N2 - OBJECTIVE: Patients with type 2 diabetes have an increased risk of fragility fractures; the cause is unclear, but is likely multifactorial. Some diabetes treatments induce bone loss, accentuating underlying skeletal fragility and increasing fracture risk. This subgroup analysis aimed to compare long-term effects of liraglutide and glimepiride on bone mineral density (BMD) in patients with type 2 diabetes.METHODS: LEAD-3, a 52-week, double-blind, active-control, phase III, multicenter trial, investigated the efficacy of liraglutide (1.2 and 1.8 mg/day) versus glimepiride monotherapy in type 2 diabetes. A 52-week, open-label extension followed, in which participants remained on randomized therapy. A subgroup of participants underwent BMD measurement by dual energy X-ray absorptiometry at baseline, 52, and 104 weeks. The main outcome measure was change from baseline in total body BMD at 52 and 104 weeks, analyzed by ANCOVA.RESULTS: 746 patients with type 2 diabetes aged 19-79 years were randomized into the main trial. Of these, 61 patients (20 assigned to liraglutide 1.8 mg/day, 23 to liraglutide 1.2 mg/day, 18 to glimepiride 8 mg/day) had BMD measurements. Baseline age, BMI, diabetes duration, HbA1c, and total BMD were similar across treatment groups. There was no apparent difference in mean total BMD change from baseline in patients receiving liraglutide 1.8 or 1.2 mg/day, or glimepiride 8 mg/day at 52 or 104 weeks.CONCLUSIONS: In this small subgroup analysis, liraglutide monotherapy did not negatively affect total BMD in a 2-year prospective study, suggesting it may not exacerbate the consequences of bone fragility.
