NCT ID: NCT05792878 Recruiting - Chronic Hepatitis B Clinical Trials

Study of COVID-19 Infection and Its Clinical Prognosis in Chronic Hepatitis B Patients With Antiviral Therapy

Start date: September 1, 2022
Phase:
Study type: Observational

This is a two-way (retrospective and prospective) study of COVID-19 infection in an observational cohort of patients with chronic hepatitis B treated with antiviral therapy. Patients with chronic hepatitis B who received anti-HBV treatment in the Second Department of Hepatology, Beijing Ditan Hospital Affiliated to Capital Medical University from February 2022 to December 2023 were enrolled. After enrollment, demographic data of patients, information on antiviral treatment of chronic hepatitis B, COVID-19 vaccination, COVID-19 infection and COVID-19 incidence and treatment from January 2022 to pre enrollment, and data on HBV virus and serology, clinical biochemistry, liver and lung imaging, COVID-19 nucleic acid and COVID-19 antibody examination of patients were collected. After enrollment, prospective anti-HBV treatment, HBV virology, clinical biochemistry, liver imaging and COVID-19 infection and morbidity were observed. The patients with COVID-19 infection during the prospective observation period were observed for COVID-19 infection, onset and treatment, including body temperature, clinical symptoms, signs, cardiac examination, pulmonary imaging, COVID-19, clinical biochemistry, disease severity, time of virus negative conversion, hospital stay and outcome. The influence of COVID-19 infection on liver disease and the influence of interferon anti-HBV treatment on COVID-19 infection, its pathogenesis and prognosis were studied.

A Novel Combination Therapeutic Strategy Aiming to Functional Cure for Chronic Hepatitis B Virus Infection (Sustained HBsAg Loss) (B)

Start date: June 1, 2023
Phase: Phase 4
Study type: Interventional

Hepatitis B virus (HBV) infection is a major public health threat in China. At present, a functional cure, also known as clinical cure or sustained Hepatitis B surface antigen (HBsAg) loss, is recommended as the ideal endpoint of HBV treatment. However, HBsAg loss can be achieved in less than 10% of chronic hepatitis B (CHB) patients treated with current available antiviral drug interferon (IFNα) or nucleos(t)ide analogues (NAs) monotherapy. With the support of the national major special funding for infectious diseases from "11th Five-Year Plan" to "13th Five-Year Plan", we have implemented a pioneer clinical study of sequential combination of IFNα therapy on NAs to treat NAs-treated CHB patients (ie. New Switch Study). This is the world's first clinical trial aiming to functional cure, which increased the rate of HBsAg loss to 15% in the overall population in our study, and to 30-50% among those with lower baseline HBsAg levels. How to further improve the HBsAg loss rate is an urgent issue for us. The key point of achieving functional cure is to reverse the HBV-specific T cell exhaustion and establish the long-term immune control against HBV infection. (Programmed death-1) PD-1/programmed death-ligand 1 (PD-L1) axis blockade has been demonstrated to reinvigorate exhausted CD8+ T cells, and would be a potential strategy to treat chronic HBV infection. In this study, a large multicenter prospective study will be performed to explore the safety and efficacy of a novel combination strategy involving immune checkpoint inhibitor (anti-PD-1 antibody) and IFNα in CHB patients, observe the HBsAg loss rate in NA-treated CHB patients receiving this combination strategy, evaluate the potential of breaking immune tolerance by this strategy, and further assess its efficacy to further improve the clinical cure rate on the basis of New Switch Study. Based on New Switch Study, this study further attempts to reverse T cell exhaustion in CHB patients, explore a novel platform of combination therapy development for clinical cure, and ultimately increase the HBsAg loss rate to higher than 50% in overall patients. The implementation of the project is expected to reduce the burden of HBV infection in China and contribute to the goal of global elimination of hepatitis B and C by 2030 (WHO 2030).

NCT ID: NCT05766449 Recruiting - Clinical trials for Non-alcoholic Fatty Liver Disease

Risk Factors for Hepatic Inflammation, Fibrosis and Prognosis in Patients With CHB and NAFLD

Start date: June 1, 2022
Phase:
Study type: Observational

Chronic hepatitis B (CHB) affects an estimated 292 million people, and causes approximately 800,000 people deaths per year from liver-related complications including cirrhosis and hepatocellular carcinoma, remaining a major global public health issue.Meanwhile, with the improvement of living standards and changes in lifestyle and dietary habits, non-alcoholic fatty liver disease (NAFLD) has become another important cause of liver cirrhosis and HCC.HBV combined with NAFLD inevitably develops into continuous or intermittent liver inflammation and fibrosis, which greatly increases the risk of cirrhosis, liver cancer and even end-stage liver disease. We aimed to investigate the risk factors and establish diagnostic models for hepatic inflammation, fibrosis in patients with CHB associated NAFLD. In addition, to find risk factors for liver cirrhosis, liver cancer or liver failure in patients with CHB-related NAFLD.

The Efficacy and Safety of Tenofovir Amibufenamide to Treat Low-level Viraemia After Entecavir Treatment

POWER
Start date: March 1, 2023
Phase:
Study type: Observational

The goal of this observational study is to explore the efficacy and safety of Tenofovir Amibufenamide (TMF) in Entecavir (ETV) treated chronic hepatitis B patients with low-level viraemia. The main question it aims to answer is: - The efficacy and safety of TMF in chronic hepatitis B patients with low-level viraemia. - What is the appropriate treatment for ETV treated chronic hepatitis B patients with low-level viraemia. Participants will choose to maintain their original regimen (ETV) or switch to TMF After being fully informed of the benefits and risks of treatment. Researchers will compare ETV and TMF to see if there is a difference in the efficacy of the two drugs in chronic hepatitis B patients with low-level viraemia.
