Exploration of Novel Imaging Biomarkers on OCT for Ublituximab Treatment Response in Multiple Sclerosis

The purpose of the research study is to explore new retinal imaging biomarkers of immune cell activity in MS during use of ublituximab (Briumvi) treatment. A biomarker is a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. This study will evaluate the efficacy of ublituximab to modulate MS pathology in a new manner. In order to assess this new biomarker, a specialized optical coherence tomography (OCT) scan will be performed at enrollment into the study and at 2 other timepoints throughout the study. Subjects asked to take part in this study should have been diagnosed with relapsing multiple sclerosis (MS) and have recently been advised to start the medication ublituximab (Briumvi) or are currently on another medication for the treatment of their MS. We plan to enroll 30 patients into this study. Fifteen (15) patients with Relapsing Remitting Multiple Sclerosis (RRMS) who are being initiated on B-cell depletion therapy by their treating physician at the University of Maryland Center for MS Treatment and Research will be offered enrollment into this study. Additionally, 15 age/sex matched patients with stable RRMS who are not undergoing any change in treatment and are not currently on B-cell depleting therapies will be enrolled as control subjects.
