Assessment of Pharmacokinetics of Single Dose Odanacatib (MK-0822) in Participants With Moderate Hepatic Insufficiency (MK-0822-070)

Single Dose Study to Investigate the Pharmacokinetics of Odanacatib (MK-0822) in Subjects With Hepatic Insufficiency

This open-label, non-randomized study was designed to compare pharmacokinetics of a single 50 milligram (mg) dose of MK-0822 in participants with and without moderate hepatic insufficiency (abnormal liver function) in order to determine to what degree hepatic dysfunction may impact therapeutic blood levels of MK-0822. The primary hypothesis is that plasma AUC0-∞ of odanacatib in participants with moderate hepatic insufficiency is similar to that in matched healthy participants following a single 50 mg oral dose.
