Stopping venetoclax plus azacitidine after about 12 months in AML responders
Official title: De-Escalation Study Evaluating Venetoclax and Azacitidine Discontinuation in AML Responding Patients
Run by Institut Paoli-Calmettes · NCT06557421 · Data updated 2026-11-12
This trial will test whether stopping venetoclax plus azacitidine after about 12 months keeps adults with AML who are in remission and MRD-negative disease-free and safe.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with previously untreated AML who received first-line venetoclax plus azacitidine for about 12 months, achieved CR/CRi/CRh, are locally MRD-negative, and have ECOG performance status <3.
✕Probably not a fit
Patients who remain MRD-positive, are not in first composite remission, received prior non–venetoclax/azacitidine therapies, or cannot commit to close follow-up are unlikely to benefit from this de-escalation strategy.

What this trial studies
This phase 2 interventional study enrolls adults with previously untreated AML who received first-line venetoclax plus azacitidine for roughly 12 months and achieved a first composite complete remission with no detectable MRD. Enrolled patients will discontinue venetoclax–azacitidine and undergo close, regular monitoring for disease recurrence, with the primary endpoint focused on disease-free survival after treatment stop. Results from the prospective cohort will be compared to a retrospectively selected cohort with identical eligibility to contextualize outcomes, and additional efficacy and safety measures will be recorded. The study aims to determine whether therapy de-escalation can reduce treatment burden without compromising leukemia control.
Why it matters
Potential benefit: If successful, this approach could allow some patients to stop long-term venetoclax–azacitidine, reducing side effects and treatment burden while maintaining remission.
How similar studies have gone: Small retrospective reports and subgroup analyses have suggested stopping therapy in select MRD-negative AML patients may be feasible, but prospective evidence is still limited.

Diagnosis of previously untreated AML according to the 2022 International Consensus Classification of Myeloid Neoplasms and Acute Leukemias; 3. VEN-AZA given as first-line treatment; 4. Duration of VEN-AZA therapy of 12 months (+/- 28 days), regardless of duration of VEN-AZA cycles and the doses; 5. Patients in first composite complete remission (CRc) defined as complete remission (CR) or CR with incomplete hematologic recovery (CRi) or CR with partial hematologic recovery (CRh); 6. Absence of detectable minimal residual disease (MRD) performed locally (i.e. MRDneg defined as MCF MRD \<0.1% of CD45 expressing cells with the target immunophenotype in bone marrow, or NPM1 or RUNX1-RUNX1T1 or CBFB-MYH11 MRD copy numbers \<0.1% in the blood); 7. ECOG \<3; 8. Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; 9.

Prior allogeneic stem cell transplant; 3. Discontinuation of treatment because of absence or loss of response; 4. Patient in emergency situation or unable to give consent; 5. Severe medical or mental condition precluding the follow up procedures after treatment discontinuation.
