Filter by:This study looks at protection in 10-11 and 15-16 year olds, immunized as infants with Hepatitis B (HB) vaccine to see if they still have residual protection against Hepatitis B disease. Adolescents will be invited to have a blood test and those without a minimal level of protection (antibody titer) will be offered a "test" vaccination to see if they still have capacity to recall an immune response. About one month later they will get another blood test to see if a booster response occurred. A few participants will have lost protection (no booster response) and will be offered a second HB vaccination to restore protection. Results of this study could influence the way in which children in British Columbia (BC) are immunized against HB disease.
Randomized trial of Hepatitis C-genotype 1-infected patients with compensated cirrhosis comparing the standard of care (Peginterferon/Ribavirin/Sofosbuvir) versus the off-label combination of simeprevir+ sofosbuvir without Ribavirin.
The purpose of this study was to evaluate the effect of treatment with ABT-450 co-formulated with ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333; 3-DAA regimen, with or without ribavirin (RBV) in adults with chronic hepatitis C virus genotype 1 (HCV GT1) infection.
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 study is to determine whether metadoxine is effective for improve survival and reduced oxidative stress in patients with severe alcoholic hepatitis.
The objective of this study is to identify a safe dose of MK-2248 in participants with Hepatitis C Virus (HCV) that mediates at least a 3 log10 reduction in viral load (VL) from baseline. It is anticipated that once-daily administration of a safe and well tolerated dose of MK-2248 will reduce VL by at least 3 log10 IU/mL.
The purpose of the study is to examine whether patients who have acute or early chronic hepatitis C virus (HCV) infection can be treated effectively and safely with an interferon-sparing regimen that combines a new direct acting antiviral drug (sofosbuvir) with one of the standard treatments for chronic hepatitis C (ribavirin). In particular, this study will investigate whether treatment of acute or early chronic HCV can be shortened. The study will assess efficacy by looking at the proportion of people who clear the virus (have no virus detectable in their blood) at the end of treatment, and 1, 3 and 6 months after treatment. The hypothesis is that short course (6 weeks) dual therapy using sofosbuvir and RBV will result in successful virological eradication in the majority (≥80%) of subjects treated for recently acquired HCV.
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.
