Filter by:This single arm study will provide treatment or re-treatment with PEGASYS as monotherapy or in combination with ribavirin (Copegus), to patients with chronic hepatitis C (CHC) who have participated in a previous Roche or Roche partner protocol where access to treatment or re-treatment was promised or deemed appropriate following completion of the original protocol ('donor' protocol). Patients who qualify for treatment or re-treatment will begin PEGASYS monotherapy, at a maximum dose of 180 µg weekly, or combination therapy with Copegus, 800-1200 mg daily, as continuation of treatment after the wash-out period defined in their donor protocol. PEGASYS treatment is not to exceed the approved treatment duration of 48 weeks in genotype G1 with a treatment-free follow up period of 24 weeks.
The purpose of this study is to evaluate the safety, immunogenicity, and antiviral effects of multiple intravenous doses of ANZ-521 in patients with chronic Hepatitis C virus.
SCH 900518 is a potent oral inhibitor of HCV NS3 protease which disrupts hepatitis C virus (HCV) polyprotein processing. SCH 900518, when added to the current standard of care (SOC), peginterferon-alfa plus ribavirin, would likely increase the proportion of patients achieving undetectable HCV-RNA levels and sustained virologic response (SVR). In this study, SCH 900518 would be used in combination with low doses of ritonavir to enhance the levels of SCH 900518 within the body and reduce the number of daily SCH 900518 tablets required. The purpose of this study is to identify the optimal dose and schedule (once or twice a day) of SCH 900518 plus ritonavir in previously untreated patients with genotype 1 chronic hepatitis C when given in combination with SOC. The study compares SOC to 6 experimental arms. In the experimental arms, SOC plus SCH 900518 doses of 200, 400 and 600 mg once daily or 100 mg twice daily with ritonavir 100 mg once or twice daily will be explored. The benefits of a 4 week lead-in with PegIntron and ribavirin prior to the addition of SCH 900518 will also be explored.
The main purpose of this study is to determine whether psychological intervention is effective in improving quality of life, mood, and relationships among adults with hepatitis C virus and cirrhosis awaiting liver transplantation.
The purpose of this study is to evaluate the effects of a brief motivational intervention in reducing risky injection practices among injecting drug users (IDUs). The investigators hypothesis is that motivational intervention will be more effective than educational intervention in reducing risky injection practices among IDUs.
This study will investigate safety, antiviral activity, and pharmacokinetics of BI 201335 NA in HCV genotype 1 infected patients treated for 14 days monotherapy followed by BI 201335 NA combination therapy with PegIFN/RBV for an additional 14 days for treatment-naïve patients; or for 28 days as BI 201335 NA combination therapy with PegIFN/RBV for treatment-experienced patients. A secondary objective is to investigate antiviral activity, potential drug-drug interactions and safety of combination therapy of BI 201335 NA and PegIFN/RBV up to 28 days for treatment-naïve patients.
This trial will test the hypothesis that CF102 can safely and effectively suppress viral load in patients with chronic hepatitis C and high circulating levels of virus. The trial will monitor the safety of twice-daily oral dosing with CF102 over a 16-week period; will measure changes in viral load during therapy; and will measure blood concentrations of CF102 at various time points during dosing.
Patients with HCV infection often suffer from chronic fatigue, depression and reduced cognition, even before evolving severe liver fibrosis, liver cirrhosis and hepatic encephalopathy. It is currently unclear to what extent the symptoms er due to a direct pathological effects of the virus itself, or due to pre-existing psychiatric disease. There is a complex relationship between prior or existing drug abuse, psychiatric disease and HCV infection, that makes it difficult to establish cause-effect relationships. A biological mechanism has been suggested to contribute to development of cerebral dysfunction in the patients. According to the prevailing Trojan Horses hypothesis circulating lymphocytes cross the blood brain barrier carrying HCV to the central nervous system and virus is subsequently replicated in the macrophages and the microglia in brain as a separate compartment. As part of the immunological response to viral replication, neurodegenerative processes takes place with a harmful effect on the neural circuit and cerebral function. Identification of HCV RNA negative strand, a replication product, in brain tissue from HCV patients, as part of autopsy studies, supports the hypothesis. Moreover, HCV patients have also been observed with abnormal metabolic concentrations in the frontal white substance and the basal ganglia by MRI spectroscopy compared to control groups. The overall study objective is to assess cerebral function with particular emphasis on cognitive functions in HCV patients (genotypes 1,2,3 and 4) by use of a neuropsychiatric test battery. Furthermore, the patients will be examined by MRI, including magnetization transfer, diffusion tensor and contrast perfusion, in order to perform measurements of cerebral volumetric and microstructure. Finally, HCV analysis, including viral sequences and cytokine profiles, in serum and cerebrospinal fluid will be carried out in the study population.
In patients with chronic hepatitis C, the ultimate treatment goal is the improvement of liver histology and inhibition of progression to liver cirrhosis and hepatocellular carcinoma (HCC). These effects are reported to be correlated with sustained ALT improvement. Therefore, the aim of this study is to determine if a low-dose (0.25, 0.5, or 1.0 mcg/kg SC QW) PegIntron monotherapy administered for 12 weeks will result in ALT normalization in Japanese patients with chronic hepatitis C.
The purpose of this study is to investigate the safety, tolerability, and antiviral activity of ANA598 in patients with genotype-1 chronic hepatitis C infection.
