Clinical Trial Summary

Treatment Study to assess of safety and efficiency of T cells receptor (TCR) alfa beta depleted graft for hematopoietic stem cell transplantation (HSCT) from haploidentical and unrelated donors in patients with primary immunodeficiency diseases

Description:

Infections, graft versus host diseases (GVHD) and associated morbidity and mortality remains significant problems after unrelated and haploidentical hematopoietic stem sell transplantation (HSCT) in patients with primary immunodeficiency diseases (PID). In this study the hypothesis is that the transplantation of TCR alfa beta depleted peripheral blood stem cells (PBSC) would offers advantages over the use of positively selected CD34+ stem cells in haploidentical HSCT and non-manipulated graft in unrelated HSCT.

The purpose of this study is to evaluate the safety and efficiency of the selective infusion of TCR alfa beta T cell depleted graft in pediatric patients with PID receiving HSCT from haploidentical and unrelated donors.
