Introduction: | Blinatumomab is a BiTE-class (bi-specific T-cell engager) constructed monoclonal antibody formed by the recombinant fusion of an anti-CD3 single-chain variable fragment (scFV) and an anti-CD19 scFV through a short peptide linker. CD3 is an antigen expressed on the surface of T-cells, while CD19 is mostly expressed on the surface of malignant B-cells. Since blinatumomab has an affinity to both antigens, it redirects T-cells to tumor cells expressing CD19 and promotes tumor cell lysis and apoptosis. Blinatumomab is manufactured by Amgen Inc. and marketed under the brand Blincyto. It was first approved by the FDA in December 2014 for the treatment of CD19-positive B-cell precursor acute lymphoblastic leukemia (ALL) in relapsed and refractory patients. In March 2018, it was approved under the FDA's accelerated approval program for the treatment of CD19-positive B-cell precursor ALL in first or second complete remission with minimal residual disease (MRD) greater than or equal to 0.1% in adults and children. Full approval for this indication was granted in June 2023. Blinatumomab has a short half-life, requiring patients to receive a continuous infusion over 4-week cycles using a portable mini-pump for optimum delivery. |
