Research summary
This is a study designed to study the effectiveness, safety and tolerability of QR-421a in different dose levels in the participants with early to moderate vision loss due to mutations in exon 13 USH2A gene. QR-421a is designed to specifically target mutations in exon 13 of USH2A gene which cause the Retinitis Pigmentosa (RP) and to overcome the genetic defect in the DNA and to restore this important protein, which may stop some effects of RP, or possibly reverse some effects.
This study will compare the effects of QR-421a with the effects of a sham procedure. The study drug will be injected into the participant’s eye (Intravitreal (IVT) Injection). Approximately 120 patients are planned to be recruited for this study worldwide. Participants will be 12 years or older.REC name
