Zusammenfassung
Gastrointestinale Hormone nehmen eine wichtige Rolle in der endokrinen Kommunikation zwischen Darm, Pankreas, Leber und Gehirn ein. Glucagon-like-peptide-1-Rezeptor-Agonisten (GLP-1RA) sind als Therapeutika bei Diabetes mellitus Typ 2 mittlerweile fest etabliert. Eine pharmakologische Weiterentwicklung sind die multiplen Agonisten, die als Liganden an mehreren Darmhormonrezeptoren fungieren. Zielstrukturen für die Wirkung sind hier neben „glucagon-like peptide 1“ (GLP-1) die Rezeptoren von „glucose-dependent insulinotropic polypeptide“ (GIP) und Glukagon. Durch die multiple Agonistenwirkung sollen glykämische Wirkungen und Effekte auf das Körpergewicht verstärkt werden. Der vorliegende Beitrag gibt eine Übersicht über GLP-1RA und die multiplen Agonisten. Unter den dualen Agonisten hat der GIP/GLP-1-Agonist Tirzepatid mittlerweile eine Zulassung zur Behandlung des Typ-2-Diabetes. Klinische Zulassungsstudien zum Einsatz von Tirzepatid bei Adipositas werden derzeit durchgeführt. Die aktuellen Daten aus Studien zu GLP-1/Glukagon-Agonisten und Dreifachagonisten werden hier ebenfalls zusammengefasst.
Abstract
Gastrointestinal hormones play an important role in the endocrine communication between the intestine, the pancreas, the liver and the brain. Glucagon-like peptide‑1 receptor agonists (GLP-1RA) are established therapeutic agents in the treatment of type‑2 diabetes. Multiple agonists acting as ligands on various gastrointestinal hormone receptors are a novel pharmacological development. In addition to glucagon-like peptide 1 (GLP-1), these multiple agonists also have glucose-dependent insulinotropic polypeptide (GIP) and/or glucagon receptors as target structures for their pharmacological action. The multiple agonist action is designed to increase glycaemic effects as well as the effects on body weight. This article provides an overview of GLP-1RA and the multiple agonists. Among the dual agonists, the GIP/GLP-1-agonist tirzeptide has been approved for the treatment of type‑2 diabetes, and clinical studies with tirzepatide as a treatment for obesity are ongoing. The currently available data on studies with GLP-1/glucagon agonists and triple agonists are also summarized.
