Clinical Trial Summary

This Phase 4 study will evaluate the safety and tolerability of Fabrazyme at current approved dose with increases in the infusion rate and reduced infusion volume. This study aims to generate data to provide the guidance on how infusion rate can be safely increased and minimize the burden of the life-long treatment with Fabrazyme.

Description:

The total duration will be up to 6 months
