drug_description
A bispecific T-cell engager (BiTE) antibody construct that binds CD19 on B-ALL cells and CD3 on T cells to redirect T-cell cytotoxicity against CD19-positive leukemic blasts.

Blinatumomab
nci_thesaurus_definition
A recombinant, single-chain, anti-CD19/anti-CD3 bispecific monoclonal antibody with potential immunostimulating and antineoplastic activities. Blinatumomab possesses two antigen-recognition sites, one for the CD3 complex, a group of T cell surface glycoproteins that complex with the T cell receptor (TCR), and one for CD19, a tumor-associated antigen (TAA) overexpressed on the surface of B cells. This bispecific monoclonal antibody brings CD19-expressing tumor B-cells and cytotoxic T lymphocytes (CTLs) and helper T lymphocytes (HTLs) together, which may result in the CTL- and HTL-mediated cell death of CD19-expressing B-lymphocytes.

drug_mechanism_of_action
A BiTE antibody construct that simultaneously binds CD19 on B-lineage cells and CD3 on T cells, physically bridging T cells to CD19+ targets to trigger T-cell activation and cytolytic killing (perforin/granzyme–mediated) of CD19-expressing leukemic blasts independent of native TCR specificity.
