  • Publication number: 20190262467
    Abstract: The present invention is based on the surprising finding that the linker employed in a bioconjugate, such as an anti-body-drug conjugate, is not therapeutically inert but has an effect on the therapeutic index of the bioconjugate. The present invention thus concerns a method for increasing the therapeutic index of a bioconjugate and the bioconjugates for use in treatment, in particular cancer. The bioconjugates according to the invention have a sulfamide linker comprising a group according to formula (1).
