A Randomized Controlled Trial of Prophylactic Rituximab to Reduce Clinically Significant EBV DNAemia After Allogeneic Hematopoietic Stem Cell Transplantation
Starting soon · Not applicable
Conditions studied: Allogeneic Hematopoietic Stem Cell Transplantation, Epstein-Barr Virus Reactivation, Clinically Significant EBV DNAemia
In brief
This is a single-center, prospective, randomized, open-label clinical trial with blinded endpoint assessment for patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT). We aim to explore whether low-dose preventive rituximab can lower the risk of clinically significant Epstein-Barr virus (EBV) viremia within 180 days after transplantation. Patients aged 16-65 years who receive allo-HSCT and carry medium-to-high risks of EBV reactivation will be enrolled. All eligible participants will be randomly split into two groups at day +21 after transplant at a 1:1 ratio. Intervention group: Standard post-transplant supportive care plus two low doses of rituximab (100mg intravenous infusion on day +21 and day +28). Control group: Only standard routine post-transplant management without preventive rituximab. All participants will receive regular scheduled blood tests and outpatient follow-up visits up to 1 year after transplantation. We will monitor EBV viral load, cytomegalovirus (CMV) infection, graft-versus-host disease (GVHD), infection complications, immune function recovery, as well as long-term survival. We will also record all adverse reactions related to rituximab infusion, low immunoglobulin levels and other safety events. The main study outcome is the cumulative rate of clinically significant EBV viremia within 180 days post transplant. All endpoint judgments will be completed by independent researchers to reduce assessment bias. This trial hopes to confirm the safety and clinical value of low-dose rituximab prevention, and provide reliable clinical evidence for EBV infection prevention after hematopoietic stem cell transplantation.
