JERUSALEM--(BUSINESS WIRE)--New data presented today provided evidence that long-term treatment with COPAXONE® (glatiramer acetate injection) may offer sustained protection from neuronal/axonal injury. This protective effect was reflected biologically by a significant increase in N-acetylaspartate (NAA), a specific marker of neuronal mitochondrial function, in treated versus non-treated relapsing-remitting multiple sclerosis (RRMS) patients. These six-year results augment previously published findings suggesting that treatment with COPAXONE® may provide a neuroprotective effect in RRMS patients1, 2.
