This is a Long Term Follow Up study to eRADicAte, an open label study designed to examine the effects on concurrent administration of Radium Ra 223 dichloride and Abiraterone Acetate plus Prednisone in subjects with symptomatic castrate resistant prostate cancer and with bone metastases.
31 subjects completed all study visits in the eRADicAte study, and were thus evaluable. All 31 subjects will be asked to participate in this Long Term Follow Up study which will evaluate overall survival, subsequent additional prostate cancer therapies and medications, radiographic changes and SSE's (Symptomatic Skeletal Events), incidence of bone marrow failure, and diagnosis with secondary malignancies.
Living subjects will be evaluated at least 12 weeks after their last dose of Radium Ra 223 dichloride and at each subsequent clinic visit. Deceased subject's data will be obtained retrospectively, from 12 weeks after the eRADicAte End of Treatment visit and prospectively through the date of death. The total duration of the study is expected to be 48 months
