Summary

This early-stage study tests a new radioactive drug called AB001 in 80 men with advanced prostate cancer that has stopped responding to hormone therapy. The drug delivers a powerful alpha radiation dose directly to cancer cells. The main goals are to check safety and find the best dose and schedule for future studies.
