A Study of the Safety and Efficacy of Fabrazyme in Patients With Fabry Disease - Full Text View

Purpose

People with Fabry Disease have an alteration in their genetic material (DNA) which causes a deficiency of the alpha-galactosidase A enzyme. Fabrazyme is a drug that helps to breakdown 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 will test the safety and efficacy of Fabrazyme in the treatment of patients with Fabry disease.

Official Title:	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

Further study details as provided by Genzyme:

Primary Outcome Measures:

stabilization of renal function with Fabrazyme by estimating the difference within placebo patients' inverse serum creatinine slope while in AGAL-008-00 versus the inverse serum creatinine slope while in the extension study (AGAL02503) [ Time Frame: throughout study 18 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Serum creatinine, [ Time Frame: throughout study 18 months ] [ Designated as safety issue: No ]
estimated glomerular filtration rate, GFR [as estimated by the Modification of Diet in Renal Disease (MDRD)Study Group equation incorporating: serum creatinine, age, gender, race] [ Time Frame: throughout study 18 months ] [ Designated as safety issue: No ]
plasma GL-3 [ Time Frame: throughout study 18 months ] [ Designated as safety issue: No ]
proteinuria [ Time Frame: throughout study 18 months ] [ Designated as safety issue: No ]
