Brief Summary:

The primary objective of this study is to compare risedronate 35 mg and placebo with respect to the percent change at 12 months for distal radius trabecular bone volume (BV/TV) in osteopenic postmenopausal women, as measured by three-dimensional peripheral quantitative computed tomography (3D pQCT).

The secondary objectives are to compare the percent change from Screening/Baseline between the 2 treatment groups for the following measurements:

  • Bone mineral density of the lumbar spine, femoral neck, femoral trochanter, and total proximal femur using a dual energy X-ray absorptiometry (DXA) scan at 12 and 24 months;
  • 3D pQCT analysis of distal radius and distal tibia bone microarchitecture data at 6, 12, and 24 months; and
  • Bone turnover markers (BTMs) of:

    • fasting serum carboxyterminal cross linking telopeptide of type 1 bone collagen (CTX 1);
    • serum aminoterminal propeptide of type 1 procollagen (PINP); and
    • urine N-telopeptide cross-links (NTX) at 3, 6, 12, and 24 months.
