Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals with a confirmed diagnosis of retinitis pigmentosa and bare light perception in at least one eye.
✕Probably not a fit
Patients who have previously received any AAV gene therapy product or have large amplitude nystagmus may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a non-randomized, open-label Phase 1/2 dose escalation study evaluating BS01, a recombinant adeno-associated virus vector designed to express an enhanced light-sensitive channelrhodopsin gene. The study aims to assess the safety and efficacy of BS01 in patients diagnosed with retinitis pigmentosa who have bare light perception in at least one eye. Participants will receive varying doses of the treatment to determine the optimal dosage for therapeutic effect.
Why it matters
Potential benefit: If successful, this treatment could restore vision or improve light sensitivity in patients with retinitis pigmentosa.
How similar studies have gone: While gene therapy for retinal conditions is an emerging field, this specific approach using BS01 is novel and has not been extensively tested in prior studies.
