Actinium Pharmaceuticals, Inc. (NYSE MKT:ATNM) ("Actinium" or "the Company"), a biopharmaceutical Company developing innovative targeted payload immunotherapeutics for the treatment of advanced cancers, announced today that the Company received clearance from Health Canada to initiate the pivotal Phase 3 SIERRA Trial of Iomab-B at Canadian based clinical trial sites. Iomab-B is Actinium’s lead asset that upon approval, is intended to prepare and condition patients for a bone marrow transplant (BMT), also referred to as a hematopoietic stem cell transplant (HSCT), which is often considered the only potential cure for patients with certain blood-borne cancers and blood disorders. The SIERRA trial is a 150-patient, randomized, multicenter pivotal study evaluating Iomab-B followed by an HSCT in patients with relapsed or refractory acute myeloid leukemia (AML) who are age 55 and above compared to physician’s choice of chemotherapy that patient’s in the control arm will receive.
According to the Canadian Blood and Marrow Transplant Group (CBMTG), there are approximately 15 centers in Canada that perform blood and marrow transplants who participate in the CBMTG’s registry. In CBMTG’s 2015/2016 annual report, it reported that there were 7,693 allogeneic transplants performed in Canada including 2,417 for patients with AML.
Dr. Mark Berger, Chief Medical Officer of Actinium said, “The clearance to initiate the SIERRA trial in Canada is an exciting milestone for Iomab-B as it offers us the opportunity to make Iomab-B available to more patients in need. We are expecting to open 15-20 clinical trial sites in the SIERRA trial and we are excited to begin to have participation from sites in Canada. The promise of Iomab-B is that it will enable a bone marrow transplant and long term survival for these patients that have few options for treatment.”
About Iomab-B
Iomab-B is Actinium’s lead product candidate that is currently being studied in a 150-patient, multicenter pivotal Phase 3 clinical trial in patients with relapsed or refractory acute myeloid leukemia who are age 55 and above. Upon approval, Iomab-B is intended to prepare and condition patients for a bone marrow transplant, also referred to as a hematopoietic stem cell transplant, which is often considered the only potential cure for patients with certain blood-borne cancers and blood disorders. Iomab-B targets cells that express CD45, a pan-leukocytic antigen widely expressed on white blood cells with the monoclonal antibody, BC8, labeled with the radioisotope, iodine-131. By carrying iodine-131 directly to the bone marrow in a targeted manner, Actinium believes Iomab-B will avoid the side effects of radiation on most healthy tissues while effectively killing the patient’s cancer and marrow cells. In a Phase 2 clinical study in 68 patients with advanced AML or high-risk myelodysplastic syndrome (MDS) age 50 and older, Iomab-B produced complete remissions in 100% of patients and patients experienced transplant engraftment at day 28. Iomab-B was developed at the Fred Hutchinson Cancer Research Center where it has been studied in almost 300 patients in a number of blood cancer indications, including acute myeloid leukemia (AML), chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), Hodgkin's disease (HD), Non-Hodgkin lymphomas (NHL) and multiple myeloma (MM). Iomab-B has been granted Orphan Drug Designation for relapsed or refractory AML in patients 55 and above by the U.S. Food and Drug Administration and the European Medicines Agency.
About Actinium Pharmaceuticals, Inc.
Actinium Pharmaceuticals, Inc. is a biopharmaceutical company developing innovative targeted therapies for patients with cancers lacking effective treatment options. Actinium's proprietary platform utilizes monoclonal antibodies to deliver radioisotopes directly to cells of interest in order to kill those cells safely and effectively. The Company's lead product candidate Iomab-B 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. Actinium believes 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. The Company is 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. The Company's second product 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. In addition, Actinium is developing Actimab-M, which is being studied in patients with relapsed or refractory multiple myeloma in a Phase 1 clinical trial. 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 cancers that are blood-borne or form solid tumors. Actinium Pharmaceuticals is based in New York, NY.
