Filter by:To investigate the presence of seconday of lymphoid organs in patients who underwent allogenic hematopoietic stem cell transplantation 15 to 45 years ago. The goal aims to assess the development of seconday lymphoid organs given the fact that the absence of myeloablation these patients present a split chimerism between T lymphocytes and the other leucocytes. Thus, they may not be able to generate seconday lymphoid organs. Practically, whole body MRI is being used to visualise and quantify both mediastinal and intraabdominal lymph nodes. Delta will be compared with those obtained in healthy age-matched individuals. It is scheduled to include 15 patients and 15 controls.
This registry is conducted in patients with adenosine deaminase severe combined immune deficiency (ADA-SCID) treated with Revcovi™ to collect periodic clinical and biochemical data on safety and dose adjustment.
This is a prospective, non-randomized, single-cohort, longitudinal, single-center, clinical study designed to assess the efficacy and safety of a cryopreserved formulation of OTL-101 (autologous CD34+ hematopoietic stem/progenitor cells transduced ex vivo with EFS (Elongation Factor 1α Short form) Lentiviral Vector (LV) encoding for the human ADA gene) administered to ADA-SCID subjects between the ages of >/=30 days and <18 years of age, who are not eligible for an Human Leukocyte Antigen (HLA) matched sibling/family donor and meeting the inclusion/exclusion criteria. The OTL-101 product is infused after a minimal interval of at least 24 hours following the completion of reduced intensity conditioning. For subjects who successfully receive the OTL-101 product, pegademase bovine (PEG-ADA) Enzyme Replacement Therapy (ERT) is discontinued at Day+30 (-3/+15) after the transplant. After their discharge from hospital, the subjects will be seen at regular intervals to review their history, perform examinations and draw blood samples to assess immunity and safety.
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.
STRIMVELIS is a medicinal product that restores adenosine deaminase (ADA) function in hematopoietic cell lineages, thereby preventing impaired immune function. STRIMVELIS is indicated for the treatment of patients with ADA- severe combined immunodeficiency (SCID), for whom suitable human leukocyte antigen (HLA)-matched related stem cell donor is not available. The objective of this study is to evaluate the effectiveness of routine and additional risk minimization measures by assessing the understanding of referring health care providers (HCPs) and parents/carers (hereby referred as participants) with regard to the specific risks associated with STRIMVELIS. In this cross-sectional study, surveys will be provided to referring HCPs and parents/carers of children approximately six months after treatment with STRIMVELIS. The study will recruit for approximately two years or until a maximum of 10 referring HCPs and 10 parents/carers have completed their respective surveys, whichever occurs first.

The OTL-101 product is infused after a minimal interval of at least 24 hours following the completion of reduced intensity conditioning. For subjects who successfully receive the OTL-101 product, pegademase bovine (PEG-ADA) Enzyme Replacement Therapy (ERT) is discontinued at Day+30 (-3/+15) after the transplant.

The goal of the proposed research is to observe the prevalence and establish the validity of a newborn screening method for severe combined immunodeficiency (SCID). The assay to be used is developed on the basis of PCR quantification of T-cell receptor excision circles (TRECs) that is absent in SCID patients, thus correlating with the disease.
Severe combined Immunodeficiencies ( SCID ) are a group of inherited diseases of the immune system by characterised profound abnormalities of T cell development . Infants with SCID require prompt clinical response to Prevent life -threatening infection and studies show significantly improved survival in babies Diagnosed at birth as a result of previous family history . SCID follows criteria for population -based newborn screening since it is asymptomatic at birth and fatal within the first year of life, the confirmation of the disease is easy, there is a curative treatment , and it is known that early stem cell transplantation improves survival . Quantification of TRECs (T- cell receptor excision circles ) in DNA extracted from Guthrie samples is a sensitive screening test for Specific and SCID . The investigators propose in this study to perform a neonatal screening of SCID , in a population of 200,000 babies over a period of two years . The investigators propose to study the clinical utility and cost effectiveness ratio, and SCID screening to demonstrate that could result in a broad benefit to Individuals detected , making screening relatively cost-effective in spite of the low incidence of the disease .
This is a clinical gene transfer study that aims to verify the safety and efficacy of the use of the EFS-ADA lentiviral vector to introduce the human adenosine deaminase (ADA) gene into the hematopoietic progenitors of patients affected with severe combined immunodeficiency due to ADA deficiency. The EFS-ADA vector expresses the human ADA cDNA under the control of the elongation factor alpha short promoter (EFS). In addition, this protocol will examine the effects of the ADA gene transfer on the immune system of treated patients. Patients with ADA deficiency and ineligible for matched sibling allogeneic bone marrow transplantation are eligible to participate in the study. To increase engraftment and selected advantage or gene-corrected cells, busulfan will be used as a cytoreductive agent. Enzyme replacement (PEG-ADA) will be discontinued 30 days after infusion of gene-corrected cells. CD34+ hematopoietic progenitors will be isolated from the patient bone marrow, peripheral blood or cord blood, exposed to lentiviral vector-mediated gene transfer and re-infused into the patient through a peripheral vein. Clinical, immunological and molecular follow-up studies will assess safety, toxicity, and efficacy of the procedure.
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
