Trial Information

This study is the first in-human clinical trial to explore the safety, tolerability, and clinical efficacy of ex vivo gene therapy (autologous CD34+ cells transduced with a lentiviral vector containing the human SGSH gene) in MPSIIIA patients.

This study aims to recruit 3 to 5 patients with MPS IIIA who satisfy the inclusion and exclusion criteria and provide full consent, between 3 months and 24 months of age. The investigational medicinal product (IMP) will be a cell-based gene therapy that uses genetically modified autologous CD34+ haematopoietic stem cells transduced with a lentiviral vector containing the human SGSH gene. Patients will be followed up for a minimum of 3 years after gene therapy.
