    PG545 sensitizes ovarian cancer cells to PARP inhibitors through modulation of RAD51-DEK interaction. (PubMed, Oncogene)
    Synergistic antitumor activity of the PG545/rucaparib combination was likewise observed in an immunocompetent syngeneic ID8F3 OC model. Collectively, these results suggest that targeting DEK-HSPG interactions in the TME through the use of PG545 may be a novel method of inhibiting DNA repair and sensitizing cells to PARPis.

    Phase Ib open-label, multicenter study of pixatimod, an activator of TLR9, in combination with nivolumab in subjects with microsatellite-stable metastatic colorectal cancer, metastatic pancreatic ductal adenocarcinoma and other solid tumors. (PubMed, J Immunother Cancer)
    Pixatimod is well tolerated at 25 mg in combination with nivolumab. The efficacy signal and pharmacodynamic changes in MSS mCRC warrants further investigation.

    [VIRTUAL] Synergistic cytotoxic effect of sulfated glycolipid PG545 in combination with ATR inhibition in ovarian cancer cells (AACR 2021)
    Proliferation and clonogenic assay showed that combination of PG545 with ATR shRNA or ATR inhibitor (ATRi; VE-822) synergistically decreased cell survival compared with single-agent treatments in two OC cell lines, OVCAR5 and OVCAR8 cells. Moreover, ATRi diminished the cell cycle effects of PG545 and markedly enhanced PG545-induced apoptosis in OC cell lines. Taken together, our results indicate that the combination of PG545 with ATR inhibition may be promising options to be considered in future clinical trials of OC.

    Sulfated glycolipid PG545 induces endoplasmic reticulum stress and augments autophagic flux by enhancing anticancer chemotherapy efficacy in endometrial cancer. (PubMed, Biochem Pharmacol)
    PG545 exhibited strong synergy as assessed by the Chou-Talalay-Method in vitro when combined with cisplatin, or paclitaxel in both type I (Hec1B) and type II (ARK2) EC cell lines. Collectively these data indicate that PG545 exhibits strong synergistic effects with chemotherapeutics in vitro and showed promising antitumor activity in vivo. Our preclinical data indicates that in future studies PG545 can be a useful adjunct to chemotherapy in endometrial cancer.
