NicOx S.A. (NYSE Euronext Paris: COX) today announced the receipt of a Complete Response Letter from the U.S. Food and Drug Administration (FDA) related to the New Drug Application (NDA) for naproxcinod. Naproxcinod is being developed for the relief of the signs and symptoms of osteoarthritis.

The FDA informed NicOx that its review of the NDA is complete and that it does not approve the naproxcinod application. The FDA has recommended conducting one or more long-term controlled studies to assess the cardiovascular and gastrointestinal safety of naproxcinod. Additional studies to demonstrate a clinically meaningful therapeutic benefit attributable to the nitric oxide donation were also recommended. No clinical efficacy studies were requested.

NicOx plans to discuss the Complete Response Letter and potential next steps as early as possible with the FDA.

The naproxcinod Marketing Authorization Application (MAA) submitted by NicOx in December 2009 is currently under review by the European Medicines Agency (EMA).

NicOx remains well funded and had cash, cash equivalents and financial instruments of EUR 138.5 million at the end of March 2010.
