Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to assess effects of B cell depletion on the immune system in patients with relapsing forms of multiple sclerosis (MS) treated with ocrelizumab. This will be done by collecting blood from patients starting treatment with ocrelizumab before the first infusion and before the infusions at 6 and 12 months. The effects on the immune system will be assessed by performing transcriptome profiling of immune cells, measuring serum levels of microRNAs, and analyzing serum autoantibody immune signatures using antigen arrays. In addition, blood will be collected once from a group of healthy individuals to serve as controls.
