The purpose of Part 1 (Dose Escalation) of the study is to assess the effective dose (recommended Phase 2 dose\[s\] \[RP2Ds\]) that can be safely administered, and dosing regimens of JNJ-90189892 in participants with relapsed or refractory (R/R) acute myeloid leukemia (AML) or R/R higher-risk type of myelodysplastic neoplasms (MDS \[type of cancer of the blood and bone marrow, which does not respond to treatment or comes back after treatment\]). The purpose of Part 2 (Cohort Expansion) is to further assess the safety, tolerability and efficacy in participants with R/R AML or higher-risk types of MDS at the RP2D regimen(s). The purpose of Part 3 and 4 is to assess the effective dose (recommended Phase 2 combination dose \[RP2CD\]) that can be safely administered, and dosing regimens of JNJ-90189892 in combination with azacitadine (AZA) + venetoclax (VEN) in participants with R/R AML (part 3) and newly diagnosed (ND) AML (part 4).

RECRUITINGNumber of Participants with Adverse events (AEs) by Severity
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.
Time frame: From screening untill 30 days after last dose of study drug (that is approximately 2.5 years)
Part 1: Number of Participants with Dose-Limiting Toxicity (DLTs)
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.
Time frame: At least 14 days
Serum Concentration of JNJ-90189892
Serum samples will be analyzed to determine concentrations of JNJ-90189892.
Time frame: Up to approximately 2.5 years
Area Under the Curve Over a Dosing Interval (AUC tau) of JNJ-90189892
AUC tau is the total observed plasma concentration of JNJ-90189892 in the body during the time between doses. AUCtau of JNJ-90189892 will be reported.
Time frame: Up to approximately 2.5 years
Maximum Observed Plasma Concentration (Cmax) of JNJ-90189892
Cmax is the maximum observed plasma concentration of JNJ-90189892. Cmax of JNJ-90189892 will be reported.
Time frame: Up to approximately 2.5 years
Minimum Observed Plasma Concentration (Cmin) of JNJ-90189892
Cmin is the minimum observed plasma concentration of JNJ-90189892. Cmin of JNJ-90189892 will be reported.
Time frame: Up to approximately 2.5 years
Number of Participants with Presence of Anti-JNJ-90189892 Antibodies
Participants with presence of anti-JNJ-90189892 antibodies will be reported.
Time frame: Up to approximately 2.5 years
Complete Response (CR) in Acute Myeloid Leukemia (AML)
CR is achieved when a participant has a best response of CR (including complete response with partial hematologic recovery \[CRh\] or complete response with incomplete hematologic recovery \[CRi\]) according to the European Leukemia Network (ENL) 2022 criteria.
Time frame: Up to approximately 2.5 years
Overall Response (OR) in Myelodysplastic Neoplasms (MDS)
OR is achieved when a participant with MDS has a CR (any type, that is CRh or complete response with limited count recovery \[CRL\]), partial response (PR), or hematologic improvement (HI) according to the International Working Group (IWG) 2023 criteria.
Time frame: Up to approximately 2.5 years
Complete Response in MDS
CR is achieved when a participant has a best response of CR (including CRh/CRL) according to the IWG 2023 criteria.
Time frame: Up to approximately 2.5 years
Duration of Response (DOR)
DOR is defined for responsders only, as time from date of initial documentation of a response to the first documented evidence of no reponse, disease progression, relapse, initation of a new systemic anti-cancer therapy (besides hematopoietic stem cell transplant \[HSCT\]), or death, whichever comes first.
Time frame: Up to approximately 2.5 years
Time to Response (TTR)
TTR is defined for responders, as the time from the first dose of study drug to first qualifying response.
Time frame: Up to approximately 2.5 years
Number of Participants Achieving Transfusion Independence
Transfusion independence is defined as the absence of red blood cell (RBC) and platelet transfusions for 8 weeks or longer after starting study treatment for participants with AML and 16 weeks or longer for participants with MDS.
Time frame: Up to approximately 2.5 years
Part 4 Only: Overall Survival (OS)
OS is defined as the time from the date of first dose of study treatment to the date of death due to any cause.
Time frame: Up to approximately 2.5 years
Part 4 Only: Event-Free Survival (EFS)
EFS is defined as the time from the date of first dose of study treatment to the date of first documented evidence of treatment failure, relapse or death due to any cause, whichever occurs first.
Time frame: Up to approximately 2.5 years
