Active clinical trials for "Hepatitis C, Chronic"

The purpose of this study is to evaluate the safety, tolerability, and efficacy of vaniprevir given in combination with pegylated interferon alfa-2b (peg-IFN) and ribavirin (RBV) versus treatment with peg-IFN and RBV alone in Japanese treatment-naïve participants with chronic hepatitis C (CHC) genotype (GT)1. The primary efficacy hypothesis is that the percentage of participants achieving sustained virologic response 24 weeks after completion of all study therapy (SVR24) in at least one of the vaniprevir arms is superior to the percentage of participants achieving SVR24 in the control arm.

The main purpose of this study is to determine the safety and tolerability of multiple dosing of miravirsen in subjects infected with chronic hepatitis C. Secondary purpose includes assessment of pharmacokinetics of miravirsen and assessment of miravirsen's effect on HCV viral titer.

The purpose of this study is to evaluate the efficacy and safety of TMC435 in combination with peginterferon alfa-2b and ribavirin in chronic genotype 1 hepatitis C virus (HCV)-infected participants who are treatment-naive or treatment-experienced (prior relapser or non-responder to Interferon-based therapy) in Japan.

The purpose of this study is to compare PEG-interferon alfa-2b and two different doses of rivavirin for the treatment of chronic hepatitis C in previously untreated adult subjects

This study evaluated the clinical response of the efficacy and safety of the combination therapy of peginterferon alfa-2a and ribavirin, compared with an antiviral treatment-free group in CHC patients with compensated LC. Additionally, this study evaluated the dosage reactivity and the pharmacokinetic characteristics of the combination therapy of peginterferon alfa-2a and ribavirin in CHC patients with compensated LC.

This 2-arm study will compare the efficacy and safety of treatment with Pegasys (180 µg weekly) plus Copegus (800 mg daily) and Pegasys (180 µg weekly) plus Copegus (1000-1200 mg daily) in interferon-naive patients with CHC genotype 1 co-infected with HIV-1. Treatment will be administered for 48 weeks, and this will be followed by 24 treatment-free weeks. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Liver transplant subjects will be given Mycophenolate (MMF) and Tacrolimus in order to help prevent post-transplant rejection.

Assessment of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of SCH 900518 in Naive or Treatment-Experienced Subjects Infected With Hepatitis C Virus Genotype 1 (Protocol No. P04695)

This study assessed the safety, tolerability, pharmacokinetics, and antiviral activity of multiple oral doses of ABT-450/ritonavir (r), ABT-333 (also known as dasabuvir), or ABT-072 in hepatitis C virus (HCV), genotype 1-infected, treatment-naïve adults.

This randomized, cross-over, open label study will compare the tolerability and handling of application of peginterferon alfa-2a [Pegasys] by autoinjector versus pre-filled syringe in patients with chronic hepatitis C, either on treatment with peginterferon alfa-2a for at least 12 weeks or treatment-naïve for peginterferon alfa-2a. Patients will be randomized to self-injection of 180mcg peginterferon alfa-2a once a week using either an autoinjector or a prefilled syringe for 3 weeks, then switch to use the other method of injection for another 3 weeks. Anticipated time on study treatment is 6 weeks. Target sample size is <100 patients.
