Primary Outcome Measures:
  • Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD), 24 Months/Endpoint, ITT Population. [ Time Frame: Baseline to 24 Months/Endpoint ]
    DXA (dual energy x-ray absorptiometry) assayed on Lunar or Hologic machines. Site will perform at screening to determine if scan should be forwarded to central facility for analysis. Mean of 2 scans performed read by central lab to determine entry qualification. Results standardized (sBMD): Hologic sBMD = 1000 x (BMD x 1.0755), Lunar sBMD = 1000 x (BMD x 0.9522).
