A Prospective, Multicenter, Single Arm Clinical Study to Evaluate Efficacy of HAD Induction With Intensified Cytarabine in Newly-diagnosed CEBPA Double Mutated Acute Myeloid Leukemia
Acute myeloid leukemia is a heterogenous hematological malignancy, characterized by different cytogenetic or molecular features. CEBPA double mutation acute myeloid leukemia （CEBPAdm AML）has favourite prognosis, especially in younger adult patients. But cumulative incidence of relapse of this group patients is still high, so the treatment options need to be optimized urgently.HAD(homoharringtonine(HHT)+cytarabine+daunorubicin) with intermediate dose cytarabine improved the survival of AML, especially in patients with CEBPA double mutation.
In this phase 2 study, 40 patients will be enrolled and treated with HAD induction regimen. High dose cytarabine will be given after complete remission achieved. The primary endpoint was event-free and relapse-free survival. Genetic mutations and measurable residual disease (MRD) will be detected at diagnosis and after chemotherapy. The risk stratification according to genetic mutations and MRD will also be explored.
induction chemotherapy:HHT 2mg/m2/d,day 1-7 cytarabine 100mg/m2/d, day1-4；1g/m2 /q12h ，day5-7 DNR 40mg/m2/d，day 1-3 re-induction chemotherapy:IDA 10mg/m2，day 1-3 cytarabine 100mg/m2，day 1-7 CTX 350mg/m2，day 2，day 5 consolidation chemotherapy: high dose cytarabine 3g/m2/Q12h,day1-3,for three cycles
