| Main Objective: The main objective of this trial is to assess the therapeutic efficacy of a hematopoietic gene therapy procedure with an orphan drug consisting of a lentiviral vector carrying the FANCA gene in patients with Fanconi anemia subtype A (complementation group A, FA-A).;Secondary Objective: Not applicable;Primary end point(s): • Level of phenotypic correction of hematopoietic cells after the infusion of autologous CD34+ cells transduced with the therapeutic lentiviral vector in patients with Fanconi anemia subtype A • Level of engraftment of gene-corrected hematopoietic cells after the infusion of autologous CD34+ cells transduced with the therapeutic lentiviral vector in patients with Fanconi anemia subtype A • Clinical response (prevention or rescue of bone marrow failure (BMF)) after the infusion of autologous CD34+ cells transduced with the therapeutic lentiviral vector in patients with Fanconi anemia subtype A • Ongoing evaluation of the short- and long-term safety of the infusion of autologous CD34+ cells transduced with the therapeutic lentiviral vector in patients with Fanconi anemia subtype A;Timepoint(s) of evaluation of this end point: Up to 3 years after infusion | — |
