59 In this phase 2 open-label study, patients with chronic HCV infection of any genotype (GT) listed for LT for hepatocellular carcinoma (HCC) received up to 48 weeks of SOF 400 mg/day and RBV 1000-1200 mg/day before LT. All patients had HCC within Milan criteria and well compensated cirrhosis (Child-Pugh-Turcotte score of ≤7). Post-LT immunosuppressive regimen was tacrolimus plus prednisone with or without mycophenolate mofetil. Induction was excluded Curry MP, et al. Abstract #213, AASLD 2013
