Summary for Patent: 6,824,773
Title: TWEAK receptor
Abstract:The present invention provides the TWEAK receptor and methods for identifying and using agonists and antagonists of the TWEAK receptor. In particular, the invention provides methods of screening for agonists and antagonists and for treating diseases or conditions mediated by angiogenesis, such as solid tumors and vascular deficiencies of cardiac or peripheral tissue.
Inventor(s): Wiley; Steven R. (Seattle, WA)
Assignee: Immunex Corporation (Seattle, WA)
Application Number:09/742,454
Patent Claims:1. A method of inhibiting angiogenesis in a mammal in need of such treatment comprising administering a therapeutically-effective amount of a composition comprising an antagonist of a TWEAK receptor, wherein the TWEAK receptor comprises a sequence as set forth from amino acids 28-79 of SEQ ID No: 7, and the antagonist is selected from the group consisting of a soluble TWEAK receptor that comprises the cysteine-rich repeat and binds TWEAK, and an antibody that binds the TWEAK receptor.

2. The method of claim 1 wherein the composition further comprises a pharmaceutically acceptable carrier.

3. The method of claim 1 wherein the mammal is a human.

4. The method of claim 1 wherein the mammal has a disease or condition mediated by angiogenesis.

5. The method of claim 4 wherein the disease or condition is characterized by ocular neovascularization.

6. The method of claim 4 wherein the disease or condition is a malignant or metastatic condition.

7. The method of claim 6 wherein the malignant or metastatic condition is a solid tumor.

8. The method of claim 6 wherein the method further comprises treating the mammal with radiation.

9. The method of claim 6 wherein the method further comprises treating the mammal with a chemotherapeutic agent.

10. The method of claim 9 wherein the chemotherapeutic agent is selected from the group consisting of alkylating agents, antimetabolites, vinca alkaloid, plant-derived chemotherapeutics, nitrosoureas, antitumor antibiotics, antitumor enzymes, topoisomerase inhibitors, platinum analogs, adrenocortical suppressants, hormones, hormone agonists, hormone antagonists, antibodies, immunotherapeutics, blood cell factors, radiotherapeutics, and biological response modifiers.

11. The method of claim 9 wherein the chemotherapeutic agent is selected from the group consisting of cisplatin, cyclophosphamide, mechloretamine, melphalan, bleomycin, carboplatin, fluorouracil, 5-fluorodeoxyuridine, methotrexate, taxol, asparaginase, vincristine, vinblastine, lymphokines, cytokines, interleukins, interferons, alpha interferon, beta interferon, delta interferon, TNF, chlorambucil, busulfan, carmustine, lomustine, semustine, streptozocin, dacarbazine, cytarabine, mercaptopurine, thioguanine, vindesine, etoposide, teniposide, dactinomycin, daunorubicin, doxorubicin, plicamycin, mitomycin, L-asparaginase, hydroxyurea, methylhydrazine, mitotane, tamoxifen, and fluoxymesterone.

12. The method of claim 9 wherein the chemotherapeutic agent is selected from the group consisting of Flt3 ligand, CD40 ligand, interleukin-2, interleukin-12, 4-1BB ligand, anti-4-1BB antibodies, TNF antagonists, TNF receptor antagonists, TRAIL, CD148 agonists, VEGF antagonists, VEGF receptor antagonists, and Tek antagonists.

13. The method of claim 1 wherein the antagonist comprises an antibody that binds specifically to the TWEAK receptor extracellular domain.

14. The method of claim 13, wherein the antibody is selected from the group consisting of a monoclonal antibody, a humanized antibody, a transgenic antibody, and a human antibody.

15. The method of claim 13 wherein the antibody is conjugated to a radioisotope, a plant-derived toxin, a fungus-derived toxin, a bacterial-derived toxin, ricin A, diphtheria toxin, or a chemical poison.

16. The method of claim 13, wherein the mammal has a disease or condition mediated by angiogenesis.

17. The method of claim 16 wherein the disease or condition is characterized by ocular neovascularization.

18. The method of claim 16 wherein the disease or condition is a malignant or metastatic condition.

19. The method of claim 18 wherein the malignant or metastatic condition is a solid tumor.

20. The method of claim 18 wherein the method further comprises treating the mammal with radiation.

21. The method of claim 18 wherein the method further comprises treating the mammal with a chemotherapeutic agent.

22. The method of claim 21 wherein the chemotherapeutic agent is selected from the group consisting of alkylating agents, antimetabolites, vinca alkaloid, plant-derived chemotherapeutics, nitrosoureas, antitumor antibiotics, antitumor enzymes, topoisomerase inhibitors, platinum analogs, adrenocortical suppressants, hormones, hormone agonists, hormone antagonists, antibodies, immunotherapeutics, blood cell factors, radiotherapeutics, and biological response modifiers.

23. The method of claim 21 wherein the chemotherapeutic agent is selected from the group consisting of cisplatin, cyclophosphamide, mechloretamine, melphalan, bleomycin, carboplatin, fluorouracil, 5-fluorodeoxyuridine, methotrexate, taxol, asparaginase, vincristine, vinblastine, lymphokines, cytokines, interleukins, interferons, alpha interferon, beta interferon, delta interferon, TNF, chlorambucil, busulfan, carmustine, lomustine, semustine, streptozocin, dacarbazine, cytarabine, mercaptopurine, thioguanine, vindesine, etoposide, teniposide, dactinomycin, daunorubicin, doxorubicin, plicamycin, mitomycin, L-asparaginase, hydroxyurea, methylhydrazine, mitotane, tamoxifen, and fluoxymesterone.

24. The method of claim 21 wherein the chemotherapeutic agent is selected from the group consisting of Flt3 ligand, CD40 ligand, interleukin-2, interleukin-12, 4-1BB ligand, anti-4-1BB antibodies, TNF antagonists, TNF receptor antagonists, TRAIL, CD148 agonists, VEGF antagonists, VEGF receptor antagonists, and Tek antagonists.

25. The method of claim 1 wherein the antagonist disrupts the interaction between the TWEAK receptor and a TRAF molecule.
