Improved cell-targeting binding molecule

Abstract

The invention relates to a therapeutic combination, comprising a first proteinaceous molecule comprising a first binding site for binding to a first epitope of a first cell-surface molecule, the first proteinaceous molecule provided with at least one saponin covalently bound to an amino-acid residue of said first proteinaceous molecule, and comprising a second pharmaceutical composition comprising a second proteinaceous molecule different from the first proteinaceous molecule, the second proteinaceous molecule comprising a second binding site for binding to a second epitope of a second cell-surface molecule different from the first cell-surface molecule, and comprising an effector moiety, wherein the second epitope is different from the first epitope. An aspect of the invention is a composition comprising the first proteinaceous molecule and the second proteinaceous molecule of the invention. The invention also relates to an antibody-drug conjugate comprising the first proteinaceous molecule of the invention and an effector moiety. An aspect of the invention relates to a pharmaceutical composition comprising the composition or the antibody-drug conjugate of the invention, and optionally further comprising a pharmaceutically acceptable excipient. The invention also relates to the therapeutic combination or the composition or the antibody-drug conjugate or the pharmaceutical composition of the invention, for use as a medicament. The invention also relates to the therapeutic combination of the invention for use in the treatment or prophylaxis of a cancer.
