Opus Genetics Doses First Patient in Pivotal LYNX-3 Phase 3 Trial Evaluating Phentolamine Ophthalmic Solution 0.75% in Keratorefractive Patients With Visual Disturbances Under Mesopic, Low-Contrast Conditions

Core Viewpoint - Opus Genetics has initiated the first patient dosing in LYNX-3, a pivotal Phase 3 clinical trial for Phentolamine Ophthalmic Solution 0.75%, aimed at treating chronic night driving impairment in keratorefractive patients with reduced mesopic vision [1][2]. Group 1: Clinical Trial Details - LYNX-3 is the second Phase 3 trial for this indication, designated as Fast Track by the FDA, and follows a Special Protocol Assessment [2]. - The trial will enroll approximately 200 adults with decreased visual acuity in low-light conditions post-keratorefractive surgery, including LASIK and PRK [5]. - Participants will be randomized to receive either Phentolamine Ophthalmic Solution 0.75% or placebo for about two weeks [5]. Group 2: Treatment Mechanism and Benefits - Phentolamine Ophthalmic Solution 0.75% is a non-selective α1/α2 adrenergic antagonist designed to reduce pupil size in low-light conditions, potentially improving visual quality by decreasing the impact of peripheral light rays [3][7]. - The primary endpoint of the trial is the percentage of participants achieving a ≥15-letter improvement in mesopic low-contrast visual acuity at Day 15 [6]. - Key secondary endpoints include patient-reported outcomes related to night driving and visual disturbances such as glare and halos [6]. Group 3: Company Overview - Opus Genetics is a clinical-stage biopharmaceutical company focused on gene therapies for inherited retinal diseases and small-molecule therapies for ophthalmic disorders [9]. - The company is advancing Phentolamine Ophthalmic Solution 0.75% in two Phase 3 programs, with one approved indication for drug-induced mydriasis and positive data for presbyopia [4][9].
