NCIt synonyms : Blinatumomab-cultured T cells; BET; Blinatumomab-expanded T Cells; Blinatumomab-expanded Peripheral Blood-derived T Cells;
NCIt definition : A preparation of autologous, peripheral blood-derived polyclonal activated T-cells
that have been expanded and activated ex-vivo using blinatumomab and recombinant human
IL2 (rhIL-2) and depleted of contaminating CD19 tumor cells, with potential immunomodulating
activity. Upon administration, these blinatumomab-expanded T-cells (BET), composed
of functional polyclonal CD4 and CD8 T-cells and mostly effector and central memory
cells, may induce immunological recovery. BET cell expansion leads to the lysis and
elimination of contaminating CD19 tumor cells. The elimination of contaminating tumor
cells is important in the treatment of non-Hodgkin CD20 indolent lymphoma (iNHL)
and chronic lymphatic leukemia (CLL).;
