Multimodality analysis confers a prognostic benefit of a T-cell infiltrated tumor microenvironment and peripheral immune status in patients with melanoma. (PubMed, J Immunother Cancer)
An inflamed pretreatment tumor microenvironment, possibly induced by prior anti-PD-1 therapy and a proficient peripheral blood pretreatment innate immune response (antiviral/interferon signaling) to lerapolturev was associated with long term PFS after intratumoral lerapolturev in a small cohort of patients. These findings imply a link between intratumoral T cell inflammation and peripheral immune function.

CXCR3 signaling engages glioma infiltrating T cells and is required for the antitumor efficacy of innate stimulating immunotherapy (SNO 2022)
The capacity of relevant innate stimulating immunotherapies to induce CXCR3 ligands in human glioma tissue was assessed using an ex vivo glioma slice culture assay, and the contribution of CXCR3 signaling to polio virotherapy (PVSRIPO) and STING agonist therapy was tested in murine models... This work indicates that CXCR3 signaling, a key contributor to cancer immune surveillance, is disrupted in human gliomas relative to other solid tumor types. Intratumor virotherapy and STING agonists hold potential to rectify diminished CXCR3 ligand expression in gliomas.

Polio virotherapy of murine brain tumors induces microglia proliferation and inflammation that is potentiated by immune checkpoint blockade (SNO 2021)
Immunotherapy with polio:rhinovirus recombinant (PVSRIPO) has shown evidence of efficacy in a phase I clinical trial for recurrent GBM, resulting in durable radiographic responses and 21% long-term survival at 36 months...Thus, buttressing type-I IFN directed antitumor CD8+T cell immunity, e.g. with blockade of the PD1:PD-L1 immune checkpoint, might contribute to tumor remission. Indeed, combination therapy with αPD-L1 antibody in the CT2A model showed longer median survival and higher long-term remission rate compared to monotherapy alone; CD8 T cell depletion can completely abrogate this efficacy with this therapy combination, confirming the role of anti-tumor immunity in this approach.

Intratumor childhood vaccine-specific CD4+ T cell recall helps antitumor CD8 T cells (SITC 2021)
Conclusions Childhood vaccine-specific CD4+ T cells hold cancer immunotherapy potential. In the context of PVSRIPO therapy, antitumor and inflammatory effects of polio vaccine-specific CD4+ T cell recall supersedes inhibitory effects of attenuated intratumor viral replication, and represents a novel mechanism of action.

Phase I trial of intratumoral PVSRIPO in patients with unresectable, treatment-refractory melanoma. (PubMed, J Immunother Cancer)
Intratumoral PVSRIPO was well tolerated. Despite the limited number of PVSRIPO treatments relative to the overall lesion burden (67% patients>5 lesions), intratumoral PVSRIPO showed promising antitumor activity, with pCR in injected as well as non-injected lesions in select patients.

Persistent STAG2 mutation despite multimodal therapy in recurrent pediatric glioblastoma. (PubMed, NPJ Genom Med)
This report describes the genetic findings, obtained from whole-exome sequencing of a pediatric patient with glioblastoma who underwent multiple surgical resections and treatment with standard chemoradiation, as well as a novel recombinant poliovirus vaccine therapy...As such, this case represents a novel report following the clinical and genetic progression of a STAG2 mutated glioblastoma, including treatment with a novel and emerging immunotherapy. Although STAG2 deficiency comprises only a small subset of gliomas, this case adds clinical evidence to existing preclinical data supporting a role for STAG2 mutations in gliomagenesis and resistance to standard therapies.
