Bone Response to Enzyme Replacement in Gaucher's Disease
Gaucher's DiseaseThe purpose of this study is to examine how the skeleton responds to repeated doses of enzyme replacement therapy in patients with type I Gaucher's disease who have had their spleens removed. Gaucher disease is a lysosomal storage disease resulting from glycocerebroside accumulation in macrophages due to a genetic deficiency of the enzyme glucocerebrosidase. It may occur in adults but occurs most severely in infants, in whom cerebroside also accumulates in neurons. Patients with Gaucher's disease experience enlargement of the liver and spleen and bone destruction. The condition is passed from generation to generation through autosomal recessive inheritance. Type I is the most common form. It is a chronic non-neuronopathic form, meaning the disease does not affect nerve cells. The symptoms of type I can appear at any age. In this study patients will be divided into three groups. Each group will receive different doses of enzyme replacement (Ceredase). In addition, two of the three groups will also receive doses of a form of vitamin D (calcitriol). Researchers believe the groups receiving vitamin D will have an improved response as compared to those patients only receiving enzyme replacement. Patients in each group who respond to enzyme replacement with increases in bone density will be compared to the other treatment groups.
An Efficacy and Safety Study of AVR-RD-02 Compared to Enzyme Replacement Therapy for Treatment of...
Gaucher DiseaseType 3The purpose of this study is to evaluate the efficacy and safety of autologous hemotopoietic stem cell (HSC) gene therapy, AVR-RD-02, compared to enzyme replacement therapy, for the treatment of Gaucher disease Type 3 in male and female participants aged 2 to 25 years. The study will consist of 2 parts - Core (Part 1) followed by the ERT-crossover (Part 2)
The Effect of Velaglucerase Alfa (Vpriv) on Skeletal Development in Pediatric Gaucher Disease
Gaucher Disease Type 1Gaucher Disease Type 3The purpose of this trial is to study the effect of Velaglucerase Alfa on skeletal bone development of children with Type 1 or Type 3 Gaucher Disease. In addition, the natural history and neurological status of children with Type 3 Gaucher Disease will be studied.
Comparison of BMD Measurement by DEXA to BeamMed Speed-of-Sound Measurement at Forearm in Patients...
Gaucher Disease Type 1The purpose of this study is to compare the accuracy and comparability and secondarily to assess the values achieved by measurement of the forearm BMD by DXA and SOS by BeamMed, relative to standard DXA evaluations at the FN and LS.
A Survey to Assess Participants', Caregivers', and Nurses' Use and Understanding of Educational...
Gaucher DiseaseThe main purpose of this survey is to determine participants', caregivers', and nurses' understanding and use of educational material (EM) on VPRIV home treatment. EM includes an infusion diary and guide and an emergency plan related to VPRIV infusion given at home for Gaucher disease. The survey is conducted in European countries. Data will be collected directly from participants, caregivers, and nurses in form of a questionnaire, electronic or paper.
A Study of the Tolerability, Safety, and Pharmacokinetics of ISU302 in Healthy Volunteers
Gaucher DiseaseThe purpose of this study is to assess the safety, tolerability, and pharmacokinetics of single dosing study with three ascending dose cohorts of ISU302 in healthy subjects.
A Long-Term Follow-up Study of Subjects With Gaucher Disease Who Previously Received AVR-RD-02
Type 1 Gaucher DiseaseThis is a multicenter, multinational long-term follow-up study to assess the long-term safety and durability of effect of AVR-RD-02 treatment in subjects who previously received AVR-RD-02 treatment (single dose administration).
Phase II Study of Glucocerebrosidase in Patients With Gaucher Disease
Gaucher's DiseaseOBJECTIVES: I. Evaluate the efficacy and toxicity of glucocerebrosidase enzyme therapy in patients with Gaucher disease.
A Study of VPRIV in Participants With Gaucher Disease Previously Treated With Other Enzyme Replacement...
Gaucher DiseaseThe main aim of this study is to describe the safety profile of velaglucerase alfa (VPRIV) in participants with Gaucher disease type 1. Participants will be transitioning from other enzyme replacement therapies or substrate reduction therapies to VPRIV. Some participants may have already transitioned to treatment with VPRIV before this study started. In this study, data on VPRIV will be collected from the medical records of participants who already transitioned to VPRIV before this study started. Other participants will join this study when they transition to VPRIV. All participants will be followed to allow for 12 months of observation from time of transition to VPRIV. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.
Chronic Hepatitis C Treatment in Egyptian Children With Gaucher Disease.
Gaucher DiseaseHCVThis prospective open label study is designed to screen all available Gaucher disease patients [either on enzyme replacement therapy (ERT) or not] for hepatitis C virus (HCV) infection. Furthermore to evaluate the safety and effectiveness of combined Sofosbuvir/Ledipasvir regimen given for 12 weeks in chronically infected patients aged 6-18 years.
