Study Description

Brief Summary:

The purpose of this study is to collect data that will increase understanding of Fabry disease history and progression, in treated and untreated patients with Fabry disease. The data from FOS may provide guidance to healthcare professionals about disease treatment options.

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline to year 20 ]
   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.
2. Number of Participants With Infusion-related Reactions (IRRs) [ Time Frame: Baseline to year 20 ]
   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.
3. Renal Function by Estimated Glomerular Filtration Rate (eGFR) [ Time Frame: Baseline to year 20 ]
   Renal function will be measured by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) for adults and by Counahan-Barratt for children (<18 years).
4. Left Ventricular Mass Index (LVMI) [ Time Frame: Baseline to year 20 ]
   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.
5. Age at Mortality Event (survival) [ Time Frame: Baseline to year 20 ]
   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)
6. Time to First Morbidity Event [ Time Frame: Baseline to year 20 ]
   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.
7. Age at First Morbidity Event [ Time Frame: Baseline to year 20 ]
   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.

Eligibility Criteria

• Ages Eligible for Study: Child, Adult, Older Adult
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No
• Sampling Method: Non-Probability Sample

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.

Criteria

Inclusion Criteria:

1. 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.

2. 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.

Exclusion Criteria:

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