Semaglutide

GLP-1 receptor agonist studied in type 2 diabetes and obesity. One of the most investigated peptides of the past decade.

Approved

Overview

Semaglutide is a synthetic analogue of glucagon-like peptide-1 (GLP-1), an incretin hormone produced in the gut. Its fatty acid moiety allows reversible albumin binding, extending its half-life to roughly one week. The SUSTAIN (diabetes) and STEP (obesity) clinical programmes enrolled tens of thousands of participants.

Mechanism of action

Activates the GLP-1 receptor, stimulating glucose-dependent insulin secretion, reducing glucagon secretion, slowing gastric emptying and acting on appetite centres in the central nervous system.

Research areas

  • Type 2 diabetes
