|Brief Title ICMJE||Replagal Enzyme Replacement Therapy for Adults With Fabry Disease|
|Official Title ICMJE||An Open Label Six-Month Maintenance Clinical Trial of Replagal Enzyme Replacement Therapy in Patients With Fabry Disease Who Have Completed TKT027|
This study will determine the safety and effectiveness of the drug Replagal for treating people with Fabry disease, an inherited metabolic disorder. In this disease, an enzyme called alpha-galactosidase A, which normally breaks down a lipid (fatty substance) known as ceramidetrihexoside, is missing or does not function properly. As a result, the lipid accumulates in the body, causing problems with the kidneys, heart, nerves, and blood vessels. This study will examine whether replacing the missing alpha-galactosidase A with a genetically engineered form of the enzyme called Replagal can reverse the illness.
Patients with Fabry disease who are 18 years of age or older and have completed 10 weeks of Replagal therapy as participants in protocol TKT027 may be eligible for this 6-month study extension.
Participants undergo the following tests and procedures:
Objectives: To evaluate the safety of the current standard Replagal treatment regimen of 0.2 mg/kg given intravenously every two weeks over an additional 6 months in patients who have completed 10 weeks of Replagal therapy in the TKT027 study.
Study Population: Hemizygous males with Fabry disease who are 18 years of age or older who have completed 10 weeks of Replagal therapy in TKT027.
Design: This is an open-label, multi-center study that will assess the safety of 0.2 mg/kg every two weeks of enzyme replacement therapy with Replagal.
