Genzyme receives FDA approval for AUBAGIO to treat relapsing forms of MS

Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), announced today that the U.S. Food and Drug Administration (FDA) has approved AUBAGIO^® (teriflunomide) as a new once-daily, oral treatment indicated for patients with relapsing forms of multiple sclerosis (MS). AUBAGIO has shown significant efficacy across key measures of MS disease activity, including reducing relapses, slowing the progression of physical disability, and reducing the number of brain lesions as detected by MRI.    

"We are very excited to introduce AUBAGIO as a new treatment option that can make a difference in the lives of people with multiple sclerosis," said David Meeker, President and CEO, Genzyme. "The approval of our first MS therapy represents an important milestone for Genzyme and underscores our commitment to long-term leadership and partnership in the MS community."    

The FDA approval was based on efficacy data from the TEMSO (riflunomide ultiple clerosis ral) trial. In the Phase III TEMSO trial, AUBAGIO 14 mg significantly reduced the annualized relapse rate (p=0.0005) and the time to disability progression (p=0.0279) at two years versus placebo in patients with relapsing forms of multiple sclerosis. AUBAGIO 7 mg significantly reduced the annualized relapse rate (p=0.0002) in the trial.

"Many people living with MS struggle with the additional burden of injectable therapies administered daily to weekly," said Dr. Aaron E. Miller, Medical Director, The Corinne Goldsmith Dickinson Center for Multiple Sclerosis, Mount Sinai Medical Center. "The FDA's approval of AUBAGIO, a new oral treatment option, is an encouraging advancement for the MS community and may be a valuable treatment for people living with this often debilitating disease."

The ongoing AUBAGIO clinical development program, involving more than 5,000 patients in 36 countries, is amongst the largest of any MS therapy. Some patients in extension trials have been treated for up to 10 years.

"We are greatly encouraged to see a new oral therapeutic option become available to people living with MS," said Dr. Timothy Coetzee, Chief Research Officer at the National MS Society. "With collaborative research underway around the world today, this is an extremely hopeful time for anyone who is diagnosed with MS."

The AUBAGIO label includes a boxed warning citing the risk of hepatotoxicity and, teratogenicity (based on animal data).

In MS clinical studies with AUBAGIO, the incidence of serious adverse events were similar among AUBAGIO and placebo-treated patients. The most common adverse events associated with AUBAGIO in MS patients included increased ALT levels, alopecia, diarrhea, influenza, nausea and paresthesia.

The labeling for AUBAGIO was also informed by the estimated 2.1 million years of patient exposure globally since the launch of leflunomide, which is indicated in the U.S. for the treatment of rheumatoid arthritis. Teriflunomide is the principal active metabolite of leflunomide. Severe liver injury including fatal liver failure has been reported in patients treated with leflunomide.
