Additional Relevant Details Top-line results from the Phase 2 SYNERGY study evaluating opicinumab (anti-LINGO-1), an investigational, fully human monoclonal antibody being developed as a potential neuroreparative therapy in people with relapsing forms of multiple sclerosis (RMS). In the study, opicinumab missed the primary endpoint, a multicomponent measure evaluating improvement of physical function, cognitive function, and disability. However, evidence of a clinical effect with a complex, unexpected dose-response was observed.
