 The humanized monoclonal antibody, AAB-001, which binds to and clears beta amyloid peptide, is designed to provide antibodies to beta amyloid directly to the patient, rather than requiring the patient to mount hisher own individual response. It is believed that this approach may eliminate the need for the patient to mount an immune response to beta amyloid. Animal studies have shown that this approach is equally effective in clearing beta amyloid from the brain as traditional active immunization methods.
