Patients who are HBcAb-positive, HBsAg-negative, and HBV DNA-negative should receive appropriate antiviral preventive treatment during the study. Patients who are positive for hepatitis C antibodies should have negative PCR results, and those with positive PCR results will be excluded. However, the salvage cohort group does not require preventive treatment. For safety, patients will continue active anti-HBV treatment with HBV DNA tests performed every 3 months until at least 6 months after completion of hie/her study participation. HBV DNA will be tested by PCR. 27.

Patients with a history of stroke will be eligible if he/she has been without a stroke or transient ischemic attack in the past 2 years and no neurological deficits. However, patients with CNS involvement but there is no relevant CNS disease or patients who have not experienced related symptoms may be eligible. In addition, if there is CNS involvement, but registration in the main cohort is possible, registration in the main cohort can be done after discussion with the state responsible agency. In addition, patients with CNS involvement but there is possible to register in the main cohort, it can be registered in the main cohort after discussion with the investigator of mainstudy site. 30.
