About this study

Rationale: Ocrelizumab is widely and effectively used to treat relapsing multiple sclerosis (RMS). Phase II studies and data from large patient cohorts indicate that rituximab, another anti-CD20 monoclonal antibody, is probably equally effective and safe as ocrelizumab in the treatment of RMS. An advantage of rituximab is a considerably lower price. Therefore we will start a study aimed at demonstrating non-inferiority of rituximab compared to ocrelizumab in RMS. If non-inferiority of rituximab can be shown, important reductions in the cost of treatment of RMS will be possible, without loss of efficacy. Objective: Evaluating the efficacy and safety of ritixumab compared to ocrelizumab in the treatmens of RMS. Study design: Randomized double blind multi-centre non-inferiority study of rituximab compared to ocrelizumab in 200 patients with RMS. The trial duration will be 30 months Study population: The study population consists of 200 adult RMS patiens with an indication to start anti-CD20 monoclonal antibody treatment. Intervention: Patients will be randomized 1:1 into the standard group (ocrelizumab treatment) or the experimental group (rituximab treatment). Main study parameters: To conclude non-inferiority of rituximab there will be one primary endpoint: the proportion of patients free of inflammatory disease activity (defined as: new or enlarged T2 lesions) between week 24 (M6) and week 96 (M24) of treatment in each arm. Secondary trial endpoints are presence and numb…
