The Clinical Cure Project of Chronic Hepatitis B in China

April 9, 2025 updated by: Zhiliang Gao, Third Affiliated Hospital, Sun Yat-Sen University

A Study of Peg-interferon Treatment for Nucleos(t)Ide Analogues Suppressed Chronic Hepatitis B Patients With Low Level Hepatitis Surface Antigen

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.
