Item 7.01 Regulation FD Disclosure.
On February 18, 2023, Actinium Pharmaceuticals,
Inc. (the “Company”), announced that Iomab-B met the primary endpoint of the pivotal Phase 3 SIERRA trial producing higher
rates of durable Complete Remission (“dCR”) 6-months following initial complete remission after bone marrow transplant (“BMT”)
with high statistical significance (p<0.0001). Iomab-B also significantly improved event-free survival (“EFS”), a secondary
endpoint of the SIERRA trial, for which Iomab-B produced a 78% lower probability of an event resulting an EFS Hazard Ratio=0.22 (p<0.0001).
Patients receiving Iomab-B had a 100% increase in 1-year overall survival (“OS”) and median OS compared to patients on the
control arm. Overall survival is a secondary endpoint of the SIERRA trial, but the crossover arm of the SIERRA trial confounds statistics.
Patients receiving Iomab-B who reached 6-month dCR had long-term survival outcomes with 92% 1-year OS and 60 2-year OS. Iomab-B was well
tolerated based on the targeted nature, resulting in four times lower rates of sepsis in patients receiving Iomab-B compared to the control
arm and clinically meaningful lower rate of graft versus host disease (“GVHD”).
These results were presented at the 2023 Tandem
Meetings: Transplantation and Cellular Therapy Meetings of the American Society for Transplantation and Cellular Therapy (ASTCT) and the
Center for International Blood & Marrow Transplant Research (CIBMTR) in a late-breaker presentation on Saturday, February 18, 2023.
Also on February 18, 2023, the Company hosted an investor conference call and presented the results of the SIERRA trial as well as the
potential market and commercial opportunity for Iomab-B.
The Company issued a press release detailing these
results, a copy of which is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated by reference herein.
The Company also made an investor presentation detailing the same results, a copy of which is furnished as Exhibit 99.2 to this Current
Report on Form 8-K and is incorporated by reference herein. The Company undertakes no obligation to update, supplement or amend the materials
attached hereto as Exhibit 99.1 and 99.2
In accordance with General Instruction B.2 of
Form 8-K, the information in this Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1 and Exhibit 99.2,
shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under
the Exchange Act or the Securities Act of 1933, as amended, except as shall be expressly set forth by reference in such a filing. Furthermore,
the furnishing of information under Item 7.01 of this Current Report on Form 8-K is not intended to constitute a determination
by the Company that the information contained herein, including the exhibits hereto, is material or that the dissemination of such information
is required by Regulation FD.
