Official Title: A Phase II Study Evaluating Selective Depletion of CD45RA+ T Cells From Allogeneic Peripheral Blood Stem Cell Grafts From HLA-Matched Related and Unrelated Donors for Prevention of GVHD
Brief Summary: This phase II trial studies how well selective T cell depletion works in preventing graft-versus-host disease (GVHD) in patients with acute lymphocytic leukemia, acute myeloid leukemia, or chronic myelogenous leukemia undergoing donor peripheral blood stem cell transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing a subset of the T cells from the donor cells before transplant may stop this from happening.
