Outline of Research at the Start

これまでの前臨床・臨床知見をより発展させながら、1)大規模併用スクリーニングを行い、TAK-931がどのような化学療法剤と併用効果を示すかを明らかとする、2)リン酸化プロテミクス解析を行い、上記併用効果の細胞内シグナルの動きを明らかとする、3)上記細胞内シグナル変動の生物学的意義を、細胞・分子生物学的アプローチやsiRNAスクリーニングを用いて明らかとする、4)臨床腫瘍株(PDX)モデルを用いたin vivo併用薬効試験を行い、上記併用効果の臨床応用への可能性を示すことを目的とし、共同研究者と協力しながら研究を進めて予定である。

Outline of Final Research Achievements

We developed a highly specific CDC7 inhibitor, TAK-931, as a clinical cancer therapeutic agent. This study aimed to identify the potential combination partners of TAK-931 for guiding its clinical development strategies. Unbiased high-throughput chemical screening revealed that the highest synergistic antiproliferative effects observed were the combinations of DNA-damaging agents with TAK-931. Functional phosphoproteomic analysis demonstrated that TAK-931 suppressed homologous recombination repair activity, delayed recovery from double-strand breaks, and led to accumulation of DNA damages in the combination. Whole-genome small interfering RNA library screening identified sensitivity-modulating molecules, which propose the experimentally predicted target cancer types for the combination, including pancreatic, esophageal, ovarian, and breast cancers. The efficacy of combination therapy in
these cancer types was preclinically confirmed in the corresponding primary-derived xenograft models.

Academic Significance and Societal Importance of the Research Achievements

併用療法研究によりTAK-931と相乗効果を示す化学療法剤が同定されれば、併用パートナーの対象癌種を主軸においた「対象疾患の絞り込み」が可能となりTAK-931の開発戦略を決定する上で非常に重要な情報となる。「併用効果=合成致死」ととらえることができるため、併用パートナーの作用機序情報を活用しながら、ケミカルバイオロジーと薬理学アプローチからCDC7キナーゼの新規メカニズム解明にもつながる。TAK-931の新規併用療法の立案という臨床的意義を示すと同時にCDC7キナーゼの新規メカニズム解明といった癌の基礎研究に対しても貢献していきたい。
