Criteria

Inclusion Criteria:

provided written informed consent prior to any study-related procedures being performed.
be ≥16 years old.

Time to Clinically Significant Progression of Cardiac Disease, Cerebrovascular Disease, and/or Death Among Fabry Patients With Severe Kidney Disease

The trial was terminated early due to inadequate study design. During the study period of 7 months, only 1 patient had a clinical event, a stroke, in the Fabrazyme 1 mg/kg treatment arm. The time to event was determined from first dose of Fabrazyme to the date of event.

Plasma Globotriaosylceramide (GL-3)

This outcome measure evaluated the mean plasma GL-3 values for all patients to see if it decreased while on Fabrazyme. Normal plasma GL-3 level is defined as ≤ 7.03 µg/mL.
