6 Clinical Trials for Hypogammaglobulinemia
The main purpose of this study is to see if IgPro20 can prevent infection in people with multiple myeloma (MM) who have hypogammaglobulinemia from receiving bispecific monoclonal antibodies (BsAbs).
The primary purpose of the study is to evaluate whether biweekly administered XEMBIFY® plus Standard Medical Treatment (SMT) over a one-year period will reduce the rate of major bacterial infections per participant per year in B-cell CLL, MM, and NHL participants with hypogammaglobulinemia (HGG) in comparison to the Placebo plus SMT group.
This study hypothesizes that a reduced intensity immunosuppressive preparative regimen will establish engraftment of donor hematopoietic cells with acceptable early and delayed toxicity in patients with immune function disorders. A regimen that maximizes host immune suppression is expected to reduce graft rejection and optimize donor cell engraftment.
The purpose of this study is to assess efficacy, safety and pharmacokinetics of Kedrion Immunoglobulin 10% (KIg10) in pediatric patients with Primary Immunodeficiency Disease (PID).
Background: * WHIMS (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis Syndrome) is caused by various genetic changes that increase the activity of the chemokine receptor, CXCR4. Excessive function of this receptor causes mature neutrophils (part of the white blood cells) to be retained within the bone marrow rather than being released to the blood and is one of the causes of severe inherited neutropenia (low white blood counts). In neutropenia, the body is less able to fight off infection. Patients with WHIMS usually are at risk for skin, soft tissue, sinus, and lung infections, which can result in loss of hearing, teeth, and lung function. * Current treatment for WHIMS consists of regular injections of a white blood cell growth stimulating medication called granulocyte colony stimulating factor (G-CSF), and supplemental immunoglobulin (antibody). These therapies are expensive, nonspecific, have significant side effects and toxicities, and do not fully correct all problems, especially warts and cancers related to human papillomavirus (HPV). * A drug called Mozobil has been approved for use in combination with G-CSF to increase the number of stem cells that can be collected prior to bone marrow transplantation. Mozobil may offer a specific and well-tolerated new treatment for WHIMS and other syndromes characterized by neutropenia. Objectives: * To evaluate whether Mozobil is safe and effective to treat neutropenia (low white blood cell count) in patients with WHIMS. * To determine an appropriate treatment dose of Mozobil, within currently approved dosage levels. Eligibility: - Individuals between 18 and 75 years of age who have been diagnosed with WHIMS and have a history of severe infections. Design: * Potential participants will undergo a screening with a medical history, physical examination, questionnaire, heart and lung function scans, and blood and urine samples. Tests will also be done for hepatitis B and C virus, and human immunodeficiency virus (HIV) that causes acquired immunodeficiency syndrome (AIDS), as well as to check neutrophil function. * Patients who are being treated with G-CSF will stop injections for 2 days before being admitted to the National Institutes of Health (NIH) Clinical Center. * Patients may participate in a Dose Escalation study and receive increasing doses of Mozobil over 5 days of treatment until their white blood cell count improves sufficiently or the maximum approved dose is reached. Blood samples will be taken regularly throughout the treatment process. Patients will then receive an additional dose of Mozobil at the maximum approved dose or the dose sufficient to cause improvement, before restarting the G-CSF injections. * Patients may also participate in a long-term Chronic Dosing study and receive Mozobil once or twice a day for up to a maximum of 60 months.
This study aims to understand the causes and progression of Common Variable Immunodeficiency (CVID) and related inborn errors of immunity (IEI). These are conditions where the immune system does not function properly, leading to frequent infections and other complications such as gastrointestinal inflammation, lung and liver disease, autoimmune conditions, and an increased risk of certain cancers. By studying patients with CVI and related immune disorders, we hope to develop better ways to diagnose, treat, and prevent complications associated with these conditions. Patients diagnosed with CVID or related immune disorders must be referred by their physician and medical records reviewed by the study team to confirm eligibility to participate in this study. Once enrolled, participants will undergo various tests, including blood draws, physical exams, and imaging studies like CT scans to track changes over time. We may collect samples such as blood, urine, stool, or saliva for research purposes. If a surgical procedure or biopsy is performed because it is medically necessary, we may collect an additional sample for research testing. Family members of patients may be asked to provide blood samples for comparison. Some tests may be done remotely if participants or family members cannot travel to the study site. Who Can Participate * Patients diagnosed with CVI or related IEI, such as X-linked agammaglobulinemia, Blau Syndrome or Yao Syndrome. * Participants must be at least 2 years old. * Family members of patients may include parents, siblings, grandparents, children, aunts, uncles, and cousins. * Pregnant women already enrolled in the study will continue to participate, but new pregnant participants will not be enrolled. Potential Risks and Benefits * Risks: Blood draws may cause discomfort, bruising, or infection. Apheresis may cause dizziness, nausea, or muscle cramps; this procedure is to collect specific cells in the blood and is infrequently done on this protocol. Extra biopsies during clinically indicated procedures may increase the risk of complications; they will only be collected after the medically necessary biopsies are taken and if it is safe to collect any extra biopsies. * Benefits: Participants may not receive direct medical benefits, but the study will contribute to a better understanding of CVID and related conditions, potentially leading to improved treatments.
