  • Anti-MUC1 antibody-drug conjugate
    Patent number: 12479926
    Abstract: The present disclosure relates to antibody drug conjugates directed against the cancer antigen MUC1. In particular, an antibody with improved antigen binding was obtained by deleting a glycosylation site in the CDR-H2 of a known anti-MUC1 antibody. The conjugates consist of exatecan derivatives coupled to the anti MUC1 antibodies.
