Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3, 53 Weeks Study on Analgesic Efficacy and Safety of Naproxcinod (HCT 3012): 26-Week, Randomized, Parallel-Group, Double-Blind, Placebo (13 Weeks)- and Naproxen (26 Weeks)-Controlled, Multicenter Study of Naproxcinod (375 mg Bid and 750 mg Bid) With a 26-Week Naproxen-Controlled Safety Follow-up in Subjects With Osteoarthritis of the Knee, and a 1-week Post-treatment Safety Follow-up

Further study details as provided by NicOx:

Primary Outcome Measures:
  • To show that both doses of Naproxcinod (375 mg twice daily [bid] and 750 mg bid) were superior to placebo in relieving osteoarthritis (OA) signs and symptoms in subjects with OA of the knee at Week 13. [ Time Frame: 13 weeks ]

Secondary Outcome Measures:
  • To assess the efficacy of naproxcinod compared to naproxen 500 mg bid in relieving OA signs and symptoms in subjects with OA of the knee [ Time Frame: 52 weeks ]
  • To evaluate the effect on blood pressure (BP) of both doses of naproxcinod, placebo, and naproxen 500 mg bid, as measured by the office BP monitoring in a population of OA subjects [ Time Frame: 52 weeks ]
  • To obtain information regarding the pharmacokinetics/exposure of both doses of naproxcinod through a population pharmacokinetics (PK) approach [ Time Frame: 52 weeks ]
  • To assess if there were any radiological changes at Week 52 in naproxcinod compared with naproxen subjects (target joint radiographs were taken at Screening and after 52 weeks of treatment, or if early termination occurred after Week 26) [ Time Frame: 52 weeks ]
  • To compare the general safety and tolerability of both doses of naproxcinod versus naproxen 500 mg bid up to 52 weeks and with one Week post treatment follow up (Week 53) [ Time Frame: 53 weeks ]

Detailed Description:
This is a 53 week study consisting in a 26 week randomized, double-blind, parallel group, multicenter study comparing efficacy and safety of Naproxcinod, Placebo and Naproxen. The first 26 weeks will be followed by a naproxen-controlled treatment period up to 52 weeks and a 1-week post-treatment safety follow-up.
