SS1(dsFv)-PE38 immunotoxin A recombinant immunotoxin consisting of the single chain anti-mesothelin monoclonal antibody SS1(dsFv) linked to Pseudomonas exotoxin PE-38. The monoclonal antibody moiety of the agent binds to cells that express mesothelin, a cell surface glycoprotein which may be overexpressed in ovarian cancer, mesotheliomas, and some squamous cell carcinomas; after internalization, the exotoxin moiety inactivates eukaryotic translation elongation factor 2, thereby disrupting tumor cell protein synthesis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
