Retatrutide

LY3437943

Also: Triple G

human trial

A triple agonist targeting GLP-1, GIP, and glucagon receptors simultaneously — the first 'triple G' therapy. In Phase 2 trials, Retatrutide produced up to 24% body weight loss at 48 weeks, the highest ever recorded for an anti-obesity drug. Currently in Phase 3 trials by Eli Lilly.

Simultaneously activates three receptors: GLP-1R (appetite suppression, insulin secretion), GIPR (potentiates GLP-1 effects, energy expenditure), and GCGR (glucagon receptor — increases energy expenditure, promotes fat oxidation, reduces hepatic steatosis). The triple mechanism explains superior efficacy.
