1. Achieve sustained virologic response (SVR) in patients infected with HCV genotype 1, cirrhosis, and early clinical decompensation using 12 weeks of Olysio/Sovaldi/Ribavirin (or known as: Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin (RBV). 2. Hepatic improvement during and after Simeprevir(SMV)/Sofosbuvir(SOF)/Ribavirin(RBV) treatment using a new test of liver function, HepQuant-SHUNT.
Chronic liver injury leads to the accumulation of proteins in the liver that form dense scars. Liver scar formation is typically a slow process that leads to major organ damage and loss of function over the course of many years. During scar formation the extracellular matrix in the liver changes. The type and quantity of extracellular collagen and other proteins change during tissue remodeling. Some of these changes can be detected by analyzing factors present in blood. Because of the lengthy time course, changes in the rate of liver scar formation and regression are very difficult measure; however, accurate measurements are needed in order to conduct trials of interventions aimed at preventing scar formation and/or promotion scar regression. Current methods have sub-optimal specificity and selectivity. The long term objective of the study is to identify serum proteins that can be used to accurately estimate rates of liver fibrosis progression and regression. The project focusses on a novel methodology that uses stable isotope labeling with deuterated water, D2O, to tag newly-synthesized proteins. Mass spectroscopy is used to identify individual proteins and to quantify the ratio of labeled protein to total protein. This ratio provides information about the rate of synthesis of the protein of interest. This method will be applied to specimens from patients with hepatitis C virus (HCV) infection who are about to begin HCV treatment. Treatment is known to reduce liver inflammation and collagen content.
This study will investigate the effects of chronic HCV infection and corresponding innate immune activation on the immune response to HBV vaccination. We will recruit chronic HCV patients and healthy control patients for HBV vaccination. We will use RNA Sequencing (RNA-Seq), a relatively new technology for simultaneously measuring the expression of all genes, to determine patients' innate immune status, and learn how this innate immune signature is related to HBV vaccine response. We will then explore the mechanisms by which chronic HCV infection affects different immune cells and functions that are known to be important for an effective HBV vaccine response. These studies will enhance our understanding of the immune effects of chronic viral infection, establish factors that determine effective vaccine responses, and help guide vaccination strategies for HCV patients and other individuals with chronic inflammatory disease.
Metformin treatment during 36 months could be associated with decreased risk of HCC occurrence and liver related death in patients with compensated HCV cirrhosis and insulinoresistance. This study is an ancillary of the observational study from the CIRVIR cohort in which more than 1200 patients with compensated HCV cirrhosis are currently included. participating centers : 26
This is a long-term safety follow-up protocol for subjects who received TT-034 under the B2801001 protocol and consists of monitoring for at least 4.5 years.
Dendritic cells (DC) play a central role in the activation of T-cell responses and have shown to be very immunogenic in preclinical in vivo and in vitro assays. The aims of this study is to assess the efficacy of therapeutic vaccination pilot clinical trial in Genotype 1 HCV patients using autologous DC transduced with a recombinant adenovirus encoding NS3
The primary objective of this study is to assess changes in alanine aminotransferase (ALT) in hepatitis C virus (HCV)-infected subjects given daily doses of JKB-122 for 3 months who have been nonresponsive to, intolerable to, or relapsed from prior interferon-based therapies (pegylated or standard) either alone or in combination with ribavirin or other anti-HCV therapies including direct-acting anti-viral agents.
The primary objective of this registry study is to assess the durability of sustained virologic response (SVR) and clinical progression or regression of liver disease including the incidence of hepatocellular carcinoma following SVR in participants with cirrhosis after treatment with a sofosbuvir-based regimen for HCV infection.
Primary Objectives: To demonstrate the safety of the Aethlon Hemopurifier® when used in extracorporeal blood purification. Secondary Objectives: To quantify the number of viral copies captured by the Aethlon Hemopurifier® during the first and last Hemopurifier treatments using elution methods developed by Aethlon Medical Inc. To measure changes in viral load in patients before and after treatment with the Aethlon Hemopurifier®.
