This study will investigate and compare pharmacokinetics of a single 50 mg dose of odanacatib administered to participants with impaired renal/kidney function to those of a healthy matched control group. The primary hypothesis is that plasma AUC0-∞ of odanacatib in participants with impaired renal function is similar to that in matched healthy participants following a single 50 mg oral dose.
