The purpose of Part 1 (Dose Escalation) of the study is to assess the safety and tolerability, and to identify the recommended Phase 2 dose\[s\] (RP2D\[s\]) in participants with relapsed or refractory (R/R) acute myeloid leukemia (AML) (that is a type of blood cancer that has come back after treatment/or has stopped responding to treatment) or R/R higher-risk type of myelodysplastic neoplasms (MDS, type of blood cancer). 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.

Number 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)
Participants with dose-limiting toxicity (DLT) will be assessed. 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: 14 days
Serum Concentration of JNJ- 89853413
Serum samples will be analyzed to determine concentrations of JNJ-89853413 using a validated immunoassay method.
Time frame: Approximately 2.5 years
Area Under the Plasma Concentration-time (AUC[t]) Curve of JNJ-89853413
AUC\[t\] is defined as the area under the plasma concentration time curve during a dosing interval at steady-state.
Time frame: Approximately 2.5 years
Maximum Serum Concentration (Cmax) of JNJ-89853413
Cmax is defined as maximum serum concentration of JNJ-89853413.
Time frame: Approximately 2.5 years
Trough Observed Serum Concentration (Ctrough) of JNJ-89853413
Ctrough is the trough observed serum concentration of JNJ-89853413.
Time frame: Approximately 2.5 years
Number of Participants with Presence of anti-drug Antibodies of JNJ-89853413
Participants with anti JNJ-89853413 antibodies will be analyzed by a bridging electrochemiluminescence (ECL) enzyme linked immune assay.
Time frame: Approximately 2.5 years
Complete Response (CR) in Acute Myeloid Leukemia (AML)
CR is achieved when a participant has a best response of CR (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: 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: 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: 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: Approximately 2.5 years
Time to response (TTR)
TTR is defined for responders only, as the time from the first dose of study drug to first qualifying response.
Time frame: 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: Approximately 2.5 years
