Filter by:Gaucher disease, the most prevalent lysosomal storage disorder, is caused by mutations in the human glucocerebrosidase gene (GCD) leading to reduced activity of the lysosomal enzyme glucocerebrosidase and thereby to the accumulation of substrate glucocerebroside (GlcCer) in the cells of the monocyte-macrophage system. This is an extension trial to Study NCT00376168 and NCT00712348.
The purpose of this study is to evaluate the long-term safety of every other week dosing of Gene-Activated® human glucocerebrosidase (GA-GCB, velaglucerase alfa) intravenously in patients with type 1 Gaucher disease.
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 non-inferiority study is to evaluate the efficacy and safety of GA-GCB (velaglucerase alfa) administered every other week in comparison to imiglucerase in treatment naive patients with type 1 Gaucher disease.

The purpose of this study is to evaluate the safety and efficacy of every other week dosing of GA-GCB (velaglucerase alfa) in participants with type 1 Gaucher disease who were previously treated with imiglucerase.
Gaucher disease is a lysosomal storage disorder resulting from a deficiency in the key enzyme b-glucocerebrosidase (GCase). This enzyme is responsible for breaking down a specialized type of fat molecule, known as glucocerebroside, in the lysosome. The enzyme deficiency is caused by genetic mutations which result in the production of misfolded GCase protein. The absent or defective GCase enzyme activity leads to build-up of glucocerebroside inside certain cells. Over time, these Gaucher cells can accumulate and may cause inflammation or damage to specific areas within the body, including the liver, spleen, bone marrow, lung, and the central nervous system. AT2101 is designed to act as a pharmacological chaperone by selectively binding to the misfolded GCase. After binding to the enzyme, it is thought that AT2101 promotes the proper folding, processing, and trafficking of the enzyme from the endoplasmic reticulum to its final destination, the lysosome, the area of the cell where the enzyme does its work. Once it reaches the lysosome, the pharmacological chaperone is displaced and the enzyme can perform its normal function, which is the breakdown of its natural substrate, glucocerebroside. Several in vitro and in vivo preclinical studies have been conducted. In these studies AT2101 increased GCase enzyme level in cells derived from Gaucher disease patients with different genetic mutations, including cells with a genetic mutation associated with the neurologic form of Gaucher disease. In normal mice, oral administration of AT2101 resulted in a dose-dependent increase in GCase level in the liver, spleen, brain, and lung. This study is designed to evaluate the ex vivo response to pharmacological chaperone therapy by testing blood samples from previously treated and untreated patients with Gaucher disease. The study will include patients with non-neuropathic Gaucher disease (type I) and neuropathic Gaucher disease (types II and/or III). Up to 50 patients will be enrolled at the NIH. All subjects will participate in one study visit. Clinical information will be collected retrospectively from medical records. Information collected will include Gaucher disease diagnosis and history, medical history, family history, assessments of clinical severity, and genotype. A blood sample will be collected and various cells will be isolated for laboratory testing and research.
This study evaluated the safety and tolerability of afegostat tartrate in participants with type 1 Gaucher disease who were not receiving enzyme replacement therapy (ERT) or substrate reduction therapy (SRT).
This study was conducted to test the safety and tolerability of afegostat tartrate in participants with type 1 Gaucher disease already receiving enzyme replacement therapy.

The purpose of this study is to evaluate the efficacy of every other week dosing of Gene-Activated® Human Glucocerebrosidase (GA-GCB, velaglucerase alfa) at doses of 45 and 60 U/kg in treatment-naïve patients with type 1 Gaucher disease.

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.

This is the second trial to utilize a recombinant active form of lysosomal enzyme, glucocerebrosidase, (human prGCD) which is expressed and purified in a bioreactor system from transformed carrot plant root cell line.
