About this trial
The objective of the study is to evaluate whether pre-exercise administration of low-dose subcutaneous glucagon prevents or attenuates exercise-induced declines in plasma glucose concentration during and after moderate-intensity continuous exercise (MICE) performed approximately 90 minutes after a meal in adults with type 1 diabetes using an automated insulin delivery (AID) system.
The primary endpoint is the difference in the change in plasma glucose (PG) from exercise initiation to the nadir during exercise and through the 2-hour post-exercise period between the glucagon (GCN) and carbohydrate (CHO) visits.
