Clinical Study on CD20 Monoclonal Antibody for Preventing Early EB Virus Activation After Allogeneic Hematopoietic Stem Cell Transplantation

2026年11月5日 更新者:CHEN Jia、The First Affiliated Hospital of Soochow University

Efficacy and Safety of B-cell Clearance in Preventing Early Epstein-Barr Virus Activation After Allogeneic Hematopoietic Stem Cell Transplantation: A Multicenter, Prospective, Randomized Controlled Clinical Study

The main purpose of this study is to evaluate the preventive effect and safety of CD20 monoclonal antibody clearing B cells on EBV activation 180 days after allogeneic hematopoietic stem cell transplantation. The study will also observe the effects of this strategy on EBV-PTLD, CMV reactivation, hematopoietic reconstruction, acute and chronic graft-versus-host disease (GVHD), non recurrent death, recurrence, survival, and post transplant immune reconstruction.

In this study, CD20 monoclonal antibody was used for the prevention of EBV activation after transplantation, which is an investigational prophylactic drug/beyond the indications stated in the instructions. The research doctor will explain the relevant basis, potential benefits, and potential risks to you during the informed consent process.

The research subjects were patients who received their first allogeneic hematopoietic stem cell transplantation in each enrolled transplantation center. After evaluating the inclusion and exclusion criteria and signing the informed consent form, they were randomly divided into an experimental group and a control group at a 1:1 ratio. The experimental group received prophylactic CD20 monoclonal antibody treatment (dose of 375mg/m2, intravenous application, once) 5 days after transplantation; If medication cannot be administered on time due to special clinical circumstances, it can be completed within 5 to 30 days after transplantation. The control group did not receive prophylactic CD20 monoclonal antibody within 30 days after transplantation, and EBV-DNA, CMV-DNA, and transplant related complications were monitored according to the routine procedures of the center. All subjects were followed up according to the protocol until 2 years after transplantation or death/loss to follow-up/withdrawal of informed consent. Primary endpoint evaluation will be conducted 180 days after transplantation, and continuous collection of PTLD, CMV reactivation, hematopoietic reconstruction, etc. will be conducted GVHD、 Data on recurrence, survival, safety, and immune reconstitution. Among them, allogeneic hematopoietic stem cell transplantation, routine blood routine/liver and kidney function tests, EBV-DNA/CMV-DNA monitoring, infection and GVHD management are procedures that need to be performed for diagnosis and treatment; Randomized grouping, prophylactic CD20 monoclonal antibody administration in the experimental group, data collection, and protocol specified follow-up are the relevant procedures of this study.
