Conditions

Osteopenia

Brief summary

The primary purpose of the protocol is to evaluate the sensitivity of 3D-pQCT (3D-Peripheral Quantitative Computed Tomography) technology to detect minute changes in bone microarchitecture.

Detailed description

The 3D-pQCT equipment allows the evaluation of changes occurring within the bone at microarchitecture level, without the need for invasive bone biopsies. The primary objective is to evaluate the sensitivity of the technology to detect a difference between those treated with risedronate 35mg OAW (once a week) or placebo. Early phase postmenopausal women with osteopenia have been chosen because they have a more rapid and higher level of bone loss during the first few years of the menopause.

Trabecular Bone Volume to Tissue Volume at Distal Radius, Percent Change From Baseline to Month 12

Time frame: Baseline and Month 12

Population: Primary Efficacy Population - all patients in ITT population who had no major protocol violations and had an evaluable distal radius BV/TV (trabecular bone volume to tissue volume) at baseline and Month 12.

Comparison: In Laib 1998, the mean and SD of the annual loss in distal radius BV/TV were reported to be 3.5% and 6.4%, respectively. Assuming the treatment difference and SD of the percent change in distal radius BV/TV for this study were the same, it required enrolling 52 patients for placebo and 104 for risedronate to ensure 80% power to achieve 0.05 level of significance.
