Retatrutide (compound code LY3437943) is an investigational 39-amino-acid peptide that acts as a triple agonist at the GLP-1, GIP, and glucagon receptors. It is the first compound of its class to advance into Phase 3 clinical research for obesity and type 2 diabetes.
Simultaneously activates three incretin-related receptors: GLP-1 (glucose-dependent insulin release + satiety), GIP (insulin secretion + adipose function), and glucagon (hepatic energy expenditure). Published studies describe additive effects on energy expenditure versus GLP-1 monotherapy.
Developed by Eli Lilly. Phase 2 results published in NEJM (2023) reported 24.2% mean body-weight reduction at 48 weeks with the 12 mg dose. Continues in comparative metabolic research.
