Filter by: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.
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.
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.
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
The objective of this study is to determine if the safety and tolerability of Immune Globulin Intravenous (Human), 10% caprylate/chromatography (IGIV-C)purified is similar when infused at two different infusion rates. The primary objective is to compare the incidence and severity of all infusion related adverse events when IGIV-C, 10% is administered at a rate of 0.14 mL/kg/min compared to a rate of 0.08 mL/kg/min after a single daily infusion.
The purpose of this study is to demonstrate the effect of IgPro10 on the prevention of serious bacterial infections in patients with primary immunodeficiency. As secondary endpoints the rate of overall infections, the tolerability and safety of IgPro10 are studied. A part of the patients are participating in a pharmacokinetic substudy.
The purpose of this study is to demonstrate the effect of IVIG-F10 on the prevention of serious bacterial infections in patients with primary immunodeficiency. As secondary endpoints the rate of overall infections, the tolerability and safety of IVIG-F10 are studied.
This study will determine whether people with common variable immunodeficiency (CVID) with and without gastrointestinal (GI) symptoms have gut abnormalities (inflammation or loss of function) and changes in immune system cells and chemicals in the blood and gut. People with CVID have decreased levels of serum immunoglobulin IgG and IgA. Patients have sinus, lung and other infections, and many also have stomach and intestinal problems, such as chronic diarrhea, inability to absorb nutrition from food, and intestinal infections caused by bacteria. CVID patients with gastrointestinal symptoms 10 years of age and older may be eligible for this study; CVID patients without gastrointestinal symptoms 18 years of age and older will be enrolled as control subjects. Candidates will be screened with a review of their medical records, a medical history and physical examination, HIV blood test, stool sample, and hydrogen breath test. The breath test measures the amount of hydrogen in the breath after drinking sugar water, showing the digestive effects of bacteria in the upper intestine. Participants will be admitted to the NIH Clinical Center for several days to undergo the following procedures: - Medical history and physical examination - Blood tests - Urine and stool samples - 48-hour stool fat collection measures the amount of undigested fat in the stool to determine the ability of the gut to digest and absorb fat in the diet - D-Xylose absorption test measures the ability of a sugar compound to travel across the lining of the intestine to determine the ability of the gut to absorb nutrients - 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 lighted tube is advanced through the rectum to evaluate the colon Identification of GI abnormalities associated with changes in immune response in CVID patients will help in developing and testing new treatments for this disease.
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.
OBJECTIVES: I. Determine whether polyethylene-glycol-conjugated interleukin 2 (PEG-IL-2) can reduce the number of infections in patients with common variable immunodeficiency. II. Determine whether this therapy can improve lung functions in these patients with pulmonary impairment.
