Lancet Haematol: Jin Jie / Zhu Honghu team used Veneclax + DA regimen to treat AML, the first CR was as high as 91%

Acute myelogenous leukemia (AML) is the most common acute leukemia in adults (accounting for more than 80%), and its treatment is still dominated by chemotherapy, DA regimen consisting of daunorubicin and cytarabine ( Also known as the "3+7" regimen) is the standard induction regimen for adult AML, and the one-course remission rate of this regimen is about 60%-65% in young AML patients (<60 years old) and 60%-65% in older AML patients (≥60 years old).

The HAA program designed by the team of Professor Jin Jie from the Department of Hematology of the First Affiliated Hospital of Zhejiang University in early 2000 (in domestic multi-center clinical studies, the remission rate was increased by 12 percentage points compared with the international standard program, reaching a CR rate of 73% (Lancet Oncology 2013)

This is an investigator-initiated, multicenter, two-phase, phase 2 clinical trial

The primary endpoint is composite response rate after the first cycle (CRc: CR+CRi), and secondary endpoints include minimal residual disease (MRD), event-free survival (EFS), and overall survival (OS) detected by flow cytometry and adverse events

From December 25, 2020, to July 7, 2021, a total of 36 adult patients with new-onset AML in three hospitals were recruited, and 33 patients were finally evaluated

Outcomes of patients with different molecular subtypes were further analyzed

At a median follow-up of 11 months (IQR 9-12) , 4 of the 30 patients in remission relapsed (2 after completing all required treatment regimens and 2 after allo-HSCT)

The safety analysis showed that adverse events (AEs) during the first cycle of induction therapy with DAV are shown in Table 3

This study shows that a new DAV regimen consisting of veneclax added to the standard DA regimen can achieve a CR rate of up to 91% after one course of induction therapy

At the same time, the encouraging results of this phase 2 study will be further validated by the same group's ongoing randomized controlled trial comparing DAV and DA regimens in newly diagnosed adult AML patients (ChiCTR2100045780)
