Filter by:The goal of this study is to develop a novel approach to hematopoietic stem cell transplantation for children with Severe Combined Immunodeficiency Disease (SCID) that eliminates the use of toxic chemotherapy conditioning and maximizes the likelihood of T and B cell immune reconstitution. Rather than classic chemotherapeutic agents, the investigators will utilize a targeted stem cell mobilizer, plerixafor, in combination with alemtuzumab, a monoclonal antibody. Correlative scientific questions will include: 1) efficacy and characteristics of host stem cell mobilization; and 2) alemtuzumab pharmacokinetics in very young children.
Background: - Chronic granulomatous disease (CGD) is an immunodeficiency disease in which white blood cells are unable to kill certain bacteria and fungi. People with CGD are more likely to develop recurrent life-threatening infections. Certain changes or mutations in genes contribute to the severity of CGD, and also appear to affect the success of treatment with interferon-gamma, a substance that is used to improve the immune system s ability to fight infection. Researchers are interested in studying changes in the immune system caused by interferon-gamma treatment of CGD in individuals with different mutations that cause CGD. Objectives: - To compare changes in the immune system caused by interferon-gamma treatment for CGD in individuals with different mutations that cause CGD. Eligibility: - Individuals of any age who have been diagnosed with CGD and have specific types of mutations that cause CGD (to be determined after testing). Design: - Participants will be screened with a medical history, physical examination, and blood and urine tests. Participants must weigh more than 11 kilograms (~24 pounds) to participate in the study. - Participants will receive injections of interferon-gamma once weekly for 4 weeks, twice weekly for 4 weeks, and then three times weekly for 4 weeks (a total of 24 injections). - Blood will be drawn periodically during treatment and for 8 weeks after the treatment, for a total of 21 weeks on the study. Participants will regularly provide information on their symptoms and responses to treatment to the study researchers.
Unrelated matched donor (cord blood, bone marrow or peripheral blood) allogeneic stem cell transplantation (UDAlloSCT) with either myeloablative or reduced intensity conditioning will be well tolerated and result in a high degree of engraftment in patients with selected malignant and non malignant disorders.
The purpose of this study is to determine the ability of a donor lymphocyte infusion (DLI) given with methotrexate to hasten immune recovery without causing severe graft-versus-host disease (GVHD) in recipients who have had a T-cell depleted transplant.
This is a study to assess the response of lopinavir/ritonavir plus maraviroc (with no nucleoside medications) in HIV patients failing their initial antiviral therapy.
The primary purpose is to determine the ability of CD34+ selection and T cell depletion using the CliniMACS® device to prevent severe acute graft-versus-host disease (GVHD) in patients receiving a stem cell transplant from an alternative (unrelated and mismatched related) donor. The secondary objectives include evaluation of engraftment, immune recovery, and post-transplant infections. Patients requiring stem cell transplants for either malignant (cancerous) or non-malignant disease will be included in the study. The recipients will be grouped into one of two groups based on whether the donor is mismatched related (Cohort A) or unrelated (Cohort B). The patient will receive a conditioning regimen including chemotherapy drugs and/or total body irradiation based on the disease for which the transplant is performed.
Octagam is a human normal immunoglobulin (IGIV) solution for intravenous administration. Octagam 5% is currently registered in more than 60 countries. This study will evaluate the efficacy, safety and the kinetics of Octagam 10% for replacement therapy in primary immunodeficiency diseases.
The purpose of this study is to determine the safety and toxicity and feasibility of double umbilical cord blood transplantation (DUCBT) in patients with selected malignant and non-malignant, and to quantify the percentage and donor sources of mixed donor chimerism following DUCBT in patients with selected malignant and non-malignant disorders.
This is an investigator-initiated, two-year, randomized, controlled, single-center, open-label, pilot study comparing 3-drug highly active antiretroviral therapy (HAART) to 3-drug HAART plus raltegravir for persons with acute and early HIV-1 infection. The study will test the hypothesis that use of the integrase inhibitor raltegravir (400 mg BID orally) to inhibit the integration step of the HIV-1 life cycle in conjunction with HAART in subjects with recently acquired HIV-1 infection will decrease the number of HIV-1 infected CD4+ T-cells to a greater extent than a 3-drug HAART regimen.
The ideal anti-HIV medications for patients with advanced HIV disease is unknown. There is evidence that anti-HIV regimens that contain protease inhibitors can enhance immune function better than regimens that do not contain protease inhibitors. This is a study that will determine the difference in immune enhancement capabilities between an anti-HIV regimen that contains the protease inhibitor - lopinavir-ritonavir, and a regimen that contains efavirenz. Both medications are recommended as first line treatments for HIV-infected patients. This study will recruit HIV-positive patients that need to start anti-HIV treatment because their CD4+ T-cells are below 200. The usual threshold for starting treatment is a CD4+ T-cell less than 350. Subjects will be randomized to treatment with either an anti-HIV regimen that contains lopinavir-ritonavir or a regimen that contains efavirenz. The study will determine the difference in immune reconstitution over 24 weeks of treatment with study medications. Among the immune parameters that will be measured is the ability of each subject to respond to vaccination with the tetanus-diphtheria vaccine and the 23-valent pneumococcal vaccine. Both vaccines are also recommended for HIV-positive patients but HIV-positive patients tend to have a lower response rate to these vaccines.
