NCT ID: NCT00606099 Withdrawn - Chronic Hepatitis B Clinical Trials

Efficacy and Safety of Telbivudine in Patients With Chronic Hepatitis B

Start date: November 2007
Phase: Phase 4
Study type: Interventional

This study is designed to evaluate the efficacy and safety of telbivudine 600mg versus adefovir dipivoxil 10mg in patients with compensated chronic hepatitis B.

NCT ID: NCT00606086 Completed - Clinical trials for Genotype 1 Chronic Hepatitis C

Safety and Efficacy of the Therapeutic Vaccine GI-5005 Combined With Pegylated Interferon Plus Ribavirin Standard of Care Therapy Versus Standard of Care Alone in Patients With Genotype 1 Chronic Hepatitis C Infection

Start date: December 2007
Phase: Phase 2
Study type: Interventional

The GI-5005 therapeutic vaccine in combination with standard of care or standard of care alone will be injected under the skin of HCV subjects. Patients will be monitored for safety, immune responses and any therapeutic benefits related to the injections including EVR, ETR, and SVR.

NCT ID: NCT00605384 Terminated - Chronic Hepatitis B Clinical Trials

A Phase IIIb Study to Compare Entecavir Plus Tenofovir vs. Adefovir Added to Continuing Lamivudine Therapy in Adult Patients With Lamivudine-Resistant Hepatitis B Infection

Start date: August 2008
Phase: Phase 3
Study type: Interventional

The purpose of this clinical research study is to find out whether a combination of entecavir (ETV) plus tenofovir (TNF) works better against Hepatitis B virus than adefovir (ADV) added to continuing lamivudine (LVD) therapy in patients whose Hepatitis B virus (HBV) is resistant against lamivudine. The safety of this treatment will also be studied.

NCT ID: NCT00603252 Completed - Hepatitis B Clinical Trials

Study to Show That the Combined Hepatitis A and B Vaccine is Non-inferior to Monovalent Vaccines in Adults

Start date: January 2008
Phase: Phase 4
Study type: Interventional

This protocol posting describes the booster phase of the study. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00289731).

NCT ID: NCT00602784 Completed - Chronic Hepatitis C Clinical Trials

Phase II Study of Immunization With a Hepatitis C Virus (HCV) Antigen Peptide Vaccine

Start date: November 2002
Phase: Phase 2
Study type: Interventional

The objectives are 1. to determine the immunological profile (CD4+, CD8+ cells, DTH) induced by immunization with HCV antigen peptide vaccine with polyarginine. 2. to document virological (HCV-RNA) and biochemical (ALT) responses following immunization with HCV antigen peptide vaccine with polyarginine. 3. to assess the safety of immunization with HCV antigen peptide vaccine with polyarginine.

NCT ID: NCT00598416 Completed - Hepatitis C Clinical Trials

Psychoeducation for Hepatitis and Alcohol Behaviors

Start date: September 2006
Phase: N/A
Study type: Interventional

The proposed project will apply a unique, effective family-responsive psychoeducation program, PsychoEducation Responsive to Families (PERF), for Hepatitis C Virus (HCV) treatment. The goal is to demonstrate that the intervention will enlarge the eligibility of some patients for HCV treatment and help sustain others through it.

NCT ID: NCT00597259 Recruiting - Chronic Hepatitis B Clinical Trials

Pegasys Plus Entecavir Versus Entecavir Alone for Hepatitis Be Antigen-Positive Chronic Hepatitis B

Start date: January 2008
Phase: Phase 4
Study type: Interventional

Although the best treatment choice for chronic hepatitis B is not clarified yet, certain therapeutic concepts could be derived from the experience of treating patients with chronic hepatitis C or human immunodeficiency virus (HIV) infection. A major advancement in treating hepatitis C or HIV infection has been the development of combination therapy. Whether the combination therapy using Peg-IFN alfa-2a plus ETV can achieve a long-term beneficial effect against ETV alone is not clarified. A prior single-arm pilot study suggested that similar combination therapy may be beneficial in patients with chronic hepatitis B. In this proposal, we thus hypothesize that the efficacy by using combination therapy with pegylated IFN alfa-2a plus ETV is superior to that by using ETV alone in that Peg-IFN may restore host immunity against HBV and prolonged ETV can maximize viral suppression. The objective of this clinical trial is to evaluate the efficacy of the combination of Peg-IFN alfa-2a at a dose of 180 mcg administered subcutaneously per week and ETV 0.5 mg daily for 24 weeks followed by ETV 0.5 mg daily monotherapy for an additional 120 weeks versus ETV 0.5 mg daily monotherapy for 144 weeks in patients with HBeAg-positive chronic hepatitis B. It will be an open-label, randomized, comparative, multi-center clinical trial. The recruited patients will be equally randomized into two treatment groups. Treatment-free follow-up period will be 48 weeks in both groups of patients. All subjects will be assessed for loss of HBeAg, presence of anti-HBe, loss of HBsAg, presence of anti-HBs, suppression of HBV DNA, and normalization of serum ALT at the end of treatment and end of follow-up. Genotypic and virologic resistance to ETV will also be assessed at baseline and at end of years 1, 2 and 3. The primary efficacy will be HBeAg seroconversion.

NCT ID: NCT00596960 Completed - Chronic Hepatitis C Clinical Trials

Study of the Effects of Motivational Enhancement Therapy on Alcohol Use in Chronic Hepatitis C Patients

Start date: November 2008
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether motivational enhancement therapy (MET) reduces alcohol use in a population of HCV-infected veterans who are currently drinking alcohol and have alcohol disorders. We hypothesize that veterans with HCV, an alcohol use disorder and continued excessive alcohol use who receive MET will have a greater reduction in the number of standard alcohol drinks per week and a greater percentage of days abstinent than veterans who receive health education control intervention.

NCT ID: NCT00596843 Completed - HIV Clinical Trials

Chronic Hepatitis Intervention Project for Drug Users

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

The purpose of this study is to determine if a 6-session motivational interviewing intervention is more effective than a 6-session educational intervention at reducing behaviors that may lead to infection, transmission, and progression of HIV and hepatitis C among out of treatment injecting drug users.

NCT ID: NCT00593151 Completed - Hepatitis C Clinical Trials

Study of Safety, Tolerability, and Anti-Viral Effect of Locteron Compared to PEG-Intron in Patients With Chronic Hepatitis C

PLUS
Start date: January 2008
Phase: Phase 1/Phase 2
Study type: Interventional

The purposes of the PLUS study were to confirm the safety and tolerability of two doses of LocteronTM (320 ug and 640 ug) dosed over four weeks in patients who had failed prior anti-HCV therapies (Panels A and B), and then to continue to study the safety, tolerability, and preliminary efficacy of the same two doses of LocteronTM (320 ug and 640 ug) in treatment-naïve genotype 1 HCV patients when Locteron dosed over 12 weeks (Panel C). All subjects were also to receive oral daily weight-based ribavirin.
