Abstract

The present invention relates to soluble and stable anti-VEGF imunobinders comprising CDRs from rabbit monoclonal antibodies. Said antibodies are designed for the diagnosis and/or treatment of VEGF-mediated disorders. The hybridomas, nucleic acids, vectors and host cells for expression of the recombinant antibodies of the invention, methods for isolating them and the use of said antibodies in medicine are also disclosed.

Claims (12)

1 . A method of treating a VEGF-mediated disease in a subject, comprising administering to the subject in need thereof a humanized antibody or antigen-binding fragment thereof, the humanized antibody comprising a variable heavy chain (VH), and a variable light chain (VL), wherein: the VH comprises CDRH1, CDRH2 and CDRH3 sequences of SEQ ID NO: 8, SEQ ID NO: 20 and SEQ ID NO: 32, respectively, and the VL comprises CDRL1, CDRL2, and CDRL3 sequences of SEQ ID NO: 43, SEQ ID NO: 55 and SEQ ID NO: 66, respectively, wherein the antibody or antigen-binding fragment thereof binds human VEGF 165 with an affinity (K d ) of ≤1×10 −9 M, and wherein the VEGF-mediated disease is age-related macular degeneration (AMD).

2 . The method of claim 1 , wherein the fragment is an scFv, a Fab fragment, a Fab′ fragment, or a F(ab′)2 fragment.

3 . The method of claim 1 , wherein the fragment is an scFv.

4 . The method of claim 1 , wherein the humanized antibody or antigen-binding fragment comprises a heavy chain variable region having at least 95% sequence identity to the sequence of SEQ ID NO: 164.

5 . The method of claim 4 , wherein the humanized antibody or antigen-binding fragment comprises a heavy chain variable region having the sequence of SEQ ID NO: 164.

6 . The method of claim 1 , wherein the humanized antibody or antigen-binding fragment comprises a light chain variable region having at least 95% sequence identity to the sequence of SEQ ID NO: 87.

7 . The method of claim 6 , wherein the humanized antibody or antigen-binding fragment comprises a light chain variable region having the sequence of SEQ ID NO: 87.

8 . The method of claim 1 , wherein the fragment is an scFv and wherein the heavy chain variable region and the light chain variable region are linked by the sequence of SEQ ID NO: 181.

9 . The method of claim 1 , wherein the humanized antibody or antigen-binding fragment comprises a heavy chain variable region having at least 90% sequence identity to the sequence of SEQ ID NO: 164.

10 . The method of claim 1 , wherein the humanized antibody or antigen-binding fragment comprises a light chain variable region having at least 90% sequence identity to the sequence of SEQ ID NO: 87.

11 . The method of claim 1 , wherein the humanized antibody or antigen-binding fragment thereof is formulated for intraocular administration.

12 . The method of claim 3 , wherein the antigen-binding fragment is administered and formulated for intraocular administration.
