  1. description
    Participants received matching placebo to venetoclax orally once a day (QD) plus cytarabine 20 mg/m² subcutaneously on Days 1 to 10 of each 28-day cycle. Participants continued treatment until documented disease progression, unacceptable toxicity, withdrawal of consent, or other protocol criteria for discontinuation were met.

    Overall Study
pre Assignment Details
Participants with acute myeloid leukemia (AML) were randomized to one of two treatment arms in a 1:2 ratio (placebo + low-dose cytarabine \[LDAC\] or venetoclax + LDAC). Randomization was stratified by AML status (secondary, de novo), age (18 - \< 75, ≥ 75) and region (United States \[US\], European Union \[EU\], China, Japan, rest of world).
recruitment Details
Participants were enrolled at 76 sites globally. The study is currently ongoing; the results reported below include the primary analysis for efficacy which was conducted after 133 deaths occurred (data cut-off date of 15 February 2019), and an unplanned 6-month follow-up update for overall survival and safety (15 August 2019 cut-off date).
