COPAXONE(R) Significantly Reduced Disease Severity in Long-Term Treated Multiple Sclerosis PatientsData from Longest, Continuous Study of MS Treatment Presented at European Committee for Treatment and Research in MS
JERUSALEM--(HSMN NewsFeed)--Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA ) today presented data that demonstrated patients treated for 10 and 15 years with COPAXONE(R) (glatiramer acetate injection) had significant reduction in disease severity. These data, generated from the longest continuous prospective study of any disease modifying therapy in relapsing remitting multiple sclerosis (RRMS), were presented today at the 25th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Düsseldorf, Germany.
The long-term analysis utilized the universal MS Severity Score (MSSS) to evaluate the accumulation of disease severity in long-term COPAXONE(R) patients actively on therapy and those who withdrew early from the 15 year ongoing COPAXONE(R) clinical trial1. Results demonstrated that 51 percent of long-term COPAXONE(R) treated patients shifted to lower severity grades (p<0.0001). In contrast, 41 percent of patients who withdrew from COPAXONE(R) showed a deterioration in MSSS grades, when compared to their baseline severity grades. Patients remaining on long-term treatment (treatment exposures of 10.12±1.32 years and 13.6±1.3 years), had improved median MSSS scores of 1.84 and 1.69 at 10 and 15 years, compared to MSSS scores at start, 3.62 and 3.50, respectively. Median MSSS score for withdrawn patients worsened to 6.01 at long-term follow-up versus 4.30 at treatment initiation.
“This study, along with other MSSS studies, is paving the way to enable neurologists to predict the progression of disease severity in MS patients,” said Joseph Herbert, M.D., associate professor, NYU Department of Neurology and principal investigator of the study. “The demonstrated positive impact of long-term COPAXONE(R) treatment on slowing disease progression provides hope to MS patients and further emphasizes the importance of early treatment initiation.”
About the Analysis
The modified intention-to-treat cohort (mITT, N=232) included all study patients receiving =1 COPAXONE(R) dose. Of mITT, 108 and 100 patients were ongoing in the trial at 10 and 15 years, respectively. Of the 124 patients who withdrew by the 10th year of the study, 50 patients returned for a long-term follow-up. MSSS scores were generated at the onset of COPAXONE(R) treatment, at last patient observation for all those who were on COPAXONE(R) and withdrew, at 10 and 15 year visits for ongoing patients and at 10 year long-term follow-up for withdrawn patients who returned.
At the 10 year long-term follow-up, mean disease duration for withdrawn patients was 18.54 ± 5.91 years and mean time since leaving study for the withdrawn patients was 5.44±2.89 years. Median MSSS scores for ongoing patients were 1.84 and 1.69 at 10 and 15 years, compared to MSSS scores at COPAXONE(R) (glatiramer acetate injection) therapy start, 3.62 and 3.50, respectively. For 50 withdrawn patients, median MSSS score was 6.01 at LTFU vs. 4.30 at COPAXONE(R) treatment initiation.
During the study, there was a significant difference between ongoing patients at 10 and 15 years and those who eventually withdrew, in the shift toward lower disease severity categories from COPAXONE(R) start to last patient observation on COPAXONE(R) (p<0.0001). There was a significant difference in disease severity between ongoing patients at 10 years and withdrawn patients at 10 year long-term follow up. Only 11 percent of ongoing, compared with 41 percent of withdrawn patients, had shifted to higher severity scores; while 51 percent of ongoing, compared to only 24 percent of withdrawn, had shifted to lower severity scores (p<0.0001).
The study was supported by Teva Neuroscience.
COPAXONE(R) is indicated for the reduction of the frequency of relapses in RRMS, including patients who have experienced a first clinical episode and have MRI features consistent with multiple sclerosis. The most common side effects of COPAXONE(R) are redness, pain, swelling, itching, a lump or an indentation at the site of injection, weakness, infection, pain, nausea, joint pain, anxiety, and muscle stiffness.
COPAXONE(R) is now approved in 51 countries worldwide, including the United States, Canada, Mexico, Australia, Israel, and all European countries. In North America, COPAXONE(R) is marketed by Teva Neuroscience, Inc., which is a subsidiary of Teva Pharmaceutical Industries Ltd. (NASDAQ:TEVA ).
