Glucagon-like Peptide-1 Receptor Agnoists for the Assessment of Adrenal Function - the PIANO Study

This study aims to investigate the effects of a single dose of the glucagon-like 1 receptor agonist semaglutdie/Rybelsus on the hypothalamo-pituitary-adrenal axis, thus cortisol levels and other stresshormones in healthy males.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in serum cortisol after Rybelsus vs. Placebo
Time Frame: within 210 minutes after the intake of the study drug
