Abstract: This invention provides novel chimeric molecules that specifically binds a tumor cell bearing a c-erbB-2. The chimeric molecules comprise an effector molecule attached to a C6 antibody that specifically binds to c-erbB-2. The chimeric molecules can specifically target and deliver effector molecules to cells overexpressing c-erb-B2.

Abstract: This invention provides novel human antibodies that specifically bind to human c-erbB-2. In one embodiment, the antibodies are single chain antibodies initially developed by phage display against a c-erbB-2 target. The resulting antibodies (designated C6 antibodies) show improved specificity and affinity for c-erbB-2. In addition, since the C6 antibodies are both relatively small and fully human they are less immunogenic in humans than other (e.g., full-size or chimeric) anti-c-erbB-2 antibodies. The C6 antibodies may be used alone or as components of chimeric molecules that specifically target and deliver effector molecules to cells overexpressing c-erbB-2.
