Alexandre Bazinet, MD, McGill University, Montreal, Canada, presents findings from a Phase I/II study (NCT04160052) of venetoclax and 5-azacytidine, a hypomethylating agent (HMA), in patients with relapsed/refractory myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML). HMA monotherapy currently represents the standard of care in these groups of patients but durability of response rates remain low. Patients who are treatment naïve or progressed on HMAs were recruited, with the primary outcomes being safety, tolerability, and overall response rate (ORR). Whilst the regimen was generally well tolerated and there were high response rates across the cohort, cases of myelosuppression hindered recovery. This interview took place at the 63rd ASH Annual Meeting and Exposition congress in Atlanta, GA.
