Radioactive injection targets Hard-to-Treat breast cancer in early trial

NCT ID NCT07340424

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial is testing a radioactive drug called 225Ac-TR2205 in 15 women with advanced triple-negative breast cancer that has spread. The main goal is to see if the drug is safe and tolerable, and to measure how much radiation reaches tumors. It is too early to know if it works, but researchers hope it may one day offer a new treatment option.
