Amphiregulin antibodies and their use to treat cancer and psoriasis
View Patent ↗The present invention is directed to anti-AR antibodies, preferably humanized monoclonal antibodies having the amino acid sequences disclosed herein. The present invention includes a pharmaceutical composition comprising such antibodies. The present invention includes a method of inhibiting cancer cell growth comprising administering such antibodies into a subject. The present invention also provides a method of treating cancer or psoriasis in a subject in need of such a treatment by administering such antibodies to said subject in a pharmaceutically effective amount.
1. A chimeric, humanized or human antibody that specifically binds to amphiregulin (AR) comprising a heavy chain variable region defined by SEQ ID NO: 2 and a light chain variable region defined by SEQ ID NO: 3.
2. A chimeric, humanized or human antibody that specifically binds to amphiregulin (AR) comprising a heavy chain variable region defined by SEQ ID NO: 4 and a light chain variable region defined by SEQ ID NO: 5.
3. A chimeric, humanized or human antibody that specifically binds to amphiregulin (AR) comprising a heavy chain variable region defined by SEQ ID NO: 12 and a light chain variable region defined by SEQ ID NO: 14.
4. The antibody of claim 3 , wherein the antibody is an antigen binding fragment that is selected from the group consisting of Fab, Fab′, F(ab′) 2 , Fv fragments, rIgG, diabodies, single chain antibodies, and multispecific antibodies.
5. The antibody of claim 3 , wherein the antibody is conjugated to an effector moiety.
6. A pharmaceutical composition comprising the antibody of claim 3 and a pharmaceutically acceptable excipient.
