Study of VA Combined With HAAG Regimen in Newly Diagnosed Intermediate and High-risk AML Patients

A Single-center, Single-arm, Prospective Clinical Study on the Efficacy and Safety of Venetoclax and Azacitidine Combined With HAAG in the Induction Treatment of Intermediate and High-risk Acute Myeloid Leukemia

The purpose of this study is to evaluate the efficacy and safety of VA combined with HAAG in the induction treatment of newly diagnosed acute myeloid leukemia.

This is a single-center, single-arm, prospective clinical study in newly diagnosed intermediate and high-risk AML patients. The patients will receive venetoclax, azacitidine combined with HAAG regimen in the induction treatment.

3. ECOG score: 0-2.
4. No history of previous chemotherapy or target therapy.
5. Serum total bilirubin <= 2 times the upper limit of normal (ULN), alanine aminotransferase (ALT) <= 1.5 times ULN, aspartate aminotransferase (AST) <=1.5 times ULN;
6. Creatinine clearance rate >=30 mL/min;
7. Serum lipase <= 1.5 times ULN, amylase <= 1.5 times ULN;
8. Capable to understand and willing to participate in this study, signed the informed consent form.

Exclusion Criteria:

1. AML transformed with chronic myelogenous leukemia.
2. Acute promyelocytic leukemia (type M3).
3. Patients with a second malignancy requiring treatment.
4. Patients with uncontrolled active infection.
