Biogen Idec and Fumapharm have announced positive results from a Phase II study designed to evaluate the efficacy and safety of BG-12, an oral fumarate, in patients with relapsing-remitting multiple sclerosis (MS).

The study achieved its primary endpoint, demonstrating that treatment with BG-12 led to a statistically significant reduction in the total number of gadolinium-enhancing brain lesions as measured by MRI with six months of treatment versus placebo.
