Effect of Repeated Administration of Liraglutide on Insulinogenic Indices

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02089256
Recruitment Status : Completed

Brief Summary:
The study investigates the effect of glucagon-like peptide receptor 1 agonist, liraglutide, on insulin secretion. Study hypothesis: the effect of liraglutide on insulin release may change after repeated administration. The effect of liraglutide on insulin release will be tested using graded glucose infusion test (GGIT) in healthy volunteers. GGIT will be performed without medication and repeated 12 hours after first dose of liraglutide and after 3 weeks of treatment with liraglutide.

Drug Information available for: Liraglutide

Arm Intervention/treatment
Experimental: Liraglutide
Liraglutide 0.6 mg/day subcutaneously.
Drug: Liraglutide

Graded glucose infusion test (GGIT)will be performed on baseline. 1 week later treatment with liraglutide 0.6mg/day (injected between 21.00-23.00) will be initiated.

GGIT will be repeated 12 hours after first injection and after 21 days on-treatment (12 hours after last injection).

Other Name: Victoza

Primary Outcome Measures :
  1. Change in the glucose-sensitivity of the beta cells [ Time Frame: baseline, first dose, after 3-weeks on treatment ]
    Graded glucose infusion test will be used to create insulin secretion rate- plasma glucose curve. The primary outcome is the change of the slope of the curve from baseline after acute administration of liraglutide compared to the repeated administration (after 3-weeks of treatment).

Secondary Outcome Measures :
  1. Effects on adrenal hormones [ Time Frame: baseline, acute administration, 3 weeks ]
    change in ACTH/cortisol levels and renin / aldosterone levels after acute and repeated administration of liraglutide.
