Filter by:This is a phase 2 study in which subjects with chronic hepatitis B virus (HBV) infection will receive VIR-2218 alone or in combination with pegylated interferon alfa-2a and will be assessed for safety, tolerability, pharmacokinetics, and antiviral activity.
Entecavir 1 mg is commonly used in patients with chronic hepatitis B (CHB) patients with previous antiviral resistance. This study evaluates the efficacy and safety of switching to generic entecavir 1 mg (Baracle®, Dong-A Science Technology) in CHB patients taking brand name entecavir 1 mg (Baraclude®, Bristol-Myers Squibb) alone or in combination with other nucleos(t)ide analogues after the development of antiviral resistance. The primary aim is virological response (<20 IU/mL) at 12 months
In the current era of highly effective direct acting antiviral (DAA) therapy, the remaining obstacles to elimination of chronic HCV infection are identification of the high-risk groups, linkage to continued care and prevention of re-infection. It is estimated that 70-80% of patients with chronic HCV are unaware of their infection. Besides, public health education is limited and most patients are not aware that the current standard-of-care is highly effective, well tolerated and no longer require weekly subcutaneous injections. From a survey in Hong Kong in 2014, among 234 newly diagnosed HCV patients, only 20% agreed to undergo treatment. There is no universal screening programme for chronic hepatitis C infection in Hong Kong. and known high-risk patients include people who inject drugs (PWID), persons with certain medical conditions including those on hemodialysis, HIV infected, those with prior transfusion or organ transplantation. In this study, the investigators plan to reach out to PWIDs, people with substance abuse or prison inmates to provide rapid point-of-care screening for chronic hepatitis C infection, and to provide linkage to care for those diagnosed with chronic hepatitis C.
The primary objective of this study is to evaluate the efficacy of bulevirtide for treatment of chronic hepatitis delta (CHD) in comparison to delayed treatment.
The purpose of this study is to evaluate the efficacy and safety of GC1102 in combination of Nucleo(t)ide analogues (NAs) in patients with chronic hepatitis B
HBeAg-negative chronic hepatitis B (CHB) patients with low Level HBsAg were enrolled. After giving informed consent, patients were treated with nucleoside analog(s) (NAs) once a day and weekly subcutaneous injections of peginterferon alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week for 12 weeks. At week 12, the decrease of HBsAg was evaluated. ①If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/ mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. ②If the decrease of HBsAg is less than 50% compared to baseline level. The combination therapy of NAs and peginterferon alfa was extended to week 24. Then, the decrease of HBsAg was evaluated again. If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. If the decrease of HBsAg is less than 50% compared to baseline level. Peginterferon alfa was stopped, patients were treated with NAs once a day and then followed up for 48 weeks. Patients who maintained the original NAs treatment served as a control group.
A total of 2000 chronic hepatitis B (CHB) patients with liver biopsy performed at least 1 year after antiviral therapy are enrolled. All the patients will receive original antiviral treatment for the following 10 years. Patients will be assessed at baseline and at every six months for blood count, liver function test, alpha fetoprotein (AFP), prothrombin time, liver ultrasonography, liver stiffness measurement (LSM), Hepatitis B virus (HBV) DNA and HBV serological markers. HBV-related endpoint events, including cirrhosis decompensations (ascites, esophageal variceal bleeding and hepatic encephalopathy), hepatocellular carcinoma (HCC), liver transplantation and liver-related death, will be collected during follow-up.
It remains unknown whether antiviral therapy is beneficial for chronic hepatitis B (CHB) with normal or mild ALT.The investigators aim to evaluate the antiviral indications combining liver biopsy and clinical parameters,and further clarify the response indexes of clinical results such as virological, serological, biochemical and histological responses from a retrospective observational cohort study on antiviral therapy in HBeAg positive and negative patients with different ALT levels,especially when ALT lower 2 times upper limit of normal (ULN).
Treatment of multidrug resistant (MDR) chronic hepatitis B (CHB) is still a challenging issue. Hence, the investigators will perform a multicenter prospective cohort study for the evaluation of tenofovir disoproxil fumarate (TDF)-based therapy for MDR CHB at real life settings.
The study was conducted to observe the clinical features during pregnancy in women with chronic hepatitis B virus infection and mother-to-child transmission of hepatitis B virus.
