About

This is a prospective, multicenter, randomized, open-label, phase III trial evaluating the efficacy and safety of azacitidine plus venetoclax versus azacitidine alone as maintenance therapy in patients with acute myeloid leukemia (AML) who have achieved first complete remission (CR) or CR with incomplete count recovery (CRi) after induction and consolidation. Eligible patients aged 14 to 74 years are randomized 1:1 to receive either azacitidine 50 mg/m²/day on days 1-5 every 6 weeks for up to 12 cycles, or the same azacitidine regimen combined with venetoclax 400 mg on days 1-7 per cycle. The primary endpoint is disease-free survival (DFS). Secondary endpoints include overall survival (OS), relapse-free survival (RFS), cumulative incidence of relapse (CIR), minimal residual disease (MRD) conversion rate, and safety. A total of 788 patients are planned with stratification by prior venetoclax exposure and MRD status.

Enrollment: 788 estimated patients
