BACKGROUND: New treatments for type 2 diabetes mellitus are needed to retain insulin-glucose coupling and lower the risk of weight gain and hypoglycaemia. We aimed to investigate the safety and efficacy of liraglutide as monotherapy for this disorder. METHODS: In a double-blind, double-dummy, active-control, parallel-group study, 746 patients with early type 2 diabetes were randomly assigned to once daily liraglutide (1.2 mg [n=251] or 1.8 mg [n=247]) or glimepiride 8 mg (n=248) for 52 weeks. The primary outcome was change in proportion of glycosylated haemoglobin (HbA(1c)). Analysis was done by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NTC00294723. FINDINGS: At 52 weeks, HbA(1c) decreased by 0.51% (SD 1.20%) with glimepiride, compared with 0.84% (1.23%) with liraglutide 1.2 mg (difference -0.33%; 95% CI -0.53 to -0.13, p=0.0014) and 1.14% (1.24%) with liraglutide 1.8 mg (-0.62; -0.83 to -0.42, p<0.0001). Five patients in the liraglutide 1.2 mg, and one in 1.8 mg groups discontinued treatment because of vomiting, whereas none in the glimepiride group did so. INTERPRETATION: Liraglutide is safe and effective as initial pharmacological therapy for type 2 diabetes mellitus and leads to greater reductions in HbA(1c), weight, hypoglycaemia, and blood pressure than does glimepiride.
