Active clinical trials for "Hepatitis C"

The purpose of the study are the following: 1) Pilot test and conduct baseline and 3 month follow up assessments to evaluate the preliminary efficacy of the DVD-based HIV/HCV intervention by randomly assigning 210 Latino corrections-involved, outpatient abuse treatment clients to either the experimental intervention or to a wait list control group; and 2) to evaluate both participant and interventionist acceptability of this novel DVD-based intervention. They study hypothesis are the following: participants in the intervention condition will report greater reductions in sexual risk behaviors (e.g., unprotected sexual contact) from baseline to 3 month follow-up compared to the control group; participants will report greater reductions in drug risk behaviors (e.g., sharing injection equipment, drug use during sex) from baseline to 3 month follow-up compared to the control group; participants who report more HIV prevention information, motivation, and behavioral skills will report fewer sexual risk behaviors.

The purpose of this study is to evaluate the pharmacokinetic interactions between the hepatitis C NS3 protease inhibitor boceprevir and the calcium channel blockers amlodipine and diltiazem in healthy volunteers.

The purpose of this study is to determine the change from baseline in HCV Ribonucleic acid (RNA) on Day 4 following three days of dosing with BMS-929075 in chronically genotype subtype 1a and 1b HCV infected subjects

The purpose of this study is to evaluate the effects of a brief motivational intervention in reducing risky injection practices among injecting drug users (IDUs). The investigators hypothesis is that motivational intervention will be more effective than educational intervention in reducing risky injection practices among IDUs.

In this study, researchers from UCLA and Friends Community Center will work together in designing a program to assist young homeless stimulant-using gay and bisexual homeless men to complete the hepatitis vaccine and in reducing drug and sexual activity. Using nurse case management strategies, found successful with homeless adults as well as contingency management strategies, found successful with gay and bisexual homeless adults by the community partners, the investigators will evaluate the effectiveness of a program that combines both strategies. As stimulant use threatens to increase homeless persons' risk of exposure to hepatitis A and B viruses, particularly among young users who may not yet be HBV-infected, this research is targeted to engage this group in treatment, until they are suitably protected from HBV, and hopefully reduce risk for HCV and HIV as well.

This study will evaluate the safety, tolerability, and efficacy of vaniprevir when administered concomitantly with pegylated interferon (peg-IFN) and ribavirin (RBV) to treat treatment-naive genotype 1 hepatitis C virus (HCV)-infected patients.

The purpose of this study is to evaluate the safety and effectiveness of an investigational vaccine (TG4040) to prevent hepatitis C virus (HCV) infection. The primary goal of this study is to determine the safety of increasing doses of TG4040 versus placebo (an inactive substance) in subjects chronically infected with HCV. Approximately 85 patients, ages 18-65 years, with chronic HCV infection will be enrolled in this study at two sites, Saint Louis University and Cincinnati Children's Hospital. Volunteers will receive doses of TG4040 and placebo by injections into the thigh on different days, depending on which study group they belong to. Safety will be checked before doses are increased, and each participant will receive the study vaccine, TG4040, at some point during the study. Each subject will participate in the study for 8 months. This study may help produce a new vaccine that would improve control of HCV.

The purposes of this study are to evaluate the safety, tolerability, and effectiveness of a vaccine (the HCV E1/E2/MF59 vaccine) against hepatitis C (HCV). The vaccine will be given to 60 healthy adult volunteers (aged 18-45 years) and the study will compare the immune system (the body's protective response) response to the HCV E1/E2 vaccine given at different dosage levels: 4 micrograms, 20 micrograms, or 100 micrograms in MF59 adjuvant (substance that can improve vaccine effectiveness). The volunteers will be assigned randomly (by chance) to 1 of 4 different groups. Volunteers in each group will receive a shot of the vaccine or a placebo (shot with no medication). Participants will be involved in study related procedures for up to 71 weeks, which includes blood samples, recording symptoms on a diary card, and 4 vaccine or placebo injections.

The purpose of this study is to determine whether low-dose peg-interferon plus ribavirin therapy is effective in the prevention of hepatocellular carcinoma (HCC) in patients who had the curative resection of primary HCC.

To investigate the effect of silymarin, derived from the milk thistle plant, Silybum marianum, in preventing and reversing the complications of chronic infection with hepatitis C virus and/or clearing hepatitis C infections.
