Study on the Efficacy and Safety of VA Regimen Compared to "3+7" Regimen in Newly Diagnosed AML With NPM1 or IDH1/IDH2 Mutations

Официальное название

A Prospective, Multicenter, Randomized Controlled, Open Label, Non-Inferiority Study Comparing the Efficacy and Safety of the VA Regimen (Venetoclax Combined With Azacitidine) With the "3+7" Regimen in the Treatment of Newly Diagnosed AML Patients With NPM1 or IDH1/IDH2 Mutations

Обзор

This prospective, multicenter, randomized, open-label, non-inferiority clinical study aims to compare the efficacy and safety of VA regimen (venetoclax combined with azacitidine) versus conventional "3+7" chemotherapy regimen in adult patients aged 18 to 65 years with newly diagnosed acute myeloid leukemia (AML) carrying NPM1, IDH1 or IDH2 gene mutations. The primary goal of this trial is to check whether the VA treatment can reach a non-inferior composite complete remission rate at the end of the induction treatment cycle, which is the key primary endpoint of this research. Several secondary clinical outcomes will also be evaluated in this study, including the rate of minimal residual disease (MRD) negativity after remission, duration of remission, 1-year event-free survival rate and 1-year overall survival rate of enrolled patients. In addition, the safety and treatment-related side effects occurring during the whole induction treatment phase will be systematically collected and compared between two groups as another important secondary assessment. Eligible enrolled participants will be randomly split into two study groups: patients in experimental group will receive venetoclax plus azacitidine (VA regimen), while patients in control group will receive standard "3+7" induction chemotherapy following conventional clinical protocol. All subjects will complete regular disease assessment, laboratory examinations and scheduled follow-up visits as required by trial design during treatment and post-treatment observation period. Researchers will collect and analyze all above clinical outcome data from all participants, to verify the non-inferior efficacy and relative safety of VA regimen for this specific subtype of newly diagnosed AML patients.
