Busulfan Plus Cyclophosphamide vs Fludarabine as a Conditioning Regimen (BuCyvsBUFlu)

This study has been completed.

Cooperative Study Group A for Hematology Identifier:
First received: October 15, 2008
Last updated: February 10, 2011
Last verified: February 2011
  1. At the same time of registration, patients will be randomized to one of the two conditioning therapy groups; Arm I (intravenous busulfan plus cyclophosphamide; BuCy) or Arm II (intravenous busulfan plus fludarabine; BuFlu).
  2. Randomization will be a stratified permuted-block design. 2.1The patients will be stratified into standard risk vs. high risk group, and related vs. unrelated donor. Standard risk group will be defined as follows: patients with acute leukemia in first remission, CML in chronic phase, and MDS (RA or RARS categories). High risk group will be defined as follows: patients with acute leukemia in relapse or in second or subsequent remission, CML in accelerated or blastic phase, and MDS (CMMoL or RAEB categories).

2.2.Pre-assigned block size is 8.
