Natural History of Patients With Inherited Retinal Diseases Due to Mutations in RPE65 Gene
Italy60 participantsStarted 2020-05-01
Plain-language summary
Rationale:
In preparation for treatment with gene therapy, this study is being conducted in order to investigate the natural history of Inherited Retinal Dystrophies (IRDs) due to mutations in RPE65 gene. Such a study will help identify suitable patients for therapeutic intervention.
Methodology:
This is a multicenter retrospective, descriptive chart review study designed to assess retinal structure and function in subjects with IRDs due to mutation in RPE65 gene by visual acuity, visual field measurements, Optical Coherence Tomography (OCT), and a number of other vision-related assessments.

* Molecular diagnosis showing mutations (homozygotes or compound heterozygotes) in RPE65 gene.
* Age three years old or older.
* Minimum of two office / clinic visits encounters with ophthalmic assessment that span a follow-up period of at least 1 year with the last visit occurring within the last six months (before signature of informed consent and of study start).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
