Abstract

Antibody molecules, in particular fully human antibodies that bind to human IGF-1 and cross-react with IGF-2 such that binding of IGF-1 and IGF-2 to the IGF-1 receptor is prevented and IGF-1 receptor-mediated signaling is inhibited. The antibodies do not bind to insulin and thus do not affect the mitogenic properties of insulin that are mediated by its binding to the insulin receptors. The antibodies are useful for the treatment of hyperproliferative diseases, in particular cancer.

First claim

The invention claimed is:

1. A pharmaceutical composition comprising an anti-IGF antibody molecule, wherein said antibody molecule has heavy chain CDRs comprising the amino acid sequences of SEQ ID NO:21 (CDR1), SEQ ID NO:22 (CDR2) and SEQ ID NO:23 (CDR3) and has light chain CDRs comprising the amino acid sequences of SEQ ID NO:24 (CDR1), SEQ ID NO:25 (CDR2) and SEQ ID NO:26 (CDR3),
and a pharmaceutically acceptable carrier, said pharmaceutical composition further comprising one or more additional therapeutic agents selected from:
a) DNA damaging agents,
b) therapeutically active compounds that inhibit signal transduction pathways or mitotic checkpoints in cancer cells, and
c) antidiabetics.

2. The pharmaceutical composition of claim 1 , wherein said one or more therapeutically active compounds in b) is selected from the group of inhibitors of EGFR, VEGF, HER2-neu, AuroraB, Plk1, PI3 kinase, and mTor.

3. The pharmaceutical composition of claim 1 , wherein said antibody molecule has a variable heavy chain comprising the amino acid sequence of SEQ ID NO:28 and a variable light chain comprising the amino acid sequence of SEQ ID NO:30.

4. The pharmaceutical composition of claim 1 , comprising a heavy chain constant region selected from the group consisting of IgG1, IgG2, IgG3, IgG4, IgM, IgA and IgE constant regions.

5. The pharmaceutical composition of claim 4 , wherein said heavy chain constant region is IgG1 comprising the amino acid sequence of SEQ ID NO:32.

6. The pharmaceutical composition of claim 1 , wherein the light chain constant region is Igλ.

7. The pharmaceutical composition claim 6 , wherein the light chain constant region comprises the amino acid sequence of SEQ ID NO:34.

8. The pharmaceutical composition of claim 1 , wherein said antibody molecule has a heavy chain comprising the amino acid sequence of SEQ ID NO:39 and a light chain comprising the amino acid sequence of SEQ ID NO:40.

9. The pharmaceutical composition of claim 1 , wherein said antibody molecule is a Fab, F(ab′) 2 , or single chain Fv fragment.

10. A pharmaceutical composition comprising an anti-IGF antibody molecule, wherein said antibody molecule has heavy chain CDRs comprising the amino acid sequences of SEQ ID NO:21 (CDR1), SEQ ID NO:22 (CDR2) and SEQ ID NO:23 (CDR3) and has light chain CDRs comprising the amino acid sequences of SEQ ID NO:24 (CDR1), SEQ ID NO:25 (CDR2) and SEQ ID NO:26 (CDR3), and a pharmaceutically acceptable carrier, said pharmaceutical composition further comprising cisplatin, oxaliplatin, carboplatin, lobaplatin, satraplatin, sorafenib, or a compound selected from the group of inhibitors of EGFR, VEGF, HER2-neu, AuroraB, Plk1, PI3 kinase, and mTor.

11. The pharmaceutical composition of claim 10 , said pharmaceutical composition further comprising either (a) carboplatin and paclitaxel or (b) cisplatin and gemcitabine.

12. The pharmaceutical composition of claim 10 , wherein said antibody molecule has a variable heavy chain comprising the amino acid sequence of SEQ ID NO:28 and a variable light chain comprising the amino acid sequence of SEQ ID NO:30.

13. The pharmaceutical composition of claim 10 , comprising a heavy chain constant region selected from the group consisting of IgG1, IgG2, IgG3, IgG4, IgM, IgA and IgE constant regions.

14. The pharmaceutical composition of claim 13 , wherein said heavy chain constant region is IgG1 comprising the amino acid sequence of SEQ ID NO:32.

15. The pharmaceutical composition of claim 10 , wherein the light chain constant region is Igλ.

16. The pharmaceutical composition claim 15 , wherein the light chain constant region comprises the amino acid sequence of SEQ ID NO:34.

17. The pharmaceutical composition of claim 10 , wherein said antibody molecule has a heavy chain comprising the amino acid sequence of SEQ ID NO:39 and a light chain comprising the amino acid sequence of SEQ ID NO:40.

18. The pharmaceutical composition of claim 10 , wherein said
antibody molecule is a Fab, F(ab′) 2 , or single chain Fv fragment.
