Radioactive bullet targets Hard-to-Treat prostate cancer

NCT ID NCT06052306

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage study tests a new drug called 225Ac-pelgi for people with advanced prostate cancer that has spread and no longer responds to hormone therapy. The drug delivers a short-range radioactive payload directly to cancer cells, aiming to kill them while sparing healthy tissue. The main goals are to find a safe dose and see if it can shrink tumors or lower PSA levels. About 232 participants will receive up to four treatment cycles and be followed for nearly six years.
