Summary

This clinical study evaluates the efficacy and safety of maintenance therapy with BCL-2 inhibitors in elderly patients with acute myeloid leukemia (AML) in first complete remission. This study involves the following content: BCL-2 inhibitors.

* Age between 60 and 85 years.
* Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤ 3 times the upper limit of normal (ULN), serum bilirubin ≤ 1.5 times ULN, serum creatinine ≤ 2.0 times ULN, and serum creatine kinase \< 2.0 times ULN.
* Left ventricular ejection fraction (LVEF) ≥ 50% as determined by echocardiography.
* Eastern Cooperative Oncology Group (ECOG) performance status score of 0-3. Obtaining informed consent from the patient or their legal representative.

Exclusion Criteria:
