  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).

  本发明基于一个令人惊讶的发现，即生物结合物中使用的连接剂，如抗体药物结合物，不是治疗惰性的，而是对生物结合物的治疗指数产生影响。因此，本发明涉及一种增加生物结合物的治疗指数的方法，以及用于治疗，特别是癌症的生物结合物。根据本发明的生物结合物具有包含符合式（1）的基团的磺酰胺连接剂。
