Study Summary

This trial is testing a new drug to see what dose is safe and effective.

Who is the study for?
This trial is for men with advanced prostate cancer that has spread, who have already tried at least one type of hormone therapy or chemotherapy. They should be relatively healthy and active (ECOG status 0-1), not have major heart issues, clotting diseases, infections like hepatitis B/C or HIV, autoimmune diseases, lung problems, or any other cancers in the last two years.Check my eligibility
What is being tested?
The study is testing JNJ-78278343's optimal dose for safety and effectiveness in two parts: first finding the right dose (Dose Escalation) and then confirming its safety at this dose level (Dose Expansion).See study design
What are the potential side effects?
While specific side effects are not listed here, similar treatments often cause immune reactions since they target proteins on cancer cells which can affect normal cells too. This might lead to flu-like symptoms, fatigue, skin reactions among others.

Experimental Treatment
Group I: JNJ-78278343Experimental Treatment1 Intervention
Participants will receive JNJ-78278343 either subcutaneously (SC injection or SC infusion) or intravenous (IV) infusion. The dose levels will be escalated based on the dose limiting toxicities (DLT) evaluation by the study evaluation team (SET) in Part 1 (dose escalation). In Part 2 (dose expansion), participants will receive JNJ-78278343 either SC or IV at recommended phase 2 dose (RP2D) as determined in Part 1.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is enrollment currently open for participation in this trial?

"As reported on clinicaltrials.gov, this research endeavour is in the process of sourcing participants. It was posted initially on July 13th 2021 and recently updated on November 22nd 2022."

Answered by AI

What ultimate effects are investigators hoping to observe with this clinical investigation?

"The principal purpose of this prolonged (over one year and ten months) clinical trial is to determine the occurrence rate of dose-limiting toxicity. Secondary objectives involve measuring serum concentrations of anti-JNJ78278343 antibodies, prostate specific antigen levels, as well as calculating PSA response rates by evaluating any decline from baseline values that are greater than 50%."

Answered by AI

How many participants have been recruited for this experiment?

"Affirmative. According to the clinicaltrials.gov, this medical study is actively recruiting subjects that meet the criteria it posted on July 13 2021 and updated on November 22 2022. The research project requires 110 patients from 3 sites for its completion."

Answered by AI

What potential risks are posed by JNJ-78278343?

"Due to the limited supporting evidence for JNJ-78278343's efficacy and safety, our team at Power judged it a score 1 on the scale of 1 to 3."
