This study is complementary to a multi-center, randomized, double-blind,parallel-group, placebo-controlled, variable treatment duration study comparing the efficacy and safety of BAF312 to placebo in patients with SPMS (NCT01665144). Investigators will explore both immunological and neuroprotective mechanisms of BAF312 (siponimod), a novel agent in the setting of a SPMS clinical trial.
This study is part of a multi-center study, with the University of Michigan serving as the central site.
