Active clinical trials for "Hepatitis C, Chronic"

The primary purpose of this study is to determine whether the hepatitis C virus continues to remain unable to be detected in subjects who were previously treated with Asunaprevir (BMS-650032) and/or Daclatasvir (BMS-790052) and achieved sustained virologic response.

This multicenter, observational study will assess the efficacy and the safety of Pegasys (peginterferon alfa 2a) in dual- or triple therapy in patients with chronic hepatitis C. Patients will receive Pegasys and/or ribavirin and/or a protease inhibitor according to local guidelines. Data will be collected for 96 weeks.

This prospective observational study will assess the insulin resistance and its impact on sustained virological response in patients with hepatitis C treated with Pegasys and Copegus. Data will be collected from each patient during the up to 72 weeks of treatment and for 24 weeks of treatment-free follow-up.

The efficacy of combination antiviral therapy for chronic hepatitis C is influenced by many factors. Important patient-specific factors include, age, gender, race, body weight. Important virus-specific factors include HCV genotype and serum HCV RNA level. Finally, important treatment-related factors include the type of interferon, dose of ribavirin and the duration and adherence to treatment. Despite the importance of patient- and virus-specific factors, the most important indicator of treatment success is a rapid, profound and sustained decrease in serum HCV RNA levels after the start of treatment. The on-treatment virological response can thus be used to predict the probability that a given patient will achieve an SVR if they remain on therapy. It can also be used to individualize the duration of treatment. In this study, treatment for patients with chronic hepatitis C was individualized on the basis of clinical characteristics and the on-treatment virological response. The aim was to investigate the usefulness of undetectable HCV RNA levels at week 4 (RVR) and 12 in tailoring the duration of treatment and predicting SVR in Chinese patients with chronic hepatitis C.

This observational study will evaluate the predictive value of rapid virological response (RVR) and early virological response (EVR) on sustained virological response (SVR) by stage of liver fibrosis in treatment-naïve patients with chronic hepatitis C genotype 1 initiated on treatment with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin). Patients will be followed for 48 weeks of treatment and up to 24 weeks of follow-up.

In this project, the investigators aim to study the role of biliverdin reductase A (BLVRA) in HCV infected patients prior and during/after standard antiviral therapy in association with viral clearance, disease progression and treatment response and in comparison with healthy subjects.

The purpose of this study is to investigate T-cell mediated immune responses to HIV-1 and HCV and determine how these responses are affected by HCV treatment and correlates to response. Furthermore, to study Interferon-inducible protein-10 (IP-10) dynamics during HCV treatment, and correlate this to treatment outcome.

The current gold standard for treatment of chronic hepatitis C (CHC) patients is with pegylated interferon plus ribavirin. Drug administration accuracy and ease of use will definitely determine treatment effectiveness. This is the idea behind the development and usage of the PegPen. The goal of this study is to determine the satisfaction grade with this novel device.

The role of the dendritic cells, the most potent antigen presenting cells, in the establishment of chronic hepatitis C is not established. The study aims to define whether the dendritic cells are affected by the hepatitis C virus and whether that bears an impact on the antiviral immune response they generate. The hypothesis is explored by investigating a group of patients prior to and after the initiation of standard treatment for hepatitis C with pegylated Interferon and Ribavirin.

Naïve patients with chronic hepatitis C (CHC) of any genotype will be treated with a standard treatment regimen (pegylated interferon and ribavirin) according to routine clinical practice in Russia. The objective of this study is to examine the influence of insulin resistance on the safety and efficacy of treatment with pegylated interferon and ribavirin and to determine the prevalence of insulin resistance in different populations of CHC patients.
