Brief summary: Adult patients with r/r acute lymphoblastic leukemia (ALL) (stratum I), r/r Non-Hodgkin's lymphoma (NHL) including chronic lymphocytic leukaemia (CLL), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) or mantle cell lymphoma (MCL) (stratum II) as well as paediatric patients with r/r ALL (stratum III) will be treated with autologous T-lymphocytes transduced by the third-generation RV-SFG.CD19.CD28.4-1BBzeta retroviral vector. The main purpose of this study is to evaluate safety and feasibility of escalating CD19.CAR T cell doses (0,1-20×20\^7 transduced cells/m\^2) after lymphodepletion with fludarabine and cyclophosphamide.
