Active clinical trials for "Hepatitis C"

This Registry is designed to obtain long term data on participants who have failed to achieve sustained virologic response (SVR) while receiving at least one Gilead oral antiviral agent (OAV) in a previous Gilead-sponsored hepatitis C virus (HCV) study.

To study retreatment in patients who failed prior treatment with interferon alpha (pegylated or non-pegylated) with or without ribavirin in a real-life setting in an observational/noninterventional study.

The objective of the study is to evaluate the safety and efficacy of PegIntron plus Rebetol combination therapy administered to patients with chronic hepatitis C. The study will exclude (1) subjects with HCV genotype 1 and high viral load, and (2) interferon-naïve subjects with low viral load. It is being conducted as a post-approval commitment, in accordance with the Ministry of Health, Labour and Welfare's guideline on Good Post-marketing Study Practice. Post-marketing surveys are not considered applicable clinical trials and thus the results of this survey will not be posted at its conclusion. The results will be submitted to public health officials as required by applicable national and international laws.

Alcoholic liver disease is characterized by circulating T cell activation and liver T cell infiltration but their phenotype is poorly studied. The aim of the study is to test the hypothesis that the (CD4+ T cell secreting Interleukin-17) Th17 pathway is involved in alcoholic liver disease.

Hepatitis C Virus is constantly evolving genetically, particularly in response to the immune system. This is an observational study to examine if immunosuppressants particularly calcineurin inhibitors taken by transplant patients in order to avoid organ rejection causes predictable changes in the genetics of this virus that might be important in order to treat it effectively.

The objective of this study is to evaluate patient satisfaction in hepatitis C patients receiving PegIntron pen plus Rebetol. The rationale is that the effectiveness of treatment is correlated with adherence to the prescribed regimen which, in turn, is affected by the ease of use and accuracy of treatment administration. Since the PegIntron pen is a novel device, the results of this study will be used to improve the training of patients and healthcare providers in PegIntron pen use.

This single arm study will investigate the predictive value of a week 4 virological response on sustained virological response in patients with chronic hepatitis C, genotype 2 or 3, treated with PEGASYS + Copegus. Eligible patients will be treated with PEGASYS 180 micrograms/week sc + Copegus 800mg/day po; those who have a virological response at week 4 will continue to be treated for 24 weeks, followed by a 24 week treatment-free follow-up. Non-responders at week 4 will be entered into a separate protocol (MV21371) to receive PEGASYS + Copegus for 24 or 48 weeks. The anticipated time on study treatment is 3-12 months, and the target sample size is 100 individuals.

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 Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) trial is a multicenter clinical trial conducted to assess the effects of long-term antiviral drug therapy on the progression of liver disease in patients who have advanced chronic hepatitis C and have not responded to prior therapies. Chronic hepatitis C is a long-lasting viral infection affecting the liver that may lead to permanent liver damage and cirrhosis (replacement of healthy liver cells by scar tissue). If left untreated, a proportion of patients with chronic hepatitis C will be at risk for complications of liver disease. The drug therapy in the HALT-C trial was designed to clear the hepatitis C virus from the patient s system in order to prevent or mitigate these potential complications. The purpose of this research is to determine if patients with chronic hepatitis C who experienced clearance of hepatitis C virus (known as a sustained virologic response, or SVR) during the HALT-C trial have developed any complications of their liver disease. This study will include 180 subjects who participated in the initial phase of the HALT-C trial and experienced an SVR. The participants will visit the National Institutes of Health for an in-person study visit. During the visit, patients will have blood drawn for lab tests to monitor the progress of their liver disease, and may be asked to undergo an ultrasound examination of the liver to detect any abnormalities that may be attributed to liver cancer. Patients will also answer questions about their medical history particularly any outcomes or events related to their hepatitis C that have occurred since the HALT-C trial and may be asked to sign a release of information to allow researchers to obtain medical records from other clinics or physicians where they have received treatment. ...

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.
