NCT ID: NCT01547312 Withdrawn - Chronic Hepatitis C Clinical Trials

Evaluation of Hepatic Pharmacokinetics for Grazoprevir (MK-5172) in Participants With Chronic Hepatitis C (MK-5172-022)

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

This study is divided into 2 segments, and proposes to qualify fine needle aspiration (FNA) as a platform to evaluate the hepatic pharmacokinetics of low and high oral doses of Grazoprevir (MK-5172) in non-cirrhotic participants chronically infected with hepatitis C virus (HCV). The first segment, is a procedural pilot conducted prior to the main study, that is aimed at ensuring optimal execution of the FNA procedure. During the procedural pilot, core needle biopsy (CNB) will be performed on participants as part of their standard of care, but no study drugs will be administered, nor will any procedures other than FNA be conducted. The second segment, the main study, is designed to evaluate the feasibility of measuring Grazoprevir by FNA. During the main study, drugs will be administered, and other additional procedures will be conducted.

NCT ID: NCT01525212 Withdrawn - Chronic Hepatitis C Clinical Trials

Multiple Ascending Dose Study of BMS-929075 in Hepatitis C Virus (HCV) Infected Patients

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

The purpose of this study is to determine the change from baseline in HCV Ribonucleic acid (RNA) on Day 4 following three days of dosing with BMS-929075 in chronically genotype subtype 1a and 1b HCV infected subjects

NCT ID: NCT01517308 Withdrawn - Chronic Hepatitis C Clinical Trials

24 VS 48-WEEK TREATMENT WITH PEG-IFN ALPHA-2A IN PATIENTS WITH GENOTYPE 2/3 CHRONIC HEPATITIS C

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

Aim of the present study is to evaluate in a cohort of patients with genotype 2/3 chronic hepatitis C, relapsers to a previous PEG-IFN + ribavirin therapy (alpha-2a or alpha-2b) the efficacy of PEG-IFNα-2a + ribavirin administered for 24 or 48 weeks. It will be evaluated whether 48 weeks of therapy may achieve better results compared to the standard duration (24 weeks).

NCT ID: NCT01274013 Withdrawn - Chronic Hepatitis C Clinical Trials

Vitamin D Deficiency in Subjects With Chronic Hepatitis C Compared to Healthy Volunteers

Start date: October 2009
Phase:
Study type: Observational

The objective of this study is to assess the prevalence of vitamin D deficiency in patients with chronic Hepatitis C compared to a matched control group of healthy individuals in the Sioux Falls area. It is the hypothesis of this study that vitamin D deficiency is more common in patients with chronic Hepatitis C compared to the healthy control group.

NCT ID: NCT01142700 Withdrawn - Clinical trials for Chronic Hepatitis C Virus Genotype 1

A Study of BMS-824393 in Combination With Peginterferon Alfa-2a (Pegasys) and Ribavirin (Copegus) in Treatment Naive Subjects With Chronic Hepatitis C Virus Genotype I

Start date: July 2010
Phase: Phase 2
Study type: Interventional

Based on 12-week on-treatment data, at least 1 dose of BMS-824393 can be identified which is safe, well tolerated, and has sufficient antiviral activity to progress to late stage clinical trials when combined with pegIFNα/RBV for treatment of chronically infected hepatitis C virus genotype 1 treatment-naive subjects.

NCT ID: NCT00876174 Withdrawn - Chronic Hepatitis C Clinical Trials

Effects of Genotypes on Interferon Signaling in Chronic Hepatitis C

Start date: April 15, 2009
Phase:
Study type: Observational

The objective of this pilot project is to investigate the prognostic criteria for sensitivity of Chronic Hepatitis C (CHC) Genotype 1, patients to IFNa treatment. Signal transduction in peripheral blood mononuclear cell (PBMC) of control groups will be compared with that of CHC patients. For this study, 20 patients with Hepatitis C virus (HCV) infection who are to undergo standard antiviral therapy and 10 healthy donors (significant others of the HCV subject) will be enrolled. Signal transduction will be studied in peripheral blood of CHC subjects before the treatment, after 1 and 3 months of treatment, and 4-6 months following the completion of treatment.

NCT ID: NCT00571714 Withdrawn - Chronic Hepatitis C Clinical Trials

Pilot Comparison of Standard Antiviral Therapy With and Without 12 Weeks of Betaine in Genotype 1 Naive Patients

Start date: April 1, 2008
Phase: N/A
Study type: Interventional

The primary purpose of the study is to compare the safety and effectiveness of standard treatment for chronic hepatitis C using peginterferon alpha-2a (Pegasys) and ribavirin (Copegus) to those same medications plus a dietary supplement called betaine when added for the first 12 weeks of treatment. Peginterferon alpha-2a (Pegasys) and ribavirin (Copegus) are approved by the FDA (Food and Drug Administration) for the treatment of chronic hepatitis C. Betaine is a dietary supplement and occurs naturally in the body. It is not a medication regulated by the FDA or an approved drug for chronic hepatitis C.

NCT ID: NCT00255359 Withdrawn - Clinical trials for Chronic Hepatitis C Virus Infection

Safety, Tolerability and Efficacy of XTL 2125 in HCV-Infected Patients Who Are Interferon-Alpha Non-Responders or Relapsers

Start date: February 2006
Phase: Phase 1
Study type: Interventional

The study will be a randomized, double blind, placebo controlled, dose rising study in Interferon alpha (IFN-alpha) non-responder HCV infected patients or HCV patients who have relapsed following IFN-alpha therapy. Eligible subjects must have compensated liver disease and serum HCV RNA concentrations above 100,000 IU/mL at screening. The study will include both a single dose period for the evaluation of acute toxicity and single dose pharmacokinetics and a consecutive multi-dose period for the determination of longer-term safety, multiple-dose pharmacokinetics and antiviral activity. The objectives of this study are to evaluate the safety, tolerability, and antiviral activity of escalating single and multiple doses of XTL 2125 in patients with chronic hepatitis C virus infection and to assess the single- and multiple-dose pharmacokinetics of XTL 2125
