Brief summary
The purpose of this study is to describe the safety and tolerability of up to 5 years (ie, 3 years under the 20040138 Amgen study and 2 years on this study) denosumab administration as measured by adverse events, immunogenicity, and safety laboratory parameters in subjects who previously received denosumab for non-metastatic prostate cancer.
Interventions
60 mg SC of Denosumab will be administered on study day 1, month 6, month 12, and month 18
