A Phase 2 Randomized, Double-Blinded, Double-Dummy, Placebo And Active Controlled Two Cohort Two-Way Cross-Over, Multi-Centre Clinical Trial To Examine The Pain Relief Produced By 2 Weeks Of Daily Oral Administration Of A 5-Lipoxygenase (5-Lox) Inhibitor PF-04191834 Alone And In Combination With Naproxen In Patients With Flare-Enriched Osteoarthritis Of The Knee

ClinicalTrials.gov · TERMINATED, 2011

Abstract

PF-04191834 works in animal models by inhibiting one of the enzymes, 5-lipoxygenasein which is involved in the pathway that causes inflammation and pain. The purpose of this study is to test how effective, safe and tolerated PF-04191834 is in patients with osteoarthritis of the knee by itself or with naproxen, particularly to test if patients have less pain.

Conditions: Osteoarthritis, Knee.

Primary outcome: Change From Baseline in Western Ontario & McMaster (WOMAC) Osteoarthritis Index Pain Score at the End of Treatment Period 1; Change From Baseline in Western Ontario & McMaster (WOMAC) Osteoarthritis Index Pain Score at the End of Treatment Period 2.

Enrollment: 190 participants.
