Filter by:This is a Phase4, multicenter, open-label, randomized study to demonstrate that the Tenolid Tab switching group is non-inferior to the virologic suppression effect compared to the Viread Tab continuous administration group and evaluate the safety of Tenolid Tab. This clinical trial was conducted on patients who were taking Viread Tab as monotherapy for more than 48 weeks for chronic hepatitis B. At the time of screening(Visit 1), information on factors related to medical history and prognosis including Viread Tab administration were collected retrospectively from the subjects who voluntarily signed the informed consent form (ICF). Only subjects who are determined to be suitable for the study eligibility(inclusion/exclusion) criteria as a result of the screening evaluations are randomized in a 1:1 ratio to one of the two groups at the baseline. Subjects will receive investigational product start on the next day of randomization for 48 weeks. Subjects will visit to the study site on 12, 24, 36, 24 weeks after starting dosing investigational product and evaluated for effectiveness of virologic suppression and safety.
This study will assess the safety, efficacy and immune response following the sequential treatment of GlaxoSmithKline's (GSK) ASO compound (GSK3228836) and CHB-TI (GSK3528869A) in participants 18 to 65 years stable on NA treatment for CHB. The aim is to quantify the efficacy of sequential therapy as well as to determine an added value of sequential therapy over GSK3228836 therapy in CHB patients treated with NAs. In addition, the study will assess the effect of different treatment durations of GSK3228836 (12 or 24 weeks) prior to initiating GSK3528869A treatment.
The purpose of this study is to evaluate efficacy of the study intervention, based on hepatitis B surface antigen (HBsAg) levels at follow-up (FU) Week 24.
This is a drug-drug interaction study conducted in healthy volunteers to evaluate the effect of HRS5091 on CYP3A4, CYP2C9, CYP2C19, P-gp, BCRP and OATP1B1, using midazolam, s-warfarin, omeprazole, digoxin and rosuvastatin as probe drugs.
This study is a randomised, controlled, unblinded, clinical intervention trial consisting of 12 weeks of aerobic exercise training. Thirty persons with chronic hepatitis B (CHB) and hepatic steatosis are randomised to either aerobic exercise training (intervention group, n=15) or no intervention (control group, n=15). The study will investigate the effects of the exercise intervention on the liver and the hypothesis is that the exercise group will reduce the fat-fraction of the liver after the intervention.
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.
In the globe, about 33% (2 billion) of population has ever been infected with hepatitis B virus (HBV), and about 5% (350-400 million) were chronical HBV infection. In areas with high prevalence of hepatitis B, up to 80% of primary liver cancers are associated with HBV infection. About 25% of chronic hepatitis B virus carrier (more than 1 million people per year) eventually die of end stage liver disease associated with HBV infection, such as liver failure associated with cirrhosis and hepatocellular carcinoma. HBV replicates in the liver, which increases the risk of hepatocellular carcinoma in HBV carriers. Studies have shown that the risk of hepatocellular carcinoma (HCC) in HBV carriers was 10-100 folds higher than that of non-carriers. Clinically, there are primarily two types of antiviral drugs: α-interferons (plain and pegylated ([PEG-IFN]α-2a or α-2b) interferons) and nucleos(t)ide analogues (NUC) including lamivudine (LAM), adefovir dipivoxil (ADV), entecavir (ETV), telbivudine (LDT), tenofovir disoproxil fumarate(TDF) and tenofovir alafenamide fumarate(TAF). With the development and application of antiviral drugs in recent years, the basic goal of maintain suppression against virus replication has been achieved, and HBsAg loss is considered as function cure of antiviral therapy. However, data from clinical studies showed a very low cure rate of current antiviral drugs and a natural HBsAg loss usually is less than 3%. The vast majority of clinical patients require long-term antiviral treatment and have difficulties in treatment stop. The AI data mining system innovated by the Holy Haid owns a ten-million-scaled database and utilizes dozens of HBV-associated targets to identify 100 drugs that are most closely to the targets among the 500 commercially available drugs. With the identified 100 drugs, Holy Haid (Ying-ying Li) and Beijing Tsinghua Changgung Hospital (Lai Wei) conducted a cytological verification in mice, which indicated that the HD042 (Celecoxib) at 20uM concentration can inhibit HBV DNA, HBsAg and HBeAg by 70.87%, 88.52% and 87.55% respectively, without significant cytotoxicity. Based on this, Beijing Tsinghua Changgung Hospital (Lai Wei) retrospectively analyzed 1,114,661 patients admitted to 304 hospitals in 107 cities of 21 provinces and municipalities from January 1, 2019 to October 31, 2020 and identified 19,692 patients with the results of two HBsAg tests available and an interval of over 30 days. Among these, 3,359 patients had ever took HD042 (Celecoxib). Further analysis showed that these 3,359 patients, and screened out 383 patients who were diagnosed of hepatitis B and excluded from tumor with two HBsAg levels > 0.05IU/ml but ≤1500IU/ml. Among these, 110 patients were prescribed for more than 5 Celecoxib doses (about 30 days of treatment). Among the 110 patients, we screened out 27 patients on Celecoxib for 12 weeks whose HBsAg expression decreased by 59.2% after 12 weeks, including HBsAg clearance rate (i.e., HBsAg decreased to < 0.05IU/ mL) up to 18.5%. Celecoxib, a specific inhibitor of Cyclooxygenase 2 (COX-2), has been widely used in clinical practice as an anti-inflammatory and analgesic drug. Studies have shown that Celecoxib improves NASH by inhibiting inflammatory responses. In addition, some studies have also shown that COX-2 is highly expressed in hepatitis B related hepatocellular carcinoma, resulting in cancerous tissue microangiogenesis. Cytological test found that Celecoxib, as a COX-2 specific inhibitor, can inhibit the growth of liver cancer cells by induced apoptosis and cell cycle inhibition, and have a even stronger effect on HBsAg positive liver cancer cells. However, the inhibitory effect of Celecoxib on the hepatitis B surface antigen in patients with chronic hepatitis B remained controversial. Therefore, this study is designed to investigate the safety and efficacy of Celecoxib in the hepatitis B surface antigen loss and reduction in nucleoside-treated patients with chronic hepatitis B.
This is a prospective/retrospective, observational follow-up study of effects of fatty liver on chronic hepatitis B. Patients will join this study who undergo transient elastography with liver stiffness (LS) and CAP measurements or Ultrasonic examination. All recruited subjects will undergo comprehensive clinical, anthropometric and laboratory assessments at the time when transient elastography or Ultrasonic examination is performed. We plan to compare the relationship between chronic hepatitis B and non-alcoholic fatty liver disease. Patients will be divided into several groups based on the demand.
The study is designed to assess efficacy of a finitie treatment in Chronic Hepatitis B patients who had stable treatment of NAs for ≧ 2 years， which is compared hepalatide in combination with Pegylated Interferon + TAF with Pegylated Interferon +TAF. Subjects will be randomly assigned to the hepalatide or placebo groups , 15 subjects in each group . Subjects will receive hepalatide+Pegylated Interferon +TAF treatment for 48 weeks or placebo +PegylatedInterferon +TAF treatment for 48 weeks , Then, stopping all treatments and followed with further 24 weeks follow-up.
The purpose of the study is to characterize the pharmacokinetic (PK) profile of cetrelimab administered subcutaneous (SC) and optionally intravenous (IV) in chronic hepatitis B (CHB) participants.
