Experimental: Part 1: Dose Escalation
Participants with metastatic castration-resistant prostate cancer (mCRPC) will receive JNJ-63898081. Ascending dose levels will be sequentially tested.
|
Drug: JNJ-63898081
JNJ-63898081 will be administered. |
Experimental: Part 2: Dose Expansion
Participants with mCRPC or renal cell carcinoma (RCC) will receive JNJ-63898081 at the recommended Phase 2 dose (RP2D) determined in Part 1.
|
Drug: JNJ-63898081
JNJ-63898081 will be administered. |
- Part 1 and Part 2: Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability [ Time Frame: Approximately 3 years ]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.
- Part 1: Number of Participants with Dose-Limiting Toxicity (DLT) [ Time Frame: Approximately 3 years ]Number of participants with DLT will be assessed. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.
- Part 1: Severity of Adverse Events as Assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) [ Time Frame: Approximately 3 years ]Severity of AEs has 5 grades based on CTCAE criteria: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening consequences; Grade 5: Death.
- Part 1 and Part 2: Serum Concentrations of JNJ-63898081 [ Time Frame: Approximately 3 years ]Serum samples will be analyzed to determine concentrations of JNJ-63898081 using a validated method.
- Part 1 and 2: Systemic Cytokine Concentrations [ Time Frame: Approximately 3 years ]A panel of cytokines, including those proinflammatory ones, will be measured.
- Part 1 and 2: Concentration of Markers of T-Cell Activation [ Time Frame: Approximately 3 years ]Markers of T-cell activation/exhaustion as well as immunophenotyping will be assessed.
- Part 1 and 2: Number of Participants with JNJ-63898081 Antibodies [ Time Frame: Approximately 3 years ]Anti-JNJ-63898081 antibodies will be evaluated in serum samples collected from all participants.
- Serum Prostate Specific Antigen (PSA) Concentration [ Time Frame: Approximately 3 years ]Serum prostate specific antigen (PSA) concentration will be assessed.
- Percentage of JNJ-63898081 Receptor Occupancy [ Time Frame: Approximately 3 years ]Percentage of JNJ-63898081 receptor occupancy will be assessed via flow cytometry.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Histology: Part 1: Metastatic castration-resistant prostate cancer (mCRPC) with histologic confirmation of adenocarcinoma. Adenocarcinoma with small-cell or neuroendocrine features is allowed. mCRPC is defined by prostate Cancer Working Group (PCWG )3 criteria. Part 2: mCRPC as defined above or pathologically confirmed metastatic renal cell carcinoma (RCC) as defined by world health organization (WHO) 2016 Classifications
- Measurable or evaluable disease: Part 1: Either measurable or evaluable disease for prostate cancer. Part 2: At least one measurable lesion as per RECIST v1.1.
- Evidence of disease progression on prior therapy that requires a new line of treatment
- Participants with accessible lesions enrolled in selected pharmacokinetic (PK)/pharmacodynamics (PD) cohorts and in Part 2 must agree to undergo the mandatory fresh tumor biopsies, unless collection of the biopsy presents a safety risk
Exclusion Criteria:
- At least 2 weeks between prior anticancer treatment (including radiotherapy) discontinuation and the first dose of study drug, and toxicities have returned to Grade less than or equal to (<=) 1 or baseline
- Prior treatment with prostate-specific membrane antigen (PSMA)-targeted therapy except for PSMA-targeted vaccine is permitted
- Solid organ or bone marrow transplantation
- Seizure or known condition that may predispose to seizure or intracranial masses
- Other active malignancy requiring systemic treatment <=12 months prior to enrollment
