KRAS-LKB1 (KL) mutant lung cancers silence STING owing to intrinsic mitochondrial dysfunction, resulting in T cell exclusion and resistance to programmed cell death (ligand) 1 (PD-[L]1) blockade. Here we discover that KL cells also minimize intracellular accumulation of 2′3′-cyclic GMP-AMP (2′3′-cGAMP) to further avoid downstream STING and STAT1 activation. An unbiased screen to co-opt this vulnerability reveals that transient MPS1 inhibition (MPS1i) potently re-engages this pathway in KL cells via micronuclei generation. This effect is markedly amplified by epigenetic de-repression of STING and only requires pulse MPS1i treatment, creating a therapeutic window compared with non-dividing cells. A single course of decitabine treatment followed by pulse MPS1i therapy restores T cell infiltration in vivo, enhances anti-PD-1 efficacy, and results in a durable response without evidence of significant toxicity. KRAS-LKB1 (KL) lung cancers epigenetically silence STING and resist PD-1 blockade. Here, Kitajima et al. discover that MPS1 inhibition strongly reactivates KL cGAS-STING signaling following epigenetic STING de-repression. Microfluidic and animal models demonstrate potent T/NK cell recruitment by this combination, reversing anti-PD-1 resistance and revealing a strategy translatable to the clinic.
