Summary

This phase 2 study tests a radioactive antibody, Ac-225 rosopatamab tetraxetan, that seeks out and delivers radiation directly to prostate cancer cells. It is for men with a specific type of advanced prostate cancer that has stopped responding to hormone therapy. The trial aims to find the best dose and evaluate how well the treatment shrinks tumors or lowers PSA levels.
