Study Showed Significant and Sustained Efficacy Of COPAXONE(R) Alone Following Short-Term Combination Therapy With IV Steroids in Multiple Sclerosis PatientsNew Data on COPAXONE(R) in Combination Use Presented as Late-Breaking News at ECTRIMS
JERUSALEM--(HSMN NewsFeed)--A new study showed that continuing treatment with COPAXONE® (glatiramer acetate injection) alone, produced pronounced, early and sustained effects on disease activity, following 6 months combination therapy with IV steroids. Multiple sclerosis (MS) patients (n=89) with very active disease, having an average of 5.4 gadolinium (T(1)-W Gd) enhancing lesions at entry as measured by Magnetic Resonance Imaging (MRI) experienced a 65% reduction (p less than 0.0001) in lesions during treatment with COPAXONE® and IV steroids in the first six months of the study. This reduction was sustained for an additional six month period when patients received COPAXONE® alone.
These data were presented yesterday as late-breaking news at the 22nd Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), in Madrid, Spain.
Patients in this study also experienced a reduction in mean annualized relapse rate (ARR) from the pre-study baseline of 1.65 +/- 0.74 down to 0.55 and 0.45 during the first and the second study periods, respectively. Results also showed that patients who completed the study experienced a significant decrease in mean converted Kurtzke Expanded Disability Status Scale (EDSS) score as measured after 12 months of treatment as compared to baseline (-0.15, 95 percent CI, -0.13, p=.0323).
"In this patient population with highly active disease as shown by baseline MRI scans, the rapid and significant reduction of brain lesions achieved with COPAXONE® combined with short-term IV steroid was sustained for an additional six months with COPAXONE® alone," said Clive Hawkins, D.M., F.R.C.P., Professor of Clinical Neurology, Keele University, Consultant Neurologist to the Regional Neuroscience Centre, Stoke-on-Trent, UK and the lead investigator in this study. "These data may be important for physicians making decisions on how to treat patients with very active disease as characterized by frequent or disabling relapses, or those who do not respond optimally to traditional first-line therapies." added Hawkins.
About the Study
This open-label, one-arm study examined short-term combination therapy of COPAXONE® and the IV steroid methylprednisolone (IVMP), followed by ongoing treatment with COPAXONE® alone. Patients with at least two T(1)-weighted gadolinium (T(1)-W Gd) enhancing lesions and an EDSS score of less than or equal to 4.0 at the time of screening received COPAXONE® (glatiramer acetate injection) 20mg once daily along with monthly 1g IVMP for six months. After six months, patients continued to receive COPAXONE® alone for an additional six months.
Disease activity assessed by MRI scans in the first six month period demonstrated a 65 percent reduction (p less than 0.0001) in the number of T(1)-W Gd-enhancing lesions from baseline. This reduction was sustained in the second six month period and showed no statistical difference from the change achieved in the first six months (ratio 0.75) as shown by a non-inferiority analysis for the change.
Adverse events throughout the 12-month study period were similar to the safety profile of COPAXONE® alone.
Teva will be issuing a press release regarding additional data presented at ECTRIMS on the efficacy and safety of COPAXONE® treatment after induction therapy with mitoxantrone, which will be posted at www.tevapharm.com.
Current data suggest COPAXONE® (glatiramer acetate injection) is a selective MHC 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 at the site of injection, weakness, infection, pain, nausea, joint pain, anxiety, and muscle stiffness.
COPAXONE® is now approved in 44 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.
