Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study plan aims to include patients who have been diagnosed with steroid-refractory chronic GVHD in the liver following allogeneic hematopoietic stem cell transplantation. After obtaining informed consent, the patients will be randomly assigned to either the Anti-CD25 rhMAb treatment group or the traditional treatment group. The objective is to assess the effectiveness and safety of Anti-CD25 rhMAb in the treatment of severe chronic GVHD affecting the liver.
