Key information

About this study

Study participation for each patient will be total of 54 weeks which will include 4 weeks of screening, 48 weeks of treatment period and 2 weeks of post study treatment observation

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participant must be 8 years of age or older, at the time of signing the informed consent
  • Participants naive to agalsidase beta and agalsidase alpha
  • Chinese participants diagnosed with Fabry disease and with documented plasma or leukocyte αGAL activity deficient below laboratory's reference range, and/or documented diagnosis by genotyping
  • Participants must have one or more symptoms and signs consistent with manifestations of Fabry disease (not limited to neuropathic pain, chronic kidney disease, hypertrophic cardiomyopathy, cardiac rhythm disturbances, cerebrovascular involvement, cornea verticillata, angiokeratoma, gastrointestinal symptoms, hypo- or anhydrosis)
  • A female participant is eligible to participate if she is not pregnant or breastfeeding and use an acceptable contraceptive method
  • Participants and/or participant's legal representative capable of giving signed informed consent.

Exclusion criteria

  • The participant has undergone kidney transplantation.
  • The participant has a clinically significant organic disease (with the exception of symptoms relating to Fabry disease) in the opinion of the Investigator, would preclude participation in the trial.
  • Received an investigational drug, or device, other than Fabrazyme, within 30 days of anticipated IMPs administration or 5 half-lives of the previous investigational drug, whichever is longer.
  • The patient has current evidence of kidney failure or renal insufficiency, as defined by eGFR <30 mL/min/1.73 m2.
  • Individuals who have life threatening hypersensitivity (anaphylactic reaction) to the active substance or any of the excipients included.

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

    Time frame: from baseline to Week 6, Week 12, Week 24 and Week 48

  4. The percent changes of plasma GL3

    Time frame: from baseline to Week 6, Week 12, Week 24 and Week 48

  5. The number of participants with abnormal plasma GL3 values per central lab reference range

    Time frame: at Week 6, Week 12, Week 24 and Week 48

  6. The percentage of participants with abnormal plasma GL3 values per central lab reference range

    Time frame: at Week 6, Week 12, Week 24 and Week 48

  7. The change of Fabry disease symptoms

    Time frame: from baseline to Week 24 and Week 48

    The change of Fabry disease symptoms assessment (improved, worsen or same): angiokeratoma, sweating, chronic abdominal pain, level of activity, exercise tolerance and heat tolerance, headache, tinnitus

  8. The absolute change of estimated glomerular filtration rate (eGFR) by chronic kidney disease epidemiology collaboration (CKD-EPI) for adult (≥18 years)

    Time frame: from baseline to Week 12, Week 24, Week 36 and Week 48

  9. The absolute change of estimated glomerular filtration rate (eGFR) by Schwartz for children (8 ≤age <18 years)
