"Based on the DMC’s unanimous recommendation, we are pleased that the ongoing SIERRA trial will continue as planned," said Dr. Mark Berger, Chief Medical Officer of Actinium. "This is an important milestone for Iomab-B since it is the first formal safety evaluation of the trial. We note that no Iomab-B safety concerns were raised. With new insights from the data available from the trial thus far as well as feedback from the trial sites, we will make certain protocol revisions to further expand salvage regimens in the control arm. We’ll also be making it easier for patients on the Conventional Care arm who have disease progression to access Iomab-B treatment. In addition, we will be simplifying certain data collection requirements. These improvements coupled with our deeper understanding of referral patterns and other outreach efforts, are anticipated to enable the recently strengthened SIERRA clinical team to complete the trial as quickly as possible with the goal of bringing Iomab-B to a patient population with a significant unmet need."
Sandesh Seth, Actinium’s Chairman and CEO added, "Iomab-B is a very compelling drug candidate that has been studied in over 500 patients in multiple hematologic malignancies including AML, myelodysplastic syndrome, lymphoma and multiple myeloma and is intended to facilitate a potentially curative bone marrow transplant. Iomab-B was developed by the Fred Hutchinson Cancer Research Center in collaboration with the National Cancer Institute and has been studied extensively by leading bone marrow transplant physicians. We are incredibly proud of the pedigree of Iomab-B and motivated by its potential to address unmet medical needs as a targeted conditioning agent in multiple hematologic diseases. We believe that Iomab-B via the SIERRA trial can be the linchpin for developing the leading franchise in targeted conditioning with an emphasis on improving bone marrow transplant access and outcomes."
About Iomab-B
Iomab-B, Actinium’s lead targeted conditioning product candidate, 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. This pivotal Phase 3 study is called the SIERRA Trial (Study of Iomab-B in Elderly Relapsed/Refractory AML). Upon approval, Iomab-B is intended to prepare and condition patients for a bone marrow 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, an antigen widely expressed in the hematopoietic system on all leukemic and lymphomic (white blood cells), bone marrow cells and cancer stem cells with the monoclonal antibody, BC8 or apamistamab, 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 that conventional treatments such as chemotherapy and radiation has on most healthy tissues while effectively killing the patient’s cancer and marrow cells potentially enabling more bone marrow transplants with better outcomes through targeted conditioning. In a Phase 2 clinical study in 68 patients with advanced AML or high-risk myelodysplastic syndrome (MDS) age 50 and older, who typically would not be transplant candidates, were able to receive a transplant after being conditioned with Iomab-B and the study resulted in significantly improved transplant success and survival. Iomab-B was developed at the Fred Hutchinson Cancer Research Center where it has been studied in almost 500 patients in a number of Phase 1 and Phase 2 clinical trials across a variety of blood cancer indications with promising results. The studies included patients with 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.
