Jay Pepose, MD, PhD, Founder and Medical Director of the Pepose Vision Institute and Professor of Clinical Ophthalmology at Washington University School of Medicine, has nearly 40 years of experience as both a treating physician and a widely published researcher. He is the founder and Medical Director of the Pepose Vision Institute and a professor of Clinical Ophthalmology & Visual Sciences at Washington University School of Medicine in St. Louis. Dr. Pepose is actively involved in clinical trials and has served as an investigator on over 30 studies evaluating new therapeutics and technology in a broad range of ophthalmic indications, including dry eye. He has published over 200 peer-reviewed articles and has served on the editorial boards of several prestigious ophthalmology journals. Dr. Pepose received an A.B. and M.A. in neurophysiology from Brandeis University and completed the M.D. Ph.D. program at the UCLA School of Medicine. Dr. Pepose completed his ophthalmology residency at the Wilmer Institute at the Johns Hopkins Medical Center and his fellowship training at Georgetown University Medical Center.

Anat Galor, MD, MSPH, Professor of Ophthalmology, University of Miami Miller School of Medicine, is a cornea and uveitis trained specialist with dual appointments at the Bascom Palmer Eye Institute and the Miami VA medical center. Dr. Galor completed an ophthalmology residency at the Cole Eye Cleveland Clinic, a uveitis fellowship at the Wilmer Eye Institute, and a cornea and external diseases fellowship at Bascom Palmer Eye Institute. Dr. Galor currently runs the ocular surface pain program at the Bascom Palmer Eye Institute and the Miami VA and has focused her research on understanding mechanisms of pain in dry eye, with an emphasis on studying new diagnostic and treatment modalities.

In a previous preliminary data readout, OK-101 showed statistically significant drug effects in FDA-recognized efficacy endpoints as early as the 15-day first visit after dosing. Additionally, statistically significant improvements were observed in both a "sign" (total conjunctival staining) and two "symptoms" (burning/stinging and blurred vision), which are FDA-recognized endpoints of dry eye disease.

OK-101 Phase 2 Trial in DED Patients

The double-masked, randomized, placebo-controlled Phase 2 trial was conducted at six sites in the U.S. and enrolled 240 subjects with DED dosed twice-daily (BID). Patients were randomly divided into 3 cohorts, with one of the cohorts dosed with 0.05% OK-101 (n=81), a second with 0.1% OK-101 (n=80), and the third cohort with vehicle (n=79). The duration of a patient's treatment was 14 weeks, including a 2-week run-in period on placebo, to exclude placebo responders from the study, followed by 12 weeks in the randomized portion of the study.

About OK-101

OK-101 is a lipid conjugated chemerin peptide agonist of the ChemR23 G-protein coupled receptor which is typically found on immune cells of the eye responsible for the inflammatory response. OK-101 was developed using a membrane-anchored-peptide technology to produce a novel long-acting drug candidate for treating dry eye disease. OK-101 has been shown to produce anti-inflammatory and pain-reducing efficacy signals in mouse models of dry eye disease and corneal neuropathic pain (NCP), respectively, and is designed to combat washout through the inclusion of the lipid anchor built into the drug molecule to enhance the residence time of OK-101 within the ocular environment. OK-101 recently showed statistical significance in multiple endpoints in a recently completed Phase 2, multi-center, double-blind, placebo-controlled trial of OK-101 to treat DED.
