Establishment of Biomarkers for Fabry Disease
An observational study of Fabry Disease, run by Ohio State University at 1 site in United States.
Trial summary
Fabry disease, an x-linked recessive lysosomal storage disease (LSD) is commonly recognized as a cause of renal failure in involved men and more recently recognized in women too. Women are involved in significant numbers and with complications, as are men, of vascular disease. Read more about this study

About this study
Fabry disease, an x-linked recessive lysosomal storage disease (LSD) is commonly recognized as a cause of renal failure in involved men and more recently recognized in women too. Women are involved in significant numbers and with complications, as are men, of vascular disease. This manifests as unexpected strokes in young adults. We have morphologic evidence that storage-endotheliopathy induced microvascular disease is the cause of cardiopathy and of cryptogenic strokes, and that storage endotheliopathy starts in early life, probably before birth. Based on our earlier work with other endotheliopathies such as diabetes mellitus, Susac syndrome, and hypertension, we will find and study patients using unique methods, neuro-retinal fluorescein angiography (NRFA), that we have developed for this purpose. These methods include NRFA to demonstrate capillary perfusion in the optic nerve head and retinal quadrants. We anticipate, based on our earlier experience with other endotheliopathies, that we will show more vascular pathology earlier than previously reported. Using epidemiologic and genetic tools we will find more patients than previously known or expected. It will offer opportunity for earlier diagnosis, prognosis, and response to enzyme replacement therapy.
We hypothesize that Fabry disease is a poorly recognized and poorly characterized cause of microvascular disease and cryptogenic strokes in young women and men. Neuroretinal capillary perfusion abnormalities in Fabry disease will be predictive of equivalent vascular disease in kidney, heart, brain and other organs, and further that it will be responsive to change induced by enzyme replacement therapy treatment.

Specific Aims
Specific Aim 1. To demonstrate the specificity and sensitivity of the diagnostic capabilities of a neuroretinal examination which includes slit lamp and fundoscopy, and NRFA for the diagnosis of Fabry disease on a subject population of identified FD patients.
Specific Aim 2. To show capillary perfusion abnormalities in optic nerve and retina using neuroretinal fluorescein angiography in patients with Fabry disease and compare these to renal (measured by GFR).
Specific Aim 3. To show that the change in capillary perfusion studies when compared to baseline in response to enzyme replacement therapy treatment over time, as a manifestation of tissue burden and prognosis is a more sensitive biomarker of the extent of patient disease than corneal keratopathy.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Fabry disease, an x-linked recessive lysosomal storage disease (LSD) is commonly recognized as a cause of renal failure in involved men and more recently recognized in women too. Women are involved in significant numbers and with complications, as are men, of vascular disease. This manifests as unexpected strokes in young adults. We have morphologic evidence that storage-endotheliopathy induced microvascular disease is the cause of cardiopathy and of cryptogenic strokes, and that storage endotheliopathy starts in early life, probably before birth. Based on our earlier work with other endotheliopathies such as diabetes mellitus, Susac syndrome, and hypertension, we will find and study patients using unique methods, neuro-retinal fluorescein angiography (NRFA), that we have developed for this purpose.

Using epidemiologic and genetic tools we will find more patients than previously known or expected.

Questions about this trial
What is this clinical trial studying?
An observational study of Fabry Disease, run by Ohio State University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Presence of specific findings commonly associated with Fabry's disease using neuroretinal examination (time frame: every 6 months, for up to 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01165697, which also lists 18 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2017.
