Information provided by (Responsible Party):
Warner Chilcott
  Purpose
The purpose of this trial is to compare the difference in bone microarchitecture of the distal radius at month 12 in postmenopausal osteopenic women treated with risedronate 150mg taken once a month compared to placebo.

Condition Intervention Phase
Osteoporosis Drug: placebo Drug: risedronate Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A 12-month, Multicenter, Double-blind, Randomized, Parallel Group Study Comparing 150 mg Once-a-month Risedronate and Placebo Using 3-dimensional Micro MRI (Magnetic Resonance Imaging).

Primary Outcome Measures:
  • Percent Change From Baseline in Erosion Index (A Ratio of Curve-like Structures to Plate-like Structures and is a Measure of the Degree of Structural Degradation) of the Distal Radius [ Time Frame: 12 months ]

    The percent was change from baseline in erosion index at the distal radius between the risedronate and placebo groups at Month 12 (the lower the percent change in erosion index, the greater the improvement of structural degradation); the last valid postbaseline measurement was to be used when the Month 12 value was missing (Last Observation Carried Forward or LOCF).

    NOTE: The study was unable to recruit sufficient numbers of patients to meet with the protocol specified numbers, thus it was terminated early after 5 months. No efficacy analyses were performed.



Secondary Outcome Measures:
  • Erosion Index of the Distal Radius [ Time Frame: 6 months ]
    Study was terminated prior to acquiring any efficacy endpoints. No efficacy analyses were performed.
