New radioactive cocktail shows promise for tough prostate cancers

NCT ID NCT03939689

First seen Nov 01, 2025 · Last updated May 05, 2026 · Updated 30 times

Summary

This study tested a radioactive drug (I-131-1095) plus a standard hormone therapy (enzalutamide) in 120 men with advanced prostate cancer that had stopped responding to another treatment (abiraterone). The goal was to see if the combination could shrink tumors and lower PSA levels more than enzalutamide alone. While the treatment aims to control the disease, it is not a cure, and ongoing management is still needed.
