Pharmacokinetic Assessment of Single-Dose Odanacatib (MK-0822) in Subjects With Severe Renal Insufficiency (MK-0822-067)

Study Overview
=================
Brief Summary
-----------------
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.

Inclusion Criterion Specific to Participants with Renal/Kidney Insufficiency: Creatinine clearance of <30 mL/min Inclusion Criterion Specific to Healthy Volunteers: Creatine clearance of ≥ 90 mL/min (for healthy volunteers) Exclusion Criteria: Does not meet the age requirement, is mentally or legally incapacitated, has or is expected to have significant emotional problems, and/or a history of a clinically significant psychiatric disorder. Diagnosed with a disease or medical condition which may pose a risk to the participant or may confound the study results. Has demonstrated or suspected stenosis (narrowing) of the renal artery, and/or has had a renal transplant and/or kidney removal. Has current, unstable, significant organ system disease(s) and/or cancer(s). Has had a surgical procedure, donated 1 unit of blood or received another investigational study medication within 4 weeks prior to the study's first dose of investigational product. Unable to refrain from or anticipates the use of any new medication, including prescription and non-prescription drugs and/or herbal remedies. Exceptions may include medications prescribed for prevention of disease or preservation of a healthy life. Uses any medication or agent that has the potential to significantly alter renal/kidney function. Unable to avoid taking diuretics (within 4 hours prior to and after dosing with the investigational product) or phosphate binders containing aluminum, calcium or lanthanum salts; iron supplements or other metal cations; antacids; or multivitamins containing iron or zinc (within 8 hours prior to dosing and 4 hours after dosing with the investigational product). Note: individuals prescribed to diuretics must be on a stable dose for at least 4 weeks prior to the study's start date in order to participate. History of multiple and/or severe allergies, has had a life-threatening reaction to a drug or other agent, and/or inability to tolerate prescription or nonprescription drugs and/or food.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Concentration-time Curve of MK-0822 From Time 0 to Infinity (AUC0-∞) After Single Dose | For healthy and severe renal 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. | Pre-dose and 1, 2, 4, 6, 9, 12, 16, 24, 32, 48, 72, 96, 120, 168, 240, and 336 hours postdose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Concentration (Cmax) of MK-0822 After Single Dose | For healthy and severe renal insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of Cmax. | 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 severe renal insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of Tmax. | 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 | For healthy and severe renal insufficiency participants, plasma samples were collected from predose to 336 hours postdose for determination of t1/2. | Pre-dose and 1, 2, 4, 6, 9, 12, 16, 24, 32, 48, 72, 96, 120, 168, 240, and 336 hours postdose |
