OKYO Pharma Announces U.S. IND Filing on OK-101 for the Treatment of Dry Eye Disease

-OK-101 first-in-human Phase 2 trial will incorporate primary and secondary efficacy endpoints characterizing signs and symptoms of Dry Eye Disease-

London and Boston, MA, November 21, 2022 - 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, today announced that it filed an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) for the development of OK-101 to treat dry eye disease (DED).

Both nonclinical and clinical development plans on OK-101 were reviewed with the FDA in an earlier Pre-IND meeting facilitated by OKYO's contract research organization, Ora Inc, with the FDA agreeing to a first-in-human Phase 2 trial in DED patients. FDA also concurred with OKYO's plans for designating primary and secondary efficacy endpoints covering both a sign and a symptom of DED in the trial's clinical protocol.

"The filing of this IND with FDA is a key step for OKYO as we advance our plan to open a Phase 2 trial in DED patients in the first quarter of 2023," said Gary S. Jacob, Ph.D., CEO of OKYO Pharma. "We were pleased with the clear guidance we received from the FDA Pre-IND meeting earlier in the year. The fact that we are designating primary and secondary efficacy endpoints in this first-in-human trial is highly significant as should our upcoming trial of OK-101 meet its prespecified primary endpoint, it could accelerate the timeline to a new drug application (NDA) filing with the FDA."

"FDA's earlier feedback from the Pre-IND meeting confirmed our plans for the first-in-human study design to determine the safety and efficacy of OK-101 for the treatment of dry eye," said George Ousler, Senior Vice President for Ora. "Ora is looking forward to initiating the trial with OKYO and evaluating this innovative therapy to potentially help millions of patients suffering from this debilitating disease."  

"The successful filing of this IND on OK-101 has been a central and critical goal for the company this past year," said Raj Patil, Ph.D., CSO of OKYO Pharma. "We are excited to be moving this drug into clinical trials early next year and believe that OK-101 can provide a new way to treat DED patients who are presently not well-served by currently approved drugs."

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 has been shown to produce anti-inflammatory and neuropathic pain-reducing activities in mouse models of DED and corneal neuropathic pain, respectively, and is designed to combat washout through the inclusion of the lipid 'anchor' contained in the drug molecule to enhance the residence time of OK-101 within the ocular environment.

The person who arranged for the release of this announcement on behalf of the Company was Gary S. Jacob, Ph.D., Chief Executive Officer of OKYO.

About Dry Eye Disease

Dry eye disease is a multifactorial disease that results in ocular discomfort and tear film instability that can lead to ocular surface damage. It is often a chronic problem, particularly in older adults, and is expected to become even more prevalent with the aging population and increased use of digital screens such as computers and smart phones. Despite new product approvals, dry eye disease remains a significant unmet medical need and is one of the leading causes for patient visits to eye care specialists. Novel therapies that improve the signs and symptoms of dry eye disease will be beneficial to dry eye patients.
