A Study Comparing Denosumab vs. Zoledronic Acid for the Treatment of Bone Metastases in Breast Cancer Subjects.

November 4, 2022 updated by: Amgen

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

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Up to 34 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Up to 34 months
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.
Up to 34 months
