Study Summary

This trial is researching the safe dose of two new drugs for cancer treatment.

Who is the study for?
This trial is for men with advanced prostate cancer that's resistant to hormone therapy and has spread. They should have tried at least one other treatment like abiraterone or chemotherapy, be relatively healthy (ECOG status of 0 or 1), and have adequate organ function. Men can't join if they've had recent autoimmune disease treatments, unresolved side effects from previous cancer therapies (except minor nerve damage or hair loss), transplants, serious infections, heart/lung problems, or allergies to the drugs being tested.Check my eligibility
What is being tested?
The study is testing a combination of two drugs: JNJ-78278343 and Cetrelimab in patients with metastatic castration-resistant prostate cancer. The first part will find the best doses to use while checking safety. The second part will see how safe these doses are when more people take them.See study design
What are the potential side effects?
Possible side effects include reactions related to the immune system since both drugs work by boosting it—this could lead to inflammation in different parts of the body. There might also be typical drug infusion reactions as well as general fatigue and issues affecting organs due to increased immune activity.

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)
