Executive Summary
- Opus Genetics' OPGx-LCA5 gene therapy shows durable efficacy in improving vision for patients with Leber congenital amaurosis (LCA5) after one year.
- The FDA granted OPGx-LCA5 a Regenerative Medicine Advanced Therapy (RMAT) designation, facilitating its development and review.
- Clinical trial data indicates improvements in cone-mediated vision, reading ability, object recognition, and retinal sensitivity.
Event Overview
Opus Genetics, a clinical-stage ophthalmic biotechnology company, is developing gene therapies for inherited retinal diseases (IRDs). Its lead candidate, OPGx-LCA5, is designed to treat Leber congenital amaurosis (LCA5) caused by mutations in the LCA5 gene. Recent one-year results from the Phase 1/2 study of OPGx-LCA5 demonstrate sustained improvements in vision for adult patients. Further, the FDA has granted OPGx-LCA5 a Regenerative Medicine Advanced Therapy (RMAT) designation, which will help expedite its development and review. The company also plans to initiate a registration trial in 2026 after discussions with the FDA regarding trial design.

Key Details & Data Points
- What: OPGx-LCA5 is a gene therapy designed to treat Leber congenital amaurosis (LCA5), an inherited retinal disease, by delivering a functional copy of the LCA5 gene.
- Who: Opus Genetics, patients with LCA5-related inherited retinal degeneration, Dr. Tomas Aleman of the Scheie Eye Institute, University of Pennsylvania, and the FDA.
- When: One-year results presented at ARVO 2025 (May 4-7, 2025). RMAT designation granted in May 2025. Phase 1/2 trial initiated in 2023.
- Where: Clinical trial conducted at the University of Pennsylvania. ARVO meeting held in Salt Lake City, Utah.
Key Statistics:
- Visual Acuity: Average improvement of 0.35 logMAR (equivalent to 3.5 lines) across three participants.
- Full-field Stimulus Testing: 0.86 log improvement in retinal sensitivity at 12 months vs 0.16 log units for the control eyes.
- Analyst average target price: $14.75, implying an upside of 1,445.47% from the current price of $0.95 (GuruFocus).
Analysis & Context
The one-year results from the Phase 1/2 trial of OPGx-LCA5 are promising, demonstrating durable efficacy in improving visual function in patients with LCA5. The FDA's RMAT designation is a significant milestone, potentially accelerating the development and approval of this gene therapy. This designation highlights the potential of OPGx-LCA5 to address a serious unmet need in patients with this ultra-rare and debilitating form of inherited blindness. The participation in the FDA’s CDRP program will further streamline development.
Notable Quotes
The preliminary data emerging from this Phase 1/2 study of OPGx-LCA5 are very encouraging. We are pleased to see evidence of durable efficacy, with the treatment benefits observed at six months being sustained out to one year.
The FDA’s decision to grant RMAT designation to OPGx-LCA5 is a major milestone for the LCA5 patient community and a strong validation of our early clinical data.
Conclusion
Opus Genetics' OPGx-LCA5 gene therapy shows significant promise for treating Leber congenital amaurosis (LCA5), with positive one-year clinical trial results and FDA RMAT designation. These developments indicate a potential for improved treatment options for patients with this inherited retinal disease, and ongoing studies will further evaluate the therapy's long-term efficacy and safety. Opus Genetics is planning to start the registration trial in 2026, after discussing with the FDA regarding the trial design.
