Allogeneic CART-NKG2D cells(IdiPAZ)

The goal of this clinical trial is to test the feasibility and safety of an academic production of two different anti-CD19 chimeric antigen receptor T cells (CART) products according to the different biomarkers of the disease in children and young adults with relapsed/refractory CD19+ B cell acute lymphoblastic leukemia (r/r B-ALL) or relapsed/refractory T-cell acute lymphoblastic leukemia (r/r T-ALL). The main questions it aims to answer are:
1. The safety and feasibility of autologous CART-19/22 in children, adolescents and young adults with a CD19+/- CD22+ relapse/ refractory disease for a r/r B-ALL.
2. The safety and feasibility of allogeneic CART-NKG2D (chimeric-antigen receptor Natural-killer group 2, member D) in children, adolescents and young adults with r/r T-ALL.
