Active clinical trials for "Hepatitis B"

Although screening, brief intervention, and referral to treatment (SBIRT) approaches are effective in reducing alcohol misuse and its associated risk-taking behaviors and negative consequences, there is little research demonstrating the effectiveness of SBIRT for illicit and/or prescription drug misuse. Misusers of illicit and/or prescription drugs frequently seek medical care in emergency departments (EDs), particularly for reasons related to their misuse. As a result, the ED is well suited as a site to conduct an analysis of the effectiveness of SBIRT for this population. The Brief Intervention for Drug Misuse for the Emergency Department (BIDMED) study is a randomized, controlled, trial that will include adult ED patients at a large, academic, trauma center (Rhode Island Hospital) and a community hospital (The Miriam Hospital) who have a subcritical illness or injury and whose screening indicates illicit and/or prescription drug misuse. BIDMED participants will be randomized to receive screening only (SO) or brief intervention (BI) with appropriate referral to treatment. Participants will complete a battery of blinded baseline assessments using standardized instruments as well as adapted instruments specific to the aims of this study. All participants will undergo blinded follow-up assessments at three, six, and twelve months post-randomization. The primary hypotheses addressed in the BIDMED study are that, compared to participants in the SO arm, participants in the BI arm will show a significantly greater reduction in: (1) drug misuse within the prior 30 days at three months post-randomization, (2) behaviors associated with drug misuse at six months post-randomization; and (3) negative physical health, psychosocial health, and socioeconomic consequences at twelve months post-randomization. As a secondary aim, the impact of BI compared to SO will be assessed on participants contacting, enrolling in, and completing a drug treatment program. In addition, the impact of BI compared to SO on increasing uptake of HIV and hepatitis B/C screening will be measured. A mechanisms of change model that addresses the expected mediators and moderators of change to explain the effects of SBIRT in this setting will also be developed and tested. Further, the epidemiology of illicit and/or prescription drug misuse will be assessed in a random sample of ED patients.

An open study to evaluate the Efficacy, Safety of Clevudine monotherapy or Adefovir and Clevudine combination in Proportion to Roadmap Concept in patients with chronic hepatitis B Associated Hepatocellular Carcinoma

This is a randomized, open-labelled, prospective 96-week study comparing the antiviral efficacy and safety of switching to entecavir 1 mg QD from lamivudine versus maintaining lamivudine 100 mg QD treatment in HBV-infected subjects currently receiving lamivudine monotherapy.

This 3 arm study will assess the efficacy and safety of PEGASYS alone, or in combination with Adefovir or Entecavir in patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms sc weekly for 48 weeks + placebo from weeks -4 to 2;2)PEGASYS 180 micrograms sc weekly for 48 weeks + Adefovir from weeks -4 to 2; or 3)PEGASYS 180 micrograms sc weekly for 48 weeks + Entecavir from weeks -4 to 2. Treatment will be followed by 24 weeks of treatment-free follow-up.The anticipated time on study treatment is 1 year, and the target sample size is 100-500 individuals.

A primary hepatocellular carcinoma (HCC) is generally regarded as unresectable if the future liver remnant (FLR)≤40％ of total liver volume in patient with underlying liver disease, such as hepatitis B. In China, TACE is the most common treatment for these unresectable HCC. Recently, PVE has been employed to enlarge the FLR of the patients so as to increase the resectability and surgical safety of major hepatectomies. In order to shut the arterio-portal shunt in the liver and control the tumor progress TACE sometimes is performed before PVE. In this study we design a randomized control trial to investigate the efficacy of sequential TACE and PVE on increasing the resectability of hepatitis B related HCC compared with TACE alone.

This study is working to research the efficacy and significant of the anti-virus therapy in the unresectable Hepatitis B virus (HBV) related primary liver cancer(PLC) so as to establish treatment standards of anti-virus therapy in PLC.

The objectives of this study are to demonstrate that entecavir has antiviral activity with undetectable at Week 48, and to assess the safety and the pharmacokinetic in Japanese patients given entecavir at each dose of 0.1 and 0.5 mg for 52 weeks

A randomized, parallel, multicenter, active-controlled with 48 weeks of treatment period. Patients will be randomized to receive clevudine alone for 48 weeks or clevudine for 24 weeks followed by 24 weeks of clevudine in addition to monthly HBV vaccination.The purpose of this study is to investigate efficacy of combination of clevudine and HBV vaccine over clevudine alone in patients with chronic hepatitis B infection.

This study is to evaluate the antiviral efficacy of add-on adefovir to telbivudine in non-responders to telbivudine monotherapy after 24 and 36 initial weeks. Antiviral efficacy is assessed by hepatitis B virus (HBV) DNA non-detectability (PCR <300 copies/ml) by week 104 with CHB.

HBe seroconversion is an important goal for anti-HBV treatment, since it is associated with a non progressive liver infection and a better clinical outcome. However, the rate of HBe seroconversion is low in HIV-HBV co-infected patients, mostly treated by tenofovir and emtricitabine. This study will evaluate the efficacy and the safety of a one-year Peg-interferon alpha 2a additional treatment in patients already treated by tenofovir and emtricitabine without reaching HBe seroconversion.
