Brief Summary
Patients with renal impairment are the target population for PF-04634817. The clearance mechanism of this drug means that exposure may be increased in subjects with renal impairment. This study will investigate the effect of the drug in subjects with varying degrees of renal impairment. Pharmacokinetics, safety and toleration will be assessed.

Outcome Measures
Primary Outcomes (8)
Area Under the Curve From Time Zero to 48 Hours[AUC (0 - 48)]
AUC (0 - 48)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to 48hours.
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast).
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - Inf)]
AUC (0 - inf)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time.
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Apparent Oral Clearance (CL/F)
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population PK modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Maximum Observed Plasma Concentration (Cmax)
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Apparent Volume of Distribution (Vz/F)
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
Plasma Decay Half-Life (t1/2)
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, 24, 32, 40, 48, 56, 64, 72, 84, 96, 108, 120, 132, 144, 156, 216, 312 hours post dose
