  Purpose
The purpose of this study is to determine if denosumab is non-inferior to zoledronic acid (Zometa®) in the treatment of bone metastases in men with hormone-refractory prostate cancer

Condition Intervention Phase
Bone Metastases Drug: zoledronic acid Biological: denosumab Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: A Randomized, Double-Blind, Multicenter Study of Denosumab Compared With Zoledronic Acid (Zometa®) in the Treatment of Bone Metastases in Men With Hormone-Refractory Prostate Cancer

Primary Outcome Measures:
  • Time to the First On-Study SRE (Non-inferiority) [ Time Frame: Up to 40.5 months ]
    Time to the first on-study skeletal-related event (SRE) analyzed for non-inferiority. Kaplan-Meier estimates of the median and its dispersion are reported.


Secondary Outcome Measures:
  • Time to the First On-Study SRE (Superiority) [ Time Frame: Up to 40.5 months ]
    Time to the first on-study skeletal-related event (SRE), analyzed for superiority of denosumab. Kaplan-Meier estimates of the median and its dispersion are reported.

  • Time to the First-And-Subsequent On-Study SRE [ Time Frame: Up to 40.5 months ]

    Time to the first-and-subsequent on-study skeletal-related event (SRE), analyzed for superiority of denosumab using multiple event analysis, the event must occur at least 21 days after the previous SRE.

    This outcome measure utilizes multiple event times, was analyzed based on a proportional mean model, and is therefore more appropriately summarized by the cumulative mean number of events.
