Researchers want to see if a lentiviral gene transfer treatment will have the ability to make the patient s immune system more normal, in particular reduce the risk of CGD related infections. The gene transfer takes a person s own stem cells, cultures them to put the normal gene in, then gives the cells back to the person.\n\nObjective:\n\nTo test a gene transfer treatment for X-CGD.\n\nEligibility:\n\nParticipants aged 3-60 with X-CGD\n\nDesign:\n\nParticipants will be screened under protocol 05-I-0123. They will undergo:\n\nMedical history\n\nPhysical exam\n\nHeart tests\n\nImaging tests, as needed\n\nBlood tests\n\nLung function tests, as needed\n\nDental and audiology exams, if needed\n\nQuality of life questionnaire\n\nBone marrow aspiration. A needle will be inserted into the hip bone or breastbone to collect bone marrow.\n\nSome screening tests will be repeated during the study.\n\nParticipants will have an apheresis procedure under protocol 94-I-0073. Stem cells will be collected.\n\nParticipants will get a series of drugs to prepare them for the gene transfer.\n\nParticipants will stay at the NIH Clinical Center for a little over a month. They will get a central line. It is a large intravenous (IV) catheter that is placed into a vein of the neck, chest, or arm. They will get chemotherapy and their corrected stem cells through their IV line.\n\nParticipants will have 12 follow-up outpatient visits in the 2 years after their gene transfer, as well as visits with their local doctor. Then they will enroll in another study for long-term follow-up visits that will last for 13 years.","Study Description:\n\nThis is a Phase I\u002FII, non-Randomized, Single site study, open-label study of a single infusion of autologous CD34+ cells transduced ex vivo with pCCLChimGp91\u002FVSVg lentiviral vector in 10 patients with X-Linked CGD.\n\nObjectives:\n\nPrimary Objective:\n\nTo evaluate the safety, efficacy and stability by biochemical and functional reconstitution in progeny of engrafted cells at 12 months Secondary Objectives:\n\nEndpoints:\n\n* Clinical efficacy and longitudinal evaluation of clinical effect in terms of augmented immunity against bacterial and fungal infection\n* Determine the number of days of antibiotic usage before compared to after gene therapy\n* Transduction efficiency of CD34+ hematopoietic cells from XCGD patients by ex vivo lentivirus-mediated gene transfer\n* Evaluation of engraftment kinetics and stability\n\nPrimary Endpoint:\n\n1.
