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 15 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.

The investigators want to study if lower doses of chemotherapy will help babies with SCID to achieve good immunity with less short and long-term risks of complications after transplantation. This trial identifies babies with types of immune deficiencies that are most likely to succeed with this approach and offers them transplant early in life before they get severe infections or later if their infections are under control. It includes only patients receiving unrelated or mismatched related donor transplants. The study will test if patients receiving transplant using either a low dose busulfan or a medium dose busulfan will have immune recovery of both T and B cells, measured by the ability to respond to immunizations after transplant. The exact regimen depends on the subtype of SCID the patient has. Donors used for transplant must be unrelated or half-matched related (haploidentical) donors, and peripheral blood stem cells must be used. To minimize the chance of graft-versus-host disease (GVHD), the stem cells will have most, but not all, of the T cells removed, using a newer, experimental approach of a well-established technology. Once the stem cell transplant is completed, patients will be followed for 3 years. Approximately 9-18 months after the transplant, vaccinations will be administered, and a blood test measuring whether your child's body has responded to the vaccine will be collected.

SCID-X1 is a genetic disorder of blood cells caused by DNA changes in a gene that is required for the normal development of the human immune system. The purpose of this study is to determine if a new method, called lentiviral gene transfer, can be used to treat SCID-X1. This method involves transferring a normal copy of the common gamma chain gene into the participant's bone marrow stem cells. The investigators want to determine if the procedure is safe, whether it can be done according to the methods they have developed, and whether the procedure will provide a normal immune system for the patient. It is hoped that this type of gene transfer may offer a new way to treat children with SCID-X1 that do not have a brother or sister who can be used as a donor for stem cell transplantation.
open to all eligible people
This study is a prospective evaluation of children with Severe Combined Immune Deficiency (SCID) who are treated under a variety of protocols used by participating institutions. In order to determine the patient, recipient and transplant-related variables that are most important in determining outcome, study investigators will uniformly collect pre-, post- and peri-transplant (or other treatment) information on all children enrolled into this study. Children will be divided into three strata: - Stratum A: Typical SCID with virtual absence of autologous T cells and poor T cell function - Stratum B: Atypical SCID (leaky SCID, Omenn syndrome and reticular dysgenesis with limited T cell diversity or number and reduced function), and - Stratum C: ADA deficient SCID and XSCID patients receiving alternative therapy including PEG-ADA ERT or gene therapy. Each Group/Cohort Stratum will be analyzed separately.

People with Primary Immune Deficiency (PID) may develop severe, life-threatening infections as a result of inherited defects in the genes that normally instruct blood-forming cells to develop and to fight infections. PID diseases include Severe Combined Immune Deficiency (SCID), leaky SCID, Omenn syndrome (OS), and Reticular Dysgenesis (RD). PIDs may be treated by transplantation of bone marrow stem cells from a healthy person or, in some cases, by enzyme replacement or by gene therapy. Patients with SCID were among the first to receive bone marrow stem cell (also called hematopoietic cells) transplantation (HCT) more than 40 years ago, and HCT is the standard treatment today for this group of diseases. Since PID diseases are rare, there are not enough patients at any single center to determine the full range of causes, natural history, or best methods of treatment. For this research study many PID centers across North America have organized into the Primary Immune Deficiency Treatment Consortium (PIDTC) to pool their experience and study PIDs together. Researchers will collect information on your general health, psychological and developmental health, and the current status of your immune system to help better define future approaches to PID treatments.

Phase I/II Trial of Lentiviral Gene Transfer for SCID-X1 With Low Dose Targeted Busulfan Conditioning
open to eligible males ages up to 5 years
This is a phase I/II open label multi-center study in which patients will receive low dose targeted busulfan followed by infusion of autologous CD34+ selected bone marrow or mobilized peripheral blood cells transduced with the G2SCID vector. Subjects will be enrolled over 3 years and be followed for 2 years post-infusion on this protocol, then followed long-term on a separate long-term follow-up protocol. Enrollment of subjects will be agreed upon by representatives of both sites. Data will be collected uniformly from both sites through an electronic capture system and key laboratory studies will be centralized. Harvest, cellular manufacturing and infusion will occur at each site using the same SOPs. Key aspects of cellular product characterization will be centralized

This is a single-arm, open label, Phase 1 study to assess the safety and tolerability of CD34+CD90+ hematopoietic stem cell (HSC) allografts infused into patients with SCID who are conditioned for transplantation with AMG 191, an antibody that targets CD117 present on endogenous HSC. The target dose of CD34+CD90+ HSC will be >1 x 106 cells/kg and the optimal conditioning dose of AMG 191 will be determined during dose escalation.
An Observational LTFU Study for Patients Previously Treated With Autologous ex Vivo Gene Therapy for ADA-SCID
Sorry, accepting new patients by invitation only
This observational long-term follow-up study is designed to collect safety and efficacy data from ADA-SCID patients previously treated with autologous ex vivo gene therapy products based on the EFS-ADA LV encoding for human adenosine deaminase (ADA) gene (EFS-ADA LV), as part of the OTL-101 clinical development program. No investigational medicinal product will be administered to these patients as part of the OTL-101-6 study.
Gene Transfer for Severe Combined Immunodeficiency, X-linked (SCID-X1) Using a Self-inactivating (SIN) Gammaretroviral Vector
Sorry, in progress, not accepting new patients
Researchers are working on ways to treat SCID patients who don't have a matched brother or sister. One of the goals is to avoid the problems that happen with stem cell transplant from parents and unrelated people, such as repeat transplants, incomplete cure of the immune system, exposure to chemotherapy, and graft versus host disease. The idea behind gene transfer is to replace the broken gene by putting a piece of genetic material (DNA) that has the normal gene into the child's cells. Gene transfer can only be done if we know which gene is missing or broken in the patient. For SCID-X1, gene transfer has been done in the laboratory and in two previous clinical trials by inserting the normal gene into stem cells from bone marrow. The bone marrow is the "factory" inside the bones that creates blood and immune cells. So fixing the gene in the bone marrow stem cells should fix the immune problem, without giving chemotherapy and without risk of graft versus host disease, because the child's own cells are used, rather than another person's. Out of the 20 subjects enrolled in the two previous trials, 18 are alive with better immune systems after gene transfer. Two of the surviving subjects received gene corrected cells over 10 years ago. Gene transfer is still research for two reasons. One is that not enough children have been studied to tell if the procedure is consistently successful. Of the 20 children enrolled in the previous two trials, one child did not have correction of the immune system, and died of complications after undergoing stem cell transplant. The second important reason why gene transfer is research is that we are still learning about the side effects of gene transfer and how to do gene transfer safely. In the last two trials, 5 children have experienced a serious side effect. These children developed leukemia related to the gene transfer itself. Leukemia is a cancer of the white blood cells, a condition where a few white blood cells grow out of control. Of these children, 4 of the 5 have received chemotherapy (medication to treat cancer) and are currently in remission (no leukemia can be found by sensitive testing), whereas one died of gene transfer-related leukemia.
