Study Endpoints
Primary Endpoints
Number of Participants with Adverse events (AEs) by Severity
From screening untill 30 days after last dose of study drug (that is approximately 2.5 years)

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. 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, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.

Part 1: Number of Participants with Dose-Limiting Toxicity (DLTs)
At least 14 days

DLT is defined as any toxicity that requires discontinuation of treatment, any Grade 5 toxicity; Non-hematologic toxicity (Grade 3 or 4) and Hematologic toxicity.

Secondary Endpoints
Serum Concentration of JNJ-90189892
Up to approximately 2.5 years
Area Under the Curve Over a Dosing Interval (AUC tau) of JNJ-90189892
Up to approximately 2.5 years
Maximum Observed Plasma Concentration (Cmax) of JNJ-90189892

JNJ-90189892: MonotherapyEXPERIMENTALParticipants will receive JNJ-90189892 in Part 1 (Dose escalation) of the study and the dose levels will be escalated sequentially based on the decisions of the study evaluation team (SET) until the recommended phase 2 dose (RP2D) has been identified. Participants in Part 2 (Dose expansion) will receive JNJ-90189892 at the RP2D determined in Part 1.
JNJ-90189892: In Combination with Azacitadine (AZA)+ Venetoclax (VEN)EXPERIMENTALParticipants with relapsed or refractory (R/R) acute myeloid leukemia (AML) in Part 3 will receive JNJ-90189892+ AZA+VEN to determine the recommended Phase 2 combination dose (RP2CD). The starting JNJ-90189892 dose regimen in Part 3 will be at least 1 dose level below the highest dose level cleared in Part 1 as determined by the SET. In Part 4 participants with newly diagnosed (ND) AML will receive JNJ-90189892+ AZA+VEN starting from the JNJ-90189892 dose level determined safe in Part 3 by the SET.
