Filter by: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.
This randomized, single-center, controlled study is designed to evaluate the safety, tolerability, and efficacy of treatment with Peg-Intron with Rebetol in methadone or buprenorphine maintenance patients with hepatitis C.
Genotype 4 is the least-studied hepatitis C virus genotype and was considered a difficult to treat genotype due to the disappointing response of chronic hepatitis C genotype 4 to conventional interferon monotherapy. Recent reports showed that pegylated interferon and ribavirin combination therapy markedly increased the SVR rate to 55-70%. The duration of treatment has not been accurately defined. The main objective of this is to assess the duration of pegylated interferon ribavirin therapy in chronic hepatitis genotype 4 and assess the clinical utility of rapid and early virologic response in determining the optimal duration of peg interferon ribavirin therapy in chronic hepatitis C.
This is a treatment study trial, in which we will assess the safety and tolerability of daily dose IL-2, as monotherapy for 12 weeks, followed by IL2 in combination with PEG-IFN and RBV for 48 weeks in the treatment of chronic Hepatitis C.
The purpose of this study is to determine the efficacy and tolerability of CPG 10101 at two different dose levels with pegylated-interferon-alpha 2B (PEG-IFN) plus ribavirin (RBV) compared to PEG-IFN and RBV without CPG 10101 in HCV positive subjects who were classified as non-responders to previous adequate PEG-IFN plus RBV therapy.
The study is being done to study the impact of prophylactic administration of antiviral therapy as compared to initiation of antiviral therapy at the time of clinical recurrence of hepatitis C infection in liver transplant recipients.
To study the effectiveness and safety of adding Rosiglitazone, an insulin sensitizing agent to people with chronic hepatitis C infection genotype 1 with fatty liver disease, who are being treated with standard therapy. Standard therapy consists of weekly pegylated interferon injections and daily ribavirin pills, whose dosage is weight based. This regimen in genotype 1 patients is effective in only 45% of patients at best. In addition, this therapy must be given for 48 weeks to be effective and has alot of side-effects. One risk factor for a poor response is fatty liver. Rosiglitazone has been shown to be effective in the treatment of patients with fatty liver alone. This study hopes to show that the addition of Rosiglitazone to the standard therapy in genotype 1 patients with fatty liver disease will increase effectiveness of the standard therapy of hepatitis C.
We conducted a randomized controlled trial of adjuvant interferon (IFN) therapy in patients with hepatitis-C virus (HCV)-related cirrhosis who underwent curative resection of hepatocellular carcinoma (HCC) to investigate whether IFN could reduce or delay the incidence of recurrent tumor (secondary/tertiary prevention of HCC). Patients were randomly assigned to treatment with IFN (3MU thrice/wk /48 weeks) vs. no treatment after curative resection of HCC(control group)
We hypothesized that pretreatment nonresponder and responder liver tissue would show consistent differences in gene expression levels and that these differences could be used to predict treatment outcomes and this can obviate the need of the present therapeutic trial.We are interested in conducting a retrospective study using the data of patients suffering from chronic HCV infection who were treated in our department with a combination of PEGINTERFERON and RIBAVIRIN. All these patients underwent liver biopsy prior the treatment. Based on the clinical data available it is possible to determine the responders and nonresponders to this therapy.RNA will be extracted from the liver tissue and the expression of 5 genes(IFI15,IFI616,IFI1,OAS3,OAS2 )will be checked .The prediction power of the combination of these genes in differentiating responders from nonresponders will be determined.
The main purpose of this study is to evaluate the safety and tolerability of combination therapy of daily interferon alfacon-1 (Infergen, CIFN) at high dosage (24 mcg) with ribavirin (based on body weight) for 48 weeks in HCV genotype 1 infected subjects, who are non-responders to previous pegylated interferon alfa plus ribavirin therapy. This is an open-label, multicenter study. All subjects will receive Infergen 24 mcg administered by injection daily plus ribavirin 800-1400 mg (based on body weight) administered by mouth daily for 48 weeks * If any 5 of the first 10 subjects can not tolerate the 24 mcg daily dosage of Infergen by week 4, as determined by the principal investigator, then the dosage of Infergen will be changed to 15 mcg administered by injection daily plus ribavirin 800-1400 mg (based on body weight) administered by mouth daily for 48 weeks
