Gene therapy for a common cause of blindness.
Preclinical evaluation of a homing endonuclease gene therapy for adRP in models of P23H retinopathy.
This study is testing a new gene therapy to help people with a specific type of inherited vision loss called autosomal dominant Retinitis pigmentosa, focusing on a common genetic change, and it aims to see if this treatment can stop vision loss and keep the eyes healthy.

What this research studies
This research investigates a novel gene therapy approach to treat autosomal dominant Retinitis pigmentosa (adRP), specifically targeting the P23H mutation in the rhodopsin gene. Using a meganuclease genome editing tool, the therapy aims to correct the genetic defect in preclinical animal models, particularly in pigs that closely resemble human retinal structure. The treatment involves delivering the gene-editing tool via subretinal injection and assessing its effectiveness in halting retinal degeneration and preserving vision. The study will also evaluate the safety of the approach by ensuring it does not cause unintended genetic changes.
Who could benefit from this research
Good fit: Ideal candidates for this research are individuals diagnosed with autosomal dominant Retinitis pigmentosa, particularly those with the P23H mutation.
Not a fit: Patients with other forms of retinal degeneration or those without the P23H mutation in the rhodopsin gene may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to a groundbreaking treatment that halts or reverses vision loss in patients with adRP.
How similar studies have performed: While gene therapy for retinal diseases is an emerging field, this specific approach using meganuclease editing for the P23H mutation is novel and has not been extensively tested in clinical settings.
