The company’s proprietary technology platform combines monoclonal antibodies with radioisotopes to deliver highly potent, cell‐killing radiation directly to cancer cells while sparing healthy tissues. Actinium’s lead product candidate, Iomab‐B, is being evaluated as a conditioning regimen for older patients with acute myeloid leukemia (AML) who are ineligible for standard bone marrow transplants. In addition to Iomab‐B, Actinium’s pipeline includes Actimab‐A, an anti‐CD33 antibody labeled with the radioisotope bismuth‐213 for the treatment of relapsed or refractory AML. The company also has exploratory programs leveraging its antibody‐targeted alpha‐conjugate (ATAC) platform in other hematologic and solid tumor indications. These programs are designed to advance precision oncology by combining the targeting specificity of antibodies with the high‐energy, short‐range properties of alpha‐emitting isotopes. Actinium collaborates with leading academic research institutions to advance its clinical programs, and its development strategy is supported by orphan drug designations and fast‐track status from regulatory authorities. The company is incorporated in Delaware, headquartered in New York City, and conducts clinical trials primarily in the United States. Its management team brings expertise in oncology drug development, radiochemistry, and regulatory affairs to drive its late‐stage assets toward potential commercialization.AI Generated.
