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)


Estimated Enrollment: 620
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

Detailed Description:

The rationale for this study is to evaluate whether patients who switch from oral biphosphonates to Denosumab have greater BMD gains than those who switch from oral biphosphonates to Zoledronic Acid.

  Eligibility

Ages Eligible for Study:   55 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

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:

  • Received other osteoporosis treatment or bone active treatment
  • Evidence of history of any of the following:
  • hyperthyroidism (stable on antithyroid therapy is allowed)
  • 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)
  • Paget disease of bone (subject report or chart review)
  • other bone diseases which affect bone metabolism (eg, osteopetrosis, osteogenesis imperfecta) (chart review)
  • Abnormalities of the following per central laboratory reference ranges:

    • vitamin D deficiency (25[OH] vitamin D level < 20 ng/mL), repletion will be allowed and subjects may be re-screened
    • hypercalcemia
  • History of any solid organ or bone marrow transplant
  • 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
