This is a multi-country, observational (non-interventional) study that collects both past and future routine-care data on people with genetically confirmed Fabry disease who are taking or plan to take pegunigalsidase alfa (Elfabrio®). The study uses three cohorts (Cardiac, Naïve, Long-Term) and follows clinical measures and safety over time. Key outcomes include kidney function, a Fabry biomarker, heart imaging and blood markers, and safety events measured up to four years. The study does not assign treatments; participants receive pegunigalsidase alfa as part of their usual care.

What it is studying. The study is measuring real-world safety and effectiveness of pegunigalsidase alfa (Elfabrio®) in people with Fabry disease. It tracks kidney function (estimated glomerular filtration rate, eGFR), levels of the Fabry biomarker lysoGb3, heart structure by cardiac MRI (left ventricular mass index, LVMI) and a blood marker of heart injury (high-sensitivity troponin). It also records safety outcomes including serious adverse events, infusion-related reactions, drug-related adverse events, and the presence of anti-drug antibodies (ADAs) over a four-year timeframe.

What the researchers hope to learn. To gather real-world evidence on the safety and effectiveness of pegunigalsidase alfa (Elfabrio®) in people with Fabry disease. To monitor changes in kidney function, lysoGb3 biomarker levels, heart structure and cardiac injury markers, and to document adverse events and anti-drug antibodies over time.

What this study is about

The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.

A multi-centre, multi-country, observational, non-interventional, retrospective and prospective (hybrid) study among Fabry disease participants treated with pegunigalsidase alfa (Elfabrio®) in routine clinical care.

Interventions being studied

  • Naïve Cohort:
  • Prior exposure to a FD therapy (Replagal®, Fabrazyme®, and Galafold®) at any time point.
  • Severe cardiac fibrosis defined as more than 3 segments that each have >50% fibrosis upon late gadolinium enhancement cMRI on any prior cMRI

This is an observational hybrid study: past medical records may be reviewed and participants will be followed prospectively (outcomes tracked over up to four years). Participants are receiving, or plan to receive, pegunigalsidase alfa by IV infusion as part of routine clinical care and will have clinical tests recorded over time, including kidney function (eGFR), blood biomarkers such as plasma lysoGb3 and troponin, and cardiac MRI measurements when done as standard care (cMRI with gadolinium for those able to have it). The study will collect safety information (serious adverse events and infusion reactions) and participants will complete electronic patient-reported outcome (ePRO) forms.

How the study is structured. An observational cohort study that is non-interventional and hybrid (retrospective and prospective). Participants continue to receive pegunigalsidase alfa under routine clinical care; the study collects past medical data and follows participants forward in time. There are three cohorts (Cardiac, Naïve, Long-Term) defined by clinical history and prior study participation. The protocol plans regular, pre-specified assessments (including annual time points mentioned in the outcomes) and may include cardiac MRI if done as part of standard care.

Questions you could ask

These questions are suggestions for a conversation with the study team or your own clinician, not advice.

  • This is an observational study, so the study itself gives no treatment. What would taking part involve for me, and would it change my usual care?
  • The listed sites are in Slovenia, United Kingdom, United States. Is any of them reachable for me, and does the study help with travel?
  • Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai

contraindications
A reason a particular test or treatment should not be used for a person, for example a metal implant that rules out an MRI scan.
magnetic resonance imaging
A scan that uses magnets and radio waves, not X-rays, to make detailed pictures of the inside of the body. Some implants and metal objects mean a person cannot have one.
Informed consent form
The process of explaining a study, including its risks and what participation involves, so that a person can decide freely whether to take part. Consent is usually documented in writing, and a participant can choose to leave the study later.
Cohort
A group of people who share a characteristic, such as a diagnosis, and are studied together. 'Prospective' means they are followed forward from enrolment; 'retrospective' means existing records are reviewed.
Estimated glomerular filtration rate
A blood-test estimate of how well the kidneys are filtering. Lower numbers mean reduced kidney function; many studies set a minimum value.
enrolment
The number of participants a study plans to include, or has included. 'Estimated' means the planned number; 'actual' means the number who joined.
open label
No masking is used, so the assigned intervention is not deliberately hidden from participants or study staff.
interventional study
A study in which researchers assign participants to one or more interventions, such as a drug, procedure, device, behavioural programme or other approach, to measure their effects.
investigational drug
A treatment that is being tested and has not been approved for this use. It may be approved for a different condition. Being studied does not mean it works or is available outside the study.
Inclusion Criteria
The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
Exclusion Criteria
The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
