Genzyme to Present New Data from AUBAGIO® and LEMTRADATM Clinical Development Programs at ECTRIMS

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), announced today new data from Genzyme’s clinical development programs for AUBAGIO® (teriflunomide) and LEMTRADATM (alemtuzumab) will be presented at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Lyon, France, October 10-13.

“The data to be presented at ECTRIMS are a reflection not only of the comprehensive clinical development programs supporting AUBAGIO and LEMTRADA, but of the unique commitment and substantial progress Genzyme has made to date in bringing forward differentiated therapies in multiple sclerosis,” said Genzyme CEO and President, David Meeker.

Once-daily, oral AUBAGIO is now commercially available in the U.S. following FDA approval in patients with relapsing forms of MS. Marketing applications for AUBAGIO and LEMTRADA are currently under review by the EMA and other regulatory authorities.

Key data from across the company’s clinical development programs to be presented are as follows. Abstracts are available on the ECTRIMS website.

TOWER is a randomized Phase III trial assessing once-daily oral AUBAGIO (teriflunomide) in patients with relapsing multiple sclerosis. It is the second Phase III study for AUBAGIO.

  • Effect of alemtuzumab vs. Rebif® on brain MRI measurements: Results of CARE-MS II (Poster Session 2 – P877; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Safety of alemtuzumab in relapsing-remitting multiple sclerosis patients who relapsed on prior therapy (Poster Session 1 – P545; October 11; 3:30 p.m. CEST, 9:30 a.m. EDT).

Additional Genzyme MS portfolio data, in addition to the Genzyme satellite symposia to be featured at ECTRIMS include:

  • Teriflunomide treatment of human monocyte-derived dendritic cells in vitro does not impair their maturation or ability to induce allogeneic T-cell responses (Poster Session 2 – P950; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Effect of teriflunomide on immune responses to seasonal influenza vaccination in patients with relapsing multiple sclerosis: results from the TERIVA study (Poster Session 2 – P925; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Effect of teriflunomide on the pharmacodynamic and pharmacokinetic profiles of warfarin in healthy male subjects (Poster Session 1 – P453; October 11; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Pregnancy outcomes from the teriflunomide clinical development programme: retrospective analysis of the teriflunomide clinical trial database (Poster Session 2 – P737; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Effect of teriflunomide on lymphocyte and neutrophil levels in patients with relapsing multiple sclerosis: results from the TEMSO study (Poster Session 2 – P995; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).


  • Autoimmunity in patients treated with alemtuzumab for relapsing-remitting multiple sclerosis (Poster Session 2 – P1005; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Lymphocyte subset dynamics following alemtuzumab treatment in the CARE-MS I study (Poster Session 2 – P935; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).
  • Therapeutic treatment with an anti-mouse CD52 antibody reverses disease symptoms in a murine EAE model of multiple sclerosis (Poster Session 2 – P908; October 12; 3:30 p.m. CEST, 9:30 a.m. EDT).

About AUBAGIO® (teriflunomide)

The U.S. Food and Drug Administration (FDA) has approved AUBAGIO® (teriflunomide) as a once-daily, oral immunomodulator indicated for patients with relapsing forms of multiple sclerosis (MS). The ongoing AUBAGIO clinical development program, involving more than 5,000 patients in 36 countries, is among the largest of any MS therapy. Some patients in extension trials have been treated up to 10 years.

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).

About Alemtuzumab/LEMTRADA™

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 retains an option to co-promote alemtuzumab in multiple sclerosis. Bayer HealthCare has notified Genzyme of its intention to co-promote under this option. Upon regulatory approval and commercialization, Bayer would receive contingent payments based on sales revenue.

LEMTRADA™ is the proprietary name submitted to health authorities for the company’s investigational multiple sclerosis agent alemtuzumab.
