Brief Summary

Severe combined immune deficiency (SCID) may result from inherited deficiency of the enzyme adenosine deaminase (ADA). Children with ADA-deficient SCID often die from infections in infancy, unless tre...

Detailed Description

The proposed study population is affected with adenosine deaminase-deficient severe combined immune deficiency (ADA-SCID), an autosomal recessive congenital immune deficiency. The basis of the propose...

Eligibility Criteria

Inclusion

  • Children \> 1.0 months of age with a diagnosis of ADA-deficient SCID based on:
  • Confirmed absence (\<3% of normal levels) of ADA enzymatic activity in peripheral blood or (for neonates) umbilical cord erythrocytes and/or leukocytes, or in cultured fetal cells derived from either chorionic villus biopsy or amniocentesis, prior to institution of enzyme replacement therapy.
  • AND
  • Evidence of severe combined immunodeficiency based on either:
  • Family history of first order relative with ADA deficiency and clinical and laboratory evidence of severe immunologic deficiency,
  • OR
  • Evidence of severe immunologic deficiency in subject based on lymphopenia (absolute lymphocyte count \<200) or severely decreased T lymphocyte blastogenic responses to phytohemagglutinin (deltaCPM\<5,000), prior to institution of immune restorative therapy.
  • OR
  • Fulfillment of criterion:
  • A in addition to evidence of genetic mutations affecting the ADA gene as determined by a CLIA certified laboratory and clinical evidence of combined immunodeficiency based on lymphopenia (absolute lymphocyte counts \<2SD of age-matched control values) and hypogammaglobulinemia (\<2SD of age-matched control values) or lack of specific antibody response to vaccination. In addition, for patients to be eligible under this criterion, they must present with a clinical history indicating life-threatening illness characterized by increased frequency and/or severity of infections resulting in hospitalization and/or the administration of intravenous antibiotics, for bacterial or opportunistic infection.
  • Ineligible for allogeneic (matched sibling) bone marrow transplantation (BMT):
  • Absence of a medically eligible HLA-identical sibling with normal immune function who may serve as an allogeneic bone marrow donor.
  • Written informed consent according to guidelines of the Institutional Review Board (IRB) at the University of California Los Angeles (UCLA).
  • This study is also open to delayed/late onset ADA-deficient patients who fulfill the criteria 1, 2.A, and 3 and who are not receiving PEG-ADA treatment after being invited to discuss all alternative treatment options with a physician not connected with the protocol.

Exclusion

  • Age less than 1 month
  • Hematologic
  • a. Anemia (hemoglobin \<10.5 mg/dl at \<2 years of age, or \< 11.5 at \>2 years of age,with normal serum iron studies). b. Neutropenia i. absolute granulocyte count \<500/mm3 or ii. absolute granulocyte count 500-999/mm3 (1 month - 1 year of age) or 500-1499/mm3 (\> 1 year of age)\] and bone marrow aspirate and biopsy showing myelodysplasia or other gross abnormality. c. Thrombocytopenia (platelet count 150,000/mm3, at any age). d. PT or PTT \>2X normal. e. Cytogenetic abnormalities on peripheral blood, or on cells collected by amniocentesis, if diagnosed in utero.
  • Infectious
  • a. Evidence of active opportunistic infection or infection with HIV-1, hepatitis B, CMV or parvovirus B 19 by DNA PCR at time of assessment.
  • Pulmonary
  • Resting O2 saturation by pulse oximetry \<95%.
  • Chest x-ray indicating active or progressive pulmonary disease.
  • Cardiac
  • Abnormal electrocardiogram (EKG) indicating cardiac pathology.
  • Uncorrected congenital cardiac malformation.
  • Active cardiac disease, including clinical evidence of congestive heart failure,cyanosis, hypotension.
  • Neurologic
  • Significant neurologic abnormality by examination.
  • Uncontrolled seizure disorder.
  • Renal
  • Renal insufficiency: serum creatinine \> or = 1.2 mg/dl, or \> or = 3+ proteinuria.
  • Abnormal serum sodium, potassium, calcium, magnesium, phosphate at grade III or IV by Division of AIDS Toxicity Scale.
  • Hepatic/GI:
  • Serum transaminases \> 5X normal.
  • Serum bilirubin \> 3.0 mg/dl.
  • Serum glucose \> 250mg/dl.
  • Intractable severe diarrhea.
  • Oncologic (see below\*)
  • Evidence of active malignant disease other than dermatofibrosarcoma protuberans (DFSP)
  • Evidence of DFSP expected to require anti-neoplastic therapy within the 5 years following the infusion of genetically corrected cells
  • Evidence of DFSP expected to be life limiting within the 5 years following the infusion of genetically corrected cells
  • Known sensitivity to Busulfan
  • General
  • Expected survival \<6 months.
  • Pregnant.
  • Major congenital anomaly.
  • Medically eligible HLA-matched sibling.
  • Other conditions which in the opinion of the P.I. or co-investigators, contra-indicate infusion of transduced cells or indicate patient's inability to follow protocol.
