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).


Eligibility criteria: Inclusion Criteria:

* Diagnosed with AML according to the 2022 WHO diagnostic criteria;
* Age 60-75 years;
* Intermediate to high-risk AML according to the ELN criteria, AML with myelodysplasia-related changes (AML-MRC) or therapy-related AML (t-AML), or core-binding factor AML (CBF-AML) with D816 KIT mutation; or newly diagnosed hypercellular leukemia (WBC ≥ 10×10\^9/L);
* Achieved CR or CR with incomplete hematologic recovery (CRi) after one to two courses of induction chemotherapy;
* Have a matched related, haploidentical, or mismatched unrelated hematopoietic stem cell donor;
* Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2; Creatinine clearance ≥ 60 mL/min (calculated using the Cockcroft-Gault formula);
* Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3× the upper limit of normal (ULN), and total bilirubin ≤ 2× ULN;
* Echocardiography (ECHO) showing left ventricular ejection fraction (LVEF) ≥ 50%; Expected survival \> 8 weeks;
* Voluntarily signed the informed consent form and can understand and comply with the study's requirements.

Exclusion Criteria:

* Currently has clinically active cardiovascular disease, such as uncontrolled arrhythmias, uncontrolled hypertension, congestive heart failure, any class 3 or 4 heart disease according to the New York Heart Association (NYHA) functional classification, or a history of myocardial infarction within 3 months before screening;
* Other severe diseases that may limit the patient's participation in this trial (e.g., severe infection, renal failure);
* Known human immunodeficiency virus (HIV) infection or severe viral hepatitis not controlled by medication;
* Pregnant or breastfeeding women;
* Unable to understand, comply with the study protocol, or unable to sign the informed consent form.
