In the biomarker evaluable population, FLT3 mutation was detected in 42 (15%) and 22 (19%) patients in the venetoclax+azacitidine and azacitidine groups. Composite complete remission (CRc, complete remission [CR]+CR with incomplete hematologic recovery [CRi]) rates (venetoclax+azacitidine /azacitidine) for FLT3 mutant patients were 67%/36%, median duration of remission (DoR) was 17.3/5.0 months, and median OS was 12.5/8.6 months. The CRc rates among FLT3 wild-type were 67%/25%, median DoR 18.4/13.4 months, and median OS 14.7/10.1 months. When treated with venetoclax+azacitidine, patients with FLT3 mutations and FLT3 wild-type had similar outcomes.
