The present invention relates to antibody-drug conjugates comprising (i) an antibody or antigen-binding fragment thereof, (ii) a polymer comprising a particular repeat unit comprising an amino acid derivative, which is covalently bound to one or more biologically active moieties, such as small molecule drugs, optionally via a linker, and (iii) a polymer-antibody linker moiety which is covalently bound to both the polymer and the antibody or antigen-binding fragment thereof. Additionally, the present invention relates to pharmaceutical compositions comprising the antibody-drug conjugates and to use of the antibody-drug conjugates in medicine.
本发明涉及抗体-药物偶联物,包括(i)抗体或其抗原结合片段,(ii)聚合物,其中包括一个特定重复单元,该单元包括氨基酸衍生物,与一个或多个生物活性基团如小分子药物共价结合,可选地通过连接剂连接,以及(iii)聚合物-抗体连接基团,它们与聚合物和抗体或其抗原结合片段均共价结合。此外,本发明涉及包括抗体-药物偶联物的药物组合物以及在医学上使用抗体-药物偶联物。
