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

Dose-Ranging Study of ST-920, an AAV2/6 Human Alpha Galactosidase A Gene Therapy in Subjects With Fabry Disease (STAAR)

This is the first in human treatment with ST-920, an adeno-associated virus (AAV2/6) vector encoding the complementary deoxyribonucleic acid (cDNA) for human a-Gal A. The purpose of this study is to evaluate the safety and tolerability of ascending doses of ST-920. ST-920 aims to provide stable, long-term production of α-Gal A at therapeutic levels in subjects with Fabry disease. The constant production of α-Gal A in humans should, importantly, enable reduction and potentially clearance of Fabry disease substrates Gb3 and lyso-Gb3. On Day 1, patients will be infused intravenously with a single dose of ST-920 and followed for a period of 52 weeks.

Evaluation of the Effect of a Low-FODMAP Diet on Gastrointestinal Symptoms and Inflammatory Markers in Fabry Patients

The aim of this randomized controlled study is to evaluate the effects of a six-week low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet on gastrointestinal symptoms, inflammatory biomarkers, nutritional status, and quality of life in pediatric and adult patients with Fabry disease. A total of 30 patients with genetically or laboratory-confirmed Fabry disease are planned to be enrolled and randomly assigned to either an intervention group receiving an individualized low-FODMAP diet or a control group continuing their habitual diet. Assessments will be conducted at baseline and after six weeks. Gastrointestinal symptoms, stool characteristics, quality of life, anthropometric measurements, body composition, dietary intake, and biochemical parameters, including inflammatory biomarkers, will be evaluated. The study aims to investigate whether a low-FODMAP diet may provide additional benefits in managing gastrointestinal manifestations and inflammation in patients with Fabry disease.

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.

Therapeutic Implications of CMR Low Native T1 in Non-treated Non-hypertrophic Females With Fabry Disease (FD)

Females with Fabry disease are characterized by variable phenotypes regarding time of onset, severity of symptoms and progression of disease due to the random inactivation of X chromosome leading to a cellular mosaic of mutated and wild genotypes. Left ventricular hypertrophy (LVH) is a relatively late manifestation, appearing typically after the third decade in men and the fourth decade in women. Cardiac involvement progresses throughout life in Fabry females and is the first cause of death but in contrast to males, the loss of myocardial function and the development of fibrosis do not necessarily require myocardial hypertrophy in female with FD. The presence of overt LVH and myocardial fibrosis has been shown to negatively affect treatment outcome, suggesting the importance of early initiation of treatment. Multiparametric cardiac magnetic resonance (CMR) is able to detect sphingolipid infiltration by identifying a pre-LVH phase of cardiac FD defined by a low myocardial native T1, occurring in up to 60% of FD patients, with a concomitant slight elevated LV ejection fraction and electrocardiographic (ECG) changes. Low myocardial T1 values are independently associated with FD progression and are risk factors for clinical worsening. Normal native T1 value is known to be higher in healthy young women than in men but prevalence of low native T1 in Fabry females has not been correctly assessed so far. Treating Fabry females at the appropriate time is still a major issue and remains questionable as therapeutic and financial burden has to be balanced with severity status. However, low native myocardial T1 in CMR is an early marker of cardiac impairment in FD that could justify adapting the therapeutic initiation notably in women. This is of paramount importance as early treatment may provide more benefit before occurrence of irreversible lesions such as LVH and fibrosis.

A Long Term Follow-Up Study of Fabry Disease Subjects Treated With FLT190

Fabry disease is a rare, X-linked inborn error of glycosphingolipid metabolism caused by an abnormal gene encoding the α-galactosidase A (αGLA) enzyme. The αGLA enzyme is ubiquitously expressed throughout the body and is responsible for the breakdown of glycosphingolipids, deficiency of which results in the accumulation of specific glycosphingolipids that are associated with the pathophysiology of the disease. Current treatment for Fabry disease is limited to the symptomatic management of pain, conventional management of complications, and methods to increase the availability of functional αGLA. This clinical study aims to investigate the long-term safety and durability of αGLA in patients who have been dosed with a new gene therapy product (FLT190) in earlier clinical studies.

A Fabry Disease Gene Therapy Study

This is a multinational, open-label study to assess the safety and efficacy of FLT190 in up to 15 adult male participants with classical Fabry disease.

RAre, But Not aLone: a Large Italian Network to Empower the Impervious diaGNostic Pathway of Rare cerEbrovascular Diseases (ALIGNED)

Cerebrovascular diseases (CVDs) are one leading cause of morbidity and mortality worldwide. Despite intensive investigations, more than 30% of strokes remain of undetermined origin. Rare Cerebrovascular Diseases (rCVDs), including heritable (i.e., CADASIL, COL4A1 syndrome, Fabry disease) and acquired conditions (i.e., Sneddon syndrome, Moyamoya arteriopathy) account for a proportion of these strokes. However, rCVDs are often misdiagnosed since clinicians are not able to recognize them. Although rare, the identification of these stroke causes is important to establish appropriate management measures, including genetic counselling, and, if available, therapy. The lack of data on phenotype and clinical course of rCVDs, given the paucity of published series, makes the diagnosis and the development of therapies challenging. Furthermore, the molecular characterization of rCVDs is still lacking, despite progresses achieved in common stroke by applying high throughput approaches as multi-omics. Since the diagnosis and care of rCVDs require adequate expertise and instrumental tools, clinical and research activities are usually reserved to few specialized centers, mostly located in the North of Italy, leading patients to expensive trips for consultations. Therefore, the creation of a clinical and research network aimed at improving the diagnostic pathways of rCVDs is highly needed to improve the number of patients with rCVDs to better define the clinical phenotype and to transfer the knowledge on rCVDs in other centers overall Italy filling the geographical gap affecting Southern Italy.

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.

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

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.
