Active clinical trials for "Severe Combined Immunodeficiency"

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 .

The purpose of the current study is to treat at least 3 ADA-SCID patients with OTL-101 prepared by the commercial manufacturing process.

This is a multi-institution, single arm, non-randomized pilot study coordinated by the Pediatric Blood and Marrow Transplant Consortium. Eligible patients will have severe combined immunodeficiency syndrome (SCID) or severe T-cell immunodeficiency disorder. Patients with these disorders do not have properly functioning immune systems. Without treatment, these disorders result in early childhood death. The standard treatment used for these diseases is to give the patient a stem cell transplant from a matched donor. The donor cells can be from a family member, an unrelated marrow donor or umbilical cord blood. The donor source will impact on transplant risks and approaches to the preparative regimen. There have been many different preparative regimens used for patients with SCIDS or severe T-cell immunodeficiency syndromes. Some patients have gotten no preparative regimen, while others have gotten only antithymocyte globulin (ATG; immune proteins made in horses that, when given, will kill lymphocytes). Still other patients have gotten conventional chemotherapy. In children treated with nothing or ATG alone, there is an increased risk of graft failure or only partial engraftment. When this happens, patients need life-long therapy with immunoglobulins to support the immune system. Children treated with chemotherapy generally have full immune recovery, but also may have major side effects from the chemotherapy. The side effects include infection, organ failure and infertility. This protocol, in combination with a parallel study with a separate preparative regimen, will attempt to answer the question of which patients with primary immunodeficiencies need a preparative regimen and what intensity is needed. Patients will be enrolled according to disease type and donor source. The purpose of this study is to see how much chemotherapy is actually needed for the transplant to work. To be able to do this and still make the transplant work, the drugs used to temporarily weaken the immune system will be strengthened. In groups, patients will be treated with lowering doses of the busulfan to find the lowest dose of this drug that is needed to get full immune recovery. The investigators hope this regimen will result in complete immune system recovery while limiting the side effects of chemotherapy. A second purpose of this study is to track the recovery of different parts of the immune system. The investigators also want to identify whether the recovery is coming from donor stem cells or from the patient. The patient will be admitted to the hospital to have the transplant and is expected to stay for up to 4 to 6 weeks. The preparative regimen will be made up of busulfan, fludarabine and antithymocyte globulin (ATG). After the preparative regimen, the cells from the donor will be given. To try and keep the patient's body from rejecting the donor cells and the donor cells from attacking the patient's body (graft-versus-host disease, or GVHD), cyclosporine will be given. The investigators will draw an extra 2 - 4 teaspoons of blood at specified time points to test for immune recovery and donor cell chimerism (the portion of the blood that belongs to the donor). Standard bone marrow transplant (BMT) clinical care will be provided with respect to pretransplant evaluation, peritransplant support, and posttransplant follow-up.

Study Design: SCID infants receiving an unconditioned haploidentical transplant will be started on Sirolimus (0.05 mg/kg/day) day -5 for Acute Graft-Versus-Host Disease (aGVHD) prophylaxis. Sirolimus levels will be monitored with goal sirolimus trough level of 5-8 ng/mL. Patients will be monitored for signs of aGVHD as defined by UCSF SOP CL 221.06 through day +100. Sirolimus will be tapered once T-regulatory cell to CD4 effector cell ratio is > or = 9%. Setting: Inpatient BMT Unit Benioff Children's Hospital at UCSF Medical Center Study Subjects: 15 infants with diagnosis of maternally engrafted T cells SCID by CA Newborn screen receiving unconditioned haploidentical HSCT Main Outcome Measures: Incidence of aGVHD (dermatitis, hepatitis, enteritis) as defined by SOP CL 221.06 by Day +100. Hypothesis 1. Patients placed on sirolimus prophylaxis will have lower incidence of aGVHD compared to historical controls. Hypothesis 2. Lower doses of sirolimus milligram per kilogram will be required to maintain goal troughs of 5-8 ng/mL.

Reduced intensity conditioning followed by allogeneic stem cell transplantation will result in mixed/complete donor chimerism and potentially alter the natural history and outcome of patients with non-malignant diseases.

The purpose of this study is to evaluate the safety and effectiveness of lentiviral gene transfer treatment at restoring immune function to participants with X-linked severe combined immunodeficiency (XSCID) who are 2 to 40 years of age, and have significant impairment of immunity.

Gene transfer for ADA-SCID using an improved lentiviral vector (TYF-ADA)

X-linked severe combined immunodeficiency (SCID-X1) is an inherited disorder that results in failure of development of the immune system in boys. This trial aims to treat SCID-X1 patients using gene therapy to replace the defective gene.

To date, allogeneic haematopoietic stem cell transplantation (aHSCT) is the only curative treatment for many paediatric and young adult haematological pathologies (acute leukaemia, myelodysplastic syndromes, haemoglobinopathies, bone marrow aplasia, severe combined immunodeficiency). Despite the major therapeutic progress made over the last 50 years, particularly in terms of supportive care, post-transplant morbidity and mortality remains high. Infectious complications, whose incidence varies between 30 and 60%, are the first cause of mortality in the immediate post-transplant period. In order to protect the patient from the occurrence of severe infectious episodes, aHSCTmust be performed in a highly protected environment (positive pressure chambers). This has implications for the experience and impact of hospitalization on the patient and family. This is particularly true in paediatrics, whether in children, adolescents or young adults, where it is not only the patient's quality of life that is at stake, but also their emotional and psychomotor development. In these patients, prolonged hospitalization (at least 6 weeks) in a sterile room will be responsible for physical deconditioning accompanied by a decrease in muscle mass, itself concomitant with undernutrition, and an increase in sedentary lifestyle. This prolonged hospitalisation in a sterile room, associated with myeloablative treatments, is therefore the cause of social isolation of patients, but it is also often synonymous with physical inactivity leading to a rapid decrease in physical condition, quality of life and an increase in fatigue. Today, the benefits of physical activity (PA) during and after cancer treatment have been widely demonstrated. The objective is to evaluate the feasibility of an adapted physical activity program during the isolation phase for achieving aHSCT in children, adolescents and young adults. This is a prospective, interventional, monocentric cohort study conducted at the Institute of Paediatric Haematology and Oncology in Lyon. The intervention will take place during the isolation phase and consists of an adapted physical activity (APA) program defined at inclusion, integrating supervised sessions with an APA teacher, as well as autonomous sessions. The program is individualized according to age, aerobic capacity, and PA preferences. Sessions are also tailored to the biological, psychological, and social parameters of patients. The total duration of the intervention is 3 months. To date, no PA studies have been performed in patients under 21 years of age requiring aGCSH during the sterile isolation phase. EVAADE will therefore be the first study in this population to offer an innovative procedure with a connected device.

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.
