About this study

This trial tests if the combination of comprehensive metastasis directed therapy delivered by a precision form of external beam radiotherapy (stereotactic ablative radiotherapy), combined with PSMA targeted radiopharmaceutical therapy and cessation of castration, and then followed by testosterone replacement, is an effective treatment for metastatic castration resistant prostate cancer. All patients will be treated with stereotactic ablative radiotherapy and PSMA targeted radiopharmaceutical therapy with cessation of castration. Half of patients are randomized to either receive, or not receive, subsequent testosterone replacement.
