The aim of the study was to evaluate the effect of Copaxone® (Cop) treatment on relapse rate and disability progression in 104 patients with clinically definite relapsing remitting MS (RRMS) followed up in a 36-month open label study in Moscow MS Center. The mean age of patients at start was 37.5 (0.9) years, mean MS duration – 8.1 (0.6) years, mean EDSS score - 2.54 (0.10). The patients passed through neurological examination every 3 months.
Prior to the start of the DMT they have 1.45 (0.07) relapses per patient per year (149 on the whole), 2.69 (0.13) per patient during previous 2 years (277 on the whole). During these 3 years 42 patients (40.4%) were relapse free, 83 of them (79.8%) do not have EDSS progression. The relapse rate significantly decreased during the first year of treatment – 29 relapses on the whole (p<0,001), mean 0.28 (0.05), and remained stable low during the second year – 27 relapses, mean 0.26 (0.05) and the third year – 28 relapses, mean 0.27 (0.07). Thus in 3 years these 104 patients had only 84 relapses, which is near 2 times lower, then during one year prior to DMT.
During the first year increase in EDSS score was seen in 6 patients (5.8%), the second year – 7 patients (6.7%), the third year – 12 patients (11.5%). Mean EDSS score moved from 2.54 (0.10) at the start to 2.61 (0.13) 36 month later. In 9 patients (8.7%) disease transformed to secondary progressive MS (SPMS) with relapses and Cop treatment was stopped. Local side reactions were seem in 24 patients (26%), systemic reactions - in 9 cases.
Thus, in this group of patients Cop (used in every-day neurological practice) during the whole 3-year period showed stable positive influence on RRMS course – significant decrease of relapse rate, no EDSS progression in up to 80% of patients and good tolerability.
