First patient dosed in the pediatric cohort of the Phase 1/2 trial of OPGx-LCA5; initial data on the cohort anticipated by Q3 2025

New 12-month data on the first three adult OPGx-LCA5 patients to be presented at a major medical conference in Q2 2025

FDA meeting scheduled in March 2025 to discuss Phase 3 trial design and registrational endpoints for OPGx-LCA5

DURHAM, N.C., Feb. 18, 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 therapies to treat other ophthalmic disorders, today announced that the first pediatric patient was dosed in its ongoing Phase 1/2 clinical trial evaluating OPGx-LCA5, its investigational gene therapy for the treatment of Leber congenital amaurosis (LCA). Opus plans to share initial data from the pediatric cohort by Q3 2025.

The ongoing trial has achieved early clinical proof of concept, demonstrating meaningful visual improvement starting as early as one month following treatment in the first three adult patients, as was evident in the 6-month data first released in October 2024 and reviewed at a company-sponsored KOL event in December 2024 (HERE). Opus now plans to share the new 12-month data on these three adult LCA5 patients at a major medical conference during the second quarter of 2025. An FDA Type D meeting is scheduled in March to discuss the pivotal trial design and endpoints.

"We are proud of the progress of our ongoing OPGx-LCA5 clinical trial and pleased to reach this critical next step as we expand the trial to pediatric patients. Early intervention in pediatric LCA5 patients is particularly important, as it offers the best chance to preserve or restore visual function before the disease progresses," said George Magrath, M.D., Chief Executive Officer of Opus Genetics. "We are encouraged by the new 12-month results that confirm the durability of the positive response observed at 6 months. This data will be shared in our scheduled meeting with the FDA in March to discuss a proposed Phase 3 trial design and registrational endpoints for the OPGx-LCA5 program. We are hopeful that this may offer a potentially life-changing therapeutic option for individuals living with LCA and will continue to work closely with the medical and patient communities to advance this important program. We're grateful to our partners at the University of Pennsylvania for their hard work and dedication to our program."

Phase 1/2 Trial Design

This clinical trial was designed to evaluate the safety and preliminary efficacy of subretinal gene therapy with OPGx-LCA5 in patients with inherited retinal degeneration due to biallelic mutations in the LCA5 gene. It is an open-label, Phase 1/2 trial evaluating OPGx-LCA5. Efficacy endpoints include measurement of functional vision using: 1) the Multi-Luminance orientation and Mobility Test (MLoMT); 2) Full-Field Stimulus Testing (FST), which measures the retina's sensitivity to light; and 3) microperimetry, which measures point-wise sensitivity to light. For more information, visit clinicaltrials.gov (NCT05616793).

The six-month results on adult patients treated with OPGx-LCA5 were presented in a Key Opinion Leader (KOL) webinar, hosted by Opus on December 11, 2024. A replay of the webinar can be accessed here.

About OPGx-LCA5

OPGx-LCA5 is designed to address a form of Leber congenital amaurosis (LCA) due to biallelic mutations in the LCA5 gene (LCA5), which encodes the lebercilin protein. LCA5-associated inherited retinal disease is an early-onset severe inherited retinal dystrophy. Studies in patients with this mutation have reported evidence for the dissociation of retinal architecture and visual function in this disease, suggesting an opportunity for therapeutic intervention through gene augmentation. OPGx-LCA5 uses an adeno-associated virus 8 (AAV8) vector to precisely deliver a functional LCA5 gene to the outer retina. OPGx-LCA5 is currently being evaluated in a Phase 1/2 clinical trial at the University of Pennsylvania designed to evaluate its safety and preliminary efficacy in patients with inherited retinal degeneration due to biallelic mutations in the LCA5 gene.

About Opus Genetics

Opus Genetics is a clinical-stage ophthalmic biotechnology company developing gene therapies to treat patients with IRDs and other treatments for ophthalmic disorders. The pipeline includes adeno-associated virus (AAV)-based investigational gene therapies that address mutations in genes that cause different forms of bestrophinopathy, Leber congenital amaurosis (LCA) and retinitis pigmentosa. Our most advanced investigational 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 trial, with encouraging early data. BEST1 investigational gene therapy is designed to address mutations in the BEST1 gene, which is associated with retinal degeneration; we expect that a Phase 1/2 trial to be initiated in 2025. The pipeline also includes Phentolamine Ophthalmic Solution 0.75%, a non-selective alpha-1 and alpha-2 adrenergic antagonist being investigated to reduce pupil size, and APX3330, a novel small-molecule inhibitor of Ref-1 being investigated to slow the progression of non-proliferative diabetic retinopathy (DR). Phentolamine Ophthalmic Solution 0.75% is currently being evaluated in Phase 3 trials for treatment of presbyopia and reduced dim (mesopic) light vision following keratorefractive surgery. We have reached agreement with the FDA on a SPA for a Phase 3 trial to evaluate oral APX3330 for the treatment of DR. For more information, please visit www.opusgtx.com.
