Gilteritinib Plus VA Followed By Consolidation Chemotherapy in Newly Diagnosed FLT3-ITD+ AML
A Single-Center, Prospective, Single-Arm Phase II Clinical Study of Consolidation With High-Dose Cytarabine Following Deep Molecular Remission Induced by Gilteritinib Plus VA Regimen in Newly Diagnosed Intermediate-Risk Fit AML Patients With FLT3-ITD Mutation
First Affiliated Hospital of Zhejiang University

Conditions
Summary
This clinical trial aims to evaluate whether molecular MRD-guided chemotherapy can effectively treat FLT3-ITD mutated AML and potentially replace allogeneic hematopoietic stem cell transplantation. It primarily seeks to answer: * What is the complete remission rate after initial induction with Gilteritinib, Venetoclax, and Azacitidine? * What are the survival rates and safety of subsequent high-dose cytarabine consolidation after two cycles of this induction therapy? As a single-arm study, outcomes will be compared against historical data from standard treatments (including transplant) to assess if the new strategy is equally or more effective. Participants will: * Undergo three cycles of high-dose cytarabine consolidation after two cycles of induction therapy, contingent upon achieving deep FLT3-ITD molecular remission. * Start Gilteritinib maintenance therapy after consolidation if FLT3-ITD remains detectable, continuing until deep molecular remission is achieved again.
Eligibility
Inclusion Criteria4
- Each subject (or their legal representative) must sign an informed consent form (ICF) before any specific study procedures or tests, indicating that he/she understands the purpose and procedures of the study and is willing to participate.
- Age ≥ 18 years or reaching the legal minimum adult age (whichever is greater) and ≤ 60 years (at screening);
- Newly diagnosed acute myeloid leukemia with FLT3-ITD mutation according to the European LeukemiaNet (ELN) 2022 diagnostic criteria (no VAF requirement), with no low-risk or high-risk genetic features as defined by ELN 2022.
- ECOG performance status ≤ 2. Biochemical indicators must be within the following limits within 21 days before randomization and at baseline: ALT and AST ≤ 3× upper limit of normal (ULN); total bilirubin ≤ 3× ULN; serum creatinine ≤ 2× ULN or CrCl ≥ 40 mL/min. LVEF determined by echocardiography is within the normal range (LVEF \> 50%).
Exclusion Criteria8
- Diagnosed with acute promyelocytic leukemia (APL), BCR-ABL positive acute myeloid leukemia, or AML secondary to previous chemotherapy or radiotherapy.
- History of other malignancies, except for adequately treated non-malignant skin melanoma, cured in situ tumors, or other solid tumors that have been treated and have had no evidence of disease for at least 2 years.
- Assessed as unfit for intensive chemotherapy based on the following criteria: ECOG performance status ≥ 2 at screening; severe cardiac diseases (e.g., congestive heart failure requiring treatment, ejection fraction ≤ 50%, or chronic stable angina); severe pulmonary diseases (e.g., DLCO ≤ 65% or FEV1 ≤ 65%); creatinine clearance \< 45 ml/min (calculated by Cockcroft-Gault equation), liver disease with total bilirubin \> 1.5 times the normal upper limit (ULN); any other comorbidities deemed incompatible with intensive chemotherapy by the attending physician.
- Uncontrolled fungal, bacterial, or viral infections.
- Known active clinically relevant liver disease (e.g., active hepatitis B or C); known history of HIV infection (participants should undergo HIV testing before randomization).
- History of allergy to any excipients in gilteritinib tablets.
- Pregnant or breastfeeding women.
- Other conditions deemed unsuitable for this study by the investigator.
Interventions
Phase I. Induction Therapy (2 cycles): Gilteritinib plus 80 mg, orally (po), once daily (qd), continuously from Day 1 of Cycle 1 until the end of Induction.Venetoclax + Azacitidine (VA Regimen): Azacitidine: 75 mg/m², intravenously (iv) or subcutaneously (sc), once daily on Days 1-7 of each 28-day cycle.Venetoclax: Cycle 1: Dose ramp-up: 100 mg po on Day 1, 200 mg po on Day 2, then 400 mg po once daily from Day 3 to Day 28.Subsequent Cycles: 400 mg po once daily on Days 1-28 of each 28-day cycle. Phase II. Consolidation Therapy (3 cycles): High-Dose Cytarabine (HiDAC): 3.0 g/m², intravenously (iv), over 3 hours, every 12 hours (q12h) on Days 1, 3, and 5 (total of 6 doses per cycle)；Gilteritinib: Dose increased to 120 mg, orally (po), once daily (qd), from day8 to day21. The interval of each cycle is 30 days. Phase III. Maintenance Therapy: Gilteritinib: 120 mg, orally (po), once daily (qd), continuously for up to 3 months.
