Liraglutide in Type 1 Diabetes
Summary
A randomised, double-blind, placebo controlled study of the effect of liraglutide as an additional treatment to insulin on HbA1c, body weight and hypoglycaemia in poorly regulated type 1 diabetes patients. Background: Treatment with glucagon-like peptid 1 (GLP-1) agonists liraglutide and exanatide leads to weight loss and decrease in haemoglobin A1c in oral anti diabetic treated type 2 diabetes patients. It is estimated that 40-50 % of type 1 diabetes patients in the US suffers from overweight or poor glycaemic control (HbA1c \> 8 %). Small studies, not placebo controlled, reports effects of adding liraglutide to a group of well regulated (HbA1c \< 7.5 %) normal to overweight insulin treated type 1 diabetes patients for 24 weeks. A decrease in HbA1c, weight, insulin doses and glycaemic excursions measured by continuous glucose monitoring was seen. Primary objective:To investigate the effect of liraglutide 1.8 mg once daily compared to placebo for 24 weeks on change in HbA1c in patients with type 1 diabetes as an add-on therapy to insulin. Secondary objectives:To investigate the effect of liraglutide as an add-on therapy to insulin compared to placebo on change in:Weight, insulin dose,hypoglycaemic events, CGM, BMI, body composition, quality of life, treatment satisfaction,food preferences, meal test, CIMT, PWV and 24 hour blood pressure.
