These collective findings differentiate VAX014 from OVs by elucidating the ability of this agent to elicit antitumor activity in STING- and/or RIG-I-positive solid tumors and provide evidence that STING/RIG-I agonism is part of VAX014's mechanism of action. Taken together, this work supports the ongoing clinical investigation of VAX014 treatment as an alternative to OV therapy in patients with solid tumors.

STING (stimulator of interferon response cGAMP interactor 1)
Conclusions VAX014 activates both the murine STING and RIG-I pathways and the presence of tumor-intrinsic STING and/or RIG-I leads to optimal antitumor activity of VAX014 following i. t. administration. This unique mechanism pairs STING and RIG-I agonism and subsequent Type I IFN production with oncolysis-mediated availability of tumor antigens, which together, may lead to better antitumor T cell priming.

STING (stimulator of interferon response cGAMP interactor 1)
Intratumoral administration of VAX014 stimulates local immune activation and robust systemic antitumor lymphocytic responses. Combination with systemic ICB deepens systemic antitumor responses to mediate clearance of injected and distal non-injected tumors.
