Resumen
Fecha de inicio: 1 de septiembre de 1998
Fecha en la que se inscribió al primer participante.OBJECTIVES: I. Evaluate the incidence of acute graft versus host disease in patients undergoing transplantation with an unrelated or related matched or mismatched antigen donor. II. Evaluate the rapidity of engraftment and CD4 count recovery post-transplantation in this patient population. OUTLINE: Patients receive total body irradiation (TBI) three or two times a day on days -8 to -5. Following TBI, patients receive thiotepa IV over 4 hours daily on days -4 and -3 plus cyclophosphamide IV over 1 hour daily on days -2 and -1. Antithymocyte globulin is administered by IV over at least 4 hours on days -4 to -1. Patients undergo an allogenic bone marrow transplantation on day 0. Bone marrow is harvested from patient's donor, depleted of T-cells, and infused. Patients receive filgrastim (G-CSF) subcutaneously beginning on day 4. PROJECTED ACCRUAL: Approximately 26-45 patients will be accrued for this study within 3-4 years.
