New prostate cancer drug may cause fewer side effects than current option

NCT ID NCT05526248

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested two drugs, darolutamide and enzalutamide, in 28 men with prostate cancer that had returned after initial treatment. The goal was to see how each drug affects testosterone levels and side effects like breast tenderness. Darolutamide may cause fewer of these side effects because it doesn't enter the brain as easily. The study is small and early, so more research is needed.

What this could mean

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

Active substance

Darolutamide (Nubeqa) and Enzalutamide

What this could lead to

If successful, this study could show that darolutamide causes fewer side effects like breast tenderness while still controlling prostate cancer, offering a better-tolerated treatment option.

What could go wrong

This is a small, early-phase study with only 28 participants, so results may not apply to all patients. It compares two drugs but does not test against a placebo or standard therapy, limiting what can be concluded.
