Preferred Label : Anti-PTK7 Antibody-drug Conjugate SKB518;
NCIt synonyms : ADC SKB518; Anti-PTK7 ADC SKB518;
NCIt definition : An antibody-drug conjugate (ADC) composed of an antibody directed against human inactive
tyrosine-protein kinase 7 (protein tyrosine kinase 7; PTK7) conjugated to a DNA topoisomerase
I inhibitor, with potential antineoplastic activity. Upon administration of anti-PTK7
ADC SKB518, the anti-PTK7 antibody targets and binds to PTK7 expressed on tumor cells.
Upon binding and internalization, the topoisomerase I inhibitor inhibits DNA topoisomerase
I activity, thereby inhibiting DNA replication and resulting in DNA damage, cell cycle
arrest and apoptosis in tumor cells overexpressing PTK7. In addition, this may cause
a bystander effect, thereby further killing PTK7-expressing tumor cells. PTK7, a tumor-associated
antigen (TAA), is overexpressed on a variety of cancer cells with limited expression
in normal tissues. It is an integral player in cancer cell stemness and tumor progression.;
