Summary

"This trial is testing a new drug called OCU400 in 150 patients with retinitis pigmentosa (RP) caused by RHO mutations or other RP-associated mutations. The study will evaluate how

Who is the study for?
This trial is for individuals with Retinitis Pigmentosa, specifically those with RHO mutations or other RP-associated mutations. It's a large study involving multiple centers and will include 150 participants.
What is being tested?
The trial is testing the efficacy, safety, and tolerability of OCU400 gene therapy administered under the retina. The study design involves randomly assigning patients to receive this treatment while keeping assessors blind to who receives what.
What are the potential side effects?
While specific side effects are not listed here, gene therapies like OCU400 may cause immune reactions, eye discomfort or damage at the injection site, changes in vision, and potential unknown long-term effects.
