How venetoclax blood levels relate to treatment response in acute myeloid leukemia

Prospective, Multicenter, Clinical-biological Cohort Study to Assess Pharmacokinetics and Pharmacodynamics (PK-PD) of Venetoclax (VEN) in Patients With Acute Myeloid Leukemia (AML)

Not applicable Interventional Centre Leon Berard · NCT07243483

This project will test how blood levels of venetoclax relate to treatment effects in adults with AML who are starting venetoclax plus azacitidine.

What this trial studies

This is a prospective, multicenter clinical-biological cohort that will follow 100 adult patients with AML over a 12-month inclusion period while they receive standard venetoclax‑azacitidine therapy. The study will collect serial blood samples (up to 21 additional samplings, maximum 12 mL per sampling day) to measure venetoclax pharmacokinetics and link those levels to pharmacodynamic measures and cytologic response. Therapeutic management is not altered by participation and the protocol excludes patients previously treated with venetoclax or azacitidine, those eligible for intensive chemotherapy, and patients with acute promyelocytic leukemia. The design focuses on real-world treatment settings at several French centers to clarify how drug levels and interactions (for example with azole antifungals) affect outcomes and safety.

Who should consider this trial

Good fit: Adults (≥18) with histologically confirmed AML who are about to start first-line venetoclax plus azacitidine, not previously treated with venetoclax or azacitidine, and not eligible for intensive chemotherapy.

Not a fit: Patients with acute promyelocytic leukemia, those eligible for intensive chemotherapy, those previously treated with venetoclax or azacitidine, or those unable/unwilling to undergo the required blood sampling are unlikely to benefit from joining this cohort.

Why it matters

Potential benefit: If successful, the findings could help personalize venetoclax dosing to improve effectiveness and reduce side effects.

How similar studies have performed: Venetoclax combined with hypomethylating agents has shown clinical benefit in AML and known drug‑drug interactions (notably with azole antifungals) exist, but dedicated prospective PK‑PD cohort data are relatively limited.

* Patient previously treaed with venetoclax and/or azacitidine
* Patient participating to another clinical trial with a medicinal product
* Any condition that contraindicates blood sampling procedures required by the protocol
* Any psychological, family, geographical, or social situation that, according to investigator's judgment, could potentially prevent the signing of an informed consent form and/or woulld likely interfere compliance with study procedures.
