Official title
G-Pen (Glucagon Injection) Compared to GlucaGen® Hypokit® (Glucagon) for Induced Hypoglycemia Rescue in Adults With T1D: A Phase 3 Multi-center, Randomized, Controlled, Single Blind, 2-way Crossover Study to Evaluate Efficacy and Safety
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a 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 Novo 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 severe hypoglycemia through IV administration of regular insulin diluted in normal saline. After a hypoglycemic state with plasma glucose \< 54 mg/dL (3 mmol/L) is verified, the subject is administered a dose of G-Pen or Novo Glucagon via subcutaneous injection. Plasma glucose levels are monitored for up to 180 minutes post-dosing, with a value of \>70.0 mg/dL (3.89 mmol/L) or an increase of \> 20 mg/dL (\>1.11 mmol/L) 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 procedures 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.
