Active clinical trials for "Hepatitis C"

Australian Trial in Acute Hepatitis C (ATAHC) A prospective non-randomised dual arm longitudinal cohort of newly acquired hepatitis C infection into which participants will be enrolled and then followed at 3 monthly intervals over a 3 year period. All participants will be offered a 24 week course of pegylated interferon alfa 2a which will be commenced within 12 weeks of screening (patients coinfected with HIV will be offered 24 weeks with pegylated interferon alfa 2a plus ribavirin).

The purpose of this pilot study is to evaluate efficacy and safety of addition of IL-2 to pegylated interferon alpha 2a and ribavirin in HIV-HCV coinfected patients non-responders after three months of standard therapy with pegylated interferon alpha 2a and ribavirin. IL-2 may enhance numbers and function of CD4 T lymphocytes and specific anti-HCV immune responses and could participate to the control of HCV replication

The objective of the study is to evaluate the safety and efficacy of celgosivir plus peginterferon alfa-2b, with or without ribavirin, for 12 weeks in patients with chronic hepatitis C genotype 1 infection.

The purpose of this study is to assess the safety and efficacy of repeated intravenous infusions of EMZ702 in combination with pegylated interferon and ribavirin in patients with chronic hepatitis C genotype 1.

This purpose of this study is to determine the safety and effectiveness of viramidine to ribavirin in chronic hepatitis C patients who have never before recieved treatment.

Response to a second-line anti-HCV treatment in non responder patients to a first-line dual therapy remains very poor. Preliminary studies of amantadine suggest that this drug could be potentially effective to treat hepatitis C.

This Phase 3 clinical study is designed to evaluate the safety, tolerability, and efficacy of two dose levels of Infergen (interferon alfacon-1, CIFN) plus Ribavirin administered daily for 48 weeks and no treatment in patients chronically infected with hepatitis C who are nonresponders to previous pegylated interferon alfa plus ribavirin therapy and participated during at least 24 weeks of no treatment in IRHC-001. At the time of randomization into IRHC-001, the no treatment arm patients will be concurrently randomized in a 1:1 ration to receive Interferon Alfacon-1 (9 or 15 µg) + Ribavirin (both administered daily) or no treatment for up to 48 weeks. Patients will not be eligible for consideration to receive treatment in IRHC-002 until they have completed a minimum of 24 weeks of participation in IRHC-001. The protocol and informed consent form that will be used must be approved by the Investigator's Institutional Review Board (IRB)/Independent Ethics Committee (IEC) before the study is initiated.

The objective of the study is to evaluate the safety and efficacy of PEG-Intron versus no treatment for the prevention of fibrosis progression in adult participants with moderate to severe liver fibrosis secondary to chronic hepatitis C, who failed PEG-Intron plus Rebetol treatment in protocol P02370 (NCT00039871).

The purpose of this research study is to test the safety and effectiveness of Interferon gamma-1b (IFN-g 1b) injected subcutaneously (under the skin) for the treatment of advanced liver fibrosis and cirrhosis in patients with chronic hepatitis C infections. IFN-g 1b is not currently approved for the treatment of liver fibrosis.

The objective of the study is to evaluate the safety and efficacy of PEG-Intron vs. no treatment for the prevention of disease progression in adult subjects with compensated cirrhosis secondary to chronic hepatitis C, who failed to respond to therapy with an a interferon plus ribavirin.
