A monoclonal antibody against amyloid with potential use in the treatment of amyloid light chain (AL) and AA amyloidosis. Upon intravenous administration, anti-amyloid monoclonal antibody NEOD001 specifically binds to amyloid fibrils. This prevents the formation of amyloid deposits in certain organs and facilitates their clearance. It also reduces the level of amyloid deposits in organs and prevents organ dysfunction.
