CAI-based systems and methods for the localized treatment of uveitis
This invention relates to the treatment of uveitis, in particular posterior infectious uveitis. In specific embodiments, the invention provides for methods of treating uveitis and/or infectious uveitis comprising administration of a sustained-release system containing 5-amino-[4-(4-chlorobenzoyl)-3,5-dichlorobenzyl]-1,2,3-triazole-4-carboxamide) and optionally a glucocorticoid. In one embodiment, the glucocorticoid is dexamethasone. In another embodiment, the sustained-release system comprises a polymer such as e.g. polylactic-coglycolic acid.
1. A method of treating parasite induced posterior infectious uveitis in a patient comprising administering to the patient a sustained-release system comprising a pharmaceutically effective amount of 5-amino-[4-(4-chlorobenzoyl)-3,5-dichlorobenzyl]-1,2,3-triazole-4-carboxamide) (CAI).
2. The method of claim 1 , wherein the sustained-release system comprises a polymer.
3. The method of claim 2 , wherein the polymer degrades over time.
4. The method of claim 3 , wherein the polymer comprises polylactic-coglycolic acid (PLGA).
5. The method of claim 1 , wherein the sustained release system comprises a non-erodible intravitreal implant.
6. The method of claim 1 , wherein the posterior infectious uveitis is caused by toxoplasmosis, toxocara or visceral larva migrans.
7. The method of claim 1 , wherein the sustained-release system further comprises one or more of an anti-inflammatory agent, a steroid and/or an antibacterial agent.
8. The method of claim 7 , wherein the steroid is a glucocorticoid or fluocinolone acetonide.
9. The method of claim 8 , wherein the glucocorticoid comprises dexamethasone.
10. The method of claim 1 , wherein CAI is a sonicated microparticle or in a molecular complex in formulation with hydroxypropyl β-cyclodextrin.
11. A method of treating parasite induced posterior infectious uveitis in a patient comprising administering a sustained-release system comprising a pharmaceutically effective amount of 5-amino-[4-(4-chlorobenzoyl)-3,5-dichlorobenzyl]-1,2,3-triazole-4-carboxamide) and a steroid to a patient.
12. The method of claim 11 , wherein the steroid is a glucocorticoid or fluocinolone acetonide.
13. The method of claim 11 , wherein the sustained-release system comprises a polymer.
14. The method of claim 13 , wherein the polymer comprises polylactic-coglycolic acid (PLGA).
15. The method of claim 11 , wherein the steroid comprises dexamethasone.
16. The method of claim 11 , wherein the sustained-release system further comprises an anti-inflammatory agent and/or an anti-bacterial agent.
17. The method of claim 13 , wherein the polymer degrades over time.
18. The method of claim 11 , wherein CAI is a sonicated microparticle or in a molecular complex in formulation with hydroxypropyl β-cyclodextrin.
19. The method of claim 11 , wherein the sustained release system comprises a non-erodible intravitreal implant.
20. The method of claim 11 , wherein the posterior infectious uveitis is caused by toxoplasmosis, toxocara or visceral larva migrans.
21. The method of claim 9 , wherein the amount of dexamethasone is from about 0.5 to about 0.9 mg.
