Description

Summary

This is a Phase 3 study to Assess the Efficacy, Safety and Tolerability of OCU400 in patients with retinitis pigmentosa (RP) associated with RHO mutations and patients with any other RP associated mutation with a clinical phenotype of RP.

This is a multicenter, assessor blinded and randomized study which will enroll 150 subjects.

Official Title

A Phase 3, Multi-Center, Randomized Study to Assess The Efficacy, Safety and Tolerability of Subretinal OCU400 Gene Therapy for the Treatment of Retinitis Pigmentosa

Details

A total of one hundred and fifty (150) RP participants will be enrolled in this study- 75 in each of either two arms, RHO arm (n=75) or Gene agnostic arm (n=75). RHO arm will only enroll participants with confirmed genetic diagnosis of mutation in RHO gene; whereas Gene Agnostic arm will enroll RP Participants based on clinical diagnosis of RP and a confirmed genetic diagnosis with a gene associated with RP.

Subjects in each arm will be randomized into treatment (N=50) and control groups (N=25). Subjects in the treatment group will receive a sequential, bilateral sub-retinal injection of OCU400 if both eyes meet inclusion criteria. Control or untreated group subjects will receive OCU400 subretinal injection after completion of 12-month follow-up.
