Low‐dose decitabine plus venetoclax as post‐transplant maintenance for high‐risk myeloid malignancies

Abstract

AbstractRelapse remains a major cause of treatment failure following allogeneic stem cell transplantation (allo‐SCT) for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). We retrospectively investigated low‐dose decitabine and venetoclax (DEC/VEN) as post‐transplant maintenance in 26 older patients with AML and MDS. The cumulative incidence of day 100 gIII‐IV acute graft versus host disease (GVHD) and 1‐year moderate‐severe chronic GVHD was 5% and 26%, respectively. One patient relapsed 14 m after transplant. The 1‐year non‐relapse mortality and survival were 11% and 84%, respectively. DEC/VEN is a safe and potentially effective strategy to reduce the risk of post‐transplant relapse.
