Market Overview

Solid tumor bispecific immunotherapies are engineered biologics designed to redirect immune cells toward tumor cells by simultaneously engaging two distinct targets. These therapies aim to overcome immune evasion mechanisms inherent to solid tumors. Unlike hematologic cancers, solid tumors present barriers such as heterogeneous antigen expression and immunosuppressive microenvironments. Bispecific formats enable localized immune activation while limiting systemic exposure. Clinical use is concentrated in tertiary oncology centers. The market primarily targets lung, breast, gastrointestinal, and gynecologic cancers.
