Detailed Description:

Fabry disease is an inherited, metabolic disease caused by mutations in the GALA gene. Patients with Fabry disease accumulate a complex glycosphingolipid named globotriaosylceramide (Gb3) in various tissues and organs. All organs are affected in Fabry disease but the majority of the morbidity and mortality are caused by cardiac, renal and neurological dysfunction. Accumulation of Gb3 in the heart causes hypertrophic cardiomyopathy, valvular abnormalities, arrhythmias and infarctions. Replagal has been shown to reduce Gb3 from key tissues and organs, and stabilize renal function in patients with Fabry disease. Evidence suggests that Replagal reduces left ventricular mass (LVM) and improves maximal fractional shortening (MFS)of the heart. Left ventricular hypertrophy is a major cause of morbidity and mortality in patients with Fabry disease.

This is a study of the safety and effectiveness of 3 dosing regimens of Replagal in adult patients with left ventricular hypertrophy due to Fabry disease.

The primary objective of the study will be assessed by comparing 2 dosing regimens of Replagal on reduction of left ventricular mass measured by echocardiography.

The secondary objectives of this study will be assessed by comparing 2 dosing regimens of Replagal on each of the following: exercise tolerance using 2 standard exercise tests; improvement in disease quality of life in heart failure patients; improvement of heart failure symptoms; Standard Safety measurement (i.e.adverse experiences, vital signs, physical exam and laboratory tests).
