Survodutide (BI 456906) is a novel dual agonist targeting both the glucagon and GLP-1 receptors, developed for obesity treatment. Structurally based on glucagon and modified with a C18 fatty diacid for weekly dosing, it stimulates lipolysis and energy expenditure via the glucagon receptor while reducing appetite and gastric emptying through the GLP-1 pathway. In phase 2 trials, survodutide led to greater weight loss than semaglutide, with reductions up to −14.1% over 16 weeks. Doses ≥2.4 mg induced significant bodyweight loss in over 50% of participants, showing sustained results through 46 weeks.
