G-Pen™ Compared to Lilly Glucagon for Hypoglycemia Rescue in Adults With Type 1 Diabetes

Completed · Phase 3

Conditions studied: Insulin Hypoglycemia, Type 1 Diabetes Mellitus, Severe Hypoglycemia

In brief

This is a non-inferiority, multi-center, randomized, controlled, single-blind, two-way crossover efficacy and safety study in subjects with Type 1 diabetes mellitus. The study involves two daytime clinical research center (CRC) visits with random assignment to receive G-Pen™ glucagon 1 mg during one period and Lilly Glucagon 1 mg during the other. Each daytime visit is preceded by an overnight stay in the CRC. In the morning of the inpatient study visit, the subject is brought into a state of hypoglycemia through IV administration of regular insulin diluted in normal saline. After a hypoglycemic state with plasma glucose \< 50 mg/dL is verified, the subject is administered a dose of G-Pen or Lilly Glucagon via subcutaneous injection. Plasma glucose levels are monitored for up to 180 minutes post-dosing, with a value of \>70.0 mg/dL within 30 minutes of glucagon administration indicating a positive response. After 3 hours, the subject is given a meal and discharged when medically stable. After a wash-out period of 7 to 28 days, subjects return to the CRC, and the procedure are repeated with each subject crossed over to the other treatment. A follow-up visit as a safety check is conducted 2-7 days following administration of the final dose of study drug.
