Combining Ipilimumab, Degarelix, and Radical Prostatectomy in Men With Newly Diagnosed Metastatic Castration Sensitive Prostate Cancer or Ipilimumab and Degarelix in Men With Biochemically Recurrent Castration Sensitive Prostate Cancer After Radical Prostatectomy

The purpose of this study is to find out what effects, good and/or bad, taking ipilimumab with degarelix before surgery to remove the prostate, followed by more degarelix and ipilimumab after the surgery, will have on prostate cancer. The goal of this trial is to assess the safety and efficacy of a multimodality approach combining hormones and immunotherapy in prostate cancer populations that are considered incurable and standardly treated with hormones alone, and represent clinical states prior to development of castration-resistant disease. There are 2 cohorts. The first will use ipilimumab and degarelix prior to and following radical prostatectomy in men with newly diagnosed, oligometastatic, castration-sensitive disease. The second cohort will include men who have already received definitive local therapy with radical prostatectomy but have since experienced biochemical and/or metastatic recurrence.
