Outline of Final Research Achievements |
In this study, we aimed to search for biomarkers that would serve as companion diagnostics for the HPV16E7-expressing lactobacillus vaccine that is being developed as a cancer immunotherapy targeting HPV16 onco-protein E7. We thought that HPV16E7 expression level in the exfoliated cells collected from high-grade cervical intraepithelial neoplasia CIN2-3 could be the most promising marker. We here established an assay system to measure HPV16E7 expression in the lesion using RT-PCR. We will examine the usefulness of HPV16E7 expression as a companion diagnosis in ongoing investigator-initiated clinical trials.

Academic Significance and Societal Importance of the Research Achievements |
高度子宮頸部上皮内腫瘍CIN2-3に対する薬物療法は未だに未開発のアンメットニーズである。HPVには抗ウイルス薬は存在せず、現在、治療薬開発で最も有力な候補は免疫療法である。世界的に開発が進んでいる。免疫療法では有効例と無効例の差が大きい特徴があり、有効例選択の診断ツールの必要性が高く、その候補であるコンパニオン診断の測定系を開発したことは有意義である。
