Filter by: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.
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.
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 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.
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.
This is a multicenter, randomized trial to compare the safety and efficacy of two dosing frequencies of Cerezyme® in patients with Gaucher disease who are currently being treated with Cerezyme®. Approximately 90 patients will be randomized in a 2:1 (q4 : q2) ratio to one of two treatment arms at up to 26 study centers worldwide. Patients will continue to receive the same total 4-week dose that they were receiving prior to study enrollment, however, they will be randomized to receive either their total 4-week dose in two infusions, one infusion every 2 weeks or their total 4-week dose in one infusion every 4 weeks. The randomization scheme will ensure a 2:1 balance between the every 4-week versus every 2-week infusion groups, respectively.
The purpose of this study is to learn more about Gaucher disease. The information we collect from medical histories and a blood sample from people with Gaucher disease may help us pinpoint certain things that are different between people who have Gaucher disease and people who do not have Gaucher disease. This information may be useful in the future to help find new treatments for Gaucher disease.
Although miglustat has been approved as a treatment for mild to moderate type 1 Gaucher disease in patients who are unsuitable for enzyme replacement therapy (ERT), more data are required to establish the long term efficacy, safety and tolerability of miglustat in maintaining diseases stability after a switch from ERT.
This study will use positron emission tomography (PET) to compare how people with Gaucher disease or Gaucher disease carriers with parkinsonism, and their family members, use dopamine in their brains in comparison with healthy normal volunteers and people who have Parkinson disease. PET assesses organ function by measuring metabolism. In this study, magnetic resonance imaging (MRI) is used in conjunction with PET to help better interpret and understand the information gleaned from PET. People 21 years of age and older with the following conditions may be eligible for this study: - Gaucher disease and parkinsonism - Parkinsonism and a family history of Gaucher disease - Gaucher disease and a family history of parkinsonism - Gaucher disease carriers who have parkinsonism or a family history of parkinsonism - Unaffected people with a family history of Gaucher disease and parkinsonism - Healthy volunteers Participants undergo the following tests and procedures: - Personal and family medical history - Physical examination - PET scan: The subject lies on a table that slides into the PET scanner until his or her head is positioned properly in the scanner. A catheter is inserted into a vein. An initial scan is done to obtain images before radionuclides are injected. Radioactive water is then injected through the catheter and the subject is asked questions in order to stimulate blood flow in certain areas of the brain to show what parts of the brain are activated. Fluorodopa is then infused through the catheter over 3 minutes. The PET scan can last up to 2 hours. - MRI scan: This test uses a magnetic field and radio waves to obtain images of organs. The subject lies still on a bed in the middle of a circular scanner for about 30 minutes.

This study will use an experimental method of delivering the enzyme glucocerebrosidase directly into the brain of a patient with Gaucher disease to treat disease symptoms. Patients with Gaucher disease have insufficient levels of glucocerebrosidase. As a result, substances normally broken down by this enzyme accumulate in the body, causing damage to the brain and other organs. Symptoms of Gaucher disease outside the brain can be treated by infusing the missing enzyme intravenously (IV, through a vein). However, IV infusions do not help the neurologic symptoms of the disease, because the enzyme cannot get into the brain. This study will use a new technique called convection-enhanced delivery to try to introduce glucocerebrosidase directly into the brain. This single-patient study includes an 8-month-old male with Type 2 Gaucher disease with progressive neurological decline. In preparation for the enzyme infusion, the patient will have a complete physical examination, including a detailed neurological examination, and blood and urine tests. On the day of surgery, the child will be placed under general anesthesia for magnetic resonance imaging (MRI) of the brain. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the child lies on a table that is moved into the scanner (a narrow cylinder), wearing earplugs to protect his hearing from the loud knocking and thumping sounds that occur during the scanning process. He will then be brought to the operating room for the infusion procedure, as follows: An incision will be made in the scalp and a small hole drilled through the skull. Then, a small tube (cannula) will be positioned through the hole into the target area in the brain. Once the tip of the cannula is in place, it will be connected with tubing to a syringe filled with glucocerebrosidase in saline (salt water). The child will then have a second MRI scan to make sure the cannula is placed correctly and to monitor delivery of the glucocerebrosidase to the brain. The child will be monitored closely with MRI scans every 30 to 60 minutes during the infusion to look for fluid in the brain and determine the extent of the enzyme perfusion. The infusion will last no longer than 6 hours and will be stopped when the full dose of enzyme has been delivered. The cannula will be removed and the scalp incision closed. The child will stay in the hospital for observation from 4 to 10 days, with at least 24 hours in the intensive care unit and 3 to 7 days in the pediatric unit. The child will be seen in the clinic two weeks after discharge and then once a month for 3 months to evaluate any possible effects of the surgery. These follow-up visits include a repeat MRI scan and neurological examination. After the first 3 months, visits may be less frequent. If the child continues to have symptoms during the course of follow-up or his neurologic status worsens, additional enzyme infusions will be offered, possibly including treatment of the brainstem. If the child gains no benefit after three infusions have been performed, no additional infusions will be offered. If there appears to be any neurological benefit, additional infusions may be offered.
