A Study of Glucagon Administered in Different Forms and Routes to Healthy Adults

A Single Site, Randomized, Four-Way, Four-Period PK/PD Crossover Phase 1 Clinical Study in 16 Fasted Healthy Adult Volunteers Receiving 3 Dose Levels of Intranasally Administered Glucagon and One Dose Level of Glucagon Administered by Subcutaneous Injection

The main purpose of this study was to evaluate the safety and tolerability of nasal glucagon (NG). The study drug was delivered into the participant's nostril (intranasally) or was given as an injection just under the skin (subcutaneously) once in each of four study periods. The study lasted about 23 days for each participant.

Inclusion Criteria:

Exclusion Criteria:

• Presence of any nose piercings.
• History of significant hypersensitivity to glucagon or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs.
• Presence of significant gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs or known to potentiate or predispose to undesired effects.
• Presence of significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic or dermatologic disease.
• Presence of clinically significant findings on nasal examination and bilateral anterior rhinoscopy.
• Fasting blood glucose above 5.0 millimoles per liter (mmol/L) at screening, following a 12-hour fasting period.
• Fasting blood glucose assessed with a glucose meter above 5.5 mmol/L 0.5 hour before each dosing.
