Title: A Phase 3, Multicenter, Randomized, Open-Label Study to Compare the Efficacy and Safety of Sofosbuvir/GS-5816 Fixed Dose Combination for 12 Weeks With Sofosbuvir and Ribavirin for 12 Weeks in Subjects With Chronic Genotype 2 HCV Infection
Brief Summary: The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks compared to treatment with sofosbuvir (SOF) plus ribavirin (RBV) for 12 weeks in participants with chronic genotype 2 hepatitis C virus (HCV) infection.
