Abstract
Summary
The long-term efficacy and safety of once-monthly ibandronate were studied in this extension to the 2-year Monthly Oral Ibandronate in Ladies (MOBILE) trial. Over 5Â years, lumbar spine bone mineral density (BMD) increased from baseline with monthly ibandronate 150Â mg (8.4%). Long-term monthly ibandronate is effective and well tolerated for up to 5Â years in women with postmenopausal osteoporosis.
Introduction
Once-monthly therapy with ibandronate has been studied for up to 5Â years in a long-term extension (LTE) to the 2Â year MOBILE trial.
Methods
This multicenter, double-blind extension study of monthly ibandronate involved postmenopausal women who had completed 2 years of the MOBILE core study, with ≥75% adherence. Patients were reallocated, or were randomized from daily therapy, to ibandronate 100 mg monthly or 150 mg monthly for a further 3 years.
Results
A pooled intent-to-treat (ITT) analysis of 344 patients receiving monthly ibandronate from the core MOBILE baseline showed increases over 5Â years in lumbar spine BMD (8.2% with 100Â mg and 8.4% with 150Â mg). Three-year data relative to MOBILE LTE baseline in the full ITT population of all 698 patients randomized or reallocated from MOBILE (including those previously on daily treatment) showed, on average, maintenance of proximal femur BMD gains achieved in the core 2-year study, with further small gains in lumbar spine BMD. In general, maintenance of efficacy was also indicated by markers of bone metabolism.
Conclusions
There were no tolerability concerns or new safety signals. Monthly treatment with ibandronate 100 and 150Â mg is effective and well tolerated for up to 5Â years in women with postmenopausal osteoporosis.
