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

Hoffmann-La Roche781 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

Time frame: Baseline,12, 24 and 36 months

Secondary Outcomes

Relative Percent Change From Baseline in Mean Total Hip BMD at 12, 24 and 36 Months

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.

Time frame: Baseline,12, 24 and 36 months

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.

Time frame: Baseline, 6, 12, 24 and 36 months (i.e., 2.5, 3, 4 and 5 years after initiation of BM16550)

Relative Percent Change From Baseline in Post-dose Suppression of Serum CTX at 6 Months

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.
