Comment: Tarlatamab (AMG 757) is a bispecific T cell engager (BiTE®) type anti-Delta-like ligand 3 (DLL3) monoclonal antibody [4-5]. It co-engages DLL3 on cancer cells and CD3E on T cells to promote T cell-mediated tumor lysis. The rationale for investigating DLL3 as a cancer drug target is reviewed in [3].
