Actinium Pharmaceuticals, Inc. (NYSE MKT:ATNM) is a publicly traded biopharmaceutical company developing innovative targeted therapies for patients with cancers lacking effective treatment options. Actinium's proprietary technology platform utilizes monoclonal antibodies to deliver radioisotopes directly to cells of interest in order to kill those cells both safely and effectively.
Actinium's lead product candidate, Iomab-B, is licensed from the Fred Hutchinson Cancer Research Center and is designed to be used, upon approval, in preparing patients for a hematopoietic stem cell transplant, commonly referred to as bone marrow transplant. A bone marrow transplant is often the only potential cure for patients with blood-borne cancers but the current standard preparation for a transplant requires chemotherapy and/or total body irradiation that result in significant toxicities. We believe Iomab-B will enable a faster and less toxic preparation of patients seeking a bone marrow transplant, leading to increased transplant success and survival rates. We are currently conducting a single pivotal 150-patient, multicenter Phase 3 clinical study of Iomab-B in patients with relapsed or refractory acute myeloid leukemia (AML) age 55 and older. Learn more about Iomab-B and bone marrow transplant for AML here.
Actinium is also developing Actimab-A, our lead alpha-particle drug candidate. Actimab-A is currently in a multicenter open-label, 53-patient Phase 2 trial for patients newly diagnosed with AML age 60 and over. Actimab-A is being developed to induce remissions in elderly patients with AML who lack effective treatment options and often cannot tolerate the toxicities of standard frontline therapies. Learn more about Actimab-A here.
In addition, Actinium has expanded its alpha-particle approach to include newly created drug candidate Actimab-M, which is being studied in patients with relapsed or refractory multiple myeloma in a Phase 1 clinical trial. Learn more about Actimab-M and the multiple myeloma trial here.
Actinium is also utilizing its alpha-particle immunotherapy (APIT) technology platform to generate new drug candidates based on antibodies linked to the element actinium-225 that are directed at various blood-borne or solid cancers.
