The study covered in this summary was published on as a preprint and has not yet been peer reviewed.

Key Takeaway

Why This Matters

  • Cytarabine plus an anthracycline has been the standard AML induction regimen for decades, but only 60% to 70% of patients achieve complete remission.

  • The study establishes daunorubicin/cytarabine plus venetoclax as a safe and effective option for young adults newly diagnosed with AML.

Study Design

  • Overall, 33 patients with AML underwent induction therapy with daunorubicin (60 mg/m2, days 1–3), cytarabine (100 mg/m2, days 1–7) and venetoclax (100 mg day 4, 200 mg day 5, and 400 mg days 6–11).

  • The median patient age was 40 years.

Key Results

  • The complete remission rate after one cycle of daunorubicin/cytarabine plus venetoclax was 91% overall. Complete remission rates were 100%, 83%, and 75% in European LeukemiaNet (ELN) favorable, intermediate, and poor-risk groups, respectively.

  • At a median follow-up of 6 months, 30 patients were in continuous complete remission.

  • Of the 30 patients who achieved complete remission, 29 (97%) had undetectable measurable residual disease.

  • Patients showed rapid recovery from myelosuppression (median of 21 days).

  • Febrile neutropenia (54%), pneumonia (21%), and sepsis (12%) accounted for most of the grade 3–4 adverse events.


  • The study was small, and follow-up time was too short to assess survival benefit; a larger randomized trial is ongoing.

  • The proportion of ELN favorable-risk patients was slightly higher than in previous trials, which might have skewed the results.


  • The work was funded by the Leading Innovative and Entrepreneur Team Introduction Program of Zhejiang and the National Natural Science Foundation of China.

  • The investigators did not disclose any significant financial relationships.
