• Encouraging 68% improvement in responder rate results from patients who achieved both the conjunctival staining “sign” and ocular pain “symptom” endpoints from the 240 patient Phase 2 Dry Eye Disease (DED) trial
  
  
• Conjunctival staining and ocular pain represent potential co-primary endpoints to be explored in future trials
  

LONDON and NEW YORK, July 10, 2024 (GLOBE NEWSWIRE) -- OKYO Pharma Limited (NASDAQ: OKYO), a clinical-stage biopharmaceutical company developing innovative ocular therapies for the treatment of inflammatory dry eye disease (DED), a multi-billion-dollar market, and neuropathic corneal pain (NCP), an ocular condition associated with pain but without an FDA approved therapy, today announced promising new categorical data analyses from the recent OK-101 Phase 2 trial in DED patients. These analyses have identified conjunctival staining and ocular pain as the highest potential “sign” and “symptom” co-primary endpoints to be explored in the next DED trial of OK-101.

“The data from this first in-human trial of OK-101 in patients with DED have established a clear road map for future clinical development in this indication,” said Gary S. Jacob, Ph.D., CEO of OKYO Pharma. “Through our analytical work we have concluded that conjunctival staining and ocular pain represent important and de-risked endpoints to be studied further to help underserved patients whose dry eye symptoms include pain component. Furthermore, this trial demonstrated a favorable tolerability profile for OK-101, with an excellent eyedrop comfort score for a topically administered drug.”

“Dry eye disease encompasses a diverse and dissatisfied patient population who needs treatment alternatives to available anti-inflammatory medicines which are insufficient to alleviate the broad spectrum of bothersome ocular symptoms encompassed by this condition,” said Gabriele Cerrone, Non-Executive Chairman of OKYO Pharma. "We continue to advance our innovative program which focuses on the segment of patients most impacted by ocular pain, and will evaluate next steps for dry eye with our advisors and the regulatory agencies.”

Categorical Analysis Details:

Recently released data from the Phase 2, randomized, double-masked, placebo-controlled trial evaluating the safety and efficacy of OK-101 ophthalmic solution in subjects with DED were analyzed by categorical evaluation of the data set and responder-rate analyses. Importantly, the data set for the analysis utilized the full Intent-to-Treat population of 240 patients (for additional details, please refer to slides in the recently issued 6-K filing).  

Key findings are highlighted in Figure 1 below which evaluated responder rates for those patients demonstrating at least 12.5% reduction in conjunctival sum staining combined with at least a 30% reduction in the observed symptom (i.e., ocular pain, blurred vision, burning/stinging) as measured by improvement from baseline through the last study visit at Day 85.

• Notably, the number of patients showing both a reduction in conjunctival sum staining and in the pain symptom in the OK-101-treated group was 34.2% compared to 20.3% in the placebo-treated group, a 68% improvement.
• Similarly, the number of patients with reduction in conjunctival sum staining and burning/stinging symptoms were also numerically higher in the OK-101-treated group (32.9%) compared to the placebo-treated group (20.3%), with a 62% improvement.
• There was a smaller 19% difference in the responder rates for patients reporting both a combination of conjunctival staining and blurred vision.

About Dry Eye Disease

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 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.
