This is a pediatric open-label Phase 1 clinical trial and will include a safety evaluation and preliminary assessment of the efficacy of hematopoietic gene therapy consisting of autologous CD34+ enriched cells transduced with a lentiviral vector carrying the FANCA gene in subjects with FA-A. CD34+ cells will be transduced ex vivo with the therapeutic lentiviral vector and infused following transduction, without any prior conditioning. After transduction, product quality control evaluations will be carried out in aliquots of the transduced population. Investigational product will be infused via intravenous infusion with no upper or lower limit; a dose of ≥5 x 105 CD34+ cells/kg body weight will be considered optimal.~The active agent is a self-inactivating lentiviral vector carrying the therapeutic FANCA gene and the therapeutic product is subject's autologous HSCs that have been transduced with the lentiviral vector. The vector contains the functional FANCA gene.
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).
