| Arm | Type | Description |
|---|---|---|
| Dose Group 1 | EXPERIMENTAL | A 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 2 | EXPERIMENTAL | A 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 3 | EXPERIMENTAL | A 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 Observational | NO_INTERVENTION | Part 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. |
