Description

Summary

This first-in-human (FIH) dose-escalation and dose-validation/expansion study will assess ziftomenib (KO-539), a menin-MLL(KMT2A) inhibitor, in patients with relapsed or refractory acute myeloid leukemia (AML).

Official Title

A Phase 1/2A First in Human Study of the Menin-MLL(KMT2A) Inhibitor KO-539 in Patients With Relapsed or Refractory Acute Myeloid Leukemia

Details

This Phase 1/2a, first-in-human (FIH), open-label, dose-escalation and dose-validation/expansion study will assess ziftomenib (KO-539), a menin-MLL(KMT2A) inhibitor, in patients with relapsed or refractory acute myeloid leukemia (AML). The dose-escalation part of the study (part 1a) will determine the maximal tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D). The dose-validation/expansion part of the study (part 1b) will determine the safety, tolerability, and minimal biologically effective dose of ziftomenib (KO-539) in dosing cohorts which have demonstrated early biological activity and have been determined to be safe in the dose-escalation part.
