Filter by:The rationale for this retrospective study is to evaluate the efficacy and safety of thrombopoietin-receptor agonist (TPO-RA) romiplostim for reducing thrombocytopenia and bleeding tendency in pediatric participants with genetically confirmed Wiskott-Aldrich syndrome (WAS).
In this study, the investigators test 2 dose levels of thiotepa (5 mg/kg and 10 mg/kg) added to the backbone of targeted reduced dose IV busulfan, fludarabine and rabbit anti-thymocyte globulin (rATG) to determine the minimum effective dose required for reliable engraftment for subjects undergoing hematopoietic stem cell transplantation for non-malignant disease.
WAS is a rare primary immune deficiency disease caused by genetic mutation and is more common in males than females. The purpose of this study is to understand experiences of WAS subjects and caregivers to identify important concepts of interest that could be measured in future Phase IIIb trials. This is a qualitative cross-sectional study that will include a sample of approximately, 8 subjects with WAS and 13 caregivers of subjects with a diagnosis of WAS in the United States, United Kingdom and France. A 60 to 90 minute open-ended interview will be conducted over the telephone or video conference that will be audio-recorded for subsequent transcription. The aim of these interviews is to obtain subject and caregiver perspectives on the impact of WAS and its associated treatments on quality of life and experiences of living with WAS.
Many genetic diseases of lymphohematopoietic cells (such as sickle cell anemia, thalassemia, Diamond-Blackfan anemia, Combined Immune Deficiency (CID), Wiskott-Aldrich syndrome, chronic granulomatous disease, X-linked lymphoproliferative disease, and metabolic diseases affecting hematopoiesis) are sublethal diseases caused by mutations that adversely affect the development or function of different types of blood cells. Although pathophysiologically diverse, these genetic diseases share a similar clinical course of significant progressive morbidity, overall poor quality of life, and ultimate death from complications of the disease or its palliative treatment. Supportive care for these diseases includes chronic transfusion, iron chelation, and surgery (splenectomy or cholecystectomy) for the hemoglobinopathies; prophylactic antibiotics, intravenous immunoglobulin, and immunomodulator therapies for the immune deficiencies; and enzyme replacement injections and dietary restriction for some of the metabolic diseases. The suboptimal results of such supportive care measures have led to efforts to implement more aggressive therapeutic interventions to cure these lymphohematopoietic diseases. The most logical strategies for cure of these diseases have been either replacement of the patient's own hematopoietic stem cells (HSC) with those derived from a normal donor allogeneic bone marrow transplant (BMT) or hematopoietic stem cell transplant (HSCT), or to genetically modify the patient's own stem cells to replace the defective gene (gene therapy).
Wiskott - Aldrich syndrome (WAS) is a rare serious medical condition that causes problems both with the immune system and with easy bruising and bleeding. The immune abnormalities cause patients with WAS to be very susceptible to infections. Depending on the specific type of primary immune deficiency diseases, there are effective treatments, including antibiotics, cellular therapy and gene therapy, but studies of large numbers of patients are needed to determine the full range of causes, natural history, or the best methods of treatment for long term success. This multicenter study combines retrospective, prospective and cross-sectional analyses of the transplant experiences for patients with WAS who have already received HCT since 1990, or who will undergo Hematopoietic cell transplant (HCT) during the study period. The retrospective and prospective portions of the study will address the impact of a number of pre and post-transplant factors on post-transplant disease correction and ultimate benefit from HCT and the cross-sectional portion of the study will assess the benefit of HCT 2 years post-HCT in consenting surviving patients.
Background: - People with primary immune deficiency diseases (PIDD) have weak immune systems. This makes it hard for their bodies to fight infection. The Immune Deficiency Foundation has a network to collect data about people with PIDD. It is called the United States Immunodeficiency Network. It will help doctors and scientists better understand these disorders. The goal is to get medical data for everyone with these disorders in the U.S. and Canada. Data will be stored in a registry. Researchers can use it to study if these disorders are increasing. They can also learn how the disorders are diagnosed and treated. Objectives: - To collect data on people with primary immune deficiency disorders. Eligibility: - People who have a PIDD. Design: - Data can be added with no record of personal identity. - Data can be added with identity kept separate. This data will be linked to the registry by a code number. - Data for the registry includes: - Family history - Disease treatment - Disease characteristics - Medical history - Laboratory data
This is a single arm, phase I study to assess the tolerability of abatacept when combined with cyclosporine and mycophenolate mofetil as graft versus host disease prophylaxis in children undergoing unrelated hematopoietic stem cell transplant for serious non-malignant diseases as well as to assess the immunological effects of abatacept. Participants will be followed for 2 years.
This phase II trial studies how well giving fludarabine phosphate, melphalan, and low-dose total-body irradiation (TBI) followed by donor peripheral blood stem cell transplant (PBSCT) works in treating patients with hematologic malignancies. Giving chemotherapy drugs such as fludarabine phosphate and melphalan, and low-dose TBI before a donor PBSCT helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from the 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. Sometimes the transplanted cell from a donor can make an immune response against the body's normal cells. Giving tacrolimus, mycophenolate mofetil (MMF), and methotrexate after transplant may stop this from happening
This is phase I/II protocol to evaluate the safety and efficacy of WAS gene transfer into hematopoietic stem/progenitor cells for the treatment of Wiskott Aldrich Syndrome.
