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.
