Assessment
Primary outcomes	To investigate the predictors obtained at baseline and affecting the sustained virologic response (SVR) rate/occurrence of adverse drug reactions at follow-up Week 12
Key secondary outcomes	Effects of HCV NS5B mutations as viral factors on virologic response 2) Rate of emergence of drug-resistant variants 3) Presence or absence of a reversal of liver fibrosis 4) Presence or absence of an improvement in AFP levels 5) Effects of glucose/lipid-related factors on treatment response 6) Incidence of AEs
