Clinical Trial Summary

This is an open-label, single-arm, multicentre prospective pilot study to assess the efficacy and safety of ofatumumab in patients with AQP4-IgG seropositive neuromyelitis optica spectrum disorder (NMOSD) in China.


Clinical Trial Description

Neuromyelitis optica spectrum disorder (NMOSD) is a rare but severe demyelinating disorder that affects mainly adult patients. It is associated with a pathological B cell-mediated humoral immune response against the aquaporin-4 (AQP4) water channel. Monoclonal antibodies against CD20 have been shown to be effective for prevention of relapses in patients with NMOSD, and therefore been recommended as first-line therapy for this disorder. Ofatumumab (OFA), a fully humanized anti-CD20 monoclonal antibody, has been approved for multiple sclerosis treatment. However, prospective multicenter studies are needed to determine the efficacy and safety of ofatumumab in treating NMOSD. ;
