CD62L Depleted Donor Lymphocyte Infusion With T Cell Depleted Haploidentical Hematopoietic Stem Cell Transplantation


Sponsor

Hong Kong Children's Hospital

Enrollment

23 participants

Start Date

Sep 1, 2023

Study Type

INTERVENTIONAL

Conditions

Summary

In this clinical trial, the investigators aim to apply CD62L depleted donor lymphocyte infusion (DLI) together with in vitro T cell depleted haploidentical hematopoietic stem cell transplantation (HSCT) to treat patients with malignant or non-malignant disease in need of HSCT. The investigators shall evaluate the graft failure-free, graft-versus-host disease (GVHD)-free survival at one year, frequency of adverse events and post-transplant complications, and immunoreconstitution.


Eligibility

Max Age: 18 Years

Inclusion Criteria3

  • Patient who requires allogeneic hematopoietic stem cell transplant, has no human leukocyte antigen (HLA)-matched sibling donor but has an HLA-haploidentical donor.
  • Adequate organ function to tolerate the conditioning chemotherapy and radiotherapy
  • Karnofsky or Lansky performance status score ≥50

Exclusion Criteria4

  • Pregnant or lactating woman
  • HIV infection
  • Patients for whom alternative treatment is deemed more appropriate by treating physician
  • Patients who are unlikely to benefit from haploidentical hematopoietic stem cell transplantation, e.g., terminal malignancy with multiorgan failure
