Hematopoietic Stem Cell Transplantation From Haploidentical Donors in Patients With Hematological Malignancies Using a Treosulfan-Based Preparative Regimen
Fred Hutchinson Cancer Center
Summary
This phase II trial studies how well a donor stem cell transplant, treosulfan, fludarabine, and total-body irradiation work in treating patients with blood cancers (hematological malignancies). Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps 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. 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. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.
Description
OUTLINE: Patients are assigned to 1 of 2 arms. ARM A (HIGH DOSE TREOSULFAN): Patients receive high dose treosulfan intravenously (IV) over 120 minutes on days -6 to -4 and fludarabine IV over 60 minutes on days -6 to -2. Patients then undergo total-body irradiation on day -1 and allogeneic hematopoietic stem cell transplantation on day 0. Patients then receive cyclophosphamide IV over 1-2 hours on days 3-4. Beginning on day 5, patients receive cyclosporine IV twice daily (BID) or three times daily (TID) over 1-2 hours or orally (PO) (after 3 months, in the absence of GVHD, cyclosporine taperi…
