Active clinical trials for "Hepatitis C, Chronic"

Patients with chronic hepatitis C who did not respond to previous antiviral treatment develop liver fibrosis leading to cirrhosis. Maintenance low dose pegylated interferon therapy of fibrosis is currently under investigation in large multicenter trials. The aim of our study is to assess if peginterferon alpha2b plus ribavirin is more efficient than peginterferon alpha2b alone. 454 patients will be randomized between the 2 arms and the efficacy will be assessed, after 3 years of treatment, on Metavir liver fibrosis score improvement.

The purpose of this 12-week study was to assess in subjects with chronic hepatitis C (treatment-naïve, genotype 1) receiving weight-based doses of ribavirin the early virologic response to the 480 ug dose level of Locteron™, dosed every 2 weeks, in comparison with 1.5 ug/kg PEG-Intron™ dosed weekly.

The primary objective is to assess the safety, efficacy and tolerability of the combination of PEG-Intron plus REBETOL in pediatric subjects with chronic hepatitis C. The secondary objective is to measure the multiple-dose pharmacokinetics of PEG-Intron and REBETOL in pediatric subjects with chronic hepatitis C.

The effects of treatment with different doses of PEGASYS in combination with different doses of ribavirin will be evaluated in patients with CHC genotype 1 who have a high viral titer, body weight greater than 85kg (187lbs) and no prior treatment with interferon. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.

This single arm study will evaluate the efficacy and safety of PEGASYS (180 micrograms sc weekly) plus ribavirin (1000-1200mg po daily) in treatment-naive Latino patients versus non-Latino Caucasian patients with chronic hepatitis C- genotype 1. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ patients.

The purpose of this study is to examine the safety and effectiveness of GI262570 compared to placebo (a pill that looks exactly like GI262570 but contains no active medicine) in improving specific tests that indicate the degree of liver fibrosis (scarring). Subjects who are enrolled in the study must have had prior treatment with interferon (either pegylated or standard interferon) plus ribavirin for at least 12 weeks to treat their hepatitis C, but either failed to clear the virus or didn't tolerate the treatment.

The presence of insulin resistance (IR) appears to be a key factor in the development of steatosis and disease progression in patience with Hepatitis C virus (HCV) genotype-1 infections similar to levels in Non-alcoholic fatty liver disease (NAFLD). The objective of this study is to determine whether Pioglatizone, when given along with Interferon and Ribavirin, reduces insulin resistance and lowers HCV viral levels and improved response in patients who have HCV genotype-1 infection when compared to a placebo.

In order to prevent organ rejection, patients receiving liver transplants currently require life-long treatment with immune system-suppressing medications to prevent the rejection of the transplanted liver. However, these medications can cause long-term side effects, such as infection, kidney problems, diabetes, and cancer. In patients infected with hepatitis C virus (HCV), these medications may increase the risk of HCV infection in the transplanted liver. The purpose of this study is to determine whether a slow withdrawal of immune system-suppressing medications is safe in two groups of subjects: those who receive a liver transplant due to HCV, and those who receive a liver transplant due to non-immune, non-viral causes of liver failure. The study will also look at whether slow withdrawal will help reduce the long-term side effects of immune system-suppressing medications and decrease the chance for HCV infection of the new liver in transplant patients with HCV.

This study evaluated the efficacy and safety of the combination of peginterferon alfa-2a plus ribavirin in treatment-naïve patients with HCV genotype 1b infection, compared with peginterferon alfa-2a monotherapy. Additionally, the study evaluated the efficacy and safety of the combination of peginterferon alfa-2a plus ribavirin in patients with CHC who had failed to respond to previous conventional-interferon based therapy.
