Mechanism of Action of BiTE Immunotherapy

Author(s)Joshua K. Sabari, MD

Joshua K. Sabari, MD, discusses how tarlatamab, a BiTE, demonstrates a unique mechanism of action by targeting DLL3, which is aberrantly expressed in 85% to 94% of SCLC cells, thereby directing T cells to these cancer cells independently of MHC class I and promoting T-cell–mediated tumor lysis and regression.
