Abstract: The prognosis of early breast cancer (BC) relies on cell autonomous and immune parameters. The impact of the intestinal microbiome on clinical outcome has not yet been evaluated. Shotgun metagenomics was used to determine the composition of the fecal microbiota in 121 specimens from 76 early BC patients, 45 of whom were paired before and after chemotherapy. These patients were enrolled in the CANTO prospective study designed to record the side effects associated with the clinical management of BC. We analyzed associations between baseline or post-chemotherapy fecal microbiota and plasma metabolomics with BC prognosis, as well as with therapy-induced side effects. We examined the clinical relevance of these findings in immunocompetent mice colonized with BC patient microbiota that were subsequently challenged with histo-compatible mouse BC and chemotherapy. We conclude that specific gut commensals that are overabundant in BC patients compared with healthy individuals negatively impact BC prognosis, are modulated by chemotherapy, and may influence weight gain and neurological side effects of BC therapies. These findings obtained in adjuvant and neoadjuvant settings warrant prospective validation.

Abstract: International audience; Hepatic arterial infusion (HAI) of oxaliplatin allows greater liver tumour drug exposure compared to systemic infusion. However, the therapeutic index of HAI oxaliplatin remains poor. Using Pickering emulsion technology, we developed a platform able to provide sustained releases of oxaliplatin. The goal of this study was to evaluate the pharmacokinetic advantages of sustained-HAI oxaliplatin over HAI using a preclinical animal tumour model. Injections of 0.6 mg oxaliplatin in 20 min were selectively done in left hepatic arteries of 20 rabbits bearing a VX2 liver tumour in the middle left-lobe, using HAI (n = 10) or sustained-HAI (n = 10). In each group, half of the rabbits were sacrificed at 24 h and half at 72 h. Mass spectrometry was used to quantify drug pharmacokinetics in blood and oxaliplatin concentrations in tumour tissues, right- and middle left-liver lobes, spleen and lung. Compared to HAI, sustained-HAI of oxaliplatin resulted in lower plasmatic peak (Cmax: 275 ± 41 vs. 416 ± 133 ng/mL, p = 0.02) and higher concentration in the tumour at 24 h (2118 ± 2107 vs. 210 ± 93 ng/g, p = 0.008). After HAI, oxaliplatin concentration in tumours was significantly higher than in lung at 24 h (p = 0.03) but no other difference was found between oxaliplatin concentrations in tumours and in liver lobes, spleen or lung, neither at 24 h nor at 72 h. On the opposite, sustained-HAI resulted in higher concentrations of oxaliplatin in tumour compared to oxaliplatin concentrations in the middle left lobe (163 ± 86 ng/g at 24 h, p = 0.01, and 90 ± 15 ng/g at 72 h, p = 0.04), right lobe (174 ± 112 ng/g at 24 h, p = 0.01, and 112 ± 35 ng/g, p = 0.04 at 72 h), spleen (142 ± 21 ng/g at 24 h, p = 0.01, and 98 ± 12 ng/g at 72 h, p = 0.04), and lung (85 ± 11 ng/g at 24 h, p = 0.01, and 52 ± 4 ng/g at 72 h, p = 0.03). Sustained-HAI improves the therapeutic index of HAI oxaliplatin and offers a great potential for patients suffering from unresectable colorectal liver metastases or hepatocellular carcinoma.

Abstract: International audience; Background: Plasmacytoid urothelial carcinoma (UC) is a rare pathological variant of UC with low chemotherapeutic sensitivity and dismal outcomes. The molecular and immune profiles of such tumors remain poorly investigated. Methods: Herein, we investigated the phenotypical features of a cohort of plasmacytoid UC (n=32) by comparison to a control group of conventional high-grade UC with matched clinicopathological characteristics (n=30). Histopathological analysis included the following antibodies: p63, GATA3, CK5/6, CK20 and HER2. In addition, the density of intra-tumor CD8+ lymphocytes, and PD-L1 expression in tumor (TC) and immune cells (IC) were evaluated. Results: Plasmacytoid UC expressed GATA3 (97% vs 86% P=0.18), CK20 (59% vs 36% P=0.08) markers and showed a significantly higher rate of HER2 overexpression (2+ and 3+ score: 25% vs 0%, P

Abstract: Tissue macrophages are immune cells whose phenotypes and functions are dictated by origin and niches. However, tissues are complex environments, and macrophage heterogeneity within the same organ has been overlooked so far. Here, we used high-dimensional approaches to characterize macrophage populations in the murine liver. We identified two distinct populations among embryonically derived Kupffer cells (KCs) sharing a core signature while differentially expressing numerous genes and proteins: a major CD206loESAM– population (KC1) and a minor CD206hiESAM+ population (KC2). KC2 expressed genes involved in metabolic processes, including fatty acid metabolism both in steady-state and in diet-induced obesity and hepatic steatosis. Functional characterization by depletion of KC2 or targeted silencing of the fatty acid transporter Cd36 highlighted a crucial contribution of KC2 in the liver oxidative stress associated with obesity. In summary, our study reveals that KCs are more heterogeneous than anticipated, notably describing a subpopulation wired with metabolic functions.

Abstract: International audience; Treatment with combined immune checkpoint blockade (CICB) targeting CTLA-4 and PD-1 is associated with clinical benefit across tumor types, but also a high rate of immune-related adverse events. Insights into biomarkers and mechanisms of response and toxicity to CICB are needed. To address this, we profiled the blood, tumor and gut microbiome of 77 patients with advanced melanoma treated with CICB, with a high rate of any ≥grade 3 immune-related adverse events (49%) with parallel studies in pre-clinical models. Tumor-associated immune and genomic biomarkers of response to CICB were similar to those identified for ICB monotherapy, and toxicity from CICB was associated with a more diverse peripheral T-cell repertoire. Profiling of gut microbiota demonstrated a significantly higher abundance of Bacteroides intestinalis in patients with toxicity, with upregulation of mucosal IL-1β in patient samples of colitis and in pre-clinical models. Together, these data offer potential new therapeutic angles for targeting toxicity to CICB.

Abstract: International audience; Immunotherapy has revolutionized cancer treatment and substantially improved patient outcome with regard to multiple tumour types. However, most patients still do not benefit from such therapies, notably because of the absence of pre-existing T cell infiltration. DNA damage response (DDR) deficiency has recently emerged as an important determinant of tumour immunogenicity. A growing body of evidence now supports the concept that DDR-targeted therapies can increase the antitumour immune response by (1) promoting antigenicity through increased mutability and genomic instability, (2) enhancing adjuvanticity through the activation of cytosolic immunity and immunogenic cell death and (3) favouring reactogenicity through the modulation of factors that control the tumour–immune cell synapse. In this Review, we discuss the interplay between the DDR and anticancer immunity and highlight how this dynamic interaction contributes to shaping tumour immunogenicity. We also review the most innovative preclinical approaches that could be used to investigate such effects, including recently developed ex vivo systems. Finally, we highlight the therapeutic opportunities presented by the exploitation of the DDR–anticancer immunity interplay, with a focus on those in early-phase clinical development.

Abstract: International audience; A deviated repertoire of the gut microbiome predicts resistance to cancer immunotherapy. Enterococcus hirae compensated cancer-associated dysbiosis in various tumor models. However, the mechanisms by which E. hirae restored the efficacy of cyclophosphamide administered with concomitant antibiotics remain ill defined. Here, we analyzed the multifaceted modes of action of this anticancer probiotic. Firstly, E. hirae elicited emigration of thymocytes and triggered systemic and intratumoral IFN gamma-producing and CD137-expressing effector memory T cell responses. Secondly, E. hirae activated the autophagy machinery in enterocytes and mediated ATG4B-dependent anticancer effects, likely as a consequence of its ability to increase local delivery of polyamines. Thirdly, E. hirae shifted the host microbiome toward a Bifidobacteria-enriched ecosystem. In contrast to the live bacterium, its pasteurized cells or membrane vesicles were devoid of anticancer properties. These pleiotropic functions allow the design of optimal immunotherapies combining E. hirae with CD137 agonistic antibodies, spermidine, or Bifidobacterium animalis. We surmise that immunological, metabolic, epithelial, and microbial modes of action of the live E. hirae cooperate to circumvent primary resistance to therapy.

Abstract: The circulating metabolome provides a snapshot of the physiological state of the organism responding to pathogenic challenges. Here we report alterations in the plasma metabolome reflecting the clinical presentation of COVID-19 patients with mild (ambulatory) diseases, moderate disease (radiologically confirmed pneumonitis, hospitalization and oxygen therapy), and critical disease (in intensive care). This analysis revealed major disease- and stage-associated shifts in the metabolome, meaning that at least 77 metabolites including amino acids, lipids, polyamines and sugars, as well as their derivatives, were altered in critical COVID-19 patient’s plasma as compared to mild COVID-19 patients. Among a uniformly moderate cohort of patients who received tocilizumab, only 10 metabolites were different among individuals with a favorable evolution as compared to those who required transfer into the intensive care unit. The elevation of one single metabolite, anthranilic acid, had a poor prognostic value, correlating with the maintenance of high interleukin-10 and -18 levels. Given that products of the kynurenine pathway including anthranilic acid have immunosuppressive properties, we speculate on the therapeutic utility to inhibit the rate-limiting enzymes of this pathway including indoleamine 2,3-dioxygenase and tryptophan 2,3-dioxygenase.

Abstract: The success of cancer immunotherapy relies on the induction of an immunoprotective response targeting tumor antigens (TAs) presented on MHC-I molecules. We demonstrated that the splicing inhibitor isoginkgetin and its water-soluble and non-toxic derivative IP2 act at the production stage of the pioneer translation products (PTPs). We showed that IP2 increases PTP-derived antigen presentation in cancer cells in vitro and impairs tumor growth in vivo. IP2 action is long-lasting and dependent on the CD8+ T cell response against TAs. We observed that the antigen repertoire displayed on MHC-I molecules at the surface of MCA205 fibrosarcoma is modified upon treatment with IP2. In particular, IP2 enhances the presentation of an exon-derived epitope from the tumor suppressor nischarin. The combination of IP2 with a peptide vaccine targeting the nischarin-derived epitope showed a synergistic antitumor effect in vivo. These findings identify the spliceosome as a druggable target for the development of epitope-based immunotherapies., Darrigrand, Pierson et al. study the effect of mRNA splicing inhibitors on the generation of the MHC class I ligands. They developed a derivative of the spliceosome inhibitor isoginkgetin which is less toxic and more effective at enhancing antigen presentation and CD8+ T cell activation and showed greater antitumour activity in vivo. These findings identify the spliceosome as a druggable target for the development of epitope-based immunotherapies.

Abstract: For anthracycline-based chemotherapy to be immunogenic, dying cancer cells must release annexin A1 (ANXA1) that subsequently interacts with the pattern recognition receptor, formyl peptide receptor 1 (FPR1), on the surface of dendritic cells (DC). Approximately 30% of individuals bear loss-of-function alleles of FPR1, calling for strategies to ameliorate their anticancer immune response. Here, we show that immunotherapy with a ligand of Toll-like receptor-3, polyinosinic:polycytidylic acid (pIC), restores the deficient response to chemotherapy of tumors lacking ANXA1 developing in immunocompetent mice or those of normal cancers growing in FPR1-deficient mice. This effect was accompanied by improved DC- and T-lymphocyte–mediated anticancer immunity. Of note, carcinogen-induced breast cancers precociously developed in FPR1-deficient mice as compared with wild-type controls. A similar tendency for earlier cancer development was found in patients carrying the loss-of-function allele of FPR1. These findings have potential implications for the clinical management of FPR1-deficient patients. Significance: The loss-of-function variant rs867228 in FPR1, harbored by approximately 30% of the world population, is associated with the precocious manifestation of breast, colorectal, esophageal, and head and neck carcinomas. pIC restores deficient chemotherapeutic responses in mice lacking Fpr1, suggesting a personalized strategy for compensating for the FPR1 defect.

Abstract: International audience; Intestinal microbiota have been proposed to induce commensal-specific memory T cells that cross-react with tumor-associated antigens. We identified major histocompatibility complex (MHC) class I-binding epitopes in the tail length tape measure protein (TMP) of a prophage found in the genome of the bacteriophage Enterococcus hirae Mice bearing E. hirae harboring this prophage mounted a TMP-specific H-2Kb-restricted CD8+ T lymphocyte response upon immunotherapy with cyclophosphamide or anti-PD-1 antibodies. Administration of bacterial strains engineered to express the TMP epitope improved immunotherapy in mice. In renal and lung cancer patients, the presence of the enterococcal prophage in stools and expression of a TMP-cross-reactive antigen by tumors correlated with long-term benefit of PD-1 blockade therapy. In melanoma patients, T cell clones recognizing naturally processed cancer antigens that are cross-reactive with microbial peptides were detected.

Abstract: International audience; Patients with relapsed/refractory Hodgkin lymphoma (R/R HL) experience high response rates upon anti-PD1 therapy. In these patients, there is limited data about the optimal duration of treatment and the risk of relapse after anti-PD1 discontinuation. We have previously reported the outcome of 11 patients with R/R HL who discontinued anti-PD1 therapy after achieving a complete response (CR) upon nivolumab1 . These patients experienced favorable outcome as only 2 of them had relapsed after a median follow-up of 21.2 months from discontinuation. Despite the low relapse rate observed in that study, physicians may be worried about the possibility to further rescue these heavily pre-treated patients in case of relapse after anti-PD1 discontinuation. Notably, it is still unknown whether these patients will remain sensitive to a 2nd course of anti-PD1.

Abstract: Lytic transglycosylases (LT) are enzymes involved in peptidoglycan (PG) remodeling. However, their contribution to cell-wall-modifying complexes and their potential as antimicrobial drug targets remains unclear. Here, we determined a high-resolution structure of the LT, an outer membrane lipoprotein from Neisseria species with a disordered active site helix (alpha helix 30). We show that deletion of the conserved alpha-helix 30 interferes with the integrity of the cell wall, disrupts cell division, cell separation, and impairs the fitness of the human pathogen Neisseria meningitidis during infection. Additionally, deletion of alpha-helix 30 results in hyperacetylated PG, suggesting this LtgA variant affects the function of the PG de-O-acetylase (Ape 1). Our study revealed that Ape 1 requires LtgA for optimal function, demonstrating that LTs can modulate the activity of their protein-binding partner. We show that targeting specific domains in LTs can be lethal, which opens the possibility that LTs are useful drug-targets., eLife digest Bacteria are surrounded by a tough yet flexible wall that protects the cell and serves as an anchor for several of the cell’s structures. This cell wall contains a large mesh-like molecule called peptidoglycan made of many repeated building blocks. When a bacterial cell divides in two, it needs to make more of this material. Making peptidoglycan involves two different sets of enzymes working together: “polymerases” are the enzymes that link the individual building blocks to peptidoglycan, one after the other; while “lytic transglycosylases” are enzymes that modify the peptidoglycan to create space for the addition of new building blocks and for assemblies of proteins that must span the cell wall. Lytic transglycosylases are known to assemble with other proteins and enzymes to form the cell’s peptidoglycan-modifying machinery, but it was not clear exactly what purpose they serve within these “enzyme complexes”. It was also unclear whether these enzymes would be good targets for new antibiotics. To help answer these questions, Williams et al. looked at a lytic transglycoslyase called LtgA. This enzyme is originally from Neisseria meningitidis, a bacterium that can cause meningitis and life-threatening sepsis in humans. Williams et al. discovered that part of the enzyme’s active site – the region of an enzyme where the chemical reaction takes – can switch from an ordered helix to a disordered, flexible loop. Bacteria were then genetically engineered to make a version of the enzyme that lacked this helix. These bacteria had weaker cell walls and were deformed; they were also less able to grow and divide, both in the laboratory and in a mouse model of infection. Further analysis showed that the deletion of the helix from the enzyme resulted in the peptidoglycan being modified much more than normal, which could likely explain their reduced virulence. Williams et al. also found that deleting the helix from LtgA interfered with the activity of a protein that interacts with this enzyme, called Ape1, which also contributed to the fragility of the cell wall. This shows that lytic transglycosylases assembled into enzyme complexes can alter the activities of other proteins in the complex. Together these findings show that researchers could target one enzyme in a complex in bacteria, and disrupt the activity of other proteins in that complex. This highlights the possibility of considering enzyme complexes as useful targets for new drugs, which is important considering the current problem of antibiotic resistance.

Abstract: International audience; Coronavirus disease 2019 (COVID-19) and its causative virus, SARS-CoV-2, pose considerable challenges for the management of oncology patients. COVID-19 presents as a particularly severe respiratory and systemic infection in aging and immunosuppressed individuals, including patients with cancer. Moreover, severe COVID-19 is linked to an inflammatory burst and lymphopenia, which may aggravate cancer prognosis. Here we discuss why those with cancer are at higher risk of severe COVID-19, describe immune responses that confer protective or adverse reactions to this disease and indicate which antineoplastic therapies may either increase COVID-19 vulnerability or have a dual therapeutic effect on cancer and COVID-19. Zitvogel and colleagues discuss the interplay between cancer and COVID-19 with respect to patient risk and prognosis, immune responses and potential therapies.

Abstract: Background: The development of immune checkpoint blockade (ICB) has revolutionized the clinical outcome of renal cell carcinoma (RCC). Nevertheless, improvement of durability and prediction of responses remain unmet medical needs. While it has been recognized that antibiotics (ATBs) decrease the clinical activity of ICB across various malignancies, little is known about the direct impact of distinct intestinal nonpathogenic bacteria (commensals) on therapeutic outcomes of ICB in RCC. Objective: To evaluate the predictive value of stool bacteria composition for ICB efficacy in a cohort of advanced RCC patients. Design, setting, and participants: We prospectively collected fecal samples from 69 advanced RCC patients treated with nivolumab and enrolled in the GETUG-AFU 26 NIVOREN microbiota translational substudy phase 2 trial (NCT03013335) at Gustave Roussy. We recorded patient characteristics including ATB use, prior systemic therapies, and response criteria. We analyzed 2994 samples of feces from healthy volunteers (HVs). In parallel, preclinical studies performed in RCC-bearing mice that received fecal transplant (FMT) from RCC patients resistant to ICB (NR-FMT) allowed us to draw a cause-effect relationship between gut bacteria composition and clinical outcomes for ICB. The influence of tyrosine kinase inhibitors (TKIs) taken before starting nivolumab on the microbiota composition has also been assessed. Outcome measurements and statistical analysis: Metagenomic data (MG) from whole genome sequencing (WGS) were analyzed by multivariate and pairwise comparisons/fold ratio to identify bacterial fingerprints related to ATB or prior TKI exposure and patients’ therapeutic response (overall response and progression-free survival), and compared with the data from cancer-free donors. Results and limitations: Recent ATB use (n = 11; 16%) reduced objective response rates (from 28% to 9%, p < 0.03) and markedly affected the composition of the microbiota, facilitating the dominance of distinct species such as Clostridium hathewayi, which were also preferentially over-represented in stools from RCC patients compared with HVs. Importantly, TKIs taken prior to nivolumab had implications in shifting the microbiota composition. To establish a cause-effect relationship between gut bacteria composition and ICB efficacy, NR-FMT mice were successfully compensated with either FMT from responding RCC patients or beneficial commensals identified by WGS-MG (Akkermansia muciniphila and Bacteroides salyersiae). Conclusions: The composition of the microbiota is influenced by TKIs and ATBs, and impacts the success of immunotherapy. Future studies will help sharpen the role of these specific bacteria and their potential as new biomarkers. Patient summary: We used quantitative shotgun DNA sequencing of fecal microbes as well as preclinical models of fecal or bacterial transfer to study the association between stool composition and (pre)clinical outcome to immune checkpoint blockade. Novel insights into the pathophysiological relevance of intestinal dysbiosis in the prognosis of kidney cancer may lead to innovative therapeutic solutions, such as supplementation with probiotics to prevent primary resistance to therapy. Antibiotics prior to immune checkpoint inhibitors have a deleterious clinical impact, reduce the microbiome diversity, and increase Clostridium hathewayi bacteria associated with resistance. Higher baseline microbiome diversity and Akkermansia muciniphila are associated with longer progression-free survival. In murine fecal microbiome transplantation experiments, A. muciniphila can restore the anticancer activity of the combination of anti–PD-1 and CTLA-4.

Abstract: International audience; Accumulating evidence from preclinical studies and human trials demonstrated the crucial role of the gut microbiota in determining the effectiveness of anticancer therapeutics such as immunogenic chemotherapy or immune checkpoint blockade. In summary, it appears that a diverse intestinal microbiota supports therapeutic anticancer responses, while a dysbiotic microbiota composition that lacks immunostimulatory bacteria or contains overabundant immunosuppressive species causes treatment failure. In this review, we explore preclinical and translational studies highlighting how eubiotic and dysbiotic microbiota composition can affect progression-free survival in cancer patients.

Abstract: Contains fulltext : 220857.pdf (Publisher’s version ) (Open Access) Accumulating evidence demonstrates the decisive role of the gut microbiota in determining the effectiveness of anticancer therapeutics such as immunogenic chemotherapy or immune checkpoint blockade in preclinical tumor models, as well as in cancer patients. In synthesis, it appears that a normal intestinal microbiota supports therapeutic anticancer responses, while a dysbiotic microbiota that lacks immunostimulatory bacteria or contains overabundant immunosuppressive species causes treatment failure. These findings have led to the design of clinical trials that evaluate the capacity of modulation of the gut microbiota to synergize with treatment and hence limit tumor progression. Along the lines of this Trial Watch, we discuss the rationale for harnessing the gut microbiome in support of cancer therapy and the progress of recent clinical trials testing this new therapeutic paradigm in cancer patients.
