Brief Summary

Elderly patients with acute myeloid leukemia (AML) often face unfavorable prognostic factors such as multiple comorbidities, adverse cytogenetic profiles, and pre-existing hematological disorders. The long-term survival rate remains very low, with a 5-year survival rate of only 5% to 10%. The introduction of the BCL-2 inhibitor venetoclax (Ven) has improved the induction remission rates in elderly patients. However, the question of whether to use chemotherapy maintenance or proceed with allogeneic hematopoietic stem cell transplantation (allo-HSCT) for post-remission consolidation therapy remains unclear due to the lack of prospective controlled studies. Therefore, our center plans to conduct a prospective, open-label, two-arm, non-randomized, single-center study to further explore the optimal consolidation treatment strategy for elderly AML patients at intermediate and high risk following induction complete remission (CR).

Interventions

Venetoclax DRUG

The consolidation therapy involves a regimen of intermediate-dose cytarabine (Ara-C) combined with Ven, specifically Ara-C at 1.0 g/m²/day for 3 days (days 1-3) and Ven at 400 mg/day for 10 to 14 days (days 1-10 to 14), with each cycle lasting 4 to 6 weeks, for a total of 3 consolidation cycles. This is followed by maintenance therapy with azacitidine (AZA) at 50 mg/m²/day for 5 days (days 1-5), with each cycle lasting 4 weeks, for a total of 6 maintenance cycles.

VAA group

Allogeneic transplant DRUG

The consolidation therapy involves allo-HSCT, with the choice of conditioning regimens typically using reduced-intensity conditioning such as the Fludarabine+Busulfan (FluBu) or Fludarabine+Melphalan (FluMel) regimens commonly used by centers, which can also include Ven. FluBu regimen: Flu 30 mg/m²/day from day -10 to day -5, Bu 3.2 mg/kg/day from day -6 to day -5 or day -7 to day -5, antithymocyte globulin (ATG) (e.g., rabbit ATG at a total dose of 6-7.5 mg/kg, administered from day -4 to day -1), and Ven from day -10 to day -4. FluMel regimen: Flu 30 mg/m²/day from day -10 to day -5, Mel 50-70 mg/m²/day from day -4 to day -3, ATG and Ven from day -10 to day -4. 12 weeks (±4 weeks) post-HSCT maintenance begins with AZA at 32 mg/m²/day for 5 days (days 1-5), with each lasting 6 weeks, for a total of 6 cycles. Donor lymphocyte infusion is allowed in cases of minimal residual disease (MRD) positivity.
