  Purpose

Adenosine deaminase deficiency is an inherited disorder that results in severe abnormalities of the immune system and leaves children unable to fight infection. This trial aims to treat adenosine deaminase deficiency patients using gene therapy.


Condition Intervention Phase
Adenosine Deaminase Deficiency
 Biological: Intravenous infusion of transduced cells
 Phase 1
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase I Gene Therapy Protocol for Adenosine Deaminase Deficiency

Criteria

Inclusion Criteria:

  1. Patients who lack a human leukocyte antigen (HLA)-genotypically identical bone marrow donor OR phenotypically matched family or unrelated donor AND who show incomplete immune reconstitution on Polyethylene glycol-modified adenosine deaminase (PEG-ADA) enzyme replacement therapy (defined by absolute CD4+ count <300 cell/mm3 and who remain on immunoglobulin replacement therapy)
  2. Diagnosis of ADA-SCID (Severe combined immunodeficiency (SCID) due to adenosine deaminase (ADA)confirmed by DNA sequencing OR by confirmed absence of <3% of ADA enzymatic activity in peripheral blood or (for neonates) in umbilical cord blood erythrocytes and/or leukocytes or in cultured fetal cells derived from either chorionic villus biopsy or amniocentesis, prior to institution of PEG-ADA replacement therapy
  3. Parental/guardian/patient signed informed consent
