NCT ID: NCT01671046 Completed - Clinical trials for Hepatitis C, Chronic

An Observational Study To Assess Liver Fibrosis Stages in Patients With Chronic Hepatitis C Infection

Start date: July 2012
Phase: N/A
Study type: Observational

This multi-center, prospective observational study will evaluate the correlation of liver biopsy and transient elastography in liver fibrosis assessment in patients with chronic hepatitis C. Data will be collected for 96 weeks.

NCT ID: NCT01667731 Completed - Hepatitis C Clinical Trials

Efficacy and Safety of Sofosbuvir Plus Ribavirin in Chronic Genotype 1, 2 and 3 Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV) Co-infected Adults

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

This study will evaluate the efficacy, safety, and tolerability of sofosbuvir (SOF; GS-7977) plus ribavirin (RBV) in adults with chronic genotypes 1, 2, and 3 HCV infection who are coinfected with HIV-1.

NCT ID: NCT01667081 Completed - Hepatitis C Clinical Trials

Durability of Virologic Response and/or Viral Resistance Patterns in Participants With Chronic Hepatitis C Who Have Been Previously Treated With Grazoprevir (MK-5172) (MK-5172-017)

Start date: October 17, 2012
Phase:
Study type: Observational

This is a three-year (except for participants with chronic kidney disease [CKD] or cirrhosis) multicenter study to follow participants who received at least one dose of grazoprevir (MK-5172) in a previous study to determine whether they remain hepatitis C virus (HCV)-Ribonucleic acid (RNA) negative over time, and to determine if they have developed antiviral resistance. The study will also evaluate long-term adverse events in this population. Participants from MK-5172-052 (NCT02092350) with CKD or cirrhosis will be followed for five years.

NCT ID: NCT01663922 Completed - Hepatitis C Clinical Trials

Boceprevir and Ucalm (St John&Apos;s Wort)

Start date: August 2012
Phase: Phase 1
Study type: Interventional

The purpose of the study is to look at whether taking a new medication for hepatitis C (boceprevir) together with a herbal remedy commonly used for the treatment of depression (SJW) has any effect on the levels of boceprevir in the blood, compared to when boceprevir is taken on its own. Treatment of hepatitis C genotype-1, has recently been significantly improved with the addition of a new class of drugs called protease inhibitors (PIs). Boceprevir belongs to this class of antiviral drugs and it is administered in combinations with other drugs to treat hepatitis C. One of the common side effects of treatment for hepatitis C is low mood (depression) for which treated patients may self-medicate with preparations containing St. Johns Wort (SJW). SJW is known to cause drug interactions, so taking SJW at the same time as boceprevir may result in a change in how both of these drugs usually work. It is therefore important to find out if the levels of boceprevir in the blood are significantly affected by taking SJW. The study aims to help us understand whether it will be safe to take SJW whilst being simultaneously treated for hepatitis C with boceprevir.

NCT ID: NCT01659567 Completed - Clinical trials for Hepatitis C, Chronic

A Study of Predictors of the Effectiveness of Pegylated Interferon in a Cohort of Participants With Hepatitis C

Start date: April 6, 2011
Phase: N/A
Study type: Observational

This prospective observational study will investigate predictive values of virological response in pegylated interferon alfa-2a (Pegasys)/ribavirin (Copegus) treatment-naive participants with chronic hepatitis C. Participants will be treated with pegylated interferon alfa-2a and ribavirin as prescribed by the physician. Data will be collected for a maximum of 96 weeks.

NCT ID: NCT01648140 Completed - Clinical trials for Hepatitis C, Chronic

Dose Ranging of GSK2336805 in Combination Therapy

HAI115879
Start date: August 2012
Phase: Phase 2
Study type: Interventional

GSK2336805 is a novel hepatitis C virus (HCV) non-structural 5A (NS5A) inhibitor being developed for the treatment of chronic HCV infection. This Phase II, multicenter, parallel-group, randomized, dose-ranging study will assess the safety and tolerability, antiviral activity, and pharmacokinetics of GSK2336805 at 2 dose levels (40 and 60 mg) in combination with pegylated interferon alfa-2a (PEG) and ribavirin (RIBA) in approximately 100 treatment-naïve subjects with chronic genotype 1 HCV infection. In a separate nonrandomized single-arm cohort, up to 15 treatment-naïve subjects with genotype 4 chronic HCV infection will be enrolled in parallel at the dose level of 60 mg of GSK2336805.

NCT ID: NCT01647191 Completed - Hepatitis C Clinical Trials

Reducing Hepatitis C Virus (HCV)/Human Immunodeficient Virus (HIV) Risk Behaviors Among Injection Drug Users in China

Start date: July 1, 2011
Phase: N/A
Study type: Interventional

The proposed study will investigate the knowledge level, attitudes, and perceptions among staff of Methadone Maintenance Treatment (MMT) clinics and intravenous drug users (IDUs) who attending MMT clinics, which is the most reachable population for HCV/HIV intervention in China. This study will also explore the barriers that prevent IDUs from getting HCV/HIV intervention/prevention and medical care services. This study will help to understand and address this important problem in China and other Asian countries.

NCT ID: NCT01646489 Completed - Hepatitis C Clinical Trials

Drug Interaction Study to Assess the Effect of Co-Administered Miravirsen and Telaprevir in Healthy Subjects

Start date: June 2012
Phase: Phase 1
Study type: Interventional

The purpose of this study is to assess the safety, tolerability, and affect on blood levels of miravirsen and telaprevir when administered together.

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: NCT01637922 Completed - Hepatitis C Clinical Trials

Drug Interaction Study With BI 201335 and Methadone or Buprenorphine/Naloxone

Start date: August 2012
Phase: Phase 1
Study type: Interventional

Otherwise healthy subjects who are currently bein maintained on either methadone or buprenorphine/naloxone for opioid maintenance therapy who have been on a stable dose for at least 30 days will be administered BI 201335 daily to determine if a drug interaction occurs between BI 201335 and either methadone or buprenorphine/naloxone.
