This phase III trial studies the effect of hepatitis B antiviral (anti-HBV) therapy in preventing liver complications in patients with chronic or past hepatitis B virus (HBV) who are receiving anti-cancer therapy for solid tumors. People with chronic or past HBV who are undergoing therapy for cancer are at an increased risk for changes in the liver which could be minor or severe. Anti-HBV therapy acts against infections caused by HBV and may help reduce the chance that HBV gets worse or comes back in patients receiving anti-cancer therapy for solid tumors.
The purpose of this study is to determine if ABI-H0731 given in combination with a standard of care (SOC) entecavir (ETV) is safe and effective in participants with chronic hepatitis B infection (cHBV)
The main purpose of this study is to evaluate efficacy of 24 weeks of study treatment, in terms of changes in hepatitis B surface antigen (HBsAg) levels.
The goals of therapy against chronic hepatitis B are to decrease the morbidity and mortality related to chronic HBV infection. Currently available antiviral therapy can suppress viral replication but only a small proportion attain functional cure, which is defined as HBV surface antigen-to-antibody seroconversion. Hepatitis B surface antigen (HBsAg) is a marker of persistent hepatitis B infection. It has been observed that patients who had both hepatitis B and hepatitis C, and who were treated for their hepatitis C with 12 weeks of ledipasvir/sofosbuvir for had a decline in HBsAg levels. This study hypothesizes that a similar decrease would be seen in mono-infected hepatitis B subjects over the course of 12 weeks treatment with ledipasvir/sofosbuvir.
The goals of this clinical study are to compare the effectiveness, safety and tolerability of study drug, tenofovir alafenamide (TAF), versus placebo in teens and children with CHB and to learn more about the dosing levels in children.
Participants with chronic HBV infection will receive multiple doses of ARC-520 in combination with entecavir or tenofovir and be evaluated for safety and efficacy.
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).
Dose cohorts may be dosed with one of up to 4 possible total weekly doses (0.3 mg, 1 mg, 2 mg, 4 mg). Dose escalation or repetition will be governed by pre-specified safety and activity rules. Subjects will be confined on days 1-3 and/or days 8-10. Follow-up visits are required periodically through day 43. Subjects with sustained reductions in HbsAg will be requested to return for additional follow-up follow-up visits at 3 and 6 months post last dose. Study procedures involve blood draws for pharmacokinetic, pharmacodynamic, virologic, and safety assessments
The purpose of this study is to find the best monthly dose schedule for the new Hepatitis Immune Globulin (Boca HBVIg, a study drug) when used in combination with an antiviral agent Lamivudine after liver transplantation. Boca HBVIg will be given along with Lamivudine to prevent hepatitis B reinfection following liver transplantation in patients with end stage liver failure due to hepatitis B infection.
The purpose of this study is to determine the safety and efficacy of treatment using a combination of drugs (entecavir and pegylated interferon) in children ages 3-\<18 years old with immunotolerant chronic hepatitis B.
Hepatitis B Virus Antibody Booster Program
Background: * The hepatitis B vaccine has been shown to be safe and effective in preventing transmission of the hepatitis B virus. Response rates to the initial three doses of the vaccine are high, with significant or even complete immune response. However, this level has been reported to decline rapidly within the first year and more slowly thereafter. There is little data on the durability and long-term protection provided by the hepatitis B vaccine administered to adults in the United States. * Vaccinated individuals are believed to be protected against hepatitis B virus infection because of a memory immune response. Even if antibody levels are low, the immune system will still be able to produce enough antibody to neutralize the hepatitis B virus. Therefore, booster doses of the vaccine are not recommended, except for some high-risk individuals such as patients on dialysis. Researchers are interested in determining the durability of the immune response of the hepatitis B vaccine in adults with low or intermediate risk for hepatitis B virus infection. Objectives: - To examine the long-term immune status of human immunodeficiency virus (HIV) positive and negative individuals who received the hepatitis B vaccine during adulthood, compared with the immune status of individuals who acquired natural immunity by recovering from acute hepatitis B during adulthood. Eligibility: * Individuals at least 18 years of age who were vaccinated against hepatitis B at least 10 years ago. * Individuals at least 18 years of age who contracted and recovered from acute hepatitis B at least 10 years ago. * Individuals at least 18 years of age who have well-controlled HIV and were vaccinated against hepatitis B at least 10 years ago. Design: * Participants will have a single outpatient study visit and potential follow-up visits as part of this protocol. * Participants will complete a questionnaire assessing possible risk factors for hepatitis B infection, and will provide blood samples to test for hepatitis B antibodies and other immune system studies. * Participants will receive a letter or phone call with the results of the blood tests: * Those who no longer have protective levels of antibody against the hepatitis B virus will be offered a booster dose of the hepatitis B vaccine. To monitor immune response to the booster vaccine, additional study visits will be scheduled at 1 and 3 weeks following the booster. * Those who have chronic infection with the hepatitis B virus will be advised to follow up with their primary care physician, and may be eligible to participate in ongoing treatment trials for chronic hepatitis B. * Those who have abnormal blood tests will be referred back to their primary care physician for investigation of the abnormal tests results, and may also be referred to other National Institutes of Health protocols. * Additional tests will evaluate immune response to the measles, mumps, and rubella (German measles) viruses. Some participants may be advised to have an additional MMR vaccine through their primary care physician.
The purpose of this study was to evaluate the safety and efficacy of entecavir in pediatric patients with chronic hepatitis B virus infection
The purpose of the study is to evaluate the safety, immunogenicity and lot-to-lot consistency of an investigational hepatitis B virus vaccine, HEPLISAV™, in healthy adults 40 to 70 years of age
In this study, researchers from UCLA and Friends Community Center will work together in designing a program to assist young homeless stimulant-using gay and bisexual homeless men to complete the hepatitis vaccine and in reducing drug and sexual activity. Using nurse case management strategies, found successful with homeless adults as well as contingency management strategies, found successful with gay and bisexual homeless adults by the community partners, the investigators will evaluate the effectiveness of a program that combines both strategies. As stimulant use threatens to increase homeless persons' risk of exposure to hepatitis A and B viruses, particularly among young users who may not yet be HBV-infected, this research is targeted to engage this group in treatment, until they are suitably protected from HBV, and hopefully reduce risk for HCV and HIV as well.
Adult liver cancer is the third leading cause of cancer deaths worldwide. The major risk factor for liver cancer is hepatitis B virus (HBV) infection. The purpose of the study is to sequence the HBV genome in patients with chronic HBV infection, and in patients with liver cancer resulting from chronic HBV infection. The goal is to identify mutations in the HBV genome that predisposes these high risk individuals to the development of liver cancer.
We propose a largely retrospective study with short-term prospective follow-up in a subgroup of patients who have not yet been treated with 48 weeks of entecavir following partial response to adefovir. The aim of the study is to describe sequential virologic response to adefovir and entecavir.
The purpose of this study is to further evaluate the safety and seroprotective immune response of a new investigational hepatitis B virus (HBV) vaccine, HEPLISAV™, in subjects 11-55 years old. The primary hypothesis is that HEPLISAV™ is well tolerated.
