NCT00245414
The purpose of this study is to investigate the efficacy and safety of Pegasys® 180μg for subcutaneous (s.c.) injection in interferon (IFN)-treated or IFN-untreated chronic hepatitis C patients except for those infected with genotype 1b of hepatitis C virus (HCV) and a high viral load (≥ 100 KIU/mL). In addition, this study will explore the efficacy and safety of Pegasys® 180μg for s.c. injection given at 2 different periods between 24 and 48 weeks in IFN-untreated chronic hepatitis C patients.
NCT00281502
The study will be conducted in two phases. Phase A will evaluate the contribution of bacterial overgrowth and colonic inertia to development of Hepatic Encephalopathy (HE)in 50 ambulatory subjects with HE and hepatitis C cirrhosis. This phase will include a Screening and Evaluation Visit. Phase B will evaluate the effect of rifaximin on bacterial outgrowth and severity of HE in 20 of the subjects enrolled in Phase A who have a somewhat greater degree of encephalopathy. The purpose of this study is to evaluate the following: 1. the relationship between bacterial overgrowth and the presence and severity of HE in patients with hepatitis C cirrhosis; 2. the effectiveness and tolerability of rifaximin relative to placebo in treatment of HE associated with hepatitis C cirrhosis; 3. the relationship between bacterial overgrowth and the presence and severity of HE before and after rifaximin treatment.
NCT00310336
50-60% of patients with chronic hepatitis C are not cured by treatment with pegylated IFNα plus ribavirin. Retreatment of non-responders of previous (pegylated) IFNα plus ribavirin therapies with pegylated IFNα plus ribavirin results in a sustained response in less than 10% of the patients. Extensive analysis of IFNα signaling in cells expressing HCV proteins, in transgenic mice expressing HCV proteins, and in liver biopsies from patients with chronic hepatitis C point to STAT1 methylation as an important posttranslational modification targeted by HCV to inhibit IFNα signaling. STAT1 methylation can be increased and IFNα can be improved by adding AdoMet and betaine. The study is designed to test the hypothesis that a combination treatment with pegylated IFNα2b, ribavirin, AdoMet and betaine is superior to the current standard combination therapy with pegylated IFNα plus ribavirin.
