Objectives: To compare the clinical and radiological effectiveness of ocrelizumab in primary progressive multiple sclerosis (PPMS) and relapsing-remitting multiple sclerosis (RRMS) in a clinical practice setting and describe its tolerability and adverse events.
Methods: A retrospective observational cohort study was conducted comparing clinical and magnetic resonance imaging (MRI) data of all patients with (pw)PPMS and RRMS who had received treatment with ocrelizumab at least one cycle and have been followed up for one year at minimum.
Results: 42 patients (27 women) treated with ocrelizumab: 29 had RRMS and 13 PPMS.
