Active clinical trials for "Hepatitis B, Chronic"

The TARGET-HBV study engages an observational research design to conduct a comprehensive review of outcomes for patients with CHB infection. The initial phase of the study that enrolled patients treated with tenofovir alafenamide (TAF) was successfully completed. The current protocol (Amendment 1) describes the second phase of the study that will engage research activities for patients being managed for CHB in usual clinical practice in the US and Canada. The study addresses important clinical questions regarding the management of CHB by collecting and analyzing data from patients at academic and community medical centers. TARGET-HBV creates a robust database of real-world data regarding the natural history, management, and health outcomes related to antiviral treatments used in clinical practice.

The REACH-B study establishes an observational cohort study of people living with chronic hepatitis B from a national network, including a diverse range of services, to characterise and monitor hepatitis B linkage to care and treatment requirements amongst this population.

The purpose of this study is to determine the disease progression in CHB/NAFLD compared with CHB and NAFLD including liver cirrhosis, cirrhotic complications and hepatocellular carcinoma (HCC).

Hepatitis B virus (HBV) infection is still a major public health problem worldwide. There are 260 million people with chronic HBV infection in the world, and 890,000 people die of HBV-related diseases annually. Mother-to-child transmission (MTCT) is still the main transmission route of HBV in high-endemic areas, such as China, sub-Saharan Africa, etc. Fortunately, the morbidity of HBV infection is gradually decreased in China, because newborns are administrated with the combined immunization of hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) widely. However, some infants born of mothers with high HBV DNA load (≥2×10^5 IU/ml) are still infected with HBV even if these infants receive the combined immunization on time. Therefore, guidelines including American Association for the Study of Liver Diseases (AASLD) and European Association for the Study of Liver Diseases (EASL) recommend that pregnant women with high HBV DNA load should take anti-hepatitis B viral drugs (tenofovir disoproxil fumarate or terbivudine) to reduce MTCT of HBV from gestation 24-28 weeks. Although tenofovir disoproxil fumarate (TDF) has been classified as B drug for pregnancy by Food and Drug Administration (FDA), some side effects of TDF are reported. For example, neutropenia and the decrease of bone mineral density are found in early age infants who are ever exposed to TDF during their fetal life. Tenofovir alafenamide (TAF), a new prodrug of tenofovir (TFV), has a higher antiviral potency, a higher peripheral blood mononuclear cell (PBMC) intracellular tenofovir diphosphate (TFVpp) level and a lower plasma TFV concentration. As the successor of TDF, the dose of TAF that is took orally every day is approximately 1/10 of TDF. TAF has a much lower risk of kidney toxicity and has almost no effect on the bone mineral density. TAF has been approved and recommended as the first-line drug to treat patients with chronic hepatitis B (CHB) by AASLD, EASL, etc. However, there are relatively few data of TAF on pregnancies with high HBV DNA load. It is urgently to clarify the safety and efficacy of TAF on interrupting MTCT of HBV in pregnancies with high HBV DNA load. In the present study, the investigators enroll middle/late pregnancies with high HBV DNA load(≥2×10^5 IU/ml). The participants are randomly divided into two groups. Then the participants are treated with TAF or TDF respectively. All enrolled participants are followed-up for 2 years. Objectives of the present study are as follows: A. To clarify safety and efficacy of TAF on interrupting MTCT of HBV in middle/late pregnancies with high HBV DNA load. B. To clarify effects of TAF on obstetric complications in middle/late pregnancies with CHB. C. To clarify effects of TAF on birth defects of infants born in mothers with CHB. D. To clarify the change of virology and biochemistry indexes in women with CHB during pregnancy and postpartum. E. To clarify effects of TAF treatment on participants. F. To clarify growth parameters of the infants exposed to TAF during their fetal life. G. To clarify the pharmacokinetics of TAF in pregnant populations.

The aim of study is to evaluate the current prevalence of HDV infection, and comprehensively analyze the interaction between HDV and HBV infections in the era of NAs in Taiwan. Investigators plan to set up a platform for HDV positive patients in Taiwan to invite sites or hepatologists who are interested in this field.

This is a phase 1 study in which healthy adult subjects will receive TQA3038 or placebo and will be assessed for safety, tolerability, pharmacokinetics. In the single ascending dose (SAD) part, healthy adult subjects will receive one dose of TQA3038 or placebo, administered subcutaneously (SC).

CB06-036 is an investigational drug developed by Shanghai Zhimeng Biopharma Inc. for the treatment of Chronic Hepatitis B.

This three-part, Phase 1 protocol will be the first clinical study of AB-101. Parts 1 and 2 will be a Phase 1a SAD/MAD of AB-101 in healthy adult subjects. Part 3 will be a Phase 1b dose-ranging assessment of AB-101 in non-cirrhotic Chronic Hepatitis B (CHB) subjects.

This multicenter retrospective study aims to study the association between the presence of MAFLD and change in liver stiffness over time in untreated and treated patients with chronic hepatitis B

This study is a Phase IIIb extension trial following the "randomized, double-blind, placebo-controlled, entecavir basic treatment, multi-center Phase III clinical trial of hydroxnidone capsules in the treatment of liver fibrosis of chronic viral hepatitis B". The main objective of this study is to evaluate the effectiveness and the safety of hydroxyeidone capsules for long-term treatment of patients with chronic viral hepatitis B liver fibrosis.
