Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a randomized, prospective, comparative study of the effectiveness of prophylactic entecavir treatment for HBV reactivation in past HBV infected patients (HBsAg-, HBcIgG+) with allogeneic hematopoietic stem cell transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a randomized, prospective, comparative study of the effectiveness of prophylactic entecavir treatment for HBV reactivation in past HBV infected patients (HBsAg-, HBcIgG+) with allogeneic hematopoietic stem cell transplantation.

In this study, patients are randomized into treatment group or delayed treatment group.

\* Stratified randomization (Block randomization within strata) according to the presence of HBsAb at baseline was used in this study.

1. Experimental: Treatment group (n=113) The intervention group take entecavir 0.5mg everyday by oral administration for 3 years after allogeneic hematopoietic stem cell transplantation. The intervention group visit clinic every month and examined liver function test, HBsAg/Ab. HBV DNA level is examined at every 3 months.

\* oral administration of entecavir is planned to start within 7 days after hematopoietic stem cell transplantation.
2. No Intervention: delayed treatment group (n=113) The delayed treatment group visit clinic every month and examined liver function test, HBsAg/Ab. HBV DNA level is examined at every 3 months. If the patient in the delayed treatment group shows HBV reactivation (positive HBsAg or HBV DNA ≥10 IU/mL), entecavir treatment is started.

Study Groups

Treatment group

The intervention group take entecavir 0.5mg everyday by oral administration for 3 years after allogeneic hematopoietic stem cell transplantation. The intervention group visit clinic every month and examined liver function test, HBsAg/Ab. HBV DNA level is examined at every 3 months.

Group Type EXPERIMENTAL

Baracle Tab.®

Intervention Type DRUG

The intervention group take entecavir 0.5mg everyday by oral administration for 3 years after hematopoietic stem cell transplantation.

delayed treatment group

The delayed treatment group (control group) visit clinic every month and examined liver function test, HBsAg/Ab for 3 years after allogeneic hematopoietic stem cell transplantation. HBV DNA level is examined at every 3 months for 3 years after allogenic hematopoietic stem cell transplantation. If the patient in the delayed treatment group shows HBV reactivation (positive HBsAg or HBV DNA ≥10 IU/mL), entecavir treatment is started.
