Further study details as provided by VU University Medical Center:

Primary Outcome Measures:
  • To assess whether a single day infusion of the GLP-1 RA exenatide, as compared to placebo, reverses GC-induced impairment of glucose metabolism in healthy males, quantified as glucose tolerance (AUCgluc) during a standardized mixed-meal test [ Time Frame: Single-day treatment ]

Secondary Outcome Measures:
  • To assess whether a single day infusion of the GLP-1 RA exenatide, as compared to placebo, reverses GC-induced acute beta-cell dysfunction in healthy males, quantified as Various measures of beta-cell function [ Time Frame: Single day treatment ]

Estimated Enrollment: 8
