How does RITUXAN work for NMO?
Rituximab targets the CD20 antigen on B-cells and leads to profound B-cell depletion, principally over an antibody-dependent cell cytotoxicity mechanism and decreases attack frequency and severity in patients with NMO; however, it does not remove attacks, even when modifying treatment to achieve B-cell depletion.
Is Rituximab Approved for NMO?
Rituximab has been predominantly used in NMO patients as immunosuppressive therapy to prevent relapses, especially in those who do not respond well to other drugs such as AZA and mycophenolate. It is also being increasingly used as a first-line drug in patients with severe form of NMO.

Rituximab (RTX) is a mouse–human chimeric monoclonal antibody specific for the CD20 antigen on B lymphocytes and used to treat many autoimmune diseases.
How is the effectiveness of rituximab measured in the EDSS?
Rituximab (RTX) is a mouse–human chimeric monoclonal antibody specific for the CD20 antigen on B lymphocytes and used to treat many autoimmune diseases. Disability and relapses were measured using the Expanded Disability Status Scale (EDSS) and annualized relapse rate (ARR) ratio to evaluate the effectiveness of RTX.
How often should I take rituximab at 24 weeks?
Rituximab (375 mg/m 2) was administered intravenously every week for 4 weeks, then 6-month interval dosing was done (1000 mg every 2 weeks, at 24 weeks and 48 weeks after randomisation). A matching placebo was administered intravenously.
