Hypoglycemia, Diabetes mellitus
Brief summary
In this study, participants with Type 1 diabetes received insulin through an infusion into a vein to reduce their blood glucose, and then received nasal glucagon (NG) or glucagon for injection under the skin, and their blood glucose was measured for 3 hours. The main objective of this study was to evaluate the safety and efficacy of intranasal and subcutaneous glucagon (SC) in reversing insulin-induced hypoglycemia in participants with type 1 diabetes.
Detailed description
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.
