Time frame
Day 1 (randomization) to 40 months; date of the first documented CR or CRi until date of first documented relapse.

What was measured

The time from the date CR or CRi was first documented until the date of documented relapse from CR/CRi. Duration of remission was defined only for those participants who achieved a CR or CRi, as determined by the IRC. Participants who were lost to follow-up without documented relapse, or were alive at last follow-up without documented relapse were censored at the date of their last response assessment.

Analysis population: Includes those who achieved a CR or CRi and assessed by the IRC; numbers of ITT participants in each treatment group

Groups in this outcome

Azacitidine (AZA)

Azacitidine 75 mg/m2/day by subcutaneous injection \[SC\] for 7 days every 28 days, with a 21 day rest period (optimally for at least 6 cycles) plus best supportive care as needed, including antibiotics and blood product transfusions, growth factors, per physician's discretion.

Conventional Care Regimen

CCRs included: #1 Intensive Chemotherapy: Cytarabine 100-200 mg/m\^2 as a continuous intravenous infusion (CIVI) for 7 days and daunorubicin 45 to 60 mg/m\^² daily (QD) IV on Days 1, 2 and 3 or Idarubicin 9-12 mg/m\^² IV QD for 3 days. Consolidation Therapy (Cycle 2 and 3) = Cytarabine 100-200 mg/m\^2 as a CIVI for 3 to 7 days and daunorubicin 45 to 60 mg/m\^² QD or Idarubicin 9-12 mg/m\^² IV QD on Days 1 and 2. The first consolidation therapy started between Day 28 and Day 70 from start of induction therapy, upon recovery of absolute neutrophil count (ANC) above 1.0 x 10\^9/L and platelets above 75 x 10\^9/L. The second cycle started between Day 28 and Day 70 from start of first consolidation therapy. Best supportive care (BSC) of antibiotics and transfusions, were given as needed # 2 Low-dose cytarabine 20 mg subcutaneously twice a day (BID) for 10 days every 28 days, plus BSC # 3 BSC only = transfusion of blood products, antibiotics, antifungals and nutritional help
