Brief Summary

Graft-versus-host disease (GVHD) is an important complication after transplantation, with an incidence of 40-60%, which can increase non-relapse mortality if poorly controlled. At present, the standard prophylaxis for GVHD is cyclosporine combined with methotrexate. However, calcineurin inhibitors (CNI) can cause some vital side effects, which are not tolera...
