Conditions
Summary
This phase II trial tests how well VA alternating with low-dose CHA works in treating unfit patients with newly diagnosed acute myeloid leukemia (AML). This is a prospective, multi-centers, single arm phase II study aimed to overcome VEN resistance and achieve greater MRD negative rate, providing better control of treatment for unfit AML.

Interventions
1. Induction Phase (4 alternating cycles): Participants will receive 4 cycles of alternating therapy: * VA Cycle: * Venetoclax 400 mg PO daily on Days 1-28 * Azacitidine 75 mg/m² SC daily on Days 1-7 * Low-dose CHA Cycle: * Cladribine 5 mg/m² IV daily on Days 1-3 * Homoharringtonine 1 mg/m² IV daily on Days 1-5 * Cytarabine 20 mg SC every 12 hours on Days 1-10 Alternating sequence: VA → CHA → VA → CHA → VA → CHA → VA → CHA 2. Maintenance Phase (24 months): Following induction, participants will receive: * Venetoclax 400 mg PO daily on Days 1-28 * Azacitidine 75 mg/m² SC daily on Days 1-7 Repeated every 28 days for 24 cycles. We aimed to compare this clinical intervention with standard VA which is: * Venetoclax 400 mg PO daily on Days 1-28 * Azacitidine 75 mg/m² SC daily on Days 1-7 Repeated every 28 days for at least 24 cycles.
