It may occur in patients of all ages. The most severe form, Type 2 Gaucher's Disease occurs in infants who die in the first years of life (with rapidly progressive neurologic deterioration). The condition is passed from generation to generation through autosomal recessive inheritance.\n\nFabry's disease isa genetic disorder (X-linked recessive) due to the absence of the enzyme a-galactosidase A. The disease is characterized by abnormal collections of glycolipids in cells (histiocytes) within blood vessel walls, tumors on the thighs, buttocks, and genitalia(2) decreased sweating, tingling sensations in the extremities, and cataracts. Patients with Fabry's disease die from complications of the kidney, heart, or brain.\n\nBoth conditions are caused by the absence of specific enzymes (3). Patients with these conditions are missing (3) or have defective genes needed for the normal production of these enzymes. Studies on the blood-forming cells in bone marrow have lead to gene therapies using retroviruses as vehicles to carry and insert working genes into abnormal or diseased cells.\n\nThis study is designed to measure the safety and effectiveness of transferring working copies of genes responsible for making missing enzymes into the cells of patients with Gaucher's or Fabry disease.", "detailedDescription"=>"This protocol was developed in order to obtain bone marrow stem cells for ex vivo transduction with retroviruses containing the human glucocerebrosidase gene. We continue to enter a small number of patients to this protocol each year. Studies with the bone marrow hematopoietic progenitor cells have enabled us to identify the most effective retroviral construct currently available in order to carry out gene therapy trials in patients with Gaucher's disease. The data revealed that a comparatively simple retroviral construct containing human glucocerebrosidase cDNA driven by the MoLV promoter is highly effective. We have obtained approval and initiated a Phase I safety and gene marking investigation in patients with Type I Gaucher's Disease."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD", "ADULT", "OLDER_ADULT"], "healthyVolunteers"=>true, "eligibilityCriteria"=>"Normal and patient volunteers.\n\nIndividuals with platelet counts less than 40,000/ul, PT greater than 15 seconds, or PTT greater than 40 seconds will not undergo bone marrow aspiration.\n\nIndividuals with hematologic disorders other than Gaucher Disease, Fabry Disease, or mild iron deficiency will not undergo bone marrow aspiration.\n\nHIV positive individuals will be excluded from participating."}, "identificationModule"=>{"nctId"=>"NCT00001234", "briefTitle"=>"Gene Therapy for Gaucher's and Fabry Disease Using Viruses and Blood-Forming Cells", "organization"=>{"class"=>"NIH", "fullName"=>"National Institutes of Health Clinical Center (CC)"}, "officialTitle"=>"Retroviral-Mediated Transfer and Expression of Glucocerebrosidase and Ceramidtrihexosidase (a-Galactosidase A) cDNA's in Human Hematopoietic Progenitor Cells", "orgStudyIdInfo"=>{"id"=>"880019"}, "secondaryIdInfos"=>[{"id"=>"88-N-0019"}]}, "armsInterventionsModule"=>{"interventions"=>[{"name"=>"human glucocerebrosidase cDNA", "type"=>"GENETIC"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"20892", "city"=>"Bethesda", "state"=>"Maryland", "country"=>"United States", "facility"=>"National Institute of Neurological Disorders and Stroke (NINDS)", "geoPoint"=>{"lat"=>38.98067, "lon"=>-77.10026}}]}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"National Institute of Neurological Disorders and Stroke (NINDS)", "class"=>"NIH"}}}}
