Filter by:In recent years, vitamin D (VD) has received much attention in the fields of host immune regulation, inflammation, fibrosis, cell proliferation and differentiation and tumor. VD works by binding to the vitamin D receptor (VDR). VDR is mainly distributed in giant cells, dendritic cells, T cells and lymphocytes. Four SNPs of VDRS have been most studied: TaqI (rs731236), FokI (rs10735810), ApaI (rs7975232), and BsmI (rs1544410). At present, more and more patients have been treated with oral nucleotide/nucleoside analogues (NAs) with direct antiviral drugs in China, and a large part of them show low expression of HBsAg. Clinical cure can be pursued for these patients, that is, HBsAg turns negative. A number of studies have been carried out at home and abroad. In this study, We will recruit CHB patients with low HBsAg levels. They all will receive pegylated interferon treatment and were randomly assigned to a vitamin D treatment or a control group. A final assessment will be made to determine whether vitamin D levels would affect the clearance rate of HBsAg.
This study is an open-label, ascending dose phase 1a trial to assess the safety and immunogenicity of a heterologous protein prime/MVA boost therapeutic hepatitis B vaccine
The goal of this clinical trial is to test the outcomes of HBsAg(+) patients in the treatments of NAs vs NAs plus IFN . The main questions it aims to answer are: 1. Clinical effect analysis of nucleoside analogs (NAs) group a group and NAs plus interferon group after 48 weeks of treatment; 2. Repetitive effect and time effect of different drug treatment at different follow-up time points; 3. To evaluate the difference of therapeutic effect of NAs or NAs combined with interferon; 4. Follow up and compare the incidence of early liver cancer in each group. Participants will be asked to receive NAs or NAs combined with interferon treatments, and Regular blood sampling and color ultrasound examination. Researchers will compare control group to see if occurrence of liver cancer.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of AHB-137 subcutaneous injection in healthy volunteers and in chronic hepatitis B (CHB) patients after single and multiple doses. In addition, the study will evaluate the initial antiviral efficacy of AHB-137 in CHB patients following a multiple dosing regimen.
Chronic hepatitis B (CHB) affects an estimated 292 million people, and causes approximately 800,000 people deaths per year from liver-related complications including cirrhosis and hepatocellular carcinoma, remaining a major global public health issue.Meanwhile, the rising incidence of metabolic syndrome (MetS) is another grim health burden. Combined MetS affects the metabolic function of hepatocytes, which are responsible for providing HBV replication. Antiviral therapy is an effective measure to reduce the risk of cirrhosis and liver cancer in patients with chronic CHB. Combined MetS may affect the antiviral efficacy in patients with CHB.This prospective observational study examines the differences in HBeAg serological conversion rates between HBeAg-positive CHB patients with and without MS who received first-line oral antivirals for 144 weeks.
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.
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.
