Treatment Arms

ArmTypeDescription
Dose Group 1EXPERIMENTALA single, unilateral, subretinal injection of low dose (1E10 vg/eye) OPGx-001 is injected into two LCA5 adults (18 yo or above) in a sentinel fashion. A 30-day safety evaluation and data committee review and approval of continued dosing occurs. If additional dosing is recommended, a subsequent LCA5 adolescent (13-17) may be treated in a sentinel fashion, with a unilateral, subretinal injection of OPGx-001. A 30-day safety evaluation and data committee review and approval of continued dosing occurs. If additional dosing is recommended, two remaining adolescents (13-17) are eligible to be treated with a single, unilateral, subretinal injection of a low dose of OPGx-001. Total cohort size is 5 (2 adults and 3 adolescents).
Dose Group 2EXPERIMENTALA single, unilateral, subretinal injection of an intermediate dose (3E10 vg/eye) OPGx-001 is injected into two LCA5 adults (18 yo or above) in a sentinel fashion. A 30-day safety evaluation and data committee review and approval of continued dosing occurs. If additional dosing is recommended, a subsequent LCA5 adolescent (13-17) may be treated in a sentinel fashion, with a unilateral, subretinal injection of OPGx-001. A 30-day safety evaluation and data committee review and approval of continued dosing occurs. If additional dosing is recommended, two remaining adolescents (13-17) are eligible to be treated with a single, unilateral, subretinal injection of an intermediate dose of OPGx-001. Total cohort size is 5 (2 adults and 3 adolescents).
Dose Group 3EXPERIMENTALA single, unilateral, subretinal injection of high dose (1E11 vg/eye) OPGx-001 is injected into two LCA5 adults (18 yo or above) in a sentinel fashion. A 30-day safety evaluation and data committee review and approval of continued dosing occurs. If additional dosing is recommended, a subsequent LCA5 adolescent (13-17) may be treated in a sentinel fashion, with a unilateral, subretinal injection of OPGx-001. A 30-day safety evaluation and data committee review and approval of continued dosing occurs. If additional dosing is recommended, two remaining adolescents (13-17) are eligible to be treated with a single, unilateral, subretinal injection of a high dose of OPGx-001. Total cohort size is 5 (2 adults and 3 adolescents).
Part B ObservationalNO_INTERVENTIONPart B will occur concurrently with Dose Groups 1-3. Sixteen patients will be assessed for 6 months to assess the natural course of LCA5-IRD, then will be treated with OPGx-001 which will be described in a future protocol amendment.

Frequently asked questions about OPGx-LCA5

What is OPGx-LCA5 used for?

OPGx-LCA5 is an investigational gene therapy being developed for LCA5-associated inherited retinal degeneration, a rare genetic form of vision loss caused by mutations in the LCA5 gene. It is designed to treat patients with this specific inherited retinal disease. It is not approved for any use and remains in clinical development.

Who makes OPGx-LCA5?

OPGx-LCA5 is being developed by Opus Genetics, Inc., a clinical-stage biopharmaceutical company focused on gene therapies for inherited retinal diseases. Opus Genetics trades on the Nasdaq under the ticker symbol IRD.

What phase is OPGx-LCA5 in?

OPGx-LCA5 is in Phase 1 clinical development. The program has one active, recruiting trial and no completed trials. It is investigational and has not been approved by the FDA for any indication.

What clinical trials is OPGx-LCA5 in?

OPGx-LCA5 is being evaluated in a single Phase 1 trial, NCT05616793, titled a study of safety and tolerability of subretinal OPGx-001 for LCA5-associated inherited retinal degeneration. The trial is recruiting in the United States, has an estimated enrollment of 22 participants, and includes a non-interventional arm with untreated patients.

Is OPGx-LCA5 the same as AAV8.hLCA5?

Yes, AAV8.hLCA5 is another name for OPGx-LCA5. Both refer to the same investigational gene therapy developed by Opus Genetics for LCA5-associated inherited retinal degeneration.

What FDA designations has OPGx-LCA5 received?

OPGx-LCA5 has received three FDA designations: Rare Pediatric Disease designation, Regenerative Medicine Advanced Therapy (RMAT) designation, and Orphan Drug designation. These designations are intended to support and expedite the development of therapies for serious rare conditions.
