Immunoadsorption Versus High-dose Intravenous Corticosteroids in Relapsing Multiple Sclerosis

Immunoadsorption Versus High-dose Intravenous Corticosteroids in Relapsing Multiple Sclerosis - Assessment of Mechanism of Action

Treatment of acute relapsing multiple sclerosis (MS) has remained largely unaltered within past years. However, evidence defining the exact role of apheresis treatment in the therapeutic sequence is still incomplete. INCIDENT-MS evaluates the mechanism of action of immunoadsorption compared to escalated methyl prednisolone treatment in steroid-refractory MS relapses and thereby will help to identify predictive markers for optimal treatment choice and will generate further insights into the pathophysiology of MS relapses.

Inclusion Criteria:

Exclusion Criteria:

• Baseline EDSS score >6.5 points
• Previous administration of less than 3x1000mg or more than 5x1000mg IVMPS for initiation treatment
• Known pregnancy or rejection to perform a pregnancy test (female patients only)
• Immunosuppressive treatment for conditions other than multiple sclerosis
• Ongoing neoplastic disorder or past neoplastic disorder within previous five years
