What was measured

OS is defined as the number of days from the date of randomization to the date of death. Log rank test was used to compare the OS distribution between two treatment arms. Cox regression was used to report the hazard ratio.

Analysis population: Full Analysis Set included all Group 2 participants randomized by IVRS/IWRS (exclude the open-label China safety cohort).

Groups in this outcome

Group 2: Placebo + Azacitidine 75 mg/m^2

Participants received venetoclax-matching placebo, orally, QD, from Day 1 to Day 28 of each 28 day cycle along with azacitidine 75 mg/m\^2, SC or IV, QD for 7 days from Day 1 of each 28-day cycle until documented disease progression, unacceptable toxicity, withdrawal of consent, or other protocol criteria for discontinuation (whichever occurred first).

Group 2: Venetoclax 100 mg/200 mg/400 mg + Azacitidine 75 mg/m^2

Participants received venetoclax 100 mg, once orally, on Day 1 of Cycle 1 followed by venetoclax 200 mg, once orally, on Day 2 of Cycle 1 and venetoclax 400 mg, orally, QD, from Day 3 to Day 28 of each 28-day cycle along with azacitidine 75 mg/m\^2, SC or IV, QD for 7 days from Day 1 of each 28-day cycle until documented disease progression, unacceptable toxicity, withdrawal of consent, or other protocol criteria for discontinuation (whichever occurred first).
