HORIZON Trial Summary

This trial will test a new gene therapy for X-linked retinitis pigmentosa, a degenerative eye disease.

Who is the study for?
This trial is for males aged 6-50 with X-linked retinitis pigmentosa (XLRP) due to RPGR gene mutations. Participants must have a certain level of visual acuity, not better than 20/32 and no worse than 20/200. They should not have other retinal diseases or previous AAV gene therapy treatments.Check my eligibility
What is being tested?
The study tests the safety and effectiveness of rAAV2tYF-GRK1-RPGR, a genetic treatment delivered via a virus vector, in patients with XLRP caused by specific RPGR mutations.See study design
What are the potential side effects?
While the side effects are not specified here, similar gene therapies can cause immune reactions, eye irritation or discomfort, changes in vision, headache or mild pain.
