Brief summary
This study is to assess the efficacy and safety of Lisaftoclax for prevention of DS in APL patients undergoing ATRA/ATO induction regimen.
Interventions
After the diagnosis of acute promyelocytic leukemia (APL), patients receive initial treatment with all-trans retinoic acid (ATRA) 25 mg/m²/day and arsenic trioxide (ATO) 0.16 mg/kg/day. During the induction phase, lisaftoclax (APG-2575) is administered orally once daily with a dose-escalation schedule for differentiation syndrome prophylaxis: Day 1: 20 mg; Day 2: 50 mg; Day 3: 100 mg; Day 4: 200 mg; Day 5: 400 mg; starting on Day 6: 600 mg once daily, maintained through Day 28. Patients with suspected differentiation syndrome receive dexamethasone or ruxolitinib as per the study protocol.
