Advanced Prostate Cancer
Conditions
Brief summary
The purpose of the study is to determine the recommended regimen for Phase 2 (RP2Rs) of combination of JNJ-87189401 with JNJ-78278343 (Part 1: dose escalation) and further evaluate the safety at RP2Rs (Part 2: dose expansion) in participants with advanced prostate cancer.

Inclusion criteria
* Histologically confirmed adenocarcinoma of the prostate. Adenocarcinoma with small cell or neuroendocrine (NE) features is permitted. However, small cell carcinoma, carcinoid tumor, mixed NE carcinoma, or large cell NE carcinoma is disallowed * Measurable or evaluable disease per PCWG3 criteria * Part 1, Part 2A and Part 2B: Prior orchiectomy or medical castration; participants who have not undergone orchiectomy, must be receiving ongoing androgen deprivation therapy with a gonadotropin releasing hormone (GnRH) analog (agonist or antagonist), prior to the first dose of study drug and must continue this therapy throughout the treatment phase * Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Exclusion criteria
* Active autoimmune disease within the 12 months prior to signing consent that requires systemic immunosuppressive medications (example, chronic corticosteroids, methotrexate, or tacrolimus) * Any of the following within 6 months prior to signature of informed consent: a. myocardial infarction, b. severe or unstable angina, c. clinically significant ventricular arrhythmias, d. congestive heart failure (New York Heart Association \[NYHA\] class II to IV), e. transient ischemic attack, and f. Cerebrovascular accident
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Part 1: Number of Participants With Dose Limiting Toxicity (DLT) | Up to 21 days after first combination dose of study drugs | DLTs are specific adverse events (AEs) and are defined as any of the following: high grade non-hematologic toxicity or hematologic toxicity. |
| Part 1 and Part 2: Number of Participants with Adverse Events (AEs) by Severity | Up to 3 years 7 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. Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 with the exception of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome events, which will be graded by American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Part 2: Serum Concentration of JNJ-87189401 | Up to 3 years 7 months | Serum samples will be analyzed to determine concentrations of JNJ-87189401. |
| Number of Participants With Antibodies to JNJ-87189401 and JNJ-78278343 | Up to 3 years 7 months | Number of participants with antibodies to JNJ-87189401 and JNJ-78278343 will be reported. |
| Objective Response Rate (ORR) | Up to 3 years 7 months | ORR is defined as the proportion of participants who have a partial response (PR) or better according to response evaluation criteria in solid tumors (RECIST) version 1.1 without evidence of bone progression according to Prostate Cancer Working Group 3 (PCWG3). |
| Radiographic Progression-Free Survival (rPFS) | Up to 3 years 7 months | rPFS is defined time from the date of first dose of study drug until the date of objective disease progression or death, whichever comes first. |
| Prostate Specific Antigen (PSA) Response Rate | Up to 3 years 7 months | PSA response rate is defined as the percentage of participants with a confirmed decline of PSA of 50 percent (%) or more from baseline. |
| Duration of Response (DOR) | Up to 3 years 7 months | DOR is defined for participants who achieved response (PR or better) as the time between the date of initial documentation of response (PR or better) to the date of first documented evidence of progressive disease, as defined in the PCWG3, or death due to any cause, whichever occurs first. |
