TRISPECIFIC BINDING MOLECULES, WHICH SPECIFICALLY BIND ANTIGENS OF A VARIETY OF MALIGNANT TUMORS, AND METHODS OF USING THEM Russian patent published in 2020 - IPC A61K39/395 C07K16/00 

Abstract RU 2718692 C2

FIELD: medicine; pharmaceuticals.

SUBSTANCE: invention relates to trispecific binding molecules which are multi-stranded polypeptide molecules, which have three binding domains and are thus capable of mediating coordinated binding with three epitopes.

EFFECT: trispecific binding molecule is preferably characterized by that it has binding domains which enable it to immunospecifically bind to: (1) an epitope of a first antigen of a malignant tumor, (2) an epitope of a second antigen of a malignant tumor, and (3) an epitope of the molecule, which is expressed on the surface of the effector cells of the immune system, and is thus able to localize the effector cell of the immune system with the cell, which expresses a malignant tumor antigen, so as to facilitate the destruction of such a malignant tumor cell.
