Active clinical trials for "Hepatitis B"

The goal of this clinical trial is to test ISA104 in patients with chronic hepatitis B. The main question[s] it aims to answer are: How safe is ISA104? Does ISA104 induce immunity against hepatitis B virus? Different doses of the vaccine ISA104 will be administered to participants. These participants are chronic HBV patients being actively treated with antiviral drugs. Researchers will compare the ISA104 vaccine to a placebo.

There will be 124 patients diagnosed as hepatitis B associated acute on chronic liver failure with mild to moderate hepatic encephalopathy will be enrolled in this study according to the inclusion and exclusion criteria, and will be randomly divided into two groups as 1:1.First group is called Rifaximin group, on the basis of comprehensive treatment of liver failure, Rifaximin (Alfa Sigma S.p.A) is added, three times a day, 400 mg each time, for a total of 4 weeks, and observed until 12 weeks after withdrawal. The other group is called standard treatment group (control group), which will receive routine comprehensive treatment for liver failure. The reversal of mild to moderate hepatic encephalopathy in the two groups of patients will be observed within 4 weeks, then follow up to 12 weeks.

The goal of this clinical study is to learn more about GS-2829 and GS-6779 in healthy participants and participants with CHB.

A Randomized Study of ALG-000184 Drug to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics After Single and Multiple Doses in Healthy Volunteers and CHB Subjects

The objective of this study is to evaluate the safety and efficacy of ASC22 in the treatment of chronic hepatitis B after single and multiple drug administration.

A randomized controlled trial to study the efficacy of addition of FMT & plasma exchange to tenofovir compared to monotherapy with tenofovir in patients with HBV reactivation who develops Acute on chronic liver failure. In this study the patients who meet the inclusion criteria will be randomized to either receive Tenofovir or with FMT + plasma exchange along with Tenofovir . Blood samples & stool samples will be taken & analysis will be done accordingly .The patients are followed for 90 days MELD,APACHE & SOFA scores are calculated.Then statistical analysis will be done to find whether the addition of plasma exchange & FMT adds benefit compared to tenofovir treatment alone .

This study is to investigate the clinical efficacy and safety of Nucleoside (acid) analogues treatment in patients with normal Alanine Aminotransferase and positive Hepatitis B virus DNA.

There are about 400 million chronic hepatitis B virus (HBV) infection patients worldwide, posing a serious threat to global public health security. In China, HBV infection occured mainly in the perinatal period or infants, and about 10% of patients in the immune tolerance stage spontaneously transit to the immune clearance stage every year and become HBeAg-negative chronic HBV infection, resulting in a significant increase in the number of inactive chronic hepatitis B (CHB) patients. In recent years, different guidelines have not reached consensus on the need to initiate antiviral therapy for inactive CHB patients: In the guidelines of Asian Pacific Association for The Study of Liver(APASL)-2015 and American Association for the Study of Liver Diseases(AASLD)-2018, antiviral therapy is generally not recommended for this group of patients, and regular outpatient follow-up is recommended. Guideline of European Association for the Study of the Liver(EASL)-2017 suggests that people with a family history of cirrhosis and liver cancer at this stage could be treated with antiviral therapy even if they did not meet the indications of antiviral therapy. According to Guidelines for the Prevention and Treatment of Chronic Hepatitis B (version 2019) of China, antiviral therapy is still recommended for some patients with inactive HBsAg carrier status who are HBV DNA positive and meet the treatment indications. Studies have shown that some patients in immune tolerance stage may enter the immune clearance stage and have hepatitis flare. Patients of inactive CHB have the potential to develop HBeAg-negative CHB, and studies of long-term follow-up in this population have indicated the risk of hepatocellular carcinoma. With the popularization of the concept of functional cure for chronic hepatitis B, more and more people with inactive CHB have a strong desire for treatment. In recent years, several studies have demonstrated that Pegylated-interferon therapy can achieve high functional cure rate in patients with inactive CHB. The purpose of this study is to establish a national multi-center, prospective real world study to compare the efficacy of different antiviral treatment regimens for patients with inactive CHB and seek for the factors of functional cure.

This study is to investigate the clinical efficacy and safety of three types of nucleotide/nucleoside analogues in treatment of chronic hepatitis b

The Study will evaluate the effects of VVX001, a novel vaccine for hepatitis B, to elicit a robust protective IgG immune response in vaccine naive subjects in subjects who failed to demonstrate seroconversion after treatment with a licensed hepatitis B vaccine and in patients chronically infected with HBV.
