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

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adults with histologically or cytologically confirmed breast adenocarcinoma
  • radiographic evidence of at least one bone mets
  • Easter Cooperative Oncology Group status of 0, 1 or 2;
  • adequate organ function

Exclusion criteria

Treatment and study plan

Denosumab

Biological

Q4W 120 mg denosumab SC injection and 4 mg zoledronic acid (Zometa) placebo IV over a minimum of 15 minutes

Zoledronic acid

Drug

Q4W 4 mg zoledronic acid IV over minimum 15 minutes and 120 mg denosumab placebo SC

Other names: Zometa

Primary outcomes

  1. 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 outcomes

  1. 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.

  2. 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.
