A Phase 1b Study of Bleximenib in Combination With AML-Directed Therapies for Participants With Acute Myeloid Leukemia Harboring KMT2A or NPM1 Alterations

Description

The purpose of this study is to determine the recommended Phase 2 dose (RP2D) candidate(s) of bleximenib in combination with AML directed therapies (dose selection) and further to evaluate safety and tolerability of bleximenib in combination with AML directed therapies at the RP2D(s) (dose expansion).
