LCA5

LCA5 (Lebercilin)

Lebercilin; involved in ciliary transport in photoreceptors

Active Clinical Trials

Opus Genetics OPGx-LCA5 (OPGx-001) Phase 1/2 (NCT05616793) at UPenn — subretinal AAV8 carrying human LCA5 cDNA. One-year adult results showed recovery of cone-mediated vision (~1 log unit; Aleman et al., Mol Ther 2025), and an adolescent cohort showed similar early gains with good tolerability (ARVO 2026). Pivotal trial planned, dosing anticipated H2 2026.
