简要总结
This is a multicenter, randomized, controlled, open-label phase III trial evaluating the efficacy and safety of the VAG regimen (azacitidine, venetoclax, and gilteritinib) compared with standard 3+7 chemotherapy (cytarabine plus daunorubicin or idarubicin) combined with gilteritinib in newly diagnosed, fit patients with FLT3-mutated acute myeloid leukemia (AML). A total of 300 patients aged ≥14 to <75 years with FLT3-ITD or FLT3-TKD mutations will be enrolled and randomized 1:1 to the experimental or control arm, stratified by age (≤60 vs. >60 years). The primary endpoint is event-free survival (EFS). Secondary endpoints include composite complete remission (CRc) rate, minimal residual disease (MRD) negativity rate by flow cytometry and NGS, overall survival (OS), relapse-free survival (RFS), and 30-day and 60-day mortality.
详细描述
This study is designed to investigate whether the triplet combination of azacitidine (a hypomethylating agent), venetoclax (a BCL-2 inhibitor), and gilteritinib (a FLT3 inhibitor) as induction therapy improves outcomes compared to standard intensive chemotherapy plus gilteritinib in patients with newly diagnosed FLT3-mutated AML who are fit for intensive chemotherapy.
