In September 2022, Eli Lilly published the results of its preclinical studies on LY3437943 in the journal Cell Metabolism, in an article titled "LY3437943, a novel triple glucagon, GIP, and GLP-1 receptor agonist for glycemic control and weight loss: From discovery to clinical proof of concept." In vitro and in vivo validation of the triple agonist effect of LY3437943: Eli Lilly's research results show that LY3437943 demonstrates superior weight loss effects compared to GLP-1 receptor (GLP-1R) selective agonists (GLP-1 RA), GLP-1R and GCGR dual agonists (Cotadutide or 05677), and GLP-1R and GIPR dual agonists
Nevertheless, their therapeutic potentials are still subject of debate, particularly given their known gastrointestinal side effects (e.g., nausea, vomiting, and diarrhea), which may limit their application in IBD patients, especially those with clinically active disease (14)
