Naptumomab estafenatox (ABR-217620) is a drug being developed for the treatment of various types of cancer like non-small cell lung carcinoma[1] and renal cell carcinoma.[2]
Mechanism of action
Chemically, it is a fusion protein consisting of the antigen-binding fragment (Fab) of a monoclonal antibody with the superantigen staphylococcal enterotoxin A (SEA/E-120, "estafenatox").[3] The Fab binds to 5T4, an antigen expressed by various tumor cells, and the superantigen induces an immune response by activating T lymphocytes.
