Effects of Single-dose Semaglutide on Cognition and Energy in Healthy Volunteers

University of Oxford·interventional·Posted Apr 12, 2024·Updated Jun 6, 2025

In Brief

A clinical study evaluating Semaglutide, 0.5 mg/mL and Placebo, 0.9% NaCl 1.5mL for Cognitive Change. Completed, enrolled 70 participants across 1 site.

Detailed Summary

Semaglutide is a glucagon-like peptide 1 receptor agonist (GLP-1RA). It is a safe medication approved for use in type-2 diabetes mellitus (T2DM) and obesity. Primarily, it works by counteracting insulin-resistance and inducing weight loss. It also acts on several other interconnected neurobiological, immunological (esp. inflammatory), endocrine-metabolic, and gut-brain axis processes that play a role in depressive symptoms. Its effects on cognition and energy are currently unknown. In this study we are using semaglutide as an experimental tool to further investigate these relationships.

Interventions

Semaglutide, 0.5 mg/mLdrug

Injected subcutaneously (pre-filled pen) in the upper arm (preferred site), in the abdomen, or in the thigh according to participant's preference. The participant will be asked to wear an eye blindfold during the time of the study medication/placebo administration, to avoid compromising blinding. It is not possible to blind the researcher administering the medication/placebo because semaglutide comes in specific pre-filled pens. The person who administers the subcutaneous injection will be suitably trained and experienced, and have been authorised to do so by the Principal Investigator - they will not be involved in other aspects of the study for that participant to avoid compromising blinding.
