Secondary progressive MS

Brief Summary

This is a Phase 3 clinical trial. Its aim is to demonstrate the efficacy and safety of an investigational drug compared to placebo in participants with Secondary Progressive MS. Globally, approximately 868 participants will be randomly assigned to the investigational drug or placebo. This is a double-blind study. This means the study doctor and participant will not know if they are receiving the investigational drug or placebo. Participants will receive an intravenous infusion once a month (every 4 weeks). The study is expected to last between 2.5 and 4.5 years.
