- Actinium Pharmaceuticals, Inc. operates as a clinical-stage biopharmaceutical firm, dedicated to the advancement and commercialization of precision oncology treatments, including those for bone marrow transplantation, cell and gene therapies, and various adoptive cell approaches. Its leading therapeutic candidate, Iomab-B (I-131 apamistamab), an induction and conditioning agent for transplant, demonstrated positive primary endpoint results in the pivotal Phase 3 SIERRA trial for older patients with relapsed or refractory acute myeloid leukemia; however, the U.S. FDA has since requested further data demonstrating an overall survival benefit in an additional randomized clinical trial for Biologics License Application submission in the U.S.. Actinium is also advancing Actimab-A, a CD33-targeted therapeutic leveraging the alpha-emitter Actinium-225, positioned as a potential foundational therapy for acute myeloid leukemia and other myeloid conditions, with a pivotal Phase 2/3 study underway and additional research collaborations, including with Memorial Sloan Kettering Cancer Center, exploring novel combinations. The company's pipeline further encompasses ATNM-400, a first-in-class Actinium-225 radiotherapy targeting non-PSMA receptors for solid tumors like prostate, breast, and lung cancers, which has shown compelling preclinical efficacy. Other programs utilize diverse radioisotopes, such as Actinium-225 and Iodine-131, for targeted conditioning in cellular and gene therapies, exemplified by Iomab-ACT, and as standalone cancer treatments or in combination regimens. Actinium also distinguishes itself with proprietary cyclotron-based manufacturing technology for Actinium-225, aiming to establish a scalable and cost-effective supply of this critical isotope. Strategic alliances include a licensing agreement with Immedica Pharma AB for Iomab-B commercialization in Europe, the Middle East, and North Africa. Incorporated in 2000, the company maintains its headquarters in New York, New York.
