New hope for Hard-to-Treat prostate cancer: enhertu trial launches
NCT ID NCT06610825
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests Enhertu, a targeted drug, in 60 men with HER2-positive prostate cancer that has spread and stopped responding to hormone therapy and newer drugs like abiraterone. Participants must have tried or refused chemotherapy. The study measures tumor shrinkage and how long the cancer is controlled.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Enhertu (fam-trastuzumab deruxtecan-nxki)
- What this could lead to
- If it works, this could offer a new treatment option for men with HER2-positive prostate cancer that has stopped responding to hormone therapy and chemotherapy.
- What could go wrong
- This is a small, early-phase trial with only 60 people, so results may not apply to everyone. Enhertu can cause serious side effects like lung inflammation or heart problems.
