  • Publication number: 20260034220
    Abstract: The invention provides immunoconjugates of Formula I comprising an anti-CEA antibody linked by conjugation to one or more 8-Het-2-aminobenzazepine derivatives. The invention also provides 8-Het-2-aminobenzazepine derivative intermediate compositions comprising a reactive functional group. Such intermediate compositions are suitable substrates for formation of the immunoconjugates through a linker or linking moiety. The invention further provides methods of treating cancer with the immunoconjugates.
