Opus Genetics, a patient-first, clinical-stage gene therapy company developing treatments for inherited retinal diseases, today announced the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease designation (RPD) for its ocular gene therapy OPGx-LCA5 to treat patients with the inherited retinal disease LCA5.
OPGx-LCA5 is 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).
“We are thrilled to receive Rare Pediatric Disease designation from the FDA for our OPGx-LCA5 gene therapy. This important milestone brings us closer to delivering a potential treatment for patients with LCA5,” said Ben Yerxa, PhD, CEO of Opus. “At Opus, we’re committed to advancing therapies that help treat patients with inherited retinal diseases, and this designation further validates the potential impact of our innovative ocular gene therapy approach. We look forward to providing updates on the Phase 1/2 clinical trial evaluating OPGx-LCA5 soon.”
LCA5 is a form of 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.
OPGx-LCA5 is currently being studied in an open-label, dose-escalation Phase 1/2 clinical trial at the University of Pennsylvania designed to evaluate its safety and preliminary efficacy in 15 patients with inherited retinal degeneration due to biallelic mutations in the LCA5 gene. For more information on the trial, visit clinicaltrials.gov (NCT05616793).
The FDA grants Rare Pediatric Disease designation to therapeutics intended to treat serious or life-threatening rare diseases that primarily affect individuals under the age of 18.
By obtaining this designation, Opus has access to valuable incentives and support from the FDA during its development program. With this designation, OPGx-LCA5 will be eligible to receive a priority review voucher upon approval for any subsequent marketing application that can be sold or transferred to other companies.
About OPGx-LCA5
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. OPGx-LCA5 is currently being evaluated in a Phase 1/2 clinical trial at the University of Pennsylvania designed to evaluate its safety and preliminary efficacy in 15 patients with inherited retinal degeneration due to biallelic mutations in the LCA5 gene.
