FIELD: biotechnology.
SUBSTANCE: disclosed are antibody molecules which bind mesothelin (MSLN) and CD137, as well as a pharmaceutical composition comprising them. Said antibody molecules contain a CDR-based binding site for MSLN and an antigen-binding site for CD137 located in the constant domain of the antibody molecule. Invention also relates to nucleic acids coding antibodies, expression vectors and host cells containing said nucleic acids, a method of producing the antibody.
EFFECT: invention provides higher binding affinity of antibody molecule with immobilized MSLN than with MSLN in solution, and can find application in cancer treatment.
