OKYO Pharma Announces First-Patient First-Visit for Phase 2 Trial evaluating Efficacy and Safety of OK-101 in Patients with Dry Eye Disease

· Trial designed with pre-specified primary efficacy endpoints

· Top-line data from trial anticipated before end of 2023

London and New York, NY, May 2, 2023 – OKYO Pharma Limited (LSE: OKYO; NASDAQ: OKYO), an ophthalmology-focused bio-pharmaceutical company which is developing OK-101 to treat dry eye disease to address the significant unmet need in this multi-billion-dollar market, is pleased to announce that the first patient has been screened for its phase 2, multi-center, randomized, double–blinded, placebo-controlled trial, evaluating the efficacy and safety of OK-101 ophthalmic solution in subjects with dry eye disease (DED).

“The initiation of this trial of topically applied OK-101 to treat dry eye disease marks a significant step for the company as we have been laser focused on moving this drug candidate into clinical trials over the last 18 months,” said Gary S. Jacob, Ph.D., CEO of OKYO Pharma. “Importantly, this first clinical study is designed to include pre-specified primary efficacy endpoints which are the hallmark of phase 3 registration trials, and the results from this trial are anticipated before the end of this year. The drug has been shown in pre-clinical studies to have potent anti-inflammatory and neuropathic corneal pain activities, and we are eager to evaluate its potential benefits in the clinic.”

Dry eye disease is a common condition that occurs when an individual’s tears are unable to adequately lubricate the eyes. This condition affects approximately 49 million people in the U.S. alone and has been a difficult one to positively diagnose and to treat due to the multifactorial nature of the condition. A number of contributing factors can lead to this condition, including age, sex, certain medical conditions, reduced tear production and tear film dysfunction. Tear film instability typically leads to inflammation and damage to the ocular surface.

About the Phase 2 Trial Design

This phase 2, multi-center, randomized, double–blinded, placebo-controlled study is planned to enroll approximately 240 subjects with DED who will be randomly divided into 3 cohorts of 80 patients. Participants will be selected based on specific inclusion and exclusion criteria. The three cohorts will be comprised of one cohort treated with placebo, a second cohort treated with a low dose of OK-101, and the third cohort receiving a higher dose of OK-101. The drug and placebo will be administered in both eyes twice daily for 12 weeks. The duration of a patient’s treatment will be approximately 14 weeks, including a 2-week run-in period and 12 weeks of treatment. The protocol for the study includes two prespecified primary endpoints and a number of secondary endpoints. Further details regarding the specifics of the trial are posted on the ClinicalTrials.gov public website (ClinicalTrials.gov Identifier: NCT05759208).

About OK-101

OK-101 is a lipid conjugated chemerin peptide antagonist 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 (MAP) 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 activities in mouse models of dry eye disease and corneal neuropathic pain; and is designed to combat washout through the inclusion of the lipid ‘anchor’ contained in the candidate drug molecule to enhance the residence time of OK-101 within the ocular environment.
