Actinium Expands Clinical Leadership Team to Support Key Development Programs for Iomab-B and Actimab-A

• Key hires with proven expertise and track records in Bone Marrow Transplant, Acute Myeloid Leukemia, Radiation Sciences and Clinical Operations position Actinium well to drive key clinical programs forward

NEW YORK, Oct. 27, 2022 /PRNewswire/ -- Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) (Actinium or the Company), a leader in the development of targeted radiotherapies, today announced a broad senior level expansion of its clinical organization.  These key hires strengthen the Company's expertise in hematological malignancies, bone marrow transplant (BMT) and radiation sciences as well its operational capabilities. The addition of Madhuri Vusirikala, MD, Vice President of Clinical Development, BMT and Cellular Therapy, and Akash Nahar, MD, Vice President of Clinical Development, are complemented by the deep nuclear medicine and radiation science expertise with Patrik Brodin, Ph.D., Vice President of Radiation Sciences. Elaina Haeuber, Vice President, Head of Clinical Operations, will lead the clinical operations organization to further support the Company's clinical development plans for its pipeline products including Iomab-B and Actimab-A.

Dr. Avinash Desai, Chief Medical Officer at Actinium, said, "We are excited to add these talented and accomplished leaders to Actinium. This seasoned team bolsters our capabilities across the board as we advance our clinical development programs with Iomab-B, Actimab-A and Iomab-ACT. The expertise and contributions of these most recent additions to the team will be valuable as we continue the development of these highly differentiated product candidates in BMT, cell and gene therapy conditioning, as well as hematologic therapeutics. I look forward to working with our expanded team to unlock the full potential of our clinical portfolio."

Dr. Madhuri Vusirikala stated, "As a transplant physician, I know far too well the challenges in managing patients with relapsed or refractory AML and the frustration in not being able to offer potentially curative BMT to these patients. Iomab-B has the opportunity to significantly expand access to BMT for patients with AML and several other hematologic malignancies. This product candidate has the potential to shorten and improve the patient journey and the way we manage these patients in pursuit of increased survival and even curative outcomes. I am excited to bring to bear my expertise in the continued development and expansion of Iomab-B and Iomab-ACT".  Dr. Akash Nahar added, "AML is an aggressive disease and despite 9 drug approvals since 2017, outcomes for relapsed or refractory patients remain dismal and a BMT remains the only curative option. As a hematologist, I believe both of Actinium's Iomab-B and Actimab-A clinical programs are highly differentiated. Having led many later stage development programs and regulatory filing efforts, I am excited by the opportunity to contribute my expertise as part of the Actinium team at this important point in the Company's evolution."

As previously announced, Actinium is preparing to report topline data from its pivotal Phase 3 SIERRA trial for Iomab-B in the fourth quarter of this year.

About Actinium Pharmaceuticals, Inc.

Actinium Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company developing targeted radiotherapies to deliver cancer-killing radiation with cellular level precision to treat patients with high unmet needs. Actinium's clinical pipeline is led by radiotherapies that are being applied to targeted conditioning, which is intended to selectively deplete a patient's disease or cancer cells and certain immune cells prior to a bone marrow transplant (BMT), gene therapy or adoptive cell therapy, such as CAR-T, to enable engraftment of these transplanted cells with minimal toxicities. Our lead product candidate, I-131 apamistamab (Iomab-B) has been studied in over four hundred patients, including the pivotal Phase 3 Study of Iomab-B in Elderly Relapsed or Refractory Acute Myeloid Leukemia (SIERRA) trial for BMT conditioning. Topline data from the SIERRA trial are expected in the fourth quarter of 2022. Iomab-ACT, low dose I-131 apamistamab, is being studied as a targeted conditioning agent in a Phase 1 study with a CD19 CAR T-cell Therapy with Memorial Sloan Kettering Cancer Center with NIH funding. Actimab-A, our second most advanced product candidate has been studied in approximately 150 patients with Acute Myeloid Leukemia or AML, including in ongoing combination trials with the chemotherapy regimen CLAG-M and with venetoclax, a targeted therapy. Actimab-A or lintuzumab-Ac225 is an Actinium-225 based antibody radiation conjugate targeting CD33, a validated target in AML.  Actinium is a pioneer and leader in the field of Actinium-225 alpha therapies with an industry leading technology platform comprising over 190 patents and patent applications including methods of producing the radioisotope AC-225. Our technology and expertise have enabled collaborative research partnerships with Astellas Pharma, Inc. for solid tumor theranostics, with AVEO Oncology Inc. to create an Actinium-225 HER3 targeting radiotherapy for solid tumors, and with EpicentRx, Inc. to create targeted radiotherapy combinations with their novel, clinical stage small molecule CD47-SIRPα inhibitor.
