Atr inhibition as an attractive therapeutic resource against cancer

Abstract

In this issue of Cancer Discovery, Yap and colleagues demonstrate in a phase I trial enrolling 22 patients diagnosed with advanced solid tumors that BAY 1895344, a new potent and specific ATR inhibitor, is safe and able to induce durable responses in ATM-deficient tumors. This compelling clinical activity paves the way for innovative combination regimens that rely on exploitation of DNA damage response defects in cancer.
