Effects of Ublituximab on Motor Functions in Multiple Sclerosis

Summary

The purpose of this study is to test if ublituximab changes walking functions and fall risk in people with relapsing multiple sclerosis (RMS). Twenty-five qualified people with RMS will undergo a 48-week ublituximab treatment. Before, 24 weeks into, and after the treatment, their ambulatory function, disability status, and cognition will be assessed. Additionally, they will experience large-scale slip perturbations on a treadmill under the protection of a safety harness at the last assessment. The outcome measures will be compared across the assessments to examine the effects of ublituximab on improving their walking function, disability status, cognition, and the responses to the unexpected slip perturbation.
