SOPHIA ANTIPOLIS, FRANCE--(Marketwire - June 21, 2010) - www.nicox.com

NicOx S.A. (NYSE Euronext Paris: COX) today announced that additional naproxcinod clinical data were presented at the Annual European Congress of Rheumatology, the annual conference of the European League Against Rheumatism (EULAR), which took place from June 16 to June 19 in Rome, Italy. Two posters on clinical results for naproxcinod were presented. The abstracts are available on the congress website (www.eular.org/congress_home.cfm).

Naproxcinod is the first-in-class CINOD (Cyclooxygenase-Inhibiting Nitric Oxide-Donating) anti-inflammatory drug-candidate developed for the relief of the signs and symptoms of osteoarthritis. It is currently under review by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA).

Risks factors which are likely to have a material effect on NicOx's business are presented in the 4th chapter of the " Document de référence, rapport financier annuel et rapport de gestion 2009 " filed with the French Autorité des Marchés Financiers (AMF) on March 5, 2010 and available on NicOx's website (www.nicox.com) and on the AMF's website (www.amf-france.org).

The Company notably draws the investors' attention to the following risk factors:

- Risques liés à la dépendance de la Société à l'égard du naproxcinod (Risks related to the Company's dependence on the success of its lead product naproxcinod)

- Risques commerciaux et développements cliniques (Clinical developments and commercial risk)

- Risques liés aux contraintes réglementaires et à la lenteur des procédures d'approbation (Risks linked to regulatory constraints and slow approval procedures)

- Manque de capacités dans les domaines de la vente et du marketing (Lack of sales and marketing capabilities)

- Incertitude relative aux prix des médicaments et aux régimes de remboursement, ainsi qu'en matière de réforme des régimes d'assurance maladie (Uncertainty on drug pricing and reimbursement policies and on the reforms of the health insurance systems)

NicOx's lead investigational compound is naproxcinod, an NME and a first- in-class CINOD (Cyclooxygenase-Inhibiting Nitric Oxide-Donating) anti- inflammatory drug candidate developed for the relief of the signs and symptoms of osteoarthritis (OA), which is currently under review by regulatory authorities, following the submission and filing of a New Drug Application (NDA) to the US Food and Drug Administration (FDA) and a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA). The FDA and the EMA are evaluating the data submitted. The FDA has set an action date of July 24, 2010, under the Prescription Drug User Fee Act (PDUFA).
