Protocol Title: A Prospective, Randomized Controlled Study of Venetoclax Plus 3-Day Decitabine (DEC3-VEN) Versus Venetoclax Plus "2+6" DA Versus "3+7" DA Regimen in Adult Patients with Newly Diagnosed Acute Myeloid Leukemia (AML)
Objective: This is a prospective, open-label, randomized, multicenter, phase II trial designed to compare the efficacy and safety of three induction regimens-Venetoclax plus 3-day Decitabine (DEC3-VEN), Venetoclax plus "2+6" DA, and standard "3+7" DA-in adult patients with newly diagnosed, intensifiable AML.
Study Design: The study employs a prospective, randomized, controlled, multicenter design. A total of 291 eligible patients will be enrolled across approximately 10 centers in China and randomized in a 2:2:1 ratio to the three treatment arms.
Key Eligibility Criteria:
Inclusion: Aged 16-65 with newly diagnosed non-APL AML (excluding favorable CBF-AML), eligible for intensive chemotherapy, ECOG ≤2, and adequate organ function.
Exclusion: Prior AML treatment, secondary AML, active severe infection, significant cardiac comorbidity, or known hypersensitivity to the study drugs.
Interventions:
Induction:
Arm A (VEN+"2+6"DA): Venetoclax (D1-8), Daunorubicin (D2-3), Cytarabine (D2-7).
Arm B (DEC3-VEN): Venetoclax (D1-14), Decitabine (D4-6). FLT3/ITD+ patients add Sorafenib or Gilteritinib (D8-14).
Arm C ("3+7"DA): Daunorubicin (D1-3), Cytarabine (D1-7).
Consolidation (2 cycles):
Arms A/B: Venetoclax + Intermediate-Dose Cytarabine.
Arm C: High-Dose Cytarabine.
Consolidation (Subsequent cycles):
All arms receive multiple cycles of DA or HA regimens.
Maintenance (6-8 cycles):
Arms A/B: Venetoclax + Azacitidine.
Arm C: Azacitidine.
Main Outcome Measures:
Primary Endpoint: Composite Complete Remission Rate (CR + CRi) after induction.
Secondary Endpoints: Overall Survival (OS), CR rate, MRD-negative rate, Relapse-Free Survival (RFS), Event-Free Survival (EFS), and safety.
Keywords: Acute Myeloid Leukemia, Venetoclax, Decitabine, Consolidation Therapy, Maintenance Therapy, Randomized Controlled Trial.
