OKYO Pharma Begins Phase 3 Trial Of Urcosimod For Neuropathic Corneal Pain
OKYO Pharma (OKYO) has started its Phase 3 NEPTUNE trial for urcosimod, a potential treatment for neuropathic corneal pain (NCP). The trial, enrolling patients in the U.S. and Europe, will evaluate the drug's efficacy over 12 weeks. Urcosimod targets the ChemR23 receptor and has shown promise in earlier studies. NCP lacks FDA-approved treatments, representing an unmet medical need. OKYO shares closed at $1.47 on Monday.
