| Clinical Status | Phase 3 clinical trials (Eli Lilly TRIUMPH program) | Phase 3 (REDEFINE program). NDA filed with FDA in 2026 for CagriSema. |
| Mechanism | Retatrutide simultaneously activates three receptors: GLP-1 (reduces appetite, slows gastric emptying, improves insulin secretion), GIP (enhances insulin sensitivity, glucose control), and glucagon (increases energy expenditure, fat oxidation, thermogenesis). This triple synergy combines reduced cal... | Cagrilintide activates amylin receptors (calcitonin receptor + RAMP complexes) in the area postrema and other hindbrain regions, promoting meal-related satiety through distinct pathways from GLP-1 agonism. It slows gastric emptying, suppresses inappropriate glucagon release, and activates central ap... |
