Study Endpoints
Primary Endpoints
Maximum Observed Plasma Concentration (Cmax) of CP-70429 Following CP-70,429 Intravenous Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)

PF-03709270 is an oral prodrug of CP-70,429. Upon oral absorption, PF-03709270 is rapidly hydrolyzed, yielding the active drug CP-70,429. Cmax of CP-70429 following CP-70,429 intravenous dose was reported.

Time to Reach Maximum Observed Plasma Concentration (Tmax) of CP-70429 Following CP-70,429 Intravenous Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of CP-70429 Following CP-70,429 Intravenous Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)

Area under the plasma concentration time-curve from zero (pre-dose) to the time of last measured concentration (AUClast).

Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-inf)] of CP-70,429 Following CP-70,429 Intravenous Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)

AUC (0-inf) is the area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). It is obtained from AUC (0-t) plus AUC (t-inf).

Renal Clearance (CLr) of CP-70429 Following CP-70,429 Intravenous Dose
0 (pre-dose), 0 to 6, 6 to 12, 12 to 24 hours post-dose

Renal clearance was calculated as cumulative amount of drug recovered unchanged in urine during the dosing interval (Ae) divided by area under the plasma concentration time-curve from time zero to end of dosing interval (AUCtau).

Maximum Observed Plasma Concentration (Cmax) of CP-70429 Following PF-03709270 Oral Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)

PF-03709270 is an oral prodrug of CP-70,429. Upon oral absorption, PF-03709270 is rapidly hydrolyzed, yielding the active drug CP-70,429. Cmax of CP-70429 following CP-70,429 intravenous dose was reported.

Time to Reach Maximum Observed Plasma Concentration (Tmax) of CP-70429 Following PF-03709270 Oral Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of CP-70429 Following PF-03709270 Oral Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)

Area under the plasma concentration time-curve from zero (pre-dose) to the time of last measured concentration (AUClast).

Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-inf)] of CP-70429 Following PF-03709270 Oral Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)

AUC (0-inf) is the area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). It is obtained from AUC (0-t) plus AUC (t-inf).

Renal Clearance (CLr) of CP-70429 Following PF-03709270 Oral Dose
0 (pre-dose), 0 to 6, 6 to 12, 12 to 24 hours post-dose

Renal clearance was calculated as cumulative amount of drug recovered unchanged in urine during the dosing interval (Ae) divided by area under the plasma concentration time-curve from time zero to end of dosing interval (AUCtau).

Secondary Endpoints
Terminal Elimination Half Life (t1/2) of CP-70429 Following CP-70,429 Intravenous Dose
0 (pre-dose), 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24 hours post-dose (for all participants) and 48 hours post-dose (for participants with moderate and severe renal impairment)
Terminal Elimination Half Life (t1/2) of CP-70429 Following PF-03709270 Oral Dose
