New radioactive drug targets Hard-to-Treat prostate cancer
NCT ID NCT07381582
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tests a new radioactive drug, 161Tb-LNC1011, in 15 men with advanced prostate cancer that no longer responds to hormone therapy. The drug is designed to seek out and deliver radiation directly to cancer cells. The main goals are to check safety and find the best dose, while also seeing if it can shrink tumors or lower PSA levels.
