Phase 3

Completed

• Conditions: Osteoporosis Postmenopausal

• Registration Number: NCT00358176
• Lead Sponsor: Sanofi

Brief Summary

To confirm the non-inferiority of 75 mg risedronate tablets taken on 2 consecutive days per month as compared to 5 mg risedronate tablets taken daily in increasing bone mass in lumbar spine in postmenopausal women with osteoporosis.

To confirm the efficacy of 75 mg risedronate tablets taken on 2 consecutive days per month in postmenopausal women with osteoporosis in increasing bone mass in proximal femur, femoral neck and femoral trochanter and decreasing bone resorption.
