Oncostatin M receptor antigen binding proteins
The invention provides anti-oncostatin M receptor-β (OSMR) antigen binding proteins. e.g., antibodies and functional fragments, derivatives, muteins, and variants thereof. OSMR antigen binding proteins interfere with binding of OSM and/or IL-31 to OSMR. In some embodiments, anti-OSMR antigen binding proteins are useful tools in studying diseases and disorders associated with OSMR and are particularly useful in methods of treating diseases and disorders associated with OSMR and binding of OSM and/or IL-31 to OSMR.
1. A method of treating pruritis, said method comprising administering a therapeutically effective amount of an anti-oncostatin M receptor (OSMR) antibody to a patient in need thereof, wherein the anti-OSMR antibody comprises:
a light chain variable domain comprising a light chain complementary-determining region 1 (LCDR1) defined by SEQ ID NO:31, a light chain complementary-determining region 2 (LCDR2) defined by SEQ ID NO:34, and a light chain complementary-determining region 3 (LCDR3) defined by SEQ ID NO:37; and
a heavy chain variable domain comprising a heavy chain complementary-determining region 1 (HCDR1) defined by SEQ ID NO:13, a heavy chain complementary-determining region 2 (HCDR2) defined by SEQ ID NO:16, and a heavy chain complementary-determining region 3 (HCDR3) defined by SEQ ID NO:19.
2. The method of claim 1 , wherein the light chain variable domain has the amino acid sequence set forth in SEQ ID NO:28.
3. The method of claim 1 , wherein the heavy chain variable domain has the amino acid sequence set forth in SEQ ID NO:54.
4. The method of claim 1 , wherein:
the light chain variable domain has the amino acid sequence set forth in SEQ ID NO:28; and
the heavy chain variable domain has the amino acid sequence set forth in SEQ ID NO:54.
5. The method of claim 1 , wherein the light chain of the antibody comprises the amino acid sequence set forth in SEQ ID NO:25.
6. The method of claim 1 , wherein the antibody is a monoclonal antibody.
7. The method of claim 6 , wherein the antibody is a human antibody.
8. The method of claim 1 , wherein the antibody inhibits binding of human oncostatin M (OSM) or human interleukin 31 to human OSMR.
9. The method of claim 1 , wherein the antibody reduces human OSM-mediated or human interleukin 31-mediated OSMR signaling in human OSMR-expressing cells.
10. The method of claim 4 , wherein the antibody is a monoclonal antibody.
11. The method of claim 10 , wherein the antibody is a human antibody.
12. The method of claim 4 , wherein the light chain of the antibody comprises the amino acid sequence set forth in SEQ ID NO:25.
13. The method of claim 4 , wherein the antibody inhibits binding of human OSM or human interleukin 31 to human OSMR.
14. The method of claim 4 , wherein the antibody reduces human OSM-mediated or human interleukin 31-mediated OSMR signaling in human OSMR-expressing cells.
15. The method of claim 1 , wherein administering a therapeutically effective amount of the anti-OSMR antibody comprises intravenous delivery or subcutaneous delivery.
16. The method of claim 4 , wherein administering a therapeutically effective amount of the anti-OSMR antibody comprises intravenous or subcutaneous delivery.
