Intermediate-dose HAD Regimen for CEBPA Double-mutated AML

Официальное название

A Multicenter, Randomized, Controlled Clinical Trial of Intermediate-dose HAD Regimen for CEBPA Double-mutated Acute Myeloid Leukemia

Обзор

AML is highly heterogeneous in pathogenesis, and CEBPA double-mutated (CEBPAdm) AML is a common type of leukemia in China. Currently, no targeted therapies for CEBPAdm, and chemotherapy and transplantation are still the treatment options for CEBPA double-mutated AML. At present, the "3+7" treatment induction regimen of cytarabine combined with anthracyclines is still the first-line recommended regimen. In our retrospective study, the intermediate dose HAD regimen produced a 3-year RFS of 84.7% and a 3-year OS of 92.8% in CEBPAdm AML. Therefore, this project intends to confirm the efficacy of intermediate-dose HAD in the treatment of CEBPA double-mutated AML is superior to the conventional treatment regimen through the multi-center RCT study.

Подробное описание

This is a prospective, randomized, controlled clinical trial of patients diagnosed with CEBPA double-mutated AML. Patients who meet the inclusion criteria are randomly assigned to receive the intermediate-dose HAD regimen or the conventional 3+7 induction regimen (IA or DA), respectively. When patients reach complete remission (CR) after the induction therapy, 3 courses of the high-dose cytarabine regimen (3g/m2 q12h, 3 days) are used. Hematopoietic stem cell transplantation is recommended for patients with persistent MRD positive after treatment. When patients do not achieve CR after the induction therapy, reinduction therapy with IAC (IDA 10mg/ m2 for 3 days, cytarabine 100mg/m2 for 7 days, cyclophosphamide 350mg/m2 d2, d5) regimen is used. Patients who still do not achieve CR after reinduction therapy will be removed from the group.
