Conditions

Overactive Bladder

Brief summary

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.

Outcome results

Primary

Apparent Total Body Clearance (CL/F) After a Single Oral Dose of Vibegron 100 mg

Blood samples were collected predose and at 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 120, 216, and 336 hours after dosing in order to determine CL/F after a single oral dose of vibegron 100 mg.

Time frame: Predose and 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 120, 216, and 336 hours postdose

Population: PP population, which included participants who complied with the protocol sufficiently to ensure that the data were likely to exhibit the effects of treatment, according to the underlying scientific model.
