  • Condition or Disease:Neoplasms
  • Intervention/Treatment: Drug: JNJ-63898081
  • Phase: Phase 1
Detailed Description


Study Design

  • Estimated Enrollment: 90 participants
  • Allocation: Non-Randomized
  • Intervention Model: Sequential Assignment
  • Masking: None (Open Label) ()
  • Primary Purpose: Treatment
  • Official Title: A Phase 1, First-in-Human, Dose Escalation Study of JNJ-63898081, in Subjects With Advanced Stage Solid Tumors

Arms and interventions
Arm Intervention/treatment
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.
Outcome Measures
  • Primary Outcome Measures: 1. 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.
  • 2. 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.
  • 3. 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.
  • Secondary Outcome Measures: 1. 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.
  • 2. Part 1 and 2: Systemic Cytokine Concentrations [ Time Frame: Approximately 3 years ]
    A panel of cytokines, including those proinflammatory ones, will be measured.
  • 3. 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.
  • 4. Serum Prostate Specific Antigen (PSA) Concentration [ Time Frame: Approximately 3 years ]
    Serum prostate specific antigen (PSA) concentration will be assessed.
  • 5. Objective Response Rate (ORR) [ Time Frame: Approximately 3 years ]
    ORR is defined as the proportion of participants who have a PR or better according to the disease-specific response criteria. Evaluation of prostate treatment response will be performed according to Prostate Cancer Working Group 3 (PCWG3).
  • 6. Duration of Response [ Time Frame: Approximately 3 years ]
    Duration of response (DOR) will be calculated 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 disease-specific response criteria, or death due to any cause, whichever occurs first. Evaluation of prostate treatment response will be performed according to Prostate Cancer Working Group 3 (PCWG3).
Eligibility Criteria
  • 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:

- Less than 2 weeks between prior anticancer treatment (including radiotherapy)
discontinuation and the first dose of study drug, and toxicities have not 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
