OPGx-LCA5 is designed to address vision loss due to Leber congenital amaurosis associated with mutations in the LCA5 gene, which causes one of the most severe early-onset retinal dystrophies
Company’s first product candidate from robust pipeline of gene therapies for inherited retinal diseases advances into clinic
Research Triangle Park, N.C. – September 7, 2023 – Opus Genetics, a patient-first, clinical-stage gene therapy company developing treatments for inherited retinal diseases, today announced that the first patient has been dosed in its Phase 1/2, first-in-human clinical trial of OPGx-LCA5, an adeno-associated virus 8 (AAV8) vector designed to precisely deliver a functional LCA5 gene to the outer retina in patients with Leber congenital amaurosis (LCA) resulting from biallelic mutations in the LCA5 gene (LCA5).
LCA5 is an early-onset retinal degeneration that affects approximately one in 1.7 million people in the U.S. Currently, there are no approved treatments for individuals with LCA5-related vision loss.
“Dosing our first patient establishes Opus as a clinical-stage company and is a point of progress in our mission to advance first-in-class gene therapies for inherited retinal diseases,” said Ben Yerxa, Ph.D., chief executive officer of Opus. “Despite the severe retinal dysfunction in patients with LCA5, preclinical data suggest an opportunity for therapeutic intervention, including retinal structural and functional restoration when OPGx-LCA5 was administered prior to peak disease severity. We look forward to progressing the trial of this potentially transformative therapy for patients affected by LCA5.”
The Phase 1/2, open-label, dose-escalation trial is evaluating the subretinal delivery of OPGx-LCA5 in nine adult patients with LCA5. The objective of the trial is to evaluate the safety and preliminary efficacy of OPGx-LCA5 in patients with inherited retinal degeneration due to biallelic mutations in the LCA5 gene.
Once safety in adults has been established and confirmed by the FDA, Opus plans to add a pediatric cohort.

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 is an early-onset severe inherited retinal dystrophy. Studies in LCA5 patients 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. Preclinical data, including animal and human iPSC models, have demonstrated preservation of retinal structure and visual function when OPGx-LCA5 was administered prior to peak disease severity.
