Summary

To assess the efficacy and safety of using recombinant humanized anti-CD25 monoclonal antibody injection as a prophylactic strategy for reducing the incidence of severe acute graft-versus-host disease (aGVHD) in adult patients at intermediate to high risk, as predicted by the dynamic aGVHD Onset Anticipation Tianjin (daGOAT) model, following allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Conditions

  • Acute Graft-versus-Host Disease

Interventions

DRUG

Recombinant Humanized Anti-CD25 Monoclonal Antibody Injection

Model-predicted patients at high risk (HR): Recombinant humanized anti-CD25 monoclonal antibody: 50 mg/day when the post-transplant model predicts high risk in the second week post-prediction and 25 mg/day in the fourth and sixth weeks post-prediction. Administered in combination with conventional aGVHD prevention regimen. Model-predicted patients at moderate risk (MR): Recombinant anti-CD25 humanized monoclonal antibody: 25 mg/day when the model predicts intermediate risk post-transplantation and at the 2nd, 4th, and 6th weeks post-prediction. Administered in combination with conventional aGVHD prevention regimen. Model-predicted patients at low-risk (LR): A conventional aGVHD prevention regimen only was used.
