Impact of venetoclax trough levels on safety and efficacy in the treatment of acute myeloid leukemia.

ABSTRACT: Venetoclax-azacitidine chemotherapy is a key treatment for older or medically unfit patients with acute myeloid leukemia (AML). As venetoclax is metabolized via cytochrome P450 3 A, dose adjustments are required when combined with antifungal agents. However, data on venetoclax concentrations and their impact on safety and efficacy remain limited. This study analyzed the association between venetoclax trough levels and treatment outcomes in 152 AML patients (median age: 70 years). The median trough level was 1,518 ng/mL (range: 60-11,328 ng/mL), with significant interindividual variability, even after adjusting for antifungal use. High venetoclax trough levels were significantly associated with elevated creatinine and total bilirubin levels. Patients with trough levels below 1857.3 ng/mL ha
