Abstract
AIM: To compare the effect of liraglutide or placebo added on to sodium-glucose co-transporter-2 inhibitor (SGLT2i) ± metformin on glycaemic control in patients with type 2 diabetes. MATERIALS AND METHODS: ) were randomized 2:1 to add-on liraglutide 1.8 mg/day or placebo in this parallel, double-blind, multinational trial. Primary and confirmatory secondary endpoints were changes in HbA1c and body weight from baseline to week 26, respectively. The proportions of patients achieving HbA1c (<7.0%) targets and safety events after week 26 were also assessed. RESULTS: Of 303 patients randomized (one in error), 280 completed treatment. Mean changes in HbA1c from baseline to week 26 with liraglutide (n = 202) and placebo (n = 100) were - 0.98% and - 0.30%, respectively (estimated treatment difference [ETD]: -0.68% [95% CI: -0.89, -0.48]; P < 0.001). Mean body weight changes from baseline were - 2.81 versus -1.99 kg, respectively (ETD: -0.82 kg [95% CI: -1.73, 0.09]; P = 0.077); 51.8% of liraglutide-treated patients achieved HbA1c < 7.0% versus 23.2% receiving placebo (odds ratio: 5.1 [95% CI: 2.67, 9.87]; P < 0.001). More patients treated with liraglutide reported ≥1 treatment-emergent adverse events (66.3%) versus placebo (47.0%). CONCLUSIONS: Liraglutide significantly improved glycaemic control compared with placebo in patients with type 2 diabetes, insufficiently controlled with SGLT2is with/without metformin, with no unexpected safety findings.
