Adenosine Deaminase Severe Combined Immune Deficiency

The aim of this study is to assess the safety and efficacy of autologous transplantation of hematopoietic stem cells (CD34+ cells) from mobilized peripheral blood (mPB) of ADA-deficient SCID infants and children following human ADA gene transfer by the EFS-ADA lentiviral vector. The level of gene transfer in blood cells and immune function will be measured as endpoints.

Gene Therapy for X Linked Severe Combined Immunodeficiency

Gene Therapy

A safety and efficacy clinical study of a lentiviral vector to transfer IL2RG complementary DNA to bone marrow stem cells in ten children with genetic diagnosed X-SCID(severe combined immune deficiency ).The ten children will be followed for 3-5 years and be evaluated by clinical characteristics, vector marking (vector copy number per cell) in blood and bone marrow cells, immune reconstitution vector insertion-site patterns and so on.

Lentiviral Gene Therapy for X-linked Severe Combined Immunodeficiency

Severe Combined ImmunodeficiencyX-Linked

Severe combined immunodeficiency disorder (SCID) is a heterogeneous group of inherited disorders characterized by a profound reduction or absence of T lymphocyte function, resulting in lack of both cellular and humoral immunity. SCID arises from a variety of molecular defects which affect lymphocyte development and function. The most common form of SCID is an X-linked form (SCID-X1), which accounts for 30-50% of all cases. SCID-X1 is caused by defects in the common cytokine receptor gamma chain, which was originally identified as a component of the high affinity interleukin-2 receptor (IL2RG). Allogeneic haematopoietic stem cell transplantation (HSCT), which replaces the patient's bone marrow with that of a healthy donor, is the only treatment that definitively restores the normal function of the bone marrow. HSCT is the first choice of treatment for patients with signs of bone marrow failure and a fully-matched related donor. However, patients without a fully-matched related donor have much worse overall outcomes from HSCT. This study will investigate whether patients with SCID-X1 without a fully matched related donor may benefit from gene therapy. To do this the investigators propose to perform a phase I/II clinical trial to evaluate the safety and efficacy (effect) of gene therapy for SCID-X1 patients using a lentivirus delivery system containing the IL2RG gene. Up to 5 eligible SCID-X1 patients will undergo mobilisation and harvest of their haematopoietic stem precursor cells (HPSCs). In the laboratory the disabled lentivirus will be used to insert a normal human IL2RG gene into the patient's harvested HPSCs. Patients will receive chemotherapy conditioning prior to cell infusion, in order to enhance grafting. The genetically corrected stem cells will then be re-infused into the patient. Patients will be followed up for 2 years. This trial will determine whether gene therapy for SCID-X1 using a lentiviral vector is safe, feasible and effective

Phase I/II Clinical Trial Stem Cell Gene Therapy in RAG1-Deficient SCID

Severe Combined Immunodeficiency Due to RAG1 Deficiency

This study is a prospective, non-randomized, open-label, two-centre phase I/II intervention study designed to treat children up to 24 months of age with RAG1-deficient SCID with an indication for allogeneic hematopoietic stem cell transplantation but lacking an HLA-matched donor. The study involves infusion of autologous CD34+ cells transduced with the pCCL.MND.coRAG1.wpre lentiviral vector (hereafter called RAG1 LV CD34+ cells) in five patients with RAG1-deficient SCID.

Autologous Gene Therapy for Artemis-Deficient SCID

Severe Combined Immunodeficiency

This study aims to determine if a new method can be used to treat Artemis-deficient Severe Combined Immunodeficiency (ART-SCID), a severe form of primary immunodeficiency caused by mutations in the DCLRE1C gene. This method involves transferring a normal copy of the DCLRE1C gene into stem cells of an affected patient. Participants will receive an infusion of stem cells transduced with a self-inactivating lentiviral vector that contains a normal copy of the DCLRE1C gene. Prior to the infusion they will receive sub-ablative, dose-targeted busulfan conditioning. The study will investigate if the procedure is safe, whether it can be done according to the methods described in the protocol, and whether the procedure will provide a normal immune system for the patient. A total of 25 patients will be enrolled at the University of California San Francisco in this single-site trial, and will be followed for 15 years post-infusion. It is hoped that this type of gene transfer may offer improved outcomes for ART-SCID patients who lack a brother or sister who can be used as a donor for stem cell transplantation or who have failed to develop a functioning immune system after a previous stem cell transplant.

Immune Disorder HSCT Protocol

Immune Deficiency DisordersSevere Combined Immunodeficiency12 more

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.
