A Study of Bonviva (Ibandronate) in Women With Post-Menopausal Osteoporosis Who Have Received Previous Bonviva Treatment

Open Label, Parallel Group, Multicenter Study of Two Intravenous (IV) Ibandronate Dose Regimens (2 mg Every 2 Months and 3 mg Every 3 Months) in Women With Postmenopausal Osteoporosis Who Completed Trial BM16550

This 2-arm study was designed to assess the long-term safety and tolerability of intravenous (IV) treatment with 2 mg or 3 mg Bonviva in women with post-menopausal osteoporosis who had previously completed Bonviva study BM16550 (DIVA study; NCT00048074). Patients received Bonviva either 2 mg IV every 2 months, or 3 mg IV every 3 months. Patients also received daily supplementation with vitamin D and calcium. The anticipated time on study treatment was 2+ years, and the target sample size was 500+ individuals.

3 mg IV every 3 months for 3 years. All patients received a minimum of calcium 500 milligrams/day (upper limit 1500 mg/day) and Vitamin D 400 Internation Units/day (IU/day).

2 mg IV every 2 months for 3 years. All patients received a minimum of calcium 500 milligrams/day (upper limit 1500 mg/day) and Vitamin D 400 Internation Units/day (IU/day).

Relative Percent Change From Baseline in Mean Lumbar Spine Bone Mineral Density (BMD) at 12, 24 and 36 Months

Relative change percent(%) from baseline of MA17904 and BM16550 (NCT00048074) in mean lumbar spine (L2-L4) BMD at 12, 24 and 36 months (i.e., 3, 4 and 5 years after initiation of BM16550)- Study MA17940.Percent change=[(measure at time t - measure at baseline)/measure at baseline]*100%, where t=12, 24 and 36 months. The baseline value is used as a reference to calculate the relative change from baseline.

Relative change percent (%) from baseline of MA17904 and BM16550 (NCT00048074) in mean total hip BMD at 12, 24 and 36 months (i.e., 3, 4 and 5 years after initiation of BM16550)- Study MA17904. Percent change=[(measure at time t - measure at baseline)/measure at baseline]*100%, where t=12, 24 and 36 months. The baseline value is used as a reference to calculate the relative change from baseline.

Relative Percent Change From Baseline in Serum C-telopeptide Crosslinks of Type I Collagen (CTX) at Trough at 6, 12, 24 and 36 Months

Relative percent (%) change from baseline of MA17904 and BM16550 (NCT00048074) in serum C-telopeptide crosslinks of type I collagen (CTX) at trough at 6, 12, 24 and 36 months- Study MA17904. Percent change=[(measure at time t - measure at baseline)/measure at baseline]*100%, where t=6, 12, 24 and 36 months. The baseline value is used as a reference to calculate the relative change from baseline.

Relative percent (%) change from MA17904 baseline of post-dose suppression of serum C-telopeptide crosslinks of type I collagen (CTX) at 6 months- Study MA17904. Percent change=[(measure at time t - measure at baseline)/measure at baseline]*100%, where t= 6 months. The baseline value is used as a reference to calculate the relative change from baseline.
