    PARP1 hyperactivation by the decoy oligodeoxynucleotide OX425 mediates DNA repair abrogation and unleashes the anti-tumor immune response (AACR 2023)
    Our results provide preclinical rationale for using OX425 to trigger DNA damage exhaustion and STING activation in cancer cells and initiate inflammatory responses that can be actioned by immune checkpoint inhibitors in patients bearing HRD or HRP tumors

    PARP1 trapping and hyperactivation by the decoy agonist OX425 induces DNA repair abrogation and a robust anti-tumor immune response (ESMO-TAT 2023)
    Importantly, OX425 treatment significantly delayed acquired resistance to olaparib in BRCA1 mutated MDA-MB-436 cell-derived xenografts. Conclusions Our results provide a safety profile and preclinical rationale for using OX425 in patients bearing HRD tumors, to trigger DNA damage exhaustion and initiate inflammatory responses in the tumor microenvironment.
