CAMBRIDGE, Mass. — An orally administered drug made by Genzyme for treating multiple sclerosis did not appear superior to a biotech drug already on the market, according to results of a late-stage clinical trial.
Genzyme, owned by French drug maker Sanofi, compared the once-daily drug teriflunomide with Rebif (interferon beta-1a), made by Pfizer and Merck KGaA, in patients with relapsing MS in the 324-patient "TENERE" trial. Merck KGaA, based in Germany, operates under the name EMD Serono in the United States to avoid confusion with U.S.-based Merck & Co.
