Details and patient eligibility

About

This is a blinded, randomized crossover study to compare the safety and efficacy of G-Pen (glucagon injection) to Lilly Glucagon (glucagon for injection [rDNA origin]) for hypoglycemia rescue of adult patients with type 1 diabetes.

Full description

This is a blinded, randomized, Phase 3 comparative efficacy and safety study in adults with type 1 diabetes. Patients will complete screening procedures up to 60 days before randomization to determine eligibility before enrollment to the treatment phase.

The procedure for evaluating the efficacy of the G-Pen (glucagon injection) consists of inducing hypoglycemia by intravenous administration of regular insulin diluted in normal saline. Each participant will undergo two episodes of insulin-induced hypoglycemia, and in random order will receive 1 mg G-Pen (glucagon injection) during one episode and 1 mg Lilly Glucagon during the other episode. There will be wash out period of 7-28 days between treatment visits.

Blood glucose levels will be monitored post-dosing, with a return of plasma glucose to a concentration > 70 mg/dL within 30 minutes signifying successful hypoglycemia rescue. As a confirmation of efficacy, subjects will complete a questionnaire concerning changes in symptoms of hypoglycemia following treatment with glucagon.

Subjects will return for a follow-up safety visit 3-14 days following administration of the final dose of glucagon.
