The approvals of semaglutide and tirzepatide have set new benchmarks in the treatment of type 2 diabetes and obesity. Building on their success, novel glucagon-like peptide-1 (GLP-1)-based therapeutics are rapidly advancing. These next-generation agents engage not only GLP-1 receptors but also those for other gastro-entero-pancreatic hormones such as glucose-dependent insulinotropic polypeptide (GIP), glucagon, amylin, and peptide YY to enhance energy uptake, storage, and expenditure through synergistic mechanisms. Both GIP receptor agonism and antagonism, particularly in combination with GLP-1 receptor agonism, have shown promise. Maridebart cafraglutide, combining GLP-1 receptor agonism with GIP receptor antagonism, exemplifies this innovative approach. Glucagon coagonists like survodutide and mazdutide have demonstrated significant weight loss and improved glycemic control. Amylin-based agents, including CagriSema (cagrilintide + semaglutide) and amycretin, enhance satiety and glycemic outcomes through complementary actions. Further innovation is seen in triple agonists such as retatrutide, which targets GIP, GLP-1, and glucagon receptors to amplify metabolic effects. Meanwhile, the emergence of orally active small-molecule GLP-1 receptor agonists like danuglipron and orforglipron, which are resistant to enzymatic degradation, marks a major advance in patient-friendly drug delivery. This review explores the mechanisms, clinical development, and therapeutic potential of the...
