Abstract
Summary Long-term bone mineral density (BMD) gains, bone marker levels, and safety of 3 mg quarterly intravenous (IV) ibandronate were studied in this 3-year extension to the Dosing IntraVenous Administration (DIVA) trial. Quarterly IV ibandronate consistently increased lumbar spine bone mineral density measured with dual-energy X-ray absorptiometry (DXA-BMD) over 5 years (8.1%) and was well tolerated in women with postmenopausal osteoporosis. Introduction Treatment with IV ibandronate regimens, 2 mg bimonthly and 3 mg quarterly, has been studied for up to 5 years in a long-termextension (LTE) to the 2-year DIVAtrial. Methods DIVA LTE is an open-label extension to a 2-year randomized, double-blind, double-dummy, noninferiority, phase III study (DIVA core). DIVA LTE involved postmenopausal women who had completed 2 years of DIVA core, comparing daily oral and IV ibandronate (≫75% adherence with IV ibandronate in year 2 of DIVA). Patients previously treated with 2 mg bimonthly or 3 mg quarterly IV ibandronate continued on the same regimen; patients who had received 2.5 mg daily oral ibandronate and placebo IV in DIVA core were switched to IV ibandronate. Results Pooled analysis of 497 intent-to-treat (ITT) patients receiving IV ibandronate from DIVA core baseline showed consistent increases over 5 years in lumbar spine DXABMD (8.4% [95% confidence interval (CI)=7.5, 9.3] with 2 mg bimonthly and 8.1% [95% CI=7.2, 8.9] with 3 mg quarterly). Three-year data relative to DIVA LTE baseline in the full ITT population (756 patients randomized or reallocated from DIVA, including those previously on daily treatment) showed maintenance of DXA-BMD gains from DIVA core with further gains in lumbar spine DXA-BMD. These benefits are supported by sustained reductions in markers of bone metabolism. No tolerability concerns or new safety signals were observed. Conclusions Treatment with IV ibandronate 2 mg bimonthly or 3 mg quarterly is effective and well tolerated for up to 5 years in women with postmenopausal osteoporosis.
