Active clinical trials for "Hepatitis B, Chronic"

Percutaneous liver biopsy (PLB) is the gold standard for grading necroinflammation and staging fibrosis in patients with chronic viral hepatitis. Whether the use of 1-deamino-8-D-arginine vasopressin (DDAVP) before PLBs in hemodialysis (HD) patients with chronic viral hepatitis has comparable safety profiles to those with normal renal function (NRF) has not been evaluated in prospective studies.

The study is a randomized, Double-Blind, Placebo-Controlled study to evaluate the safety, tolerability and pharmacokinetics, pharmacodynamics and food effect of HRS9950. The study will be conducted in three parts sequentially: Part 1, evaluate the safety, tolerability and pharmacokinetics, pharmacodynamics of single and multiple doses of HRS9950 tablet in healthy subjects. Part 1 will consist of 64 healthy subjects, 6 groups. Part 2, evaluate food effect of HRS9950 in healthy subjects. Part 2 will consist of 14 healthy subjects, 1 group (one of groups in Part 1). Part 3, evaluate the safety, tolerability and pharmacokinetics, pharmacodynamics of multiple doses of HRS9950 tablet in naïve and treatment-experienced chronic hepatitis B (CHB) patients. Part 3 will consist of 40 CHB patients, 1 group for naïve patients and 3 groups for treatment-experienced patients.

Clinical relapse occurred much earlier and tended to be more severe after cessation of TDF than ETV. The follow-up interval and intensity would be different between ETV and TDF after discontinuation of therapy. Whether switch therapy from TDF to ETV can modify the pattern of relapse is interesting but unclear. Our hypothesis is that entecavir consolidation on post-TDF treatment patients reduce and delay the clinical relapse effectively. Hence in this proof of concept study we would like to evaluate the effect of 6 months and 12 months of entecavir consolidation on post-TDF treatment durability.

The study is a randomized, Double-Blind, Placebo-Controlled study to evaluate the safety, tolerability and pharmacokinetics, pharmacodynamics and food effect of HRS5091. The study will be conducted in three parts sequentially: Part 1a will consist of 58 healthy subjects, 5 groups. The purpose of this part is to explore the safety, tolerability and pharmacokinetics of single doses of HRS5091 tablet in healthy subjects. Part 1b will consist of 18 healthy subjects and it is one of groups in Part 1a.The purpose of this part is to explore food effect of HRS5091 in healthy subjects. Part 1c will consist of 10 healthy subjects, 1 groups. The purpose of this part is to explore the safety, tolerability and pharmacokinetics of multiple doses of HRS5091 tablet in healthy subjects. Part 2 will consist of 30 CHB patients.The purpose of this part is to explore the safety, tolerability and pharmacokinetics, pharmacodynamics of multiple doses of HRS5091 tablet in naïve and treatment-discontinued chronic hepatitis B (CHB) patients.

The effectiveness of mother-to-child block of CHB in pregnant women in the middle and later stages of pregnancy has been recognized by the guidelines. TAF, as a newly marketed antiviral drug, has not been conclusively concluded in terms of its efficacy and postpartum safety in preventing mother-to-child transmission in pregnant women.Our purpose is to explore the TAF for CHB the curative effect of pregnant and postnatal security.

This study aims to demonstrate that patients with chronic hepatitis C (CHC) and B (CHB) experiencing regression of liver cirrhosis after effective antiviral therapy have decreased risk for hepatocellular carcinoma (HCC). Primary aim is to determine the incidence of HCC in patients with cirrhosis secondary to CHC and CHB, after treatment is provided, and to identify the magnitude of the decreased risk for HCC in patients experiencing regression of fibrosis. As a secondary aim, environmental risk factors for HCC development will be sought, in order to determine a subset of patients in whom it will be safe to stop surveillance.

This study aims to evaluate the prevalence and severity of hepatic steatosis in CHB and investigate the relationship between hepatic steatosis and viral load, liver biochemistry, liver fibrosis, and inflammation in CHB

The aim of this study was to evaluate knowledge and behavior of physicians regarding Hepatitis B Virus. The investigators designed a 30-item self-administered questionnaire assessing physicians' knowledge and behavior regarding chronic Hepatitis B Virus infection. These results provide data support for updating guidelines, continuing training, and even developing policies in medical insurance.

The purpose of this study is to recruit a random and representative sample of individuals within several Zambian communities for markers of Hepatitis B Virus (HBV) and to characterize chronic HBV infection and indications for treatment.

This retrospective study will evaluate the association of biomarkers and the treatment response of patients with chronic hepatitis B, who have completed therapy with Pegasys (peginterferon alfa-2a) ± lamivudine. For the analysis stored serum samples obtained from patients will be used; no actual patients are involved.
