FDA clears compassionate urcosimod use as OKYO (OKYO) plans Phase 2b/3 NCP trial
Rhea-AI Filing Summary
OKYO Pharma Limited reports that the U.S. Food and Drug Administration has authorized a single-patient expanded access (compassionate use) IND for its drug candidate urcosimod (0.05%) to treat a patient with severe neuropathic corneal pain who has limited options and no FDA-approved treatments available. The IND was submitted by Pedram Hamrah, MD, at the University of South Florida, and urcosimod is being provided by OKYO under this authorization.
The company notes that urcosimod previously received the first IND to treat neuropathic corneal pain and was granted FDA fast track designation. OKYO recently reported positive pain-reduction data in an 18-patient Phase 2 trial in neuropathic corneal pain and earlier statistically significant results in a 240-patient Phase 2 trial in dry eye disease. It plans to start a 120-patient Phase 2b/3 multiple-dose study of urcosimod for neuropathic corneal pain this year.

FAQ
What did the FDA authorize for OKYO (OKYO) in this 6-K?
The FDA authorized a single-patient expanded access (compassionate use) IND for urcosimod (0.05%) in a patient with severe neuropathic corneal pain. The IND was submitted by Pedram Hamrah, MD, at the University of South Florida, and urcosimod is being supplied by OKYO Pharma.
What is urcosimod and what conditions is OKYO (OKYO) targeting?
Urcosimod (formerly OK-101) is a lipid conjugated chemerin peptide agonist of the ChemR23 G-protein coupled receptor found on immune cells of the eye and on certain neurons and glial cells. OKYO is developing it as an investigational therapy for neuropathic corneal pain (NCP) and for inflammatory eye diseases, including dry eye disease.
What prior clinical results has OKYO (OKYO) reported for urcosimod?
OKYO reports that urcosimod produced anti-inflammatory and pain-reducing activity in preclinical models and showed positive pain-reduction data in an 18-patient randomized, placebo-controlled, double-masked Phase 2 trial in neuropathic corneal pain. It also showed clear statistical significance in multiple endpoints in an earlier 240-patient Phase 2 trial in dry eye disease.
What are OKYO Pharma’s next clinical plans for urcosimod in NCP?
OKYO states that it plans to initiate a 120-patient Phase 2b/3 multiple-dose study of urcosimod to treat neuropathic corneal pain this year, building on its previously completed Phase 2 trial in NCP.
What is neuropathic corneal pain (NCP) and why is it important for OKYO (OKYO)?
Neuropathic corneal pain is described as a chronic, often debilitating condition marked by severe eye pain and sensitivity, sometimes affecting the face or head. It is thought to involve corneal nerve damage or dysfunction and inflammation. The company notes that there are no FDA-approved therapies specifically for NCP, so patients are often treated off-label with limited success, highlighting the potential need addressed by urcosimod.
What regulatory designations has urcosimod received from the FDA?
OKYO states that urcosimod was granted the first IND to treat patients with neuropathic corneal pain and has been awarded fast track designation by the FDA. The newly reported authorization adds a single-patient expanded access (compassionate use) IND for a severe NCP case.
