Abstract

The invention features methods and compositions for preventing or treating bone cancer pain including cancer pain associated with bone metastasis by administering an antagonist of nerve growth factor (NGF). The NGF antagonist may be an anti-NGF (such as anti-hNGF) antibody that is capable of binding hNGF.

Claims

1. A method for treating bone cancer pain in an individual comprising administering to the individual an effective amount of an anti-nerve growth factor (NGF) antagonist antibody, wherein the anti-NGF antagonist antibody comprises:

a heavy chain variable region (VH) comprising a VH CDR1, VH CDR2, and VH CDR3 of the VH sequence shown in SEQ ID NO;

1; and

a light chain variable region (VL) comprising a VL CDR1, VL CDR2, and VL CDR3 of the VL sequence shown in SEQ ID NO;

2.

2. The method of claim 1, wherein the VH CDR1, VH CDR2, and VH CDR3 of the anti-NGF antagonist antibody are Kabat, Chothia, or a combination of Kabat and Chothia CDRs of the VH sequence shown in SEQ ID NO:

1.

3. The method of claim 1, wherein the VH region comprises the amino acid sequence shown in SEQ ID NO:

1 or a variant with one or several conservative amino acid substitutions in residues that are not within a CDR and the VL region comprises the amino acid sequence shown in SEQ ID NO;

2 or a variant thereof with one or several amino acid substitutions in amino acids that are not within a CDR.

4. The method of claim 2, wherein the bone cancer pain is from cancer originated in bone.

5. The method of claim 2, wherein the bone cancer pain is from osteosarcoma.

6. The method of claim 2, wherein the bone cancer pain is from cancer metastasized to bone.

7. The method of claim 2, wherein the bone cancer pain is from prostate cancer metastasized to bone.

8. The method of claim 2, wherein the bone cancer pain is from breast cancer metastasized to bone.

9. The method of claim 2, wherein the bone cancer pain is from lung cancer metastasized to bone.

10. The method of claim 2, wherein the bone cancer pain is from sarcoma metastasized to bone.
