The Effect of Liraglutide Adjunct to Insulin on Glucagon Response to Hypoglycaemia in Subjects With Type 1 Diabetes

The Effect of Liraglutide Adjunct to Insulin on Glucagon Response to Hypoglycaemia in Subjects With Type 1 Diabetes

This trial is conducted in Europe. The aim of this trial is to investigate if liraglutide adjunct to insulin treatment changes the glucagon response during hypoglycaemia in subjects with type 1 diabetes compared with conventional insulin treatment after 4 weeks' treatment with liraglutide or placebo.

Subjects will initially be randomised to one of the three dose groups, and subsequently randomly allocated to one of two treatment sequences (liraglutide/placebo or placebo/liraglutide).

Inclusion Criteria:

• Type 1 diabetes mellitus (as diagnosed clinically) for at least 12 months prior to randomisation
• Body mass index (BMI) between 20.0 and 28.0 kg/m^2 (both inclusive)

Exclusion Criteria:

• Use of liraglutide or exenatide within 3 months of randomisation
• Recurrent severe hypoglycaemia (more than 1 severe hypoglycaemic event during the last 12 months) or hypoglycaemic unawareness as judged by the trial physician or hospitalisation for diabetic ketoacidosis during the previous 6 months
• Subject who has donated any blood or plasma in the past month or more than 500 mL within 3 months prior to screening
