Reduced Intensity Haploidentical Transplant for Hematological Malignancies

Many patients with hematological malignancies (leukemia, lymphoma, multiple myeloma) cannot undergo hematopoietic stem cell transplantation (HSCT) because they do not have a well matched donor. HSCT from partially matched family donors (haploidentical HSCT) is an option for most patients but has been associated with poor outcomes. This study was designed to test whether using an exact amount of a donor's lymphocytes (white cells) and dividing the transplant process into 2 steps, would increase overall survival by decreasing complications. The therapy is reduced intensity so it is targeted, but not limited to, patients over the age of 65 or those who have had previous transplants.
