Active clinical trials for "Hepatitis B"

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.

HYPOTHESIS: The investigators hypothesize that sonoelastography (SE) will provide accurate quantitative measurements that can be used to stage liver fibrosis in patients with chronic liver disease. To measure liver stiffness with sonoelastography in adults with suspect diffuse liver disease who will undergo non-focal liver biopsy as part of their routine clinical care To assess the sensitivity and specificity of sonoelastography for the detection and staging of liver fibrosis To evaluate the effect of steatosis and inflammation on the estimation of liver fibrosis using sonoelastography

The purpose of this study is to evaluate the efficacy and safety of telbivudine and lamivudine use during late pregnancy for the prevention of HBV perinatal transmission in highly viraemic mothers.

The purpose of this study is to Evaluate the efficacy and safety of Hepabulin IV (HBIG, a study drug) after liver transplantation.

This study evaluates the immunogenicity and safety of Infanrix hexa™ (DTPa-HBV-IPV/Hib) when administered as a primary vaccination course to Indian infants according to a 6-10-14 weeks or a 2-4-6 months schedule.

To explore the antiviral effect of nucleoside analogue in late pregnancy and the safety of the antiviral drug to fetus.To establish the best therapy strategy to pregnant women with high level of HBV DNA.

The aim of this clinical trial is to evaluate the efficacy, safety, and tolerability of Niuliva (Hepatitis B virus immune globulin) in the prophylaxis of hepatitis B virus (HBV) reinfection in patients submitted to liver transplantation due to HBV-induced liver disease by reaching and maintaining certain hepatitis B antibody (HBsAg) levels considered as protective during the first six and twelve months post-transplantation.

This is a study to evaluate immunogenicity, safety, and tolerability of 2XP HEPTAVAX™-II compared with the 1XP HEPTAVAX™-II in healthy Japanese young adults.

Immunoprophylaxis failure of hepatitis B virus (HBV) leading to vertical transmission remains a concern and has been reported in approximately 8-15% of infants born to hepatitis B e antigen (HBeAg) positive mothers with high levels of HBV DNA. Maternal HBV DNA > 6log10 copies/mL (or >200,000 IU/mL) is the major risk for the mother-to-child transmission. Prior observational studies have shown that antiviral therapy including lamivudine or telbivudine use during late pregnancy can safely reduce the rate of vertical transmission in this special population compared to untreated patients. Tenofovir Disoproxil (TDF), a pregnancy category B medication, reduces HBV DNA and normalizes serum alanine aminotransferase (ALT) in chronic hepatitis B patients (CHB) with few adverse effects. Two aspects on tenofovir use in pregnancy will be evaluated prospectively in this study: The data on its tolerability and safety in HBeAg+ pregnant women with HBV DNA > 6log10 copies/mL (or > 200,000 IU/mL) during late pregnancy and infants. Its efficacy in the reduction of HBV vertical transmission rate.

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.
