Active clinical trials for "Hepatitis A"

Subjects will be recruited and divided into 3 groups: Hepatitis A（Live）Vaccine，Freeze-dried produced by Changchun Institute of Biological Products Co., Ltd Hepatitis A（Live）Vaccine，Freeze-dried produced by Zhejiang Pukang Biotechnology Co., Ltd., and Hepatitis A（Live）Vaccine，Freeze-dried produced by Institute of Medical Biology, Chinese Academy of Medical Sciences. After immunization, the immunogenicity and safety of three different manufacturers will be compared and the data will be analyzed.

Hepatitis C Virus (HCV) infection is among the most common of all chronic liver diseases. HCV predominantly affects liver cells and causes the liver to become inflamed and damaged. This can lead to cirrhosis (scarring of the liver) and liver cancer leaving trial participants with need for liver transplant. The purpose of this study is to see how effective Glecaprevir/Pibrentasvir (GLE/PIB) is in a real world setting of participants with chronic HCV genotypes 1 to 6 and liver cirrhosis who have never received any treatment for HCV. GLE/PIB is a drug developed for the treatment of HCV infection. This is a prospective (future), observational study in treatment-naive (those who have not received treatment) participants with HCV genotypes 1 to 6 and compensated cirrhosis. All study participants will receive GLE/PIB as prescribed by their study doctor in accordance with approved local label. Pediatric (12 years and older) and adult participants with a diagnosis of HCV genotypes 1 to 6 and compensated cirrhosis will be enrolled in the study in Russian Federation. Participants will receive GLE/PIB tablets to be taken by mouth daily according to their physicians' prescription. The total duration of the study is 20 weeks, with a treatment period of 8 weeks and a follow up period of 12 weeks. There is expected to be no additional burden for participants in this trial. All study visits will occur during routine clinical practice and participants will be followed for 12 weeks.

The prevalence of hepatitis C virus infection (HCV) in patients with inflammatory bowel disease (IBD) ranges from 1-6%. Direct-acting antivirals (DAAs), with cure rates >90%, represent a radical change from interferon-based therapies. The ECCO (European Crohn's and Colitis Organisation) guidelines (Kucharzik T, Ellul P, Greuter T, et al. ECCO Guidelines on the Prevention, Diagnosis, and Management of Infections in Inflammatory Bowel Disease. J Crohn's Colitis. 2021;15(6):879-913) warns about the risk of IBD reactivation due to the effect of DAAs, but HCV management in this situation is uncertain given the lack of evidence. The project is proposed as the largest retrospective multicenter descriptive study carried out to evaluate the use of DAAs for HCV eradication in patients with IBD. The Eneida database (Zabana Y, Panés J, Nos P, et al. The ENEIDA registry (Nationwide study on genetic and environmental determinants of inflammatory bowel disease) by GETECCU: Design, monitoring, and functions. Gastroenterol y Hepatol. 2020;43(9):551-8.) of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) is an adequate registry to identify patients with HCV infection. The serological status of the infection is frequently recorded in the ENEIDA database, and it is generally evaluated at the time of IBD diagnosis, before starting immunosuppressive treatment. The ENEIDA registry has the advantage over large population studies that researchers have access to relevant details of the clinical history, which can respond to the controversies raised. This multicenter retrospective descriptive study will provide useful information to be able to give evidence-based recommendations regarding treatment of HCV in patients with IBD.

Post-marketing surveillance study to evaluate the real world safety and effectiveness of Viekira/ Exviera (paritaprevir/ritonavir/ombitasvir and dasabuvir) administered under a normal, routine treatment practice by Korean patients with Hepatitis C.

The goal of this study is to assess the health literacy level of patients enrolled in the HOPE program, identify any gaps in their knowledge of hepatitis C, analyze the variables that may influence patients' knowledge, and educate patients on Hepatitis C.

Investigators aim to study the effect of direct acting antiviral agents (DAAs) on behavior of hepatocellular carcinoma (HCC) and overall survival in patients with chronic hepatitis C (CHC).

This is an open-label, single arm cohort study to see efficacy and safety of tenofovir disoproxil fumarate (TDF) in naïve chronic hepatitis B, retrospectively and prospectively both.

This use-results post-marketing surveillance (PMS) study for Sovaldi® tablets (sofosbuvir, SOF) administered in combination with Rebetol® capsules (ribavirin, REB) will evaluate the safety and efficacy of SOF administered in combination with ribavirin under real world use in Japan. Among adult patients with chronic genotype 2 hepatitis C virus (HCV) infection and treated with SOF+ribavirin in routine clinical use, the primary objective of this study is to evaluate the incidence of adverse drug reactions (ADRs) under real world settings.

The interferon-free combination regimen of ombitasvir/paritaprevir/ritonavir/ with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well-controlled conditions. This observational study was the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Belgium in a clinical practice patient population.

The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions. This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Germany in a clinical practice patient population.
