简要总结
The primary objective of this study is to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed-dose combination (FDC) for 8 weeks and of treatment with sofosbuvir/velpatasvir (SOF/VEL) FDC for 12 weeks in participants naive to direct-acting antivirals (DAA) with chronic genotype 3 hepatitis C virus (HCV) infection and cirrhosis.
