Brief Summary

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

This is a multi-center clinical study in China using CliniMACS TCRα/β+ and CD45RA+ T cell depleted stem cell grafts from haploidentical donors for hematopoietic stem cell transplantation in children.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This clinical study will the CliniMACS TCRα/β and CD45RA Systems to deplete TCRα/β+ and CD45RA+ cells from the mobilized peripheral blood stem cells of a haploidentical donors to treat pediatric patients who were suffuring form relapsed or refactory leukemia.

Aming to evaluate the safety/tolerability and feasibility of haploidentical PBSC grafts depleted of TCRα/β+ and CD45RA+ cells using the CliniMACS TCRαβ/CD45RA System in pediatric patients with hematological malignancies diseases. And the incidence of grade II-IV acute graft-versus-host disease (GVHD) until Day 100 post-transplantation of this new In Vitro T cell depletion technology in China.

The investigators will monitor the incidence of grade I acute GVHD until Day 100 post-transplantation, incidence and severity of chronic GVHD after 1 year and 2 years, incidence of NRM at all visits throughout the study, and graft failure from Day 0 to Day 28 at the same time.
