Phentolamine Mesylate

DURHAM, N.C., Feb. 26, 2025 (GLOBE NEWSWIRE) -- Opus Genetics, Inc. (Nasdaq: IRD), a clinical-stage ophthalmic biotechnology company developing gene therapies for the treatment of inherited retinal diseases (IRDs) and other ophthalmic disorders, today announced completion of enrollment in the VEGA-3 Phase 3 clinical trial evaluating Phentolamine Ophthalmic Solution 0.75% for presbyopia. Opus also announced that enrollment in the LYNX-2 pivotal Phase 3 trial, evaluating Phentolamine Ophthalmic Solution 0.75% for the treatment of visual loss in low light conditions associated with keratorefractive surgery, is well-underway with anticipated completion of enrollment in the first half of 2025. In addition, the FDA has granted Fast Track designation for Phentolamine Ophthalmic Solution 0.75% as treatment of significant chronic night driving impairment with concomitant increased risk of motor vehicle accidents and debilitating loss of best spectacle corrected mesopic vision in keratorefractive patients with photic phenomena (i.e., glare, halos, starburst). Fast track status is designated to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. “We are pleased with the ongoing progress of both the VEGA-3 and LYNX-2 studies,” said Jay Pepose, M.D., PhD., Chief Medical Advisor at Opus Genetics. “Presbyopia affects millions of people and represents a daily challenge that can diminish independence and quality of life. Phentolamine Ophthalmic Solution 0.75% has the potential to transform how this condition is managed by offering a durable, non-invasive solution that improves near vision, without compromising nighttime distance vision. It also offers the potential to improve visual performance in patients who have undergone LASIK for vision correction, and who now have difficulty with low light vision and night-time vision disturbances. We look forward to sharing the results of these important studies and working with our partner to complete development in these two indications.” VEGA-3 Phase 3 Program in Presbyopia VEGA-3 is a randomized, double-masked, placebo-controlled, multi-center, Phase 3 clinical trial evaluating Phentolamine Ophthalmic Solution 0.75% in 545 participants with presbyopia. The primary endpoint is the percentage of participants with 15-letter improvement in photopic binocular distance-corrected near visual acuity (“DCNVA”) on the eighth day following their first visit. Participants are being followed a total of 48 weeks to collect chronic safety data. Recruitment has taken place at 39 investigational sites in the U.S. For more information on the VEGA-3 trial design and endpoints, please refer to www.ClinicalTrials.gov (NCT06542497). LYNX-2 Phase 3 Program in Dim Light Disturbances LYNX-2 is a randomized, double-masked, placebo-controlled Phase 3 clinical trial designed to evaluate Phentolamine Ophthalmic Solution 0.75% compared to placebo in subjects who underwent keratorefractive surgery and then reported decreased visual acuity under low light conditions. Target enrollment is 200 subjects, and the trial is more than 95% enrolled. The primary endpoint is a gain of 3 lines (or 15 letters) or more of distance vision improvement on a low contrast chart in low light conditions after 15 days of dosing. The LYNX-2 trial is being conducted under conditions of a Special Protocol Assessment (SPA) with the U.S. FDA. Additional information about LYNX-2 can be found at www.clinicaltrials.gov NCT06349759 . The U.S. FDA recently granted Fast Track designation for Phentolamine Ophthalmic Solution 0.75% as treatment of significant chronic night driving impairment in keratorefractive patients with reduced mesopic vision and photic phenomena. Fast Track designation is an important regulatory milestone with the potential to accelerate the development and review of new drugs intended to treat serious conditions with unmet medical needs. This designation offers Opus Genetics several key benefits, including more frequent interactions with the FDA, eligibility for Priority Review, as well as rolling review, allowing sections of the NDA to be submitted and evaluated on an ongoing basis. About Presbyopia Presbyopia is the most common age-related ocular condition. 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. Presbyopia reduces the eye's ability to focus on near objects due to the loss of lens elasticity and its ability to change shape. This progressive condition typically affects individuals over the age of 40 and can significantly impact quality of life and ability to perform everyday tasks such as reading, using digital devices, and other close-up activities. Presbyopia leads to the widespread use of reading glasses or bifocals. Phentolamine Ophthalmic Solution 0.75% is being developed to provide a non-invasive, convenient alternative to traditional corrective measures. About Decreased Vision in Low Light Conditions after Keratorefractive Surgery Decreased low contrast visual acuity under low light conditions occurs when the pupil dilates in low light conditions allowing peripheral unfocused rays of light to enter the eye, degrading image quality. It is not correctable with glasses and is often accompanied by glare, halos and starbursts at night. The condition is common in patients with increased peripheral ocular aberrations and ocular scatter from refractive surgery (including LASIK, PRK, SMILE, and RK). There are currently no FDA-approved treatments. Phentolamine Ophthalmic Solution 0.75% has a mechanism of action that moderately reduces pupil size, thereby blocking unfocused peripheral rays of light, without the increased risks of retinal tears or detachment associated with parasympathomimetic miotics that engage the ciliary muscle. It has the potential to be a treatment option that could improve patients’ ability to see, drive and function in low light. About Phentolamine Ophthalmic Solution 0.75% Phentolamine Ophthalmic Solution 0.75%, Opus Genetics’ late-stage product candidate, is a non-selective alpha-1 and alpha-2 adrenergic antagonist designed to reduce pupil size. 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 being developed for presbyopia and reduced mesopic low contrast and night vision disturbances after keratorefractive surgery. About Opus Genetics Opus Genetics is a clinical-stage ophthalmic biotechnology company developing gene therapies to treat patients with inherited retinal diseases (IRDs) and other treatments for ophthalmic disorders. The pipeline includes adeno-associated virus (AAV)-based gene therapies that address mutations in genes that cause different forms of bestrophinopathy, Leber congenital amaurosis (LCA) and retinitis pigmentosa. The company’s most advanced gene therapy program is designed to address mutations in the LCA5 gene, which encodes the lebercilin protein and is currently being evaluated in a Phase 1/2 open-label, dose-escalation trial, with encouraging early data. BEST1 gene therapy is designed to address mutations in the BEST1 gene, which is associated with retinal degeneration; A Phase 1/2 study will be initiated in 2025. The pipeline also includes Phentolamine Ophthalmic Solution 0.75%, a non-selective alpha-1 and alpha-2 adrenergic antagonist to reduce pupil size, and APX3330, a novel small-molecule inhibitor of Ref-1 to slow the progression of non-proliferative diabetic retinopathy. Phentolamine Ophthalmic Solution 0.75% is currently being evaluated in Phase 3 trials for treatment of presbyopia and reduced dim (mesopic) light low contrast vision following keratorefractive surgery.
