London, December 13, 2021 – OKYO Pharma Limited (LSE: OKYO; OTCQB: EMMLF), a biotechnology company focused on the discovery and development of novel molecules to treat inflammatory dry eye diseases (DED) and ocular pain, is pleased to announce that its drug candidate OK-101 which was developed to treat DED through its anti-inflammatory mode of action also shows potent ocular pain reducing property determined using a mouse model of corneal neuropathic pain, establishing the potential to treat both pain and inflammation, the most common symptoms of dry eye, with a single drug.
In collaboration with Pedram Hamrah, MD, Interim Chair of Ophthalmology, cornea specialist, and clinician-scientist at Tufts Medical Center, Boston, OK-101 was demonstrated to suppress corneal pain in a ciliary nerve ligation mouse model of neuropathic corneal pain developed in Dr. Hamrah’s laboratory. OK-101 was topically administered to mice in comparison to the positive control gabapentin which was administered via intraperitoneal injection. Pain relief was evaluated by an eye-wipe count, and OK-101 was shown to reduce corneal pain similar to that of gabapentin, a commonly used oral drug for neuropathic pain. Notably, the drug concentration of OK-101 used in this study was identical to that used in mouse models of DED that demonstrated ocular anti-inflammatory activity.
“Ocular pain, which can exhibit as a severe, chronic or debilitating condition in patients suffering from a host of ophthalmic conditions, is presently treated by various topical and systemic treatments in an off label fashion,” said Dr. Hamrah. “However, there are no approved commercial treatments currently available for this condition, and we are excited about these positive results with OK-101 in our neuropathic corneal pain model of this disease.”
“The pain relieving potential of a dry eye drug is very important because a considerable number of dry eye patients with chronic inflammation suffer from ocular pain, and a burning and gritty sensation,” said Raj Patil, PhD, Chief Scientific Officer of OKYO. “The discovery of the pain reducing feature of OK-101, in addition to its known anti-inflammatory activity, offers the opportunity that our drug could potentially provide pain relief in addition to reducing ocular inflammation in the millions of patients suffering from DED.”
“We are currently focused on finishing the pre-IND work on OK-101 and are planning to file the IND on OK-101 to treat DED in Q3 2022, followed by the commencement of a Phase 2 trial in DED patients in Q4 2022,” said Dr. Gary S. Jacob, CEO of OKYO. “The recent discovery that OK-101 has both anti-inflammatory and ocular pain suppressing activity is an exciting development, and we believe that OK-101 can provide a new way to treat DED patients who are presently not well served by drugs currently approved for treating dry eye disease.”
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.

Notes for Editors:
OK-101 is a novel long-acting G protein-coupled receptor-based lipidated chemerin peptide developed to bind to ChemR23 receptors typically found on immunological cells present in the eye. ChemR23 plays an important role in the inflammatory response, and binding of OK-101 to ChemR23 has been shown to produce anti-inflammatory activity in mouse models of DED. OK-101 was developed using a membrane-anchored-peptide (MAP) technology to produce a long-acting drug candidate designed to combat washout through the inclusion of a lipid ‘anchor’ within its molecular structure to enhance residence time on the ocular surface.

About Dry Eye Disease (DED)
Dry eye 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, DED 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.
