Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: The FOS registry is open to participants with Fabry disease irrespective of their treatment. Participants may be untreated, currently treated or have been previously treated with Replagal, or any other approved treatment for Fabry disease. There is no predetermined sample size.

Who may be able to join

  • Participants must have a documented diagnosis of Fabry disease
  • This may include a genetic mutation analysis. The collection of the genetic mutation analysis result is optional and dependent on the participant providing their consent for this data to be used in the FOS registry.
  • Participants can be untreated, currently or previously treated with Replagal, or any other approved treatment for Fabry disease.
  • Signed and dated written informed consent from the participant
  • For participants aged less than (<) 18 years (or as per local regulation), parent and/or participant's legally authorized representative (LAR), and assent of the minor, where applicable, is necessary.
  • If a participant is unable to read or if a legally acceptable representative is unable to read, an impartial witness should be present during the informed consent discussion and should sign and personally date the informed consent.
  • Informed consent must be obtained from LARs for cognitively impaired participants when applicable.

Who cannot join

  • 1. Participants currently enrolled in ongoing blinded clinical trials (drugs or devices; includes all blinded trials) will be excluded from the Registry.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An adverse event (AE) is any noxious, pathologic, or unintended change in anatomical, physiologic, or metabolic function as indicated by physical signs, symptoms, or laboratory changes occurring in the registry, whether or not considered product-related. This includes an exacerbation of a pre-existing condition. An AE or ADR that meets one or more of the following criteria/outcomes is classified as SAE whether considered to be related to the pharmaceutical product or not: death, life-threatening, requires inpatient hospitalization or prolongation of existing hospitalizations, a persistent or significant disability or incapacity, a congenital anomaly or birth defect and important medical events.

    Measured: Baseline to year 20

  2. Number of Participants With Infusion-related Reactions (IRRs)

    An infusion-related reaction (IRR) is defined as an AE that has been assessed as at least possibly related to treatment with Replagal and occurs during an infusion or up to 24 hours post Replagal infusion.

    Measured: Baseline to year 20

  3. Renal Function by Estimated Glomerular Filtration Rate (eGFR)

    Renal function will be measured by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) for adults and by Counahan-Barratt for children (<18 years).

    Measured: Baseline to year 20

  4. Left Ventricular Mass Index (LVMI)

    Left ventricular mass index (LVMI) will be assessed from baseline or from birth (age at event) to evaluate the course of Fabry disease in participants who are currently untreated or are being treated with an approved Fabry treatment.

    Measured: Baseline to year 20

  5. Age at Mortality Event (survival)

    Age at mortality event (survival) will be analysed with relevant split by demographic or baseline characteristic using Kaplan-Meier survival estimates with censoring at last visit in Fabry Outcome Survey (FOS)

    Measured: Baseline to year 20

  6. Time to First Morbidity Event

    Time to first morbidity event will be analysed with relevant split by demographic or baseline characteristic using Kaplan-Meier survival estimates with censoring at last visit in FOS.

    Measured: Baseline to year 20

  7. Age at First Morbidity Event

    Age at first morbidity event will be analysed with relevant split by demographic or baseline characteristic using Kaplan-Meier survival estimates with censoring at last visit in FOS.

    Measured: Baseline to year 20

Questions about this trial

What is this clinical trial studying?

An observational study of Fabry Disease, run by Shire 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 7 inclusion and 1 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 16 Nov 2021. 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?

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Baseline to year 20). The study lists 7 primary outcomes in all. 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 NCT03289065, which also lists 5 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 16 Nov 2021.
