Active clinical trials for "Hepatitis"

Background: The global response to the HCV infection epidemic has been transformed by the availability of low-cost curative short course direct acting antiviral (DAA) therapy. Egypt has one of the highest burdens of HCV infection worldwide, and a large treatment programme, but reaching rural communities represents a major challenge. We report the feasibility and effectiveness of a comprehensive community-based HCV prevention, testing and treatment model in 73 villages across Egypt, with the goal to eliminate infection from all adult villagers. Methods: An HCV "educate, test and treat" programme was implemented in 73 villages across 7 governorates in Egypt between 06/2015 and 06/2018. The programme model comprised community mobilization facilitated by a network of village promoters to support the education, test and treat campaign as well as fund raising in the local community; a comprehensive testing, linkage to care and treatment of all eligible villagers aged 12 to 80 years using HCV antibody and HBsAg rapid diagnostic tests (RDTs), HCV RNA confirmation of positive cases, staging of liver disease using transient elastography (FibroScan), treatment with 12 or 24 weeks of a direct acting antiviral (DAA) regimen according to national standard of HCV care, and an assessment of cure at 12 weeks after completion of treatment (SVR12); and an education campaign to raise awareness and disseminate messages about safer practices to reduce transmission through public events, promotional materials and house-to-house visits. Key outcomes assessed in each village were: uptake of serological HCV and HBV testing, linkage to assessment and HCV viral load confirmation, uptake of treatment, and SVR12.

Unmethylated cystine-guanosine dinucleotide (CpG) motifs are pathogen-associated molecular patterns (PAMPs) associated with bacterial and viral-derived DNA that activate the innate and humoral immunity via toll-like receptor 9. This is a randomized controlled pilot study evaluating the clinical and immune correlates of a seroprotective immune response against a CpG-adjuvanted vaccine for hepatitis B.

The purpose of this study is to evaluate the safety and immunogenicity of the recombinant hepatitis B vaccine (Hansenula polymorpha, 10μg), with an open-labelled design in adults and randomized, double-blinded, and positive controlled design in children and neonates.

The purpose of the study is to determine if combination therapy with daclatasvir (DCV) and sofosbuvir (SOF) for 8 weeks is safe and effective in patients who have never been treated previously without liver cirrhosis who are chronically infected with hepatitis C virus (HCV)/HIV-1 Coinfection genotype (GT) 1, 2, 3, 4 patients.

This is a open label, randomized phase VI study, to assess the safety and immunogenicity of co-administration of Hepatitis E vaccine with Hepatitis B vaccine. The concomitant group (n =300) received Hepatitis B vaccine concomitantly with Hepatitis E vaccine at day 1 and months 1 and 6; The nonconcomitant group (n =150) received Hepatitis E vaccine at at day 1 and months 1 and 6. Another nonconcomitant group (n=150) received Hepatitis B vaccine at at day 1 and months 1 and 6. Anti-HEV IgG and HBsAb were determined. Injection-site and systemic adverse events (AEs) were monitored for 30 days after any vaccination; serious AEs were monitored throughout the study.

Objectives: Primary Objective: To identify and preselect patients with chronic HBV mono infection, who are undetectable for anti-Ad5 nAb, currently being treated with nucleo(t)sides, for participation in the TG1050.02 Phase1/1b First in Man (FIM) study. Secondary Objectives: To assess the prevalence of undetectable anti-Ad5 nAb in chronic HBV mono-infected patients. Methodology: Patients with chronic HBV mono-infection, who are currently being treated with nucleo(t)sides for their HBV infection, will be enrolled in this study to measure Ad5 nAb levels. A single peripheral blood collection (4 mL) will be obtained and Ad5 nAb titers will be measured by a central laboratory using a newly validated assay.

The purpose of this study is to compare the immunogenicity and safety of three different immunization schedules of inactivated hepatitis A vaccine (HAV) and/ or combined hepatitis A and B vaccine (HABV) in healthy Chinese infants.

Counseling intervention: Primary objective: to evaluate and compare, in at-risk populations, the efficacy of three different counseling methods in terms of propensity to come back for a HIV re-test. Secondary objectives: to evaluate and compare the efficacy of the counseling methods in terms of reported risk behavior and HIV knowledge as well as their acceptability and cost-effectiveness; describe the distribution of duration from HIV primary infection to detection; and estimate the prevalence of chronic hepatitis B and C, and syphilis in HIV-uninfected participants of targeted populations. Reminder intervention Primary objective: to evaluate and compare, in at-risk individuals who require frequent testing, the efficacy of reminders in terms of propensity to come back for a HIV re-test within 7 months. Secondary objective: to assess the cost-effectiveness of reminders. The interim analyses have shown that that some strategies are better than the others and the Advisory Committee recommended to use only the most efficient strategies (Computer assisted counseling and Scheduling an appointment and sending reminder to clients). In addition, CD4 cell count normal ranges in 30 HIV uninfected individuals in Thailand will be assessed. Transient elastometry (FibroScan) will be used to assess liver fibrosis in participants with and without viral hepatitis.

The purpose of this study is to assess the long-term persistence of immunity to hepatitis B in adolescents aged 14-15 years who were vaccinated with four doses of Infanrix™-Hexa in the first two years of life and to assess the anamnestic response, immunogenicity, safety and reactogenicity of a single challenge dose of the hepatitis B vaccine Engerix™-B Kinder.

The purpose of this study is to test the safety and efficacy of Civacir® to prevent the recurrence of Hepatitis C Virus (HCV) after liver transplant.
