Abstract

Compositions and methods for inducing pterygium regression from visual axis/central cornea, stabilizing pterygium, treating hyperemia and symptoms in pterygium patients, and treating pterygium recurrence following pterygiectomy are disclosed. The methods include administration of a multikinase inhibitor, an antimetabolite or a combination thereof to patients in need thereof.

Claims (24)

1. A method for inducing regression of a pterygium from the central cornea of an affected eye without surgically excising the pterygium, comprising administering to the affected eye of a subject in need of such treatment a therapeutically effective amount of a multikinase inhibitor.

2. The method of claim 1 , wherein the multikinase inhibitor reduces the kinase activity of one or more intracellular and/or cell surface protein kinases selected from EGFR, ErbB2, ErbB3, FGFR1, TrkA, NGFR, VEGFR (1, 2, 3), PDGFR (α, β), TGF-βR (I, II, III), FLT3, c-Kit, RET, CSF-1R in the pterygium.

3. The method of claim 1 , wherein the multikinase inhibitor is selected from the group consisting of Afatinib, Amuvatinib, Axitinib, Cabozantinib, Canertinib, Cediranib, Ceritinib, Crenolanib, Crizotinib, Dabrafenib, Dacomitinib, Dasatinib, Erlotinib, Foretinib, Gefitinib, Golvatinib, Ibrutinib, Icotinib, Idelalisib, Imatinib, Lapatinib, Lenvatinib, Neratinib, Nilotinib, Nintedanib, Palbociclib, Pazopanib, Ponatinib, Quizartinib, Regorafenib, Ruxolitinib, Sorafenib, Sunitinib, Tandutinib, Tivantinib, Tivozanib, Trametinib, Vandetanib, Vatalanib, and Vemurafenib.

4. The method of claim 1 , further comprising administering to the affected eye subject in need of such treatment a therapeutically effective amount of an antimetabolite is selected from the group consisting of Mitomycin C, 5-Fluorouracil, and Thiotepa.

5. The method of claim 1 , wherein the multikinase inhibitor is administered to the affected eye in the form of a topical ocular formulation or an ocular implant.

6. The method of claim 5 , wherein the multikinase inhibitor is administered topically to the affected eye in the form of a topical ocular formulation.

7. The method of claim 1 , wherein the multikinase inhibitor is Nintedanib.

8. The method of claim 1 , further comprising identifying a patient seeking to avoid or delay pterygium surgery as the subject in need prior to administering the multikinase inhibitor.

9. A method for stabilizing a pterygium in an affected eye without surgically excising the pterygium, comprising administering to the affected eye of a subject in need of such treatment a therapeutically effective amount of a multikinase inhibitor.

10. The method of claim 9 , wherein the multikinase inhibitor reduces the activity of one or more intracellular and/or cell surface protein kinases selected from EGFR, ErbB2, ErbB3, FGFR1, TrkA, NGFR, VEGFR (1, 2, 3), PDGFR (α, β), TGF-βR (I, II, III), FLT3, c-Kit, RET, CSF-1R in the pterygium.

11. The method of claim 9 , wherein the multikinase inhibitor is selected from the group consisting of Afatinib, Amuvatinib, Axitinib, Cabozantinib, Canertinib, Cediranib, Ceritinib, Crenolanib, Crizotinib, Dabrafenib, Dacomitinib, Dasatinib, Erlotinib, Foretinib, Gefitinib, Golvatinib, Ibrutinib, Icotinib, Idelalisib, Imatinib, Lapatinib, Lenvatinib, Neratinib, Nilotinib, Nintedanib, Palbociclib, Pazopanib, Ponatinib, Quizartinib, Regorafenib, Ruxolitinib, Sorafenib, Sunitinib, Tandutinib, Tivantinib, Tivozanib, Trametinib, Vandetanib, Vatalanib, and Vemurafenib.

12. The method of claim 9 , further comprising administering to the affected eye subject in need of such treatment a therapeutically effective amount of an antimetabolite selected from the group consisting of Mitomycin C, 5-Fluorouracil, and Thiotepa.

13. The method of claim 9 , wherein the multikinase inhibitor is administered to the affected eye in the form of a topical ocular formulation or an ocular implant.

14. The method of claim 13 , wherein the multikinase inhibitor is administered topically to the affected eye in the form of a topical ocular formulation.

15. The method of claim 9 , wherein the multikinase inhibitor is Nintedanib.

16. The method of claim 9 , further comprising identifying a patient seeking to avoid or delay pterygium surgery as the subject in need prior to administering the multikinase inhibitor.

17. A method for reducing the rate of growth of a pterygium in an affected eye without surgically excising the pterygium, comprising administering to an affected eye of a subject in need of such treatment a therapeutically effective amount of a multikinase inhibitor.

18. The method of claim 17 , wherein the multikinase inhibitor reduces the activity of one or more intracellular and/or cell surface protein kinases selected from EGFR, ErbB2, ErbB3, FGFR1, TrkA, NGFR, VEGFR (1, 2, 3), PDGFR (α, β), TGF-βR (I, II, III), FLT3, c-Kit, RET, CSF-1R in the pterygium.

19. The method of claim 17 , wherein the multikinase inhibitor is selected from the group consisting of Afatinib, Amuvatinib, Axitinib, Cabozantinib, Canertinib, Cediranib, Ceritinib, Crenolanib, Crizotinib, Dabrafenib, Dacomitinib, Dasatinib, Erlotinib, Foretinib, Gefitinib, Golvatinib, Ibrutinib, Icotinib, Idelalisib, Imatinib, Lapatinib, Lenvatinib, Neratinib, Nilotinib, Nintedanib, Palbociclib, Pazopanib, Ponatinib, Quizartinib, Regorafenib, Ruxolitinib, Sorafenib, Sunitinib, Tandutinib, Tivantinib, Tivozanib, Trametinib, Vandetanib, Vatalanib, and Vemurafenib.

20. The method of claim 17 , further comprising administering to the affected eye subject in need of such treatment a therapeutically effective amount of an antimetabolite selected from the group consisting of Mitomycin C, 5-Fluorouracil, and Thiotepa.

21. The method of claim 17 , wherein the multikinase inhibitor is administered to the affected eye in the form of a topical ocular formulation or an ocular implant.

22. The method of claim 21 , wherein the multikinase inhibitor is administered topically to the affected eye in the form of a topical ocular formulation.

23. The method of claim 17 , wherein the multikinase inhibitor is Nintedanib.

24. The method of claim 17 , further comprising identifying a patient seeking to avoid or delay pterygium surgery as the subject in need prior to administering the multikinase inhibitor.
