View clinical trials related to Immunologic Deficiency Syndromes.
Filter by:Severe combined immune deficiency (SCID) may result from inherited deficiency of the enzyme adenosine deaminase (ADA). Children with ADA-deficient SCID often die from infections in infancy, unless treated with either a bone marrow transplant or with ongoing injections of PEG-ADA (Adagen) enzyme replacement therapy. Successful BMT requires the availability of a matched sibling donor for greatest success, and treatment using bone marrow from a less-well matched donor may have a higher rate of complications. PEG-ADA may restore and sustain immunity for many years, but is very expensive and requires injections 1-2 times per week on an ongoing basis. This clinical trial is evaluating the efficacy and safety of an alternative approach, by adding a normal copy of the human ADA gene into stem cells from the bone marrow of patients with ADA-deficient SCID. Eligible patients with ADA-deficient SCID, lacking a matched sibling donor, will be eligible if they meet entry criteria for adequate organ function and absence of active infections and following the informed consent process. Bone marrow will be collected from the back of the pelvis from the patients and processed in the laboratory to isolate the stem cells and add the human ADA gene using a retroviral vector. The patients will receive a moderate dosage of busulfan, a chemotherapy agent that eliminates some of the bone marrow stem cells in the patient, to "make space" for the gene-corrected stem cells to grow once they are given back by IV. Patients will be followed for two years to assess the potentially beneficial effects of the procedure on the function of their immune system and to assess possible side-effects. This gene transfer approach may provide a better and safer alternative for treatment of patients with ADA-deficient SCID.
The purpose of the study is to determine the feasibility of infusing a full 4-week dose of Immune Globulin Intravenous (Human), 10% in a single subcutaneous site and the amount of recombinant human hyaluronidase needed to infuse that dose with no more than mild local adverse drug reactions.
A study in healthy volunteers to determine whether there is a drug interaction between GSK1349572 and the HIV protease inhibitors lopinavir/ritonavir and darunavir/ritonavir
A study to test the safety and effect of twice daily raltegravir in a diverse cohort of patients currently infected with human immunodeficiency virus (HIV), where at least 50% are African American and at least 25% are female, either having received antiretroviral drugs before or not.
These studies are designed to evaluate the relative efficiency of gene transfer into primitive human hematopoietic cells by comparing lentiviral and foamy virus vectors as vehicles for transfer and expression of globin genes. Normal volunteers will serve as research participants. Each will receive a 4 day course of Granulocyte-Colony Stimulating Factor (G-CSF) after which a peripheral blood apheresis will be performed to recover a mononuclear cell population enriched in primitive hematopoietic cells. The stem and progenitor cells will be purified by selection based on expression of the CD34 antigen. The CD34+ population will be cultured in vitro with various cytokines and transduced with vector particles. The efficiency of gene transfer will be evaluated in the transduced CD34+ population, in progenitors contained within that population by culture in semisolid media and in cells capable of establishing human hematopoiesis in immunodeficient mice. The level of transgene expression will be evaluated in mature hematopoietic lineages that develop in vitro or in immunodeficient mice.
This study is a continuation of the study ZLB06_001CR with the objective of assessing efficacy, tolerability, safety of IgPro, as well as long-term health-related quality of life in patients with PID.
Through a prospective observational cohort study enrolling patients newly diagnosed with Human immunodeficiency virus (HIV): Aim 1: Assess attitudes and beliefs about HIV disease and care over time and relate those attitudes and beliefs to success in following the Steps of HIV Care. Aim 2: Validate a simple visual analogue scale for assessing adherence to highly active antiretroviral therapy (HAART) in patients newly starting HAART in routine care. Aim 3: Implement latent growth curve analysis for modeling changes in attitudes and beliefs over time, and for assessing the impact of the components of the Steps of HIV Care model on health outcomes.
The primary objective is to determine the feasibility of attaining acceptable rates of donor cell engraftment (>25% donor chimerism at 180 days) following reduced intensity conditioning (RIC) regimens in pediatric patients < 21 years receiving cord blood transplantation for non-malignant disorders.
The hope of this study is to gather data and information about the tolerability and effectiveness of Lexiva versus Sustiva in patients who have have been generally underrepresented in clinical trials.
