Kremenchutzky M, Rice GPA, Baskerville J, Wingerchuk DM, Ebers GC. The resulting lymphocyte depletion modulates the immune response, but the exact mechanism of action of ocrelizumab in multiple sclerosis is currently uncertain. This is an open-label, multicenter, biomarker study designed to be hypothesis-generating in order to better understand the mechanism of action of ocrelizumab and B-cell biology in RMS. Consider therapy modification, Tacrolimus (Topical): May enhance the adverse/toxic effect of Immunosuppressants. J Neurol.

Genentech, Inc. January 2021. Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Multiple sclerosis (MS) is a condition that affects the nervous system, including the brain, spinal cord, and optic nerves. Mechanism of Action. The pooled data of OCREVUS clinical studies (RMS and PPMS) and their open-label extensions (up to approximately 7 years of exposure) have shown an association between decreased levels of immunoglobulin G (IgG
