Summary

Acute graft-versus-host disease remains a major complication after haploidentical hematopoietic stem cell transplantation. Methotrexate is commonly used as part of graft-versus-host disease prophylaxis, but it may be associated with delayed hematopoietic recovery and transplant-related toxicities, including oral mucositis.

This is a prospective, multicenter, randomized, open-label, parallel-controlled Phase III clinical trial designed to evaluate an anti-CD25 monoclonal antibody regimen compared with methotrexate for the prevention of acute graft-versus-host disease after haploidentical hematopoietic stem cell transplantation. Eligible patients with hematologic malignancies scheduled to undergo haploidentical allogeneic hematopoietic stem cell transplantation will be randomly assigned in a 1:1 ratio to receive either methotrexate-based prophylaxis or anti-CD25 monoclonal antibody-based prophylaxis, in combination with standard graft-versus-host disease prophylaxis including anti-thymocyte globulin, calcineurin inhibitor, and mycophenolate mofetil.

The primary objective is to compare 12-month graft-versus-host disease-free, relapse-free survival between the two groups. Secondary objectives include comparison of acute graft-versus-host disease, chronic graft-versus-host disease, oral mucositis, hematopoietic recovery, cytomegalovirus and Epstein-Barr virus reactivation, infection, relapse, non-relapse mortality, overall survival, and leukemia-free survival.

Conditions

Interventions

DRUG

Methotrexate

Methotrexate will be administered intravenously at 15 mg/m² on Day +1 and 10 mg/m² on Days +3, +6, and +11 after haploidentical hematopoietic stem cell transplantation for graft-versus-host disease prophylaxis.

BIOLOGICAL

Anti-CD25 Monoclonal Antibody

Anti-CD25 monoclonal antibody, also described as daclizumab in the protocol, will be administered intravenously at 1 mg/kg on Day 0 and Day +4 after haploidentical hematopoietic stem cell transplantation for graft-versus-host disease prophylaxis. The Day 0 dose will be administered 2 hours before stem cell infusion.
