NicOx Provides Update on U.S. Regulatory Status of Naproxcinod

April 4, 2012. Sophia Antipolis, France. - NicOx S.A. today announces that it met with the United States Food and Drug Administration (FDA) on April 3, 2012, to discuss the proposed use of naproxcinod 375 mg twice daily (bid), for the treatment of signs and symptoms of osteoarthritis (OA) of the knee, under a proposed new NDA (New Drug Application) that would require additional clinical data prior to any such NDA submission.

The subject of the April 3, 2012 meeting was the required clinical data for the potential new NDA for naproxcinod 375 mg bid.

NicOx will assess the requirements for further clinical data discussed with the FDA and its impact on the overall development program of naproxcinod. NicOx intends to seek a partner to fund and manage any further development and potential commercialization of naproxcinod.

NicOx had previously submitted an NDA for naproxcinod 375 mg bid and 750 mg bid for the treatment of signs and symptoms of OA not limited to the knee. NicOx received a Complete Response Letter in July 2010 stating that the FDA did not approve that naproxcinod NDA. NicOx initiated a Formal Dispute Resolution process in July 2011 regarding that decision involving the previously submitted NDA. These were not the topic of the April 3, 2012 meeting.

NicOx is focused on becoming an international, late-stage development and commercial ophthalmology company in therapeutics, diagnostics and devices. NicOx intends to build a diversified, late-stage ophthalmology portfolio with a clear route to commercialization. The Company is currently evaluating a number of additional ophthalmic acquisition and in-licensing opportunities both in the United States and in Europe.
