On-target, off-tumour toxicity is a major concern in immunotherapy. Here, aided by computer docking analysis, the authors introduce a single oxygen atom into the TLR7/8 agonist R848, generating a radiotherapy-activatable prodrug agonist that in mice helps mitigate systemic toxicity while triggering effective anti-tumor immunity responses upon radiation.
