VA Consolidation in Intermediate-Risk AML

August 4, 2026 updated by: CHEN Jia, The First Affiliated Hospital of Soochow University

A Prospective, Randomized, Open-Label Study of Venetoclax Combined With Azacitidine for Consolidation Therapy in Adult Intermediate-Risk Acute Myeloid Leukemia

This clinical trial aims to compare the efficacy and safety of venetoclax-based consolidation therapy versus conventional consolidation chemotherapy (intermediate/high-dose cytarabine) in newly diagnosed adult patients with intermediate-risk acute myeloid leukemia (AML). Participants must have achieved complete remission (CR) or CR with incomplete hematologic recovery (CRi) after induction therapy with venetoclax and azacitidine and are planned to undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Detailed Description

The goal of this prospective, randomized, open-label, multi-center study is to demonstrate that consolidation therapy with venetoclax + azacitidine (VA) is non-inferior to conventional intensive chemotherapy (cytarabine-based regimens) in this specific patient population, while offering a more favorable safety profile.Eligible patients will be randomized 1:1 to receive either 1-2 cycles of VA (Venetoclax 400mg d1-28 + Azacitidine 75mg/m² d1-7) or 1-2 cycles of intermediate/high-dose cytarabine (AraC) ± anthracycline. The primary endpoint is 2-year Leukemia-Free Survival (LFS). Secondary endpoints include pre-transplant MRD-negative rate, Overall Survival (OS), Cumulative Incidence of Relapse (CIR), Non-Relapse Mortality (NRM), and safety profile (CTCAE v5.0). This study will provide high-level evidence for consolidation therapy in intermediate-risk AML in the venetoclax era.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Venetoclax + Azacitidine Consolidation

Venetoclax: 400 mg, orally, once daily on Days 1-28. (Dose adjustment required per prescribing information/guidelines when combined with CYP3A4 inhibitors).

Azacitidine: 75 mg/m²/day, subcutaneously or intravenously, on Days 1-7. Patients will receive 1-2 cycles of this regimen before proceeding to allo-HSCT.
Drug: Venetoclax and Azacitidine

Venetoclax: 400 mg, orally, once daily on Days 1-28. (Dose adjustment required per prescribing information/guidelines when combined with CYP3A4 inhibitors).

Azacitidine: 75 mg/m²/day, subcutaneously or intravenously, on Days 1-7. Patients will receive 1-2 cycles of this regimen before proceeding to allo-HSCT.
Active Comparator: Conventional Consolidation Chemotherapy

Cytarabine (AraC): ≥6g/m² per cycle (e.g., 1-2g/m², every 12 hours on days 1-3), administered intravenously.

May be combined with anthracycline/anthraquinone agents per standard practice. Patients will receive 1-2 cycles of this regimen before proceeding to allo-HSCT.
Drug: Cytarabine ± Anthracycline

Cytarabine (AraC): ≥6g/m² per cycle (e.g., 1-2g/m², every 12 hours on days 1-3), administered intravenously.

May be combined with anthracycline/anthraquinone agents per standard practice. Patients will receive 1-2 cycles of this regimen before proceeding to allo-HSCT.
