Active clinical trials for "Hepatitis C, Chronic"

Chronic liver disease are characterized by increased levels of plasma IL-6, but the bioactivity of this cytokine in this disease is not well known. IL-6 receptor complex is regulated by multiple receptors subunits: the soluble form of IL-6 Receptor enhance IL-6 signal by a process called trans-signaling on cells expressing few membrane IL-6 receptors. Soluble gp130 is the natural inhibitor of IL-6 trans-signaling. The aim of this study is to characterize circulating and liver levels of theses compounds of IL-6 receptor complex, to unravel the bioactivity of IL-6 in this disease.

The aim of this study is to characterize neutrophil function in patients undergoing chronic hepatitis C triple therapy with protease inhibitors in comparison to dual therapy with peginterferon and ribavirin and with interferon free treatment regimen to thereby elucidate the possible mechanisms of protease-inhibitor associated infections.

This study seeks to provide evidence of the effectiveness and obtain patient reported outcomes (PRO) and work productivity data of the interferon-free regimen of paritaprevir (PTV)/ritonavir (r) + ombitasvir (OBV), +/- dasabuvir (DSV), +/- ribavirin (RBV) in chronic hepatitis C virus infected patients.

The interferon-free combination regimen of ombitasvir/paritaprevir/ritonavir/ with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well-controlled conditions. This observational study was the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Belgium in a clinical practice patient population.

The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions. This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Germany in a clinical practice patient population.

This study will evaluate the safety and efficacy of sofosbuvir (SOF)-based regimens administered as per the approved prescribing information in adults with chronic hepatitis C virus (HCV) infection treated in routine clinical practice in India.

HCV infection is the most frequent cause of liver chronic disease, cirrhosis and hepatocellular carcinoma in western countries. To date, the standard antiviral treatment, including pegylated interferon (PEG-IFN) plus ribavirin (RBV), has relatively low effectiveness in patients infected with genotype 1 and 4, and is associated with important adverse side effects, that lead to treatment interruption in approximately 30% of cases. The recent association of first generation HCV- specific direct-acting antiviral agents (DAAs) (telaprevir and boceprevir) to standard treatment has resulted in higher SVR rates, also in patients infected with genotype-1 HCV and in non responders to PEG-IFN plus RBV. While several new DAAs are in development, the ultimate goal is represented by IFN-free regimens, that will provide a great advantage in terms of patients adherence to therapy and quality of life. In this context, prospective observational studies are needed to evaluate the real and long-term impact of the new DAAs in the clinical practice, in terms of efficacy, safety, costs and impact on patients quality of life. Italy is the European country with the greatest number of HCV infected people (average, 3% of population), with higher prevalence in the center and in the south of the country, especially in older individuals, and the highest mortality caused by hepatocellular carcinoma. Genotype 1 is the most frequent one (in more than 50% of infected people). DAAs were approved at the end of 2012. For these reasons, Italy represents an interesting context for collecting data on long-term efficacy, safety and tolerability of new anti-HCV treatments. The PITER cohort study, developed in the frame of Italian Platform for the study of the therapy of viral hepatitis a prospective observational study, is based on a large cohort of HCV infected patients from more than 100 clinical centers distributed on the whole national area. The main aims of the PITER longitudinal cohort study are: 1) to produce of an ongoing and continuously updated picture of the changing epidemiology of HCV infection in the country; 2) to evaluate in a real-life setting the expected impact of DAAs on the natural course of infection and on long-term morbidity and mortality.

Objectives: 1) To evaluate la proportion of hepatitic C virus (HCV)-monoinfected patients who show sustained virologic response (SVR) to treatment including direct-acting antivirals (DAAs) in the clinical practice in clinical units that treat infectious diseases and 2) to determine the frequency of adverse events, including those that are severe and/or cause treatment interruption, in DAA-based therapy in this setting. Design: Multicentric, prospective post-authorised cohort study. Setting: Hospitals of the Hepatitis Study Group (GEHEP) of the Spanish Society of Infectious Diseases and Microbiology (SEIMC). Study population: HCV-monoinfected patients that initiate DAA-based treatment outside clinical trials. Variables: The primary efficacy outcome variable is the proportion of patients who reach undetectable HCV-RNA 12 weeks after the scheduled end of therapy (SVR12). The primary safety outcome variable is the percentage of subjects who discontinue therapy due to adverse events. Statistical analysis: A descriptive study will be performed, as well as a double sensibility analysis of the frequency of SVR12 using both an intention-to-treat and an on-treatment approach. Those variables that are associated with SVR12 with a p-value <0.2 will be included in a logistic regression analysis in which SVR12 will be the dependent variable.

This study will collect and evaluate information on the safety and efficacy of Sovaldi-based regimens in routine clinical practice in Mexico. The primary objective of this study is to assess the rates of serious adverse events/reactions (SAEs/SADRs) and adverse events/reactions (AEs/ADRs) in adult participants with chronic hepatitis C virus (HCV) infection treated with Sovaldi in routine clinical practice.

Hepatitis C virus (HCV) chronic infection affects 200 million people worldwide. HCV antiviral treatment has evolved rapidly since 2011. The use of pegylated interferon (PEG-INF) with ribavirin (RBV) has supposed high serious adverse events (SAEs) and low efficacy, especially in patients with cirrhosis. The introduction of 1st generation protease inhibitors (PIs) in genotype-1 (GT1) HCV, such as boceprevir (BOC) and telaprevir (TVR), improved the efficacy but increased the SAEs. Currently, interferon-free direct-acting antivirals (IF-DAAs) achieve great effectiveness with minimum SAEs. However, studies evaluating efficacy and safety of DAAs in cirrhotic patients are limited in real clinical practice. The aim of our study is to evaluate in HCV-cirrhotic patients the efficacy and safety of 3 treatment strategies (PEG-IFN/RBV, PEG-IFN/RBV/PIs, and IF-DAAs) in routine practice according to European guidelines from 2010 to 2015. The secondary aim is to evaluate the impact of sustained virological response on gastroesophageal varices (GOV).
