Long-Term Study Shows COPAXONE(R) Significantly Slows Progression of Disability and Reduces Relapse Rates in Patients with Relapsing-Remitting Multiple Sclerosis

JERUSALEM--(HSMN NewsFeed)--Data from a 16-year follow-up study of 174 relapsing-remitting multiple sclerosis (RRMS) patients was presented at the 23rd Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). The study demonstrates significant clinical benefits on both disability and relapse rates in patients continuously treated with COPAXONE® (glatiramer acetate injection) for an average of 8 years. The majority of patients (84.8 percent) in the ongoing cohort (n=112), who continuously received COPAXONE® showed either unchanged or improved disability scores, as measured by Expanded Disability Status Scale (EDSS). In contrast, more than half of patients (56.2 percent) who discontinued treatment after an average of 3.7 years showed accumulated disability. In addition, 76 percent of patients who remained on COPAXONE® were still walking unaided after an average of 20 years of disease duration.

In addition to improved EDSS scores, patients who continuously received COPAXONE® and were adherent to therapy experienced significantly reduced annualized relapse rates (ARR) compared to baseline (less than one relapse every 4.7 years), with more than half of patients (56.9 percent) remaining relapse-free while on treatment.

"The results of this study demonstrated the sustained positive effects of COPAXONE® on slowing disease activity and accumulation of disability in RRMS patients, and further support the drug's excellent long-term safety profile," said Adriana Carra, M.D., Department of Neurology, Hospital Britanico de Buenos Aires. "The results are consistent with the previously published 10-years long-term data demonstrating the long-term efficacy of COPAXONE® and the drug's beneficial impact on the chronic clinical course of RRMS."

About the Study

The 16-year study, which represents the longest prospective open-label follow up of RRMS patients in Latin America, evaluated the long-term efficacy and safety of COPAXONE® (glatiramer acetate injection) by examining disability progression and relapse rate among patients who received continuous treatment, and comparing the disease course of these patients to those who withdrew from the study. The observational study, which began in May of 1990, was conducted in eight MS centers in Argentina.

174 treatment naive RRMS patients were included. Patients were aged between 18-55 years, had experienced two or more relapses in the previous two years and had EDSS disability score below six. Patients with secondary progressive MS and those using immunosuppressant therapies or long-term corticosteroids were excluded. All patients received 20mg dose of COPAXONE® daily by self-injections and had full neurological examinations and EDSS scores determined every six months.

Of the ongoing COPAXONE® treated cohort, 112 patients (64.3 percent) remained in the study for an average of eight years. Of the 62 patients who withdrew from the study (after an average of 3.7 years) 32 (52.5 percent) returned for a single long-term follow up (LTFU) visit.

The clinical features of disability among participants were compared to results from Drs. Weinshenker and Confavreux (Brain 1991, 2006) and an Argentinian natural history cohort of 508 RRMS patients who voluntarily refused treatment or were unable to receive treatment because they had no social security coverage. The data cut-off period for the analysis was in March 2007.

About MS

Multiple Sclerosis (MS) is the leading cause of neurological disability in young adults. It is estimated that 400,000 people in the United States are affected by this disease, and that over one million people are affected worldwide. MS is a progressive, demyelinating disease of the central nervous system affecting the brain, spinal cord and optic nerves.

Patients with MS may experience physical symptoms and/or cognitive impairments, including weakness, fatigue, ataxia, physical dysfunction, bladder and bowel problems, sensory effects, and visual impairment. MS also has a significant impact on the sufferers' social functioning and overall quality of life.


Current data suggest COPAXONE® (glatiramer acetate injection) is a selective MHC (Major Histocompatability Complex) class II modulator. COPAXONE® is indicated for the reduction of the frequency of relapses in RRMS. The most common side effects of COPAXONE® are redness, pain, swelling, itching, or a lump or an indentation at the site of injection, weakness, infection, pain, nausea, joint pain, anxiety, and muscle stiffness.

COPAXONE® (glatiramer acetate injection) is now approved in 47 countries worldwide, including the United States, Canada, Mexico, Australia, Israel, and all European countries. In Europe, COPAXONE® is marketed by Teva Pharmaceutical Industries Ltd. and sanofi-aventis. In North America, COPAXONE® is marketed by Teva Neuroscience, Inc.
