FAQ

Why Very Bullish?

The significant efficacy and safety data may lead to FDA approval and increased revenues. Historically, positive trial results have led to price surges in biotech stocks seeking FDA approval, such as in the case of several gene therapies by other companies.

How important is it?

The article provides critical insights into trial success and future FDA application, indicating high future revenue potential for IRD.

Why Long Term?

The potential FDA approval and subsequent commercialization of Phentolamine may take time, but demand for presbyopia solutions could lead to sustained higher stock prices as market adoption occurs.

Study met its primary and key secondary endpoints, demonstrating rapid and sustained improvement in near visual acuitySafety profile consistent with previous clinical trials and no treatment-related serious adverse events reported in the studyNo evidence of tachyphylaxis was observed in this study over the 6-week periodManagement to Host Webcast and Conference Call Today at 8:00 A.M. ET RESEARCH TRIANGLE PARK, N.C., June 26, 2025 (GLOBE NEWSWIRE) -- Opus Genetics, Inc. (Nasdaq: IRD), a clinical-stage biopharmaceutical company developing gene therapies for the treatment of inherited retinal diseases (IRDs) and small molecule therapies for other ophthalmic disorders, today announced positive topline results from VEGA-3, its second pivotal Phase 3 trial evaluating Phentolamine Ophthalmic Solution 0.75% for the treatment of presbyopia. Presbyopia is an ophthalmic disorder that involves the progressive loss of ability to focus on close objects that results in blurred near vision, difficulty seeing in dim light, and eye strain. The VEGA-3 trial met its primary endpoint, with a statistically significant 27.2% of participants treated with Phentolamine Ophthalmic Solution 0.75% achieving a ≥15-letter improvement in binocular distance-corrected near visual acuity (DCNVA), with less than a 5-letter loss in binocular best-corrected distance visual acuity (BCDVA) at 12 hours post-dose on Day 8, compared to 11.5% of patients on placebo (p<0.0001). The trial also met key secondary efficacy endpoints, reinforcing the benefit observed. “The results of the VEGA-3 trial reinforce our belief that Phentolamine Ophthalmic Solution 0.75% could offer an option to improve near vision for millions of adults affected by presbyopia,” said George Magrath, M.D., CEO, Opus Genetics. “The positive results from both our Phase 3 VEGA-2 and VEGA-3 trials support the submission of an application to the U.S. Food and Drug Administration (FDA), which we plan to file in the second half of 2025. I want to thank the participants and clinical teams who participated in VEGA-3 and who have helped us bring Phentolamine Ophthalmic Solution 0.75% to this point in development.” “These findings provide further validation of Phentolamine Ophthalmic Solution 0.75% as a differentiated approach to managing presbyopia, reflected by its ability to improve near vision while preserving distance vision without compromising low contrast vision,” said Jay Pepose, M.D., Ph.D., Chief Medical Advisor, Opus Genetics. VEGA-3 Phase 3 Study VEGA-3 is the second Phase 3 clinical trial evaluating the safety and efficacy of Phentolamine Ophthalmic Solution 0.75% in subjects with presbyopia. VEGA-3 is a multicenter, randomized, double-masked, placebo-controlled Phase 3 study that enrolled 545 participants across 40 sites in the United States. Subjects were randomized in a 3:2 ratio to receive either Phentolamine Ophthalmic Solution 0.75% or placebo, administered once daily in the evening. Top-Line Results: The primary endpoint was defined as the proportion of participants achieving a ≥15-letter Early Treatment Diabetic Retinopathy Study (ETDRS) (≥3-line) improvement in binocular DCNVA and with less than 5 letters of loss in binocular BCDVA from baseline at 12 hours post-dose on Day 8, as compared to placebo.27.2% of participants treated with Phentolamine Ophthalmic Solution 0.75% achieved a ≥15-letter improvement in DCNVA, with less than a 5-letter loss in BCDVA at 12 hours post-dose on Day 8, compared to 11.5% of patients on placebo (p<0.0001).20.6% of patients in the Phentolamine arm achieved ≥15-letter ETDRS (≥3-line) gain in DCNVA at 1-hour post-dose on Day 1 compared to 6.1% of those receiving placebo (p=0.0002).Significant patient-reported functional benefit at Days 3 and 8 and Week 6 were observed with patients reporting satisfaction with near vision upon awakening (p<0.0001) and improvement in their near vision (p<0.0001).There was no evidence of tachyphylaxis observed after 6 weeks compared to the primary endpoint at Day 8 12 hours post-dose.Phentolamine Ophthalmic Solution 0.75% demonstrated a safety profile consistent with previous trials, with no new safety signal identified and no treatment-related serious adverse events reported in this study. The most common (≥5%) treatment-emergent adverse events included conjunctival hyperemia, instillation site irritation, and dysgeusia and all of which were predominantly mild. A low rate of headache (2.6%) was reported over the study period. VEGA-3 patients will continue to be monitored for long-term safety over 48 weeks. Additional information on the VEGA-3 study design is available on ClinicalTrials.gov (NCT06542497). Opus Genetics and Viatris (through its affiliate) are parties to a global licensing agreement which provides for the development of Phentolamine Ophthalmic Solution 0.75% and grants exclusive rights to Viatris to commercialize Phentolamine Ophthalmic Solution 0.75% in the United States. Conference Call & Webcast Details Opus Genetics management will host a webcast and conference call today at 8:00 a.m. Eastern Time to discuss the VEGA-3 results and provide a corporate update.

About Phentolamine Ophthalmic Solution 0.75% Phentolamine Ophthalmic Solution 0.75% is a non-selective alpha-1 and alpha-2 adrenergic antagonist to reduce pupil size, administered as an eye drop. It works by uniquely blocking the alpha-1 receptors found on the radial iris dilator muscles, which are activated by the alpha-1 adrenergic receptors, without affecting the ciliary muscle. Phentolamine Ophthalmic Solution 0.75% is currently being evaluated in two Phase 3 programs for the treatment of presbyopia and dim (mesopic) light vision disturbances after keratorefractive surgery (LYNX clinical program) and presbyopia (VEGA clinical program). About Presbyopia Presbyopia is the progressive loss of ability to focus on near objects that typically becomes noticeable in the early to mid-40s. As the eye ages, the ability to focus for reading and other tasks that require clear vision at near distances decreases. Presbyopia patients experience blurred near vision, difficulty seeing in dim light and eye strain. This ubiquitous condition leads to the widespread use of reading glasses or bifocals. It is estimated that 128 million Americans, and over 2 billion people worldwide, have presbyopia, and this number is expected to grow as the population ages. About Opus Genetics Opus Genetics is a clinical-stage biopharmaceutical company developing gene and small molecule therapies for vision-threatening eye diseases.
