Filter by:China's new cases and deaths of hepatocellular carcinoma (HCC) rank first in the world. hepatocellular carcinoma is the third most morbid, second-most mortal malignancy in China. Up to 80% of hepatocellular carcinoma patients caused by HBV infection. Antiviral therapy can significantly reduce the incidence and mortality of hepatocellular carcinoma in patients with chronic hepatitis B (CHB), hinder the progression of liver disease, and effectively control the disease. However, studies in recent years have found that long-term therapy with Nucleos(t)ide analogue (NAs) cannot completely eliminate the risk of liver cancer in patients with chronic hepatitis B. In addition, a number of retrospective studies at home and abroad have shown that compared with long-term oral NAs, peginterferon can significantly reduce the risk of hepatocellular carcinoma in patients with chronic hepatitis B. However, there is limit prospective studies. This multicenter, randomized, open-label, controlled trial study is aim to evaluate the pegylated interferon alfa-2b injection in comparing to NAs in reducing the incidence of hepatocellular carcinoma, to provide evidences for new management and treatment strategy options for improving clinical outcomes for the chronic hepatitis B patients. About 267 chronic hepatitis patients with intermediate to high risk of liver cancer who are now receiving nucleoside therapy will be enrolled. Subjects will be randomized into the peginterferon combined NAs group and the NAs monotherapy group at a ratio of 2:1. Level of HBsAg, proportion of patients with HBsAg clearance and seroconversion, incidence of liver cirrhosis and hepatocellular carcinoma will be assessed.
Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.
Chronic hepatitis B virus (HBV) infection remains a global public health burden around the world. Investigating the disease process of chronic hepatitis B (CHB) is essential to individual management in clinical practice. According to American Association for the Study of Liver Diseases (AASLD) 2018 Hepatitis B Guidance, CHB can be classified into four phases: immune-tolerant CHB, HBeAg-positive immune active CHB, inactive CHB and hepatitis B e antigen (HBeAg)-negative immune active CHB. Antiviral therapy is recommended in patients with HBeAg-positive or -negative immune active CHB patients to reduce the incidence of liver cirrhosis and hepatocellular carcinoma, while periodic monitoring is recommended for inactive carrier and immune-tolerant CHB patients. However, a substantial proportion of patients fall into an indeterminate phase whose serum HBV DNA and alanine aminotransferase levels do not fit well into these well-described phases. Most of CHB patients with indeterminate phase are HBeAg negative. However, the clinical outcomes of these patients remain unclear. Therefore, the purpose of this study is to investigate the clinical outcomes of HBeAg-negative chronic hepatitis B patients with indeterminate phase.
A Randomized, Double-blind, Placebo-controlled and Multicenter Phase Ⅱ Clinical Trials To Evaluate the Safety, Efficacy and Pharmacokinetics of GST-HG141 Tablets in Treated Chronic Hepatitis B (CHB) Patients With Low Viremia.
This study is intended to confirm the efficacy, safety, pharmacokinetic (PK) profile, and the durability of hepatitis B virus surface antigen (HBsAg) suppression observed with bepirovirsen for 24 weeks (with loading doses) as compared to the placebo arm. This study will have 4 stages: a) Double-blind treatment (bepirovirsen or placebo) for 24 weeks. b) Nucleos(t)ide analogue (NA) treatment for 24 weeks. c) NA cessation stage OR Continue NA for 24 weeks. d) Durability of response and follow up for further 24 weeks for participants who stopped NA treatment at Week 48. The arms will be stratified based on HBsAg level (HBsAg greater than or equal to [≥] 100 international unit per milliliter [IU/mL] to less than or equal [≤]1000 IU/mL or greater than [>] 1000 IU/mL to ≤3000 IU/mL) at screening. The total duration of the study, including screening (up to 60 days), the double-blind treatment stage (24 weeks), the On NA only stage (24 weeks), and the NA cessation and durability stages (48 weeks) is up to approximately 104 weeks at maximum for each participant.

Background: People who were born outside of the country are the largest group of adults infected with chronic hepatitis B virus (HBV) in the US. HBV affects the liver. If not treated, HBV infection can lead to serious liver disease, including cancer. One recent study showed that only 35% of foreign-born US adults were aware of their HBV infections. Foreign-born US adults may also have trouble getting proper care after they are diagnosed with HBV. In one small survey, language, cultural, and financial barriers were cited as the biggest reasons for not receiving care. To help more people with HBV, researchers want to learn how to find and overcome any barriers to care. Objective: This natural history study seeks to identify and better understand barriers that prevent foreign-born US adults from getting proper care for HBV infections. Eligibility: People aged 18 years and older with chronic HBV who were born outside of the US. Design: Participants will visit the NIH clinic 1 time. This visit will take about 20 minutes. Researchers will review participants medical records and collect information about their HBV. Participants will complete a survey. They will answer questions about: Where they came from. When they came to the US. How well they have adapted to living in the US. The health care they have received for HBV. Their age, gender, and education. Participants will be paid $10 for completing the survey. ...
This study will be conducted in three parts: Part A: A prospective open label pilot intervention study, comparing the proportion of people with hepatitis B who are managed by their GP in primary care settings before, 12 months and 24 months after implementation of the Simply B electronic hepatitis B support package. Part B: A nested qualitative health services feasibility study using semi -structured interviews and thematic analysis
This is a Phase 1b/2 platform study framework to evaluate the safety and efficacy of investigational candidate(s) and their combinations as potential treatments for adults with chronic hepatitis B virus infection.
Chronic hepatitis B (CHB) patients may be unsatisfied to entecavir (ETV) therapy due to the inconvenience in drug taking, i.e., fasting for more than 2 hours and/or dose adjustment according to estimated glomerular filtration rate (eGFR). However, tenofovir alafenamide (TAF) has been approved to be highly effective and safe in patients with CHB, and is convenient in drug taking, i.e., once daily regardless food taking and renal function.Therefore,TAF can be a good option in CHB patients who are unsatisfied to ETV therapy. The aim of this prospective cohort study is to assess the improvement on satisfaction (including drug adherence) of TAF switch therapy in CHB patients who are unsatisfied to ETV therapy. In addition, with expected adherence improvement in TAF switch therapy, the efficacy of TAF switch therapy may be improved, and the efficacy benefits can be evaluated by the changes of some novel biomarkers, such as HBV core-related antigen (HBcrAg). The investigators therefore aim to conduct a prospective cohort study of TAF switch therapy for CHB patients who are unsatisfied to ETV therapy.
