Active clinical trials for "Granulomatous Disease, Chronic"

The primary study objective is to collect biospecimen samples (e.g., blood) from participants diagnosed with Chronic Granulomatous Disease (CGD). The biospecimens will be used to create a biorepository that can be used to identify disease associated biomarkers and potential targets with immune and multi-omics profiling. The disease sample collection and analysis will be the foundation for an extensive network of biospecimen access and linked datasets for future translational research.

The research goal of this study is to obtain CD34+ hematopoietic stem cells (HSC) from peripheral blood and/or bone marrow, and Mononuclear Cells (lymphocytes and monocytes), and granulocytes (grans) from peripheral blood that will be used in the laboratory and/or in the clinic to develop new cell therapies for patients with inherited or acquired disorders of immunity or blood cells. Development of novel cellular therapies requires access to HSC, Mononuclear Cells and/or granulocytes as the essential starting materials for the pre-clinical laboratory development of gene therapies and other engineered cell products. HSC or blood cells from healthy adult volunteers serve both as necessary experimental controls and also as surrogates for patient cells for clinical scale-up development. HSC or blood cells from patients serve both as the necessary experimental substrate for novel gene therapy and cellular engineering development for specific disorders and as pre-clinical scale up of cellular therapies. Collection of cells from adult patients collected in the NIH Department of Transfusion Medicine (DTM) under conditions conforming to accepted blood banking clinical practice may also be used directly in or cryopreserved for future use in other NIH protocols that have all required regulatory approvals allowing such use. In summary, the research goal of this protocol is the collection of HSC or blood cells that may be used for both laboratory research and/or for clinical treatment in other approved protocols.

Many genetic diseases of lymphohematopoietic cells (such as sickle cell anemia, thalassemia, Diamond-Blackfan anemia, Combined Immune Deficiency (CID), Wiskott-Aldrich syndrome, chronic granulomatous disease, X-linked lymphoproliferative disease, and metabolic diseases affecting hematopoiesis) are sublethal diseases caused by mutations that adversely affect the development or function of different types of blood cells. Although pathophysiologically diverse, these genetic diseases share a similar clinical course of significant progressive morbidity, overall poor quality of life, and ultimate death from complications of the disease or its palliative treatment. Supportive care for these diseases includes chronic transfusion, iron chelation, and surgery (splenectomy or cholecystectomy) for the hemoglobinopathies; prophylactic antibiotics, intravenous immunoglobulin, and immunomodulator therapies for the immune deficiencies; and enzyme replacement injections and dietary restriction for some of the metabolic diseases. The suboptimal results of such supportive care measures have led to efforts to implement more aggressive therapeutic interventions to cure these lymphohematopoietic diseases. The most logical strategies for cure of these diseases have been either replacement of the patient's own hematopoietic stem cells (HSC) with those derived from a normal donor allogeneic bone marrow transplant (BMT) or hematopoietic stem cell transplant (HSCT), or to genetically modify the patient's own stem cells to replace the defective gene (gene therapy).

X-linked Chronic Granulomatous Disease (CGD) is an inherited disorder caused by an abnormal gene that fails to make the protein known as gp91 phox. This protein is part of a group of proteins that work to create hydrogen peroxide in neutrophils. Neutrophils are a type of white blood cell that helps fight infections. As a result, patients who do not make this gp91 phox frequently develop life-threatening infections. In addition, these neutrophils often act abnormally, resulting in the creation of a granuloma, which is an abnormal collection of cells. These granulomas can then become large enough to block organs, such as the bladder and/or intestines, causing significant problems. Patients are usually treated with antibiotics (often needed for extended periods of time) for the infections caused by CGD, and with corticosteroids for the granulomas. However, these drugs do not cure CGD itself, and can have significant side effects. Thus patients with CGD do not have a normal life expectancy. The only available cure to date for CGD is Bone Marrow Transplantation (BMT), where the blood-making cells from a specially matched brother or sister donor (allogeneic) or a similarly matched unrelated donor are given to the patient after the patient has undergone some kind of chemotherapy or radiation in preparation for receiving the cells. If the cells from the donor engraft (or survive in the marrow), the patient can be cured; however, there is a risk that the cells may not engraft or that they may later get rejected from the body. Also, the cells from the donor can react against the patient, causing a serious disorder called "Graft Versus Host Disease" (GVHD). Although there are a number of methods used to try to reduce and/or prevent graft rejection and/or GVHD, these complications can still occur even with the newer methods now being developed. The risks of such complications are lower when a brother or sister is used as the donor; however, not all patients (even those with siblings) will have an ideally matched donor. Hence, transplantation, especially when using an unrelated donor, is not always a perfect cure. Because the gene responsible for making the gp91 phox is known, it is possible to use gene therapy to try to cure this disease. In gene therapy, some of the blood-making cells are taken from the patient using a technique called apheresis. The normal gene is placed into the cells using special viruses called retroviruses. The cells are then able to produce the normal protein. In this trial, the patient will receive a small dose of chemotherapy called busulfan, lower than what is traditionally used in allogeneic BMT, and the newly corrected cells will then be put back into the patient. Even with the best standard of care, a number of patients with CGD will still die from infection. For those patients who have an unresponsive or progressive infection and do not have a possible sibling donor, their only hope is either a Matched Unrelated Donor (MUD) transplant, which has a high risk of causing death itself, or gene therapy. Hence, we would propose using gene therapy in these patients as this has less risk of causing death, but can still possibly offer a cure. Even if the corrected cells do not remain life long to rid the patients entirely of their disease, as long as they persist for even a few months, they would be able to at least clear the current infection for which the patients are being considered for enrollment in this protocol. Further, they would still be eligible to undergo a matched unrelated donor transplant in the event that gene therapy does not confer any benefit.

Allogeneic blood and marrow transplantation remains the only viable cure for children who suffer from many serious non-malignant hematological diseases. Transplantation, however, carries a high risk of fatal complications. Much of the risk stems from the use of high dose radiation and chemotherapy for conditioning, the treatment administered just prior to transplant that eliminates the patients' marrow and immune system, effectively preventing rejection of the donors' cells. Attempts to make blood and marrow transplantation safer for children with non-malignant diseases by using lower doses of radiation and chemotherapy have largely failed because of a high rate of graft rejection. In many such cases, it is likely that the graft is rejected because the recipient is sensitized to proteins on donor cells, including bone marrow cells, by blood transfusions. The formation of memory immune cells is a hallmark of sensitization, and these memory cells are relatively insensitive to chemotherapy and radiation. Alefacept, a drug used to treat psoriasis, on the other hand, selectively depletes these cells. The investigators are conducting a pilot study to begin to determine whether incorporating alefacept into a low dose conditioning regimen can effectively mitigate sensitization and, thereby, prevent rejection of allogeneic blood and marrow transplants for multiply transfused children with non-malignant hematological diseases.

The purpose of this proposed research is to investigate the efficacy and safety of the therapy with pioglitazone for chronic granulomatous disease (CGD) patients severe infection.

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.

Background: - Chronic Granulomatous Disease (CGD) causes immune system problems. Treatment is usually a bone marrow transplant from a fully matched donor. Researchers want to try using partially matched donors for patients who do not have a fully matched donor available. The researchers will also use the drug cyclophosphamide to try to improve the outcomes when using a partially matched donor. Objective: - To learn the effectiveness of using cyclophosphamide with a transplant from a partially matched donor in treating CGD. Eligibility: - Recipients: age 2-65 with CGD with an ongoing infection that has not been cured by standard treatment and no fully matched donor available in an appropriate timeframe. Design: Recipients will: be admitted to the hospital 2 weeks before transplant. be screened with blood and urine tests, breathing and heart health tests, X-rays, and/or magnetic resonance imaging. They may have a bone marrow aspiration and biopsy. meet with a social worker and dentist. get chemotherapy, radiation, and other medicines. get an intravenous (IV) catheter in their chest. have the transplant. get more medicines and standard supportive care. have blood drawn frequently. have to stay in the Washington, D.C. area for 3 months post-transplant. be followed closely for the first 6 months, and then less frequently for at least 5 years.

This study will determine if the drug infliximab is safe for treating inflammatory bowel disease (IBD) in patients with chronic granulomatous disease (CGD). IBD is an inflammation or irritation of the gut that leads to symptoms such as diarrhea, bloating and stomach cramps. CGD is an inherited disease affecting white blood cells called neutrophils in which patients are susceptible to repeated bacterial and fungal infections. They also have a higher incidence of some autoimmune diseases, such as IBD. Infliximab is approved to treat Crohn's disease, an IBD similar to that seen in patients with CGD. Patients 10 years of age and older with CGD and IBD may be eligible for this study. Candidates are screened with a medical history, physical examination, blood and urine tests, electrocardiogram (EKG), tuberculosis skin test (PPD skin testing), and stool test for the presence of infections. Additional tests may be done, including colonoscopy (procedure using a flexible tube through the rectum to examine the lining of the gut) and imaging studies such as an x-ray, chest CT scan (test using a special x-ray machine), MRI (test using a magnetic field and radio waves), and barium studies (study using a drinkable solution of barium to help enhance the x-ray pictures of the gut). Participants are divided into patients with IBD symptoms (Group 1) and patients without IBD symptoms (Group 2) for the following procedures: Group 1 Patients are evaluated every 6 months with a medical history and physical examination for signs and symptoms of IBD. Patients who are taking moderate to high doses of steroid medications have their medication slowly lowered (tapered) and are evaluated every 3 months for a total of 2 years. Patients in this group who start to develop IBD symptoms are moved to Group 2 for treatment with infliximab (see below). Group 2 Patients in Group 2 receive infliximab infusions at 2-week intervals for three doses. The drug is given over a 2-hour period through a catheter placed in a vein. Patients are evaluated with a medical history, physical exam, and blood tests the day of each dose. One week after the last dose, they have another evaluation, including a colonoscopy. Patients who respond well to infliximab may continue to receive the drug every 2 months for a total of 1 year, with evaluations at every dosing visit. At the end of the first year of receiving infliximab, all patients have follow-up evaluations every 6 months for a total of 2 years. Group 3 Subjects who volunteer to undergo colonoscopy and research biopsies that serve as controls for evaluation of the patient gut samples.
