NCT ID: NCT00227435 Completed - Chronic Hepatitis C Clinical Trials

Dose Escalation Study to Evaluate the Safety and Antiviral Activity of Val-mCyd in Adults With Chronic Hepatitis C

Start date: February 2003
Phase: Phase 1/Phase 2
Study type: Interventional

This study was conducted to determine the safety, tolerance, pharmacokinetics and antiviral activity of val-mCyd at doses ranging from 50 mg to 800 mg per day.

NCT ID: NCT00227149 Completed - Clinical trials for Hepatitis C, Chronic

Long-Term Evaluation Follow-up of Neurocognitive Performance and Emotional State in Patients With Chronic Hepatitis C

Start date: July 2005
Phase: N/A
Study type: Observational

This is a long-term evaluation follow-up study of neurocognitive performance and emotional state in patients with chronic hepatitis C infection and a former (peg)interferon alfa-2b-based therapy. M.R. Kraus, G. Teuber, NN, NN (MPsych), M. Scheurlen Questions: - Neurocognitive and psychiatric changes induced by interferon alfa-2b therapy in patients with chronic hepatitis C - are they fully reversible in long-term follow-up after the end of antiviral treatment? - At least 12 months after the end of antiviral treatment - are neurocognitive and mood-related parameters even significantly improved as compared to pretreatment values? Is this possibly only true of patients with successful virus eradication? - At least 12 months after the end of antiviral treatment, is there a significant difference between patients with and without sustained virological response with respect to neurocognitive performance, emotional state and quality of life? - In the absence of clinically significant liver damage in patients with chronic hepatitis C - does the mere presence of the hepatitis C virus have any significant influence on neurocognitive or attentional performance? - Does the study data support an additional indication for antiviral therapy in chronic hepatitis C? In the case of successful virus eradication, emotional state and - above all - is neurocognitive performance significantly improved even in the absence of severe liver damage?

NCT ID: NCT00225537 Active, not recruiting - Chronic Hepatitis B Clinical Trials

4-Methylumbelliferone as a Treatment for Chronic HBV/HCV

Start date: September 2005
Phase: Phase 2
Study type: Interventional

Open-label studies, anecdotal reports, and in vitro scientific research indicate that 4-methylumbelliferone (active ingredient of the dietary supplement Heparvit®) may prevent and reverse the symptoms and complications of chronic infection with hepatitis B virus (HBV)and hepatitis C virus (HCV). This effect has been observed among naïve patients as well as those who are non-responders to interferon, commonly used as first-line therapy for HBV and HCV. In order to scientifically address the efficacy of this 4-methylumbelliferone on chronic viral hepatitis, a randomized, placebo-controlled, blinded study is needed. It is hypothesized that 4-methylumbelliferone may reduce the impact and aggressiveness of HBV and HCV upon the liver, thereby slowing the progression to potentially life threatening liver diseases such as cancer and cirrhosis. This is a preliminary study designed to determine any indications under controlled conditions that may warrant further detailed clinical studies.

NCT ID: NCT00221650 Completed - HIV Infections Clinical Trials

Treatment of Chronic Hepatitis C With PEG Interferon alfa2a and Ribavirin in HIV-Infected Patients

ROCO2
Start date: April 2002
Phase: Phase 2
Study type: Interventional

Combination of PEG interferon and ribavirin is the standard treatment of chronic hepatitis C. Efficacy of this treatment has never been evaluated in HCV-HIV infected patients, who have previously been treated with a first line anti-HCV treatment. The purpose of the study is to evaluate the combination PEG interferon alfa2a-ribavirin in HIV-infected patients with chronic hepatitis C pretreated with interferon alone or interferon combined with ribavirin. The patients receive a dose of 180 µg of PEGASYS once a week and 800 to 1200 mg/day of ribavirin (according to weight) for 48 weeks. Primary outcome of the study is a sustained virological response, defined as an undetectable HCV RNA level 24 weeks after the end of anti-HCV treatment.

NCT ID: NCT00221624 Completed - Clinical trials for Hepatitis C, Chronic

Peginterferon Alfa-2a Plus Ribavirin Plus Amantadine for the Treatment of Hepatitis C Infected Patients

PEGARI
Start date: November 2001
Phase: Phase 3
Study type: Interventional

Response to a second-line anti-HCV treatment in non responder patients to a first-line dual therapy remains very poor. Preliminary studies of amantadine suggest that this drug could be potentially effective to treat hepatitis C.

NCT ID: NCT00219999 Completed - Hepatitis C Virus Clinical Trials

Hepatitis C Virus and the Humoral Immune System

Start date: September 2001
Phase: N/A
Study type: Observational

The purpose of this study is to measure specific chemokines, antibodies, and antibody-producing B cells in the blood of patients with hepatitis C virus (HCV) infection. Our hypothesis is that changes in chemokine levels affect the development of an effective immune response against HCV.

NCT ID: NCT00218556 Completed - Hepatitis C Clinical Trials

Preventing Depression in Methadone Maintenance Patients Receiving Hepatitis C Treatment - 1

Start date: January 2004
Phase: N/A
Study type: Interventional

The purpose of this study is develop and test a cognitive-behavioral intervention to prevent depression in methadone maintenance patients receiving medical treatment for hepatitis C.

NCT ID: NCT00218192 Completed - HCV Risk Behavior Clinical Trials

A Trial to Reduce Hepatitis C Among Injection Drug Users - 1

Start date: September 2000
Phase: Phase 3
Study type: Interventional

The purpose of this study is to examine the efficacy of a brief motivational intervention on the cumulative incidence of Hepatitis C.

NCT ID: NCT00217139 Completed - Clinical trials for Hepatitis C, Chronic

A Study to Evaluate the Safety and Efficacy of Celgosivir and Peginterferon Alfa-2b, With or Without Ribavirin, in Patients With Chronic Hepatitis C Genotype 1 Infection

Start date: September 2005
Phase: Phase 2
Study type: Interventional

The objective of the study is to evaluate the safety and efficacy of celgosivir plus peginterferon alfa-2b, with or without ribavirin, for 12 weeks in patients with chronic hepatitis C genotype 1 infection.

NCT ID: NCT00216775 Completed - Clinical trials for Hepatitis C, Chronic

Comparative Trial of Standard Versus Low-dose Peg-Interferon Plus Ribavirin in the Treatment of Chronic Hepatitis C

Start date: December 2004
Phase: Phase 4
Study type: Observational

The purpose of this study is to evaluate the efficacy and safety of low-dose interferon-alfa-2b plus ribavirin compared to the standard-dose of the same combination in patients with chronic hepatitis C.
