Pegylated Interferon α in Previously Interferon-treated CHB（Leading Study）

Recruiting now · Not applicable

Conditions studied: Chronic Hepatitis b

In brief

Previous clinical practice and exploratory studies suggest that some patients who have not achieved functional cure in the first round of interferon therapy can achieve HBsAg clearance by interferon retreatment (intermittent therapy), which can reduce the occurrence of complications such as liver fibrosis, liver cirrhosis and liver cancer, and its clinical benefit is expected to be higher than that of NAs monotherapy. This study is aimed to conduct a large-scale, multicenter, prospective study to confirm the benefit of peginterferon-based therapies in these populations. It expected to enroll about 2000 patients with chronic hepatitis B who have received prior interferon therapy and achieved a good response but without function cure, patients receive either interferon-based therapy or NAs monotherapy, according to their wishes and doctors' professional recommendations, with a ratio of 2:1 between the two groups, and all patients treated for 48 weeks. The HBsAg clearance rate before and after treatment, safety, etc. will be analyzed.
