Genzyme to Feature Multiple Sclerosis Pipeline and Present New Data on Aubagio and Lemtrada at ECTRIMS

Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), announced today that its multiple sclerosis pipeline, which includes a new generation of investigational treatments in early development, will be featured during the 30th Congress of the European Committee for Research and Treatment in Multiple Sclerosis (ECTRIMS) being held in Boston Sept. 10-13. The company will also present this week 26 oral and poster presentations from its MS franchise, including four-year results from the Lemtrada™ (alemtuzumab) extension study,12-year MRI data for Aubagio®(teriflunomide), and data from the Aubagio TOPIC study, which was recently published in The Lancet Neurology.

In addition to its marketed therapies, Genzyme has an MS R&D pipeline focused on investigational treatments to address unmet needs for relapsing and progressive forms of MS through research in selective immunomodulation, neuroprotection and remyelination.

Key Genzyme MS programs and collaborations in clinical and preclinical development include:

• Vatelizumab – An investigational anti-VLA-2 humanized monoclonal antibody currently in a Phase II trial for relapsing forms of MS, in partnership with Glenmark Pharmaceuticals.
• GZ402668 – A next-generation investigational anti-CD52 humanized monoclonal antibody currently approaching Phase I clinical development.
• Discovery and research programs evaluating agents promoting remyelination, as well as agents targeted at central nervous system innate immune cells to provide neuroprotection.
• Collaborations with academic medical centers such as Brigham and Women’s Hospital to identify correlative biomarkers of disease progression, and with Cleveland Clinic to explore strategies to address neurodegeneration, a hallmark of progressive MS.

“Since FDA approval of once-daily oral Aubagio two years ago, Genzyme has continued to advance the understanding and treatment of MS by addressing important unmet medical needs for people living with the disease. Between clinical trials and commercial use in more than 40 countries, approximately 30,000 patients have now been treated with Aubagio,” said Genzyme President and CEO David Meeker. “With Lemtrada, we have also made significant progress with approvals in more than 30 countries. With our differentiated marketed therapies and a varied pipeline focusing on innovative treatment approaches and underserved MS patients with progressive disease, we are uniquely positioned to bring long-term value to the MS community.”

About Aubagio® (teriflunomide)
Aubagio is approved in the United States, European Union, Australia, Argentina, Brazil, Canada, Chile, Columbia, Honduras, Mexico, New Zealand, Russia, South Korea, Switzerland, Turkey and Ukraine, with additional marketing applications under review by regulatory authorities globally.

Aubagio is an immunomodulator with anti-inflammatory properties. Although the exact mechanism of action for Aubagio is not fully understood, it may involve a reduction in the number of activated lymphocytes in the central nervous system (CNS). Aubagio is supported by one of the largest clinical programs of any MS therapy, with more than 5,000 trial participants in 36 countries. Some patients in extension trials have been treated for up to 10 years.

About Lemtrada™ (alemtuzumab)
Lemtrada is approved in the European Union, Australia, Canada, Mexico, Brazil, Argentina, Chile and Guatemala. Lemtrada is currently not approved in the United States. The U.S. Food and Drug Administration (FDA) has accepted for review the company’s resubmission of its application seeking approval of Lemtrada, and Genzyme expects FDA action on the application in the fourth quarter. Marketing applications for Lemtrada are also under review in other countries. Lemtrada is supported by a comprehensive and extensive clinical development program that involved nearly 1,500 patients and 5,400 patient-years of follow-up.

Alemtuzumab is a monoclonal antibody that selectively targets CD52, a protein abundant on T and B cells. Treatment with alemtuzumab results in the depletion of circulating T and B cells thought to be responsible for the damaging inflammatory process in MS. Alemtuzumab has minimal impact on other immune cells. The acute anti-inflammatory effect of alemtuzumab is immediately followed by the onset of a distinctive pattern of T and B cell repopulation that continues over time, rebalancing the immune system in a way that potentially reduces MS disease activity.

Genzyme holds the worldwide rights to alemtuzumab and has primary responsibility for its development and commercialization in multiple sclerosis. Bayer HealthCare holds the right to co-promote alemtuzumab in MS in the United States. Upon commercialization, Bayer will receive contingent payments based on global sales revenue.
