A new molecule combines the action of two incretins, GLP-1 and GIP, hormones that regulate glucose and appetite, with lanifibranor, a triple agonist of peroxisome proliferator activated receptors (PPAR α/γ/δ). GLP-1-GIP-Lani enables targeted delivery of the PPAR agonist to cells that express incretin receptors, enhancing weight loss, improving glucose control and reducing inflammation in obese mice. In these models, it surpassed the effects of GLP-1 receptor agonists such as semaglutide and GLP-1-GIP co-agonists such as tirzepatide in reducing body weight, improving glycemic control and enhancing metabolic outcomes during active treatment.
