This is a phase I/II study evaluating safety and efficacy of autologous hematopoietic stem and progenitor cells genetically modified with IDUA lentiviral vector encoding for the human α-L-iduronidase gene for the treatment of patients affected by Mucopolysaccharidosis Type I, Hurler variant
Pediatric patients with mucopolysaccharidosis type I will be treated with genetically modified autologous hematopoietic stem cells collected from mobilized peripheral blood (or bone marrow if mobilization is not feasible) and transduced with IDUA lentiviral vector encoding for the human α-L-iduronidase gene.
Patients will be followed for 8 years after gene therapy. After completing participation in this study, subjects will be offered enrollment into an approved long term follow-up (LTFU) study which will enable continued follow-up for up to 15 years post-treatment (per regulatory guidelines for follow up of patients treated with ATMPs).
