About this study

Researchers are testing whether clemastine fumarate, a drug, can help repair myelin damage in people with multiple sclerosis. The trial will use multi-parametric MRI and UTE MRI to see if clemastine fumarate has a protective or reparative effect on chronic lesions found in patients with relapsing-remitting MS.

Based on ClinicalTrials.gov records.
