About Urcosimod (formerly called OK-101)

Urcosimod 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, as well as on neurons and glial cells in the dorsal root ganglion. Urcosimod has been shown to produce anti-inflammatory and pain-reducing activities in a mouse model of dry eye disease and in a neuropathic corneal pain mouse model, respectively. OKYO recently announced positive data on NCP pain reduction in a randomized, placebo-controlled, double-masked Phase 2a trial involving 18 neuropathic corneal pain subjects. Urcosimod has shown significant pain reduction in an earlier 240 subject Phase 2, multi-center, double-masked, placebo-controlled trial in DED, which supports the development rationale in NCP.
