What is it?

The active substance is ocrelizumab. Ocrelizumab is a humanized monoclonal antibody that targets and removes CD20 positive B lymphocytes (a type of white blood cell) which contribute to nerve damage in MS. When targeted B cells are removed by ocrelizumab, inflammation is reduced and the chance of other nerve cells being affected is lessened.
