Active clinical trials for "Hepatitis, Chronic"

The purpose of this study is to determine if the safety, metabolism, and antioxidant activity of silymarin and green tea extract are changed when they are given in combination to patients with chronic hepatitis C infection.

The purpose of the study was to determine safety and efficacy of 48 weeks treatment with Thymosin alpha 1 (Talpha1) in combination with pegylated interferon (PEGIFN) alpha2a and ribavirin (RBV) in adult patients with chronic hepatitis C (CHC) already treated with, and not responding to previous courses of PEGIFN alpha plus RBV combination therapy, in comparison with a concurrent group treated with PEG IFN alpha2a in combination with RBV and placebo.

This study is to assess the safety and tolerability of sofosbuvir (SOF) 400 mg with and without ribavirin (RBV) and/or with and without pegylated interferon alfa-2a (PEG) in subjects with genotype 1, 2 or 3 hepatitis C (HCV) infection.

GSK2336805 is a hepatitis C virus (HCV) NS5A inhibitor being developed for the treatment of chronic hepatitis C (CHC). This study will assess the safety, antiviral activity, and pharmacokinetics of GSK2336805 alone and in combination with peginterferon alfa 2a and ribavirin in subjects with chronic hepatitis C (CHC).

This study intends to investigate whether addition of PEG-IFN alfa-2a in HBeAg-negative chronic hepatitis B patients who are pretreated with nucleos(t)ide analogues enhances the degree of HBsAg decline.

This study will examine the effectiveness of 15 days of therapy with SCY-635 in reducing hepatitis C virus (HCV) RNA levels.

The purpose of this study is to study the effects of valacyclovir on patients who have hepatitis C and antibodies to herpes simplex type-2. Herpes simplex type 2 is a virus which causes genital herpes. Some persons with genital herpes have sores in their private areas but most persons do not have any symptoms at all. Valacyclovir is a medication which is commonly used to treat or prevent outbreaks of genital herpes. This medication is already approved by the Food and Drug Administration to treat genital herpes. Valacyclovir has not been approved to treat chronic hepatitis C. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and the persons participating will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 3-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center.

This study is a multi-center, randomized, open-label and positive controlled Phase II Clinical trial to assess the efficacy and safety of Ypeginterferon alfa-2b (with Ribavirin), once a week, in 3 dose-groups respectively, for treatment of Chronic Hepatitis C patients, with Pegasys 180mcg/week & Ribavirin as positive control. It is aimed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase III trials, and generate the PK data in hepatitis C patients to satisfy regulatory requirements.

The purpose of this study is to see if treatment of chronic hepatitis C in people who are on opiate replacement therapy such as methadone or buprenorphine (including patient who still inject drugs) is safe and effective.

The general aim of this study is to determine if 3 MIU of IFN-α5 in monotherapy, and 1,5 MIU of IFN-α5 combined with 1,5 MIU of IFN- α2b, are safe dose levels as well as to investigate the antiviral efficacy and pharmacodynamics (PD) of such doses and drugs in treatment-experienced HCV patients with genotype 1 chronic infection, after 29 days of treatment. It is also intended to determine pharmacokinetics (PK) of the safe dose achieved of IFN-α5 in monotherapy.
