Active clinical trials for "Hepatitis"

The research project aims to understand how pharmacies can be involved in the identification and treatment of hepatitis C (hep C). The study will look at the effectiveness of hep C testing and treatment through pharmacies with support from the Cool Aid Community Health Centre (CACHC). The study will also evaluate the readiness of pharmacies to take on these extra tasks at the pharmacy. This information will be used to develop future strategies to better detect, treat and prevent hep C.

This is a pilot study to determine the safety and efficacy of a novel adjuvanted hepatitis B virus (HBV) vaccine formulated as a potential therapeutic vaccine against chronic HBV infection. An ongoing human clinical trial of this HBV vaccine in a prophylactic setting has confirmed this vaccine to be more effective at inducing seroconversion as measured by development of Hepatitis B surface antibody (HBsAb) in poor responder subjects than the standard alum-adjuvanted HBV vaccine, providing promise that this new vaccine may also be able to induce HBV viral control and/or seroconversion in chronically infected subjects

This is an observational, longitudinal, prospective study for sample collection and evaluation for future therapy or disease progression of chronic hepatitis B and C. Participants will be seen on an annual basis with optional additional visits for up to 10 years and provide samples for research and evaluation of disease progression. In addition, there is a longitudinal sub-study for treatment of hepatitis B that will involve 2 years of treatment with tenofovir alafenamide and blood collections with optional liver biopsies.

Primary biliary cholangitis (PBC) is an autoimmune chronic liver disease, characterised by destruction of the small intrahepatic bile ducts. Ursodeoxycholic acid (UDCA) is the first line treatment for patients with PBC. However, up to 40% of patients respond inadequate to this treatment. sCD163 is a macrophage activation marker shedded into plasma by macrophages in the liver. sMR is a soluble mannose receptor. The investigators want to investigate whether sCD163 and sMR can predict response to treatment with UDCA in newly diagnosed patients with PBC.

To determine the treatment efficacy, safety and long-term outcomes of chronic hepatitis C patients receiving directly acting antivirals in Taiwan

Through bio-sampling this study investigates the relationship between the frequency and function of the cells of a patients immune system and how these change and impact on the outcome of alcoholic hepatitis. the investigators will examine the role of different cells of the immune system and how they may determine the outcome of this condition. The investigators will also look at how established treatment strategies impact on the frequency and function of these cell subsets.

The TARGET-HBV study engages an observational research design to conduct a comprehensive review of outcomes for patients with CHB infection. The initial phase of the study that enrolled patients treated with tenofovir alafenamide (TAF) was successfully completed. The current protocol (Amendment 1) describes the second phase of the study that will engage research activities for patients being managed for CHB in usual clinical practice in the US and Canada. The study addresses important clinical questions regarding the management of CHB by collecting and analyzing data from patients at academic and community medical centers. TARGET-HBV creates a robust database of real-world data regarding the natural history, management, and health outcomes related to antiviral treatments used in clinical practice.

This study will assess the safety and effectiveness of Maviret (Glecaprevir plus Pibrentasvir (GLE/PIB)) in adolescent participants diagnosed with chronic hepatitis C (CHC) in a real world setting across clinical practice in Japan.

Chronic hepatitis C remains a public health issue because up to 70 million people are chronically infected by hepatitis C virus (HCV) worldwide. Presence of advanced fibrosis/cirrhosis might be associated with liver-related complications, such as hepatocellular carcinoma and oesophageal varices bleeding. Oesophageal varices (OV) might be present in up to 40% of patients with liver cirrhosis have and the mortality rates from bleeding might be up to 20% per episode. Early diagnosis of advanced fibrosis/cirrhosis associated with hepatitis C treatment are key features for preventive and therapeutic measures to reduce liver-related mortality in HCV-infected patients. Liver elastography is a high accurate non-invasive test for diagnosis of advanced fibrosis/cirrhosis. Few different methods of liver elastography are currently available: transient elastography by Fibroscan and ultrasound elastography by point-shear wave (p-SWE) and 2D-shear wave (2D-SWE). Gastrointestinal endoscopy (GIE) has been considered the gold standard for screening or surveillance of esophageal varices. More recently, international guidelines have been recommending the use of non-invasive methods to indicate or avoid OV screening: Baveno VI guidelines proposed that compensated cirrhotic patients with a liver stiffness measurement (LSM) by transient elastography <20kPa and a platelet count >150,000/μL can avoid screening endoscopy. The use of direct-acting agents (DAAs) has revolutionized the treatment of chronic hepatitis C with high effectiveness shown using all-oral interferon-free regimens. HCV cure, sustained virological response (SVR), has been associated with lower rates of liver-related complications, increase in quality of life and decrease in waiting-list registrations for liver transplantation in patients with chronic hepatitis C. Preliminary studies have been reporting significant regression liver stiffness after SVR. However, it is unclear whether SVR might decrease portal hypertension leading to OV regression and a reduced risk of variceal bleeding. In addition, the use of non-invasive methods to avoid OV screening must be validated in HCV patients after SVR. The aims of this cross-sectional study with prospective inclusion of patients will be: (i) to evaluate the impact of SVR in portal hypertension in HCV patients with advanced fibrosis/liver cirrhosis treated by interferon-free regimens and (ii) to validate non-invasive methods to avoid OV screening by GIE

The investigators propose to compare the effectiveness of nontargeted rapid opt-out hepatitis C (HCV) screening versus targeted rapid opt-out HCV screening using recommended risk characteristics in multiple urban emergency departments (EDs) across the United States (Aim 1 - "Screening Trial").
