A Study of the Safety and Efficacy of Fabrazyme in Patients With Fabry Disease

March 13, 2015 updated by: Genzyme, a Sanofi Company

Multi-Center, Open-Label Study of the Safety and Efficacy of Fabrazyme in Patients With Fabry Disease That Previously Participated in the AGAL-008-00 Study

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
