Mitoxantrone Hydrochloride Liposome in Combination With Cytarabine and Venetoclax Regimen in Newly Diagnosed Elderly AML

Summary

This is a phase 2 study to evaluate the efficacy and safety of mitoxantrone hydrochloride liposome in combination with cytarabine and venetoclax (MAV) regimen in newly diagnosed elderly AML. To account, conservatively, for a 10% dropout rate before study completion, we planned to include 42 patients. The primary endpoint is 2-year event free survival(EFS).

2. Aged 60-70 years (including boundary values 60 and 70);
3. Newly diagnosed primary AML according to the WHO 2022 classification.
4. Physical status score of Eastern Oncology Collaboration Group (ECOG) : 0-2.
5. Life expectancy ≥ 3 months.
6. ALT/AST≤2.5 ULN (for subjects with hepatic infiltration≤5 ULN); Total bilirubin≤1.5 ULN (for subjects with hepatic infiltration≤3 ULN); Serum creatinine≤1.5 ULN.

Exclusion Criteria:

1. Subjects meet any of the following conditions:

   5. Cardiac ejection fraction (EF) was less than 50%;
   6. A history of myocardial infarction, unstable angina pectoris, severely unstable ventricular arrhythmia or any other arrhythmia requiring treatment, a history of clinically severe pericardial disease, or electrocardiogram evidence of acute ischemic or active conduction abnormalities within 6 months prior to enrollment;
7. Uncontrolled systemic diseases (such as advanced infections, uncontrolled hypertension, diabetes, etc.);
8. Human immunodeficiency virus (HIV) infection (HIV antibody positive);
9. HBsAg or HBcAb positive, with HBV-DNA≥1x10\^3 copies/mL; HCV Ab positive, with HCV-RNA≥1x10\^3 copies/mL;
