简要总结
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.
详细描述
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.
- 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.

结局指标
主要结局
Comparison of the rate of HBV reactivation between the treatment and delayed treatment groups.
时间窗: The primary outcome is evaluated during 3 years after hematopoietic stem cell transplantation
Comparing the rate of HBV reactivation between the treatment and delayed treatment groups during 3 years after hematopoietic stem cell transplantation \* Definition of HBV reactivation: HBsAg ≥ 1.0 S/CO or HBV DNA ≥ 10 IU/mL
次要结局
- Comparison of the rate of active hepatitis with HBV reactivation between the treatment and delayed treatment groups.(The secondary outcomes are evaluated during 3 years after hematopoietic stem cell transplantation.)
- Comparison of the rate of survival related to HBV reactivation between the treatment and delayed treatment groups.(The secondary outcomes are evaluated during 3 years after hematopoietic stem cell transplantation.)
- Comparison of the rate of hepatic failure related to HBV reactivation between the treatment and delayed treatment groups.(The secondary outcomes are evaluated during 3 years after hematopoietic stem cell transplantation.)
