Clinical Trial 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.


Description:

1. To compare the effect of prolonged hyperglucagonemia to that of acute hyperglucagonemia on energy expenditure in healthy subjects using room indirect calorimetry in the setting of octreotide-mediated prevention of plasma insulin excursions.

2. To compare the effects of prolonged hyperglucagonemia to acute hyperglucagonemia on EGP in healthy subjects in the setting of octreotide-mediated prevention of plasma insulin excursions.

3. To determine the effects of prolonged hyperglucagonemia to acute hyperglucagonemia on rates of substrate oxidation, fibroblast growth factor21 and metabolites of interest.

- is unwilling or unable to adhere to the dietary needs during the study, or to consume the standardized meals during the study, and/or is on a carbohydrate restricted diet (i.e., a diet <100 grams per day of carbohydrate).

- is any concern by the investigator regarding the safe participation of the subject in the trial or for any other reason; the investigator considers the subject inappropriate for participation in the trial.

- has a history of claustrophobia or is claustrophobic.

- has ever had an organ transplant.

- is a smoker or uses other nicotine-containing products (for at least 6 months prior to drug administration); plans to begin smoking or using nicotine-containing products during the conduct of the study.

- has poor intravenous access.

- has used any medications that are known to influence glucose, fat, or energy metabolism within the last 3 months (growth hormones, steroids, etc.)

- has blood pressure at screening visit less than or equal to 100/50 mm Hg or greater than or equal to 160/100 mm Hg.

Outcome

Type Measure Description Time frame Safety issue
Primary Measure of energy expenditure Energy expenditure (and respiratory quotient) will be measured within the small calorimeter rooms. Oxygen and carbon dioxide levels in the chambers will be measured. Day 2, Day 9, Day 16
