Adult Acute Myeloid Leukemia

This is a multi-center, randomized, double-blinded, placebo controlled trial.

The goal of this clinical trial is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of WBC100 capsules in patients with relapsed or refractory acute myeloid leukemia (R/R AML). The main questions it aims to answer are: * What is the safety and tolerability profile of WBC100 in R/R AML patients? * Can WBC100 effectively induce remission in R/R AML patients? Participants will: * Take WBC100 capsules orally once daily in 28-day treatment cycles; * Undergo regular safety assessments, including adverse event monitoring and laboratory tests; * Provide blood samples for pharmacokinetic (PK) analysis; * Have their remission status and efficacy evaluated according to the ELN2022 criteria.

Background: In combination with hypomethylating drugs, venetoclax has recently changed the therapeutic management of patients with newly diagnosed acute myeloid leukemia (AML) for whom standard induction chemotherapy was not an option. Over and above the clinical benefits of this combination, the data show that more than half the patients did not show remission criteria, even after the first month's exposure to venetoclax. Hypothesis: To compare the mean residual venetoclax plasma concentrations obtained in patients who went into complete composite remission versus those who did not go into remission at the end of the first cycle of venetoclax + azacitidine treatment. Method: According to the French law, this is a multicenter, non-comparative, open-label, single-arm, interventional study with minimal risks and constraints. Selection, information and inclusion will concern adult patients (≥60 years) with a confirmed diagnosis of AML according to ELN 2022 guidelines. Included patients will be treated as standard care with a combination of venetoclax+azacitidine. This research protocol will not modify their usual care.
