Summary

This is a multi-center, prospective, single-arm, phase 2 clinical study conducted in China to evaluate the efficacy and safety of Lisafotoclax combined with Decitabine and Homoharringtonine in patients with acute myeloid leukemia (AML) who have failed or are intolerant to prior treatment with Venetoclax plus Azacitidine. Eligible participants must be at least 18 years old, have a confirmed diagnosis of AML according to WHO 2016 criteria, and have an ECOG performance status of 0-2. Participants will receive oral Lisafotoclax in combination with intravenous Decitabine and Homoharringtonine according to the study protocol. The primary objective is to assess the overall response rate (ORR) after induction treatment. Secondary objectives include evaluating complete remission (CR) rate, event-free survival (EFS), overall survival (OS), and the incidence of adverse events (AEs) and serious adverse events (SAEs). Participants will be followed for up to 12 months after the last patient is enrolled to collect long-term efficacy and safety data. This study has been approved by the Ethics Committee of the Second Affiliated Hospital of Zhejiang University School of Medicine and will be conducted in accordance with the principles of the Declaration of Helsinki and Good Clinical Practice (GCP).

Conditions

• Acute Myeloid Leukemia (AML)

Interventions

Type	Name	Description
DRUG	Lisafotoclax	Oral investigational BCL-2 inhibitor, administered in two phases: 1. LDH induction/consolidation phase (28-day cycles): * Cycle 1: 200 mg on day 1, 400 mg on day 2, 600 mg on days 3-28; * Cycle 2 and beyond: 600 mg once daily on days 1-28. 2. LD maintenance phase (28-day cycles): 600 mg once daily on days 1-14.
DRUG	Decitabine	Intravenous hypomethylating agent, administered at 15 mg/m²/day via intravenous infusion over 3 hours on days 1-3 of each 28-day cycle, used in both LDH induction/consolidation and LD maintenance regimens.
DRUG	Homoharringtonine	Intraversible alkaloid anti-leukemia agent, administered at 1 mg/m²/day via intravenous infusion over 2 hours on days 1-7 of each 28-day cycle, used exclusively in the LDH induction/consolidation phase of the study.
