First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time

Summary

This early-stage trial tests whether adding CP-PCA07 (a form of niclosamide, a drug used for tapeworm infections) to the standard drug enzalutamide can safely help men with castration-resistant prostate cancer that has stopped responding to treatment. The study involves 18 men and aims to find the best dose and check for side effects, while also measuring changes in PSA levels and tumor response.
