Study Endpoints
Primary Endpoints
Percentage of Participants who Achieve Complete Remission (CR)
Up to 4 years and 1 month

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 (1,000/microliter \[mcL\]); Platelet count \>= 100 \* 10\^9/L (100,000/mcL).

Overall Survival (OS)
Up to 4 years and 1 month

Overall survival time is defined as the time duration from the date of randomization to death due to any cause.

Number of Participants with Adverse Events (AEs)
Up to 3 Years 3 months

An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.

Number of Participants with Adverse Events (AEs) by Severity
Up to 3 Years 3 months

Number of Participants with AEs by severity will be reported. Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.

Number of Participants with Dose-limiting Toxicity (DLT)
End of Cycle 1 (28 days)

Number of participants with DLT will be reported according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.

Secondary Endpoints

Up to 4 years and 1 month
Duration of CR

ArmTypeDescription
Arm A: Bleximenib and Venetoclax (VEN) + Azacitidine (AZA)EXPERIMENTALParticipants with acute myeloid leukemia (AML) will receive bleximenib in combination with venetoclax (VEN) and azacitidine (AZA) for 28-days treatment cycles and treatment will continue until progression or unacceptable toxicity.
Arm B: Placebo and Venetoclax (VEN) + Azacitidine (AZA)PLACEBO_COMPARATORParticipants with AML will receive placebo in combination with VEN and AZA for 28-days treatment cycles, and treatment will continue until progression or unacceptable toxicity.
Arm A: Relapsed/Refractory SettingEXPERIMENTALParticipants with relapsed/refractory AML harboring NPM1, KMT2A, NUP98, or NUP214 alterations will receive bleximenib in combination with either venetoclax (VEN) (Cohort A1: bleximenib+VEN) or azacitidine (AZA) (Cohort A2: bleximenib +AZA) or VEN+AZA (Cohort A3: bleximenib+VEN+AZA) or VEN + AZA (Cohort A4: bleximenib + VEN + AZA) in adolescent participants aged greater than or equal to (\>=) 12 years and less than (\<) 18 years of age, to select the recommended phase 2 dose (RP2D) of bleximenib in combination with VEN, AZA or VEN+AZA (dose selection). In dose expansion portion of the study, participants will receive bleximenib in combination with AML directed therapies at the RP2D(s).
Arm B: Newly Diagnosed Chemotherapy Ineligible SettingEXPERIMENTALParticipants will receive bleximenib in combination with VEN+AZA as frontline chemo therapy for newly diagnosed AML participants harboring KMT2A, NPM1, NUP98, or NUP214 alterations who are \>=75 years of age or \>=18 years of age to \<75 years of age with comorbidities that preclude the use of intensive induction chemotherapy.
Arm C: Newly Diagnosed Chemotherapy Eligible SettingEXPERIMENTALParticipants will receive combination of bleximenib with cytarabine+daunorubicin or idarubicin chemotherapy as frontline treatment regimen for participants \>= 18 to \<75 years of age with AML harboring NPM1, KMT2A, NUP98, or NUP214 alterations and eligible for intensive chemotherapy.
