Brief Summary

The risk of Graft-versus-host Disease(GVHD) is significantly associated with the mortality rate of patients undergoing allogeneic hematopoietic stem cell transplantation. The occurrence of GVHD increases the hospitalization rate and economic burden of patients. In order to explore better methods for controlling GVHD, we designed a clinical trial using CD25 monoclonal antibody for GVHD prevention. Our previous studies have shown that reduced-dose anti-thymocyte globulin(ATG) in the conditioning regimen can achieve the same effect as full-dose ATG. Here, we try to explore the preventive effect of CD25 antibody on acute and chronic GHVD under low-dose ATG pretreatment condition.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Patients with a clear diagnosis of hematologic disease, weighing ≥30kg, aged 18-60, of any gender and race;
  • Willing to undergo haploidentical hematopoietic stem cell transplantation;
  • Voluntarily participate in this study;
  • Each subject must sign an informed consent form (ICF) indicating their understanding of the purpose and procedures of the study, and their willingness to participate. Considering the patient 's condition, if the patient' s signature is unfavorable for disease treatment, the informed consent form should be signed by the legal guardian or the patient 's immediate family member.

You may not qualify if:

  • Those with severe organ dysfunction or diseases, such as heart, liver, kidney, and pancreatic diseases;
  • Patients who cannot tolerate CD25 monoclonal antibody treatment;
  • Subjects and/or authorized family members who refuse allo-HSCT treatment;
  • Any life-threatening diseases, physical conditions, or organ system dysfunctions that the researcher believes may jeopardize the safety of the subject and pose unnecessary risks to the study; drug dependence; uncontrolled mental illness in subjects; cognitive dysfunction;
  • Those who have participated in other similar clinical studies within the past 3 months;
