Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- I. Migalastat-treated patients (Commercial only participants)
- Patients with Fabry disease 18 years or older with amenable GLA variants who have commenced commercial migalastat treatment within 24 months preceding enrollment, who have an eGFR greater than or equal to 30 mL/min/1.73 m2 at the time of enrollment and are still taking migalastat at the time of enrollment, or who are starting migalastat at the time of enrollment, excluding those who participated in a prior migalastat clinical trial
- Patients who show a decline in their Fabry disease symptomatology based on any of the following:
- a decrease in annualized rate of decline eGFRCKD-EPI of ≥ 2 mL/min/1.73 m2 during the 2 years prior to enrollment
- microalbuminuria/macroalbuminuria (≥ 30 mg/24 h or ≥ 20 mg on first morning urine) or urine ACR of ≥ 30 mg/g (via spot urine collection) at any time prior to or at enrollment
- proteinuria (\> 0.5 g/g UPCR) any time prior to or at enrollment
- males with classic Fabry disease phenotype II. Migalastat-treated patients who are not considered to be in renal decline (Commercial migalastat users only) 1\. Patients with Fabry disease with amenable GLA variants who have been on commercial migalastat regardless of the duration of treatment III. Migalastat-treated patients (Prior clinical trial participants)
- Patients with Fabry disease 18 years or older who had commenced treatment with migalastat while in a clinical trial and were exposed to treatment for at least 24 months preceding enrollment, who have an eGFR greater than or equal to 30 mL/min/1.73 m2 at the time of enrollment, and who are still taking migalastat at the time of enrollment, having switched to commercial product IV. Untreated patients
- Patients with Fabry disease 18 years or older with amenable GLA variants, who have never been on treatment for Fabry disease, who have an eGFR greater than or equal to 30 mL/min/1.73 m2 at the time of enrollment, and who meet local treatment guidelines for Fabry disease
- Patients who show a decline in their Fabry disease symptomatology based on any of the following:
- a decrease in annualized rate of decline eGFRCKD-EPI of ≥ 2 mL/min/1.73 m2 during the 2 years prior to enrollment
- microalbuminuria/macroalbuminuria (≥ 30 mg/24 h or ≥ 20 mg on first morning urine) or urine ACR of ≥ 30 mg/g (via spot urine collection) at any time prior to or at enrollment
- proteinuria (\> 0.5 g/g UPCR) any time prior to or at enrollment
- males with classic Fabry disease phenotype V. ERT-treated patients
- Patients with Fabry disease 18 years or older who have commenced ERT within 24 months preceding enrollment, who have an eGFR greater than or equal to 30 mL/min/1.73 m2 at the time of enrollment and are still being treated with ERT at the time of enrollment, and who have amenable GLA variants
- Patients who show a decline in their Fabry disease symptomatology based on any of the following:
- a decrease in eGFRCKD-EPI annualized rate of decline of ≥ 2 mL/min/1.73 m2 during the 2 years prior to enrollment
- microalbuminuria/macroalbuminuria (≥ 30 mg/24 h or ≥ 20 mg on first morning urine) or urine ACR of ≥ 30 mg/g (via spot urine collection) at any time prior to or at enrollment

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
