Active clinical trials for "Hepatitis C, Chronic"

This multicenter study was to evaluate subjects with chronic genotype 2 or 3 HCV infection who were interferon (IFN) ineligible, IFN intolerant or unwilling to take IFN. Participants were randomized in a 3:1 ratio to receive sofosbuvir (SOF)+ribavirin (RBV), or placebo to match SOF+placebo to match RBV. Randomization was stratified by presence/absence of cirrhosis. Approximately 20% of participants may have had evidence of cirrhosis at screening.

In the current practice patients with normal levels of ALT were not treated. However, a percentage of patients will present an advanced grade of fibrosis and cirrhosis. Another reason to treat is the similar response to the treatment than elevated ALT patients published recently in mono-infected patients. The investigators have not data concerning the evolution and response to the treatment in co-infected patients with normal ALT. In the story of treatment chronic hepatitis C of co-infected patients HCV/HIV, sometimes, it assumes a behavior similar between mono and co-infected patients and the results are different. In the case of normal ALT the investigators do not know if the natural history in co-infected patients is similar than the mono-infected patients, and also the response of the treatment. This study prospective and controls is the answer of this question. The main hypothesis is if the response of treatment in co-infected patients is not inferior than mono-infected patients. The objective is to evaluate the efficacy and safety of peginterferon alfa-2a and ribavirin in HIV positive patients with chronic hepatitis and persistently normal ALT. Every CASE (patient with normal ALT) will have a CONTROL (patient with elevated ALT), concerning genotype, gender and hospital.

The study aims to study the outcome of pharmacokinetics-adjusted dose ribavirin (plus pegIFN) on the SVR in chronic HCV patients.

The purpose of this study was to evaluate the safety, tolerability, and efficacy of 12 weeks of treatment with ACH-0143102 and ribavirin in genotype 1b (GT1b), treatment-naive, hepatitis C virus (HCV) participants.

Dose cohorts may be dosed with one of up to 4 possible total weekly doses (0.3 mg, 1 mg, 2 mg, 4 mg). Dose escalation or repetition will be governed by pre-specified safety and activity rules. Subjects will be confined on either days 1-3 and/or days 8-10. Follow-up visits are also required periodically through day 43. Study procedures involve taking blood samples for pharmacokinetic, pharmacodynamic, virologic, and safety assessments.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-072 and ribavirin (RBV) in treatment-naïve participants with genotype 1 chronic hepatitis C virus (HCV) infection.

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 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.

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.
