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 Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Japanese patients with Fabry Disease

Who may be able to join

  • Patients in Japan with the indication of "Fabry Disease" and for whom the usual dosage and administration is 1mg of agalsidase beta (recombinant) per 1 kg body weight each time, administered by intravenous infusion every 2 weeks
  • Because the efficacy evaluation of enzyme replacement therapy with Fabrazyme [agalsidase beta (recombinant form)] will require the comparison of findings before and after the start of enzyme replacement therapy, the efficacy evaluation set will be defined as including patients using Fabrazyme [agalsidase beta (recombinant form)] for the first time in the post-marketing setting and those for whom it is possible to obtain retrospective data for before the start of enzyme replacement therapy.

Who cannot join

  • Patients registered in the post-marketing trials during the post-marketing clinical trial period.

About this study

Official title: Special Survey in Long-Term Use of Fabrazyme

The purpose of this survey is to identify any concerns regarding the following efficacy and safety-related issues in clinical practice with the new drugs "Fabrazyme for intravenous infusion 5mg" and "Fabrazyme for intravenous infusion 35mg" and to confirm the safety of these products in long-term use in the clinical setting.

  1. New adverse drug reactions (ADRs) that cannot be predicted from the Precautions (in particular, clinically significant ADRs)
  2. The incidence of ADRs under the actual conditions of use of the drug
  3. Causal factors that might potentially affect safety
  4. Efficacy evaluation in long-term use

This survey will be conducted in accordance with the approval condition established for Fabrazyme:

"To conduct a special surveillance of Efficacy and Safety in long term treatment and Pediatric with the drug."

Read the detailed description

Medical institutions or physicians will be asked to periodically complete the survey forms for all patients registered. Survey forms include baseline information available, and then data collected every 6 months, as available including: demographic information, concomitant medications/therapy, treatment record, ECG, Echocardiogram, computed tomography scan / magnetic resonance imaging (CT/MRI), Fabry symptoms, labs, functional disorder, blood concentration of GL-3, and anti-agalsidase beta antibody test (IgE testing) to survey whether the productions of antibodies to agalsidase beta is a causal factor of treatment-related reactions.

The survey period shall be approximately 7 years from June 1, 2004 during which survey shall be undertaken as follows:

  • The observation period for each patient shall range from 1 to about 7 years after starting treatment
  • Registration period: June 1, 2004 to March 31, 2010
  • Survey period: June 1, 2004 to March 31, 2011

In institutions for which retrospective surveys are feasible, the survey period will trace back to the date of approval (January 29, 2004), as far as possible.

Questions about this trial

What is this clinical trial studying?

An observational study of Fabry Disease, run by Genzyme, a Sanofi Company at 1 site in Japan.

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 2 inclusion and 1 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 8 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in blood GL-3 level (time frame: 6 months). 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 NCT00233870, 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 8 May 2015.
