The primary objective of this trial is determination of hepatic functional improvement as measured by the HepQuant (HQ) test during and after Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV). Standard laboratory tests, clinical models (MELD, CTP), liver biopsy, hepatic venous pressure gradient (HVPG), and other imaging tests are insensitive, invasive, or nonspecific.
