Active clinical trials for "Hepatitis A"

The purpose of this study is to determine the optimal treatment duration of antiviral therapy for chronic hepatitis B.

The primary purpose of this study is to determine if peginterferon alpha-2a maintenance therapy (90 mcg/week) will lower portal pressure in patients with hepatitis C virus infections and advanced fibrosis or cirrhosis.

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.

This study is designed to compare the efficacy and safety of adefovir dipivoxil 10 mg with lamivudine 100 mg in Japanese patients with compensated chronic hepatitis B over 52-week periods.

Phase I/II trial of KRN7000 in patients with chronic hepatitis C. Study objectives: To evaluate and compare the safety and tolerability of 3 ascending doses of a-GalCer. The primary efficacy parameter: HCV-RNA response at the end of treatment. Secondary efficacy parameter: Serum ALT response. Further objectives of the study are to evaluate the effect of a-GalCer on serum cytokines IFNg and TNFa and on iNKT cells. Number of dose levels: 3 Investigational product: KRN7000 Route of administration: intravenous Dosages and frequency: 0.1, 1, 10 mcg/kg, monthly injection, 3 times (day 0, day 28 and day 56)

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.

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.

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
