A Single Dose Study of the Pharmacokinetics of Vibegron (MK-4618) in Participants With Renal Insufficiency (MK-4618-014)

This study will investigate the impact of impaired renal function on the plasma pharmacokinetics of vibegron (MK-4618) to guide use of vibegron in clinical trials in participants with overactive bladder and to guide recommendations on potential dosing adjustments for individuals with varying degrees of renal impairment.
