Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase I/II study to evaluate the safety and efficacy of Hematopoietic Stem Cell genetherapy for the Wiskott-Aldrich Syndrome.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
