E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To explore the safety of Plerixafor administration to patients affected by transfusion dependent betathalassemia Efficacy 2. To explore the efficacy of Plerixafor in mobilizing CD34+ cells in patients affected by transfusion dependent beta-thalassemia |
Sicurezza espressa come valutazione dell’incidenza e della severita' degli eventi avversi (qualsiasi grado) insorti tra il giorno 0 e il giorno +30 dopo somministrazione del Plerixafor. Efficacia espressa come numero di cellule CD34+ per chilogrammo di peso corporeo raccolte (superiore a 5x10^6/kg in almeno 3 pazienti su 6). |
|
E.2.2 | Secondary objectives of the trial |
1. To explore the efficiency of transduction of Plerixafor mobilized CD34+ cells and Plerixafor primed BM cells from patients with beta-thalassemia using a lentiviral vector encoding for human beta globin 2. To evaluate yield of CD34+ cells harvest from BM following administration of Plerixafor (primed-BM). 3. To characterize Plerixafor mobilized CD34+ cells from thalassemic patients. |
1.esplorare l'efficienza di trasduzione di plerixafor nel mobilizzare cellule CD34 + e cellule BM inescate da plerixafor da pazienti affetti da beta-talassemia utilizzando una codifica lentivirale come vettore di beta globine umane 2.valutare la resa del raccolto di cellule CD34 + da BM dopo la somministrazione di plerixafor (primer-BM). 3. caratterizzare le cellule CD34 + cellule di pazienti talassemici mobilizzate con plerixafor |
