Summary

This study looks at men with advanced prostate cancer that has spread to the bones. Researchers want to see if certain DNA repair problems in the cancer cells make the drug radium-223 work better or worse. The goal is to help doctors choose the best treatment for each patient in the future. About 48 men will take part.
