Brief Summary

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).

Percentage of participants who achieve complete Remission (CR) will be reported. CR is defined as Bone marrow blasts less than (\<) 5 percent (%); Absence of circulating blasts; Absence of extramedullary disease; Absolute neutrophil count (ANC) greater than or equal to (\>=) 1.0\*10\^9/Liter (L) (1,000/microliter \[mcL\]); Platelet count \>= 100 \* 10\^9/L (100,000/mcL).

Percentage of Participants who Achieve Complete Remission with Partial Hematologic Recovery (CRh)Up to 3 Years 3 months

Percentage of participants who achieve complete remission with partial hematologic recovery (CRh) will be reported. CRh is defined as All criteria of CR with both ANC \>0.5 \* 10\^9/L (500/mcL) and platelet count \>50 \* 10\^9/L (50,000/mcL).

Percentage of Participants who Achieved Overall ResponseUp to 3 Years 3 months

Percentage of participants who achieve overall response will be reported. Overall response rate (ORR) is defined as the percentage of participants achieving CR, CRh, or CRi, morphologic leukemia-free state (MLFS) or partial remission (PR).
