E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
i) To determine the safety of peripheral blood stem cell (PBSC) mobilization with Mozobil alone or with G-CSF +Mozobil in adults with b thalassemia major ii) To collect with Mozobil or Mozobil+G-CSF a total of at least 6X106CD34+ cells/kg for subsequent clinical scale transduction with a beta-globin lentiviral vector, in a clinical beta-globin gene transfer trial. |
|
E.2.2 | Secondary objectives of the trial |
i) To determine the clonogenic capacity of cells mobilized by Mozobil alone- or by G-CSF + Mozobil, ii) To determine the cells’ ability to be transduced with a recombinant lentivirus vector for b-globin iii) To determine the transduced cells’ potential to engraft in a xenograft model.

E.5 End points |
E.5.1 | Primary end point(s) |
- the safety of Mozobil or Mozobil+G-CSF mobilization in splenectomized and non-splenectomized patients with b thalassemia major - the proportion of patients who will yield greater than or equal to 6X106 CD34+cells/kg by Mozobil alone - the proportion of patients who will yield cumulatively greater than or equal to 6X106 CD34+cells/kg by the combination of Mozobil+G-CSF and who had previously failed to reach the cell dose target either with G-CSF alone or Mozobil-alone - the number of apheresis days required to reach more than or equal to 6X106 CD34+cells/kg by Mozobil alone - the number of apheresis days required to cumulatively reach more than or equal to 6X106 CD34+cells/kg by the combination of Mozobil+G-CSF in patients who had previously failed to reach this cell dose target either by G-CSF or Mozobil.
Importantly, in patients previously mobilized with G-CSF alone (Thal-001 study) or with Mozobil alone (Thal-002 study) the comparison of paired samples from each patient will eliminate inter-patient variability in the analysis, as each patient will serve as his or her own control. This will allow conclusions to be drawn on the relative efficacy of the two mobilization schemes that would otherwise be difficult to draw from this number of patients. |
