Investigating the effects of a glucagon-like peptide-1 receptor agonist on adrenal function in healthy males

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

Not applicable Interventional University Hospital, Basel, Switzerland · NCT06608433

This study is testing how a single dose of a diabetes drug called semaglutide affects stress hormones in healthy men aged 18-60.

What this trial studies

This study examines how a single dose of the glucagon-like peptide-1 receptor agonist semaglutide affects the hypothalamo-pituitary-adrenal axis and cortisol levels in healthy male volunteers. Participants will receive either semaglutide or a placebo to assess the drug's impact on stress hormones. The study focuses on understanding adrenal function and its regulation in response to this medication. Healthy males aged 18-60 with a specific BMI range will be recruited for this investigation.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy male volunteers aged 18-60 years with a BMI between 18.5 and 30 kg/m2.

Not a fit: Patients with a history of glucocorticoid or GLP-1 receptor agonist intake in the last 8 weeks or those with known allergies to GLP-1 receptor agonists may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of adrenal function and improve treatment strategies for conditions related to cortisol deficiency.

How similar studies have performed: While the specific approach of using semaglutide in this context may be novel, similar studies have explored the effects of glucagon-like peptide-1 receptor agonists on various physiological processes.
