In this ALFA-9803 trial in AML patients aged 65 years or more, we randomly compared idarubicin or daunorubicin throughout the study (first randomization) and two different post-remission strategies (second randomization): one single intensive consolidation course similar to induction versus six ambulatory cycles with one dose of idarubicin/daunorubicin (day 1) and 2x60 mg/m2/d cytarabine SC (day 1 to 5) delivered in out-patients on a monthly basis. Primary endpoint was 2-year overall survival (OS). Study hypotheses were equivalence for the idarubicin/daunorubicin comparison and a 15% difference in 2-year OS for the post-remission therapy comparison.
