Rituximab in Chronic Inflammatory Demyelinating Polyneuropathy

NCT04480450 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2025-09-17

No results posted yet for this study

Summary

CIDP is a heterogeneous disease with variable responses to therapy. Recently, a distinctive subgroup of patients with serum autoantibodies to the paranodal proteins contactin and neurofascin have been identified. Although they present with active and serious disease, multiple clinical reports suggest that these patients can be cured with a treatment that depletes B cells and presumably eliminates pathogenic autoantibodies. However, beyond that subgroup of CIDP patients, which CIDP patients might benefit from Rituximab and B cell depletion is unknown. This Phase II study will treat 3 homogenous groups of 16 CIDP patients each with Rituximab in order to determine if there are subgroups that can be taken off current medications and put into long-term remission. The results from this study will be used to design a future larger trial. Biomarkers including paranodal antibodies, serum neurofilament light chains, anti-ganglioside antibodies will be obtained in order to learn about disease pathogenesis and possibly target therapy

DRUG

Rituximab

Rituximab is a highly purified, 1328-amino acid antibody with an approximate molecular mass of 145 kD. Rituximab is a mouse human chimeric monoclonal antibody against CD20. Administration leads to between 90 and 100% peripheral B cell depletion via complement dependent cytotoxicity.
