NicOx S.A. (NYSE Euronext Paris: COX) today announced that several scientific posters on naproxcinod results were presented yesterday at the European League Against Rheumatism (EULAR) Congress in Copenhagen, Denmark. Naproxcinod is an investigational drug and the first-in-class Cyclooxygenase-Inhibiting Nitric Oxide Donating (CINOD) anti-inflammatory agent, which is in preparation for regulatory submissions in the US and Europe for the relief of signs and symptoms of osteoarthritis (OA). The poster presentations included the following data:

- Efficacy results from the second pivotal phase 3 trial (the 302 study) were presented in a poster entitled 'A Randomized, Parallel Group, Double Blind, Placebo and Naproxen Controlled, Multicenter Phase 3 Study of Naproxcinod in Subjects with Osteoarthritis of the Knee: Efficacy Results Following 13-Week Treatment' (poster number THU0341). For more details on the 302 study design and results, see the NicOx press release of September 15, 2008.

- Utility and quality of life results from the three pivotal phase 3 trials (the 301, 302 and 303 studies) were presented in a poster entitled 'Utility and Quality of Life of Patients with Osteoarthritis Treated with a Cyclooxygenase Inhibiting Nitric Oxide Donator (CINOD), Naproxcinod' (poster number THU0543-AHP). For more details on the utility and quality of life analyses conducted on data from the 301 trial, see the NicOx press release of May 19, 2009.
