- Primary Outcome Measures
Name Time Method Primary objective:<br>Achieving an EFS, which is not inferior to the ML-DS 2006 trial: 5yr-EFS; 87±3%<br><br>Primary endpoint:<br>Event-free survival (EFS), defined as time from diagnosis to the first event or last follow-up. Events are death from any cause, failure to achieve remission, relapse, and secondary malignancy. Failure to achieve remission is considered as an event on day 0
- Secondary Outcome Measures
Name Time Method Secondary Objective:<br>• Reduction of toxicity: severe adverse events (CTCAE v4.0 grade III or higher)<br>• To evaluate the response rate<br>• Identification of prognostic factors (e.g. trisomy 8) concerning the risk of relapse, toxicity and poor outcome<br>• To evaluate the role of different methods in the determination of minimal residual disease measurement<br><br>Secondary Endpoint:<br>• Overall survival (OS), as defined as the time of diagnosis to death from any cause or last follow-up.<br>• Disease-free survival (DFS) <br>• Early Response Rate (CR, CRp, CRi) after induction<br>• Treatment-related mortality (TRM)<br>• Minimal residual disease (FACS and NGS) <br>• Adverse events (according to NCI CTCAE v4.0)<br>• Duration of myelosuppression (neutrophils < 0.5 Gpt/L).<br>
