G-Pen™ Compared to Lilly Glucagon for Hypoglycemia Rescue in Adults With Type 1 Diabetes
February 13, 2020 updated by: Xeris Pharmaceuticals
G-Pen™ (Glucagon Injection) Compared to Lilly Glucagon (Glucagon for Injection [RDNA Origin]) for Induced Hypoglycemia Rescue in Adults With T1D: a Phase 3 B Multi-Centered, Randomized, Controlled, Single Blind, 2-Way Crossover Study to Evaluate Efficacy and Safety
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.
