Brief Summary
The purpose of this study is to collect data to help researchers better understand the effects of glucagon on the amount of calories burned.
Detailed Description

- has a clinically significant abnormality on screening ECG or evidence or a history of myocardial ischemia, atrioventricular block, Wolf-Parkinson-White syndrome or other conduction abnormality. Subjects having any clinically significant ECG abnormality at screening may be included at the discretion of the PI.
- has a fasting blood glucose (FPG) less than or equal to 65 mg/dL or greater than or equal to 100 mg/dL on the pre-study screening labs.
- has impaired kidney or liver function, as evidenced by screening blood work.
- has irritable bowel disease, or recurrent occurrences of nausea, vomiting, diarrhea, constipation or abdominal pain.
- has a history of any illness that, in the opinion of the study investigator, might confound the results of the study or poses an additional risk to the subject by their participation in the study.
- has an estimated creatinine clearance of ≤80 mL/min based on the Cockcroft-Gault equation
- has a history of neoplastic disease
- has a history of significant multiple and/or severe allergies (e.g. food, drug, latex allergy), or has had an anaphylactic reaction or significant intolerability to prescription or non-prescription drugs or food; or allergy/intolerability to insulin, glucagon, or octreotide.
- is positive for hepatitis B surface antigen, hepatitis C antibodies, or HIV
- had major surgery within 3 months, donated or lost 1 unit of blood (approximately 500 mL) within 4 weeks prior to the pretrial (screening) visit.
- has participated in another investigational trial within 4 weeks prior to the pretrial (screening) visit. The 4 week window will be derived from the date of the last trial medication and / or blood collection in a previous trial and/or adverse event related to trial drug to the pretrial/screening visit of the current trial.
