Primary Outcome Measures
NameTimeMethod
Group A:<br>Primary endpoint is Event Free Survival (EFS).<br><br>Group B: <br>The primary endpoint is Overall Survival (OS). OS is defined as the time from inclusion to death from any cause. Survivors will be censored at the date of the last follow-up evaluation.<br><br>Group C: A composite endpoint will be used as primary endpoint. Graft-versus host disease, VOD, Relapse Free Survival (GVRDS) is defined as the time from randomization to first failure event.<br>
