X-Linked Retinoshisis (RS1) Gene Therapy Trial
A Multiple-Site, Phase 1/2, Safety and Efficacy Trial of a Recombinant Adenoassociated Virus Vector Expressing Retinoschisin (rAAV2tYF-CB-hRS1) in Patients With X-linked Retinoschisis
The purpose of this study is to learn about a new gene therapy that may help patients with X-Linked Retinoschisis (XLRS). This is the first study that aims to treat XLRS disease by gene therapy. The study investigators want to find out whether it is safe for use in humans. The gene therapy is given by a surgical injection into the vitreous (a thick, gel-like transparent substance that fills the center of the eye) of one eye. The eye with worse vision will receive the gene therapy.
- Ages 6-17 years for Group 2A. Ages 6 years and older for Group 4 (Groups 1A, 1B, 2, and 3 have been fully enrolled).
- Must have a documented mutation in the RS1 gene, which is the gene linked to XLRS.
- Must have visual acuity no better than:
- 20/80 in the eye that will receive gene therapy for Group 1A
- 20/63 in the eye that will receive gene therapy for Group 1B, 2, 2A, and 3
- 20/50 in the eye that will receive gene therapy for Group 4
- Good general health
