Primary Objective: The primary objective is to compare two-year survival probabilities between patients in the two study arms using an intent-to-treat analysis.
Secondary Objectives: Patients randomized to the two study arms and actually transplanted will be compared for the following endpoints (patients who do not receive a transplant will be excluded from the following analyses): survival, incidences of neutrophil and platelet engraftment, graft failure, acute graft-versus-host disease (GVHD), chronic GVHD, time off all immunosuppressive therapy, relapse, infections, adverse events, immune reconstitution, and quality of life. Donors in each arm of the study will be compared for time to return to baseline functional score, toxicity score, and CBC and WBC differential values after donation and quality of life. |
