Clinical trial NCT02010255
Conditions: Chronic HCV Infection
Sponsor: Gilead Sciences
Start date: 2014-01-01; Completion date: 2015-08-01
Enrollment: 334 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

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.
