NCT ID NCT03123978

First seen May 14, 2026 · Last updated May 14, 2026

Summary

This early-stage trial tested a combination of two drugs—enzalutamide, a standard hormone therapy, and niclosamide, a drug usually used for tapeworm infections—in 6 men with castration-resistant prostate cancer that had spread or returned. The goal was to find the safest dose and identify side effects. The study was completed but did not report major breakthroughs, and patients still require ongoing treatment.
