[From GLP1 receptor agonists to triple hormone receptor activation supplemented with glucagon receptor agonism.]

Following the introduction of mono- and then dual hormone (incretin) receptor agonists into therapy, attention was turned to multiple receptor stimulation, with the additional activation of the glucagon receptor, as a new option for the pharmaceutical treatment of type 2 diabetes and obesity. In addition to its role in carbohydrate metabolism, the article reviews the other important physiological tasks of glucagon, especially its participation in intrainsular paracrine regulation, energy expenditure and the shaping of appetite and food consumption. It covers the potential benefits of the triple combination and briefly touches data on the efficacy and safety of the first triple receptor agonist drug, retatrutide, in preclinical human studies. Further confirmation of the promising results may represent progress in the treatment of these forms of disease and their accompanying conditions, such as steatosis hepatis.

New Frontiers in Obesity Treatment: GLP-1 and Nascent Nutrient-Stimulated Hormone-Based Therapeutics

Nearly half of Americans are projected to have obesity by 2030, underscoring the pressing need for effective treatments. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) represent the first agents in a rapidly evolving, highly promising landscape of nascent hormone-based obesity therapeutics. With the understanding of the neurobiology of obesity rapidly expanding, these emerging entero-endocrine and endo-pancreatic agents combined or coformulated with GLP-1 RAs herald a new era of targeted, mechanism-based treatment of obesity. This article reviews GLP-1 RAs in the treatment of obesity and previews the imminent future of nutrient-stimulated hormone-based anti-obesity therapeutics.
