“Clinical studies demonstrated TECFIDERA was an effective therapy with a favorable safety profile for people with relapsing-remitting MS,” said Professor Gavin Giovannoni, Chair of Neurology, Blizard Institute, Barts and The London School of Medicine and Dentistry. “This, combined with its interesting suggested mechanism of action, should position TECFIDERA as a first-line therapy choice.”The most common side effects associated with TECFIDERA seen in clinical trials are flushing and gastrointestinal (GI) events (i.e., diarrhea, nausea, and abdominal pain). Other side effects include a decrease in mean lymphocyte counts during the first year of treatment, which then plateaued. There was no increased risk of malignancy or serious infections associated with TECFIDERA treatment, and no opportunistic infections were observed. The European Commission decision on TECFIDERA is expected in approximately two months. TECFIDERA will mark the fourth therapy Biogen Idec offers people living with MS. About TECFIDERA™ TECFIDERA™ (dimethyl fumarate) is an oral therapeutic candidate for the treatment of multiple sclerosis (MS). TECFIDERA is the only currently known investigational compound for the treatment of relapsing-remitting MS that has experimentally demonstrated activation of the Nrf-2 pathway. This pathway provides a way for cells in the body to defend themselves against inflammation and oxidative stress caused by conditions like MS. In 2011 and 2012, Biogen Idec announced positive data from DEFINE and CONFIRM, two global, placebo-controlled Phase 3 clinical trials that evaluated 240 mg of TECFIDERA, administered either twice a day (BID) or three times a day (TID), for two years. TECFIDERA is also currently under review by regulatory authorities in the United States, Australia, Canada and Switzerland. About Multiple Sclerosis Multiple sclerosis (MS) is a chronic, often disabling disease that attacks the central nervous system (CNS), which is made up of the brain, spinal cord and optic nerves. Symptoms may be mild or severe, ranging from numbness in the limbs to paralysis or loss of vision. The progression, severity, and specific symptoms of MS are unpredictable and vary from one person to another. MS affects an estimated 2.5 million people worldwide, 1 with approximately 400,000 sufferers in the European Union. 2 Relapsing-remitting MS is the most common form of the disease, accounting for 85 percent of cases, and is characterized by clearly defined acute attacks with full recovery or with residual deficit upon recovery. 3 About Biogen Idec Through cutting-edge science and medicine, Biogen Idec discovers, develops and delivers to patients worldwide innovative therapies for the treatment of neurodegenerative diseases, hemophilia and autoimmune disorders.
