Targeted Therapy Agent

**Semantic type:** Chemical Viewed Functionally

**Definition:** Any agent that specifically targets or interferes with the synthesis or function of a molecule that is expressed specifically in or on cells of the tumor and/or the tumor microenvironment (TME), such as immune cells or surrounding blood vessels. The targeted molecule is usually overexpressed or mutated in tumors but minimally or not expressed by normal, healthy tissues; additionally, expression is typically associated with tumor cell proliferation, progression and/or survival. By blocking the function or expression of the tumor-associated target, the targeted therapy agent may exert potential antineoplastic and/or immunomodulatory activities.
