Trial summary

This study will determine the rate of sugar metabolism in the brain of patients with Fabry disease, a genetic disease of abnormal lipid metabolism. Compared with healthy people, patients with Fabry disease have increased blood flow to the brain, which may result from abnormal brain metabolic activity. Read more about this study

About this study

Official title: (18)Fluorodeoxyglucose Positron Emission Tomography in Patients With Fabry Disease

This study will determine the rate of sugar metabolism in the brain of patients with Fabry disease, a genetic disease of abnormal lipid metabolism. Compared with healthy people, patients with Fabry disease have increased blood flow to the brain, which may result from abnormal brain metabolic activity. This study will use positron emission tomography (PET) and magnetic resonance imaging (MRI) to compare brain sugar metabolism in eight untreated patients, eight patients who are receiving enzyme replacement therapy, and eight healthy volunteers.

Patients with treated and untreated Fabry disease and normal volunteers may be eligible for this study. Participants will undergo the following two procedures:

  1. PET scan < The patient lies in the PET scanning machine. First, the chest is scanned for a few minutes to determine how much radiation the tissues of the chest absorb. A radioactive sugar called fluorodeoxyglucose (FDG) is then injected through a catheter (thin plastic tube placed in a vein) and the heart is scanned for about 45 minutes to measure the amount of FDG in the blood inside the heart. The head is then scanned for about 20 minutes to measure FDG in the brain. This measurement tells how much sugar the brain uses for energy. The procedure requires insertion of two or three catheters. A special facemask may be molded to the patient's head to help hold the head still during the scanning.
  2. MRI scan < The patient lies on a table surrounded by the scanner (a metal cylinder) for about 60 minutes. A strong magnetic field and radio waves are used to show images of structural and chemical changes in tissues.

This study may provide information that will help explain abnormalities in Fabry disease and the effect of treatment on the brain.

Read the detailed description

We have found that patients with Fabry disease have an increased resting global cerebral blood flow compared with healthy subjects. This augmentation may result from an abnormal metabolic activity in the brain of the patients. The goal of this protocol is to study the cerebral metabolic rate of glucose (rCMRGlu) in eight untreated patients with Fabry disease, eight Fabry patients who are receiving enzyme replacement therapy and compare it with the rCMRGlu eight in healthy volunteers. In order to minimize the need for arterial lines we shall image the left ventricle of the heart to obtain the (18)FDG time-activity curve needed to measure rCMRGlu. The method will be validated in the healthy volunteers.

Questions about this trial

What is this clinical trial studying?

An observational study of Fabry Disease and Healthy, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00005111, which also lists 3 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 4 Mar 2008.
