E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to compare risedronate 35 mg and placebo with respect to percent change at 12-month for distal radius trabecular bone volume (BV/TV) in osteopenic postmenopausal women as measured by 3D-pQCT. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to compare the percent change from Screening/Baseline between the 2 treatment groups for the following measurements: · BMD of the lumbar spine, femoral neck, femoral trochanter, and total proximal femur using dual-energy X-ray absorptiometry (DXA) scan at 12, and 24 M ; · 3D-pQCT analysis of distal radius and distal tibia bone microarchitecture data at 6, 12, and 24 M ; · 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 NTX at 3, 6, 12 and 24 M.

E.5 End points |
E.5.1 | Primary end point(s) |
3-D-pQCT Data—Microarchitectural Parameters (Distal Radius BV/TV Measurements)
The primary efficacy assessment in this study will be BV/TV percent change from Baseline at distal radius as measured in the non-dominant wrist at Month 12. If there is a history of prior fracture (traumatic or atraumatic) in the non-dominant wrist, the dominant wrist will be used.
Measurements will be taken using Xtreme CT scanners supplied by SCANCO Medical AG, (Bassersdorf, Switzerland) who will be responsible for the analysis and central reading of the radiological images. |
