Active clinical trials for "Hepatitis C"

To demonstrate that colocation treatment of substance use disorder and Hepatitis C infection concurrently while proving addiction counselling will achieve increased duration of sobriety and elimination of Hepatitis C virus in study participants.

This study will determine whether assisted partner notification services (APS) can identify and link to care, the sexual and needle-sharing partners of HIV-infected and HIV/hepatitis C (HCV) co-infected persons who inject drugs (PWID). It will also define the risk factors for onward HIV and HCV transmission among PWID using viral phylogenetics.

To assess the prevalence of blood-borne viral infections in prisons in Belgium, screening will be executed in several prisons in Flanders, Brussels and Wallonia to obtain a geographical representative distribution. Upon informed consent screening will be performed using whole capillary blood (finger prick testing) with three different tests for HCV Ab, HBsAg and HIV. Screening will be performed first. While awaiting the test result (15-20min), the participant can fill out a questionnaire (together with the study nurse), concerning risk factors for HCV, HBV and HIV infection. This questionnaire is filled out directly online, and will be immediately implemented in the encoded database. The database is set-up according to the rules of good clinical practice. (Castor EDC software). The results will be filled out immediately by the prison staff in this database after it is filled out by the participant, minimizing the risk of displacement of test results.

TEMPO is an interventional cohort study recruiting injecting drug users attending needle and syringe programs (NSP) in Australia. Three hundred participants will be invited to on-site HCV testing with NSP integrated care for HCV treatment. Participants will be screened for HCV using point-of-care testing and HCV positive participants will be offered treatment with Sofosbuvir/Velpatasvir. Of those who initiate treatment, participants will receive weekly peer-based support on-treatment and return at End of Treatment (ETR) and 12 weeks following end of treatment (SVR12) for clinical follow-up.

HepQuant tests are new liver tests that are being developed to accurately measure liver function with sensitivity and specificity while being safe and non-invasive. The primary goal of this study is to define the intra-individual reproducibility of the HepQuant tests, that is, to see if a person is given the tests several times that the test results are essentially the same each time. Subjects for this study will include healthy controls and patients with chronic liver diseases. The chronic liver diseases will include hepatitis C virus (HCV) infection and a serious form of fatty liver disease, known as non-alcoholic steatohepatitis (NASH). The HCV and NASH patients will include men and women, and those with early stage and late stage liver disease as defined by the amount of fibrosis observed in their liver biopsies. Once a subject has been enrolled in the study they will be given the HepQuant tests on three separate days within the span of one month. The hypothesis of this study is that HepQuant tests will reproducibly report liver function in healthy controls and patients with all stages of chronic HCV and NASH liver disease and that liver function will decrease as the amount of liver fibrosis increases in the chronic liver disease patients.

This study will evaluate the technical feasibility of using fine needle aspiration (FNA) of liver tissue to obtain vaniprevir (MK-7009) liver pharmacokinetic (PK) data, working towards identifying a minimally invasive, reproducible platform to measure liver PK. The study will be done in 2 parts. In Part 1, participants will be randomized to one of five FNA/core needle biopsy (CNB) time-point collection sequences. In Part 2, participants will be randomized to one of two possible doses of vaniprevir and will be assigned to one of five FNA/CNB time-point collection sequences; participants in Part 2 will also receive background therapy with pegylated interferon alpha-2b (Peg-IFN alpha-2b) and ribavirin (RBV). The primary hypothesis is that there is a greater than 80% posterior probability that vaniprevir concentrations are successfully obtained at least 60% of the time from FNA liver samples collected at 2 of 3 specified timepoints.

This is a pilot, monocentric, prospective, randomized control trial looking at the use of rapid tests as a part of normal care. The investigators will be testing for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). Testing will be proposed to all persons seeking care at the Centre d'Accueil, de Soins et d'Orientation from the organization Médecin du Monde (CASO, MDM). Infection status of participants will be determined by either the standard test (ELISA) or rapid test. The choice between tests will be determined randomly. The overall goal is to determine the general acceptability and feasibility of rapid tests and to see if they can help individuals increase their awareness of infection status when compared to longer, routine methods of testing. In addition, results from these tests will allow the medical doctor to guide participants to appropriate care. All positive tests will be confirmed at a specialized hospital (Hôptial Saint-Antoine, Paris, France) and health-specific information will be obtained four months after testing.

This study aims to compare the role of peginterferon α-2b (50 μg/week) vs. control (no treatment) in the prevention of hepatocellular carcinoma, in adult patients with cirrhosis and initial signs of portal hypertension who did not respond to previous combined therapy with interferon alfa + ribavirin or peginterferon alfa + ribavirin or to interferon alfa monotherapy and with a high proliferation rate before entering the study. The duration of treatment will be 3 years, and the follow-up period will be 2 years.

The rapidly progression of the disease in HIV-HCV co-infected patients justify the treatment. Combination of Peg interferon and Ribavirin is the best treatment because it improve the compliance of treatment. In APRICOT study genotypes 2 and 3 patients received 48 weeks and the rates of end of treatment response was 64% and the sustained virological response (24 weeks after the end of treatment) 62%. In mono-infected patients trials showed there are not differences in the sustained virological response between 24 and 48 weeks of treatment, however exit the doubt concerning the different kinetic viral in HIV-HCV co-infected patients and this could be related with a lost of profit with a shorter duration of treatment, only 24 weeks. In this study we woud like to evaluate if 24 weeks of treatment in HIV-HCV co-infected patients genotype 2 or 3 will have the same rate of clearance of virus at the end of follow-up period.

Iron excess is increasingly regarded as an important cofactor in the morbidity attributed to many disorders. Assessment of body iron stores by measurement of serum ferritin concentrations has poor specificity and the most reliable method is histological or biochemical assessment from a liver biopsy. Because liver biopsy is an invasive procedure, imaging methods have been developed to detect and quantify hepatic iron content. The aim of the study is to use a simplified magnetic resonance imaging (MRI) technique to quantify simultaneously iron and fat contents in the liver and to compare the results to the quantification obtained biochemically.
