Brief Summary

Pilot Study of Reduced Venetoclax Exposure

Detailed Description

A pilot single-arm clinical trial is proposed to assess the primary objective: the tolerability of 14-day Venetoclax cycles in acute myeloid leukemia (AML) patients who have achieved remission and are ineligible for intensive treatment. Participants in the study will transition to a maintenance regimen that reduces the Venetoclax dosage to 14 days per cycle while continuing the hypomethylating agent (HMA) used during induction. Treatment cycles will occur every 28 days. Participants will continue treatment on study until experiencing a grade 4 cytopenic event lasting more than 7 days, an adverse event requiring regimen modification, relapse, or death.

Our primary hypothesis posits that AML patients receiving Venetoclax for 14 days per cycle will exhibit improved treatment tolerability with a reduced rate of grade 4 cytopenia compared to historical data from the VIALE A trial.
