Active clinical trials for "Hepatitis B, Chronic"

Bile acids regulating farnesoid X receptor (FXR) interact with hepatitis B virus replication. EYP001a is a selective, synthetic FXR agonist under development for the treatment of hepatitis B. This Phase 1b study is designed primarily to determine the safety, tolerability, pharmacokinetics and pharmacodynamics of EYP001a in chronically HBV infected subjects.

A Safety and Tolerability Evaluation of Ascending Single Oral Doses of Metacavir Enteric-coated Capsules Using a Randomized，Double-blind, Placebo-controlled Design conducted in Chinese Healthy Adult Volunteers.

This is a Phase4, multicenter, open-label, randomized study to demonstrate that the Tenolid Tab switching group is non-inferior to the virologic suppression effect compared to the Viread Tab continuous administration group and evaluate the safety of Tenolid Tab. This clinical trial was conducted on patients who were taking Viread Tab as monotherapy for more than 48 weeks for chronic hepatitis B. At the time of screening(Visit 1), information on factors related to medical history and prognosis including Viread Tab administration were collected retrospectively from the subjects who voluntarily signed the informed consent form (ICF). Only subjects who are determined to be suitable for the study eligibility(inclusion/exclusion) criteria as a result of the screening evaluations are randomized in a 1:1 ratio to one of the two groups at the baseline. Subjects will receive investigational product start on the next day of randomization for 48 weeks. Subjects will visit to the study site on 12, 24, 36, 24 weeks after starting dosing investigational product and evaluated for effectiveness of virologic suppression and safety.

Liver disease associated with persistent hepatitis B virus (HBV) infection remains an important public health problem with significant morbidity and mortality. In spite of the existence of an effective vaccine, worldwide approximately 260 million people are chronic HBV surface antigen (HBsAg) carriers and current treatment with interferon and/or nucleoside analogues (NA) is not able to achieve a complete cure. The key obstacle to HBV eradication is the persistence of HBV DNA in the nuclei of infected hepatocytes, either integrated into the host genome or as a covalently closed circular DNA (cccDNA) episomal form. While HBV integration is rare and its clinical implications still require investigation, cccDNA plays an essential role in the long-term persistence of HBV infection and can often be detected even following NA therapy and HBsAg seroconversion. Since quantification of cccDNA in infected hepatocytes requires invasive liver biopsy, more accessible tissues, such as serum or peripheral blood mononuclear cells (PBMCs) have been investigated in different patient populations.

This is a randomized, double-blind, placebo-controlled study in viremic chronic hepatitis B subjects, assessing the safety, tolerability, pharmacokinetics and antiviral activity of 28 Days treatment with EDP-514.

This is a multi centre, two parallel arm, randomized, open-label, Phase 2a experimental study of oral Farnesoid X Receptor (FXR) modulator EYP001a to assess its safety and anti-viral effect when administered to non-treated (treatment naive or off treatment) chronic Hepatitis B (CHB) patients in combination with entecavir (ETV) and pegylated interferon alpha2a (peg-IFN). An experimental treatment period of 16 weeks will be followed by a 24 week maintenance period with ETV standard of care (SoC).

This is a phase IV, open label, historical controlled comparative study to evaluate the efficacy and safety of Ricovir® in maintaining durability of viral response in CHB patients who have been treated with Viread® and have undetectable HBV DNA in serum by real-time polymerase chain reaction (PCR) assay.

This phase Ib study included two parts in which Part I was to evaluate the safety and bridge for PK among healthy Chinese subjects and Part II were about study among Chinese chronic hepatitis B virus-infected patients. Study of Part II was carried out following the safety assessment and racial difference evaluation in Part I.

A single center, randomized controlled trial design was used to select patients with chronic hepatitis B in the immune control period (HBsAg positive, HBeAg negative, normal ALT, HBsAg ≤ 1500iu/ml, HBV DNA ≤ 2000iu/ml) to enter the study, and to compare the feasibility, effectiveness and safety of pegylate combined with Granulocyte-macrophage colony stimulating factor, high-dose hepatitis B vaccine and pegylate monotherapy in the treatment of patients with chronic hepatitis B in the immune control period

The purpose is to evaluate efficacy and safety of therapeutic HBV vaccine (mimogen-based) treatment in chronic hepatitis B patients and to explore the most effective dosage and provide the rational for optimal dosing schedule.
