Arms and Interventions

Arm Intervention/Treatment
Experimental: JNJ-78278343 + Cetrelimab: Part 1 (Dose Escalation) and Part 2 (Dose Expansion)

Participants will receive subcutaneous (SC) administration of JNJ-78278343 in combination with intravenous (IV) infusion of cetrelimab during Part 1 (dose escalation). The dose of JNJ-78278343 will be escalated sequentially until a recommended phase 2 dose (RP2D). Participants will receive the combination treatment at the RP2D in Part 2 (dose expansion)

Drug: JNJ-78278343
JNJ-78278343 will be administered subcutaneously.

Drug: Cetrelimab
Cetrelimab will be administered by intravenous infusion.

  • Outcome Measures

    Primary Outcome Measures

    1. Part 1: Number of Participants With Dose Limiting Toxicity (DLT) [Up to 21 days after first dose of cetrelimab]

      DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity or hematologic toxicity.

    2. Part 1 and Part 2: Number of Participants with Adverse Events (AEs) by Severity [Up to 2 years 10 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 Outcome Measures

    1. Overall Response Rate (ORR) [Up to 2 years 10 months]

      ORR is defined as the percentage of participants who have a partial response (PR) or better without evidence of bone progression according to Prostate Cancer Working Group 3 (PCWG3) criteria.

    2. Prostate Specific Antigen (PSA) Response Rate [Up to 2 years 10 months]

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

    3. Duration of Response (DOR) [Up to 2 years 10 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.
