Summary for Patent: 10,100,115
Title:Methods for the treatment of vascularizing cancers
Abstract: The invention concerns therapeutic compositions for the treatment of vascularizing cancers, especially, glioblastoma. In particular, the invention is directed to compositions that comprise a molecule having a binding ability that is specific for B7-H3 and a molecule having a binding ability that is specific for a cell-surface factor (or its receptor) that is involved in promoting tumor angiogenesis (especially VEGF or its receptor, VEGFR). The invention is additionally directed to the use of such compositions in the treatment of such cancers, and in particular, in the treatment of glioblastoma.
Inventor(s): Chi; Andrew S. (Boston, MA)
Assignee: MacroGenics, Inc. (Rockville, MD)
Application Number:15/118,010
Patent Claims:1. A method of treating glioblastoma comprising administering to a recipient patient in need thereof[1,1]: a) an antibody, an antibody fragment thereof, or a diabody that specifically binds B7-H3, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 comprises: (1) a light chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 7), CDR.sub.2 (SEQ ID NO: 9) and CDR.sub.3 (SEQ ID NO: 11), and a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 15), CDR.sub.2 (SEQ ID NO: 17) and CDR.sub.3 (SEQ ID NO: 19); or (2) a light chain variable domain that comprises CDR.sub.! (SEQ ID NO: 23), CDR.sub.2 (SEQ ID NO: 25) and CDR.sub.3 (SEQ ID NO: 27), and a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 31), CDR.sub.2 (SEQ ID NO: 33) and CDR.sub.3 (SEQ ID NO: 35); or (3) a light chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 39), CDR.sub.2 (SEQ ID NO: 41) and CDR.sub.3 (SEQ ID NO: 43), and a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 47), CDR.sub.2 (SEQ ID NO: 49) and CDR.sub.3 (SEQ ID NO: 51); and b) an antibody, or an antibody fragment thereof that specifically binds VEGF or VEGFR; wherein said glioblastoma is characterized by cancer cells that express B7-H3.

2. The method of claim 1, wherein said antibody, or antibody fragment thereof that specifically binds VEGF or VEGFR is: (A) a VEGF antagonist; or (B) a VEGFR antagonist.

3. The method of claim 1, wherein said antibody, or antibody fragment thereof, that specifically binds VEGF or VEGFR: A. competes for VEGF binding with bevacizumab; or B. has the three heavy chain CDRs and the three light chain CDRs of bevacizumab.

4. The method of claim 1, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 is an anti-B7-H3 antibody having: (A) a light chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 39), CDR.sub.2 (SEQ ID NO: 41) and CDR.sub.3 (SEQ ID NO: 43) of the light chain of BRCA84D; (B) a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 47), CDR.sub.2 (SEQ ID NO: 49) and CDR.sub.3 (SEQ ID NO: 51) of the heavy chain of BRCA84D; and (C) an Fc region that comprises the substitutions: L235V, F243L, R292P, Y300L, and P396L.

5. The method of claim 4, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 is a humanized anti-B7-H3 antibody that comprises: (A) a variable light chain having the amino acid sequence of hBRCA84D-2 VL (SEQ ID NO:69); and (B) a variable heavy chain having the amino acid sequence of hBRCA84D-2 VH (SEQ ID NO:79); and said antibody, or antibody fragment thereof, that specifically binds VEGF or VEGFR is bevacizumab.

6. The method of claim 1, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 and said antibody, or antibody fragment thereof, that specifically binds VEGF or VEGFR are administered to said patient concurrently.

7. The method of claim 1, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 and said antibody, or antibody fragment thereof, that specifically binds VEGF or VEGFR are administered to said patient sequentially, wherein the second of said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3, or said antibody, or antibody fragment thereof, that specifically binds VEGF or VEGFR is administered to said patient within 5 half-lives after the administration of the first of said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3, or said antibody, or antibody fragment thereof, that specifically binds VEGF or VEGFR.

8. The method of claim 1, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 comprises a light chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 7), CDR.sub.2 (SEQ ID NO: 9) and CDR.sub.3 (SEQ ID NO: 11), and a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 15), CDR.sub.2 (SEQ ID NO: 17) and CDR.sub.3 (SEQ ID NO: 19).

9. The method of claim 1, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 comprises a light chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 23), CDR.sub.2 (SEQ ID NO: 25) and CDR.sub.3 (SEQ ID NO: 27), and a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 31), CDR.sub.2 (SEQ ID NO: 33) and CDR.sub.3 (SEQ ID NO: 35).

10. The method of claim 1, wherein said antibody, antibody fragment thereof, or diabody that specifically binds B7-H3 comprises a light chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 39), CDR.sub.2 (SEQ ID NO: 41) and CDR.sub.3 (SEQ ID NO: 43), and a heavy chain variable domain that comprises CDR.sub.1 (SEQ ID NO: 47), CDR.sub.2 (SEQ ID NO: 49) and CDR.sub.3 (SEQ ID NO: 51).
