This first-in-human (FIH) dose-escalation and dose-validation/expansion study will assess ziftomenib, a menin-MLL(KMT2A) inhibitor, in patients with relapsed or refractory acute myeloid leukemia (AML) as part of Phase 1. In Phase 2, assessment of ziftomenib will continue in patients with NPM1-m AML.
