Overview
Brief Summary
People with Fabry Disease have an alteration in their genetic material (DNA) which causes a deficiency of the alpha-galactosidase A enzyme. Fabrazyme (agalsidase beta) is a drug that helps to break down and removes certain types of fatty substances called "glycolipids". These glycolipids are normally present within the body in most cells. In 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 (globatriaosylceramide or GL-3) levels in these tissues in particular is thought to cause the clinical symptoms that are common to Fabry disease. This study analyzed the safety and efficacy of Fabrazyme in the treatment of patients with Fabry disease that previously participated in the AGAL-008-00 (NCT0074984) study.

Outcomes
Primary Outcomes
Difference in Inverse Serum Creatinine Within Patients' Slopes Between the Placebo AGAL-008-00 (NCT00074984) and Fabrazyme AGAL02503 (NCT00081497) Periods
Time Frame: Placebo period AGAL-008-00 (up to 35 months) through Fabrazyme period AGAL02503 (18 months)
The primary efficacy analysis was the summary of change in slope of inverse serum creatinine for Placebo/Fabrazyme patients in the Intent to Treat (ITT) Population. It compared the placebo period slope with the Fabrazyme period slope.
Secondary Outcomes
- Serum Creatinine at Pre-Fabrazyme and 6, 12, and 18 Months(Pre-Fabrazyme, 6, 12, and 18 months)
- Estimated Glomerular Filtration Rate (eGFR) at Pre-Fabrazyme and 6, 12, and 18 Months(Pre-Fabrazyme, 6, 12, and 18 months)
- Plasma Globotriaosylceramide (GL-3) (Normal Plasma GL-3 Level is ≤ 7.03 µg/mL) at Pre-Fabrazyme and 6, 12, and 18 Months(Pre-Fabrazyme and 6, 12, and 18 months)
- Proteinuria at Pre-Fabrazyme and 6, 12, and 18 Months(Pre-Fabrazyme and 6, 12, and 18 months)
