Overview

This study is a multicenter, prospective, randomized, controlled clinical trial, observing the efficacy and safety of the CACAG+Venetoclax regimen (Chidamide + Azacitidine + Aclarubicin + Cytarabine + Recombinant Human Granulocyte Colony-Stimulating Factor + Venetoclax) in elderly patients with newly diagnosed Acute Myeloid Leukemia (AML). The control group applies the standard "3+7" regimen. The aim is to improve the remission rate of AML patients, reduce the probability of adverse events, and thereby improve patient prognosis and extend patient survival.
