Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 5 to 18 years
  • Men only
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • The participant and/or participant's parent(s)/legal guardian(s) must provide written informed assent/consent prior to any protocol-related procedures being performed.
  • The participant must had a confirmed diagnosis of Fabry disease as documented by leukocyte α-Galactosidase A (αGAL) activity of <4 nmol/hr/mg leukocyte (preferred assay; resulted from a central laboratory). If the leukocyte αGAL activity assay was difficult to obtain, the participant might be enrolled based on documented plasma αGAL <1.5 nmol/hr/mL, with the agreement of the Medical Monitor (resulted from a central laboratory).
  • The participant must had evidence of globotriaosylceramide (GL-3) accumulation as documented by plasma GL-3 (>7.0 µg/mL) or urinary GL-3 (>0.3 mg GL-3/mmol creatinine) levels (results from a central laboratory).
  • The participant must be male ≥5 and ≤18 years of age.

Who cannot join

  • Participant had albuminuria (first morning void urinary albumin/creatinine ratio >30 mg/g on at least 2 out of 3 consecutive samples, each at least 1 week apart).
  • Participant had a Glomerular Filtration Rate (GFR) by iohexol <90 L/min/1.73m^2. In case of properly documented low protein intake, values as low as 80 mL/min/1.73 m^2 might be acceptable, after consultation with the Medical Monitor.
  • Participant had documented evidence of stroke or transient ischemic attack (TIA), or if a brain magnetic resonance imaging (MRI) had been performed, bright lesions >2 mm on T2- or fluid attenuated inversion recovery (FLAIR)- weighted images within the white matter or the basal ganglia.
  • Participant had severe and recurrent acroparesthesia, judged by the physician as frequent (more than once a week) pain episodes for at least 3 months that influenced daily activities, irrespective of medication.
  • Participant had an end-diastolic left ventricular posterior wall thickness (LVPWTd) and/or an end-diastolic interventricular septum thickness (IVSTd)≥2 standard deviations (SD) compared to normal (based on body surface area [BSA] normal ranges from Kampmann, et al 2000) as read at the study site.
  • Participant had received prior treatment specific to Fabry Disease.
Show all 12Show fewer
  • Participant had participated in a study employing an investigational drug within 30 days of the start of their participation in this study.
  • Participant had any medical condition or extenuating circumstance, which in the opinion of the Study Investigator, could interfere with study compliance.
  • Participant had any medical condition or extenuating circumstance, for example diabetes mellitus, which in the opinion of the Study Investigator, could interfere with the interpretation of study results.
  • Participant was on treatment with angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs).
  • Participant had any contra-indication mentioned in the labeling of Fabrazyme and/or iohexol (Omnipaque).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Skin Globotriaosylceramide (GL-3) Clearance From Superficial Skin Capillary Endothelium

    Skin biopsies were taken at Baseline, Week 52, Week 156 and Week 260 or early withdrawal and analyzed for cellular GL-3 accumulation (inclusions) by light microscopy. Each biopsy was scored for GL-3 accumulation on a severity score-scale of none, mild, moderate, severe (0-1-2-3). Scores are categorized as normal (score = 0) or abnormal (score = 1, 2 or 3). Data was summarized in terms of number of participants with none/trace, mild, moderate and severe biopsy scores.

    Measured: Baseline, Week 52, Week 156 and Week 260

Secondary outcomes (2)
  1. Percent Change From Baseline in GL-3 Clearance From Plasma

    Plasma samples were assayed for GL-3 clearance using a validated tandem mass spectrometry with an upper limit of normal plasma GL-3 level of 7.0 μg/mL. Number of participants analyzed=participants with both baseline and post-baseline GL-3 plasma clearance assessment. Here 'n' signifies number of participants with available data for specified category.

    Measured: Baseline, Week 12, 28, 40, 52, 80, 104, 132, 156, 184, 208, 236 and 260

  2. Percent Change From Baseline in GL-3 Clearance From Urine

    Plasma samples were assayed for total urine GL-3 clearance using a validated tandem mass spectrometry with an upper limit of normal of <0.030 mg/mmoL of creatinine. Number of participants analyzed=participants with both baseline and post-baseline GL-3 urine clearance assessment. Here 'n' signifies number of participants with available data for specified category.

    Measured: Baseline, Week 12, 28, 40, 52, 80, 104, 132, 156, 184, 208, 236 and 260

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Agalsidase beta in people with Fabry Disease, run by Genzyme, a Sanofi Company at 12 sites in 9 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, Canada, Argentina, Brazil, Czechia and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Jun 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Skin Globotriaosylceramide (GL-3) Clearance From Superficial Skin Capillary Endothelium (time frame: Baseline, Week 52, Week 156 and Week 260). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00701415, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2016.
