The panelists discussed the dire need for new therapies for older patients with hematologic malignancies including acute myeloid leukemia (AML), and the curative role of bone marrow transplant. Iomab-B was described as having efficacy and safety superior to that of traditional myeloablative regimens, and likely to markedly increase the number of patients eligible for transplant. An update on the upcoming Phase 3 clinical trial of Iomab-B, plus clinical positioning and positive commercial prospects were also provided, and can be viewed online.

The meeting featured bone marrow transplant and hematology specialist Hillard M. Lazarus, MD, a Professor of Medicine at Case Western Reserve University (CWRU) School of Medicine, as well as Disease Team Leader and Director of Novel Cell Therapy at University Hospitals, Case Medical Center, and Company Scientific Advisory Board Member.

He has over 500 publications and has won a variety of lifetime achievement, distinguished alumnus, and cancer research awards, in addition to fellowships sponsored by the Leukemia Society of America and the American Cancer Society.

Dr. Turck was formerly the head of Bayer's Global Specialty Medicine business, where he helped lead the commercialization of Xofigo, the first alpha particle-emitting radioactive agent, whose launch has been the most commercially successful of any radiopharmaceutical product to date.

About Bone Marrow Transplant:
Bone marrow transplants (BMT) are most commonly used to treat leukemia and lymphoma, conditions incurred when a blood or immune cell, respectively, becomes cancerous and proliferates. Together, these diseases account for some 50,000 to 75,000 new cases annually in the United States. BMT involves first clearing a patient's body of his or her own immune cells and then transplanting bone marrow, the source of all blood- and immune-forming cells, from a tissue-matched donor. The new cells, which are free of cancer, repopulate the patient's bone marrow and eventually give rise to a functioning set of blood and immune cells, providing a lifelong cure. BMT offers the chance of a "curative" outcome (2+ year survival), and therefore can play a central role in the treatment of AML. The impact of BMT on AML continues to increase with AML being the most common and fastest growing indication for allogeneic BMT, comprising 25% to 30% of all BMT recipients. There are currently over 100,000 BMT survivors across all indications and this number is expected to increase to 250,000 by 2020 and 500,000 by 2030, with 25% of them over age 60.

About Iomab-B
Iomab-B™ is being developed to prepare patients for hematopoietic stem cell transplantation (HSCT) and will enter a single, pivotal Phase 3 clinical study in relapsed/refractory AML. Iomab-B is a radioimmunoconjugate consisting of BC8, a novel murine monoclonal antibody, and iodine-131 radioisotope. BC8 has been developed by Fred Hutchinson Cancer Research Center to target CD45, a pan-leukocytic antigen widely expressed on white blood cells. This antigen makes BC8 potentially useful in targeting white blood cells in preparation for hematopoietic stem cell transplantation 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).
