Five-target drug beats GLP-1/GIP therapy in obese diabetic mice

A Nature study reports a single-molecule GLP-1–GIP–lanifibranor quintuple agonist that targets incretin receptor-expressing cells while activating PPARα/γ/δ pathways. In obese and insulin-resistant mice, the compound reduced body weight, food intake, and hyperglycaemia more effectively than semaglutide or GLP-1R–GIPR co-agonism, while remaining a preclinical finding.
