JERUSALEM, Israel--(BUSINESS WIRE)--A new study showed that very active patients who received COPAXONE® (glatiramer acetate injection) therapy alone following short-term induction treatment with mitoxantrone experienced an 89 percent greater reduction (P<0.0001) compared to those receiving COPAXONE® alone, in Magnetic Resonance Imaging (MRI)-disease activity as measured by Gadolinium (Gd) enhancing lesions of the brain. This initial benefit achieved early on in the study was maintained over the entire 15-month study period. In addition, no adverse events outside of those associated with either treatment when used as monotherapy were observed.
