This study aims to evaluate the efficacy and safety of DCV plus sofosbuvir (SOF) with or without ribavirin (RBV) for treatment of Egyptian participants infected with HCV GT4.

Egyptian participants infected with HCV GT4 were classified into two groups: group 1 (easy to treat) was treated with a dual therapy of SOF/DCV daily for 12 weeks and group 2 (difficult to treat) was treated with a triple therapy of SOF/DCV/RBV daily for 12 weeks.

SOF dose was 400 mg/day given orally DCV was given in a dose of 60 mg/day, orally. RBV was given as oral tablets in the morning and in the evening based on patient's weight and tolerability (starting dose 600 mg/day to reach 1200 mg/day.
