  Purpose

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.

Primary Outcome Measures:
  • 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) ] [ Designated as safety issue: No ]
    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 Outcome Measures:
  • Serum Creatinine at Pre-Fabrazyme and 6, 12, and 18 Months [ Time Frame: Pre-Fabrazyme, 6, 12, and 18 months ] [ Designated as safety issue: No ]
    Pre-Fabrazyme=baseline visit of AGAL-008-00 (NCT00074984) for Fabrazyme patients; assessment prior to open-label for placebo patients who transitioned to Fabrazyme in AGAL-008-00 (NCT00074984); assessment prior to first Fabrazyme infusion in AGAL02503 (NCT00081497) for placebo patients who did not transition to Fabrazyme in AGAL-008-00 (NCT00074984).

  • Estimated Glomerular Filtration Rate (eGFR) at Pre-Fabrazyme and 6, 12, and 18 Months [ Time Frame: Pre-Fabrazyme, 6, 12, and 18 months ] [ Designated as safety issue: No ]
    Pre-Fabrazyme=baseline visit of AGAL-00-800 (NCT00074984) for Fabrazyme patients; assessment prior to open-label for placebo patients who transitioned to Fabrazyme in AGAL-008-00 (NCT00074984); assessment prior to first Fabrazyme infusion in AGAL02503 (NCT00081497) for placebo patients who did not transition to Fabrazyme in AGAL-008-00 (NCT00074984).

  • Plasma Globotriaosylceramide (GL-3) (Normal Plasma GL-3 Level is ≤ 7.03 µg/mL) at Pre-Fabrazyme and 6, 12, and 18 Months [ Time Frame: Pre-Fabrazyme and 6, 12, and 18 months ] [ Designated as safety issue: No ]
    Pre-Fabrazyme=baseline visit of AGAL00800 for Fabrazyme patients; assessment prior to open-label for placebo patients who transitioned to Fabrazyme in AGAL00800; assessment prior to first Fabrazyme infusion in AGAL02503 for placebo patients who did not transition to Fabrazyme in AGAL00800.

  • Proteinuria at Pre-Fabrazyme and 6, 12, and 18 Months [ Time Frame: Pre-Fabrazyme and 6, 12, and 18 months ] [ Designated as safety issue: No ]
    Pre-Fabrazyme=baseline visit of AGAL-008-00 (NCT00074984) for Fabrazyme patients; assessment prior to open-label for placebo patients who transitioned to Fabrazyme in AGAL-008-00 (NCT00074984); assessment prior to first Fabrazyme infusion in AGAL02503 (NCT00081497) for placebo patients who did not transition to Fabrazyme in AGAL-008-00 (NCT00074984).
