Filter by:The immune mechanism of the nucleos(t)ide analogs (NAs) in inhibiting HBV replication effectively while having a low sustained virus control rate after drug withdrawal is unclear. B cell immunity and antibody response are the keys to prevent HBV reinfection and keep the virus under control. T-bet+ B, which can be regulated by IL-21, is a newly discovered major effector B cell in protection of pathogens and it is a main subtype of HBsAg-specific B cells. Thus, we suspect that T-bet+ B may play a role in ongoing controlling of the virus after withdraw of NAs in CHB patient. Based on our previous studies on CHB immunity, we use the RNAseq analyse, flow cytometry, and Elispot assay to analyze the frequency, function, and phenotype of B cells in CHB patients with different profiles after withdraw of NAs.
The primary objectives of this study are to evaluate the safety and tolerance of single and multiple oral administration of PA3670 tablets in Chinese adult healthy subjects and the effect of food on pharmacokinetics of PA3670 tablets in Chinese adult healthy subjects.
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.
The primary objectives of this study are to evaluate the safety, tolerability and pharmacokinetics characteristics of single ascending dose (SAD) of PA1010 tablets in Chinese healthy adults and the impact of food and gender on the pharmacokinetics
The primary objective of this study is to evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic characteristics of multiple ascending dose (MAD) of PA1010 tablets in Chinese adults with Chronic Hepatitis B.
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.
Part 1 is a randomized, double-blind, placebo-controlled study. It will assess the safety, tolerability, and pharmacokinetics of single and multiple orally administered doses of EDP-514 in healthy adult subjects. Part 2 is randomized, double -blind, placebo-controlled study including subjects with Hepatitis B Virus. It will assess the safety, tolerability, pharmacokinetics and antiviral activity of 28 Days of orally administered doses of EDP-514 in nucleos(t)ide reverse transcriptase inhibitor (NUC)-Suppressed Patients with Chronic Hepatitis B Virus Infection
As an alternative biomarker of intrahepatic covalently closed circular DNA(cccDNA) transcriptional activity, hepatitis B virus(HBV)RNA may evolve during long-lasting virus-host interactionsduring chronic hepatitis B viral infection.The distribution pattern of serum HBV RNA levels in the natural course of chronic HBV infection remains unclear. Furthermore,serum HBV RNA was associated with response to NAs. So it may be another clinical surrogate marker for intrahepatic cccDNA level after long-term NAs treatment and be used to monitor NAs therapy. The aim of this study was to evaluate thelevels of HBV RNA during the natural courseof CHB and the role in distinguishingthe natural phases of HBV infection and to investigate whether serum HBV RNA level at the end of long-term NAs treatment had a similar or better predict effect on off-therapy relapse than serum HBsAg titer.
Primary Objective: To evaluate the efficacy of 6-week Eltrombopag to treat immune thrombocytopenia with chronic hepatitis B virus infection. Secondary Objective: To evaluate the efficacy and safety of 6-week and 22-week Eltrombopag to treat immune thrombocytopenia with chronic hepatitis B virus infection.
The primary objectives of this study are to evaluate the safety and efficacy of GS-4774 in adults with chronic hepatitis B (CHB) viral infection who have been virally suppressed with an oral antiviral (OAV) medication.
