Glucagon and Advanced HCL System to Prevent Exercise-Induced Hypoglycaemia in People With Type 1 Diabetes

The study consists of a screening visit (visit A) and two additional study visits (visit B and visit C) completed in a sequential order. During study visit B participants will receive s.c. administration of 150 ug glucagon prior to a 45-min moderate intensity continuous exercise session and subsequently continue into a 1-hour post-exercise observation period. During study visit C the exact same procedures will be followed with the omission of glucagon.
