Study Endpoints

Primary Endpoints

Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Domain Score at Week 2
Baseline, Week 2

WOMAC: self-administered, disease-specific 24 item questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness, and physical function in participants with osteoarthritis (OA) of the hip and/or knee. It consists of 3 domains: pain, stiffness and physical function. WOMAC pain domain consists of 5 questions scored on 5 point Likert scale (0=minimum pain to 4=maximum pain) where higher score indicates higher pain. It assesses amount of pain experienced due to OA in the study joint in past 48 hours. Total possible pain domain score calculated by addition of scores of each 5 questions ranged from: 0 (minimum) - 20 (maximum), higher scores indicate higher pain.

Area Under the Curve from time Zero to Extrapolated Infinite Time (AUC[0-inf]).
0(pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours (hrs) post-PF-04136309 dose

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

Maximum Plasma Concentration [Cmax]
0(pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hrs post PF-04136309 dose
