Type 1 diabetes is associated with an almost threefold higher mortality rate than the general population, primarily driven by excess mortality from cardiovascular disease. Insulin sensitivity evaluated by the estimated glucose disposal rate (eGDR) is a recognized predictor of cardiovascular disease. Here, we evaluated the effect of adjunctive therapy with the glucagon-like peptide 1 receptor agonist (GLP-1RA) liraglutide on eGDR in patients with type 1 diabetes. We calculated eGDR post-hoc in a randomized (1:1) , placebo-controlled, double-blind, clinical trial (NCT01612468) that evaluated the effect of liraglutide 1.8 mg once daily (uptitrated via 0.6 mg and 1.2 mg over 2 weeks) as add-on to insulin treatment compared with placebo in 100 overweight persons with type 1 diabetes (35/65 women/men, age 48 (12) years (mean (standard deviation)) , diabetes duration 23 (12) years, BMI 30 (3) kg/m2, glycated hemoglobin A1c 8.7 (0.7) % / 72 (8) mmol/mol) . After 12 weeks of treatment, liraglutide significantly increased eGDR compared with placebo. However, at end of treatment at week 26, the between-group difference was not statistically significant (Table 1) . These data indicate that liraglutide may improve eGDR, a recognized predictor of cardiovascular disease, in overweight persons with long-standing type 1 diabetes and inadequate glycemic control.
