Active clinical trials for "Hepatitis B, Chronic"

Chronic hepatitis B is a global public health problem, with nearly 700,000 deaths each year because of hepatitis B-related diseases. Recent studies have found that some patients who have used nucleot(s)ide analogues(NAs) for some period can achieve higher hepatitis B surface antigen(HBsAg) clearance rate(which is called clinical cure or functional cure) by using pegylated interferon. Patients who achieve clinical cure will further reduce liver inflammation, fibrosis and risks of liver cirrhosis and cancer in the future. This study was initiated in May 2018 and plans to recruit 30,000 eligible patients. The enrollment conditions are as follows: 1. according with the diagnosis of chronic hepatitis B in the guideline of China in 2015; 2.18-60 years old; 3. more than 1 year history of NAs therapy with HBsAg ≤1500 IU/ml, negative hepatitis e antigen and hepatitis B virus DNA<100 IU/ml; 4. no contraindications of interferon. For the above patients, pegylated interferon was used for 1-2 years(combined with NAs for at least 3 months).The primary goal of this study is to find out the optimal treatment for clinical cure.

Previous studies have shown that there are alterations in the number and affinity of interferon receptors during interferon therapy and that such alterations recover to varying degrees some time after the end of treatment. It can be conjectured that the rest period of pulsed therapy facilitates the recovery of type I interferon receptors and thus the next round of IFN therapy compared to a continuous regimen of interferon.

In this study we will prospectively stop NA in both Caucasian and non-Caucasian patients matched for gender and age, to validate the observed host and viral parameters for future roll-out of this treatment strategy.

This is an open-label, multicenter, randomized, active control study, comparing P1101 monotherapy to entecavir monotherapy in patients with HBeAg-negative chronic hepatitis B under long-term nucleos(t)ide analogue therapy.

In June 2021, Chinese Food and Drug Administration approved the launch of the self-developed new drug Tenofovir Amibufenamide(TMF). TMF is a new second generation of tenofovir(TFV) and its effect on blood lipids is unclear. Our study aims to figure out the effect of TMF on serum lipid level in the process of antiviral therapy for chronic hepatitis B patients.

In Taiwan, HBV infection is endemic in the adult population. With the westernization of eating habit and lifestyle, metabolic syndrome and related non-alcoholic fatty liver diseases (NAFLD, newly proposed as metabolic dysfunction associated fatty liver diseases, MAFLD) has become another important health issue. It is therefore common to encounter subjects with concurrent MAFLD and HBV infection in HBV endemic countries. This project will study the clinical data of patients with concurrent MAFLD and HBV, and aim to explore the impact of exercise intervention on the hepatic fatty infiltration, alteration of gut microbiota and HBV replication status in this group of patients. The research strategies will include (1) improving fatty liver and metabolic syndrome in subjects with concurrent MAFLD and HBV; and (2) exploring the changes of HBV replication and intestinal microflora in patients with concurrent HBV and MAFLD after exercise intervention.

This study aims to investigate the efficacy and safety of avatrombopag for treating thrombocytopenia in hepatitis b virus related acute-on-chronic liver failure patients receiving artificial liver support system treatment.

The purpose of this study is to evaluate the efficacy and safety of Tenofovir alafenamide (TAF) for prevention of mother-to-child transmission of hepatitis B virus among pregnant women with high level HBV DNA.

The study is being conducted to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of HRS-5635 in healthy adults and chronic hepatitis B. To explore the reasonable dosage of HRS-5635.

Multicenter, Prospective Open-label Single Arm Trial Chronic hepatitis B male and female adults on antiviral treatment for hepatitis B, without cirrhosis who are currently HBV DNA (-) and HBeAg (-) To evaluate the safety and efficacy of stopping long-term antiviral therapy in chronic hepatitis B patients without cirrhosis who are currently HBV DNA (-) and HBeAg (-)
