Sellas Life Sciences Group Inc. announced that data from its ongoing Phase 2 study of SLS009 will be presented at the 67th American Society of Hematology $(ASH)$ Annual Meeting and Exposition, scheduled for December 6-9, 2025, in Orlando, Florida. The trial is evaluating SLS009, a highly selective CDK9 inhibitor, in combination with azacitidine and venetoclax for the treatment of relapsed or refractory acute myeloid leukemia with myelodysplastic syndrome-related changes following prior venetoclax-based treatment. An abstract describing the proposed mechanism of action of SLS009, including its cytotoxic effects in AML cell lines with leukemia-driving mutations, has been published on the ASH Annual Meeting website and will also be available in Blood. The results of the Phase 2 study are to be presented on December 7, 2025.
