Primary Outcome Measures:
  • Effects of lasofoxifene compared to placebo on Bone Mineral Density (BMD) changes at the spine and hip after 1 year of treatment [ Time Frame: 12 months ]
    Percent change from baseline in lumbar spine BMD at Month 12

Secondary Outcome Measures:
  • Hip BMD, bone markers, lipids and new radiographic vertebral fractures at 1 year [ Time Frame: Month 6 and Month 12 ]
    Percent change from baseline in lumbar spine BMD at Month 6, percent change in baseline in hip BMD at Month 6 and Month 12, percent change from baseline in bone metabolism markers at Month 6 and Month 12, percent change from baseline in serum lipids, total cholesterol, high-density lipoprotein cholesterol, triglycerides, lipoprotein (a), apoliporpotein-A1, apolipoprotein-B at Month 6 and Month 12 and incidence of new vertebral fractures at Month 12
