Ledipasvir/Sofosbuvir Fixed-Dose Combination + Ribavirin in Subjects With Chronic HCV With Advanced Liver Disease or Post-Liver Transplant

Phase 2
Completed
Conditions
Chronic HCV Infection
Interventions
Drug: LDV/SOF
Registration Number
NCT01938430
Lead Sponsor
Gilead Sciences
Brief 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.

Percentage of Participants With a Decrease, No Change, or Increase Between Baseline and Posttreatment Week 4 in CPT ScoreBaseline to Posttreatment Week 4

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.

Percentage of Participants With a Decrease, No Change, or Increase Between Baseline and Posttreatment Week 4 in MELD ScoreBaseline to Posttreatment Week 4

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.
