Abstract
Blinatumomab is a BiTE® (bispecific T-cell engager) molecule that redirects CD3+ T-cells to engage and lyse CD19+ target cells. Here we demonstrate that subcutaneous (SC) blinatumomab can provide high efficacy and greater convenience of administration. In the expansion phase of a multi-institutional phase 1b trial (ClinicalTrials.gov, NCT04521231), heavily pretreated adults with relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL) received SC blinatumomab at two doses: (1) 250 μg once daily (QD) for week 1 and 500 μg three times weekly (TIW) thereafter (250 μg/500 μg) or (2) 500 μg QD for week 1 and 1000 μg TIW thereafter (500 μg/1000 μg). The primary endpoint was complete remission/complete remission with partial hematologic recovery (CR/CRh) within two cycles. At the data cutoff of September 15, 2023, 29 patients were treated: 14 at the 250 μg/500 μg dose and 13 at 500 μg/1000 μg dose. Data from two ineligible patients were excluded. At the end of two cycles, 12 of 14 patients (85.7%) from the 250 μg/500 μg dose achieved CR/CRh of which nine patients (75.0%) were negative for measurable residual disease (MRD; <10-4 leukemic blasts). At the 500 μg/1000 μg dose, 12 of 13 patients (92.3%) achieved CR/CRh; all 12 patients (100.0%) were MRD-negative. No treatment-related grade 4 cytokine release syndrome (CRS) or neurologic events (NEs) were reported. SC injections were well tolerated and all treatment-related grade 3 CRS and NEs responded to standard-of-care management, interruption, or discontinuation. Treatment with SC blinatumomab resulted in high efficacy, with high MRD-negativity rates and acceptable safety profile in heavily pretreated adults with R/R B-ALL.

Abstract
BACKGROUND CD40, a TNF receptor family member, is expressed by a variety of immune cells and is involved in the activation of both adaptive and innate immune responses. Here, we used quantitative immunofluorescence (QIF) to evaluate CD40 expression on the tumor epithelium of solid tumors in large patient cohorts of lung, ovarian, and pancreatic cancers. METHODS Tissue samples from nine different solid tumors (bladder, breast, colon, gastric, head and neck, non-small cell lung cancer (NSCLC), ovarian, pancreatic and renal cell carcinoma), constructed in tissue microarray format, were initially assessed for CD40 expression by QIF. CD40 expression was then evaluated on the large available patient cohorts for three of the tumor types demonstrating high CD40 positivity rate; NSCLC, ovarian and pancreatic cancer. The prognostic impact of CD40 expression on tumor cells was also investigated. RESULTS CD40 expression on tumor cells was found to be common, with 80% of the NSCLC population, 40% of the ovarian cancer population, and 68% of the pancreatic adenocarcinoma population displaying some degree of CD40 expression on cancer cells. All of three of these cancer types displayed considerable intra-tumoral heterogeneity of CD40 expression, as well as partial correlation between expression of CD40 on tumor cells and on surrounding stromal cells. CD40 was not found to be prognostic for overall survival in NSCLC, ovarian cancer, or pancreatic adenocarcinoma. CONCLUSIONS The high percentage of tumor cells expressing CD40 in each of these solid tumors should be considered in the development of therapeutic agents designed to target CD40.

Abstract
This open-label, multicenter, single-arm, phase 2 study assessed the safety and efficacy of blinatumomab consolidation therapy in adult patients with newly diagnosed, high-risk diffuse large B-cell lymphoma (DLBCL; International Prognostic Index 3-5 and/or double-/triple-hit or double MYC/BCL-2 expressors) who achieved complete response (CR), partial response (PR), or stable disease (SD) following run-in with 6 cycles of R-chemotherapy (NCT03023878). Of the 47 patients enrolled, 28 received blinatumomab. Five patients (17.9%) experienced grade 4 treatment-emergent adverse events of interest (neutropenia, n = 4; infection, n = 1). Two deaths reported at the end of the study were unrelated to treatment with blinatumomab (disease progression, n = 1; infection, n = 1). 3/4 patients with PR and 4/4 patients with SD after R-chemotherapy achieved CR following blinatumomab. Consolidation with blinatumomab in patients with newly diagnosed, high-risk DLBCL who did not progress under R-chemotherapy was better tolerated than in previous studies where blinatumomab was used for treatment of patients with lymphoma.

Abstract
Abstract
The gut microbiome is an important determinant for the success of anti-tumor therapies including chemotherapeutics and anti-checkpoint inhibitors. In this study we wanted to leverage Second Genome’s large and curated microbiome database coupled with its proprietary bioinformatics and machine learning tools to discover bioactive peptides from Bifidobacteria that have the potential to drive response to immunotherapy. The genome of Bifidobacterium (B.) breve and B. longum were analyzed for proteins which were potentially secreted, and had unknown functions. 50 peptides were chemically synthesized and then screened in cell based assays for T cell activation and cytokine secretion. In the present study we describe one such novel B. breve-derived 42-aa peptide (SG-3-0020). The peptide stimulated secretion of effector cytokines by in vitro-cultured T cells (IFNg, TNF-a, IL-10 and IL-2) and increased the expression of PD-1 on both CD4+ and CD8+ T cells when stimulated with low-dose anti-CD3 antibody. To identify the binding partners and mechanism of action of the peptide, Mass Spec and Single-cell RNA-seq was used. Mass spec analysis showed that SG-3-05308, a variant of SG-3-0020 binds to a transmembrane glycoprotein of the immunoglobulin superfamily. Silencing this gene via CRISPR-Cas significantly decreased PD1 levels, cell proliferation and IFNg production in human pan T cells. Single cell RNA-seq data showed that SG-3-0020 activates NF-kB signaling and modulates calcium signaling in T cells. The potency of SG-3-0020 was further optimized for binding to activated T cells by using alanine scanning, saturation, and combinatorial mutation libraries using phage display. The results of protein engineering demonstrated that the 13 amino acids from the C-terminus of SG-3-0020 were not critical for binding and a 29-aa long (lacking the C-term) peptide stimulated increased IFNg production in human T cells across multiple human donors in a dose dependent manner. The peptide with the highest potency SG-3-05429 was selected for further understanding of how it interacts with the identified glycoprotein target and activates downstream T cell signaling pathways . Collectively, these data suggest that SG-3-0020’s ability to up-regulate key co-stimulatory and checkpoint molecules on T cells provides a strong rationale for its potential future use in combination with IO. These results validate the capability of the Second Genome drug discovery platform to identify novel microbial peptides/proteins of potential therapeutic relevance in IO and demonstrate a unique approach that can identify microbial derived bioactive molecules involved in modulating immune cell effector functions and/or immune cell differentiation.

Abstract
The composition of the gut microbiota affects cancer development, progression, and response to therapy. A number of commensal bacteria, including Bifidobacterium, have been associated with increased response to immune checkpoint inhibitors in mouse tumor models, as well as in melanoma patients. We hypothesized that secreted peptides or proteins contribute to the effects mediated by Bifidobacterium strains in vivo. We used our unique bioinformatics-driven discovery platform to nominate putatively secreted Bifidobacterium-derived peptides for evaluation in immune cell effector assays. We have previously described bacterial peptides that induce secretion of proinflammatory cytokines (e.g., IL-6, TNF) by in vitro-generated mouse and human dendritic cells, as well as effector cytokine secretion (e.g., IFNγ, IL-2) by mouse splenic T lymphocytes in vitro. To investigate the function of Bifidobacterium-derived peptides in the context of the tumor microenvironment, we injected a candidate peptide, termed SG-A, directly into the tumors of tumor-bearing mice. We then performed immune phenotyping via the Nanostring PanCancer Immune Profiling panel, as well as by flow cytometry. Both Nanostring and flow cytometry analysis demonstrated an increase in CD45+ lymphocytes within the tumors of mice treated with SG-A. Peptide SG-A also induced upregulation of dendritic cell function genes (CD40, CD83, and CD86) and multiple effector cytokines and chemokines. Restimulation of tumor-draining lymph node cells with a tumor-derived peptide antigen also increased induction of IFNγ in SG-A treated animals (vs. vehicle-treated controls). Collectively, our results demonstrate the utility of the Second Genome discovery platform for leveraging microbiome science to identify novel immunomodulatory factors. This platform offers the potential to identify agents that may complement or enhance efficacy of existing approaches to immunotherapy for melanoma and other cancers.

Abstract
The gut microbiome is a key contributor to the maintenance of host physiology. At the same time, increasing evidence implicates microbiome dysbiosis as a key determinant of numerous metabolic and inflammatory disorders. It is, therefore, of paramount importance to understand the interactions between the host and gut microbiota. Second Genome has developed a proprietary, bioinformatics-driven discovery platform to identify novel microbiome-derived peptides with the potential to modulate host immune responses. We have leveraged this platform to evaluate immunomodulatory functions of novel, secreted peptides derived from gut-resident bacterial species Bifidobacterium longum and Bifidobacterium breve. Previously, the microbial genus Bifidobacterium (‘Bifido’) has been shown to be associated with enhanced dendritic cell functions and antitumor effects. Here, we identify Bifido-derived peptides that are putative agonists of certain murine and human Toll-like receptors (TLRs). These peptides induce secretion of pro-inflammatory cytokines such as TNF-α and IL-6 by in vitro-generated mouse dendritic cells and peritoneal macrophages in a TLR4 and CD14-dependent manner. One of the peptides, SG-A, also induces secretion of Th1-type cytokines and chemokines such as IL-21, GRO-α, and IP-10 by human monocytes and monocyte-derived dendritic cells. Moreover, in vivo administration of SG-A in mice elicited a systemic pro-inflammatory immune response in the absence of any secondary stimulus. Collectively, our results demonstrate the ability of a novel bacterial-derived peptide to engage the host innate immune system. Moreover, our findings validate the potential of the Second Genome discovery platform for identification of novel microbiome-derived agents that: i) have the ability to modulate host cell functions; and ii) may be developed into therapeutic agents for immune and inflammatory disorders.

The composition of the gut microbiota affects cancer development, progression, and response to therapy. A number of commensal bacteria, including Bifidobacterium, have been associated with increased response to immune checkpoint inhibitors in mouse tumor models and in cancer patients.
We hypothesized that secreted peptides or proteins are driving the Bifidobacterium-mediated effects. Using our unique bioinformatic-driven discovery platform we nominated putatively secreted Bifidobacterium-derived peptides for evaluation in immune cell effector assays. We demonstrate that several of the peptides induce secretion of pro-inflammatory cytokines (e.g., IL-6, TNF) by in vitro-generated mouse and human dendritic cells, as well as effector cytokine secretion (e.g., IFNγ, IL-2) by mouse splenic T lymphocytes in vitro.
To investigate the function of Bifidobacterium-derived peptides in the context of the tumor microenvironment we injected the candidate peptide SG-A directly into the tumor of CT26 tumor-bearing mice and analyzed the immune phenotype using the Nanostring PanCancer Immune Profiling panel and flow cytometry. Both Nanostring as well as flow cytometry analysis showed an increase in CD45+ tumor-infiltrating lymphocytes in SG-A treated tumors. SG-A peptide also induced the upregulation of dendritic cell function genes (CD40, CD83, and CD86) and multiple effector cytokines and chemokines. Re-stimulation of tumor-draining lymph node cells with AH1 peptide (a CT26 tumor-derived antigen) also increased induction of IFNγ in SG-A treated animals (vs. vehicle-treated controls).
Collectively, our results demonstrate the utility of the Second Genome discovery platform for leveraging microbiome science to identify novel immunoregulatory factors. This platform offers a promising approach to identify agents with potential for use as therapeutics in cancer immunotherapy.

Abstract
Mouse syngeneic tumor models are widely used tools to demonstrate activity of novel anti-cancer immunotherapies. Despite their widespread use, a comprehensive view of their tumor-immune compositions and their relevance to human tumors has only begun to emerge. We propose each model possesses a unique tumor-immune infiltrate profile that can be probed with immunotherapies to inform on anti-tumor mechanisms and treatment strategies in human tumors with similar profiles. In support of this endeavor, we characterized the tumor microenvironment of four commonly used models and demonstrate they encompass a range of immunogenicities, from highly immune infiltrated RENCA tumors to poorly infiltrated B16F10 tumors. Tumor cell lines for each model exhibit different intrinsic factors in vitro that likely influence immune infiltration upon subcutaneous implantation. Similarly, solid tumors in vivo for each model are unique, each enriched in distinct features ranging from pathogen response elements to antigen presentation machinery. As RENCA tumors progress in size, all major T cell populations diminish while myeloid-derived suppressor cells become more enriched, possibly driving immune suppression and tumor progression. In CT26 tumors, CD8 T cells paradoxically increase in density yet are restrained as tumor volume increases. Finally, immunotherapy treatment across these different tumor-immune landscapes segregate into responders and non-responders based on features partially dependent on pre-existing immune infiltrates. Overall, these studies provide an important resource to enhance our translation of syngeneic models to human tumors. Future mechanistic studies paired with this resource will help identify responsive patient populations and improve strategies where immunotherapies are predicted to be ineffective.

Abstract
Abstract
Inducible T-cell costimulator (ICOS) is a costimulatory receptor that is upregulated on activated CD4 and CD8 T cells and plays an important role in T cell survival, differentiation, regulation of memory and regulatory T cell pools and humoral responses. Preclinically, augmenting signaling through the ICOS pathway has been reported to induce anti-tumor activity and enhance responses to CTLA4 blockade.
Here we present non-clinical data evaluating ICOS agonist antibody activity in human and mouse model systems using a different antibody for each species. GSK3359609 is a novel, selective anti-human ICOS agonist. GSK3359609 induces ICOS signaling through phosphorylation of intermediates in the Pi3K pathway leading to lymphocyte activation, proliferation and pro-inflammatory cytokine secretion in human PBMC in-vitro. A robust increase in CD4 effector T cell proliferation and Granzyme B secreting CD8 T cells was observed with GSK3359609 treatment in in-vitro assays utilizing PBMC from healthy donors, cancer patients or tumor infiltrating lymphocytes (TIL). Modest induction of regulatory T cell proliferation and IL-10 secretion were also observed. Significant increase in IFNγ (p<0.05) and TNFα secretion was observed in both primary PBMC and TIL based assays. Gene expression analysis of GSK3359609 treated human T cells confirmed changes in genes associated with T and B cell activation. In mice, an ICOS surrogate antibody was utilized in immune competent mouse tumor models. Tumor regressions were observed in 10-40% of mice and were associated with a robust increase in effector memory T cells in periphery as well as increases in T cell activation and proliferation in lymphoid tissues and tumor. Robust increases in PD1, PD-L1 and PD-L2 gene expression were observed in the tumors from ICOS antibody treated mice along with an increase in cytotoxic T cell signature and induction of an IFNγ gene signature. Changes in regulatory T cell proliferation were also observed in the blood and tumor of mice treated with the mouse ICOS agonist however changes were consistently less in magnitude than corresponding functional changes in cytotoxic CD8+ and effector CD4 cells.
We further explored treatment settings where a combination therapy may condition the tumor immune microenvironment to a more favorable context for ICOS agonist therapy. Treatment with an anti-PD1 antibody resulted in strong upregulation of ICOS expression on tumor infiltrating CD8, CD4 effector and regulatory T cells while decreasing ICOS+ Tregs relative to CD8 and CD4 effectors in the tumor microenvironment. Synergistic anti-tumor activity was observed for the combination of PD-1 with ICOS agonist antibodies in preclinical studies. These studies provide a strong rationale for the ongoing FTIH Phase I study of GSK3359609 administered alone and in combination with pembrolizumab to patients with selected advanced solid tumors.
