Gene Therapy for X-linked Chronic Granulomatous Disease (CGD) in Children
Overview
The aim of the study is to evaluate the side effects and risks after infusion of retroviral gene corrected autologous CD34+ cells of the peripheral blood of chemotherapy conditioned (busulphan) children with chronic granulomatous disease (CGD). Also gene corrected and functional active granulocytes in the peripheral blood and the engraftment in the bone marrow of the patients will be monitored an documented.
