Mechanism of action
- B-lymphocyte antigen CD19BINDING AGENT
B-lymphocyte antigen CD19 binding agent
MEDI-551 binds directly to CD19 protein on the surface of the plasmablasts (produce autoantibodies called AQP4-Ab (or NMO-IgG) to the protein aquaporin-4 ) and depletes them.
- B-lymphocyte antigen CD19INHIBITOR
CD19 inhibitor
MEDI-551 binds directly to CD19 protein on the surface of the plasmablasts (produce autoantibodies called AQP4-Ab (or NMO-IgG) to the protein aquaporin-4 ) and depletes them.
CD19 other
Enhanced antibody-dependent cell-mediated cytotoxicity against B cells. Depletes mature B cells including plasmablasts and plasma cells with the added benefit of reducing serum Ab levels.
