  Purpose
The purpose of this study is to determine if denosumab is non-inferior to zoledronic acid in the treatment of bone metastases in subjects with advanced breast cancer.

Condition Intervention Phase
Bone Metastases
Biological: Denosumab
Drug: Zoledronic Acid
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
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 Subjects With Advanced Breast Cancer

Primary Outcome Measures:
  • Time to First On-Study Skeletal Related Event (SRE) (Non-inferiority) [ Time Frame: Up to 34 months ]
    Time to first on-study skeletal-related event (SRE) using a non-inferiority analysis. The median time to first skeletal-related event could not be estimated in one treatment arm, so the subject incidence is presented.


Secondary Outcome Measures:
  • Time to First On-Study Skeletal-Related Event (Superiority) [ Time Frame: Up to 34 months ]
    Time to first on-study skeletal-related event (SRE) using a superiority analysis. The median time to first skeletal-related event could not be estimated in one treatment arm, so the subject incidence is presented.

  • Time to First and Subsequent On-Study Skeletal-Related Event [ Time Frame: Up to 34 months ]
    Time to first and subsequent on-study skeletal-related event (SRE) using a multiple event analysis. To be considered a subsequent SRE, 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 number of events.
