Active clinical trials for "Hepatitis C, Chronic"

This study will examine the effectiveness of low-dose peginterferon and ribavirin therapy for certain patients with chronic hepatitis C-a liver disease that, in some patients, can progress to cirrhosis of the liver, liver cancer, and liver failure.

SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 as a treatment for patients with chronic hepatitis C-related thrombocytopenia who are potential candidates for antiviral treatment with pegylated interferon and ribavirin. The study will be conducted in two phases, Parts 1 and 2. In Part 1, study subjects will be randomized to 4 weeks of SB-497115-GR or placebo administered daily without antiviral therapy. Subjects who successfully complete Part 1 (platelet count 70,000/µL for Pegasys and platelet count 100,000/µL for PEG-Intron) will then proceed to Part 2. In Part 2, subjects will receive an additional 8 weeks of SB-497115-GR or placebo administered daily with antiviral therapy.

The purpose of this study is to determine the safety and efficacy of peginterferon alfa-2a (PEG-2a) in combination with ribavirin (RV) and PEG-2a alone for the treatment of chronic hepatitis C virus (CHC) infection in children. The purpose of this study is also to determine whether PEG-2a in combination with RV or PEG-2a alone will result in a longer response rate in children with CHC.

To evaluate the safety and tolerability of two different doses of Consensus Interferon-Alpha and Interferon Gamma-1b with or without ribavirin in patients with chronic hepatitis C who are non-responders to PEG-IFN-a 2a or PEG-IFN-a 2b plus ribavirin.

This study is being conducted to compare the safety, effectiveness and tolerance of valopicitabine (NM283) when used alone and when valopicitabine is used together with pegylated interferon in hepatitis C treatment failure patients. These results will be compared against the results of treatment with pegylated interferon plus ribavirin, the current standard therapy for treatment of hepatitis C viral infection.

This is a controlled, randomized, parallel-groups, open-label, multinational study designed to evaluate the efficacy and safety of PEG-Intron® (pegylated interferon alfa-2b) plus Rebetol® (ribavirin) in subjects with chronic hepatitis C. It is designed to evaluate whether 72 weeks of treatment with PEG-Intron plus Rebetol is more effective than 48 weeks of treatment in subjects with Genotype 1 chronic hepatitis C who exhibit a slow response to treatment.

This is an extension study of HCV-05-002. The objective of this study is to evaluate the safety and efficacy of celgosivir plus peginterferon alfa-2b, with or without ribavirin, for an additional 36 weeks in patients with chronic hepatitis C genotype 1 infection.

The purpose of this study is to investigate the efficacy and safety of Pegasys® 180μg for subcutaneous (s.c.) injection in interferon (IFN)-treated or IFN-untreated chronic hepatitis C patients except for those infected with genotype 1b of hepatitis C virus (HCV) and a high viral load (≥ 100 KIU/mL). In addition, this study will explore the efficacy and safety of Pegasys® 180μg for s.c. injection given at 2 different periods between 24 and 48 weeks in IFN-untreated chronic hepatitis C patients.

This is a randomized, open-label, multinational study designed to evaluate the "standard" regimen, PegIntron 1.5 µg/kg subcutaneously once weekly plus ribavirin 800-1200 mg daily [Arm PEG2b 1.5/R (24 weeks)], compared to a lower dose regimen, PegIntron 1.0 µg/kg subcutaneously once weekly plus ribavirin 800-1200 mg daily [Arm PEG2b 1.0/R (24 weeks)], using a 24 week treatment duration for both arms. Additionally, the study examined the efficacy of reduced treatment duration: PegIntron 1.5 µg/kg subcutaneously once weekly plus ribavirin 800-1200 mg for 16 weeks [Arm PEG2b 1.5/R (16 weeks)] .

This was an open-label, randomized safety and efficacy trial in adult, treatment-naïve Chronic Hepatitis C (CHC) participants with genotype 1 infection. The study conducted in 2 parts, compared standard-of-care PegIntron (1.5 μg/kg, once weekly [QW]), plus ribavirin (800 to 1400 mg/day), for 48 weeks to five treatment paradigms containing boceprevir (SCH 503034) 800 mg thrice a day (TID). The five treatments included boceprevir (BOC) plus standard-of-care for 28 or 48 weeks, with and without a 4-week lead-in with PegIntron (PEG) and ribavirin (RBV), and exploration of PegIntron plus low-dose ribavirin (400 to 1000 mg/day) plus boceprevir for 48 weeks.
