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.

Webcast and conference call today at 8:00 a.m. ET with management and Key Opinion Leader and retinal specialist, Mark Pennesi, M.D., PhD.
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.
About Opus Genetics
Opus Genetics is a clinical-stage biopharmaceutical company developing gene therapies to restore vision and prevent blindness in patients with inherited retinal
diseases (IRDs). The Company is developing durable, one-time treatments designed to address the underlying genetic causes of severe retinal disorders. The Company’s pipeline includes seven AAV-based programs, led by OPGx-LCA5 for LCA5-related
mutations and OPGx-BEST1 for BEST1-related retinal degeneration, with additional candidates targeting RDH12, MERTK, RHO, CNGB1 and NMNAT1. The Company is based in Research Triangle Park, NC. For more information, visit www.opusgtx.com.
