Title: A Phase III, Multicentre, Randomized, Parallel-group, Double-blind, Placebo Controlled Study to Evaluate the Efficacy and Safety of Ocrelizumab in Adults With Primary Progressive Multiple Sclerosis
Brief Summary: This randomized, parallel group, double-blind, placebo controlled study will evaluate the efficacy and safety of ocrelizumab in participants with primary progressive multiple sclerosis. Eligible participants will be randomized 2 : 1 to receive either ocrelizumab or placebo.
