Rhea-AI Filing Summary

Opus Genetics, Inc. (IRD) reported interim 3‑ and 6‑month data from low‑dose Cohort 1 of its Phase 1/2 BIRD‑1 trial of gene therapy OPGx‑BEST1 in BEST1‑related retinal diseases. Five adults received 1.5 x 10⁹ vg/eye; all showed clinically meaningful improvement in at least one visual‑function measure, and four showed structural retinal improvements.

OPGx‑BEST1 was well tolerated, with no serious adverse events, dose‑limiting toxicities or intraocular inflammation; all treatment‑related events were mild or moderate. Functional gains included BCVA improvement in 60% of participants, and microperimetry improvements in 75% of evaluable participants, concentrated in the treated retinal transitional zone. Based on these proof‑of‑concept results, Opus has advanced to a higher‑dose Cohort 2 (4.5 x 10⁹ vg/eye), over‑enrolled to eight participants, with dosing expected to complete in Q4 2026 and topline three‑month data expected in Q2 2027. Following an August 2026 FDA Type C meeting, Opus and the FDA aligned on a potential pivotal endpoint using ≥3 dB microperimetry improvement in ≥5 prespecified loci with a patient‑reported outcome, and Opus expects to plan Phase 3 dosing in 2027. New research estimates about 23,600 symptomatic BEST1 patients in the U.S. and 45,400 globally, and the company states its cash runway extends into 2029.

Positive

  • 100% of Cohort 1 participants showed clinically meaningful improvement in at least one visual‑function measure, providing early proof‑of‑concept for OPGx‑BEST1 in BEST1‑related retinal disease.
  • OPGx‑BEST1 showed a favorable safety profile in Cohort 1 with no serious adverse events, no dose‑limiting toxicities and no intraocular inflammation, supporting advancement to a higher‑dose cohort.
  • Opus aligned with the FDA on a potential pivotal endpoint based on ≥3 dB microperimetry improvement in ≥5 loci plus a patient‑reported outcome, clarifying the regulatory path toward Phase 3.
  • Management states its cash runway extends into 2029, supporting multiple clinical readouts, including BEST1 Phase 1/2 Cohort 2 data and planned pivotal development.
  • New epidemiology work estimates about 23,600 symptomatic BEST1 patients in the U.S. and 45,400 globally, suggesting a substantially larger addressable market than previously estimated.

Negative

  • None.

Filing Explained

The press release says cash runway extends into 2029, but the latest reported $88,812,000 of cash and $11,950,000 quarterly operating cash outflow equal 676.3 days of that historical use rate; those figures provide a quantified liquidity period rather than establishing funding through 2029.

Sources and calculations
  • Available liquidity against the last reported quarterly operating outflow, in days at that rate $88,812,000 / ($11,950,000 / 91) = 676.3 days

microperimetry medical
"clinically meaningful improvement in retinal sensitivity by microperimetry"
Microperimetry is a clinical eye test that maps how well specific spots on the retina detect light while tracking their exact location on an image of the back of the eye. For investors, it matters because it provides precise, location-specific evidence of vision improvement or decline in drug and device trials, affecting regulatory decisions, market potential and reimbursement—think of it as a high-resolution measuring stick for retinal function.
best-corrected visual acuity medical
"measured as one or more of the following: best-corrected visual acuity (BCVA)"
The sharpest level of sight a person can reach when using the best possible glasses or contact lenses; think of it as how well a camera can resolve detail once its lens is perfectly focused. It matters to investors because it is a common clinical measure and regulatory endpoint for eye drugs, procedures and devices, so changes in best-corrected visual acuity indicate whether a treatment works and can drive approval, market size and sales potential.
dose-limiting toxicities medical
"no serious adverse events or dose-limiting toxicities"
Dose-limiting toxicities are the harmful side effects seen in early clinical trials that are severe enough to stop researchers from raising a drug’s dose. Like a car’s speed limiter marking the safe top speed, DLTs define the maximum tolerable dose, and they matter to investors because they determine whether a medicine can reach effective levels, influence development timelines, costs, and regulatory chances, and thus affect a drug’s commercial prospects.
vitelliform material medical
"reductions in vitelliform material, the hallmark of BVMD"
Priority Review Voucher regulatory
"have the potential to qualify for a Priority Review Voucher"
A priority review voucher is a transferable regulatory incentive that lets a company move a future drug or device application to the front of the review line, shortening the review period by several months. For investors it matters because the voucher can speed up market access for a high-value product or be sold to other companies for significant cash, acting like a tradable fast-pass that can accelerate revenue or create immediate financial upside.
Type C meeting regulatory
"successful FDA Type C Meeting with Potential Phase 3 Dosing"

Item 7.01
Regulation FD Disclosure.
 
On September 9, 2026, Opus Genetics, Inc. (the “Company”) issued a press release and held an investor conference announcing clinical data from Cohort 1 of the Company’s ongoing Phase 1/2 clinical trial of OPGx-BEST1 in patients with BEST1-related retinal diseases, including best vitelliform macular dystrophy (“BVMD”) and autosomal recessive bestrophinopathy (“ARB”). A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K. A copy of the data presentation used in connection with the investor conference is furnished as Exhibit 99.2 to this Current Report on Form 8-K.
 
The information in this report is furnished pursuant to Item 7.01, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01
Other Events.
 
On September 9, 2026, the Company shared 3- and 6-month results from the low-dose Cohort 1 of BIRD-1, the Company’s ongoing Phase 1/2 clinical trial of OPGx-BEST1 in patients with BEST1-related retinal diseases, including BVMD and ARB. Cohort 1 enrolled five participants treated at 1.5 x 10⁹ vg/eye: three participants with BVMD who have reached three months of follow-up and two participants with ARB who have reached six months of follow-up. Following treatment with OPGx-BEST1, all five participants demonstrated clinically meaningful improvement in visual function, measured as one or more of the following: best-corrected visual acuity (“BCVA”), low-luminance visual acuity (“LLVA”), contrast sensitivity (“CS”) or microperimetry, an advanced eye test that maps how well the central part of the retina sees light. Structural improvements were also observed across four participants.

OPGx-BEST1 demonstrated a favorable safety and tolerability profile, with no serious adverse events or dose-limiting toxicities, no intraocular inflammation and no vital-sign or safety-laboratory findings of note. All treatment-related adverse events were mild or moderate in severity. BCVA improved in 60% of participants (3/5), LLVA improved in 40% of participants (2/5), and contrast sensitivity improved in 40% of participants (2/5). Among evaluable participants, 75% (3/4) demonstrated clinically meaningful improvement in retinal sensitivity by microperimetry. Importantly, these gains were concentrated in the treated retinal pigment epithelial Transitional Zone, where viable photoreceptors remain, with the greatest functional improvements observed in participants with less advanced disease. Structural improvements were observed in four of five participants, with reductions in vitelliform material, the hallmark of BVMD, in 67% of participants with BVMD (2/3) and reductions in intraretinal fluid in 100% of participants with ARB (2/2). The third BVMD participant had possible, but not definitive, reduction in vitelliform material.

Based on the safety profile and positive proof-of-concept findings from Cohort 1, the Company has advanced to the higher-dose Cohort 2, evaluating OPGx-BEST1 at 4.5 x 10⁹ vg/eye, with dosing expected to be complete in the fourth quarter of 2026 and topline three-month data expected to be available in the second quarter of 2027. Originally designed to enroll five participants, Cohort 2 has been over-enrolled with eight participants, most of whom have BVMD. Data from Cohort 2 are expected to further characterize the safety, functional and structural responses to OPGx-BEST1 at the higher dose and inform the design of a potential pivotal clinical trial.

In addition, the Company announced that in August 2026, the Company met with the U.S. Food and Drug Administration (“FDA”) to discuss OPGx-BEST1 development and potential endpoints for a pivotal clinical trial. The Company aligned with the FDA on a potential pivotal endpoint based on ≥3 dB microperimetry improvement in ≥5 prespecified loci, in conjunction with a patient-reported outcome in a randomized, controlled trial. BCVA, LLVA and CS may also be acceptable endpoints​. The Company also aligned with the FDA on Phase 3 and commercial manufacturing requirements, which it expects to complete in early 2027. The Company currently expects to begin planning for participant dosing in the Phase 3 clinical trial in 2027.

Finally, new epidemiology research estimates approximately 23,600 symptomatic BEST1 patients in the U.S., including 13,000 diagnosed and 10,600 undiagnosed patients, and approximately 45,400 symptomatic BEST1 patients globally.

RESEARCH TRIANGLE PARK, N.C. - 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 positive 3- and 6-month results from the low-dose Cohort 1 of BIRD-1, its ongoing Phase 1/2 clinical trial evaluating OPGx-BEST1 in patients with BEST1-related retinal diseases, including Best vitelliform macular dystrophy (BVMD) and autosomal recessive bestrophinopathy (ARB).
 

Cohort 1 enrolled five participants treated at 1.5 x 10⁹ vg/eye: three participants with BVMD who have reached three months of follow-up and two with ARB who have reached six months of follow-up. All five participants demonstrated clinically meaningful improvement in visual function, measured as one or more of the following: best-corrected visual acuity (BCVA), low-luminance visual acuity (LLVA), contrast sensitivity (CS) or microperimetry, an advanced eye test that maps how well the central part of the retina sees light. Structural improvements were also observed across four participants. The greatest functional gains were observed in participants with less advanced disease, supporting the potential benefit of treating patients while viable retinal tissue remains. The Company expects to announce 6-month data for the three participants with BVMD in Q2 2027.
 
“These positive results provide important evidence of OPGx-BEST1’s potential to improve both visual function and retinal structure in patients with BEST1-related retinal disease, which we believe has a significantly larger underserved patient population than we previously thought,” said George Magrath, M.D., Chief Executive Officer of Opus Genetics. “The functional and structural improvements across Cohort 1, particularly the greater functional gains observed in patients with viable retinal tissue, reinforce our confidence in OPGx-BEST1’s potential to have a positive impact on the lives of patients with BEST disease. Together with our recent FDA interaction and rapid enrollment of Cohort 2, we believe these data provide a clear path toward pivotal development, which we plan to begin next year. We want to recognize the contributions of our investigators, clinical teams, and most importantly, the patients helping advance a potential treatment for this blinding disease.”
 
“These Cohort 1 data provide encouraging evidence that OPGx-BEST1 can be delivered safely and may improve both retinal structure and visual function in patients with advanced BEST1-related retinal disease,” said Christine Nichols Kay, M.D., clinical trial investigator and Director of Clinical Research and Retinal Genetics at Vitreo Retinal Associates.
 
“We are encouraged by the localization of functional gains to areas of viable, but compromised retina and by the opportunity to apply these insights prospectively as OPGx-BEST1 is advanced into Cohort 2 and potential pivotal development,” said Mark Pennesi, M.D., Ph.D., clinical trial investigator and Chief Medical Officer at the Retina Foundation and Adjunct Professor of Ophthalmology, Casey Eye Institute, Oregon Health & Science University. “From a regulatory perspective, it is particularly exciting to align with the FDA on a >3 decibels change from baseline in microperimetry anchored to patient reported outcomes as a potential pivotal endpoint.”
 
OPGx-BEST1 demonstrated a favorable safety and tolerability profile, with no serious adverse events or dose-limiting toxicities, no intraocular inflammation and no vital-sign or safety-laboratory findings of note. All treatment-related adverse events were mild or moderate in severity.
 

All five participants demonstrated clinically meaningful improvement in visual function following treatment with OPGx-BEST1. BCVA improved in 60% of participants (3/5), LLVA improved in 40% of participants (2/5), and contrast sensitivity improved in 40% of participants (2/5). Among evaluable participants, 75% (3/4) demonstrated clinically meaningful improvement in retinal sensitivity by microperimetry. Importantly, these gains were concentrated in the treated retinal pigment epithelial (RPE) Transitional Zone, where viable photoreceptors remain, with the greatest functional improvements observed in participants with less advanced disease.
 
Structural improvements were observed in four of five participants, with reductions in vitelliform material, the hallmark of BVMD, in 67% of participants with BVMD (2/3) and reductions in intraretinal fluid in 100% of participants with ARB (2/2). The third BVMD participant had possible, but not definitive, reduction in vitelliform material. These findings provide proof-of-concept that OPGx-BEST1 may improve visual function and retinal structure in areas where viable retinal tissue remains and are informing patient selection and future clinical development.
 
In BVMD, vitelliform material accumulates early and is the defining structural feature of the disease, while subretinal fluid appears late and pools in areas of established atrophy. Reduction of vitelliform material is therefore the more direct measure of restored RPE function in this population, and it is the structural change that corresponded with functional improvement in those participants. In ARB, where intraretinal fluid is the dominant structural manifestation, fluid reduction was substantial and consistent in both participants.
 
In August 2026, the Company met with the U.S. Food and Drug Administration (FDA) to discuss OPGx-BEST1 development and potential endpoints for a pivotal clinical trial. The Company aligned with the FDA on a potential pivotal endpoint based on ≥3 dB microperimetry improvement in ≥5 prespecified loci, in conjunction with a patient-reported outcome in a randomized, controlled trial. BCVA, LLVA, and CS may also be acceptable endpoints​. The Company also aligned with the FDA on Phase 3 and commercial manufacturing requirements, which it expects to complete in early 2027. The Company expects to begin planning for the Phase 3 trial immediately, with participant dosing expected to begin in 2027.
 
Based on the safety profile and positive proof-of-concept findings from Cohort 1, the Company has advanced to the higher-dose Cohort 2, evaluating OPGx-BEST1 at 4.5 x 10⁹ vg/eye, with dosing expected to be completed in Q4 2026 and topline three-month data expected in Q2 2027. Originally designed to enroll five participants, Cohort 2 has been over-enrolled with eight participants, most of whom have BVMD. Data from Cohort 2 are expected to further characterize the safety, functional and structural responses to OPGx-BEST1 at the higher dose and inform the design of a potential pivotal clinical trial.
 

New epidemiology research conducted by Triangle Insights Group, based on a survey of more than 150 eye care professionals, estimates approximately 23,600 symptomatic BEST1 patients in the U.S., including 13,000 diagnosed and 10,600 undiagnosed patients, and approximately 45,400 symptomatic BEST1 patients globally. These findings suggest a substantially larger addressable patient population and unmet need than previously estimated.

About BEST1 and OPGx-BEST1
 
BEST1-related inherited retinal diseases, or bestrophinopathies, are rare forms of inherited macular degeneration caused by mutations in the BEST1 gene. These mutations disrupt the normal function of RPE cells, leading to retinal lesions, progressive degeneration and vision loss. BEST1-related diseases include BVMD and ARB, and there are currently no approved therapies that address the underlying genetic cause of these diseases.
 
OPGx-BEST1 is an investigational gene therapy designed to address the underlying genetic cause of BEST1-related inherited retinal diseases, including BVMD and ARB. OPGx-BEST1 uses an AAV vector to deliver a functional copy of the BEST1 gene to retinal pigment epithelial cells. The ongoing BIRD-1 clinical trial is an adaptive, open-label Phase 1/2 clinical trial evaluating the safety and efficacy of single-eye subretinal administration of OPGx-BEST1 in adults with BVMD or ARB.

Exhibit 99.2



 OPGx-BEST1 Gene Therapy Phase 1/2 Study Low Dose Cohort 1 3-month Results  September 9, 2026 
 

 This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by the following words: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “aim,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. Such statements include, but are not limited to, statements related to our continued clinical development, clinical results, preclinical data, and future plans for OPGx-BEST1, including the anticipated timing of dosing completion and topline data from Cohort 2 of the OPGx-BEST1 Phase 1/2 clinical trial; the outcome of our ongoing regulatory interactions with the U.S. Food and Drug Administration (the “FDA”) and our expectations regarding the design of, and potential endpoints for, of any pivotal clinical trial of OPGx-BEST1; our expectations regarding the clinical and therapeutic potential of OPGx-BEST1, including with respect to its ability to improve visual function and retinal structure in patients with BEST1-related retinal disease; our estimates of the BEST1 symptomatic patient population in the U.S. and globally; and our expectations regarding our company, its business prospects, and our results of operations. These forward-looking statements are subject to certain risks and uncertainties posed by many factors and events that could cause our actual business, prospects and results of operations to differ materially from those anticipated by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to: our clinical data related to gene therapies for the treatment of inherited retinal diseases is preliminary and related to a relatively small group of patients, and, as a result, data that initially appears promising may be revised, updated, or invalidated at a later data readout and/or may ultimately not be capable of duplication in additional patients; our gene therapy product candidates are based on a novel technology that is difficult to develop and manufacture, which may result in delays and difficulties in obtaining regulatory approval; our planned clinical trials may face substantial delays, result in failure, or provide inconclusive or adverse results that may not satisfy the FDA requirements to further develop our therapeutic products; delays or difficulties associated with patient enrollment in clinical trials may affect our ability to conduct and complete those clinical trials and obtain necessary regulatory approvals; changes in regulatory requirements could result in increased costs or delays in development timelines; we depend heavily on the success of our product pipeline; if we fail to find strategic partners or fail to adequately develop or commercialize our pipeline products, our business will be materially harmed; we have not generated significant revenue from sales of any products and expect to incur losses for the foreseeable future; our future viability is difficult to assess due to our short operating history and our future need for substantial additional capital, access to which could be limited by any adverse developments that affect the financial services markets; we rely on third parties for material aspects of our business, such as conducting our nonclinical and clinical trials and supplying and manufacturing bulk drug substances, which exposes us to certain risks; and those risks and uncertainties described under the heading “Risk Factors” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and our subsequent filings with the U.S. Securities and Exchange Commission (the “SEC”). Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this presentation. We undertake no obligation to revise any forward-looking statements in order to reflect events or circumstances that might subsequently arise. These forward-looking statements are based upon our current expectations and involve assumptions that may never materialize or may prove to be incorrect.  Disclosures and Forward-Looking Statements  2
