Primary Outcome Measures:
  • The primary objective of this study is to show that naproxcinod is superior to placebo in relieving OA signs and symptoms in subjects with OA of the knee at 13 weeks and to collect long term safety data [ Time Frame: 13 weeks / long term ]

Enrollment: 918
Study Start Date: December 2005
Study Completion Date: September 2007
Arms Assigned Interventions
Placebo Comparator: Placebo bid
At 13 weeks, the patients receiving placebo were re-randomized to receive either naproxcinod 375 mg bid or naproxcinod 750 mg bid in a 1:1 ratio in the 301E study.
Drug: Placebo
At 13 weeks, the patients receiving placebo were re-randomized to receive either naproxcinod 375 mg bid or naproxcinod 750 mg bid in a 1:1 ratio in the 301E study.
Experimental: Naproxcinod 375 mg bid Drug: Naproxcinod 375 mg
Active Comparator: Naproxen 500 mg bid Drug: Naproxen
Experimental: Naproxcinod 750 mg bid Drug: Naproxcinod 750 mg

Detailed Description:

This is a 13-week double-blind study followed by a 52-week, open-label, roll-over on active treatment study. These are randomized, parallel group, multicenter studies comparing efficacy and safety of naproxcinod, placebo and naproxen.
