Donor Stem Cell Transplant With Treosulfan, Fludarabine, and Total-Body Irradiation for the Treatment of Hematological Malignancies

Is NCT04195633 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies multiple treatments for acute leukemia.

Phase 2RecruitingFred Hutchinson Cancer CenterNCT04195633Data as of May 2026

Treatment: Cyclophosphamide · Cyclosporine · Filgrastim · Fludarabine · Mycophenolate Mofetil · Mycophenolate Sodium · TreosulfanThis 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.
