The main objective of this study is to evaluate the efficacy of venetoclax in combination with azacitidine to improve Relapse Free Survival (RFS) in AML patients compared to Best Supportive Care (BSC) when given as maintenance therapy following allogeneic stem cell transplantation (SCT). This study will have 2 parts: Part 1 (Dose Confirmation), which may include participants who are greater than or equal to 18 years old; Part 2 (Randomization) which may include participants who are greater than or equal to 12 years old. During Part 1, recommended Phase 3 dose of venetoclax in combination with azacitidine will be determined and during Part 2, the efficacy and safety of venetoclax with azacitidine (Part 2 Arm A) will be compared with BSC (Part 2 Arm B).
