RESEARCH TRIANGLE PARK, N.C., May 12, 2026 (GLOBE NEWSWIRE) -- Opus Genetics, Inc. (NASDAQ:IRD) (the "Company" or "Opus Genetics"), a clinical-stage biopharmaceutical company developing gene therapies to restore vision and prevent blindness in patients with inherited retinal diseases (IRDs), today announced financial results for the first quarter ended March 31, 2026, and provided a corporate update.

"With encouraging momentum across both our LCA5 and BEST1 gene therapy programs, Opus Genetics is entering a defining stretch where we believe our precision targeted approach can reshape what's possible for patients with inherited retinal diseases," said George Magrath, M.D., Chief Executive Officer of Opus Genetics. "Our upcoming BEST1 Cohort 1 clinical data and June R&D Science Forum will provide key opportunities to showcase the depth and maturity of our science and pipeline. Backed by a strong balance sheet and disciplined capital strategy, we are well-positioned to advance our lead programs toward pivotal trials, and accelerate our earlier‑stage RDH12, MERTK, and RHO programs into the clinic."

Pipeline Updates

Research & Development (R&D) Science Forum

Opus Genetics plans to host an R&D Science Forum on Tuesday, June 16, 2026, from 10:00 am – 12:00 pm ET, with management and key opinion leaders (KOLs) highlighting earlier-stage gene therapy programs entering clinical testing and IRD global market opportunities. Registration for the event will be available on the Events page of the Opus Genetics website.

OPGx-BEST1

Enrollment completed in Cohort 1 of the Phase 1/2 trial (BIRD-1) including participants with both dominant and recessive forms of BEST disease, with the final participant scheduled for dosing this month.
Baseline demographics were presented at the Association for Research in Vision and Ophthalmology (ARVO) 2026 Annual Meeting with the related poster presentation available on the Publications & Presentations page of the Opus Genetics website. Additionally, a slide presentation and video summary recording titled "OPGx-BEST1 Cohort 1 Baseline Demographics and Key Endpoints for IRDs" are provided on the IR Presentations page of the Opus Genetics website.
Opus Genetics expects to announce three-month topline data from Cohort 1 of the Phase 1/2 trial in September 2026.

OPGx-LCA5

Positive six-month pediatric cohort data was presented at ARVO 2026; robust and consistent improvements were observed in cone-mediated function with average gains of approximately 1.5 log unit in cone sensitivity, reaching normal ranges after a single dose. Improvements were also observed in objective measures, visual acuity, and functional vision. The therapy was well tolerated, with most adverse events anticipated, mild, and not related to OPGx-LCA5.
The U.S. Food and Drug Administration (FDA) granted acceptance of the LCA5 program into the Rare Disease Evidence Principles (RDEP) program, which is designed to provide guidance on the types of evidence that can be used to demonstrate substantial evidence of effectiveness, including the potential use of a single adequate and well-controlled study supported by confirmatory evidence.
Recruitment is ongoing in the run-in period for the pivotal Phase 3 trial. In parallel, the clinical and commercial batch of drug product is being manufactured. Dosing with OPGx-LCA5 is expected to start in the fourth quarter of 2026.

OPGx-RDH12

OPGx-RDH12 is being developed to deliver a functional RDH12 gene to photoreceptors using an AAV vector.
This program is expected to enter the clinic in the fourth quarter of 2026. Funding is supported by the RDH12 Alliance.

OPGx-MERTK

OPGx-MERTK is being developed for retinal degeneration caused by mutations in the MERTK gene, which plays a critical role in phagocytosis of photoreceptor outer segments by RPE cells.
Clinical development activities are underway. Funding is supported by a consortium led by Abu Dhabi's Healthcare Research and Innovation Fund.

OPGx-RHO

Preclinical data presented at ARVO 2026 and the Foundation Fighting Blindness Retinal Therapeutics Innovation Summit 2026 provided safety and efficacy data on the use of OPGx-RHO in two large animal models of autosomal-dominant retinitis pigmentosa (adRP). This preclinical work was co-funded by the Foundation Fighting Blindness and the National Institutes of Health.
This program is expected to enter the clinic in 2027.

Financial Results for the First Quarter Ended March 31, 2026

Cash Position: As of March 31, 2026, Opus Genetics had cash and cash equivalents of $60 million. Subsequent to the end of the period, the Company entered into a strategic financing agreement with Oberland Capital Management, which included funding of a principal amount of $35 million of senior secured notes and a commitment to a $5 million equity investment, which is expected to close on or about May 22, 2026, subject to the satisfaction of customary closing conditions. With approximately $90 million in current cash, and potential future fundings under the facility with Oberland Capital Management, the Company believes its aggregate cash resources will fund operations into 2029. This estimate excludes any potential proceeds from callable warrants or future milestone payments.

Revenue: License and collaborations revenue totaled $2.2 million for the quarter ended March 31, 2026, compared to $4.4 million for the same period in 2025. Revenue in both periods came primarily from reimbursement of research and development (R&D) services based on the Company's collaboration with Viatris, Inc.

Research and Development (R&D) Expenses: R&D expenses were $10.6 million for the quarter ended March 31, 2026, compared to $8.0 million for the same period in 2025. The increase was primarily attributable to higher manufacturing costs associated with the Company's IRD programs, partially offset by lower clinical costs associated with the Company's phentolamine-related programs. R&D expenses included $0.4 million and $0.3 million in stock-based compensation expense for the three months ended March 31, 2026 and 2025, respectively.

General and Administrative (G&A) Expenses: G&A expenses were $5.9 million for the quarter ended March 31, 2026, compared to $6.3 million for the same period in 2025. The decrease was primarily attributable to lower legal costs, partially offset by higher employee compensation-related costs. G&A expenses included $1.1 million and $0.6 million in stock-based compensation expense for the three months ended March 31, 2026 and 2025, respectively.

Net Loss: Net loss for the quarter ended March 31, 2026 was $65.5 million, or ($0.75) per basic and diluted share, compared to a net loss of $8.2 million, or ($0.24) per basic and diluted share, for the same period in 2025. The increase in net loss was primarily due to a non-cash expense, driven by the increase in the fair value change in warrant liabilities associated with the Company's March 2025 warrants, and higher R&D expenses as discussed above.
