ADA Deficiency clinical trials at UC Health
5 in progress, 3 open to new patients

  • EZN-2279 in Patients With ADA-SCID

    open to all eligible people

    The purpose of this study is to evaluate the safety, efficacy, and pharmacokinetics of EZN-2279 in patients with ADA-deficient combined immunodeficiency currently being treated with Adagen.

  • Natural History Study of SCID Disorders

    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.

  • Patients Treated for SCID (1968-Present)

    open to all eligible people

    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.

  • Autologous Cryopreserved CD34+ Hematopoietic Cells Transduced With EFS-ADA Lentivirus for ADA SCID

    Sorry, in progress, not accepting new patients

    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 LV encoding for the human ADA gene) administered to ADA-SCID subjects between the ages of 30 days and 17 years of age, who are not eligible for an HLA-matched sibling/family donor and meeting the inclusion/exclusion criteria. The OTL-101 product will be infused after a minimal interval of at least 24 hours following the completion of reduced intensity conditioning. For subjects who have successfully received the OTL-101 product, PEG-ADA ERT will be discontinued at Day+30 (+/-3) 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.

  • Autologous Transplant of EFS-ADA Modified Bone Marrow Cells for ADA-Deficient Severe Combined Immunodeficiency (SCID)

    Sorry, in progress, not accepting new patients

    In this current study, the investigators will determine whether using a lentiviral vector (based on HIV-1) will be more effective and safer at gene transfer to hematopoietic stem cells compared to previous gene transfer vectors based on murine (mouse) retroviruses for ADA-deficient SCID. The level of gene transfer in blood cells and immune function will be measured as endpoints.
