Experimental combo aims to rev up immune system against Hard-to-Treat prostate cancer

NCT ID NCT05445609

First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether combining two drugs—vidutolimod and nivolumab—can help the immune system attack metastatic castration-resistant prostate cancer. Nivolumab blocks a protein that shuts down immune cells, while vidutolimod is designed to train those cells to target tumors. The study planned to enroll 10 men whose cancer had progressed after other treatments, but it is currently suspended.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

vidutolimod (CMP-001) and nivolumab

What this could lead to

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

What could go wrong

This is a very small, early-phase trial (only 10 participants) and is currently suspended. The treatment may not shrink tumors or improve survival, and side effects from immune therapy can be severe.
