E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To explore the safety of IBU, G-CSF and Plerixafor when administered as a stem cell mobilization regimen in patients affected by X-CGD.
2. To explore the effect of IBU, G-CSF and Plerixafor in mobilizing CD34+ cells thus allowing the collection of a number of HSPC deemed sufficient for ex vivo gene therapy in patients affected by X-CGD.
|
1. Esplorare la sicurezza di Ibuprofene, G-CSF e Plerixafor, somministrati come regime mobilizzante in pazienti affetti da X-CGD.
2. Esplorare l’effetto di Ibuprofene, G-CSF e Plerixafor nella mobilizzazione delle cellule CD34+, permettendo una raccolta di cellule ematopoietiche staminali progenitrici che possa essere ritenuta adeguata per terapia genica ex vivo in pazienti affetti da X-CGD.
|
|
E.2.2 | Secondary objectives of the trial |
1. To explore the effect of Ibuprofen in mobilizing CD34+ cells in the PB.
2. To explore the in vitro efficacy of a lentiviral vector encoding for a corrective cDNA of the human gp91phox gene in transducing CD34+ cells obtained by the XCGD-MOBI protocol and correcting the func-tional defects in the differentiated myeloid progeny.
3. To functionally characterize the properties of IBU, G-CSF and Plerixafor mobilized CD34+ cells from X-CGD patients
|
1. Esplorare l’effetto della mobilizzazione delle cellule CD34+ in sangue periferico con Ibuprofene.
2. Esplorare l'efficacia in vitro di trasduzione tramite un vettore lentivirale contente il gene della gp91phox umana nelle cellule CD34+ ottenute da questo regime di mobilizzazione e correggere i difetti funzionali nella progenie mieloide differenziata.
3. Caratterizzare funzionalmente le proprietà delle cellule CD34+ mobilizzate con IBU, G-CSF e Plerixafor da pazienti X-CGD.
