Primary Outcome Measures:
  • Bone mineral density (BMD) by dual energy x-ray absorptiometry (DXA) of lumbar spine at 12 months [ Time Frame: 12 Months ] [ Designated as safety issue: No ]
    The primary objective of this study is to evaluate if the effect of administering Denosumab (60 mg subcutaneously [SC] every 6 months [Q6M]) is not inferior to that of Zoledronic Acid (5 mg intravenously [IV] once yearly) in postmenopausal women with osteoporosis previously treated with oral bisphosphonates with respect to change in bone mineral density (BMD) by dual energy x-ray absorptiometry (DXA) of lumbar spine at 12 months

Secondary Outcome Measures:
  • BMD by DXA of total hip at 12 months (non-inferiority); BMD by DXA of lumbar spine at 12 months (superiority); BMD by DXA of total hip at 12 months (superiority) [ Time Frame: 12 Months ] [ Designated as safety issue: No ]
    Secondary Objective(s): Compare the efficacy of administering Denosumab (60 mg SC Q6M) with that of Zoledronic Acid (5 mg IV once yearly) on the following: BMD by DXA of total hip at 12 months (non-inferiority); BMD by DXA of lumbar spine at 12 months (superiority); BMD by DXA of total hip at 12 months (superiority)

Enrollment: 643
Study Start Date: November 2012
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Denosumab 60 mg SC Q6M
Denosumab 60 mg SC Q6M for 12 months and placebo for Zoledronic Acid IV once yearly
Drug: Denosumab
Denosumab 60 mg SC Q6M for 12 months
Active Comparator: Zoledronic Acid 5 mg IV once yearly
Zoledronic Acid 5 mg IV once yearly and placebo for Denosumab SC Q6M for 12 months
Drug: Zoledronic Acid
Zoledronic Acid 5 mg IV once yearly


Ages Eligible for Study:   55 Years and older

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ambulatory postmenopausal women.
  • Age 55 years or older
  • Subject has provided informed consent prior to any study specific procedures
  • Received oral bisphosphonate therapy for osteoporosis at least 2 years prior to screening visit
  • Screening BMD (g/cm2 ) values at the lumbar spine, total hip or femoral neck values of equal to or less than those listed in the protocol.
  • At least 2 lumbar vertebrae and one hip must be evaluable by DXA at the screening visit

Exclusion Criteria:

  • hypothyroidism (stable on thyroid replacement therapy is allowed)
  • hypo- or hyperparathyroidism
  • hypo- or hypercalcemia based on the central laboratory reference ranges
  • Recent tooth extraction (within 6 months of screening visit)

  • Malignancy (except nonmelanoma skin cancers, cervical or breast ductal carcinoma in situ) within the last 5 years
  • Known intolerance to calcium or vitamin D supplements
  • Self-reported alcohol or drug abuse within 12 months prior to screening
  • Currently receiving treatment in another investigational device or drug study, or less than 30 days since ending treatment on another investigational device or drug study(s)
  • History or evidence of any other clinically significant disorder, condition or disease that in the opinion of the Investigator or Amgen physician, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion
