SiteOne Therapeutics Announces Abstract Presentation at the Association for Research in Vision and Opthamology

BOZEMAN, Montana - SiteOne Therapeutics, Inc., today announced a presentation at the Association for Research in Vision and Opthalmology (ARVO) meeting in Honolulu, Hawaii, April 29 to May 3, 2018. 

The abstract will present preclinical research using SiteOne’s novel sodium ion channel blockers showing corneal anesthesia, penetration into the ocular structures, and excellent tolerability after topical administration.  The study was conducted to inform development of a novel drug candidate to treat ocular pain associated with dry eye syndrome.

Accepted ARVO abstract is listed below:

About Ocular Pain Associated with Dry Eye Syndrome

Dry eye syndrome is a clinical diagnosis that encompasses a broad range of distinct conditions with unique etiologies that share signs and symptoms, the most common of which are sensations of burning, stinging, itching or grittiness in the eyes. The objective of our program is to develop a topical ophthalmic analgesic to safely and effectively treat ocular discomfort associated with the diagnosis of dry eye. This product would also be useful for treating other types of ocular pain, such as post-surgical pain and pain associated with acute corneal injuries or abrasions.

Existing therapeutics for dry eye include topical cyclosporine (Restasis) and lifitegrast (Xiidra). Both drugs address the inflammatory component of the disease by inhibiting activation of T-cells, however signs and symptoms of dry eye frequently persist.

The objective of our program is to advance a topical ophthalmic analgesic that reduces ocular discomfort associated with dry eye by targeting a voltage-gated sodium channel in the cornea, NaV1.7, and reducing corneal pain. Our product has the potential to be broadly effective in the ~30 million Americans suffering from dry eye regardless of the etiology because it addresses the discomfort rather than the heterogeneous physiologic cause. The analgesic would complement therapeutics that reduce inflammation or improve tear film, allowing the patient to be comfortable over weeks to months required for these therapies take effect. It would also be a useful treatment for postoperative pain following certain surgical procedure and acute ocular injuries, such as corneal abrasion.
