Quality of Life in Adults With Untreated Fabry Disease in Sweden (QoLUF)

Fabry disease is a rare, inherited condition that can affect multiple organs, including the heart, kidneys, and nervous system. Many people with Fabry disease live for a period of time without receiving disease-specific treatment, for example because treatment criteria have not yet been met. There is limited knowledge about how patients experience this period without treatment. The purpose of this study is to improve understanding of how adults with Fabry disease who are not yet receiving disease-specific treatment experience their quality of life, their daily lives, and their contacts with health care services. This is a national interview study in which participants will take part in one individual digital interview lasting approximately 45-60 minutes. During the interview, participants will be invited to describe their experiences in their own words, including symptoms, how the disease affects everyday life, psychological and emotional well-being, and experiences of follow-up and support from health care providers. Participants will also complete a short questionnaire with basic background information, such as age, education, and living situation. By collecting and analyzing patients' own narratives, the study aims to identify needs, challenges, and support resources during the period without treatment. The results are expected to contribute to increased knowledge and to the development of more person-centered care for individuals living with Fabry disease.

A Study to Learn How Well Lucerastat Works and How Safe it is in Untreated Adult Male Participants With Fabry Disease

The purpose of this clinical trial is to learn how well lucerastat works and how safe it is in untreated adult male participants with Fabry disease. The main question this clinical trial aims to answer is: • Does treatment with lucerastat affects the amount of globotriaosylceramide (Gb3), a fatty substance that builds up in the kidneys, in untreated adult men with Fabry disease? This is an open-label, single-arm trial, which means that participants will know which trial medication they receive and only one trial medication will be given. Trial participants will: * Take lucerastat every day for 18 months * Have kidney biopsies at the end and start of the trial * Visit the clinic 10 times for check-up and tests * Take part in the trial for up to 21 months in total

Long-Term Follow-up of Subjects Who Were Treated With ST-920

Long-term follow-up of subjects who received ST-920 in a previous trial (ST-920-201) and completed at least 52 weeks post-infusion follow-up in their primary protocol. Enrolled subjects will be followed for a total of up to 5 years following ST-920 infusion.

Natural History and Structural Functional Relationships in Fabry Renal Disease Treatment Outcomes(Changes)in Fabry Renal Disease Study

The investigators will perform a study with two major components. The first is a natural history study of untreated Fabry patients. This study component will detail kidney microscopic structural changes in Fabry patients before starting enzyme replacement therapy and will correlate these changes with kidney function, including glomerular filtration rate and urinary albumin excretion rate. The investigators will perform studies on samples obtained at baseline, or before enzyme replacement therapy is initiated. The goal of our study is to find kidney microscopic changes in the biopsies that are associated with kidney disfunction. Our hypotheses for this study are: 1. Much of the natural history of Fabry renal structural changes will occur without detectable renal functional alterations. 2. Structural changes associated with the initial onset of proteinuria and those associated with the subsequent progressive loss of filtration function will differ and will be best described by non-linear models. 3. There will be sufficient precision of Fabry renal structural-functional relationships to support renal structure as an acceptable clinical trial surrogate endpoint for later renal functional deterioration. The second component examines the effects of age and gender at start of enzyme replacement therapy (ERT), as well as dosage levels of ERT on the renal cellular clearance of GL3 from Fabry patients by comparing baseline to follow-up kidney biopsies performed 5, 11, and 60 months later, with all comparisons matched for ERT treatment duration. Our hypotheses for this component of the study are as follows: 1. Enzyme Replacement Therapy(ERT) instituted at younger ages is more effective in reducing podocytes(PC),distal tubular cells(DTC),and arterial smooth muscle cells (ASMC)GL-3 than in older Fabry patients. 2. Earlier institution of ERT will stabilize PC numbers while later ERT institution, especially in proteinuric adults, may not prevent progressive decline in PC numbers and associated glomerular sclerosis, tubulointerstitial injury, and GFR loss. 3. Whereas lower ERT dose may effectively clear GL-3 from endothelial and mesangial cells, it will be less effective in clearing GL-3 from PC and also from DTC and ASMC. 4. Affected cells will be cleared of GL-3 equivalently in females and males.

Fabry Disease Registry & Pregnancy Sub-registry

The Fabry Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Fabry disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The primary objectives of the Registry are: * To enhance the understanding of the variability, progression, and natural history of Fabry disease, including heterozygous females with the disease; * To assist the Fabry medical community with the development of recommendations for monitoring patients and reports on patient outcomes to help optimize patient care; * To characterize and describe the Fabry population as a whole; * To evaluate the long-term safety and effectiveness of Fabrazyme® Fabry Pregnancy Sub-registry: This Sub-registry is a multicenter, international, longitudinal, observational, and voluntary program designed to track pregnancy outcomes for any pregnant woman enrolled in the Fabry Registry, regardless of whether she is receiving disease-specific therapy (such as enzyme replacement therapy with agalsidase beta) and irrespective of the commercial product with which she may be treated. Data from the Sub-registry are also used to fulfill various global regulatory requirements, to support product development/reimbursement, and for other research and non-research-related purposes. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician. If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.

T1 Mapping in Fabry Disease

Fabry disease (OMIM-301500, FD) is a lysosomal storage disease with X-linked inheritance secondary to mutations in the α-galactosidase A gene (GLA), which cause absence or decreased activity of the lysosomal hydrolase a-galactosidase A (a-gal A). The accumulation of globotriaosylceramide (Gb3) leads to multiple organs dysfunction, especially in three key organs: kidney, heart and cerebrovascular system. Progressive nephropathy is one of the main features of Fabry disease and is marked by an insidious development. The investigators are facing different current challenges about treatment initiation in non-classic phenotype patients, optimal dose after treatment initiation, and treatments monitoring in Fabry nephropathy. That is even more important that the enzyme replacement therapy is expensive and a lifelong commitment. Functional magnetic resonance imaging (MRI) is now able to provide T1 mapping sequence. In Fabry disease, T1 mapping is currently used to assess the degree of myocardial involvement. The MRI for assessement of Fabry Cardiomyopathy is now recommended by the 2022 national diagnostic and care protocol (PNDS) in France. However there is no data about T1 mapping values in kidney in Fabry's disease The main Objective is to describe renal performance through multi-parametric MRI in Fabry nephropathy and the primary outcome will be the quantification of renal T1 in Fabry patients.

Fabry Cardiomyopathy: Identification of Early Myocardial Structural and Tissue Abnormalities Using Multiparametric MRI

This study will evaluate whether cardiac MRI T1 and T2 mapping improves our ability to detect early abnormalities in the heart in patients with Fabry disease and identify patients at increase risk of adverse events.

Natural History in Fabry Disease With IVS4+919G>A Mutations

Fabry disease (FD) is a genetic condition where mutations in the GLA gene cause low activity of an important enzyme (alpha-Galactosidase A). This leads to harmful substances building up in the body. A key marker is lyso-Gb3, which can damage organs. FD commonly affects the heart, causing left ventricular hypertrophy (LVH), fibrosis, and worsening heart function over time. In East Asian populations, the exact natural progression of FD is not well understood, even though a specific mutation called IVS4+919G\>A is relatively common due to a "founder effect" seen in places like Taiwan and also in Hong Kong. People with this mutation often develop heart problems later in life, with LVH typically increasing after about age 40. Researchers use advanced heart scans to detect early disease. Cardiac MRI (CMR) native T1 mapping (without contrast) can distinguish normal heart tissue from FD-related changes. CMR measures can reflect different stages of heart damage-starting with accumulation, then inflammation and muscle thickening, and finally fibrosis and impaired function. Some women may not have clear blood test abnormalities yet can still develop ongoing heart damage. Because some MRI findings (like late gadolinium enhancement, LGE) may represent inflammation as well as fibrosis, and because heart damage can progress even before symptoms appear, non-invasive monitoring is important. Imaging methods like strain echocardiography and repeated T1 mapping can track progression, including in patients without obvious early heart thickening. Finally, since most previous studies have included fewer East Asian patients, the study aims to better define the natural history of FD in Chinese patients with the IVS4+919G\>A mutation by following them over time with regular health checks, blood and enzyme testing, kidney and heart function tests, and family/genetic mapping. The goal is to improve guidelines for screening, monitoring, and deciding when to start treatment (ERT).

Anderson-Fabry Disease Fitness Improvement Training: A-FAD-FIT

This study will evaluate whether a 12-week physiotherapy and exercise program can improve physical function and quality of life in patients with Anderson-Fabry disease. Participants will complete assessments before and after the program. The intervention includes regular exercise sessions using body weight, resistance bands, and gradual increases in daily physical activity. The study is intended to determine whether a structured physiotherapy program is feasible and potentially beneficial for people living with Anderson-Fabry disease.

Care Pathway for Patients With Fabry's Disease (Fabry-PATH)

Fabry's disease is an X-linked disorder that manifests differently in men and women, leading to differences in healthcare pathways. In women, the disease is sometimes diagnosed through family screening despite the presence of symptoms (symptoms appear later than in men, and the phenotypic expression of the disease is sometimes more subtle). Conversely, in men, the presence of symptoms combined with abnormalities in medical examinations facilitates diagnosis. There is limited data on the differences in healthcare pathways between men and women, which could nevertheless impact diagnosis by identifying a profile of at-risk patients, and consequently, their management. The goal of this present study is to describe the differences in care pathways between men and women with Fabry's disease, distinguishing entry via symptoms or family screening through a non-interventional study based on a questionnaire sent to patients and on the collection of medical data at the time of diagnosis.

Maternal and Postnatal Outcomes Study (MOS): A Global Observational Registry Assessing the Safety of Elfabrio® in Women With Fabry Disease and Their Infants During Pregnancy and Breastfeeding

The goal of this observational registry is to evaluate the safety and outcomes of pregnancy and lactation in women with Fabry disease who are exposed to pegunigalsidase alfa within 30 days prior to conception and/or during pregnancy and lactation. The main objectives are to: * Assess pregnancy outcomes, including maternal and infant health. * Evaluate the occurrence of congenital malformations and other neonatal outcomes. This is a global, decentralized, single-arm, prospective and retrospective registry planned to enroll participants over a 10-year period. Eligible patients may be enrolled by their physician or may self-enroll, where permitted by local regulations. Data will be collected through a secure web-based platform, allowing patients and physicians to enter information via electronic case report forms (eCRFs). Pregnancy and clinical outcomes will be documented throughout pregnancy and up to 12 months post-birth. Data from self-enrolled patients will be confirmed by their primary care or attending physician. This registry is observational and does not impact clinical care or treatment decisions.
