T1 Mapping in Fabry Disease

France70 participantsStarted 2023-08-07

Plain-language summary

Fabry disease (OMIM-301500, FD) is a lysosomal storage disease with X-linked inheritance secondary to mutations in the α-galactosidase A gene (GLA), which cause absence or decreased activity of the lysosomal hydrolase a-galactosidase A (a-gal A). The accumulation of globotriaosylceramide (Gb3) leads to multiple organs dysfunction, especially in three key organs: kidney, heart and cerebrovascular system. Progressive nephropathy is one of the main features of Fabry disease and is marked by an insidious development. The investigators are facing different current challenges about treatment initiation in non-classic phenotype patients, optimal dose after treatment initiation, and treatments monitoring in Fabry nephropathy. That is even more important that the enzyme replacement therapy is expensive and a lifelong commitment. Functional magnetic resonance imaging (MRI) is now able to provide T1 mapping sequence. In Fabry disease, T1 mapping is currently used to assess the degree of myocardial involvement. The MRI for assessement of Fabry Cardiomyopathy is now recommended by the 2022 national diagnostic and care protocol (PNDS) in France. However there is no data about T1 mapping values in kidney in Fabry's disease The main Objective is to describe renal performance through multi-parametric MRI in Fabry nephropathy and the primary outcome will be the quantification of renal T1 in Fabry patients.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
