This is a phase I/II study to evaluate the safety and efficacy of Hematopoietic Stem Cell genetherapy for the Wiskott-Aldrich Syndrome.
This clinical trial is an ex vivo gene therapy trial. The investigational product corresponds to autologous CD34+ cells transduced with a lentiviral vector harboring the human WASP gene.
