NCT00391625 ↗	Open-Label Extension Study Evaluating Long Term Safety in Patients With Type 1 Gaucher Disease Receiving DRX008A (ERT)	Completed	Shire	Phase 1/Phase 2	2004-09-13	Gaucher disease is a rare lysosomal storage disorder caused by the deficiency of the enzyme glucocerebrosidase (GCB). Due to the deficiency of functional GCB, glucocerebroside accumulates within macrophages leading to cellular engorgement, organomegaly, and organ system dysfunction. The purpose of this study is to evaluate the long term safety of enzyme replacement therapy with DRX008A (VPRIV®, GA-GCB; velaglucerase alfa) in patients with type 1 Gaucher disease.
NCT00954460 ↗	Treatment Protocol of Velaglucerase Alfa for Patients With Type 1 Gaucher Disease	Approved for marketing	Shire		1969-12-31	Gaucher disease is a rare lysosomal storage disorder caused by the deficiency of the enzyme glucocerebrosidase (GCB). Due to the deficiency of functional GCB, glucocerebroside accumulates within macrophages leading to cellular engorgement, organomegaly, and organ system dysfunction. The purpose of this treatment protocol is to observe the safety of velaglucerase alfa in patients with type 1 Gaucher disease who are either treatment naive (newly diagnosed) or who are currently being treated with the Enzyme Replacement Therapy (ERT) imiglucerase.
NCT01842841 ↗	Multicenter Extension Study of Velaglucerase Alfa in Japanese Patients With Gaucher Disease	Completed	Quintiles, Inc.	Phase 3	2013-03-13	Gaucher disease is an inherited deficiency of the lysosomal enzyme glucocerebrosidase (GCB) that leads to progressive accumulation of glucocerebroside within macrophages and subsequent tissue and organ damage; typically of the liver, spleen, bone marrow, and brain. Type 1 Gaucher disease affects an estimated 30,000 persons worldwide and is the most common. Type 1 Gaucher disease does not involve the central nervous system. Patients with Type 2 Gaucher disease present with acute neurological deterioration, which leads to early death. Those with Type 3 disease typically display a more sub-acute neurological course, with later onset and slower progression. The primary objective of this study is to evaluate the long-term safety of every other week (EOW) dosing of velaglucerase alfa in Japanese patients with Gaucher disease who completed study HGT-GCB-087 and elected to continue treatment with velaglucerase alfa. Velaglucerase alfa has been developed and approved as an enzyme replacement therapy for Type 1 Gaucher disease.
