Summary

This early-phase study tests a new drug, JNJ-69086420, that delivers a radioactive particle directly to prostate cancer cells. The trial involves about 144 men with advanced prostate cancer that has spread and is no longer responding to standard hormone therapy. The main goals are to find a safe dose and check for side effects, with some early signs of effectiveness also being measured.

Active substance

JNJ-69086420 (a drug that delivers a radioactive particle to prostate cancer cells)

What this could lead to

If it works, this could offer a new treatment option for men with advanced prostate cancer that has stopped responding to other therapies.

What could go wrong

This is a very early phase 1 trial, so the main goal is safety, not effectiveness. The drug may cause serious side effects or not shrink tumors. It is also only for a specific type of advanced prostate cancer.
