A Multicenter Trial Evaluating Efficacy and Safety of A Reduced Venetoclax Exposure To Seven Days Versus Standard Continuous Venetoclax Exposure Combined With Azacitidine in Treatment Naïve Subjects With Acute Myeloid Leukemia Who Are Ineligible for Intensive Induction

Summary

Combination of azacitidine (AZA) for 7 days every 28 days with a continuous daily exposure to Venetoclax (VEN), an oral bcl-2 inhibitor, is now approved for the treatment of acute myeloid leukemia (AML) in patients ineligible for intensive chemotherapy due to age (\>75 years) or comorbidities. VEN+AZA showed significant overall response rate and survival benefit but combination carries a risk of considerable toxicity (such as profound/prolonged cytopenia and infections) before but also after remission. These toxicities make it difficult to apply the recommended treatment regimen, in particular the continuous daily intake of VEN. Recent reports suggest that reducing VEN duration per cycle seems safe and feasible. We propose to investigate a reduced-intensity VEN regimen (7-day dosing/28) versus the standard continuous VEN therapy (28-day dosing/28), combined with AZA, with the primary goal of maintaining efficacy while reducing associated toxicity.
