Dose-escalation Study to Evaluate the Safety and Tolerability of GS030 in Subjects With Retinitis Pigmentosa
Bu Faz 1/2 (Phase 1/2) çalışma, sendromik olmayan retinitis pigmentosa (Retinitis Pigmentosa, RP) tanısı belgelenmiş kişilerde, tek doz göz içi (intravitreal) enjeksiyonla verilen GS030-DP adlı gen tedavisinin artan dozlarının ve GS030-MD adlı tıbbi cihazla (uyarıcı gözlük) yapılan tekrarlayan ışık uyarımının güvenliğini ve tolere edilebilirliğini değerlendirmektedir. Çalışma GenSight Biologics tarafından yürütülmektedir. Katılım için onam formunun imzalandığı tarihte 18-75 yaş arası olmak ve öykü, orta periferik görme bozukluğu, fundus görünümü ile tam alan incelemesi temelinde doğrulanmış sendromik olmayan RP tanısı gerekmektedir.

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, epiretinal membrane, macular pucker and macular hole, evident by ophthalmoscopy and/or by SD-OCT examinations and assessed by the investigator to significantly affect central vision. * Current evidence of retinal detachment assessed by the investigator to significantly affect central vision. * Active ocular inflammation or recurrent history of idiopathic or autoimmune associated uveitis. * Presence of an Active Implantable Medical Device. * Subjects who have undergone thermal laser procedure to the retina within 3 months of trial entry, or any prior thermal laser procedure to the macular region.
