Inclusion criteria
Inclusion criteria: • Written informed consent • Transfusion-dependent beta-thalassemia (any genotype). Transfusion dependence is defined as receiving = 8 transfusions of blood per year over a minimum of 2 years. • Karnofsky Index or Lansky > 80% • Age = 3 years and 50% and forced expiratory volume in 1 sec (FEV1) and forced expiratory vital capacity (FVC) > 60% predicted (if non cooperative: pulse oximetry > 95 % in room air) ? Serum creatinine =65 years) no F.1.3.1 Number of subjects for this age range

| Main Objective: 1. To evaluate the safety and tolerability of autologous CD34+ cell enriched fraction that contains Hematopoietic Stem Cells (HSC) transduced with Lentiviral Vector (LV) encoding the beta-globin gene in pediatric and adult patients with transfusion dependent beta-thalassemia following a reduced toxicity conditioning regimen. 2. To evaluate the efficacy of autologous CD34+ cell enriched fraction that contains Hematopoietic Stem Cells (HSC) transduced with Lentiviral Vector (LV) encoding the beta-globin gene in pediatric and adult patients with transfusion dependent beta-thalassemia following a reduced toxicity conditioning regimen. ;Secondary Objective: NA;Primary end point(s): End point primario: 1) Overall survival E.5.1.1 Tempo/i di rilevazione di questo end point: • 2 years from gene therapy E.5.1 End point primario (ripetere se necessario): 2) Achievement of hematological engraftment defined as: • first day of neutrophil count >500/mm3 • platelets >20,000/mm3 on 3 consecutive blood counts = day +60 from gene therapy. E.5.1.1 Tempo/i di rilevazione di questo end point: • neutrophil count (0-24h) • platelets count = day +60 from gene therapy E.5.1 End point primario (ripetere se necessario): 3) Safety of the administration of autologous HSC transduced with LV-GLOBE measured as: • short-term tolerability; • absence of Replication Competent Lentivirus (RCL); • absence of abnormal clonal proliferation. E.5.1.1 Tempo/i di rilevazione di questo end point: • short-term tolerability (0-24 hours from gene therapy); • absence of Replication Competent Lentivirus (RCL) (0-24 months) • absence of abnormal clonal proliferation (0-24 months). E.5.1 End point primario (ripetere se necessario): 4) Short-term safety and tolerability of the different conditioning regimens. E.5.1.1 Tempo/i di rilevazione di questo end point: • from day -5 to day 100 after ATIMP Injection by clinical and laboratory surveillance E.5.1 End point primario (ripetere se necessario) | — |
