RESEARCH TRIANGLE PARK, N.C., Aug. 06, 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 second quarter ended June 30, 2026, and provided a corporate update.

“With a focus on execution, we are rapidly advancing five gene therapy programs that address significant unmet need in inherited retinal diseases, with OPGx-BEST1 Cohort 1 clinical data targeted for the second week of September and four additional clinical readouts expected in 2027,” said George Magrath, M.D., Chief Executive Officer of Opus Genetics. “Based on recent FDA interactions, we finalized the OPGx-LCA5 registrational trial design. We have completed enrollment and expect to initiate participant dosing in the fourth quarter of this year. Our recent R&D Science Forum highlighted the significant progress we have made in advancing our pipeline. Our strong cash runway into 2029 positions us to initiate new clinical studies, deliver multiple data inflection points, pursue potential product approvals, and unlock opportunities for Priority Review Vouchers.”

Pipeline Updates

OPGx-BEST1

• Enrollment was completed in Cohort 1 of the Phase 1/2 trial (BIRD-1), with 3-month topline data from Cohort 1 expected during the second week of September 2026, assuming all participants complete their assessments as scheduled.
• 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 OPGx-BEST1 Program section of the Opus Genetics website.

OPGx-LCA5

• Alignment was achieved with the U.S. Food and Drug Administration (FDA) on the registrational Phase 3 clinical trial evaluating OPGx-LCA5 in eight participants with a six-month run-in period, allowing each participant to serve as their own control, prior to receiving treatment in both eyes.
• Enrollment in the trial was completed, with dosing of OPGx-LCA5 expected to begin in the fourth quarter of 2026 using clinical drug supply manufactured with the intended commercial processes. Topline data from the study is expected by the end of 2027.

OPGx-RDH12

• The OPGx-RDH12 program is expected to enter the clinic in the fourth quarter of 2026 and is partially funded through a partnership with the RDH12 Alliance.
  

OPGx-MERTK

• The OPGx-MERTK program is expected to initiate clinical testing at the Cleveland Clinic Abu Dhabi in the first quarter of 2027.
  

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).
• The OPGx-RHO program is expected to initiate clinical testing globally in the second half of 2027.

Financial Results for the Second Quarter Ended June 30, 2026

Cash Position: As of June 30, 2026, Opus Genetics had cash and cash equivalents of $88.8 million. With the current cash and cash equivalents, and potential future fundings under the note purchase agreement 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 $0.8 million for the quarter ended June 30, 2026, compared to $2.9 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 $11.2 million for the quarter ended June 30, 2026, compared to $6.0 million for the same period in 2025. The increase was primarily attributable to higher manufacturing and clinical costs associated with the Company's IRD programs, partially offset by lower clinical costs associated with the Phentolamine Ophthalmic Solution 0.75% programs. Research and development expenses included $0.4 million and $0.3 million in stock-based compensation expense for the three months ended June 30, 2026 and 2025, respectively.

General and Administrative (G&A) Expenses: G&A expenses were $6.0 million for the quarter ended June 30, 2026, compared to $5.8 million for the same period in 2025. The increase was primarily attributable to higher employee compensation costs, partially offset by lower public company related costs. General and administrative expenses included $1.0 million and $0.6 million in stock-based compensation expense during the three months ended June 30, 2026 and 2025, respectively.

Net Loss: Net loss for the quarter ended June 30, 2026 was $8.1 million, or ($0.08) per basic and ($0.14) per diluted share, compared to a net loss of $7.4 million, or ($0.12) per basic and diluted share, for the same period in 2025. The increase in net loss was primarily due to higher R&D expense, lower license and collaborations revenue, and higher financing costs period over period. These changes were partially offset by higher income period over period of $6.3 million from the fair value change in instruments measured at fair value.
