The synthetic polypeptide copolymer-1 (Cop-1; Copaxone; Glatiramer Acetate) has been recently approved as an effective treatment in relapsing multiple sclerosis (MS). A large body of evidence demonstrates that Cop-1 induces active suppression of CNS-inflammatory disease in animal models. However, Cop-1-mediated suppressor mechanisms have not yet been elucidated in humans. A 12-month open study following clinical and immunological parameters of ten relapsing MS patients treated with Cop-1 is presented. Relapse rates and disability scores (EDSS) were evaluated prior to and after 12 months of treatment. The immunological parameters assessed prior to and at 3 months' interval during treatment included serum levels of soluble IL-2 receptor (sIL-2R) and IL-10 as well as leukocyte cytokine mRNA expression of TNF alpha, IL-4 and TGF-beta. Copaxone treatment was found to lead to a significant reduction in the mean annual relapse rate (from 1.4 prior to treatment to 0.6 during treatment) and stabilization of disability in 90% of the patients. The treatment was accompanied by an elevation of serum IL-10 levels, suppression of the pro-inflammatory cytokine TNF alpha mRNA, and an elevation of the anti-inflammatory cytokines TGF-beta and IL-4 mRNAs in PBLs. These results suggest that the beneficial clinical effects of Copaxone in MS patients may be attributed to changes in activation of T cell subsets and a shift from Th1 to Th2/Th3 cytokine profile, probably leading to Cop-1-driven mechanisms of bystander suppression.
