简要总结
The goal of this prospective, multi-center, non-blinded, non-randomized, non-intervention clinical trial is to compare immunologic, virologic and epigenetic factors in patients with active multiple sclerosis in standard 2.line treatment with ocrelizumab, rituximab, ofatumumab or natalizumab in Region Midt, Denmark. It aims to answer how the immunologic, virologic and epigenetic response in these patients are compared to healthy controls, and analyze their treatment effect in relation to this response. Participants will get an extra blood sample, when they have their routine blood samples taken.
详细描述
The CoSHED RMS study will include patients with active multiple sclerosis aged 18-65 years fulfilling the criteria for 2. line treatment and starting treatment with one of the four high-efficacy disease modifying treatments ocrelizumab, rituximab, ofatumumab or natalizumab. Researchers will compare immunologic, virologic and epigenetic parameters in the four treatment groups to a age and gender matched healthy control group. The study duration is 12 months, and patients can continue in an extension phase for additional 12 month. The primary endpoint is changes in B cell populations between the four treatments within 12 months. The study will evaluate a number of efficacy and safety endpoints using clinical, MRI, routine blood samples and research biomarkers.

排除标准
- •Pregnancy or breast feeding
