A Phase 1/2 Dose Escalation Followed by a Masked, Randomized, Placebo-Controlled Study to Evaluate Topical Insulin for Neuroprotection in Open Angle Glaucoma
Stanford University
Summary
This study evaluates the safety and preliminary efficacy of topical sterile human insulin eye drops (EYED-002) in patients with open-angle glaucoma. The study uses a phase 1/2 dose-escalation design followed by a masked, randomized, placebo-controlled phase. Insulin is formulated as preservative-free eye drops and delivered once daily. The primary objective is to determine the safety profile of topical insulin; secondary objectives assess effects on retinal structure, visual field, visual acuity, contrast sensitivity, and quality of life.
