About this study

This phase I/II trial studies the best dose of total body irradiation with astatine-211 BC8-B10 monoclonal antibody for the treatment of patients with nonmalignant diseases undergoing hematopoietic cell transplant. Radiation therapy uses high energy gamma rays to kill cancer cells and shrink tumors. Astatine-211-labeled BC8-B10 monoclonal antibody is a monoclonal antibody, called anti-CD45 monoclonal antibody BC8-B10, linked to a radioactive/toxic agent called astatine 211. Anti-CD45 monoclonal antibody BC8-B10 is attached to CD45 antigen positive cancer cells in a targeted way and delivers astatine 211 to kill them. Giving astatine-211 BC8-B10 monoclonal antibody and total-body irradiation before a donor stem cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells.
