NCT05189925
Background: CGD is caused by a gene mutation. For people with CGD, their cells cannot kill germs well, so they can get frequent or life-threatening infections. Researchers want to see if a new procedure can help a person s cells kill germs for a short time. It uses messenger RNA (mRNA) to deliver correct instructions for the gene mutation to the cells. Objective: To test a procedure in which mRNA is added to a person s blood cells. Eligibility: Males aged 18-75 with CGD with a mutation in the gene that makes the protein gp91phox. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Swab to test for strep throat Some screening tests will be repeated during the study. Participants will be admitted to the NIH Clinical Center hospital for at least 7 days. They will have apheresis. For this, a medicine is injected under their skin to prepare their white blood cells for collection. An IV line is placed into an arm vein. Blood goes through the IV line into a machine that divides whole blood into red blood cells, plasma, and white blood cells. The white blood cells are removed, and the rest of the blood is returned to the participant through an IV line in their other arm. The next day, they will get their mRNA-corrected cells via IV. They will be monitored for 3 more days. After discharge, participants will keep a symptom diary. They will be contacted weekly for one month, and then once a month. They will have a follow-up visit 3 months after the infusion.
NCT06665399
The goal of this observational study is to investigate the disease progression rate and timing in patients with mild Non-Lactational Granulomatous Lobular / Periductal Mastitis (NL-GLM/PDM) during follow-up with observation alone strategy. The main questions it aims to answer are: What is the rate of disease progression in mild NL-GLM/PDM patients under observation, and what clinical and pathological factors are associated with this progression? Participants with diagnosis of mild NL-GLM/PDM will be monitored over a specified period, with data collected on their clinical outcomes and relevant factors influencing disease progression.
NCT01676805
Background: \- Lab studies help researchers better understand cancer biology. This information may lead to new methods for diagnosing or treating cancer. To develop these studies, researchers want to collect samples from people with cancer or precancer conditions of the lymph system. These conditions include multiple myeloma, different types of lymphoma, and adult leukemia/lymphoma. The samples collected will include blood, urine, bone marrow, and tumor and skin tissue. Objectives: \- To collect tissue samples to study different types of lymph cancer. Eligibility: \- Individuals at least 18 years of age who have a lymphoid cancer or precancer condition. Design: * Participants will be screened with a physical exam and medical history. * Different samples will be collected for study. Blood samples will be collected at the initial testing. More blood samples will be collected at different treatment points. Other liquid samples include urine, bone marrow, and any abnormal fluid. Tumor tissue and skin tissue biopsies will also be collected for study. * Treatment will not be provided as part of this study.
NCT03155620
This phase II Pediatric MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.
NCT05915208
The purpose of the study is to describe the burden of chronic health conditions, psychological dysfunction, chronic pain, healthcare utilization, worse health-related quality of life, overall mortality, and cause-specific mortality among individuals with histiocytic disorders
NCT00001405
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.
NCT07595900
Non-Lactational Granulomatous Lobular Mastitis (NL-GLM) is an inflammatory disease of unknown etiology, characterized clinically by local breast masses, accompanied by redness and swelling of the overlying skin, sinus tract formation, and other symptoms. Currently, there is no universally accepted standard treatment for this condition; previous expert consensus or practice guidelines have mostly recommended systemic glucocorticoid therapy as the primary treatment approach. Our team's preliminary research has confirmed that local glucocorticoid injection achieves efficacy equivalent to systemic administration but with better safety, making it a first-line treatment option for NL-GLM. However, in our preliminary studies and literature reports, we found that some patients still exhibit glucocorticoid dependence or resistance (i.e., refractory NL-GLM) after receiving either local or systemic glucocorticoid therapy. The lack of high-quality evidence to support subsequent-line treatments has become a major bottleneck in clinical management. Additionally, some patients cannot tolerate glucocorticoid therapy due to its adverse effects. Research has shown that the IL-6 inflammatory pathway is significantly activated in the lesion tissues and peripheral blood of NL-GLM patients, and the IL-6 inhibitor tocilizumab has demonstrated efficacy in various autoimmune diseases. Based on this, this study intends to conduct a dual-center, single-arm clinical trial to systematically evaluate the efficacy and safety of tocilizumab in the treatment of refractory NL-GLM. The aim is to fill the treatment gap, provide high-level evidence for clinical practice, and ultimately improve patient outcomes.
NCT04157348
This is a randomized, double blind, active-controlled, parallel group, multicenter 52-week Phase 3 study to compare the efficacy and safety of benralizumab 30 mg versus mepolizumab 300 mg administered by subcutaneous (SC) injection in patients with relapsing or refractory EGPA on corticosteroid therapy with or without stable immunosuppressive therapy. All patients who complete the 52-week double-blind treatment period on IP may be eligible to continue into an open label extension (OLE) period. The OLE period is intended to allow each patient at least 1 year of treatment with open-label benralizumab 30 mg administered SC (earlier enrolled patients may therefore be in the OLE for longer than 1 year).
NCT05376319
The purpose of this study is to evaluate the efficacy and safety of obinutuzumab for the treatment of proteinase 3 Anti-Neutrophil Cytoplasmic Antibody (ANCA)-Associated Vasculitis (PR3-AAV).
NCT07551310
Peripheral giant cell granuloma (PGCG) is a non-neoplastic inflammatory lesion of gingival tissues. This study aims to evaluate and compare lymphocyte subpopulations in PGCG tissues and adjacent healthy gingival tissues obtained from the same individuals. A total of 28 systemically healthy, non-smoking patients diagnosed with PGCG are included in this study. Biopsy samples are collected during surgical excision of PGCG lesions, and corresponding healthy gingival tissues are obtained from the same patients. Immunohistochemical analysis is performed to assess lymphocyte subpopulations, including CD3, CD4, CD8, CD20, and CD79a. The proportions of these cells are compared between diseased and healthy tissues.
NCT01384513
This phase II trial studies how well reduced intensity donor stem cell transplant works in treating patients with hematologic malignancies. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.
NCT02108028
Background: \- There are very few documents to help young adults living with advanced cancer discuss their concerns and end-of-life preferences. A new document, Voicing My CHOiCES, allows young adults to explain what kind of care they would want if they became unable to communicate or make medical decisions on their own. Researchers want to study if this document is helpful. Objective: \- To study if Voicing My CHOiCES(TM) can reduce anxiety, improve sense of support, and improve communication about advanced care planning. Eligibility: \- Adults 18 to 39 years old being treated for cancer. Design: * Participants will answer questions about their age, sex, employment, religion, health, and marital status. They will also complete several brief questionnaires: 1. General Anxiety Short Form 2. Peace, Equanimity and Acceptance in the Cancer Experience 3. Functional Assessment of Social Support 4. Quality of Communication 5. Prior Communication about Advanced Care Planning * Then a health care professional will introduce Voicing My CHOiCES . Participants will review the document and comment on parts they find relevant. They will also say if any important items are missing. Participants will complete 3 pages of the document with the assistance of a health care provider. They will be asked for positive and negative observations. * The second stage of the study will take place about 1 month later. Participants will repeat the brief questionnaires listed above. They will be asked if they shared any of the preferences they described when completing the 3 pages of Voicing My CHOiCES during visit 1 with a family member, friend, or health care provider. Research staff will ask the participant for permission to contact the people they spoke with in order to learn whether their conversations about the document were helpful. They will ask for feedback on how to make Voicing My CHOiCES more helpful.
NCT02757911
X-linked chronic granulomatous disease (X-CGD) is a rare genetic disorder, which affects boys. It is a primary immunodeficiency disorder which results from an inability of the white blood cells called phagocytic cells (or phagocytes) to kill invading bacteria and fungi. These cells have difficulty forming the free radicals (most importantly the superoxide radical due to defective phagocyte NADPH oxidase complex) which are important in the killing of ingested pathogens. In X-CGD (which accounts for two thirds of CGD patients), the defect lies in a gene which makes up a critical part of the NADPH-oxidase complex (the catalytic subunit; gp91-phox protein). Therefore they kill bacteria and fungi poorly, and the patients suffer from severe and recurrent infections. This also results in inflammation which can damage parts of the body such as the lung and gut. In many cases, patients can be adequately protected from infection by constant intake of antibiotics. However, in others, severe life-threatening infections break through. In some cases, inflammation in the bowel or urinary systems results in blockages which cannot be treated with antibiotics, and which may require the use of other drugs such as steroids. Development of curative treatments for CGD is therefore of great importance.
NCT01167491
The investigators recently showed an abnormal expansion of NK-like CD4+ T cells in Wegener's granulomatosis (WG), mainly in the diffuse vasculitis presentation. These cells expressed an assortment of activating NK cell receptors and their signaling partners, in particular DAP12. The investigators hypothesize that DAP12, or a downstream signaling target of DAP12, is the missing link between the different cell components involved in WG (neutrophils, macrophages, CD4 T cells).
NCT07496060
The goal of this clinical trial is to compare the efficacy and safety of two different topical corticosteroids in 66 pediatric patients with active anterior chamber granuloma. The main questions it aims to answer are: * Does Loteprednol Etabonate 1% provide equivalent inflammation control and granuloma resolution compared to Prednisolone Acetate 1% over a 3-month period? * Does Loteprednol Etabonate 1% result in a lower frequency of steroid-related intraocular pressure (IOP) elevations than Prednisolone Acetate 1%? Researchers compared a group receiving Loteprednol Etabonate 1% four times daily to a group receiving Prednisolone Acetate 1% six times daily to see if Loteprednol could maintain comparable therapeutic effectiveness while offering a safer intraocular pressure profile. Participants will Be randomized to receive either Loteprednol Etabonate 1% or Prednisolone Acetate 1% eye drops. Follow a specific dosing schedule (4 times/day for Loteprednol or 6 times/day for Prednisolone). Undergo a clinician-guided medication tapering schedule based on clinical response. Attend follow-up assessments at day 1, 2 weeks, 1 month, and 3 months for eye examinations and pressure monitoring. Be referred for surgical management if they do not demonstrate adequate clinical improvement after 4 weeks of therapy.
NCT00368446
Healthy volunteers and patients with diseases that involve problems clearing mucus from the lungs will be examined and tested to better understand the reasons for recurring lung infections in these patients and to try to develop better ways to diagnose and treat them. The study will also try to identify the genes responsible for these diseases. Healthy volunteers 18 years of age and older and patients 2 years of age or older with suspected primary ciliary dyskinesia (PCD), variant cystic fibrosis (CF) or pseudohypoaldosteronism (PHA) may be eligible for this study. Patients enrolled in the Natural History Study of Nontuberculous Mycobacteria at NIH or other NIH natural history protocols may also be enrolled. Participants undergo the following tests and procedures during a 1-day visit at the NIH Clinical Center, as follows: All patients and normal volunteers have the following procedures: * Physical examination and review of medical and genetic history and family genetic history. * Lung function test and measurement of oxygen saturation level. * Nitric oxide measurement to measure the amount of nitric oxide production in the nose: A small tube is placed in the nose while the subject breathes through the mouth into a cardboard tube. All patients have the following additional procedures: * Blood tests for liver and kidney function, blood count, immunoglobulins and pregnancy test (where appropriate). * Blood test or buccal scrape (brushing the inside of the cheek) to obtain DNA to look for gene mutations that cause PCD, CF or PHA. * Scrape biopsy of cell lining the inside of the nose: A small toothpick-sized plastic stick with a tiny cup on the end is used to get nasal lining cells to look at the cilia (hair-like structures that move mucus). * Semen analysis (in some men) to test sperm tail function or structure. Patients suspected of having a variant of CF or PHA, including nontuberculous mycobacterial lung disease, have the following additional procedures: * Sweat chloride test: A medicine is placed on the arm to produce sweat; then, a very low level of electric current is applied for 5 to 12 minutes. Sweat is collected in a plastic tube and tested for salt content. * Blood draw for CF genetic testing, if necessary, and to measure levels of the enzyme trypsin. * Saliva collection to measure sodium and chloride content. * Nasal potential difference to measure the electrical activity of the cells lining the inside of the nose: A soft plastic tube filled with a salt solution is passed into the nasal passage and a sterile needle is placed under the skin of the arm. This test provides information about how the lining of the nose is able to get used to changes in temperature and humidity. (Normal volunteers also have this test.)
NCT02116764
This study is a longitudinal and cross-sectional evaluation of patients with Chronic Granulomatous Disease (CGD) who received or are receiving hematopoietic cell transplantation (HCT) for their disease under a variety of protocols used by participating institutions compared to a control non-HCT group receiving standard care. Investigators at multiple centers caring for patients with CGD in North America and 3 centers in Europe will participate. Patients with CGD will have been treated according to institutional practice and protocols. Investigators will enroll these patients as subjects in this protocol. This study will investigate which patients benefit most from HCT, and what types of transplants are optimal for patients with CGD, in the context of overall outcomes in CGD patients with and without transplant....
NCT05463133
Background: Chronic granulomatous disease (CGD) affects the immune system. People with CGD are more likely to get infections. Drugs can help control infections, but these treatments can cause side effects including kidney failure and deafness. Stem cell transplants can cure CGD, but these don t always work. Objective: To find out if a different drug treatment can improve the success rates of stem cell transplants in people with CGD. Eligibility: People aged 4-65 years with CGD. Design: Participants will undergo screening. They will have a physical exam. They will have blood and urine tests and tests of their heart function and breathing. They will have imaging scans. They will have a bone marrow biopsy; a needle will be inserted into their hip to draw a sample of tissue from the bone. A tube called a catheter will be placed into a vein in the participant s chest. This catheter will remain in place for the transplant and recovery period. Blood for tests can be drawn from the catheter, and medications and the stem cells can be administered through it. Participants will be in the hospital for either 10 or 21 days to receive 3 or 4 drugs before the transplant. They will get 2 doses of total body radiation on the same day. Participants will receive donor stem cells through the catheter. They will remain in the hospital for 6 weeks afterward. Participants will visit the clinic 2 to 3 times per week for 3 months after discharge. Follow-up visits will continue for 5 years.
NCT02213913
This phase I/II trial studies the side effects and best dose of lenalidomide when given together with combination chemotherapy and to see how well they work in treating patients with v-myc myelocytomatosis viral oncogene homolog (avian) (MYC)-associated B-cell lymphomas. Lenalidomide may stop the growth of B-cell lymphomas by blocking the growth of new blood vessels necessary for cancer growth and by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Giving lenalidomide together with combination chemotherapy may be an effective treatment in patients with B-cell lymphoma.
