Brief summary

The purpose of the study is to learn more about different devices for delivering glucagon during simulations of severe hypoglycemic (low blood sugar) emergencies. The study will be carried out using medical manikins to simulate real life scenarios. No drug will be administered to humans. Part A will last approximately 17 days for Trained Users and Participants with Diabetes (PWD). Part B will last approximately nine (9) days for Untrained Users. Each part will be separated by approximately 7 days.

Recruitment details

Trained Users were recruited alongside a participant with diabetes (PWD) with whom they were familiar. They were given a level of training intended to mimic that of a real-life caregiver on both devices: glucagon emergency kit (GEK) and nasal glucagon (NG). Untrained Users who have limited knowledge of severe hypoglycemia did not receive training.

Pre-assignment details

Trained users participated in Part A and untrained users participated in Part B.
