Active clinical trials for "Hepatitis A"

The purposes of this study are: To evaluate the efficacy and safety of low-dose versus standard-dose of ribavirin in combination with peginterferon alfa-2a given for 16 weeks in hepatitis C virus (HCV) genotype 2 infected, treatment-naïve chronic hepatitis C patients after achieving a rapid virologic response (RVR,defined as seronegativity of HCV RNA at week 4 of treatment). To evaluate the efficacy and safety of 24-week versus 48-week regimen of peginterferon alfa-2a plus standard-dose of ribavirin in HCV genotype 2 infected, treatment-naïve chronic hepatitis C patients who have no RVR.

The purpose of this study is to measure the effects of anti-HIV drugs on hepatitis C virus (HCV) viral load in people infected with both HCV and HIV.

Interleukin 29 (IL-29) is a substance that is produced in the body to help fight viral infections. The purpose of this study is to test the safety and antiviral effects of PEG-rIL-29 (a man-made form of IL-29) when it is given either by itself at different doses or in combination with the approved dose of ribavirin (an antiviral drug) to subjects with hepatitis C infection who have received no prior treatment for this disease or who have relapsed following previous treatment with PEGylated interferon alpha (PEG-IFN-α), or other form of IFN-α, and ribavirin.

A Phase 3 study to evaluate the efficacy and safety of two dosing regimens of telaprevir in combination with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV).

Combination therapy with pegylated interferon-alpha plus ribavirin has greatly improved the treatment efficacy and is the mainstream of treatment for chronic hepatitis C infection. The efficacy and safety of pegylated interferon-alpha plus ribavirin combination therapy and its impact on the outcome in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma deserve to be elucidated. The purposes of this study are: To evaluate the efficacy and safety of pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma, compare to those without systemic malignancy. To investigate the role of baseline and on-treatment factors on the response to pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma.

The GI-5005 therapeutic vaccine in combination with standard of care or standard of care alone will be injected under the skin of HCV subjects. Patients will be monitored for safety, immune responses and any therapeutic benefits related to the injections including EVR, ETR, and SVR.

This is a randomized, open-labelled, prospective 96-week study comparing the antiviral efficacy and safety of switching to entecavir 0.5mg QD from lamivudine versus maintaining lamivudine 100mg QD treatment in CHB patients currently receiving lamivudine monotherapy.

Researchers want to see whether Sho-saiko-to (SST) can help in patients with chronic hepatitis C. Chronic hepatitis C may cause swelling within the liver and this can lead to scar tissue. In some patients, severe scarring of the liver, liver failure and liver cancer can occur. Standard treatment for chronic hepatitis C is a drug called interferon with or without another drug called ribavirin. There are a number of side effects that some patients are unable to take. Other patients may have an initial response, but then the virus and the inflammation come back. Sho-saiko-to is an herbal medicine that has been used for many years in Asia to treat liver disease. The purpose of the study is to evaluate whether Sho-saiko-to may improve liver swelling and injury caused by chronic hepatitis C.

The purpose of this research study is to test the safety, tolerability, and effectiveness of the drugs Pegasys and Copegus when used for hepatitis C genotypes 6, 7, 8, and 9. Patients are randomly assigned (by chance) to either Treatment Group A (Pegasys and Copegus for 24 weeks) or Treatment Group B (Pegasys and Copegus for 48 weeks).

This study will examine the safety, tolerability and plasma pharmacokinetics of multiple doses of MK-3281 in healthy male participants in Part I, and in Hepatitis C Virus (HCV)-infected male participants in Part II. The clinical efficacy of MK-3281, as measured by viral load reduction, will also be assessed in Part II. The primary hypothesis is that twice daily administration of MK-3281 for 10 days in healthy adult male participants and for 7 days in HCV-infected male participants is sufficiently safe and well tolerated, based on assessment of clinical and laboratory adverse experiences, to permit continued clinical investigation. The results of this study will guide dose selection for future studies in both healthy participants and HCV-infected participants.
