Summary for Patent: 9,073,997
Title:Growth factor antagonists for organ transplant alloimmunity and arteriosclerosis
Abstract: The present invention provides materials and methods for antagonizing the function of vascular endothelial growth factor receptors, platelet derived growth factor receptors and other receptors, to prevent, inhibit, or ameliorate allograft rejection or arteriosclerosis in organisms that receive an organ transplant.
Inventor(s): Alitalo; Kari (Helsinki, FI), Lemstrom; Karl B. (Helsinki, FI), Nykanen; Antti I. (Helsinki, FI)
Assignee: VEGENICS PTY LIMITED (South Yarra, Victoria, AU)
Application Number:12/024,454
Patent Claims:1. A method for inhibiting rejection of a vascularized tissue or vascularized organ transplant, or for inhibiting arteriosclerosis in a human allograft transplant recipient, comprising: administering to a human allograft transplant recipient a composition that comprises an endothelial growth factor inhibitor in an amount effective to inhibit rejection, or inhibit arteriosclerosis, wherein the endothelial growth factor inhibitor comprises a compound that inhibits stimulation of human VEGFR-3 by VEGF-C or inhibits stimulation of human VEGFR-3 by VEGF-D, and wherein the compound comprises an antibody that immunoreacts with human VEGFR-3.

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

3. The method of claim 1, where the transplant is a vascularized tissue transplant.

4. The method of claim 1, wherein the vascularized organ transplant is an organ or organ fragment capable of performing functions of the organ or capable of regenerating into the organ.

5. A method for inhibiting rejection of a transplanted organ, or fragment thereof, the organ selected from the group consisting of a heart, a kidney, a lung, a liver, an intestine, a pancreas, skin, and bone, the method comprising: administering to a human transplant recipient a composition that comprises an endothelial growth factor inhibitor in an amount effective to inhibit rejection, wherein the endothelial growth factor inhibitor comprises a compound that inhibits stimulation of human VEGFR-3 by VEGF-C or inhibits stimulation of human VEGFR-3 by VEGF-D, and wherein the compound comprises an antibody that immunoreacts with human VEGFR-3.

6. The method of claim 1, wherein the organ is selected from the group consisting of a heart, a lung, a liver, and a kidney.

7. The method of claim 1, wherein the organ is a heart.

8. The method of claim 1, wherein the composition is administered locally to the transplanted vascularized tissue or vascularized organ in the recipient.

9. The method of claim 1, wherein the composition is administered systemically to the recipient.

10. The method of claim 1, wherein the composition is administered intravenously, intramuscularly, or intraperitoneally.

11. The method of claim 1, wherein the composition is administered perorally.

12. The method of claim 1, further comprising administering the composition to the organ or the organ donor before the transplant.

13. The method of claim 1, further comprising repeated administration of the composition to the recipient.

14. The method of claim 1, wherein the composition is administered to the recipient perioperatively, relative to the transplant operation.

15. The method of claim 1, wherein the composition is administered to the recipient for 1-90 days post-operatively, relative to the transplant operation.

16. The method of claim 1, wherein the composition is administered to the recipient for 1-60 days post-operatively, relative to the transplant operation.

17. The method of claim 1, wherein the composition is administered to the recipient for 1-30 days post-operatively, relative to the transplant operation.

18. The method of claim 1, wherein the composition is administered to the recipient for 1-15 days post-operatively, relative to the transplant operation.

19. The method of claim 1, comprising: screening the recipient for symptoms of an acute rejection reaction; and administering the composition to the recipient upon detection of symptoms of acute rejection, in an amount effective to inhibit the rejection.

20. The method of claim 1, wherein the antibody is selected from the group consisting of a humanized antibody, a human antibody, a monoclonal antibody, an antigen binding fragment thereof, and a polypeptide that comprises an antigen binding fragment of an antibody.

21. The method of claim 1, further comprising administering to the recipient a composition that comprises at least one growth factor inhibitor selected from the group consisting of: inhibitors of VEGFR-1; inhibitors of VEGFR-2; inhibitors of PDGFR-alpha; and inhibitors of PDGFR-beta; wherein the combination of inhibitors are administered in amounts effective to inhibit rejection, or inhibit arteriosclerosis.

22. The method of claim 1, further comprising administering an immunosuppressive agent to the recipient, wherein the immunosuppressive agent comprises at least one compound selected from the group consisting of: Tacrolimus, Mycophenolic acid, Prednisone, cyclosporine, Azathioprine, Basiliximab, Daclizumab, Muromonab-CD3, Mycophenolate Mofetil, Sirolimus, Methylprednisolone, Thymoglobulin, OKT3, Rapamycin, and Interleukin-2 Receptor Antagonist.

23. The method of claim 1, further comprising administering an antibiotic or antifungal agent to the recipient.

24. The method of claim 1, further comprising administering to a human donor organism a composition that comprises an endothelial growth factor inhibitor, prior to harvesting a vascularized tissue or vascularized organ for transplantation into the recipient.

25. The method of claim 1, further comprising contacting a vascularized tissue or vascularized organ with a composition that comprises an endothelial growth factor inhibitor, prior to transplanting the vascularized tissue or vascularized organ into the recipient.

26. The method of claim 1, further comprising administering to a donor organism, prior to harvesting a vascularized tissue or vascularized organ for transplantation, a composition that comprises a nucleic acid that comprises a nucleotide sequence that encodes an endothelial growth factor inhibitor, wherein the nucleic acid is expressible in cells of the tissue or vascularized organ to be transplanted.

27. The method of claim 1, further comprising contacting a vascularized tissue or vascularized organ with a composition that comprises a nucleic acid that comprises a nucleotide sequence that encodes an endothelial growth factor inhibitor, prior to transplanting the vascularized tissue or vascularized organ into the recipient.

28. The method of claim 22, further comprising administering an antibiotic or antifungal agent to the recipient.

29. The method of claim 22, further comprising administering to a human donor organism a composition that comprises an endothelial growth factor inhibitor, prior to harvesting a vascularized tissue, or vascularized organ for transplantation into the recipient.

30. The method of claim 28, further comprising administering to a donor organism a composition that comprises an endothelial growth factor inhibitor, prior to harvesting a vascularized tissue, or vascularized organ for transplantation into the recipient.
