People with Fabry disease have an alteration in their genetic material (DNA) which causes a deficiency of the a-galactosidase A enzyme. This enzyme helps to break down and remove certain types of fatty substances called "glycolipids". These glycolipids are normally present within the body in most cells. In people with Fabry disease, glycolipids build up in various tissues such as the liver, kidney, skin, and blood vessels because a-galactosidase A is not present, or is present in small quantities. The build up of glycolipid levels (also referred to as "globotriaosylceramide" or "GL-3") in these tissues is thought to cause the clinical symptoms that are common to Fabry disease. Symptoms commonly appear during childhood with pain in the hands and feet. This study explored the safety, efficacy and pharmacokinetics of Fabrazyme in pediatric patients aged between 7 and 15 years.

Ages Eligible for Study:   7 Years to 15 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion criteria:

  • Patient or legal guardian must provide written informed consent
  • Patients must have a clinical diagnosis of Fabry disease and active Fabry disease (clinical signs and symptoms)
  • Patients must be at least 7 years of age but no older than 15 years of age at time of enrollment
