This is a long-term safety and efficacy follow-up study for subjects with Fanconi Anaemia Subtype A who have been treated with ex vivo gene therapy on the FANCOLEN-I trial. After completion of the FANCOLEN-I study, eligible subjects will be followed for a total of 15 years post gene therapy treatment. No investigational drug product will be administered during this study.
This long-term follow-up protocol will evaluate the long term safety and efficacy of the infusion of autologous CD34+ cells transduced with lentiviral vector (LV) carrying the FANCA gene.
