Active clinical trials for "Primary Immunodeficiency Diseases"

The main aim of this study is to evaluate the PK, safety, tolerability and immunogenicity of subcutaneous (SC) administration of TAK-881 in adult and pediatric participants with PIDD and compare them to HYQVIA in participants 16 years old and older. The participants will be treated with TAK-881/HYQVIA or HYQVIA/TAK-881 with the same dose and dosing interval of immunoglobulin for up to 51 weeks (for participants greater than or equal to [>=]16 years) and only with TAK-881 for up to 27 weeks (for participants aged 2 to less than [<]16 years) as they were treated with another immunoglobulin before enrollment. Participants will need to visit the clinic every 3 or 4 weeks during the duration of the study.

Patients with medical conditions requiring allogeneic hematopoietic cell transplantation (allo-HCT) are at risk of developing a condition called graft versus host disease (GvHD) which carries a high morbidity and mortality. This is a phase I/II study that will test the safety and efficacy of hematopoietic cell transplantation (HCT) with ex-vivo T cell receptor Alpha/Beta+ and CD19 depletion to treat patients' underlying condition. This process is expected to substantially decrease the risk of GvHD thus allowing for the elimination of immunosuppressive therapy post-transplant. The study will use blood stem/progenitor cells collected from the peripheral blood of parent or other half-matched (haploidentical) family member donor. The procedure will be performed using CliniMACS® TCRα/β-Biotin System which is considered investigational.

This study aims to compare the maximal exercise capacity, functional exercise capacity, respiratory functions, physical activity level, quality of life, respiratory muscle strength and endurance, peripheral muscle strength, muscle oxygenation and dyspnea in children with primary immunodeficiency (PID) and healthy individuals. The study was designed as a cross-sectional study on 26 patients diagnosed with primary immunodeficiency and 26 age- and sex-matched healthy individuals. Differences between both groups will be evaluated statistically. The results of this study aim to reveal how primary immunodeficiency patients are affected by factors such as respiratory functions, physical activity level and quality of life

This is a data collection study that will examine the general diagnostic and treatment data associated with the reduced-intensity chemotherapy-based regimen paired with simple alemtuzumab dosing strata designed to prevented graft failure and to aid in immune reconstitution following hematopoietic stem cell transplantation.

In the prospective part of the study, patients diagnosed with PID will receive replacement therapy with Cutaquig for at least 6 months and will be randomised with the help of physicians of the Russian PID Registry. At the beginning of the study, data on the prior intravenous immunoglobulin (IVIG) therapy efficacy will be extracted from patients' medical records (retrospective part of study). Also, at the beginning of the study, patients or their parents will be asked to complete Quality of Life Questionnaire for children, version 4.0; short form in Russian - Pediatric Quality of Life Inventory Russian, Version 4.0 (Russia), PedSQL (Appendix 14.1). During the 6 months of treatment with Cutaquig, investigators will enter information on infectious episodes, IgG levels (at least 3 times during the study period), and definition of an adverse drug reaction / serious adverse drug reaction, in the database. After 6 months, patients/their parents will be asked to complete the PedSQL, Quality of Life Questionnaire again. If the patient continues to receive the drug, and patient and his/her legally acceptable representatives (for patients under 14 years of age) agree to continue participating in the study, similar information will be collected for another 6 months. The first 6 months are planned for the main study period, 6-12 months for an extended study period. Data obtained in the prospective phase of the study will be compared with similar data obtained in the retrospective phase in the same patients

This study will assess the relative safety, tolerability, and participant satisfaction in participants using the rapid manual push method with Cutaquig®. The hypothesis being that treatment with Cutaquig® by rapid manual push method will improve the safety, tolerability and patient satisfaction of participants with PID or SID. Cutaquig® by rapid push is already approved in Canada and has proven to be efficacious in preventing significant infection. However, relative safety, tolerability, and patient satisfaction have not been studied in these patients. The information gained from this study will improve the safety and tolerability knowledge database and will support the optimal use of Cutaquig® - thus benefitting both physicians and patients.

Though common, morbidities related to upper airway disease in primary ciliary dyskinesia (PCD) and primary immunodeficiencies (PID) have not been fully characterized. These conditions can be difficult to distinguish due to their overlapping phenotypes. The sinonasal and middle ear features are often identified as most problematic by patients and their families, and optimal, highly effective treatment regimens have not been established. The main objective of this project is to characterize and compare the upper airway phenotypes in individuals with confirmed diagnosis of PCD and PID, and to collect critical data to inform the design of future clinical trials of treatment of the upper airway diseases. The investigators anticipate that these investigations will discern the clinical, anatomical, and pathophysiological phenotypes of paranasal sinus disease in PCD and PID, identifying disease endpoints and biomarkers that differentiate these two overlapping disorders. Findings from these studies will also enhance our understanding of middle ear disease and associated hearing loss in a cross-sectional cohort of patients with PCD and PID. Ultimately, the long-term goal of our Consortium is to elucidate underlying phenotypes and genotypes of these diseases, potentially leading to novel therapeutics that will improve the lives of affected individuals. Given the COVID pandemic, certain procedures will have the option to be converted to telehealth visits to ensure compliance with local guidelines and participant safety.

Background: Genetic testing called "sequencing" helps researchers look at DNA. Genes are made of DNA and are the instructions for our bodies to function. We all have thousands of genes. DNA variants are differences in genes between two people. We all have lots of variants. Most are harmless and some cause differences like blue or brown eyes. A few variants can cause health problems. Objective: To understand the genetics of immune disorders various health conditions, as well as outcomes of clinical genomics and genetic counseling services performed under this protocol. Eligibility: Participants in other NIH human subjects research protocols - either at the NIH Clinical Center (CC) or at Children s National Health System (CNHS) - (aged 0-99 years), and, in select cases, their biological relatives Design: Researchers will study participant s DNA extracted from blood, saliva, or another tissue sample, including previously collected samples we may have stored at the NIH. Researchers will look at participant s DNA in great detail. We are looking for differences in the DNA sequence or structure between participants and other people. Participants will receive results that: Are important to their health Have been confirmed in a clinical lab Suggest that they could be at risk for serious disease that may affect your current or future medical management. Some genetic information we return to participants may be of uncertain importance. If genetic test results are unrelated to the participant s NIH evaluations, then we will not typically report: Normal variants Information about progressive, fatal conditions that have no effective treatment Carrier status (conditions you don t have but could pass on) The samples and data will be saved for future research. Personal data will be kept as private as possible. If future studies need new information, participants may be contacted.

Background: The immune system is the part of the body that fights infection. Some people have immune deficiencies that cause skin rashes, make them get sick often with infections, or make it difficult for their skin to heal. Researchers want to learn more to better treat conditions that affect immune response. Objective: To learn about how the immune system and skin healing are related to each other. Eligibility: People ages 18-75 with primary immune deficiency, eczema, or psoriasis. Healthy volunteers are also needed. Design: Participants will be screened with a medical and medicine history and a physical exam. They may take a pregnancy test. Participants will discuss the medicines or supplements they take as well as skin products they use, such as soaps and lotions. Participants will have up to 4 skin biopsies taken from the forearm. A needle will inject an anesthetic into the skin where the biopsy will be done. A sharp tool that looks like a tiny cookie cutter will be used to remove a round plug of skin a bit smaller than the tip of a pencil. Participants will give at least 1 blood sample. Participants may have optional skin swab collection. A cotton swab will be used to swab the skin on the arm. Participants may have optional skin tape collection. A sticky strip of tape will be placed on the arm and then removed. Participants may give leftover samples taken as part of their regular medical care. Participation will last for about 4 days. Participants will have 2 visits that each last about 1 hour. They may be asked to repeat the study in the future.

Background: - Researchers are interested in studying disorders that make individuals more susceptible to fungal infections, specifically infections with the Candida yeast. These disorders are often related to problems with the immune system and may have genetic factors, which suggests that researchers should study not only the individual with the disorder, but also his or her first- and second-degree relatives (such as parents, siblings, children, and first cousins). To provide material for future research, individuals with immune disorders and their first- and second-degree relatives will be asked to provide blood and other samples for testing and comparison with samples taken from healthy volunteers with no history of immune disorders. Objectives: - To collect blood and other biological samples to study immune disorders that make individuals more susceptible to fungal infections. Eligibility: Individuals of any age who have abnormal immune function characterized by recurrent or unusual fungal infections, recurrent or chronic inflammation, or other types of immune dysfunction. First- or second-degree genetically related family members (limited to mother, father, siblings, grandparents, children, aunts, uncles, and first cousins). Healthy volunteers at least 18 years of age (for comparison purposes). Design: Participants will provide blood samples and buccal (cells from the inside of the mouth near the cheek) samples. Participants with immune disorders will also be asked to provide urine samples, saliva or mucosal samples, or skin tissue biopsies, and may also have imaging studies (such as x-rays) to collect information for research. Samples may be collected at the National Institutes of Health or at other clinical locations for the samples to the sent to the National Institutes of Health. No treatment will be provided as part of this protocol....
