Title:Compositions and methods for treatment
Abstract: The present invention provides compounds and methods for the treatment of LFA-1 mediated diseases. In particular, LFA-1 antagonists are described herein and these antagonists are used in the treatment of LFA-1 mediated diseases. One aspect of the invention provides for diagnosis of an LFA-1 mediated disease and administration of a LFA-1 antagonist, after the patient is diagnosed with a LFA-1 mediated disease. In some embodiments, the LFA-1 mediated diseases treated are dry eye disorders. Also provided herein are methods for identifying compounds which are LFA-1 antagonists.

Assignee: SARcode Bioscience Inc. (Bisbane, CA)
Filing Date:Oct 03, 2013
Application Number:14/045,131
Claims:1. A method of treating dry eye disease in a subject in need thereof comprising administering to the subject an effective amount of a lymphocyte function associated antigen-1 (LFA-1) antagonist or a pharmaceutically acceptable salt or ester thereof, wherein the LFA-1 antagonist is ##STR00033##

2. The method of claim 1, wherein the subject does not have Sjogren's syndrome.

3. The method of claim 1, where the subject has Sjogren's syndrome.

4. The method of claim 1, wherein the administering comprises topical administration of the LFA-1 antagonist to the outer surface of the eyelid, lacrimal tissues, conjunctival tissue or ocular surface of the eye via a carrier vehicle selected from the group consisting of liquid drops, liquid wash, gel, ointment, spray, and liposome.

5. The method of claim 4, wherein the topical administration comprises infusion of the LFA-1 antagonist to an eye of the subject via a device selected from the group consisting of a pump-catheter system, a continuous or selective release system, and a contact lens.

6. The method of claim 1, wherein the administering involves systemically administering a liquid or liquid suspension of the LFA-1 antagonist via nose drops of nasal spray or nebulized liquid to oral or nasopharylngeal airways of the subject, such that an effective amount of the LFA-1 antagonist contacts one or more of a lacrimal gland, conjunctival tissue, tears, or ocular surface of an eye of the subject.

7. The method of claim 1, wherein the administering involves administering an oral form of the LFA-1 antagonist, such that an effective amount of the LFA-1 antagonist contacts one or more of the lacrimal gland, conjunctival tissue, tears, or ocular surface of the eye of the subject via systemic absorption and circulation.

8. The method of claim 1, wherein the administering is accomplished by administering an injectable form of the LFA-1 antagonist, such that an effective amount of the LFA-1 antagonist contacts one or more of the lacrimal tissues, conjunctival tissue, tears, or ocular surface of the eye of the subject via systemic absorption and circulation.

9. The method of claim 1, wherein the administering is accomplished by administering a suppository form of the LFA-1 antagonist, such that an effective amount of the LFA-1 antagonist contacts one or more of the lacrimal tissues, conjunctival tissue, tears, or ocular surface of the eye of the subject via systemic absorption and circulation.

10. The method of claim 1, wherein the administering is accomplished by administering an intraocular instillation of a gel, cream, powder, foam, crystals, liposomes, spray or liquid suspension form of the LFA-1 antagonist .

11. The method of claim 1, wherein the LFA-1 antagonist is administered to the ocular surfaces of the subject in an amount sufficient to achieve concentrations thereof of from about 1.times.10.sup.-7 to about 1.times.10.sup.-1 moles/liter.

12. The method of claim 1, wherein the administering is via a sustained release insert or implant, subconjunctival injection, intraocular injection, periocular injection, retrobulbar injection, or intracameral injection.

13. The method of claim 1, wherein the administering involves delivery of a liquid or liquid suspension of the LFA-1 antagonist via nose drops or nasal spray or nebulized liquid to oral or nasopharyngeal airways of the subject, such that an effective amount of said compound contacts one or more of the lacrimal gland, conjunctival tissue, or ocular surface of the eye of the LFA-1 antagonist via nasolacrimal ducts.

14. The method of claim 1, wherein the administering is accomplished by administering an injectable form of the LFA-1 antagonist, such that a therapeutically effective amount of the LFA-1 antagonist contacts one or more of the lacrimal tissues, conjunctival tissue or ocular surface of the eye of the subject via local delivery.

15. The method of claim 5, wherein the continuous or selective release device is an ocular insert or implant.

16. The method of claim 5, wherein an effective amount of the LFA-1 antagonist is distributed regionally to one or more of a nose, nasal passages, and nasal cavity of the subject.

17. The method of claim 1, wherein the administering comprises controlled release of the LFA-1 antagonist from a biocompatible polymer.

18. A method of treating dry eye disorder in a subject in need thereof comprising administering to an eye of the subject an effective amount of a pharmaceutical composition comprising a LFA-1 antagonist or a pharmaceutically acceptable salt or ester thereof, wherein the LFA-1 antagonist is ##STR00034## and whereby the administering is effective in promoting tear secretion or mucin production in said eyes in said subject.

19. A method of treating dry eye disease in a subject comprising performing a dry eye diagnostic test on the subject; determining whether the subject suffers from a dry eye disease based on the results of the diagnostic step; and upon diagnosis of the dry eye disease, administering to the subject an effective amount of a LFA-1 antagonist or a pharmaceutically acceptable salt or ester thereof, wherein the LFA-1 antagonist is ##STR00035##

20. A method of treating dry eye disorder in a subject in need thereof comprising administering to an eye of the subject a therapeutically effective amount of a pharmaceutical composition comprising an LFA-1 antagonist and/or its pharmaceutically acceptable salts or ester, wherein said LFA-1 antagonist is ##STR00036## wherein the administering comprising administering the LFA-1 antagonist in liquid drops topically to a surface of the subject's eyes.
