Clinical Trial Summary

This 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12)	SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) at 12 weeks after stopping study treatment.	Posttreatment Week 12
Primary	Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event		Up to 24 weeks
Secondary	Percentage of Participants With SVR 2 Weeks After Discontinuation of Therapy (SVR2)	SVR2 was defined as HCV RNA < LLOQ at 2 weeks after stopping study treatment.	Posttreatment Week 2
Secondary	Percentage of Participants With SVR 4 Weeks After Discontinuation of Therapy (SVR4)	SVR4 was defined as HCV RNA < LLOQ at 4 weeks after stopping study treatment.	Posttreatment Week 4
Secondary	Percentage of Participants With SVR 8 Weeks After Discontinuation of Therapy (SVR8)	SVR8 was defined as HCV RNA < LLOQ at 8 weeks after stopping study treatment.	Posttreatment Week 8
Secondary	Percentage of Participants With SVR 24 Weeks After Discontinuation of Therapy (SVR24)	SVR24 was defined as HCV RNA < LLOQ at 24 weeks after stopping study treatment.	Posttreatment Week 24
Secondary	Percentage of Participants With Virologic Failure	Virologic failure was defined as: On-treatment virologic failure: Breakthrough (confirmed HCV RNA = LLOQ after having previously had HCV RNA < LLOQ on 2 consecutive measurements while on treatment), or; Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment); Virologic relapse: Confirmed HCV RNA = LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit.	Up to Posttreatment Week 24
Secondary	Percentage of Participants With Posttransplant Virologic Response (pTVR) at Posttransplant Week 12	pTVR was defined as HCV RNA < LLOQ at Week 12 after transplant.	Posttransplant Week 12
Secondary	Percentage of Participants With HCV RNA < LLOQ at Week 1		Week 1

Secondary	Percentage of Participants With a Decrease, No Change, or Increase Between Baseline and Posttreatment Week 4 in MELD Score	Model for End-Stage Liver Disease (MELD) scores are used to assess prognosis and suitability for liver transplantation. Scores can range from 6 to 40; higher scores/increased scores indicate greater severity of disease.	Baseline to Posttreatment Week 4
Secondary	Percentage of Participants With a Decrease, No Change, or Increase Between Baseline and Posttreatment Week 4 in CPT Score	CPT scores grade the severity of cirrhosis and are used to determine the need for liver transplantation. Scores can range from 5 to 15 (maximum score for entry into the study was 12); higher scores/increased scores indicate greater severity of disease. Groups are arranged by cohort, then by duration of treatment, then by CPT class at baseline.	Baseline to Posttreatment Week 4
