Hepatitis C Virus InfectionThe primary objective of this study is to evaluate the efficacy, safety and tolerability of treatment with sofosbuvir/velpatasvir (Epclusa®; SOF/VEL) with ribavirin (RBV) for 24 weeks in adults with chronic hepatitis C virus (HCV) infection who participated in a prior Gilead sponsored study and did not achieve sustained virologic response (SVR).

Safety and Efficacy of Ledipasvir/Sofosbuvir Fixed Dose Combination +/- Ribavirin in Adolescents...
Hepatitis C Virus InfectionThe primary objective of the PK Lead-in Phase of the study is to evaluate the steady state pharmacokinetics (PK) and confirm the dose of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) in hepatitis C virus (HCV)-infected pediatric participants. The PK Lead-in Phase will also evaluate the safety, tolerability, and antiviral activity of 10 days of dosing of LDV/SOF FDC in HCV-infected pediatric participants. The Treatment Phase will be initiated by age cohort after confirmation of age-appropriate LDV/SOF FDC dosage levels. Participants from the PK Lead-in Phase will immediately rollover into the Treatment Phase with no interruption of study drug administration. The primary objective of the Treatment Phase is to evaluate the antiviral efficacy, safety, and tolerability of LDV/SOF FDC +/- ribavirin (RBV) for 12 or 24 weeks in pediatric participants with HCV. During screening, participants will receive placebo to match LDV/SOF FDC to assess ability to swallow tablets.

Safety and Pharmacokinetics of MK-7680 in Participants With Hepatitis C (MK-7680-003)
Hepatitis CThis is a two-part dose-finding trial of MK-7680 in participants with Hepatitis C Virus (HCV) infection of genotype (GT)1 (Part I) and GT3 (Part 2). The primary hypothesis is that daily administration of a safe and well tolerated dose of MK-7680 will produce a decrease in HCV viral load.

Chronic HCV InfectionThis study will evaluate ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) plus ribavirin (RBV) in participants with advanced liver disease or posttransplant and chronic genotype 1 or 4 hepatitis C virus (HCV) infection. Cohort A: decompensated cirrhosis (advanced liver disease), no prior liver transplant; Cohort B: post-liver transplant, with or without cirrhosis; Group assignment within cohorts is based on severity of liver impairment at screening (Child-Pugh-Turcotte (CPT) score for participants with cirrhosis; fibrosis; or presence of disease for fibrosing cholestatic hepatitis (FCH) groups) Randomization is 1:1 within groups to 12 or 24 weeks of LDV/SOF+RBV treatment.
