Description: Vibegron, also known as MK-4618, is a potent and selective Beta 3 Adrenergic Receptor Agonist for the Treatment of Overactive Bladder (OAB). Vibegron has no unacceptable toxicity in preclinical species. Vibegron is currently in Phase 3 human clinical trials for the treatment of OAB. β3-adrenergic receptor (β3-AR) agonists were investigated as potential treatments for obesity and/or diabetes owing to their ability to induce lipolysis, thermogenesis, and antihyperglycemic activity in preclinical species.
