AZD6738 is an orally active, and selective ATR kinase inhibitor with IC50 of 1 nM. Phase 1/2.In four Kras mutant cell lines: H23, H460, A549, and H358, AZD6738 inhibits ATR kinase activity and impairs cell viability. In ATM-deficient H23 cells, AZD6738 strongly synergizes with cisplatin to induce rapid cell death. In p53 or ATM defective cells, AZD6738 treatment results in replication fork stalls and accumulation of unrepaired DNA damage, resulting in cell death by mitotic catastrophe.In nude mice bearing H460 and H23 tumors, AZD6738 (50 mg/kg, p.o.) results in tumor growth inhibition (TGI), and the the combination with cisplatin causes rapid regression of ATM-deficient H23 tumors. In nude mice bearing LoVo xenografts, a combination of AZD6738 (50 mg/kg) + IR (2 Gy) avoids toxicity while still maintaining efficacy.
