| Main Objective: 1. Treatment of SCID-X1 patients by somatic gene therapy when HLA-matched family or unrelated bone marrow donors are unavailable. 2. Successful ex vivo transduction of CD34+ haematopoietic cells from SCID-X1 patients by ex vivo gammaretrovirus-mediated gene transfer. 3. Evaluation of immunological and functional reconstitution in progeny of engrafted cells. 4. Longitudinal evaluation of clinical effect in terms of augmented immunity. 5. Evaluation of the functional performance of novel SIN gammaretroviral configuration. 6. Evaluation of the molecular characteristics of vector integration. 7. Evaluation of safety. ;Secondary Objective: ;Primary end point(s): Immunological reconstitution | — |
