NCT03814408

Brief Summary

The objective of this study is to assess the therapeutic safety and preliminary efficacy of a hematopoietic cell-based gene therapy consisting of autologous CD34+ enriched cells transduced with a lentiviral vector carrying the FANCA gene in subjects with Fanconi anemia subtype A (FA-A).

Eligibility Criteria

Age1 Year - 12 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Fanconi anemia, as diagnosed by chromosomal fragility assay of cultured T-lymphocytes in the presence of DEB or a similar DNA-crosslinking agent.
  • Subjects of Fanconi Anemia complementation group A.
  • Minimum age: 1 year and a minimum of 8 kg.
  • Maximum age: 12 years.
  • At least one of the following hematologic parameters below lower limits of normal:
  • Hemoglobin
  • Absolute neutrophils
  • Platelets
  • At least 30 CD34+ cells/μL are determined in one BM aspiration within 3 months prior to initiation of CD34+ cell collection.
  • If the number of C34+ cells/ μL in BM is in the range of 10-29, PB parameters should meet two of the three following criteria:
  • Hemoglobin: ≥11g/dL
  • Neutrophils: ≥900 cells/μL
  • Platelets: ≥60,000 cells/μL
  • Provide informed consent in accordance with current legislation.
  • Women of childbearing age must have a negative urine pregnancy test at the baseline visit and accept the use of an effective contraception method during participation in the trial.

You may not qualify if:

  • Subjects with an available and medically eligible human leukocyte antigen (HLA)-identical sibling donor.
  • Evidence of myelodysplastic syndrome or leukemia, or cytogenetic abnormalities predictive of these conditions in BM aspirate analysis. This assessment should be made by valid studies conducted within the 3 months before the subject commences the stem cell mobilization/collection procedures of the clinical trial.
  • Subjects with somatic mosaicism associated with stable or improved counts in all PB cell lineages. (If T-lymphocyte chromosomal fragility analysis indicates potential mosaicism, a medically significant decrease in at least one blood lineage over time must be documented to enable eligibility).
  • Lansky performance status ≤60%.
  • Any concomitant disease or condition that, in the opinion of the Principal Investigator, renders the subject unfit to participate in the study.
  • Pre-existing sensory or motor impairment ≥grade 2 according to the NCI CTCAE v5.0 criteria.
  • Pregnant or breastfeeding women.
  • Hepatic dysfunction as defined by either:
  • Bilirubin \>3.0 × upper limit of normal (ULN) or
  • Alanine aminotransferase (ALT) \> 5.0 × ULN or
  • Aspartate aminotransferase (AST) \> 5.0 × ULN
  • Renal dysfunction requiring either hemodialysis or peritoneal dialysis.
  • Pulmonary dysfunction as defined by either:
  • Need for supplemental oxygen during the prior 2 weeks in absence of acute infection.
  • Oxygen saturation by pulse oximetry \<90%.
  • +2 more criteria
