Active clinical trials for "Hepatitis"

The purpose of this study is to investigate the safety, tolerability, and antiviral activity of ANA598 in patients with genotype-1 chronic hepatitis C infection.

The purpose of the study is to evaluate if continuous subcutaneous delivery of interferon alfa-2b using an external drug pump in combination with the use of oral ribavirin provides a safe and effective treatment for patients with chronic hepatitis C infection as compared to patients who receive standard treatment.

Interferon-based monotherapy has been considered effective to treat acute hepatitis C in ordinary patients. However, the efficacy of this treatment has not been evaluated in prospective interventional studies for dialysis patients. The aim of the study is the evaluate the efficacy of peginterferon alfa-2a monotherapy for 24 weeks in this special clinical setting, and concomitantly evaluate retrospectively the dialysis patients with acute hepatitis C who did not receive intervention as the reference.

The purpose of this study is to determine if administering Mogroside Sweetener "PureLo" (the study substance) for 14 days will lower the hepatitis C viral load and liver function alanine aminotransferase (ALT) levels.

The aim of the study will be to determine if an insulin sensitizing thiazolidinedione plus a lipid lowering agent (statin) improves sustained virologic response rates in patients who have previously not responded or relapsed on standard pegylated interferon and ribavirin therapy.

The purpose of this study is to compare the effectiveness of entecavir plus tenofovir combination therapy with that of entecavir monotherapy. Safety will also be studied.

This study will evaluate the safety and immunogenicity of a novel mixed plasmid DNA (HB-110) combined with an antiviral agent (Adefovir) for the patients with chronic Hepatitis B infection.

The main objective of the study was to evaluate the antiviral activity of tenofovir disoproxil fumarate (tenofovir DF) monotherapy versus emtricitabine (FTC) plus tenofovir DF combination therapy for the treatment of chronic hepatitis B (HBV) in participants in the immune tolerant phase of HBV infection. The efficacy of tenofovir DF monotherapy versus FTC plus tenofovir DF combination therapy was evaluated for suppression of the virus (decrease in HBV DNA), serological response (generation of antibodies to the virus), biochemical response (changes in liver enzymes), and the development of drug-resistant mutations. The safety and tolerability of both tenofovir DF monotherapy and FTC plus tenofovir DF were evaluated by routine monitoring for adverse events and changes in laboratory parameters. Participants were randomized in a 1:1 ratio to receive tenofovir DF monotherapy or FTC plus tenofovir DF. All subjects were to continue on blinded study medication until the last subject reached Week 192. Participants who permanently discontinued study drug (on or before Week 192) were followed for a 24-week treatment-free follow-up period, or until initiation of alternative HBV therapy, whichever occurred first. Subjects who discontinued study drug on or after Week 48 because of hepatitis B surface antigen (HBsAg) loss or seroconversion to antibody to hepatitis B surface antigen (anti-HBs), however, were to have returned for their regularly scheduled through Week 192 and every 16 weeks thereafter until the last subject reached Week 192.

This 48-week open-label study of local manufactured adefovir dipivoxil Tablet evaluates the efficacy and safety of adefovir 10mg once daily in Chinese subjects with compensated CHB. Primary endpoint is proportion of subjects achieving HBV DNA undetectable (<=1000 copies/mL by by Roche COBAS AMPLICOR HBV MONITOR Test) at week 48. Approximately 1250 patients will be recruited in 30 study centers in China. The subjects are offered 48 weeks of open label adefovir dipivoxil treatment, with assessments every three months, after with is a 12-week post study treatment follow-up prior to study completion.

This 2 arm study will evaluate the efficacy and safety of intermittent treatment with PEGASYS in HBeAg negative patients with chronic hepatitis B who have demonstrated virological and biochemical response after treatment with interferon alfa. After 48 weeks therapy with interferon alfa, and 24 weeks treatment-free follow-up, eligible patients will be randomized into the PEGASYS or the observational group. Those in the PEGASYS group will receive 4 therapeutic cycles of long term intermittent treatment with PEGASYS (135 micrograms sc weekly for 12 weeks, followed by a treatment-free period of 12 weeks) and those in the observational arm will receive no specific antiviral treatment. The anticipated time on study treatment is 1-2 years, and the target sample size is 100 individuals.
