Notes to editors

About laquinimod and MS Laquinimod is a novel once-daily, orally administered immunomodulatory compound developed as a disease modifying treatment for multiple sclerosis (MS). Active Biotech developed laquinimod and licensed it to Teva Pharmaceutical Industries, Ltd. in June 2004. Currently, laquinimod is in Phase III global clinical trials encompassing a total of 2,200 patients at 175 sites. MS is the leading cause of neurological disability in young adults. It is estimated that two million people are affected worldwide. MS is a progressive, demyelinating disease of the central nervous system, affecting the brain, spinal cord and optic nerves. Demyelination is the destructive breakdown of the fatty tissue that protects nerve endings. Initially, MS comes in "flare-ups," with alternating periods of deterioration and stability. The disease mainly affects young adults, and more women than men; the average age of onset of the disease is about 30. Given that MS patients must take drugs over a period of decades, an oral treatment (one tablet once a day) like laquinimod represents a significant advantage over the products currently on the market, all of which must be injected. In 2007, the total market for MS pharmaceuticals was estimated at USD 7 billion (Cowen & Co, Therapeutic Categories Outlook, March 2008).
