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].

Company Overview - Opus Genetics, Inc. is a clinical-stage biopharmaceutical company focused on developing gene therapies for inherited retinal diseases (IRDs) and small molecule therapies for other ophthalmic disorders [3] - The company's pipeline includes AAV-based gene therapies targeting conditions such as Leber congenital amaurosis (LCA), bestrophinopathy, and retinitis pigmentosa [3] - Lead gene therapy candidates include OPGx-LCA5, currently in a Phase 1/2 trial for LCA5-related mutations, and OPGx-BEST1 for BEST1-related retinal degeneration [3] - Additionally, the company is advancing Phentolamine Ophthalmic Solution 0.75%, which is approved for one indication and is being studied in two Phase 3 programs for presbyopia and low light vision disturbances [3] Upcoming Presentations - Opus Genetics will present its IRD gene therapy programs at several scientific conferences in September 2025 [1] - Presentation at the Ophthalmology Futures Forum will focus on "Gene & Cell Therapies for Rare & Common Retinal Diseases: Hype Vs Progress" on September 3, 2025 [2] - At the RD 2025 International Symposium, the company will share one-year results from a Phase I/II study of OPGx-LCA5 for inherited retinal degeneration due to biallelic mutations in the LCA5 gene [2] - The LSX World Congress will feature a presentation titled "The Equation for Maturation: Biotech Requirements to Achieve Scale" [2] Key Personnel - Sally Tucker, Ph.D., Senior Vice President Clinical Development, will present at the Ophthalmology Futures Forum and participate in a panel discussion in Paris, France on September 3, 2025 [4] - Ash Jayagopal, Ph.D., Chief Scientific & Development Officer, will present in Prague, Czech Republic on September 15, 2025 [4] - Ben Yerxa, Ph.D., President, will also participate in a panel discussion in Boston, MA on September 17, 2025 [4]

Core Insights - Opus Genetics, Inc. is presenting results from the LYNX-1 Phase 3 study of Phentolamine Ophthalmic Solution 0.75% at the World Cornea Congress IX, focusing on its potential to treat dim light disturbances in patients, particularly those who have undergone keratorefractive surgery [1][3][4] Study Results - The LYNX-1 Phase 3 study met its primary endpoint, showing that 13% of participants treated with Phentolamine gained 15 or more letters of mesopic low contrast distance visual acuity (mLCVA) at Day 8 compared to 3% in the placebo group (p<0.05) [5] - At Day 15, 21% of Phentolamine-treated participants gained 15 or more letters of mLCVA compared to 3% in the placebo group (p<0.01) [5] - Patient-reported outcomes for glare, halos, and starbursts were significantly lower in the Phentolamine group at Day 15 (p<0.01) [5] - In a subset analysis of post-LASIK participants, 29% of those treated with Phentolamine gained 15 or more letters of mLCVA at Day 8 compared to 9% in the placebo group [5] - The positive results from the LYNX-1 study support the ongoing Phase 3 LYNX-2 trial, with topline results expected in mid-2025 [5] Company Overview - Opus Genetics is a clinical-stage ophthalmic biotechnology company focused on developing gene therapies for inherited retinal diseases and other ophthalmic disorders [4] - The company's pipeline includes AAV-based investigational gene therapies targeting mutations in genes associated with various retinal diseases, with the most advanced program addressing mutations in the LCA5 gene [4] - Phentolamine Ophthalmic Solution 0.75% is being investigated for its ability to reduce pupil size and improve vision in patients with reduced mesopic vision following keratorefractive surgery [6]
