GroupInterventionDescription
Part 1: Dose EscalationJNJ-80038114Participants will receive JNJ-80038114. The dose levels will be escalated based on the dose limiting toxicities (DLTs) evaluation by the study evaluation team (SET).
Part 2: Dose ExpansionJNJ-80038114Participants will receive JNJ-80038114 at the recommended Phase 2 dose (RP2D) determined in Part 1.
Primary Outcome Measures
NameTimeMethod
Parts 1 and 2: Number of Participants With Adverse Events (AEs)Up to 2 Years 6 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.

Parts 1 and 2: Number of Participants With AEs by SeverityUp to 2 Years 6 Months

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. Cytokine release syndrome (CRS) and associated neurologic toxicity events will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) guidelines.

Part 1: Number of Participants With Dose-Limiting Toxicity (DLT)Up to 2 Years 6 Months

Number of participants with DLT will be reported. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.

Secondary Outcome Measures
NameTimeMethod
Serum Prostate Specific Antigen (PSA) ConcentrationUp to 2 Years 6 Months

Serum PSA concentration will be determined.

Serum Concentration of JNJ-80038114Up to 2 Years 6 Months

Serum concentration of JNJ-80038114 will be determined.

Systemic Cytokine ConcentrationsUp to 2 Years 6 Months

Cytokine concentrations will be determined for biomarker assessment.

Objective Response Rate (ORR)Up to 2 Years 6 Months

ORR is defined as the percentage of participants who have a partial response (PR) or better according to Prostate Cancer Working Group 3 (PCWG3) response criteria.

PSA Response RateUp to 2 Years 6 Months

PSA response rate is defined as the percentage of participants with a confirmed decline in PSA of 50 percent (%) or more from baseline.

Duration of Response (DOR)Up to 2 Years 6 Months

DOR is defined as the duration from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the PCWG3 response criteria, or death due to any cause, whichever occurs first.

Number of Participants With Antibodies to JNJ-80038114Up to 2 Years 6 Months

Serum samples will be analyzed for the detection of antibodies to JNJ-80038114 using a validated assay method.
