Pharmacokinetics of MK4305 in Participants With Impaired Renal Function (MK-4305-023)(COMPLETED)
An Open-Label, Single-Dose Study to Investigate the Pharmacokinetics of MK4305 in Patients With Impaired Renal Function

This study will investigate whether the plasma concentration-time profile and pharmacokinetics of MK-4305 in participants with impaired renal function are similar to those observed in healthy participants; and will evaluate the safety and tolerability of MK-4305 both in participants with impaired renal function and in healthy participants.

If preliminary data from Part I confirms that renal impairment does not alter the pharmacokinetics of MK-4305 to the extent that would require a dosage adjustment, then no further study will be required. If the data does not support this conclusion, then Part II will be conducted.
