Monoclonal antibodies to basic fibroblast growth factor
The present invention is directed toward a neutralizing monoclonal antibody to basic fibroblast growth factor, a pharmaceutical composition comprising same, and methods of treatment comprising administering such a pharmaceutical composition to a patient.
1. A mouse, chimeric or humanized form of a mAb produced by the PTA-8864 hybridoma.
2. A humanized antibody comprising a humanized light chain comprising the three light chain CDRs from the sequence in FIG. 11A (GAL-F2) (SEQ ID NO:1) and a humanized heavy chain comprising the three heavy chain CDRs from the sequence of FIG. 11B (GAL-F2) (SEQ ID NO:4).
3. The humanized antibody of claim 2 , wherein residues H1, H27, H30, H48, H67, H71 and H94 by Kabat numbering are occupied by the residue occupying the corresponding position of the heavy chain shown in FIG. 11B (GAL-F2) (SEQ ID NO:4).
4. The humanized antibody of claim 2 wherein the light chain variable region has at least 95% sequence identity to the sequence shown in FIG. 11A (HuGAL-F2) (SEQ ID NO:2) and the heavy chain has at least 95% sequence identity to the sequence shown in FIG. 11B (HuGAL-F2) (SEQ ID NO:5).
5. The humanized antibody of claim 4 , wherein the light chain variable region has the sequence shown in FIG. 11A (HuGAL-F2) (SEQ ID NO:2) and the heavy chain has the sequence shown in FIG. 11B (HuGAL-F2) (SEQ ID NO:5).
