Bio-Path Subsidiary became the directors and officers of Bio-Path Holdings, Inc. Effective December 31, 2014, the Company changed its state of incorporation from Utah to Delaware through a statutory conversion pursuant to the Utah Revised Business Corporation Act and the Delaware General Corporation Law.

Significant Accounting Policies

Net Loss Per Share — Basic net loss per common share is computed by dividing the net loss for the period by the weighted average number of shares of common stock outstanding during the period. Although

F-24

TABLE OF CONTENTS

there were warrants and stock options outstanding as of September 30, 2024 and 2023, no potential common shares are included in the computation of any diluted per share amount, as they would be antidilutive. Consequently, diluted net loss per share as presented in the condensed consolidated financial statements is equal to basic net loss per share for the three and nine months ended September 30, 2024 and 2023. The calculation of diluted earnings per share for 2024 did not include 96,389 shares and 4,421,679 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of September 30, 2024 as the effect would be antidilutive. The calculation of diluted earnings per share for 2023 did not include 43,383 shares and 234,688 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of September 30, 2023 as the effect would be antidilutive.

Liquidity — The Company’s available cash and cash equivalents of $0.6 million at September 30, 2024 along with the net proceeds received from the October 2024 Private Placement (see Note 12) will not be sufficient to fund liquidity and capital expenditure requirements for the next 12 months from the date of issuance of these consolidated financial statements. Therefore, substantial doubt exists about the Company’s ability to continue as a going concern. The Company expects to continue to incur significant operating expenses for the foreseeable future in connection with its ongoing activities, including conducting clinical trials, manufacturing development and seeking regulatory approval of its drug candidates, prexigebersen, BP1002, BP1003 and BP-1001A. Accordingly, the Company will continue to require substantial additional capital to fund its projected operating requirements. Such additional capital may not be available when needed or on terms favorable to the Company. In addition, the Company may seek additional capital due to favorable market conditions or strategic considerations, even if it believes it has sufficient funds for its current and future operating plan. There can be no assurance that the Company will be able to continue to raise additional capital through the sale of securities in the future. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers and/or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations, financial condition and future prospects.

Warrants — The Company determines whether warrants should be classified as a liability or equity. For warrants classified as liabilities, the Company estimates the fair value of the warrants at each reporting period using Level 3 inputs with changes in fair value recorded in the Condensed Consolidated Statement of Operations as change in fair value of warrant liability. The estimates in valuation models are based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk-free interest rate and the fair value of the common stock underlying the warrants, and could differ materially in the future. The Company will continue to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value from the prior period until the earlier of the exercise or expiration of the applicable warrant.

Fair Value — The fair values of cash and cash equivalents, accounts payable and accrued liabilities approximate their carrying values because of the short-term maturities of these instruments.

Prepaid Drug Product

Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future clinical development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. The Company recognized certain expenses and incurred installment costs for its contract drug manufacturing and raw material suppliers with prepayments totaling $0.6 million as of December 31, 2023 pursuant to drug supply contracts for the manufacture and delivery of prexigebersen for testing in a Phase 2 clinical trial. The Company recognized certain expenses and incurred additional installment costs during the first nine months of 2024, with advanced payments remaining to be expensed totaling $0.5 million as of September 30, 2024.

Other Current Assets

As of September 30, 2024, other current assets included prepaid expenses of $1.8 million, comprised primarily of prepayments of $1.4 million made for the Company’s clinical trials for BP1001-A in solid tumors and BP1002 in separate clinical trials for AML and lymphoma. Additionally, the Company had prepaid insurance expenses of $0.4 million. As of December 31, 2023, other current assets included prepaid

F-25

TABLE OF CONTENTS

expenses of $1.4 million, comprised primarily of prepayments of $0.9 million made for the Company’s clinical trials for BP1002 in AML and lymphoma and BP1001-A in solid tumors as well as prepaid insurance of $0.3 million, prepaid Delaware franchise tax of $0.1 million and other prepaid expenses of $0.1 million.

Accounts Payable

As of September 30, 2024, current liabilities included accounts payable of $1.0 million, comprised primarily of expenses related to clinical trial expenses of $0.5 million, legal and patent fees of $0.2 million, expenses related to the Company’s recent financing activity of $0.2 million and other accounts payables of $0.1 million. As of December 31, 2023, current liabilities included accounts payable of $0.5 million, comprised primarily of expenses related to clinical trial expenses of $0.3 million, legal and patent fees of $0.1 million and other accounts payables of $0.1 million.

Accrued Expense

As of September 30, 2024, current liabilities included accrued expenses of $2.3 million, comprised primarily of accrued clinical trial expenses of $1.6 million, employee vacation and bonus expenses of $0.3 million, professional and consulting fees of $0.1 million, drug manufacturing development and testing services of $0.1 million, legal and patent fees of $0.1 million and other accrued expenses of $0.1 million. As of December 31, 2023, current liabilities included accrued expenses of $1.3 million, comprised primarily of expenses related to the Company’s clinical trial for prexigebersen in AML of $0.8 million, accrued employee vacation and bonus expenses of $0.2 million, professional and consulting fees of $0.1 million, legal and patent fees of $0.1 million and other accrued expenses of $0.1 million.

Warrant Liability

In connection with the 2023 Public Offering, the 2024 March Registered Direct Offering and the 2024 April Registered Direct Offering (each as defined below), the Company issued the 2023 Warrants, the March 2024 Private Placement warrants and the April 2024 Private Placement warrants (each as defined below, collectively, the “Warrants”). The Warrants contain a provision applicable in the event of a fundamental transaction whereby the volatility used to calculate the warrant exercise terms is fixed and meets the definition of a derivative.

Due to this provision and in accordance with ASC 815 Derivatives and Hedging, the Warrants were classified as a liability and recorded at fair value using the Black-Scholes valuation model. The estimated fair value of the warrant liability for the 2023 Warrants as of December 31, 2023, was $0.9 million. The estimated fair value of the warrant liability for the March 2024 Private Placement warrants on the closing date of the March 2024 Registered Direct Offering, March 27, 2024, was $0.3 million. The estimated fair value of the warrant liability for the April 2024 Private Placement warrants on the closing date of the April 2024 Registered Direct Offering, April 19, 2024, was $1.4 million. As of September 30, 2024, the fair value of the total warrant liability was $0.3 million. The net change in fair value for the three and nine months ended, September 30, 2024 was $0.5 million and $2.2 million, respectively, and are shown as other income on the Company’s Condensed Consolidated Statements of Operations. The Company will continue to measure the fair value of the Warrants each quarter until they are exercised or expire, and any change will be adjusted accordingly on the Company’s financial statements.

Fair Value Measurements

In accordance with ASC 820, the Company uses various inputs to measure the Warrants on a recurring basis to determine the fair value of the liability. ASC 820 also establishes a hierarchy categorizing inputs into three levels used to measure and disclose fair value. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to unobservable inputs. An explanation of each level in the hierarchy is described below:

Level 1 — Unadjusted quoted prices in active markets for identical instruments that are accessible by the Company on the measurement date

Level 2 — Quoted prices in markets that are not active or inputs which are either directly or indirectly observable

F-26

As of stockholder approval of the 2022 Plan on December 15, 2022, no further awards will be made under the 2017 Plan. The 2022 Plan provides for the grant of Incentive Stock Options, Non-Qualified Stock Options, Restricted Shares, Restricted Share Units, Stock Appreciation Rights and other stock-based awards, or any combination of the foregoing, to the Company’s employees, non-employee directors and consultants. As of December 31, 2023, there were 65,000 shares of common stock reserved for future issuance of awards under the 2022 Plan. Under the 2022 Plan, the exercise price of awards is determined by the Board of Directors or the compensation committee of the Board of Directors, and for options, may not be less than the fair market value as determined by the closing stock price at the date of the grant. Each option and award under the 2022 Plan shall vest and expire as determined by the Board of Directors or the compensation committee. Options expire no later than ten years from the date of grant. All grants provide for accelerated vesting if there is a change in control, as defined in the 2022 Plan.

Stock-based compensation expense for the three months ended September 30, 2024 and 2023 was $0.1 million and $0.2 million, respectively. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for each of the three months ended September 30, 2024 and 2023 was $0.1 million and $0.2 million, respectively. Stock-based compensation expense for personnel involved in the Company’s research and development activities for the three months ended September 30, 2024 and 2023 was $34,000 and $45,000, respectively.

Stock-based compensation expense for the nine months ended September 30, 2024 and 2023 was $0.4 million and $0.6 million, respectively. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for the nine months ended September 30, 2024 and 2023 was $0.3 million and $0.4 million, respectively. Stock-based compensation expense for personnel involved in the Company’s research and development activities for each of the nine months ended September 30, 2024 and 2023 was $0.1 million.

The Company utilized the Black-Scholes valuation model for estimating the fair value of the stock options granted, with the following weighted-average assumptions for options granted in the nine months ended September 30, 2024 and 2023:

	2024		2023
Risk-free interest rate		4.00%		3.42%
Expected volatility		134%		129%

The following summary represents option activity under the Company’s stock-based compensation plans for the nine months ended September 30, 2024:

	Options		Weighted- Average Exercise Price
	(in thousands)
Outstanding at December 31, 2023		43		$	161.20
Granted		53		$	1.55
Outstanding at September 30, 2024		96		$	71.40
Vested and expected to vest September 30, 2024		94		$	72.74
Exercisable at September 30, 2024		34		$	184.17

As of September 30, 2024, outstanding stock options did not have any aggregate intrinsic value. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s closing stock price on September 30, 2024 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2024. This amount changes based on the fair value of the Company’s stock.

As of September 30, 2024, unamortized stock-based compensation expense for all outstanding options was $0.5 million, which is expected to be recognized over a weighted average vesting period of 1.6 years.

Item 14. Indemnification of Directors and Officers.

Section 102(b)(7) of the Delaware General Corporation Law (the “DGCL”) permits a corporation to eliminate or limit the personal liability of its directors to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our certificate of incorporation provides that to the fullest extent elimination or limitation of personal liability of directors is permitted by the DGCL, no director of the Company shall be liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director.

Section 145 of the DGCL permits a corporation to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he or she is party or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnification for such expenses which the Court of Chancery or such other court shall deem proper.

Our first amended and restated bylaws, as amended, and our certificate of incorporation provide that each person (and the heirs, executors or administrators of such person) who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director or officer of the Company shall be indemnified and held harmless by the Company to the fullest extent permitted by applicable law. Our certificate of incorporation also states that we will pay or reimburse the reasonable expenses incurred in defending any such action, suit or proceeding in advance of its final disposition if we have received an undertaking by the person receiving such payment or reimbursement to repay all amounts advanced if it should be ultimately determined that he or she is not entitled to be indemnified.

II-1

TABLE OF CONTENTS

We have entered into indemnification agreements with each of our directors. The contractual rights to indemnification provided by these indemnity agreements are subject to the limitations and conditions specified in such agreements.

The effect of the foregoing is to require us to indemnify our officers and directors for any claim arising against such persons in their official capacities if such person acted in good faith and in a manner that he or she reasonably believed to be in or not contrary to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”) may be permitted to our directors and officers, we have been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

We have directors and officers insurance which includes insurance for claims against these persons brought under securities laws.

The Company agreed to pay Wainwright (i) a cash fee equal to 7.5% of the aggregate gross proceeds of the October 2024 Private Placement, (ii) a management fee of 1.0% of the aggregate gross proceeds of the October 2024 Private Placement, (iii) upon any exercise for cash of the series a warrants or series b warrants, a cash fee of 7.5% of the aggregate gross exercise price paid in cash, and (iv) upon any exercise for cash of the series a warrants or series b warrants, a management fee of 1.0% of the aggregate gross exercise price paid in cash. In addition, the Company agreed to pay Wainwright certain expenses and issued to Wainwright or its designees warrants to purchase up to an aggregate of 344,828 shares of Common Stock at an exercise price equal to $1.0875 per share. Upon any exercise for cash of the series a warrants or series b warrants, the Company shall also issue warrants to Wainwright to purchase the number of shares of Common Stock equal to 7.5% of the aggregate number of such shares of Common Stock underlying the series a warrants or series b warrants that have been so exercised at an exercise price equal to $1.0875 per share, which warrants will be in substantially the same form and on the same terms as the placement agent warrants. The placement agent warrants are exercisable starting on the date of stockholder approval was obtained and have a term of exercise equal to five years from the date stockholder approval was obtained. The shares of Common Stock and the warrants issued in connection with the October 2024 Private Placement were issued in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act and/or Regulation D promulgated thereunder. Each investor represented that it was an accredited investor, as defined in Rule 501 of Regulation D promulgated under the Securities Act. The net proceeds from the offering, after deducting the placement agent’s fees and expenses and our offering expenses, and excluding the proceeds, if any, from the exercises of the warrants issued in the offering, were approximately $3.5 million.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i), (ii), and (iii) do not apply if the information required

TABLE OF CONTENTS

to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement;

(2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4) that, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date;

(5) that, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser;

(6) that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

II-10

TABLE OF CONTENTS

(7) insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue; and

(8) that:

(i) for purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective; and

(ii) for the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Section 2.         Exercise.

a)       Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”). If the Holder exercises any portion of this Warrant by cashless exercise pursuant to Section 2(c), then the Notice of Exercise shall include the VWAP and Bid Price (each as defined below) used by the Holder in calculating the Warrant Shares to be issued pursuant to Section 2(c) so that the Company may independently confirm the Holder’s calculations. Within the earlier of (i) one (1) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the Warrant Shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation as soon as reasonably practicable following the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Trading Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b)       Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $[ ], subject to adjustment hereunder (the “Exercise Price”).

c)       Cashless Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) =

as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, or (ii) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg as of the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;

(B) =

the Exercise Price of this Warrant, as adjusted hereunder; and

(X) =

the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

If Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised.  The Company agrees not to take any position contrary to this Section 2(c).

d)       Mechanics of Exercise.

Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earlier of (i) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company and (ii) the number of Trading Days comprising the Standard Settlement Period, in each case following the delivery of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received by the Warrant Share Delivery Date. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the third (3^rd) Trading Day after the Warrant Share Delivery Date) for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise.

Notwithstanding the foregoing, with respect to any Notice(s) of Exercise delivered on or prior to 4:00 p.m. (New York City time) on the Trading Day immediately prior to the Initial Exercise Date, the Company agrees to deliver the Warrant Shares subject to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date and the Initial Exercise Date shall be the Warrant Share Delivery Date for purposes hereunder, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received by such Warrant Share Delivery Date.⁴

ii.            Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii.            Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

⁴ This provision shall only apply if Stockholder Approval is not required for the exercise of the Warrants.

iv.            Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

v.            No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

vi.            Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

vii.            Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

e)       Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability for exercises of this Warrant that are not in compliance with the Beneficial Ownership Limitation, provided this limitation of liability shall not apply if the Holder has detrimentally relied on outstanding share information provided by the Company or the Transfer Agent. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, and the Company shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability for exercises of the Warrant that are not in compliance with the Beneficial Ownership Limitation, except to the extent the Holder relies on the number of outstanding shares of Common Stock that was provided by the Company. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within one (1) Trading Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be [4.99%/9.99%] of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61^st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

Section 3.         Certain Adjustments.

a)       Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b)       Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

c)       Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, that to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

d)       Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company (or any Subsidiary), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of the Company’s assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of greater than 50% of the outstanding Common Stock and greater than 50% of the voting power of the common equity of the Company, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires greater than 50% of the outstanding shares of Common Stock and greater than 50% of the voting power of the common equity of the Company (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction; provided, however, that if the Fundamental Transaction is not within the Company's control, including not approved by the Company's Board of Directors, the Holder shall only be entitled to receive from the Company or any Successor Entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of the Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction; provided, further, that if holders of Common Stock of the Company are not offered or paid any consideration in such Fundamental Transaction, such holders of Common Stock will be deemed to have received common stock of the Successor Entity (which Successor Entity may be the Company following such Fundamental Transaction) in such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black-Scholes Option Pricing Model obtained from the “OV” function on Bloomberg determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable contemplated Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the 100 day volatility obtained from the HVT function on Bloomberg (determined utilizing a 365 day annualization factor) as of the Trading Day immediately following the public announcement of the applicable contemplated Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable contemplated Fundamental Transaction and the Termination Date and (E) a zero cost of borrow. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds (or such other consideration) within the later of (i) five Trading Days of the Holder’s election and (ii) the date of consummation of the Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall be added to the term “Company” under this Warrant (so that from and after the occurrence or consummation of such Fundamental Transaction, each and every provision of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to each of the Company and the Successor Entity or Successor Entities, jointly and severally), and the Successor Entity or Successor Entities, jointly and severally with the Company, may exercise every right and power of the Company prior thereto and the Successor Entity or Successor Entities shall assume all of the obligations of the Company prior thereto under this Warrant and the other Transaction Documents with the same effect as if the Company and such Successor Entity or Successor Entities, jointly and severally, had been named as the Company herein. For the avoidance of doubt, the Holder shall be entitled to the benefits of the provisions of this Section 3(d) regardless of (i) whether the Company has sufficient authorized shares of Common Stock for the issuance of Warrant Shares and/or (ii) whether a Fundamental Transaction occurs prior to the Initial Exercise Date.

e)        Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

f)        Notice to Holder.

i.        Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii.       Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company (or any of its Subsidiaries) is a party, any sale or transfer of all or substantially all of its assets, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by email to the Holder at its last email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4.         Transfer of Warrant.

a)       Transferability. This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b)       New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

c)        Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section 5.         Miscellaneous.

a)       No Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.

b)       Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c)       Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Trading Day, then, such action may be taken or such right may be exercised on the next succeeding Trading Day.

d)       Authorized Shares.

 The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

 Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

 Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e)       Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. The Company and, by accepting this Warrant, the Holder each agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Warrant (whether brought against the Company or the Holder or their respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. The Company and, by accepting this Warrant, the Holder each hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. The Company and, by accepting this Warrant, the Holder each hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to it at the address in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If the Company or the Holder shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

f)        Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

g)       Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding the fact that the right to exercise this Warrant terminates on the Termination Date. Without limiting any other provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

h)       Notices. Any and all notices or other communications or deliveries to be provided by the holders hereunder including, without limitation, any Notice of Exercise, shall be in writing and delivered personally, by e-mail, or sent by a nationally recognized overnight courier service, addressed to the Company, at [ ], Attention: [ ], [ ], email address: [ ], or such other email address or address as the Company may specify for such purposes by notice to the Holders. Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by e-mail, or sent by a nationally recognized overnight courier service addressed to the Holder at the e-mail address or address of the Holder appearing on the books of the Company. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the time of transmission, if such notice or communication is delivered via e-mail at the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next Trading Day after the time of transmission, if such notice or communication is delivered via e-mail at the e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent that any notice provided by the Company hereunder constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.

i)         Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

j)        Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k)       Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

l)        Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company, on the one hand, and the Holder of this Warrant, on the other hand.

m)      Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n)       Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.
