Abstract

Ocrelizumab is the first disease-modifying drug registered in primary progressive multiple sclerosis. Before the registration of ocrelizumab, these disease-modifying drugs were available only for patients with relapsing-remitting and secondary progressive multiple sclerosis. Ocrelizumab is an anti-CD20 monoclonal antibody that reduces B-cell counts in the blood. Ocrelizumab was registered after the pivotal ORATORIO study showed that it slows down disease progression in patients with primary progressive multiple sclerosis.


European Medicines Agency approved ocrelizumab for use in the treatment of adult patients with relapsing forms of multiple sclerosis and early primary progressive multiple sclerosis, assessed by means of a duration of the disease and level of disability as well as radiological features characteristic of inflammatory activity.
