NCT ID: NCT00230958 Completed - Chronic Hepatitis C Clinical Trials

Study of Viramidine to Ribavirin in Patients With Chronic Hepatitis C Who Are Treatment-Naive

Start date: December 2003
Phase: Phase 3
Study type: Interventional

This purpose of this study is to determine the safety and effectiveness of viramidine to ribavirin in chronic hepatitis C patients who have never before recieved treatment.

NCT ID: NCT00230854 Completed - Chronic Hepatitis C Clinical Trials

Study in Non-responder Hepatitis C Genotype 1 Patients With EMZ702, Pegylated Interferon and Ribavirin

Start date: August 2005
Phase: Phase 1
Study type: Interventional

The purpose of this study is to assess the safety and efficacy of repeated intravenous infusions of EMZ702 in combination with pegylated interferon and ribavirin in patients with chronic hepatitis C genotype 1.

NCT ID: NCT00230503 Completed - Clinical trials for Hepatitis B, Chronic

Dose-Ranging Study of Pradefovir in Patients With Compensated Hepatitis B

Start date: June 2004
Phase: Phase 2
Study type: Interventional

- Compare the safety of four oral doses of pradefovir after 48 weeks of treatment - Select the dose of pradefovir for Phase 3 studies

NCT ID: NCT00230477 Completed - Hepatitis B Clinical Trials

Hepsera Versus Hepsera Plus Lamivudine for Treatment of Chronic Hepatitis B in Patients With Normal ALT

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

This project is a randomized, open-label trial of adefovir dipivoxil (Hepsera) and lamivudine combination therapy versus adefovir dipivoxil (Hepsera) monotherapy. Both adefovir dipivoxil and lamivudine are nucleoside analogues approved by the U.S. FDA for the treatment of chronic hepatitis B. The primary hypothesis is that subjects treated with combination therapy will see their viral DNA count decrease in an amount greater than subjects treated with monotherapy. The secondary hypothesis is that subjects treated with combination therapy will have a higher HBeAg conversion rate compared to historical controls of subjects treated with lamivudine or adefovir dipivoxil monotherapy.

NCT ID: NCT00230061 Completed - HIV Infections Clinical Trials

Hepatitis B Vaccination in HIV-infected Persons

Start date: April 2004
Phase: Phase 4
Study type: Interventional

In this study we compare the efficacy of two different HBV-vaccination schedules in HIV-infected persons concerning immune response and compliance. Short schedule: t=0,1,3 weeks and standard schedule: t=0,1,6 months.

NCT ID: NCT00229580 Completed - Hepatitis C Clinical Trials

Health Behavior Feedback Study for Veterans With Hepatitis C

Start date: December 2003
Phase: Phase 1
Study type: Interventional

The purpose of this study was to explore whether a brief (3 session) intervention would impact health behavior of veterans with hepatitis C. The main focus of the intervention was on reduction of heavy drinking with patients who have liver disease. Other study goals were to increase the likelihood that patients would seek out substance use treatment and/or hepatitis C health care services. The study also tested the use of a liver function test called CDT/GGT in detecting heavy drinking. The main hypothesis was that a 3 session intervention with personalized feedback about health behavior would result in a reduction in alcohol use and increased use of substance use treatment and hepatology health care.

NCT ID: NCT00228917 Completed - Hepatitis B Clinical Trials

Safety Study of Tritanrix-HepB/Hib-MenAC, Tritanrix-HepB/Hiberix, and Mencevax ACWY Vaccines in Children

Start date: June 16, 2005
Phase: Phase 3
Study type: Interventional

This study will be conducted in two stages. In the diphtheria, tetanus, pertussis (DTP) booster phase, subjects will receive a booster dose of Tritanrix-HepB/Hib-MenAC or Tritanrix-HepB/Hiberix (active control) at 15 to 18 or 24 months in a single-blind manner so that the subjects' parents will not know which vaccine was administered to their child. In the Mencevax ACWY phase at 24-30 months, a dose of Mencevax ACWY will be given in an open manner to only those subjects who received less than 4 doses of Tritanrix-HepB/Hib-MenAC. No blood samples will be taken in this safety study.

NCT ID: NCT00228592 Terminated - Hepatitis B Clinical Trials

HepeX-B in Post Hepatic Allografts for Treatment of End Stage Liver Disease Due to Hepatitis B Infection

Start date: n/a
Phase: Phase 2
Study type: Interventional

The purpose of this study is to compare the use of HepeX-B versus HBIg, two anti-viral drugs, in patients who have received liver transplants due to liver failure caused by Hepatitis B infection. Patients will be evaluated over a 6 month to 1.5 year period to evaluate whether or not the drugs prevent the Hepatitis B virus from infecting the new liver.

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?
