| Main Objective: to demonstrate that the percent change in lumbar spine BMD at Month 12 relative to baseline in male and female patients treated with one iv zoledronic acid 5 mg dose at randomization is not inferior to the percent change in lumbar spine BMD at Month 12 compared to baseline in those patients who are treated with oral risedronate 5 mg daily. ;Secondary Objective: • To assess the percent change in BMD at the total hip, femoral neck, trochanter, and distal radius at Month 6 and Month 12 relative to baseline in patients treated with zoledronic acid compared to patients treated with risedronate. • To assess changes in biochemical markers of the bone turnover at Day 10, Month 3, Month 6, and Month 12 relative to baseline in patients treated with zoledronic acid compared to patients treated with risedronate. • To evaluate the overall safety of zoledronic acid compared to risedronate in patients receiving corticosteroid therapy.;Primary end point(s): • DXA measurements of the lumbar spine, hip and distal radius at baseline, Months 6 and 12. • Height Measurements at baseline, Months 6 and 12. • Bone Marker Analysis (specialized serum tests for CTx, P1NP, bone specific alkaline phosphatase and urinary NTx - markers associated with osteoporosis yet to be identified could be performed in addition) prior to receiving the first dose of study drug and at all subsequent visits until Month 12. • Clinical and morphometric fractures • Lateral X-ray of the lumbar and thoracic spine to assess vertebral fractures at baseline and month 12 | — |
