Summary

This study tested clemastine fumarate, an old allergy medicine, to see if it could repair damaged nerves in people with relapsing-remitting multiple sclerosis (MS). Fifty adults with MS took either the drug or a placebo for up to 3 months while continuing their usual MS treatments. The goal was to measure improvements in nerve signaling using eye tests and brain scans.
