The main questions it aims to answer are:\n\n1. 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.\n2. 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.', 'detailedDescription': 'Incredible progress has been made in the treatment of relapsed/refractory CD19+ acute lymphoblastic leukemia (r/r ALL) by the application of anti-CD19 chimeric antigen receptor (CAR) T cells (CART19). However, equivalent progress has not been achieved in the treatment of relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL). Furthermore and although the majority of patients with CD19+ r/r ALL respond to CART19, 30-60% of patients relapse after this treatment, probably due to the short persistence of CAR T-cells and the immune escape or down-regulation of CD19 antigen. Patients with relapsed ALL after CART19 have a very poor prognosis and novel treatment approaches are urgently needed. To date, both relapse after CART19 malignancies and T-ALL represent an unmet medical need where no effective or targeted therapies currently exist. Recently, we and other groups have reported how T-ALL and acute myeloid leukemia (AML) cell lines were more sensitive to CART-NKG2D (chimeric-antigen receptor Natural-killer group 2, member D) cytotoxicity than B-ALL cell lines. We have previous experience in the production and administration, under compassionate use, of CART cells targeting dual CD19/CD22 antigens and NKG2D ligands. In this context, this phase I clinical trial is designed to test the feasibility and safety of an academic production of two different CART products according to the different biomarkers of the disease.\n\nIn the present study (ReALL\\_CART), we propose an umbrella design methodology using autologous dual CART-19/22 for CD19+/-CD22+/- relapse after CART19 or allogeneic CART-NKG2D for NKG2DL+ r/r T-ALL.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '30 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* ARM A: CD19+/- CD22+ B-ALL with relapsed or refractory disease not responding to conventional chemotherapy and with no other curative therapy available.
