A Study of Peginterferon Alfa-2b Combined With TDF in Patients With Chronic Hepatitis B

A Multi-center, Randomized, Blinded Study to Evaluate the Efficacy and Safety of Peginterferon Alfa-2b Injection Combined With Tenofovir Disoproxil Fumarate Tablets in Patients With Chronic Hepatitis B

Current clinical practices has shown promising prospects of the therapy strategy of interferon combined with nucleos(t)ides in patients with chronic hepatitis B, but the safety and efficacy has not been fully studied. This study is aimed to exploit the safety and efficacy of the study drug, Peginterferon alfa-2b injection, with nucleos(t)ide (NAs), tenofovir disoproxil fumarate tablets (TDF), in the patients with hepatitis B, who has previously treated with nucleos(t)ides and who are treatment naïve.
