| E.1.3 | Condition being studied is a rare disease | No | 
| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To determine if the administration of a combination of GS 7977 and ribavirin to post-OLT HCV subjects for 24 weeks can prevent post-transplant HCV re-infection as determined by a sustained post-transplant virological response (HCV RNA <LLoQ) at 12 weeks post-transplant |  
| L’obiettivo primario dello studio è valutare se la somministrazione della combinazione GS 7977 (Sovaldi®) e Ribavirina nell’immediato post-operatorio a pazienti sottoposti a trapianto per malattia epatica HCV-correlata può prevenire la reinfezione del graft definite come risposta virologica sostenuta (SVR) (HCV RNA <LLoQ) a 12 settimane post-trapianto |  | 
| E.2.2 | Secondary objectives of the trial | 
| •	Effect of treatment on HCV-related liver disease histology at 1-year •	To evaluate the HCV RNA viral kinetics during the initial treatment phase (2 weeks, 4 weeks, 8 weeks) and correlation with response rate
 Evaluate, from the perspective of the Italian NHS, the overall healthcare cost of the pre-emptive treatment with sofosbuvir and ribavirin of post- LT HCV patients during the observational period. The collectionof these data will allow to compare, in a descriptive way, these costs vs those of patients, with similar characteristics, treated according the current routine practice.
 
 |  
| •	Effetto del trattamento sul quadro istologico epatico ad 1 anno dal trapianto •	Cinetica di HCV RNA durante le fasi iniziali del trattamento e sua correlazione con il tasso di risposta e breaktrough
 •	Valutare i costi associati al trattamento dei pazienti nel periodo di osservazione nella prospettiva del Servizio Sanitario Nazionale. La rilevazione dei dati permetterà di confrontare, secondo una modalità descrittiva, i costi sostenuti per il trattamento pre-emptive con sofosbuvir/ribavirina rispetto ai costi di trattamento secondo l’attuale pratica clinica di pazienti con caratteristiche simili.
