Active clinical trials for "Gaucher Disease"

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 the first 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.

Absorption of therapeutic proteins taken orally has remained the major hurdle for treatment in humans. The proteins are generally degraded by enzymes in the stomach and intestine and the intestine lining that prevents absorption into the circulation. Administration of PRX-112, a plant recombinant human glucocerebrosidase (prGCD) using plant cells as carrier vehicle, may help overcome many of these hurdles. The plant cell wall protects the protein from degradation in its transport through the upper GI and allows release in the lower intestine. Studies in animals have shown that prGCD delivered in this way can be found in the blood stream in an active form.

This is an open-label, dose escalation study to evaluate the safety of oral PRX-112 and pharmacokinetics of GCD in subjects with Gaucher disease naive to enzyme replacement therapy. The dose levels of PRX-112 are 50 units, 100 units, 200 units and 400 units GCD. Subjects will receive once daily oral administrations of PRX-112 for 5 consecutive days at each dose level with a 2-day washout period between doses.

Evaluation of the safety in the combination usage of Cerdelga and Cerezyme in type III Gaucher disease patients and the efficacy on soft tissue diseases.

The primary objective of this study was to evaluate the efficacy and safety of once daily (QD) versus twice daily (BID) dosing of eliglustat tartrate (Genz-112638) in participants with Gaucher disease type 1 who had demonstrated clinical stability on BID dosing of eliglustat tartrate (Genz-112638). The secondary objective was to evaluate the pharmacokinetics (PK) of Genz-99067 when eliglustat tartrate (Genz-112638) was administered QD and BID in participants with Gaucher disease type 1 who had demonstrated clinical stability on BID dosing of eliglustat tartrate (Genz-112638).

Gaucher disease is a rare lysosomal storage disorder caused by the deficiency of the enzyme glucocerebrosidase (GCB). Due to this 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 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.

This is a multicenter, open-label, prospective study of the efficacy of Cerezyme in treating patients with skeletal manifestations secondary to Type I Gaucher disease. The study objective is to evaluate and quantify skeletal responses as compared to baseline in Type I gaucher disease patients receiving Cerezyme therapy for 48 months. Additional objectives were to assess the usefulness of various skeletal parameters, such as bone pain, bone crises, bone mineral density, and serum and urine bone markers, as indicative of treatment response and may be useful in dose management.

Gaucher disease is a lysosomal storage disease resulting from glucocerebroside accumulation in macrophages due to a genetic deficiency of the enzyme glucocerebrosidase. It may occur in patients of all ages. The condition is marked by enlargement of the liver and spleen (hepatosplenomegaly), low blood and platelet counts, and bone abnormalities. The condition is passed from generation to generation on via autosomal recessive inheritance. There are actually three types of Gaucher disease. Type I is the most common form. It is a chronic non-neuronopathic form, meaning the disease does not affect the nervous system. The symptoms of type I can appear at any age. Type 2 Gaucher disease presents prenatally or in infancy and usually results in death for the patient. Type 2 is an acute neuronopathic form and can affect the brain stem. It is the most severe form of the disease. Type 3 Gaucher disease is also neuronopathic, however it is subacute in nature. This means the course of the illness lies somewhere between long-term (chronic) and short-term (acute). Currently there is not a cure for Gaucher disease. Treatment for the disease has traditionally been supportive. In some severely affected patients, bone-marrow transplants have corrected the enzyme deficiency, but it is considered a high-risk procedure and recovery can be very slow. Enzyme replacement therapy is another therapy option and has been approved by the Food and Drug Administration (FDA) for use in type 1 patients. PEG-glucocerbrosidase is a drug designed to clear out the accumulation of lipid (glucocerebroside) from the blood stream. The drug is actually an enzyme attached to large molecules called polyethylene glycol (PEG). The large molecules of PEG allow the enzyme to remain in the blood stream for long periods of time. By modifying glucocerebrosidase with PEG, it is believed that smaller doses will be required, meaning a reduction in cost for the patient and more convenient administration of the drug. The purpose of this study is to evaluate the effects and safety of enzyme replacement therapy using PEG- glucocerebrosidase for the treatment of Gaucher disease.

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.

Primary Objective: To study the effect of mild and moderate hepatic impairment on the pharmacokinetics (PK) of eliglustat. Secondary Objective: To assess the tolerability of eliglustat tartrate given as a single dose in subjects with mild and moderate hepatic impairment in comparison with matched subjects with normal hepatic function.
