PTGX Protagonist Therapeutics Inc

NEWARK, Calif., Nov. 6, 2019 /PRNewswire/ -- Protagonist Therapeutics, Inc. (Nasdaq:PTGX) today reported its financial results for the third quarter ended September 30, 2019, and provided a corporate update.

"The progress of our three clinical candidates shows the strength and versatility of the Protagonist peptide engineering platform," commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. "These maturing assets reflect our steady transition toward becoming a fully integrated company. In addition to the ongoing Phase 2 study in beta-thalassemia, we continue to explore the full potential of the hepcidin mimetic PTG-300 as one product with multiple clinical applications. We recently dosed the first patient in a Phase 2 open-label study for the potential treatment of polycythemia vera. We are on track to initiate a Phase 2 study with PTG-300 in hereditary hemochromatosis, and we expect an investigator sponsored study in myelodysplastic syndrome to begin in early 2020. In the portfolio of inflammatory bowel disease product candidates comprised of oral gut-restricted peptides, we plan to begin a Phase 2 study with the alpha-4-beta-7 integrin antagonist PN-943 in patients with ulcerative colitis in the second quarter of 2020, on the basis of a completed Phase 1 study. We also recently dosed the first patient in a Phase 2 study of oral interleukin-23 receptor antagonist PTG-200, partnered with Janssen Biotech, with results from this study expected in 2021. Finally, we continue to maintain a strong financial position, with available cash, investments and access to an established debt facility to support the development of pipeline assets through year-end 2021."

Product Development and Corporate Update:

PTG-300

• Preliminary Phase 2 results from the ongoing study of PTG-300 for the treatment of beta-thalassemia are expected in the fourth quarter of 2019.
• An abstract relating to pre-clinical studies of hepcidin mimetic PTG-300 has been accepted for presentation at the American Society for Hematology (ASH) Annual meeting, taking place Dec. 7-10 in Orlando, Fla.
• The Company is planning to initiate a Phase 2 study in patients with hereditary hemochromatosis, a third indication of development for PTG-300, by early 2020.
• An investigator-sponsored study of PTG-300 in patients with myelodysplastic syndromes, which represents a fourth potential indication for PTG-300, is expected to begin in early 2020.

PTG-943

• Protagonist announced results from the multiple ascending dose (MAD) part of the Phase 1 study of PN-943 with two weeks of daily administration, demonstrating sustained target engagement and additional confirmation of superior target engagement as compared with the first generation oral alpha-4-beta-7 integrin antagonist PTG-100.
• Clinical data from the Phase 1 study of oral alpha-4-beta-7 integrin antagonist PN-943 were presented at the American College of Gastroenterology (ACG) Annual Scientific Meeting.
• The Company plans to initiate a Phase 2 study of PN-943 for the treatment of ulcerative colitis in the second quarter of 2020.

PTG-200 (JNJ-67864238)

• Data from the Phase 1 study of PTG-200, an oral peptide IL-23 receptor antagonist partnered with Janssen Biotech, were recently presented at the United European Gastroenterology Week conference and the American College of Gastroenterology (ACG) Annual Scientific Meeting.
• The first patient has been dosed in a Phase 2 study of PTG-200 (also referenced as JNJ-67864238) in patients with moderate to severe Crohn's disease. Protagonist Therapeutics and Janssen Biotech are jointly conducting the development of PTG-200 through completion of Phase 2 clinical proof of concept in the treatment of Crohn's disease.

Financing

• During the third quarter of 2019, the Company issued 1.9 million shares through its at-the-market (ATM) program and raised $23.9 million, at an average price of $12.44 per share.

Financial Results

Protagonist reported a net loss of $16.4 million and $59.7 million, respectively, for the third quarter and first nine months of 2019, as compared to a net loss of $8.7 million and $25.1 million, respectively, for the same periods of 2018. The increase in net loss for the third quarter of 2019 as compared to the prior year period was driven primarily by increased research and development (R&D) costs related to advancing its products in various clinical trials. The increase in net loss for the first nine months of 2019 as compared to the prior year period was driven primarily by the previously reported application of revenue accounting principles following the May 2019 Amendment to the Janssen collaboration agreement where the Company re-assessed overall timelines as well as re-estimated completed and remaining services, including a cumulative one-time adjustment of $9.4 million reported in the second quarter of 2019, and an increase in R&D costs related to advancing its products is various clinical trials. The net loss for the third quarter and first nine months of 2019 includes non-cash stock-based compensation of $2.2 million and $6.2 million, respectively, as compared to $2.0 million and $4.8 million, respectively, for the same periods of 2018.

R&D expenses for the third quarter and first nine months of 2019 were $17.3 million and $49.1 million, respectively, as compared to $12.1 million and $45.2 million, respectively, for the same periods of 2018. The increases in R&D expenses were primarily due to increased clinical development costs related to PTG-300 and PN-943, offset by lower cost related to pre-clinical and discovery expenses and other clinical development expenses.

General and administrative (G&A) expenses for the third quarter and first nine months of 2019 were $4.0 million and $11.6 million, respectively, as compared to $3.4 million and $10.2 million, respectively, for the same periods of 2018. The increases in G&A expenses were primarily due to increases in salaries and employee-related expenses driven by an increase in headcount and professional services expenses to support growth in operations.

Protagonist ended the third quarter with $137.7 million in cash, cash equivalents and marketable securities, and $10 million of the debt facility was funded at closing in October 2019. The Company expects cash, cash equivalents and marketable securities, and access to its debt facility will be sufficient to fund its planned operating and capital expenditures through year-end 2021.
