Safety and Efficacy of a Novel Glucagon Formulation in Type 1 Diabetic Patients Following Insulin-induced Hypoglycemia

In the study, up to four (4) treatments were administered as a single dose either intranasally or subcutaneously to eighteen (18) male or female participants under fasting conditions and following the use of insulin to lower blood glucose. The participants were assigned at random to a group that received one treatment for each of the 3 study periods. The glucagon administrations were separated by approximately 7 calendar days. For 2 participants, a single dose of 3 mg NG was administered at the 4th period that was separated by at least 21 calendar days from the 3rd period.
