Filter by:This study will assess the efficacy of boceprevir (BOC) in combination with PegIntron (pegylated interferon alfa-2b) (PEG) and ribavirin (RBV) in response guided therapy compared to the efficacy of standard-of-care therapy alone in adult subjects with chronic hepatitis C (CHC) genotype 1 who failed prior treatment with pegylated interferon and RBV in the Asia Pacific population. The primary hypothesis is that the proportion of participants achieving sustained virologic response in the experimental therapy regimen (BOC/PEG+RBV) is superior to that in the control arm (Placebo/PEG+RBV), in the Full Analysis Set (FAS) population.
The purpose of this study is to compare the rates of sustained virologic response in each cohort (Black-African Americans, Latinos) in this study to historical rate.
This is a proof of concept study, designed to look at the safety and antiviral activity of LCQ908 in hepatitis C infected patients.
Antiviral treatment on Chronic Hepatitis B (CHB) patients with liver cirrhosis is compulsory and effective. Telbivudine, which is superior to lamivudine in the treatment of CHB,is considered to be appropriate for the antiviral treatment on CHB patients with liver cirrhosis.
The purpose of this study is to evaluate the efficacy and safety following the Roadmap Concept strategy with an initial monotherapy using either telbivudine or tenofovir in HBeAg negative CHB patients. The data from the study should allow for the validation of the Roadmap concept in a prospective manner, for both telbivudine and tenofovir treated HBeAg negative CHB patients. As part of a post-approval commitment to the European Health Authorities, the data will also be used to provide an optimized clinical treatment strategy for better clinical use of telbivudine in European HBeAg negative patients. Furthermore, the data from the study will contribute to a better scientific understanding, disease management and treatment of HBeAg negative CHB patients.
The general objective of the present clinical trial is to compare the therapeutic efficacy of a combination therapeutic vaccine containing hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg) [later called NASVAC] with a commonly used antiviral drug, pegylated interferon in patients with chronic hepatitis B (CHB).
This study intends to investigate whether addition of PEG-IFN alfa-2a in HBeAg-negative chronic hepatitis B patients who are pretreated with nucleos(t)ide analogues enhances the degree of HBsAg decline.
This is a Phase 2b, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating Response Guided Therapy using Combinations of Oral Antivirals (GS-5885, tegobuvir, and/or GS-9451) with Peginterferon Alfa 2a and Ribavirin in Treatment Experienced Subjects with Chronic Genotype 1 Hepatitis C Virus (HCV) Infection.
The purpose of this study is to evaluate the safety, tolerability, and efficacy of vaniprevir given in combination with pegylated interferon alfa-2b (peg-IFN) and ribavirin (RBV) versus treatment with peg-IFN and RBV alone in Japanese treatment-naïve participants with chronic hepatitis C (CHC) genotype (GT)1. The primary efficacy hypothesis is that the percentage of participants achieving sustained virologic response 24 weeks after completion of all study therapy (SVR24) in at least one of the vaniprevir arms is superior to the percentage of participants achieving SVR24 in the control arm.
This clinical trial compares the efficacy of peginterferon plus tenofovir for 24 weeks followed by monotherapy with tenofovir for a further 3.5 years to the efficacy of tenofovir alone given for 4 years in patients with chronic hepatitis B. The primary measure of outcome will be HBsAg loss in serum at 48 weeks after stopping all antiviral therapy (sustained off-treatment response).
