Anti-mesothelin antibodies and uses thereof

Abstract

The present disclosure provides isolated nanobodies based on camelid VHH domains that specifically bind to mesothelin with high affinity. Also disclosed are conjugate constructs comprising the isolated nanobodies derivatized to allow conjugation to or that are conjugated to accessory moieties, such as biologically active moieties (e.g., a cytotoxin, a non-cytotoxic drug, a radioactive agent, a protein, or an enzyme) or detectable markers (e.g., a fluorescent label or biotin). Nucleic acid molecules encoding the nanobodies and conjugate constructs, expression vectors, host cells and methods for expressing the nanobodies and conjugate constructs are also provided. Pharmaceutical compositions comprising the nanobodies and conjugate-constructs as described herein are also provided. The present invention is also directed to methods for detecting mesothelin, as well as methods for diagnosis, treating, preventing and ameliorating mesothelin-associated diseases and conditions (e.g., a cancer characterized by altered expression of mesothelin), or a symptom thereof.
