NCT ID: NCT01641094 Completed - Chronic Hepatitis C Clinical Trials

Effect of Teleprevir in Triple Therapy on Intrahepatic Immunological Mechanisms

ETIM
Start date: May 2012
Phase: N/A
Study type: Observational

Chronic hepatitis C infection (HCV) is a disease that affects worldwide about 170 million people. The previous standard of care therapy of chronic HCV patients consists of pegylated-IFN-α combined with ribavirin, and results in sustained clearance of HCV-RNA in only about 50% of the HCV genotype 1 infected patients. Telaprevir, a NS3A-4A inhibitor, has previously proven to offer therapeutic options to previous non-responders to the standard of care. Although, not all chronic HCV patients benefit from telaprevir and it is still not known why certain patients are also non-responsive to this triple therapy. In this study we try to understand why certain patients are also non-responsive to telaprevir, how triple therapy modulates the responsiveness to IFN-α and what the immunological consequences are of treatment with telaprevir, either directly or as a result of telaprevir-induced reduction of HCV-RNA levels.

NCT ID: NCT01634919 Completed - Chronic Hepatitis C Clinical Trials

Histologic Changes and Noninvasive Assessment in Hepatitis C Patients Treated With Peginterferon Alpha-2a and Ribavirin

Start date: July 2012
Phase:
Study type: Observational

•The purpose of this study is to compare the performance between liver biopsy and non-invasive fibrosis assessments evaluating anti-fibrotic efficacy of peginterferon plus ribavirin in patients with hepatitis C pre- and post-treatment

NCT ID: NCT01625338 Completed - Chronic Hepatitis C Clinical Trials

Open-Label Study of Sofusbuvir+Ribavirin With or Without Peginterferon Alfa-2a in Subjects With Chronic HCV Infection Who Participated in Prior Gilead HCV Studies

Start date: June 2012
Phase: Phase 3
Study type: Interventional

This study will evaluate the efficacy, safety, and tolerability of sofosbuvir (SOF; GS-7977) in combination with ribavirin (RBV) with or without pegylated interferon (Peg-IFN) in adults with chronic hepatitis C virus (HCV) infection who participated in a prior Gilead HCV study and have not achieved sustained virologic response (SVR).

NCT ID: NCT01609933 Completed - Chronic Hepatitis C Clinical Trials

A Study to Evaluate the Safety and Effect of Treatment With Experimental Antiviral Drugs in Combination With Peginterferon Alpha-2a and Ribavirin in People With Hepatitis C Virus Who Did Not Respond to Treatment in a Previous AbbVie/Abbott Combination Study

Start date: December 18, 2012
Phase: Phase 2
Study type: Interventional

A study to evaluate the safety and effect of treatment with experimental antiviral drugs in combination with peginterferon alpha-2a and ribavirin in people with hepatitis C virus who did not respond to treatment in a previous AbbVie/Abbott combination study.

NCT ID: NCT01604850 Completed - Chronic Hepatitis C Clinical Trials

Sofosbuvir + Ribavirin for 12 or 16 Weeks in Treatment Experienced Subjects With Chronic Genotype 2 or 3 HCV Infection (FUSION)

FUSION
Start date: June 2012
Phase: Phase 3
Study type: Interventional

This study was to assess the safety and efficacy of sofosbuvir in combination with ribavirin (RBV) administered for 12 or 16 weeks in participants with genotypes 2 or 3 hepatitis C virus (HCV) infection as assessed by the proportion of participants with sustained virologic response (SVR) 12 weeks after discontinuation of therapy (SVR12).

NCT ID: NCT01596517 Completed - Chronic Hepatitis C Clinical Trials

Efficacy and Effectiveness of PegInterferon and Ribavirin in Korean Patients With Chronic Hepatitis C

Start date: June 2003
Phase: Phase 4
Study type: Interventional

The purpose of this study is to investigate the efficacy and effectiveness of peginterferon alfa-2a and ribavirin therapy in Korean chronic hepatitis C patients.

NCT ID: NCT01581398 Completed - Chronic Hepatitis C Clinical Trials

Efficacy and Safety Study of Peginterferon Alfa-2b in Chinese Chronic Hepatitis C Patients

Start date: April 2012
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the efficacy and safety of Peginterferon alfa-2b (40KD, Y shape, the followings will refer as Ypeginterferon alfa-2b for short), at a dose of 180μg/week, in combination with Ribavirin in Chinese chronic hepatitis C patients. The study will first group patients into two sub-study, genotype 2/3 and non-genotype 2/3, depending on the HCV genotype that infected. In the genotype 2/3 sub-study about 219 patients will be enrolled, and eligible patients are randomized at 2:1 ratio into Ypeginterferon alfa-2b group or active control group (Pegasys), receiving 24 weeks of interferon therapy and oral daily Ribavirin at a dose of 800mg/d. In the non-genotype 2/3 sub-study about 507 patients will be enrolled, and eligible patients are randomized at 2:1 ratio into Ypeginterferon alfa-2b group or active control group (Pegasys), receiving 48 weeks of interferon therapy and oral daily Ribavirin 1000-1200mg/day , basing on body weight. All patients will be followed for 24 weeks after the end of therapy.

NCT ID: NCT01577069 Completed - Chronic Hepatitis C Clinical Trials

Predictive Factors of the Treatment Failure in Hepatitis C Virus (HCV) Infected Patients Treated With Telaprevir

GENUPI
Start date: February 2011
Phase: N/A
Study type: Observational

The purpose of the study is to 1- detect and quantify HCV-PI resistant mutants with ultra-deep pyrosequencing (UDPS) technology, 2 - detect SNPs in P-glyocoprotein and CYP3A genes, in HCV mono-infected patients under/after Telaprevir treatment.

NCT ID: NCT01571583 Completed - Clinical trials for Chronic Hepatitis C Virus (HCV) Infection

An Efficacy and Safety Study of Telaprevir in Patients With Genotype 1 Hepatitis C Infection After Liver Transplantation

REPLACE
Start date: February 2012
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the effectiveness of telaprevir in combination with Peg-IFN-alfa-2a and ribavirin in stable liver transplant patients with chronic hepatitis C virus (HCV) genotype 1.

NCT ID: NCT01542788 Completed - Chronic Hepatitis C Clinical Trials

Sofosbuvir + Ribavirin for 12 Weeks in Subjects With Chronic Genotype 2 or 3 Hepatitis C Infection Who Are Interferon Intolerant, Interferon Ineligible or Unwilling to Take Interferon

POSITRON
Start date: March 2012
Phase: Phase 3
Study type: Interventional

This multicenter study was to evaluate subjects with chronic genotype 2 or 3 HCV infection who were interferon (IFN) ineligible, IFN intolerant or unwilling to take IFN. Participants were randomized in a 3:1 ratio to receive sofosbuvir (SOF)+ribavirin (RBV), or placebo to match SOF+placebo to match RBV. Randomization was stratified by presence/absence of cirrhosis. Approximately 20% of participants may have had evidence of cirrhosis at screening.
