NCT04168333
Hepatitis B virus (HBV) infection is a worldwide health problem. It has been proved that the persistence of HBV is associated with the failure to stimulate an efficient HBV-specific immune response. T101, the Chinese counterpart of TG1050, is a replication-defective adenovirus serotype 5 (Ad5) expressing multiple HBV-specific antigens (core, polymerase and envelope) and is used as therapeutic vaccine for chronic hepatitis B patients. The application of T101 aims at inducing a broad HBV-specific cellular immune response and ultimately eliminating HBV infection.
NCT06906016
Chronic Hepatitis B Virus (HBV) infection affects nearly 300 million people worldwide and is a leading cause of liver fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). In France, it affects around 0.3% of the population. Current clinical practice relies on traditional biomarkers, such as HBV DNA and HBsAg, to monitor viral replication and disease progression. However, these biomarkers do not fully capture the viral activity or predict clinical outcomes. Recently, new biomarkers like HBcrAg and HBV RNA have emerged, showing promise for better understanding the natural history of the infection and guiding treatment decisions. The main objective of this research is to evaluate the predictive role of these biomarkers (HBcrAg, HBV RNA) in HBV-infected patients, focusing on their association with HBsAg seroconversion and their ability to predict clinical events like cirrhosis and HCC. Secondary objectives include describing the clinicobiological characteristics of patients, determining HBV genotypes, characterizing the impact of HBV on the host's transcriptome, and studying the biomarkers' role in different phases of the infection and treatment. The ultimate goal is to identify more accurate biomarkers to guide antiviral treatment, predict disease progression, and potentially determine when treatment can be safely discontinued.
NCT06159062
The goal of this intervention research is to learn about the safety and tolerability of 162 with a single ascending dose in subjects with chronic hepatitis B virus (HBV) infection.
NCT04199715
This is a preliminary trial of a Hepatitis B vaccine (Heplisav-B) in medically immunosuppressed patients. The purpose of this study is to test the ability of Heplisav-B to produce high levels of antibody that neutralize the virus and prevent hepatitis B from coming back. Another important purpose is to test the safety of this vaccine in patients taking immune suppressive medicines.
NCT07519330
Study HH006-202 is designed to assesses the efficacy and safety of HH-006 in adults chronic HBV infection. Eligible participants will receive study treatment for 48 weeks. All treated patients will also undergo a follow-up period after last study drug treatment.
NCT07183306
This study is A multicenter, open-label, partial multiple-ascending doses phase1b/2 in which participants with chronic hepatitis B virus (HBV) infection will receive HT-101 and/or HT-102 and be assessed for safety, tolerability, Pharmacokinetics, and Pharmacodynamics. Approximately 86 patients with chronic hepatitis B infection were planned to be recruited. Among them, Group A and Group AA received HT-101 injection, administered once every 4 weeks (Q4W), at least for 24 weeks. Group B received HT-102 injection, administered Q4W for 24 weeks and sequential dosed with HT-101 for another 24 weeks. Groups C, D, and E received HT-101 injection combined with HT-102 injection, administered once every 4 weeks for 24weeks. During the study period, all subjects received nucleoside (acid) analogues (NAs) treatment.
NCT05057065
HBV(hepatitis B virus) with metabolic comorbidities may accelerate liver disease progression and increase the risk of HCC(Hepatocellular Carcinoma)development. It is reported combination of metabolic diseases and CHB is associated with substantially increased rates of liver cirrhosis and secondary liver-related events compared to CHB alone. Consequently, hepatitis B patients with metabolic comorbidities warrant particular attention in disease surveillance and evaluation of treatment indications.
NCT03854630
The primary aim of this open-label, randomized control trial is to compare the immunogenicity at week 28 after 20µg HBV vaccine (at week 0, 4, 24) versus 40µg HBV vaccine (40-µg at week 0, 4, 24 week) among HIV-positive patients or HIV-negative MSM who were born in Taiwan after July 1986 and tested negative for all HBV serological markers. The secondary aims are to assess the safety of double-dose HBV vaccination, the proportions of high-level responders (anti-HBs antibody \>100 mIU/ml) at weeks 28 and 48, the serological responses at week 48, and incident HBV infection (indicated by appearance of anti-HBc and/or HBsAg) at week 48.
NCT02128503
This study aims to determine the prevalence of HBV infection in patients with IBD and rheumatologic disease, and to assess the impact of immunosuppressive therapy on viral load and clinical course of IBD patients.
NCT05542979
This is a multicenter, randomized, double-blind, placebo-controlled, multiple-ascending dose phase Ib study of HH-003 injection, which is a monoclonal antibody targeting Hepatitis B virus. This study aims to evaluate the safety, tolerability and pharmacokinetics of HH-003 injection in treatment-naive participants chronically infected with hepatitis B virus.
NCT04423393
This is a Phase 1 study in which healthy volunteers and participants with chronic HBV infection will receive VIR-3434 or placebo and will be assessed for safety, tolerability, pharmacokinetics (PK), and antiviral activity (only in participants with chronic HBV infection).
NCT07511218
The goal of this clinical trial is to evaluate the safety, tolerability, immunogenicity and Pharmacokinetics (PK) characteristics of AHB-171 Injection in healthy participants (Part A) and participants with chronic hepatitis B (CHB, Part B), and assess its preliminary efficacy in CHB participants.
NCT00106964
Hepatitis B is a contagious virus that can damage a person's liver. It can be prevented by vaccination, but for many HIV-positive people, the vaccines do not help them achieve adequate protection against this virus. In an attempt to improve response to vaccination and achieve protection from hepatitis B, this trial will compare the immune system response to 3 hepatitis B vaccine regimens in HIV-positive adolescents 12 through 24 years of age.
NCT04289987
The purpose of this study is to evaluate the efficacy and safety of the investigational medicinal product CVI-HBV-002.
NCT06513286
This study is an open-label, ascending dose phase 1b/2a trial to assess the safety and immunogenicity of a heterologous protein prime/MVA boost therapeutic hepatitis B vaccine in patients with chronic HBV who are virally suppressed with oral anti-viral therapies.
NCT05392387
Hepatitis B virus (HBV) infection is a major global health issue with 257 million chronically infected individuals. Of note, China has the largest population accounting for one third of the world's infected population. Approximately, about 300 000 people die each year due to the consequences of HBV. In 2016, the World Health Organization (WHO) proposed the goal for elimination of hepatitis B as public health threat by 2030 and China will be a major contributor towards this global goal. Currently, two approved therapeutic strategies are available including pegylated interferon (IFN) or nucleos (t) ide analogues (NA), which could suppress HBV replication and slow disease progression. Here, investigators hope to launch a cohort study to reveal the clinical features relating to therapeutic efficacy of antiviral therapy and the prognosis of patients with differential therapeutic strategies.
NCT05612581
