Clinical Trial Summary

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.

Description:

This Phase 1/2, first-in-human (FIH), open-label, 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).

The dose-escalation part of the study (Phase 1a) will determine the maximal tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D).

The dose-validation/expansion part of the study (Phase 1b) will determine the safety, tolerability, and minimal biologically effective dose of ziftomenib in dosing cohorts which have demonstrated early biological activity and have been determined to be safe in the dose-escalation phase.

The Phase 2 portion of the study will determine the safety, tolerability, and anti-leukemia activity of ziftomenib in patients with NPM1-m AML.
