  Purpose
The study will evaluate the efficacy and safety of transitioning postmenopausal women on current alendronate therapy to denosumab. Endpoints studied will include bone mineral density, bone turnover markers and bone histology in a subset of subjects.

Condition Intervention Phase
Postmenopausal Osteoporosis Drug: alendronate Drug: Denosumab (AMG 162) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized Study to Evaluate Safety and Efficacy of Transitioning Therapy From Alendronate to Denosumab (AMG 162) in Postmenopausal Women With Low Bone Mineral Density

Further study details as provided by Amgen:

Primary Outcome Measures:
  • Percent Change From Baseline in Total Hip Bone Mineral Density [ Time Frame: Baseline, 12 months ]
    Bone Mineral Density Assessed by Dual Energy X-Ray Absorptiometry. Percent change calculated using [(12 month value - baseline value) / baseline value]*100.


Secondary Outcome Measures:
  • Percent Change From Baseline in Lumbar Spine Bone Mineral Density [ Time Frame: Baseline, 12 months ]
    Bone Mineral Density Assessed by Dual Energy X-Ray Absorptiometry. Percent change calculated using [(12 month value - baseline value) / baseline value]*100.

  • Percent Change From Baseline in Serum C-Telopeptide-I (CTX-I) [ Time Frame: Baseline, 3 months ]
    Percent Change From Baseline to Month 3 in Serum CTX-I. Percent change calculated using [(3 month value - baseline value) / baseline value]*100.
