Study Endpoints

Primary Endpoints

Standard safety assessments including assessment of AEs, laboratory tests, ECGs, and vital signs.
Screening, Dosing days 1-10, through follow-up
The primary pharmacokinetic endpoints to be evaluated for PF-04287881 include Cmax, Tmax, and AUC(0-24) on Day 1 and Day 10.
Day 1 and 10
Evaluation of safety and tolerability of PF-04287881 after single oral dose.
Daily up to discharge, follow-up 7-10 days after dosing

Secondary Endpoints

Secondary parameters include AUCinf and t1/2 as data permit, apparent oral clearance (CL/F), apparent volume of distribution (Vz/F) and accumulation ratio (Rac).
Days 1, 5 and 10
Urine concentrations of PF 04287881 in Cohorts 2 and 5 will be used to determine total amount excreted (Ae), %Ae relative to dose given and renal clearance (CLR).
Day 10
Concentrations of PF 04287881 will be measured in white blood cell (WBC) polymorphonuclear cells (PMNs) in Cohorts 2 and 5 to determine total exposure in WBC.
