Liraglutide as add-on to Insulin in Type 1 Diabetes

Treatment With Liraglutide as add-on to Insulin in Type 1 Diabetic Patients. Effects on Glycemic Control and Counterregulation and Cognitive Performance During Hypoglycaemia

The purpose of this study is to:

Part 1:

To investigate how 12 weeks treatment with liraglutide affects glycemic control in poorly controlled patients and how the treatment affects gastric emptying rate during hypoglycemia.

Part 2:

To investigate how 12 weeks treatment of type 1 diabetic patients with liraglutide affects counterregulatory hormones and cognitive performance during hypoglycemia.
