Retatrutide
Triple-receptor agonist (GIP/GLP-1/glucagon) at the research frontier.
Retatrutide
Background
Retatrutide (development code LY3437943) is an investigational single-molecule triple agonist targeting the GIP, GLP-1, and glucagon receptors. The addition of glucagon-receptor agonism to dual incretin activity is hypothesized to increase energy expenditure alongside appetite suppression, an approach studied in metabolic and obesity research.
Phase 2 trials reported dose-dependent reductions in body weight and HbA1c. As an investigational agent, retatrutide has not completed phase 3 development and is not approved for any use.
