Active clinical trials for "Hepatitis C"

Filibuvir, a CYP3A4 inhibitor is being developed for the treatment of chronic Hepatitis C infection. Given the likelihood of co administration of filibuvir and methadone, this study will evaluate the effect of filibuvir on the pharmacokinetics of R/S Methadone.

The purpose of this study is to determine whether BMS-790052 added to Peginterferon Alfa-2a and ribavirin can result in higher cure rates in patients who previously failed therapy and may have limited response to retreatment with Peginterferon Alfa-2a and ribavirin alone.

The purpose of this study is to evaluate the effectiveness of telaprevir administered twice daily versus every 8 hours in combination with Peg-IFN-alfa-2a and ribavirin in treatment-naïve participants with chronic HCV genotype 1 infection.

HIV infection exerts a negative impact on the course of HCV infection. Co-infected individuals progress more rapidly to liver fibrosis, cirrhosis and ESLD compared to those infected with HCV alone. Some of the this accelerated fibrosis may be related to longterm chronic toxicity from protease inhibitor based ART. Hypothesis: Switching from ritonavir boosted-PI based ART regimen to a Raltegravir-based regimen will reduce the rate of hepatic fibrosis progression in HIV-HCV co-infected patients as measured by transient elastography (Fibroscan®) and the AST-to-platelet ratio index (APRI).

This is a single-dose, randomized, cross-sectional comparison study examining the relative safety and resulting blood level profiles after administration of a new boceprevir tablet formulation versus its current capsule formulation for treatment of chronic hepatitis C. In Part 1 of the study participants will receive boceprevir tablets and capsules under fed conditions. In Part 2 of the study a new group of participants will receive boceprevir tablets and capsules under fasted conditions.

This randomized, parallel arm study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) in combination with 2 different doses of ribavirin in patients with chronic hepatitis C, genotype 2 or 3. Patients will be randomized to 4 treatment groups receiving Pegasys (180 mcg subcutaneously weekly) for either 16 or 24 weeks with one of two doses of ribavirin (400 mg or 800 mg orally daily). The anticipated time on study treatment is 16 or 24 weeks with a 24-week follow-up.

This study will evaluate the efficacy and safety of MP-424 with Peginterferon Alfa-2b and Ribavirin (RBV) in patients with genotype 2 hepatitis C, who relapsed after previous treatment.

The purpose of this study is to investigate the efficacy and safety of TMC435 plus PSI-7977 (GS7977) with or without ribavirin in patients who are chronically infected with genotype 1 hepatitis C virus (HCV) and who did not respond to prior peginterferon/ribavirin therapy or are HCV treatment-naive (patients who never received treatment for HCV infection).

The study is a series of 3 linked randomized clinical trials of 6 month duration, with a total of 12 month follow-up, to evaluate the effect of Integrated Stepped Care on drinking outcomes and HIV biologic markers (including VACS index) in HIV-infected patients with unhealthy alcohol use.

This is a Phase 2b, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating Response Guided Therapy using Combinations of Oral Antivirals (GS-5885, tegobuvir, and/or GS-9451) with Peginterferon Alfa 2a and Ribavirin in Treatment Experienced Subjects with Chronic Genotype 1 Hepatitis C Virus (HCV) Infection.
