• Multiple sclerosis (MS) is a chronic systemic autoimmune disorder characterized by plaques of demyelination, autoimmune inflammation, and astrocytic gliosis. The primary cells involved in the pathophysiology of MS are T cells. However, B cells have recently been implicated in the pathophysiology of the disease. Therefore, researchers have been exploring B cell therapy as an alternative treatment option for MS. B cell therapy is based on the targeted depletion of CD20-positive B cells. Rituximab, ocrelizumab, and ofatumumab are anti-CD20 antibodies already approved. Briumvi, the fourth type of anti-CD20 antibody was approved by FDA in December 2022, for the treatment of relapsing types of MS, including relapsing-remitting multiple sclerosis, active secondary progressive multiple sclerosis, and clinically isolated syndromes after the drug was tested in two randomized, double-blind, phase III, ULTIMATE I, and II trials which compared Briumvi (ublituximab) with Aubiago (teriflunomide). Ublituximab was found to have a much lower annual relapse rate in the ULTIMATE II trials than teriflunomide. Briumvi is a chimeric recombinant IgG1 monoclonal antibody directed against human CD20 with potential antineoplastic activity. Its mechanism of action involves several distinct processes that collectively lead to the depletion of B cells and suppression of the immune response. The primary mode of action of Briumvi is its high-affinity binding to CD20. Infusion-related reactions are the most common side effects encountered following intravenous administration of ublituximab.
