Outline of Final Research Achievements

We prepared mouse a pancreatic cancer cell line derived from genetically engineered mice. The pancreatic cancer cell line had an ability to form orthotopic tumors with an abundant stroma. Therefore, we adopted this mouse model to evaluate the drug efficacy. Also, we prepared anti-tissue factor (TF) antibody-drug conjugate (ADC) using two types of linker and investigated the feasibility of them. Anti-TF ADC showed greater antitumor effect and more extended survival time than control ADC in the orthotopic tumor model. Treatment with anti-TF ADC did not affect mouse body weight changes in these experiments. Furthermore, immunofluorescence staining indicated anti-TF ADC targeted not only to TF-positive tumor cells, but also to TF-positive tumor vascular endothelial cells.

Academic Significance and Societal Importance of the Research Achievements

TFを標的としたADCの一つ、tisotumab vedotinは既に臨床試験が進んでいる。TFは本来、血液凝固の開始因子として機能しているため、正常組織にも少なからず発現が見られる。そのため、宿主由来TF抗原に交差する抗体を用いた検討は必須であるが、これまでそのような報告は無かった。本研究では、腫瘍間質を豊富に形成するマウス膵がん細胞株を樹立すると共に、抗マウス抗体を用いて作製したADCの抗腫瘍活性を評価することで、より臨床腫瘍を模倣した抗TF-ADCの評価系を構築した。そのため、本研究により得られた知見は今後の抗TF-ADCを開発、さらには改良する上で重要であると考える。
