To evaluate the effect of treatment of insulin resistance in the response of chronic hepatitis C treatment, mesure as HCV-RNA negative at week 72. 4.3.2 Objetivos secundarios To evaluate the efficacy and safety of treatment with metformine to erradicate the insulin resistance of patients with chornic hepatitis C genotype 1 measure as HOMA-IR < 2.
This 2 arm study will assess the efficacy and safety of PEGASYS plus COPEGUS, with or without concomitant pioglitazone, on hepatitis C virus titers in treatment-naive patients with genotype 1 chronic hepatitis C, and insulin resistance. Patients will be randomized to receive either a)PEGASYS 180 micrograms/week + Copegus 1000-1600 mg/day (according to body weight) for 48 weeks or b)16 weeks of pioglitazone (30 mg daily for 8 weeks, then 45 mg daily for 8 weeks), followed by PEGASYS 180 micrograms/week + Copegus 1000-1600 mg/day + pioglitazone 45 mg daily for 48 weeks. The anticipated time on study treatment is 1-2 years, and the target sample size is 100-500 individuals.
The purposes of this study are: 1. To evaluate the efficacy and safety of low-dose versus standard-dose of ribavirin in combination with peginterferon alfa-2a given for 16 weeks in hepatitis C virus (HCV) genotype 2 infected, treatment-naïve chronic hepatitis C patients after achieving a rapid virologic response (RVR,defined as seronegativity of HCV RNA at week 4 of treatment). 2. To evaluate the efficacy and safety of 24-week versus 48-week regimen of peginterferon alfa-2a plus standard-dose of ribavirin in HCV genotype 2 infected, treatment-naïve chronic hepatitis C patients who have no RVR.
Debio 025 (alisporivir) is an oral cyclophilin inhibitor with a new mechanism of action demonstrating potent anti-hepatitis C virus (HCV) activity in pre-clinical models and patients. The current standard of care (SOC) in HCV patients consists of a combination of peg-IFN alpha and ribavirin. Treatment duration and ribavirin dose depend on the genotype treated. Only 40-50% of patients with genotype 1 achieve a sustained viral response (SVR). This study assesses whether Debio 025 administered in combination with peg-IFN alpha 2a and ribavirin can improve the outcome of treatment in this group of patients.
Treatment with peginterferon plus daily low dose (800 mg) or weight-based ribavirin (800-1400 mg) for 24 to 48 weeks has achieved 70-93% sustained virologic response (SVR) rates in patients with genotype 2 or 3 chronic hepatitis C (CHC). Recently, a large randomized study has shown that patients with genotype 2 or 3 CHC have comparable SVR rates for those who received peginterferon for 24 or 48 weeks, and who received daily low dose (800 mg) or standard dose (1000-1200 mg) ribavirin. Therefore, the currently recommended treatment for these patients is 24 weeks of peginterferon plus low dose ribavirin. Because of the high response rates, several studies have shown that when these patients had rapid virologic response (RVR), defined as undetectable hepatitis C virus (HCV) ribonucleic acid (RNA) levels, at week 4 of peginterferon plus weight-based ribavirin, 12-16 weeks of treatment could have 82-94% SVR rates. However, treatment with peginterferon plus low dose ribavirin for 24 weeks showed significantly higher SVR rates than that for 16 weeks (85% versus 79%) in these patients who achieved RVR. While studies showed concordant results in SVR rates for patients with genotype 3 CHC who received peginterferon plus low dose or weight-based ribavirin for 16 or 24 weeks, the SVR rates stratified by RVR showed great differences in patients with genotype 2 CHC who received such treatment. Currently, there are no studies on the direct comparison of low dose versus weight-based ribavirin, and of 16 to 24 weeks of treatment stratified by RVR for patients with genotype 2 CHC. The investigators aimed to conduct a randomized trial to determine the optimal ribavirin dose and treatment duration of peginterferon plus ribavirin for patients with genotype 2 CHC based on RVR studies.
To determine the efficacy and safety of Peginterferón alfa-2a (40 KD) plus Ribavirin in patients who have relapsed or not responded to a previous suboptimal therapy based in Interferon.
The purpose of this study is to assess the ability of eltrombopag to maintain a platelet count sufficient to facilitate initiation of antiviral therapy, to minimise antiviral therapy dose reductions and to avoid permanent discontinuation of antiviral therapy. The clinical benefit of eltrombopag will be measured by the proportion of subjects who are able to achieve a Sustained Virological Response (SVR).
The primary objective is to determine the safety of sub-cutaneous (SC) injections of TG4040 in non-cirrhotic, treatment-naïve patients chronically infected with HCV (genotype 1). Patients will be sequentially treated at an escalting dose of TG4040. All patients will be followed up to at least 6 months after his/her first injection. In addition, all patients treated at the highest dose will receive a TG4040 boost injection 6 months after the first injection, and will be followed up during an additional 6-month period.
The purpose of this study is to explore the efficacy, safety, tolerability, pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time), and pharmacokinetic-pharmacodynamic relationships of telaprevir administered in two different doses in combination with two standard therapies commercially available for chronic (lasting a long time) genotype 1 Hepatitis (inflammation of the liver) C virus (HCV) infection.
