Active clinical trials for "Hepatitis"

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.

The purpose of this study is to see if treatment of chronic hepatitis C in people who are on opiate replacement therapy such as methadone or buprenorphine (including patient who still inject drugs) is safe and effective.

The general aim of this study is to determine if 3 MIU of IFN-α5 in monotherapy, and 1,5 MIU of IFN-α5 combined with 1,5 MIU of IFN- α2b, are safe dose levels as well as to investigate the antiviral efficacy and pharmacodynamics (PD) of such doses and drugs in treatment-experienced HCV patients with genotype 1 chronic infection, after 29 days of treatment. It is also intended to determine pharmacokinetics (PK) of the safe dose achieved of IFN-α5 in monotherapy.

Participants with genotype 1 HCV infection were randomized to 1 of 3 sofosbuvir doses (100 mg, 200 mg, or 400 mg) or matching placebo once daily based upon stratification for IL28B status (CC or CT/TT). Placebo tablets were administered to participants receiving 100 mg active sofosbuvir (3 placebo tablets) and 200 mg active sofosbuvir (2 placebo tablets) in order to maintain the study blind. Participants received sofosbuvir/matching placebo from Day 0 to 27. Participants also received treatment with PEG+RBV starting on Day 0 of the study which continued for 48 weeks. Participants were evaluated for sustained virologic response (SVR) for an additional 24 weeks following completion of study treatment.

The purpose of the study is to investigate the effect of moderate and severe hepatic impairment on the pharmacokinetics of TMC435. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. In addition, the short-term safety and tolerability of TMC435 in participants with hepatic impairment will be determined. The results of this study will guide dose recommendations for TMC435 in patients with impaired liver function.

The main objective is to evaluate the hepatic safety of raltegravir when compared to efavirenz, both in combination with tenofovir and emtricitabine as first-line HIV treatment in patients with HIV and hepatitis C coinfection.

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 study will evaluate the efficacy and safety of MP-424 with Peginterferon Alfa-2b and Ribavirin (RBV) in patients with genotype 2 hepatitis C, who did not respond to previous treatment.

Up to 120 patients with chronic hepatitis C will be enrolled in a study of viral kinetics and liver gene expression before and during combination therapy with peginterferon and ribavirin. Adult patients with chronic hepatitis C virus (HCV) infection who have compensated liver disease and have not received interferon in the past will be randomized into one of four groups. Groups A and C will undergo liver biopsy before starting peginterferon therapy and Groups B and D will undergo biopsy 6 hours after the initial dose of peginterferon. Furthermore, Groups C and D will receive a run-in period of 4 weeks of ribavirin therapy before starting peginterferon. All patients will receive the standard recommended doses of peginterferon alfa 2a (180 mcg sc weekly) and ribavirin (1000 or 1200 mg daily for genotypes 1, 4-6 and 800 mg daily for genotype 2 and 3) for up to 48 weeks (24 weeks for genotype 2 and 3). All patients in Groups C and D, irrespective of genotype, will be pretreated with ribavirin at a dose of 1000 or 1200 mg, depending on patient body-weight. After the initial peginterferon injection, patients will have blood taken and symptoms recorded at 6, 24, 48, 72 hours and weekly thereafter for four weeks to assess viral kinetic response. Liver biopsy tissue taken before or 6 hours after the initial dose of peginterferon will be assessed by standard light microscopy and also subjected to RNA extraction and microarray analysis of mRNA expression. Patients will be monitored carefully during therapy and tested regularly for HCV RNA levels. Therapy will be given for 48 weeks, but will be discontinued early for patients with genotype 1 infection if HCV RNA levels do not decline by at least 2 log IU/ml by week 12 (lack of an early virological response) or do not decline to undetectable levels by week 24 (lack of HCV RNA clearance). Patients with other genotypes with be treated for a full course of therapy regardless of early responses. After completing therapy, patients will be followed at 4 to 8 week intervals and undergo repeat medical evaluation with liver biopsy 24 weeks after stopping therapy. The primary clinical criterion for success of therapy is a sustained virological response, as marked by the absence of HCV RNA from serum at least 24 weeks after stopping. The focus of this study, however, will be on viral kinetics comparing patients who were pretreated with ribavirin (Groups C and D) to those who were not (Groups A and B) as well as on gene expression studies assessing the effects of peginterferon on intrahepatic mRNA profiles by comparing Group A and B and the effects of ribavirin by comparing Group A to Group C and Group B to Group D. Results will also be compared between different HCV genotypes. These studies are aimed at assessing the mechanisms of action of peginterferon and ribavirin against HCV and evaluating the basis for the lack of virologic response to combination therapy.

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.
