Allogeneic Hematopoietic Cell Transplantation for Acute Myeloid Leukemia in First Complete Remission after 5-Azacitidine and Venetoclax: A Multicenter Retrospective Study

The therapeutic landscape for acute myeloid leukemia (AML) has evolved in recent years with the introduction of hypomethylating agents (HMA) and venetoclax in patients previously deemed unfit for curative - intent treatment. Some of these patients undergo allogeneic hematopoietic cell transplant (alloHCT), yet there are scarce data regarding transplantation outcomes. We conducted a multicenter nationwide retrospective cohort study to evaluate outcomes of patients with AML who underwent alloHCT in first CR (CR1) after frontline treatment with 5-azacitidine plus venetoclax (aza-ven group). In addition, we collected a historical control group of patients who achieved CR1 following first line intensive chemotherapy followed by alloHCT (intensive group). 24 patients in the aza-ven group were transplanted between 2019 and 2021. Compared to the intensive group, patients in the aza-ven group were older (median age 71.7 vs. 58.4 years, p
