NicOx SA Falls After Failing to Win FDA Panel's Backing Naproxcinod

Marketwire -- NicOx S.A. announced today that the Joint Advisory Committees of the U.S. Food and Drug Administration (FDA), including the Arthritis Drugs Advisory Committee and the Drug Safety and Risk Management Advisory Committee, voted by 16 to 1 with 1 abstention that they did not have sufficient evidence at this time to support the approval of naproxcinod for the relief of the signs and symptoms of osteoarthritis.

Chair Dr Kathleen O'Neil MD, Associate Professor of Pediatrics, University of Oklahoma College of Medicine, Division of Rheumatology, summarized the findings of the Advisory Committee meeting, saying there was enthusiasm for the potential of naproxcinod but more data was required from additional safety studies.

The FDA Arthritis Drugs Advisory Committee and Drug Safety and Risk Management Committee based their recommendation on a review of data from the naproxcinod clinical development program, which included 35 clinical studies involving more than 6,500 subjects. The New Drug Application (NDA) file contains data from three large pivotal phase 3 studies, all of which met their co-primary efficacy endpoints.

The FDA is not bound by the recommendations of the Advisory Committee but may take their advice into consideration when evaluating the NDA for naproxcinod. The FDA is expected to make a decision on whether to approve naproxcinod by July 24, 2010.

NicOx submitted a Marketing Authorization Application (MAA) for naproxcinod to the European Medicines Agency (EMA) in December 2009.

Conference calls on Thursday May 13

NicOx will hold a conference call in French on Thursday May 13 at 3:00 pm CET (9:00 am EST - 2:00 pm UK) and another one in English at 4:00 pm CET (10:00 am EST - 3:00 pm UK) to discuss the outcome of the Advisory Committee meeting. Details of these conference calls are available on the Company's website www.nicox.com.

About naproxcinod

Naproxcinod is NicOx's lead investigational compound and the first in a new class of anti-inflammatory agents known as CINODs (Cyclooxygenase- Inhibiting Nitric Oxide Donators). The NDA file is supported by data from a large program of 35 clinical trials that involved more than 6,500 subjects. The program evaluated the efficacy of naproxcinod in relieving signs and symptoms of osteoarthritis, as well as its safety, with particular care given to its effect on blood pressure.

In September 2009, NicOx submitted an NDA for naproxcinod, seeking approval for the relief of the signs and symptoms of osteoarthritis, which was accepted for filing by the FDA in November 2009. Based on the Prescription Drug User Fee Act (PDUFA), the FDA has set an action date of July 24, 2010. In December 2009, NicOx submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA), which was validated in January 2010.

About osteoarthritis

Osteoarthritis (OA), the most common type of arthritis, is a widespread degenerative disease which affects the joints and causes moderate to severe chronic pain. OA mainly occurs in the weight-bearing joints of the hips and knees and is associated with the breakdown of cartilage, a material which covers the ends of bones in normal joints. OA is most commonly seen in older people, especially women, and its exact cause is unknown, although heredity factors, previous joint damage and obesity appear to play a role. According to a Datamonitor estimate published in December 2009, OA is estimated to have afflicted over 81 million people in 2009 in the seven major markets (US, Japan, France, Germany, Italy, Spain and the UK), including approximately 29 million in the United States alone. Symptomatic treatments commonly used by OA patients include traditional non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 inhibitors.
