Time frame
From randomization until the primary analysis cut-off date of February 15 2019; the median follow-up time was 12.0 months (range: 0.2-17.0) in the placebo arm and 12.0 months (range: 0.1-17.6) in the venetoclax arm.

What was measured

Overall survival is defined as the time from the date of randomization to the date of death. Participants who had not died were censored at the date they were last known to be alive on or before the cutoff date. Overall survival was analyzed using Kaplan-Meier methodology.

Analysis population: The full analysis set included all randomized participants.

Groups in this outcome

Placebo + Low Dose Cytarabine (LDAC)

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.

Venetoclax + Low Dose Cytarabine (LDAC)

Participants received venetoclax 600 mg orally once a day plus cytarabine 20 mg/m² subcutaneously on Days 1 to 10 of each 28-day cycle.
