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 evaluating safety and efficacy of autologous hematopoietic stem cells genetically modified with GLOBE lentiviral vector encoding for the human beta-globin gene for the treatment of patients affected by transfusion dependent beta-thalassemia

Detailed Description

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

Both adults and pediatric patients will be treated with genetically modified autologous hematopoietic stem cells collected from mobilized peripheral blood (or bone marrow for patients \< 8 years in case mobilization will not be feasible) and transduced with GLOBE lentiviral vector encoding for the human beta-globin gene.

This study will enroll 10 patients allocated in 3 groups, according to age and conditioning regimen:

1. 3 adults (≥18 years) conditioned with treosulfan and thiotepa
2. 3 elderly children (8-17 years) conditioned with treosulfan and thiotepa
3. 4 younger children (3-7 years) conditioned with treosulfan and thiotepa Enrolment will start in adult patients. Pediatric patients will be included once evidence of preliminary safety and biological efficacy is shown in at least 2 adults.

Patients are included regardless of the beta globin gene mutation, provided an adequate cardiac, renal, hepatic and pulmonary function is demonstrated. Patients with severe iron overload are excluded as well as patients with active viral infections. Pediatric patients can be enrolled only in absence of a human leukocyte antigen (HLA)-identical sibling or a suitable 10/10 matched unrelated donor.

The treated patients will be followed for 2 years. After completion of the 2 years follow up, patients will be enrolled in a long term follow up study and followed up for at least other additional 6 years.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Adults

≥18 years (3 subjects) The ATIMP consists of autologous CD34+ cell enriched fraction containing hematopoietic stem cells (HSC) transduced with the GLOBE lentiviral vector encoding for the beta-globin gene re-suspended in their final formulation medium.

Dosage indications The target dose in the transduced product is 5x10(6) cells/Kg CD34+cells, with a minimum dose of 2x10(6)/Kg and a maximum dose of 20x10(6)/Kg, depending on the yield of cells.

The product will be injected intraosseously.
