Filter by:This study is being conducted to see if the investigational medication, valopicitabine, is safe to use in combination with ribavirin, a drug approved by the FDA for treating hepatitis C infection.
This 4-arm study will compare the efficacy and safety of PEGASYS induction and maintenance dosing, versus standard fixed dosing in combination with Copegus, and the efficacy and safety of higher dose versus standard dose Copegus in combination with PEGASYS. Patients with chronic hepatitis C (CHC) genotype 1 infection of high viral titer, and baseline body weight ≥85 kg, will be randomized to one of 4 groups, to receive one of the following: a) PEGASYS 180 µg subcutaneously (sc) weekly plus Copegus 1200 mg orally (po) daily; b) PEGASYS 180 µg sc weekly plus Copegus 1400-1600 mg po daily; c)PEGASYS 360 µg sc weekly (induction) followed by 180 µg sc weekly (maintenance) plus Copegus 1200 mg po daily; or d) PEGASYS 360 µg sc weekly (induction) followed by 180 µg sc weekly (maintenance) plus Copegus 1400-1600 mg po daily. Following 48 weeks treatment, there will be a 24-week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
The purpose of this study is to determine whether a 10-day course of therapy with orally administered VCH-759 given at 400-mg, 600-mg or 800-mg three times daily can effectively reduce the amount of circulating virus (i.e., viral load) in patients with early-stage chronic hepatitis C-infection. This study will also evaluate the safety and tolerability of treatment with VCH-759. Blood samples will also be taken to measure the levels of VCH-759 present in plasma at various time points during the treatment period.
This is an exploratory study and is a Phase 3, single-arm, multi-center, open-label study of pegylated interferon alfa-2b, PEG-IFN alpha-2b (PEG-Intron) and ribavirin (RBV) to determine the sustained virologic response (SVR) at 24-week follow-up to 48 week in subjects after orthotopic liver transplantation (OLT) with chronic hepatitis C (HCV) recurrence.
This 4 arm study will compare the safety and tolerability of HCV polymerase inhibitor pro-drug in combination with PEGASYS +/- COPEGUS with the standard of care therapy of PEGASYS + COPEGUS, in treatment-naive patients with CHC, genotype 1. Patients will be randomized to receive 1500mg or 3000mg po bid of HCV polymerase inhibitor pro-drug + PEGASYS, 1500mg of HCV polymerase inhibitor pro-drug + PEGASYS + COPEGUS or PEGASYS + COPEGUS for 4 weeks. All patients who receive at least one dose of study medication will receive open label PEGASYS + Copegus for an additional 44 weeks after the 4 week experimental period. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.
In France, 50% of hepatitis C virus carriers develop chronic clinical hepatitis, which may lead to cirrhosis and liver transplantation. Transplant infection by hepatitis C virus is constant after transplantation and recurrence causes chronic liver disease in 50 to 80% of cases. The aim of this study is to assess the efficacy of cyclosporin on C virological response. Patients included in the Transpeg 1 study and non-responder or with a recurrent disease will be switched from their tacrolimus therapy to cyclosporin, in association with a 1 year peginterferon alfa-2a / ribavirin bitherapy. Efficacy will be assessed by the percentage of patients with a negative qualitative PCR after 19 months of cyclosporin treatment.
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.
Compare the effectiveness of telaprevir (VX-950) in combination with Pegylated Interferon Alfa 2a (Peg-IFN-alfa-2a) with and without Ribavirin (RBV) in reducing plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels
Chronic hepatitis C virus (HCV) infection is associated with an increased risk for the development of type 2 diabetes and HCV infection itself may promote insulin resistance, irrespective of the severity of liver disease. Insulin resistance seems to be genotype specific and may play a role in fibrogenesis in chronic hepatitis C. In an “in vitro” model, increased levels of insulin may promote increased HCV replication. RATIONALE Decreased insulin resistance and reduced hyperinsulinemia may facilitate the efficacy of anti-viral drugs on HCV replication.
Chronic hepatitis C may relapse in simple chronic hepatitis C patients who initially obtained sustained virologic responses. Although the HCV SVR could be maintained in around 90%, the remaining 10% of these patients may develop hepatitis C relapse during follow-up. Therefore, it is important to follow up the long-term of these patients with dual chronic hepatitis B and C. From another aspect, for the treatment of chronic hepatitis B, the virologic and serologic responses may also not be durable. Alternatively, previous studies suggested that the therapeutic efficacy might not be seen in the study period, and incremental response might occur during long-term follow-up. Therefore it is also important to clarify the long-term outcome of treatment in this dually infected population. Evaluation of the long term effects of treatment with peginterferon alfa-2a plus ribavirin for patients with chronic hepatitis C/ hepatitis B co-Infection and chronic hepatitis C in the original study ML17862 is important. This present protocol is thus to assess whether the HCV SVR is sustained and to assess the durability of the HBV virologic and serologic responses or any incremental response during a 5-year follow-up period, including six months after end of the therapy in the original study and an additional 4 and half years in this project (5 years overall follow-up after the end of treatment). Specifically, we wish to assess the (1) sustained virologic response (SVR) of HCV in both populations, (2) incidence of HBsAg loss and HBsAg seroconversion (HBsAg loss and appearance of anti-HBs) in dually infected population, (3) ALT normalization or flare off-treatment during both populations, (4) reductions of HCV RNA from the original baseline levels in the two patient populations, and (5) reduction of serum HBV DNA off-treatment in the dually infected population.
