1. Enhancing anti-EGFRvIII CAR T cell therapy against glioblastoma with a paracrine SIRPγ-derived CD47 blocker

Abstract: Abstract A significant challenge for chimeric antigen receptor (CAR) T cell therapy against glioblastoma (GBM) is its immunosuppressive microenvironment, which is densely populated by protumoral glioma-associated microglia and macrophages (GAMs). Myeloid immune checkpoint therapy targeting the CD47-signal regulatory protein alpha (SIRPα) axis induces GAM phagocytic function, but CD47 blockade monotherapy is associated with toxicity and low bioavailability in solid tumors. In this work, we engineer a CAR T cell against epidermal growth factor receptor variant III (EGFRvIII), constitutively secreting a signal regulatory protein gamma-related protein (SGRP) with high affinity to CD47. Anti-EGFRvIII-SGRP CAR T cells eradicate orthotopic EGFRvIII-mosaic GBM in vivo, promoting GAM-mediated tumor cell phagocytosis. In a subcutaneous CD19+ lymphoma mouse model, anti-CD19-SGRP CAR T cell therapy is superior to conventional anti-CD19 CAR T. Thus, combination of CAR and SGRP eliminates bystander tumor cells in a manner that could overcome main mechanisms of CAR T cell therapy resistance, including immune suppression and antigen escape.

Abstract: Glioblastoma (GBM) harbors a highly immunosuppressive tumor microenvironment (TME) which influences glioma growth. Major efforts have been undertaken to describe the TME on a single-cell level. However, human data on regional differences within the TME remain scarce. Here, we performed high-depth single-cell RNA sequencing (scRNAseq) on paired biopsies from the tumor center, peripheral infiltration zone and blood of five primary GBM patients. Through analysis of >45,000 cells, we revealed a regionally distinct transcription profile of microglia (MG) and monocyte-derived macrophages (MdMs) and an impaired activation signature in the tumor-peripheral cytotoxic-cell compartment. Comparing tumor-infiltrating CD8+ T cells with circulating cells identified CX3CR1high and CX3CR1int CD8+ T cells with effector and memory phenotype, respectively, enriched in blood but absent in the TME. Tumor CD8+ T cells displayed a tissue-resident memory phenotype with dysfunctional features. Our analysis provides a regionally resolved mapping of transcriptional states in GBM-associated leukocytes, serving as an additional asset in the effort towards novel therapeutic strategies to combat this fatal disease.

Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its associated symptoms, named coronavirus disease 2019 (COVID-19), have rapidly spread worldwide, resulting in the declaration of a pandemic. When several countries began enacting quarantine and lockdown policies, the pandemic as it is now known truly began. While most patients have minimal symptoms, approximately 20% of verified subjects are suffering from serious medical consequences. Co-existing diseases, such as cardiovascular disease, cancer, diabetes, and others, have been shown to make patients more vulnerable to severe outcomes from COVID-19 by modulating host–viral interactions and immune responses, causing severe infection and mortality. In this review, we outline the putative signaling pathways at the interface of COVID-19 and several diseases, emphasizing the clinical and molecular implications of concurring diseases in COVID-19 clinical outcomes. As evidence is limited on co-existing diseases and COVID-19, most findings are preliminary, and further research is required for optimal management of patients with comorbidities.

Subjects: glioblastoma, immunotherapy, microglia modulation, glioma-associated microglia, glioma- associated macrophages, immune tumor microenvironment, Immunologic diseases. Allergy, RC581-607
Abstract: Tumor-associated microglia (MG) and macrophages (MΦ) are important components of the glioblastoma (GBM) immune tumor microenvironment (iTME). From the recent advances in understanding how MG and GBM cells evolve and interact during tumorigenesis, we emphasize the cooperation of MG with other immune cell types of the GBM-iTME, mainly MΦ and T cells. We provide a comprehensive overview of current immunotherapeutic clinical trials and approaches for the treatment of GBM, which in general, underestimate the counteracting contribution of immunosuppressive MG as a main factor for treatment failure. Furthermore, we summarize new developments and strategies in MG reprogramming/re-education in the GBM context, with a focus on ways to boost MG-mediated tumor cell phagocytosis and associated experimental models and methods. This ultimately converges in our proposal of novel combinatorial regimens that locally modulate MG as a central paradigm, and therefore may lead to additional, long-lasting, and effective tumoricidal responses.

Subjects: Neoplasms. Tumors. Oncology. Including cancer and carcinogens, RC254-282
Abstract: Intratumoral delivery of viruses and virus-associated molecular patterns can achieve antitumor effects that are largely mediated by the elicitation or potentiation of immune responses against the malignancy. Attenuated vaccines are approved and marketed as good manufactiring practice (GMP)-manufactured agents whose administration might be able to induce such effects. Recent reports in mouse transplantable tumor models indicate that the rotavirus, influenza and yellow fever vaccines can be especially suitable to elicit powerful antitumor immunity against cancer following intratumoral administration. These results highlight that intratumoral anti-infectious vaccines can turn cold tumors into hot, and underscore the key role played by virus-induced type I interferon pathways to overcome resistance to immune checkpoint-targeted antibodies.

Subjects: cold tumors, T cells, tumor antigen, presentation, priming, trafficking, Immunologic diseases. Allergy, RC581-607
Abstract: Therapeutic monoclonal antibodies targeting immune checkpoints (ICPs) have changed the treatment landscape of many tumors. However, response rate remains relatively low in most cases. A major factor involved in initial resistance to ICP inhibitors is the lack or paucity of tumor T cell infiltration, characterizing the so-called “cold tumors.” In this review, we describe the main mechanisms involved in the absence of T cell infiltration, including lack of tumor antigens, defect in antigen presentation, absence of T cell activation and deficit of homing into the tumor bed. We discuss then the different therapeutic approaches that could turn cold into hot tumors. In this way, specific therapies are proposed according to their mechanism of action. In addition, ‘‘supra-physiological’’ therapies, such as T cell recruiting bispecific antibodies and Chimeric Antigen Receptor (CAR) T cells, may be active regardless of the mechanism involved, especially in MHC class I negative tumors. The determination of the main factors implicated in the lack of preexisting tumor T cell infiltration is crucial for the development of adapted algorithms of treatments for cold tumors.

Abstract: The coronavirus disease 2019 (COVID-19) pandemic has created unprecedented challenges worldwide. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19 and has a complex interaction with the immune system, including growing evidence of sex-specific differences in the immune response. Sex-disaggregated analyses of epidemiological data indicate that males experience more severe symptoms and suffer higher mortality from COVID-19 than females. Many behavioural risk factors and biological factors may contribute to the different immune response. This review examines the immune response to SARS-CoV-2 infection in the context of sex, with emphasis on potential biological mechanisms explaining differences in clinical outcomes. Understanding sex differences in the pathophysiology of SARS-CoV-2 infection will help promote the development of specific strategies to manage the disease.

8. Multidimensional analysis of matched primary and recurrent glioblastoma identifies Fcγ receptors upregulation on microglia as a contributor of tumor recurrence

Abstract: Background: Glioblastoma (GBM) is a lethal brain tumor without effective treatment options. The aim of this study was to characterize longitudinal tumor immune microenvironment (iTME) changes in order to find potential actionable targets to prevent GBM-induced immune evasion mechanisms.Methods: This study included 15 patient-matched treatment-naïve WHO grade 4 primary (pGBM) and recurrent (rGBM) tumors. RNA and proteins extracted from fresh frozen tumor samples from matched pGBM and rGBM were profiled via transcriptomics and proteomics, respectively. A tissue microarray containing paired formalin-fixed paraffin-embedded tumor samples was processed for spatial transcriptomics analysis.Results: Differentially expressed genes and proteins between pGBM and rGBM were involved in pathways responsible for synapse development and myelination which have been shown to play a role in GBM recurrence. By categorizing patients into short and long time-to-relapse (STTR vs LTTR), we identified genes positively or negatively associated with TTR. Expression of Fcγ receptors and complement system genes such asFCGR1A(CD64),FCGR3AandC3in rGBM samples were negatively correlated with TTR, whereas expression ofDNMT1/3A, andSMARCA4, involved in DNA methylation, were positively correlated with TTR. Spatial transcriptomic analysis of the tumor cell compartment showed enrichment of oligodendrocytes in rGBM, whereas the myeloid cell compartment switched from quiescent to activated microglia, was enriched in B and T cells, specifically in rGBM with STTR.Conclusions:Our results uncover a role for CD64-expressing activated microglia in GBM recurrence and suggest that interfering with these cells may represent a therapeutic option for hindering GBM relapse.Key points:Transcriptomic and proteomic differences exist between patient-paired primary and recurrent GBM tumorsHigh expression of Fcy receptors genes on activated microglia at tumor recurrence is associated with shorter time to relapse.Importance of this study:In glioblastoma (GBM), the tumor recurs in almost all cases after standard treatment such as surgery and chemo-radiotherapy. In this study, we longitudinally evaluated the immune- and neoplastic compartments using transcriptomic, proteomic, and spatial transcriptomics in patient-matched treatment-naive and recurrent tumor samples. By correlating gene expression with time-to-relapse, we identified a geneset associated with treatment resistance and faster tumor recurrence. Moreover, this study highlighted the plasticity of the myeloid compartment during disease progression and an unfavorable role of activated microglia in tumor recurrence.

9. The Siglec-sialic acid-axis is a target for innate immunotherapy of glioblastoma

Abstract: Glioblastoma (GBM) is the most aggressive form of primary brain tumor, for which effective therapies are urgently needed. Cancer cells are capable of evading clearance by phagocytes such as microglia and monocyte-derived cells through engaging tolerogenic programs. Here, we found that high level of Siglec-9 expression correlates with reduced survival in GBM patients. Using conditional knockouts of Siglec-E, the murine functional homologue of Siglec-9, together with single-cell RNA sequencing, we demonstrated significant pro-phagocytosis effects in microglia and monocyte-derived cells in the absence of Siglec-E. Loss of Siglec-E on monocyte-derived cells enhances antigen cross-presentation and production of pro-inflammatory cytokines, resulting in more efficient T cell priming. This bridging of innate and adaptive responses delays tumor growth and results in prolonged survival. Further, we showed synergistic activity of Siglec-E blockade in combinatorial immunotherapies and demonstrate its translational potential against GBM.

10. Immunotherapy of glioblastoma explants induces interferon-γ responses and spatial immune cell rearrangements in tumor center, but not periphery

Schürch, and Gregor Hutter
Abstract: Recent therapeutic strategies for glioblastoma (GBM) aim at targeting immune tumor microenvironment (iTME) components to induce antitumoral immunity. A patient-tailored, ex vivo drug testing and response analysis platform for GBM would facilitate personalized therapy planning, provide insights into treatment-induced immune mechanisms in the iTME, and enable the discovery of biomarkers of therapy response and resistance.We cultured 47 GBM explants from tumor center and periphery from 7 patients in perfusion bioreactors to assess iTME responses to immunotherapy. Explants were exposed to antibodies blocking the immune checkpoints CD47, PD-1 or or their combination, and were analyzed by highly multiplexed microscopy (CODEX, co-detection by indexing) using an immune-focused 55-marker panel. Culture media were examined for changes of soluble factors including cytokines, chemokines and metabolites. CODEX enabled the spatially resolved identification and quantification of >850,000 single cells in explants, which were classified into 10 cell types by clustering. Explants from center and periphery differed significantly in their cell type composition, their levels of soluble factors, and their responses to immunotherapy. In a subset of explants, culture media displayed increased interferon-γ levels, which correlated with shifts in immune cell composition within specific tissue compartments, including the enrichment of CD4+ and CD8+ T cells within an adaptive immune compartment. Furthermore, significant differences in the expression levels of functional molecules in innate and adaptive immune cell types were found between explants responding or not to immunotherapy. In non-responder explants, T cells showed higher expression of PD-1, LAG-3, TIM-3 and VISTA, whereas in responders, macrophages and microglia showed higher cathepsin D levels. Our study demonstrates that ex vivo immunotherapy of GBM explants enables an active antitumoral immune response within the tumor center in a subset of patients, and provides a framework for multidimensional personalized assessment of tumor response to immunotherapy.

12. TMIC-77. SINGLE-CELL CHARACTERIZATION OF HUMAN GBM REVEALS REGIONAL DIFFERENCES IN TUMOR-INFILTRATING LEUKOCYTE ACTIVATION

Subjects: Cancer Research, Oncology, Neurology (clinical)
Abstract: Clinical trials of systemic T cell checkpoint blockade in GBM patients showed only disappointing results. This may be attributed in part to the immunosuppressive components of the GBM immune tumor microenvironment (iTME). Therefore, major efforts have been undertaken to describe the GBM iTME on a single cell level. However, human data on the composition of the iTME in different tumor regions (contrast enhancing tumor center versus peripheral infiltration zone) remain scarce. Here, we performed high-depth single-cell RNA sequencing (scRNAseq) on patient-matched biopsies from the tumor center and the peripheral infiltration zone of five primary GBM patients. Additionally, peripheral blood mononuclear cells (PBMC) of the same patients were included in the scRNAseq analysis to explore the transcriptional changes occurring during tumor infiltration of circulating immune cells. Through analysis of > 45’000 cells, we revealed a distinct regional transcriptional profile of microglia (MG) and monocyte-derived macrophages (MdM), a non-reactive/exhausted MG subcluster in the GBM iTME and an impaired interferon-response signature in the peripheral cytotoxic cell compartment. Comparing CD8+ T-cells from the tumor periphery to PBMC-derived CD8+ T-cells of the same patient revealed a CX3CR1+ CD8+ T-cell population with effector memory phenotype which is enriched in the PBMC but lacking in the tumor periphery. Peripheral CD8+ T-cells were mainly composed of tissue-resident memory CD8+ T-cells with exhausted effector functions. Our analysis provides a large-scale dissection of GBM-associated cell types complemented by patient-matched PBMCs, serving as a high dimensional reference map of the human GBM iTME.

Abstract: The immune tumor microenvironment (iTME) of glioblastoma (GBM) contains microglial, macrophage, other myeloid cell populations and as adaptive immune cells. Recent therapeutic strategies for GBM aim at targeting iTME components to induce antitumoral immunity. A patient-tailored, ex vivo drug testing and response analysis platform would facilitate personalized therapy planning, provide insights into treatment-induced immune mechanisms in the iTME, and enable the discovery of biomarkers of response and resistance. Here, we generated patient-derived, live 3D GBM bioreactors from different tumor regions to assess iTME treatment responses to microglia modulators and immune checkpoint inhibitors. Intact GBM tissue specimens from the tumor center and periphery were cultured for 7 days in the presence or absence of anti-PD1, anti-CD47 antibodies or their combination. Tissues were analyzed by CODEX highly multiplexed microscopy using an immune-centered 54-marker panel, and changes in cytokine and chemokine levels in culture supernatants were investigated. A computational pipeline for integrative therapy response assessment was implemented. Explant cultures from n=8 IDH wt GBM were subjected to this integrative personalized analysis. Tissue integrity after 3D bioreactor cultures was comparable to tissue taken directly after surgery. FFPE CODEX workflow was feasible with adequate staining quality in bioreactor cultures. 850'000 single cells were segmented and clustered. Cellular composition between tumor center and the peripheral invasion zone differed significantly in immune phenotypes, cytokine profile and response to innate, adaptive or combinatorial local immunotherapies. Multiplexed cytokine analysis revealed IFNγ response signatures in a subset of center samples, whereas the peripheral invasion zone displayed a blunted cytokine response. This cytokine signature corresponded to cellular composition shifts within specific cellular neighborhoods. CD4 and CD8 T cells were invigorated and left their vascular niche. Our study demonstrates that local immunotherapies enable an active antitumoral immune response within the tumor center, and provides a multidimensional personalized framework for immunotherapy response assessment.

Abstract: The GBM immune tumor microenvironment mainly consists of protumoral glioma-associated microglia and macrophages (GAMs). We have previously shown that blockade of CD47, a ‘don't eat me’-signal overexpressed by GBM cells, rescued GAMs' phagocytic function in mice. However, monotherapy with CD47 blockade has been ineffective in treating human solid tumors to date. Thus, we propose a combinatorial approach of local CAR T cell therapy with paracrine GAM modulation for a synergistic elimination of GBM. We generated humanized EGFRvIII CAR T-cells by lentiviral transduction of healthy donor human T-cells and engineered them to constitutively release a soluble SIRPγ-related protein (SGRP) with high affinity towards CD47. Tumor viability and CAR T-cell proliferation were assessed by timelapse imaging analysis in co-cultures with endogenous EGFRvIII-expressing BS153 cells. Tumor-induced CAR T-cell activation and degranulation were confirmed by flow cytometry. CAR T-cell secretomes were analyzed by liquid chromatography-mass spectrometry. Immunocompromised mice were orthotopically implanted with EGFRvIII+ BS153 cells and treated intratumorally with a single CAR T-cell injection. EGFRvIII and EGFRvIII-SGRP CAR T-cells killed tumor cells in a dose-dependent manner (72h-timepoint; complete cytotoxicity at effector-target ratio 1:1) compared to CD19 controls. CAR T-cells proliferated and specifically co-expressed CD25 and CD107a in the presence of tumor antigen (24h-timepoint; EGFRvIII: 59.3±3.00%, EGFRvIII-SGRP: 52.6±1.42%, CD19: 0.1±0.07%). Differential expression analysis of CAR T-cell secretomes identified SGRP from EGFRvIII-SGRP CAR T-cell supernatants (-Log10qValue/Log2fold-change= 3.84/6.15). Consistent with studies of systemic EGFRvIII CAR T-cell therapy, our data suggest that intratumoral EGFRvIII CAR T-cells were insufficient to eliminate BS153 tumors with homogeneous EGFRvIII expression in mice (Overall survival; EGFRvIII-treated: 20%, CD19-treated: 0%, n= 5 per group). Our current work focuses on the functional characterization of SGRP binding, SGRP-mediated phagocytosis, and on the development of a translational preclinical model of heterogeneous EGFRvIII expression to investigate an additive effect of CAR T-cell therapy and GAM modulation.

Abstract: Recently, ‘don’t eat me’-signals like CD47 have emerged as novel innate immune checkpoints, enabling cancer cells to evade clearance by phagocytes such as monocyte-derived macrophages (MDM) or microglia (MG). Here, we aim at defining the role of inhibitory Siglec-9 in human and its mouse homologue Siglec-E in MG-centered immunotherapy against GBM. TCGA RNA-sequencing data revealed a significant correlation between high expression of immunoinhibitory SIGLEC9 and poor survival in GBM patients (log-rank p = 0.02). Siglec-E blockade increased murine MG mediated GBM cell in vitro phagocytosis (normalized phagocytosis of 1.00 in isotype vs. 1.76 in anti-Siglec-E antibody, p < 0.001). By employing a CT-2A orthotopic GBM mouse model with MG-specific spatio-temporal deletion of Siglece (Sall1 CreERT2 x Siglece flox ), we observed high MG-proliferation upon Siglec-E knockdown (Ki-67+ MG 14.8% in Cre- vs. 34.9% in Cre+, p < 0.0001) accompanied by an enhanced microglial GBM-cell uptake (5.6% in Cre- vs. 12.3% in Cre+, p < 0.001). This beneficial response was counteracted by an accentuated influx of pro-tumorigenic MDM in the Cre+ group (CD163high CD86low MDM of total MDM 47.1% in Cre- vs. 65.3% in Cre+, p = 0.002), which prevented an efficient adaptive anti-tumor immune response and survival benefit. Currently, we are investigating the cross-talk between GBM-associated MG and MDM upon Siglec-E knockdown by scRNAseq of the tumor-infiltrating immune compartment, including TCR-clonotype tracking. By genetically targeting sialic acids, the ligand for Siglec receptors, on CT-2A cells (GNE-KO), we observed a strong innate and adaptive immune response with less exhausted tumor-infiltrating CD8+ T-cells (14.8% in WT vs. 5.9% in GNE-KO, p = 0.003), which resulted in a prolonged survival (30d in WT vs. 41d post-tumor-injection in GNE-KO, p = 0.03). These data identify the sialic-acid-Siglec-E pathway as an anti-phagocytic signal in a pre-clinical GBM model, and demonstrate its therapeutic potential in GBM immunotherapy.

TCGA RNA-sequencing data revealed a significant correlation between high expression of immunoinhibitory SIGLEC9 and poor survival in GBM patients (log-rank p = 0.02). Using a CT-2A orthotopic GBM mouse model with MG-specific spatio-temporal deletion of Siglece (Sall1CreERT2 x Sigleceflox) , we observed high MG-proliferation upon Siglece knockout (Ki-67+ MG 14.8% in Crenegvs. 34.9% in Creposp < 0.0001) accompanied by an enhanced microglial GBM-cell uptake (5.6% in Crenegvs. 12.3% in Crepos, p < 0.001). By extending the Siglece knockout to the MdC compartment (Cx3cr1CreERT2x Sigleceflox) we observed a significantly prolonged survival in the Crepospopulation (21d in Crenegvs. 27d post-tumor injection in Crepos, p = 0.018), which could be further promoted by combining Siglece knockout with CD47 blockade (11% long-term remission in Crepos+ anti-CD47). Proteomics analysis revealed increased antigen processing and presentation capabilities of SigleceKOMdCs which was confirmed by ex-vivo OT-1 cross-presentation assays. This increased T cell priming upon MdC SigleceKOwas further boosted by addition of anti-PD1 antibody to the SigleceKO+ anti-CD47 combination. Resulting in 23% of animals experiencing long-term remission in the triple treatment arm, even after tumor re-challenge. Genetic targeting of sialic acids, the ligand for Siglec receptors, on CT-2A cells (GNE-KO), resulted in increased GBM-cell phagocytosis by MG and MdCs and less exhausted tumor-infiltrating CD8+ T cells (14.8% in WT vs. 5.9% in GNE-KO, p = 0.003). In a translational approach, we are currently testing anti-Siglec-9 treatment regimens in patient GBM explants, cultured for 5 days in perfusion bioreactors.

Abstract: Recent clinical studies in glioblastoma (GBM) highlight the potential of local IL-12 therapy, but they also bring back tolerability concerns due to leakage into the periphery. This leakage might thus hamper exploiting the full potential of local IL-12 therapy. Fusion with an IgG4 Fc portion increases the tissue retention of IL-12; but could also confer export into the blood and subsequent systemic recycling through the neonatal Fc receptor (FcRn), ultimately leading to potentially toxic IL-12 serum levels. We assessed the expression of FcRn in human and murine GBM and its role in IL-12Fc tissue retention and systemic exposure upon local delivery. Human or murine IL-12Fc was injected in GBM-bearing or naïve wt or FcRn-humanized mice continuously or as bolus via convection-enhanced delivery (CED). We screened combinations of amino-acid substitutions at the (IL-12)Fc:FcRn binding interface to abolish this interaction. Brain and blood concentrations were assessed via ELISA or cytokine bead arrays. FcRn affinity was measured by SPR/ELISA and bioactivity tested on PBMCs and human GBM explant cultures. Treatment efficacy and immunological correlates were assessed in GBM bearing mice. FcRn is upregulated in human and mouse GBM and contributes to brain export and subsequent peripheral recycling of IL-12Fc in the blood. IL-12Fc with abrogated FcRn binding due to a unique set of substitutions is fully functional and appears brain compartment locked (CL IL-12) as it exhibits enhanced tissue retention and reduced serum levels upon local injection, reaching up 100x higher brain to serum concentration ratios than regular IL-12. Compared to its non-modified counterpart, murine CL IL-12 shows significantly higher treatment efficacy at negligible systemic footprint in late stage murine GBM. In patient explant cultures, human CL IL-12 leads to successful inflammatory conditioning. Compartment locked IL-12 should thus allow a wide dosing window to fully harness its therapeutic potential for local GBM therapy.

Abstract: BACKGROUND The tumor immune microenvironment (TME) of Glioblastoma consists of almost myeloid-derived macrophages and microglia called TAMs. We have shown that the disruption of CD47-Sirpα-axis induces an antitumor activity of TAMs against GBM in immune-deficient mice, through increases of phagocytosis of tumor cells by TAMs. We have aimed to study the role of microglia and its activation/depletion on GBM progression, in the syngeneic GBM model in immune-competent mice. We have studied the interplay of innate and adaptive immune response after activation and depletion of microglia and the effect on tumor progression and outcome of the mice. MATERIAL AND METHODS We used different colonies of genetically modified immunocompetent mouse strains to genetically activate/deplete microglia in the tumor context. We generated Sall1 CreERT2/fl mice and Cre-negative littermates. The application of Tamoxifen in this constellation leads to the excision of the transcription factor Sall1 and subsequent enhanced microglia activity. Conversely, we generated Sall1 CreERT2 x Csf1r fl/fl animals and the respective heterozygous and Cre-negative littermates in which Tamoxifen treatment leads to inactivation of microglia through the deletion of Csf1r. Glioblastoma tumors were induced by intracerebral injection of GL261, CT2A, or retrovirus-induced PDGF-Akt in pups and Tamoxifen treatment was started once the tumors were detected. RESULTS We observed a survival advantage in tumor-bearing mice after activation of microglia in Sall1 CreERT/fl animals compared to Cre-negative littermates. Genetic depletion of microglia in this model resulted in a shorter lifespan in microglia-depleted animals compared to Cre-negative littermates. Furthermore, the iTME in these tumors is subjected to scRNAseq analysis to identify mechanistic insights. CONCLUSION Microglia are important players in tumor development and progression of glioblastoma in mouse models. These cells may be targeted in future immunotherapeutic approaches for patients.

Abstract: International audience; Although immune checkpoint-targeted therapies are currently revolutionizing cancer care, only a minority of patients develop durable objective responses to anti-PD-1, PD-L1, and CTLA-4 therapy. Therefore, new therapeutic interventions are needed to increase the immunogenicity of tumors and overcome the resistance to these immuno-therapies. Oncolytic properties of common viruses can be exploited for the priming of antitumor immunity, and such oncolytic viruses are currently in active clinical development in combination with immune checkpoint-targeted therapies. However, the routine implementation of these therapies is limited by their manufacturing constraints, the risk of exposure of clinical staff, and the ongoing regulations on genetically modified organisms. We sought to determine whether anti-infectious disease vaccines could be used as a commercially available source of immunostimulatory agents for cancer immunotherapy. We found that rotavirus vaccines have both immunostimulatory and oncolytic properties. In vitro, they can directly kill cancer cells with features of immunogenic cell death. In vivo, intratumoral rotavirus therapy has antitumor effects that are dependent on the immune system. In several immunocompetent murine tumor models, intratumoral rotavirus overcomes resistance to and synergizes with immune checkpoint-targeted therapy. Heat-and UV-inactivated rotavirus lost their oncolytic activity but kept their synergy with immune checkpoint-targeted antibodies through the up-regulation of the double-stranded RNA receptor retinoic acid-induced gene 1 (RIG-I). Rotavirus vaccines are clinical-grade products used in pediatric and adult populations. Therefore, in situ immunization strategies with intratumoral-attenuated rotavirus could be implemented quickly in the clinic.

Abstract: BACKGROUND Recently, strategies harnessing the non-neoplastic, immune tumor microenvironment (iTME) consisting of myeloid-derived macrophages and yolk sac derived microglia (termed TAMs) as well as adaptive immune components have been employed to treat glioblastoma (GBM). To evaluate the effect of TAM-modulating therapies in combination with T-cell checkpoint inhibitor approaches, we generated 3D GBM bioreactor cultures from patient-derived samples. Here, we report patient-tailored, tumor region specific response assessment to microglia modulators and T-cell checkpoint inhibitors using multidimensional fluorescent microscopy techniques MATERIAL AND METHODS GBM tissue fragments from the tumor center and periphery were placed into perfusion bioreactors shortly after resection and cultured for up to 3 weeks. Control conditions included non-perfused cultures of the same tissue. Cultures were treated with combinations of TAM and T-cell modulating, FDA approved drugs including anti-PD1, anti-CTLA4 and anti-CD47 antibodies. Tissue was harvested for histology, RNA extraction, and supernatants were processed for multiplexed cytokine analysis. Multidimensional CODEX technology analysis using a customized TAM/microglia-centric 50 marker panel was implemented, and a map of individualized response criteria to specific immunotherapies developed. RESULTS We were able to cultivate viable GBM tissue with intact iTME. Tumor cell proliferation and invasion capacity were preserved for up to 3 weeks. Conventional immunohistochemistry confirmed the presence of TAMs and T cells. Treatment with immunomodulators resulted in a profound polarization shift of TAMs. Furthermore, cytokine analysis confirmed proinflammatory immune responses in most assessed samples. We present preliminary data of the CODEX analysis of our combinatorial immunotherapies in a series of 8 patient-specific explant samples. CONCLUSION GBM tissue could be incubated in the perfused 3D bioreactor model and kept viable for up to 21 days. The proposed model allows patient-tailored testing of immunomodulatory drugs by taking into account the patients individual iTME response.

Abstract: Immune checkpoint targeted therapies against PD-1, PD-L1 and CTLA-4 are currently revolutionizing cancer care. However, only a minority of patients generate objective tumor responses with these treatments. Therefore, new therapeutic interventions are needed to increase the immunogenicity of tumors in order to overcome the resistance to immune checkpoint blockade therapy. Pattern recognition receptors (PRR) such as toll-like receptor agonists have been shown to overcome resistance to immune checkpoint targeted therapy in pre-clinical models. Besides their intrinsic ability to stimulate PRR, the oncolytic properties of common viruses can be exploited also for the priming of anti-tumor immune responses. Several oncolytic viruses are currently in clinical development for cancer immunotherapy. However the routine implementation of these therapies is limited by the ongoing regulations on GMOs. With the aim to analyze if anti-infectious vaccines can be used as a source or PRR agonists and/or oncolytic viruses, we infected different tumors cell lines with commercially available anti-infectious vaccines. We first confirmed that commercially available vaccines do have PRR agonist properties. More interestingly, we discovered that rotavirus vaccines also have oncolytic properties. These attenuated viruses can directly kill cancer cells with features of immunogenic cell death such as upregulation of calreticulin on dying cancer cells but doesn't have cytotoxicity on healthy primary fibroblasts. Moreover, they have pro-inflammatory properties and can activate the NF-KB pathway in a toll-like receptor and IRF3 independent manner. These in vitro biological properties translate into in vivo anti-tumor activity. Intra-tumoral (IT) rotavirus therapy has anti-tumor effects which are mainly immune mediated as demonstrated by their weaken activity in NSG mice. Interestingly, in immunocompetent syngeneic murine tumor models of neuroblastoma and lymphoma, IT rotavirus therapy can overcome resistance to immune checkpoint targeted therapy and in particular synergies with anti-CTLA4. This therapeutic effect relied on specific modifications of tumor immune infiltrates and immune activation pathways. IT rotavirus vaccines was associated to an increase of myeloid infiltrating cells expressing up-regulated level of CD86 in the tumor microenvironment, and upregulation of activation markers such as OX40/CD137 on T cells. Rotavirus vaccines are clinical grade products, including for children. Therefore, in situ immunization strategies with IT attenuated rotavirus can be implemented quickly in the clinic including in pediatric cancers. IT priming of the anti-tumor immunity with oncolytic and immunostimulatory rotavirus vaccines could be a feasible strategy to overcome resistance to anti-PD-1/anti-CTLA-4 therapy in patients with cancer.* co-last authors.

Abstract: Purpose Well-documented stability data of monoclonal antibodies are generally missing. That is why we studied the physicochemical and biological stability of undiluted ipilimumab (IPI) in glass vial (5 mg/ml) over 28 d after opening, stored at 4°C and 25°C. Method A stressed study (60°C) was performed to validate our analytical methods as ‘stability indicating’. The different methods used were turbidimetry, dynamic light scattering (DLS), second-derivative ultraviolet and chromatographic methods as size-exclusion chromatography (SEC) and cation-exchange (CEX). Biological characterisation was performed by an in vitro functional binding inhibition bioassay. Results We demonstrated that ipilimumab in opened vials stored at 4°C and 25°C remained stable for at least 28 d. No physical, chemical or structural instability was found. No aggregation was observed by turbidimetry, SEC and DLS. Hydrodynamic diameters remained unchanged, as chromatographic profiles in CEX and thermal aggregation curves. Functionally, the ability of IPI to antagonise CTLA-4/B7.2 binding remained stable over 1 month at 4°C. Conclusion These results indicate that unused residues of IPI in their original vials can be safely kept up to 28 d, following good manufacturing procedures, allowing re-use for another patient or in case of cold-chain rupture.

Abstract: The immunosurveillance mechanisms governing high-risk neuroblastoma (HR-NB), a major pediatric malignancy, have been elusive. We identify a potential role for natural killer (NK) cells, in particular the interaction between the NK receptor NKp30 and its ligand, B7-H6, in the metastatic progression and survival of HR-NB after myeloablative multimodal chemotherapy and stem cell transplantation. NB cells expressing the NKp30 ligand B7-H6 stimulated NK cells in an NKp30-dependent manner. Serum concentration of soluble B7-H6 correlated with the down-regulation of NKp30, bone marrow metastases, and chemoresistance, and soluble B7-H6 contained in the serum of HR-NB patients inhibited NK cell functions in vitro. The expression of distinct NKp30 isoforms affecting the polarization of NK cell functions correlated with 10-year event-free survival in three independent cohorts of HR-NB in remission from metastases after induction chemotherapy (n = 196, P0.001), adding prognostic value to known risk factors such as N-Myc amplification and age18 months. We conclude that the interaction between NKp30 and B7-H6 may contribute to the fate of NB patients and that both the expression of NKp30 isoforms on circulating NK cells and the concentration of soluble B7-H6 in the serum may be clinically useful as biomarkers for risk stratification.

28. Paradigm shift in oncology: targeting the immune system rather than cancer cells

Abstract: The clinical benefits obtained with rituximab in the treatment of CD20(+) B-cell malignancies and of imatinib in the treatment of Phi(+) leukaemias have opened a new era in oncology, transforming the concepts of tumour-targeted therapies and personalised medicine into reality. Since then, many tumour-targeted monoclonal antibodies and tyrosine kinase inhibitors have been approved for the treatment of cancers. Compared to conventional chemotherapies, these new drugs have more specificity against cancer cells and less systemic toxicities. However, like conventional chemotherapies, they often provide limited therapeutic benefits with short-lasting tumour responses as the vast majority of cancers become resistant to these drugs over time. Therefore, tumour-targeted therapies are an incremental innovation as compared to historical chemotherapies. Recently, a paradigm shift has been brought to the clinic with drugs targeting immune cells rather than cancer cells with the aim of stimulating the anti-tumour immune response of patients against their own cancer. Immunomodulatory drugs such as anti-CTLA4 and anti-PD-1 have generated long-lasting tumour responses when used as single agent in patients with refractory/relapsing cancers such as metastatic melanomas, renal cell carcinoma or non-small-cell lung carcinoma. These new immune-targeted therapies are therefore a disruptive innovation in cancer treatment: they demonstrate that long-lasting clinical benefits could be obtained by targeting molecules involved in the immune tolerance of cancer cells rather than by targeting oncogenic drivers or antigens expressed by cancer cells.
