    General information about the trial
    Main objective of the trial
    This study will compare the effectiveness of denosumab treatment every 6 months with once yearly zoledronic acid treatment on bone mineral density (BMD) at various skeletal sites.
    Protection of trial subjects
    This study was conducted in accordance with International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) regulations/guidelines. All subjects provided written informed consent before undergoing any study-related procedures, including screening procedures. The study protocol, amendments, and the informed consent form (ICF) were reviewed by the Institutional Review Boards (IRBs) and Independent Ethics Committees (IECs). No subjects were recruited into the study and no investigational product (IP) was shipped until the IRB/IEC gave written approval of the protocol and ICF and Amgen received copies of these approvals.

    This study was conducted at 37 centers in Belgium, Denmark, Poland, Spain, Canada, United States of America, and Australia. The first participant enrolled on 07 November 2012 and the last participant enrolled on 15 January 2014.

    Pre-assignment
    Screening details
    Participants were randomized in a 1:1 allocation ratio to receive either denosumab or zoledronic acid. Randomization was stratified by screening serum type I collagen C-telopeptide (sCTX) values (< 0.3 ng/mL, 0.3 to 0.5 ng/mL).

    Lumbar Spine Bone Mineral Density (BMD) T-score
    BMD was measured using dual-energy x-ray absorptiometry (DXA) of the lumbar spine. The T-score is a comparison of a person's bone density with that of a healthy 30-year-old of the same sex. Lower scores (more negative) mean lower bone density: A T-score of -2.5 or lower qualifies as osteoporosis and a T-score of -1.0 to -2.5 signifies osteopenia, meaning below-normal bone density without full osteoporosis.

    Percent Change From Baseline in Lumbar Spine Bone Mineral Density at Month 12 - Non-inferiority Analysis
    End point description
    Bone mineral density (BMD) of the lumbar spine was measured by dual-energy x-ray absorptiometry (DXA). DXA scans were analyzed by a central imaging facility. This endpoint was analyzed in the primary efficacy analysis set which includes all randomized participants who have a baseline BMD measurement and at least one postbaseline BMD measurement. Any postbaseline BMD value obtained at the early termination visit was carried forward as the month 12 value (ie, last observation carried forward [LOCF]).
