| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The purpose of this study is to estimate efficacy, as determined by the proportion of subjects with SVR12, defined as HCV RNA < LOQ at posttreatment
 Week 12, for subjects who are prior null or partial responders
 to P/R or who are treatment-naive.
 |  
| Stimare l’efficacia, determinata dalla proporzione di soggetti con SVR12 , definita come HCV RNA < LOQ alla Settimana 12 post trattamento, per i soggetti che non hanno risposto o hanno risposto in modo parziale a precedente terapia con P/R o naive al trattamento. |  | 
| E.2.2 | Secondary objectives of the trial | 
| • Proportion of treated subjects with SVR12, defined as HCV RNA < LOQ at post-treatment Week 12, for subjects who are intolerant or ineligible
 to P/R;
 • On treatment safety, as measured by frequency of SAEs and
 discontinuations due to AEs through the end of treatment plus 7 days;
 |  
| • Proporzione di soggetti trattati con SVR12, definita come RNA < LOQ alla Settimana 12 post trattamento per i soggetti che sono Intolleranti o Ineleggibili a P/R; • Sicurezza durante il trattamento, misurata dalla frequenza di Eventi Avversi Seri (SAEs) e dalle interruzioni dovute ad Eventi Avversi (AEs) fino alla fine del trattamento più 7 giorni.

 a history or presence of ascites, bleeding varices, or hepatic
 encephalopathy;
 • Diagnosed or suspected hepatocellular carcinoma or other malignancies;
 • Uncontrolled diabetes or hypertension;
 |  
| • Precedente esposizione a qualsiasi HCV DAA; • Evidenza di  condizioni mediche che favoriscano malattia epatica cronica diversa dall’ HCV;
 • Evidenza di malattia epatica scompensata incluso, ma non limitato a,  storia  o presenza di ascite, varici sanguinanti  o encefalopatia epatica;
 • Diagnosi o sospetto di Carcinoma epatocellulare o altri tumori;
 • Diabete non controllato o ipertensione
