    The novel ATR inhibitor M1774 induces replication protein overexpression and broad synergy with DNA-targeted anticancer drugs. (PubMed, Mol Cancer Ther)
    As single agent, M1774 suppressed cancer cell viability at nanomolar concentrations, showing greater activity than ceralasertib and berzosertib, but less potency than gartisertib and elimusertib in the small-cell lung cancer H146, H82, and DMS114 cell lines. Low dose of M1774 was found highly synergistic with a broad spectrum of clinical DDAs including TOP1 inhibitors (SN-38/irinotecan, topotecan, exatecan, and exatecan), the TOP2 inhibitor etoposide, cisplatin, the RNA polymerase II inhibitor lurbinectedin, and the PARP inhibitor talazoparib in various models including cancer cell lines, patient-derived organoids, and mouse xenograft models. Furthermore, we demonstrate that M1774 reverses chemoresistance to anticancer DDAs in cancer cells lacking SLFN11 expression, suggesting that SLFN11 can be utilized for patient selection in upcoming clinical trials.

    Combination of M1774 and niraparib can overcome ATR and PARP inhibitor resistance in BRCA1 mutated ovarian cancer models (AACR 2023)
    Collectively, these results indicate that the combination of M1774 and niraparib can overcome PARP inhibitor resistance and ATR inhibitor resistance in BRCA1-mutant ovarian cancer PDX models and demonstrate the utility of organoid cultures for discerning mechanisms of resistance and strategies to restore drug sensitivity. Combined M1774-mediated ATR inhibition and PARP inhibition may be a promising therapeutic strategy for the treatment of ovarian cancer.
