Dose-escalation Study to Evaluate the Safety and Tolerability of GS030 in Subjects With Retinitis Pigmentosa

Inclusion criteria: * Age ≥18 years to ≤75 years at the time of ICF signature. * Diagnosis of non-syndromic RP defined as: * Clinical diagnosis of non-syndromic RP based on history, mid-peripheral visual dysfunction, and fundoscopic appearance. * Diagnosis of non-syndromic RP is confirmed on full-field ERG * Visual acuity: * Visual acuity in the dose-escalation cohorts of no better LP. * Visual acuity in the extension cohort of no better than CF pending review of dose-escalation cohort data by the DSMB. * Relatively preserved ganglion cell layer volume and retinal nerve fiber layer thickness, as measured with spectral domain optical coherence tomography (SD-OCT). * Interpupillary distance of ≥51 mm and ≤72 mm. * Refractive error of the study eye between -6 diopters and +6 diopters. Exclusion criteria * Prior receipt of any gene therapy. * Subjects who have undergone significant ocular surgery (per investigator determination) within 3 months prior to Visit 1. * Presence of narrow iridocorneal angles contraindicating pupillary dilation. * Presence of disorders of the ocular media which interfere with visual acuity and other ocular assessments, including SD-OCT, during the study period. * Presence of any systemic or ocular diseases, or pathologies, other than non-syndromic RP, or their associated therapies, that can cause or have the potential to cause vision loss. * Prior vitrectomy or vitreomacular surgery. * Presence of vitreo-macular adhesion or traction, epiret…
