1094-P: Short-Acting Exenatide and Markers of Cardiovascular Disease in Type 1 Diabetes: A Randomized, Double-Blinded, Placebo-Controlled Trial

In type 2 diabetes, some glucagon-like peptide 1 receptor agonists (GLP-1RAs) reduce the risk of major adverse cardiovascular events. Whether GLP-1RAs have any effect on cardiovascular disease risk in patients with type 1 diabetes remains to be elucidated. We tested the effect of adding the short-acting GLP-1RA exenatide to insulin treatment on markers of cardiovascular risk in type 1 diabetes. In a randomized, double-blinded, parallel-group trial, 108 individuals with type 1 diabetes aged ≥18 years on multiple daily insulin injection therapy with body mass index >22.0 kg/m2 and HbA1c 7.5-10.0% (59-88 mmol/mol) were randomized (1:1) to preprandial subcutaneous injection of 10 µg exenatide (Byetta®) or placebo three times daily over 26 weeks as add-on treatment to existing insulin therapy. Reported data were secondary endpoints and analyzed in a baseline-adjusted linear mixed model in the intention-to-treat population. Exenatide changed total fat mass by -2.6 kg (95% CI -3.6;-1.6, P
