The purpose of this study is to evaluate the efficacy in terms of hepatitis B surface antigen (HBsAg) levels of the study intervention (that is, JNJ-73763989 + JNJ-56136379 + nucleos[t]ide analog [NA] and pegylated interferon alpha-2a [PegIFN-alpha2a].


This study is an intervention specific appendix to the Hepatitis B wings platform trial (PLATFORMPAHPB2001).
