Filter by:This non-interventional clinical study will be conducted to prospectively collect serial plasma samples from subjects with chronic HBV infection who are initiating antiviral therapy. These samples will be used to estimate clinical utility endpoints for the Aptima HBV Quant assay, which is used as an aid in the management of HBV-infected patients undergoing HBV antiviral therapy.
The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of vesatolimod in participants with chronic hepatitis B (CHB) infection currently being treated with oral antivirals (OAV). Participants will be randomized in 3 sequential cohorts (Cohorts A, B, and C). Within each cohort, participants will be randomized in a 1:3:3:3 ratio to placebo or one of the doses of vesatolimod (1, 2, or 4 mg).
The purpose of this long-term follow-up study was to evaluate the persistence of the cellular and the humoral immune response 4 years after the first dose of GSK Biologicals' investigational vaccine formulations containing HBsAg (used as a model antigen) and an adjuvant.
The main objective of this study was to evaluate the safety and immunogenicity of 10µg/0.5ml and 5µg/0.5ml hepatitis B vaccine made by recombinant deoxyribonudeic acid techniques in saccharomyces cereviside yeast for infants and other age groups.
Liver cancer and hepatitis B are health disparities for Asian Americans, and hepatitis C is a rising problem. Little is known about how to improve the quality of health care Asian Americans receive for viral hepatitis. Technology, specifically mobile applications, can provide a flexible and efficient way to address these challenges. This project seeks to develop, implement, and test an intervention to increase hepatitis B and C screening for Asian Americans in 2 healthcare systems in San Francisco. The research team will develop, implement, and evaluate the efficacy of an interactive, patient- centered mobile app for use on a tablet computer to increase hepatitis B and C screening among unscreened Asian Americans age 18 and older. The team will use their experience in health promotion to develop the intervention by working with patients, community leaders and advocates, clinical staff, healthcare providers, and healthcare system administrators from a county safety net system and an academic primary care practice in the San Francisco Bay Area. The mobile application will include video clips with a physician (Video Doctor) addressing patient concerns regarding hepatitis B and C screening in the patient's preferred language, English, Chinese, or Vietnamese. A patient who has not been screened for hepatitis B will answer questions about his or her characteristics and preferences using the mobile application. The mobile application will then show 30-60 seconds video clips with messages that address the patient's responses related to hepatitis B screening and that are delivered by an actor playing a physician. Those who are born between 1945 and 1965 also receive messages about hepatitis C screening. At the end, the tablet computer will generate a provider alert to let the treating provider know what the patient's preferences are regarding testing for viral hepatitis. Once developed, the intervention will then be used in combination with a physician panel notification and tested against physician panel notification only in a randomized controlled trial to see which approach is better in increasing the rate of hepatitis B and C screening. The team will also work with the 2 healthcare system to ensure that the interventions will be practical and easily adopted once the study is over. The findings of this project will greatly expand understanding about how to use technology- based interventions to improve quality of healthcare in diverse patient populations.
The West African Treatment Cohort for Hepatitis B (WATCH) study is a component of the European Commission Funded FP7 project PROLIFICA. It aims to evaluate a number of steps required to successfully treat patients with chronic hepatitis B virus infection to prevent cirrhosis and liver cancer. The first step is to determine whether screening for hepatitis B using a point of care test is feasible and effective. The second is to monitor linkage from screening into care. The third is to evaluate cheap non-invasive assessments to determine the need for treatment. The fourth is to determine what proportion of patients meet treatment eligibility criteria. The fifth step is to establish a treatment cohort which can be used to measure adherence to therapy and avoidance of HBV related complications. A parallel untreated cohort will be established to determine whether treatment criteria are relevant in this West African setting by monitoring for complications of HBV infection.
An exploratory clinical trial to evaluate the pharmacokinetic characteristics of I.V. Hepabig injection used for prevention of hepatitis B relapse after liver transplantation.
The purpose of the study is to evaluate the safety and immunogenicity of an investigational hepatitis B vaccine (HEPLISAV) in adults 18 to 70 years of age.
This study will assess the seroprevalence of hepatitis A virus (HAV), hepatitis B virus (HBV) and Bordetella pertussis (B. pertussis) in adolescents and young adults in Mexico.
This Phase 1 trial will assess the dose-related safety and PK profile of different doses of NVR 3-778, first in healthy volunteer subjects (part I) and subsequently in patients with chronic hepatitis B (part II). Additionally, in Part II, changes in patients' serum HBV DNA levels and other virologic efficacy parameters will be assessed.
