NCT01938625
The purpose of the study is to evaluate effect of steady-state (when the amount of drug administered (in a given time period is equal to the amount of drug eliminated in that same period) of simeprevir and daclatasvir on the steady-state pharmacokinetics (what a medication does to the body) of cyclosporine (applicable to Part 1 only) and tacrolimus when administered as a combinational regimen in post-orthotopic liver transplantation (OLT) participants with recurrent hepatitis C virus (HCV) genotype 1b infection and effectiveness of a 24-week treatment regimen containing simeprevir, daclatasvir, and ribavirin (RBV) with respect to the proportion of HCV genotype 1b infected post-OLT participants achieving sustained virologic response 12 weeks after end of treatment.
NCT01984294
This study will evaluate the antiviral efficacy of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) plus ribavirin (RBV) or LDV/SOF plus GS-9669 in treatment-naive or treatment-experienced participants with chronic genotype 1 hepatitis C virus (HCV) infection. A total of 90 participants are planned to be enrolled in the study for 8 weeks of treatment, approximately 60 having had prior treatment with a regimen containing pegylated interferon (PEG) and RBV for ≥ 12 weeks. Randomization will be stratified by treatment-naive versus treatment-experienced and by HCV genotype (1a versus 1b).
NCT02010255
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.
NCT03316313

NCT02081079
This study is to evaluate the efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) in participants with chronic genotype 4 or 5 hepatitis C virus (HCV) infection as measured by the proportion of subjects with sustained virologic response (SVR12), defined as HCV RNA \< lower limit of quantification (LLOQ) 12 weeks after discontinuation of therapy.
NCT02690792
One-third of the US population has non-alcoholic fatty liver disease (NAFLD) due to obesity and \~8 million of these individuals have a progressive form of the disease, non-alcoholic steatohepatitis (NASH). Currently, there are no noninvasive ways to determine which individuals with NAFLD will develop NASH. This is of medical importance since NASH can be a prelude to the development of end-stage liver disease. The study of NAFLD has been limited by several factors, including the difficulties associated with studying liver metabolism in vivo in humans. Our group has pioneered new methods that use nuclear magnetic resonance (NMR) to measure intermediary hepatic metabolism in humans with a goal of directly studying the pathophysiology of bland steatosis and NASH. In this study, these noninvasive methods will be used to characterize and compare the metabolic alterations that accompany bland steatosis and NASH and test the hypothesis that detects if hepatic mitochondrial metabolism contribute to both disorders. Such characterization is fundamental to establishing a rational approach to the prevention and treatment of NAFLD and may provide simple, non-invasive methods to differentiate benign and progressive forms of NAFLD. This proposal will be addressed via separate isotopic studies occurring at different time points during a prolonged fast. In subjects with NAFLD, these studies will be carried out before and after treatment with Vitamin E or placebo. Healthy subjects will participate in initial baseline studies only without Vitamin E or placebo intervention. The study is designed to harness the physiologic changes that occur with short- and long-term fasting to provide a rapid and cost-effective method to accomplish the aims of the application.
NCT02472886
The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) with or without ribavirin (RBV) in adults with chronic hepatitis C virus (HCV) infection.
NCT01851330
This study is to evaluate the safety, tolerability, and antiviral efficacy of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) with or without ribavirin (RBV) administered for 8 or 12 weeks in treatment-naive participants with chronic genotype 1 HCV infection.
NCT02202980
This study will evaluate the antiviral efficacy, safety, and tolerability of combination therapy with oral regimens for the treatment of chronic hepatitis C virus (HCV) infection.
