Trial summary

The purpose of this study is to compile a registry of patients with Fabry disease, an inherited metabolic disorder. In this disease, an enzyme called a-galactosidase A, which normally breaks down a lipid (fatty substance) called globotriaosylceramide (Gb3), is missing or does not function properly.

About this study

Official title: Registry of Fabry Disease: A Multicenter, Longitudinal Observational Study

The purpose of this study is to compile a registry of patients with Fabry disease, an inherited metabolic disorder. In this disease, an enzyme called a-galactosidase A, which normally breaks down a lipid (fatty substance) called globotriaosylceramide (Gb3), is missing or does not function properly. As a result, Gb3 accumulates, causing problems with the kidneys, heart, nerves, and blood vessels. It is not known exactly how lipid accumulation causes these problems, but in another lipid storage disease called Gaucher disease the illness can be reversed if the accumulated lipid is removed by repeated intravenous (into a vein) infusions of the deficient enzyme.

The Fabry disease registry is a voluntary and anonymous list of patients that includes information about their health and allows doctors to follow changes in their symptoms and test results over time. It also allows doctors to compare symptoms between patients who are receiving certain therapies with those who are not receiving therapy. The goals of the registry are to:

Read more
  • Better understand the natural history of Fabry disease, including disease variations within and between affected families;
  • Provide a basis for developing guidelines for disease management;
  • Evaluate how treatment affects the course of disease;
  • Provide high-quality data and analyses that will help to continuously develop better treatments.

Patients of all ages with biochemical or genetic evidence of Fabry disease (i.e., individuals who have a deficiency of the enzyme a-galactosidase A or a mutation in the gene that encodes this enzyme, or both) are eligible for this study. This worldwide study will include 100 patients participating in Fabry disease studies at the NIH. These patients will come to the NIH Clinical Center only as required for participation their Fabry disease study. No additional procedures will be required for the current registry study.

NIH patients will take part in the registry study for their lifetime, or as long as they are being followed at the NIH for their Fabry disease. At their regularly scheduled NIH clinic visits, participants will have routine medical procedures and examinations deemed necessary by the doctor. The results of blood and urine tests taken at these visits will be entered into the registry database. Blood tests will include information on genotype (determination of which gene mutation is responsible for the disease), a-galactosidase A levels, Gb3 levels, and creatinine. Urine tests results will include creatinine clearance (a measure of kidney function) and protein evaluation.

PROTOCOL TITLE: Registry of Fabry Disease: A Multicenter, Longitudinal Observational Study

PROTOCOL IDENTIFIER: FOS (Fabry Outcome Survey)

PHASE OF DEVELOPMENT: Post Marketing Outcome Survey (Outcome Survey)

SURVEY OBJECTIVES/ENDPOINTS:

The primary objectives of this outcome survey are to:

  • enhance the understanding of the natural history of Fabry disease, including the intra- and inter-familial variations
  • provide a basis for the development of management guidelines for Fabry disease
  • evaluate the impact of therapeutic intervention on the clinical course of Fabry disease
  • generate data and analyses to enable the continuous improvement of Fabry disease treatment
  • collect long term safety and efficacy data on patients treated with Replagal enzyme replacement therapy

INCLUSION CRITERIA:

This registry/outcome survey is open for all patients of all ages, male and female, with a confirmed diagnosis of Fabry disease.

EXCLUSION CRITERIA:

  • Patients who are unwilling to give informed consent.
  • Patients who are receiving enzyme replacement therapy other than Replagal for Fabry Disease
  • Patients currently enrolled in an ongoing blinded clinical trial in which the product is considered investigational.

NUMBER OF SUBJECTS PLANNED AND DURATION OF SUBJECT PARTICIPATION:

There is no predetermined number of patients that must be enrolled into the outcome survey. Patients who have been diagnosed (biochemically or genetically) with Fabry disease that consent to participate will be followed for an undetermined amount of time (i.e., until the sponsor closes the outcome survey or the patient withdraws consent).

TREATMENTS ADMINISTERED AND TREATMENT SCHEDULE:

Patients consenting to participate in the outcome survey will either be untreated or treated with Replagal ERT. It is recommended that patients be followed at increments determined to be necessary by the treating physician. It is also recommended that data on all patients be entered into the outcome survey on a bi-annual basis (every six (6) months).

Patients will not be supplied with Replagal at no charge as a result of participating in the Fabry Outcome Survey (FOS). Patients will receive Replagal through their participation in ongoing open label clinical trials or compassionate programs. Additionally, patients may receive commercially available product.

SURVEY ASSESSMENT SCHEDULE:

It is recommended that patients be followed at clinically relevant intervals determined by their treating physician. Data collected is to be entered into the FOS database as soon as possible after physician assessments.

SURVEY METHODOLOGY:

Observational data will be recorded in the FOS database based on routine clinical evaluations performed by the treating physician.

STATISTICAL METHODOLOGY:

The statistical analysis of FOS data will be performed by a bio-statistician designated by Shire HGT and in accordance with documented company guidelines and standard operating procedures.

Questions about this trial

What is this clinical trial studying?

An observational study of Fabry Disease, run by National Institute of Neurological Disorders and Stroke (NINDS) at 2 sites 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 1 inclusion and 3 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 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 NCT00055016, which also lists 1 linked publication.

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 2 Jul 2017.
