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.

A single oral dose (50 mg tablet) of MK 0822 will be administered on Day 1 after an overnight fast.
Area Under the Concentration-time Curve of MK-0822 From Time 0 to Infinity (AUC0-∞) After Single Dose
For healthy and moderate hepatic insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of AUC0-∞ (Total AUC). AUC0-∞ is a measure of total drug exposure.
Time frame: Pre-dose and 1, 2, 4, 6, 9, 12, 16, 24, 32, 48, 72, 96, 120, 168, 240, and 336 hours postdose
Maximum Concentration (Cmax) of MK-0822 After Single Dose
For healthy and moderate hepatic insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of Cmax.
Time frame: Pre-dose and 1, 2, 4, 6, 9, 12, 16, 24, 32, 48, 72, 96, 120, 168, 240, and 336 hours postdose
Time to Maximum Concentration (Tmax) of MK-0822 After Single Dose
For healthy and moderate hepatic insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of Tmax.
Time frame: Pre-dose and 1, 2, 4, 6, 9, 12, 16, 24, 32, 48, 72, 96, 120, 168, 240, and 336 hours postdose
Apparent Terminal Half-life (t1/2) of MK-0822 After Single Dose
Apparent terminal half-life is the time required to divide the plasma (serum) concentration by two after reaching pseudo-equilibrium. (Note: it is not the time required to eliminate half the administered dose.) For healthy and moderate hepatic insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of t1/2. Results are presented using harmonic mean and jackknife standard deviation.
Time frame: Pre-dose and 1, 2, 4, 6, 9, 12, 16, 24, 32, 48, 72, 96, 120, 168, 240, and 336 hours postdose
