Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) is a pioneering biopharmaceutical company focused on developing targeted radiotherapies for treating cancer. Founded with the mission of improving survival outcomes for patients with difficult-to-treat cancers, Actinium leverages its proprietary Antibody Radiation Conjugates (ARCs) to deliver potent radiation directly to cancer cells while sparing healthy tissue.

Actinium's leading candidates include Iomab-B and Actimab-A. Iomab-B is a radioimmunotherapy intended for conditioning before bone marrow transplants in patients with active relapsed or refractory acute myeloid leukemia (r/r AML). The pivotal Phase 3 SIERRA trial has demonstrated Iomab-B's ability to significantly improve overall survival and remission rates, particularly in patients with the high-risk TP53 mutation. Advanced filings for Biologics License Application (BLA) and Marketing Authorization Application (MAA) are underway.

Actimab-A, targeting CD33, is being developed as a therapeutic for r/r AML and is currently progressing under the National Cancer Institute’s CRADA pivotal development path. This candidate, along with Iomab-B, has shown promising results in overcoming genetic mutations and providing high response rates.

In addition to its robust pipeline, Actinium is actively involved in partnerships to extend its technology platform to solid tumors. Notable collaborations include those with Astellas Pharma, AVEO Oncology, and LG Chem Life Sciences. The company holds an extensive intellectual property portfolio with over 230 patents and patent applications.

Recent developments include the initiation of a clinical trial for Iomab-ACT, a next-generation conditioning agent for cell and gene therapies such as CAR T-cell therapy. This trial, led by the University of Texas Southwestern Medical Center, aims to replace traditional chemotherapy conditioning with targeted radiotherapy to reduce toxicities and improve patient outcomes.

Actinium’s strong presence at major scientific conferences such as the American Society of Hematology (ASH), European Bone Marrow Transplant Society (EBMT), and Tandem Meetings of ASTCT and CIBMTR underscores its commitment to advancing targeted radiotherapies and highlights the potential of its innovative treatments in transforming cancer care.

Rhea-AI Summary
Actinium Pharmaceuticals presented data at the Society of Immunotherapy of Cancer (SITC) 38th Annual Meeting, highlighting Actimab-A's ability to target and deplete myeloid-derived suppressor cells (MDSCs) in solid tumors. The data showed that Actimab-A reduced cancer patient-derived MDSCs and restored T cell proliferation and effector function. In addition, Actimab-A significantly depleted MDSCs in tumor-bearing humanized mice. The company believes that Actimab-A has the potential to be used in combination with immunotherapy to enhance antitumor immunity.
