Overview
Brief Summary
The study is designed as a Phase III, multicenter trial comparing outcomes after allogeneic hematopoietic stem cell transplantation (HCT) for acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) between patients receiving myeloablative conditioning (MAC) versus reduced intensity conditioning (RIC) regimens.
Detailed Description
Patients randomized to RIC will receive one of two regimen types: the combination of fludarabine (120-180 mg/m\^2) and busulfan (less than or equal to 8 mg/kg or IV equivalent) (Flu/Bu) or fludarabine (120-180 mg/m\^2) and melphalan (less than 150 mg/m\^2) (Flu/Mel). Patient randomized to MAC will receive one of three regimens: busulfan (16 mg/kg oral or 12.8 mg/kg IV equivalent) and cyclophosphamide (120 mg/kg) (Bu/Cy); or, busulfan (16 mg/kg PO or 12.8 mg/kg IV) and fludarabine (120-180 mg/m\^2) (Bu/Flu); or, cyclophosphamide (120 mg/kg) and total body irradiation (greater than 1200-1420cGy) (CyTBI). A total of 356 patients (178 to each arm) will be accrued on this study over a period of four years. Patients will be followed for up to 18 months from transplantation.
