The main objective of this study is to evaluate safety and efficacy of an active drug in combination with azacitidine (AZA) and best supportive care (BSC) compared to BSC as maintenance therapy in adult participants with acute myeloid leukemia (AML) in first remission after conventional chemotherapy. This study will be conducted in two parts. Part 1 will be the Dose Confirmation portion to determine recommended Phase 3 dose of an active drug in as maintenance therapy improves RFS comparing to BSC. Part 2 begins after Part 1 is completed. During this study, participants will receive an active drug and azacitidine or best supportive care for approximately 2 years with study visits varying from 1-5 per month.
