Active clinical trials for "Common Variable Immunodeficiency"

The purpose of this study is to discover if differences in the surface markers of B-cells (antibody producing cells of the immune system) in Common Variable Immune Deficiency (CVID) are related to CVID or its complications/treatment (e.g. bronchiectasis, granulomatous disease, immunoglobulin treatment). The study hypothesis is that the altered B-cell surface markers are related to CVID, and not to the complications or treatment of CVID.

This study will explore the cause of immunodeficiency in common variable immunodeficiency (CVI) and other related immunodeficiency syndromes-IgA deficiency, hyper IgM syndrome, thymoma and agammaglobulinemia, hypogammaglobulinemia associated with Epstein-Barr infection, and others to better focus on how to correct the underlying defect. Patients with CVI and their family members may participate in this study. Family members must be between the ages of 18 and 85, in good health and weigh at least 110 pounds. Patients will receive standard medical care for their illness. Procedures may include a medical history and physical examination, routine blood tests, stool examination for infectious agents, lung function tests, chest and sinus X-rays. Treatment may include administration of immune serum globulin, antibiotics for infections, and anti-inflammatory drugs, if needed. In addition, patients may undergo the following: Lymphapheresis: This procedure is done to collect large numbers of white blood cells (lymphocytes). Blood is collected through a needle in an arm vein, similar to donating blood. The blood is separated it into its components by centrifugation (spinning), the white cells are removed, and the rest of the blood (red cells, plasma and platelets) is returned to the body, either through the same needle or through another needle in the other arm. Blood draw: Blood may be drawn through a needle in an arm vein (venipuncture). No more than 450 milliliters (15 ounces) of blood will be collected over a 6-week period from adults, and no more than 7 ml (1 1/2 teaspoons) per kilogram (2.2 pounds) of body weight in children over the same time period. Lymph node biopsies: Lymph node biopsies will be done only if required for diagnostic purposes. Some of the biopsy tissue may be kept for research. Up to two lymph nodes may be removed during each procedure. For the procedure, a painkiller is injected into and beneath the skin in the biopsy area, and the node is removed surgically. The incision is closed using dissolving sutures (stitches) that do not require removal. The biopsy takes about 30 minutes. Patients will be hospitalized at least overnight for observation. Intestinal biopsies: Endoscopy and gastrointestinal biopsy will be done only if there is evidence of malabsorption. Some of the biopsy tissue may be kept for research. Patients are pre-medicated to allay anxiety, but are fully conscious during the procedure. A flexible tube is inserted into the stomach or small intestine through the mouth. The tube allows the doctor to see the intestinal mucosa and to project the image onto a TV screen. At various places in the mucosal surface, small pieces of tissue are plucked out using a small space at the tip of the endoscope. The procedure takes 30 to 60 minutes. Some of the blood collected may be used for genetic tests. Some blood and tissue samples may be stored for future research labeled with a code, such as a number, that only the study team can link to the patient. Participating family members will provide a medical history, and their pulse, blood pressure and temperature will be taken. They will have 10 to 120 ml (1/3 to 4 ounces) of blood drawn from a vein in the arm. Blood samples may be taken on repeated occasions as long as the relative remains in the study. The blood will be used for research that may involve development of diagnostic tests for CVI, evaluation of the structure and function of normal blood cells for comparison with those of patients with CVI, and studies to try to determine possible genetic factors involved in susceptibility to CVI.

The goal of our study is to assess the cellular immune responses of participants with antibody deficiency disease before and after immunization with SARS-CoV-2 mRNA vaccines.

OBJECTIVES: I. Provide curative immunoreconstituting allogeneic bone marrow transplantation for patients with primary immunodeficiencies. II. Determine relevant outcomes of this treatment in these patients including quality of survival, extent of morbidity and mortality from complications of the treatment (e.g., graft versus host disease, regimen related toxicities, B- cell lymphoproliferative disease), and completeness of functional immunoreconstitution.

The objective of this study is to assess the efficacy and safety of Vivaglobin in previously untreated patients (PUPs) with primary immunodeficiency (PID) over a 25-week observation period. The purpose is to investigate whether PUPs will respond to subcutaneous immunoglobulin (SCIG) treatment with adequate trough levels without first receiving immunoglobulins by the intravenous route by demonstrating that 100 mg immunoglobulin G/kg body weight (IgG/kg bw) administered on 5 consecutive days (i.e. resulting in a total dose of 500 mg IgG/kg bw) results in an IgG increase to ≥ 5 g/L on Day 12 after initiation of SCIG therapy.

This study will determine whether an experimental medicine, STA-5326 mesylate, is safe to use in patients with common variable immunodeficiency (CVID) who have inflammation of the gut. It will also determine if patients who take this drug show improvement in their symptoms, decrease in inflammatory chemicals in the gut, changes in their immune cells, and improvement in how their gut is functioning to absorb food. Patients between 18 and 75 years of age with CVID and chronic diarrhea or involuntary weight loss of more than 5 percent of their past body weight over the past 12 months may be eligible for this study. Candidates are screened with a review of their medical records, a medical history and physical examination, blood, urine and stool tests, chest x-rays and skin test for exposure to tuberculosis, and a hydrogen breath test. For the latter, breath samples are collected before and every 20 minutes (for 2 hours) after the subject drinks a sugar solution. This test determines the digestive effects of bacteria in the upper intestine. Samples are collected by having the subject blow into a balloon. Participants undergo the following tests and procedures: Immune System and Gastrointestinal Evaluation 48-hour stool fat collection (measures the amount of undigested fat in the stool): Subjects keep a diary of what they eat for a 48-hour period. At the beginning of the 48 hours they take two dye capsules and then take another two capsules 48 hours later. They collect a stool sample when they pass the second set of capsules in their bowel movement. An additional 24-hour stool collection is tested for loss of protein in the stool. D-xylose absorption test (measures the ability of the gut to absorb nutrients): Subjects drink a solution of d-xylose (a sugar substitute). Blood samples are collected before and 1 hour after drinking the solution. Upper endoscopy: A thin flexible lighted tube is advanced through the mouth to evaluate the esophagus, stomach and beginning of the small intestine. Lower endoscopy: A thin flexible lighted tube is advanced through the rectum to evaluate the colon. Treatment Period (Study days 1 to 57) Physical examination - study days 1, 8, 15, 29, 43 and 57 Blood samples to test the levels of STA-5326 in the blood. On study days 1 and 57, samples are collected before the medication dose and 1, 2, 4, 6 and 8 hours after the dose; on day 29, one sample is collected before the medication dose. Blood samples for routine safety testing - study days 1, 8, 15, 29, 43 and 57 Medication history - study days 1, 8, 15, 29, 43 and 57 Interview about pain, discomfort, and well being - study days 1, 8, 15, 29, 43 and 57 Pregnancy test for women who can become pregnant - study days 15, 43, and 57 D-xylose absorption test - study days 29 and 57 Electrocardiogram - study days 29 and 57 Urine test - study days 29 and 57 Blood test for research on immune cells - study day 57 Repeat endoscopies and studies of gut function (24- and 48-hour stool collections) Follow-up period (Day 85 and day 113) -Physical examination, blood tests, medication history, questions about pain, discomfort and well being

This aim of this research project is to determine if low to moderate level exercise can have an impact on stress, fatigue, and quality of life for individuals diagnosed with a primary immunodeficiency disease. This 8-week study will compare participants engaging in a semi-customized, home exercise program (exercise intervention group) to participants performing normal activities (non-exercise control group). This study will track stress, fatigue, and quality of life in individuals with a diagnosis of primary immunodeficiency disease, using standardized questionnaires, journals, and interviews.

The main objective of this study is to see if GAMMAPLEX is efficacious with respect to Food and Drug Administration (FDA) minimal requirements (no more than 1 serious, acute, bacterial infection per subject per year) in subjects with Primary Immunodeficiency Diseases (PID). The secondary objectives are to assess the safety and tolerability of GAMMAPLEX and to determine if GAMMAPLEX has a pharmacokinetic (PK) profile comparable with that of intact Immunoglobulin G (IgG) in subjects with PID.

The objectives of this trial are the assessment of safety and efficacy of IgPro10 in patients with PID, and the assessment of tolerability of high infusion rates. To demonstrate safety, the number of infusions temporally associated with AEs, the rate, severity and relationship of all AEs and the vital sign changes during each infusion will be evaluated.
