What this study is about

This trial is testing a treatment of Bipolar Androgen Therapy (BAT) plus Radium-223 (RAD) for men with metastatic castration-resistant prostate cancer. Men who have received hormone therapy and whose cancer has returned will be enrolled in it, which involves giving Radium-223 every 28 days for six cycles along with Testosterone Cypionate injections until the treatment causes unacceptable side effects or the cancer progresses.
