Active clinical trials for "Hepatitis A"

The purpose of this study is to determine if nitazoxanide in combination with peginterferon alfa-2a and ribavirin is safe and effective in treating chronic hepatitis C in treatment-naive patients.

This is a multicentre, multinational clinical study. It comprised two consecutive segments (A and B). Segment A was designed as a randomized, double-blind, double-dummy, active-controlled, two-arm parallel-group study. The patients received either budesonide or prednisone for 6 months. During segment B all patients received budesonide as an open treatment for additional 6 months. In this confirmatory study the proportion of patients with complete response was compared between the two treatment groups. Complete response was defined as biochemical remission (=serum levels of ASAT and ALAT within normal ranges) at the individual last visit of segment A and lack of steroid specific side effects throughout segment A.

This is a proof-of-concept study which will provide data about the safety and antiviral activity of several doses of the investigational drug IDX184 given for 3 days in treatment-naive HCV genotype 1-infected subjects so that optimal doses can be chosen for testing in later studies.

This study will evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of albinterferon alfa 2b (alb-IFN) single dose in Japanese chronic hepatitis C patients

The purpose of this study is to further assess the potency of PF-00868554, an HCV polymerase inhibitor, in subjects chronically infected with HCV by evaluating the antiviral activity of PF-00868554 in combination with current standard of care therapy, pegylated interferon-alpha2a (PEGASYS) and ribavirin (COPEGUS).

The influence of insulin sensitivity and glucose tolerance on the effects of antiviral therapy for HCV remains unclear. The aim of the present study was (1) To elucidate the clinical and virological factors associated with sustained viral response in patients with combination therapy with PEG-IFN and ribavirin. (2) To clarify the influence of diabetes mellitus (DM), impaired glucose tolerance test (IGT) and insulin resistance (IR) on the HCV response to combination therapy with PEG-IFN and ribavirin. (3) To test the influence of combination therapy on HOMA IR

The objective is to evaluate the efficacy and safety of the combination therapy with subcutaneous (SC) Pegylated Interferon (PEG-IFN) alfa-2b 1.5 ug/kg/week plus low-dose ribavirin administered for 48 weeks in participants with chronic hepatitis C virus (HCV) who are infected with HCV genotype 1 high viral load, and weigh 50 kg or less.

This study will explore efficacy and safety of Telbivudine in the fifth year of treatment.

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 purpose of this 12-week study was to assess in subjects with chronic hepatitis C (treatment-naïve, genotype 1) receiving weight-based doses of ribavirin the early virologic response to the 480 ug dose level of Locteron™, dosed every 2 weeks, in comparison with 1.5 ug/kg PEG-Intron™ dosed weekly.
