Background: Lysine-specific demethylase 1A (KDM1A) plays an important role in epigenetic regulation in malignant tumors and promotes cancer invasion and metastasis by blocking the immune response and suppressing cancer surveillance activities. The aim of this study was to analyze survival, genetic interaction networks and anticancer immune responses in breast cancer patients with high KDM1A expression and to explore candidate target drugs. Methods: We investigated clinicopathologic parameters, specific gene sets, immunologic relevance, pathway-based networks and in vitro drug response according to KDM1A expression in 456 and 789 breast cancer patients from the Hanyang university Guri Hospital (HYGH) and The Cancer Genome Atlas, respectively. Results: High KDM1A expression was associated with a low survival rate in patients with breast cancer. In analyses of immunologic gene sets, high KDM1A expression correlated with low immune responses. In silico flow cytometry results revealed low abundances of CD8+T cells and high programmed death-ligand 1 (PD-L1) expression in those with high KDM1A expression. High KDM1A expression was associated with a decrease in the anticancer immune response in breast cancer. In pathway-based networks, KDM1A was linked directly to pathways related to the androgen receptor signaling pathway and indirectly to the immune pathway and cell cycle. We found that alisertib effectively inhibited breast cancer cell lines with high KDM1A expression. Conclusions: Strategies utilizing KDM1A may contribute to better clinical management/research for patients with breast cancer.

BackgroundLadiratuzumab vedotin (LV) is an investigational antibody-drug conjugate (ADC) composed of a humanized anti-LIV-1 IgG1 conjugated with monomethyl auristatin E (MMAE), a microtubule-disrupting agent. LV targets LIV-1, a protein expressed by various cancers. Along with a cytotoxic effect, LV has been shown to induce immunogenic cell death (ICD) in preclinical studies. LV is currently being investigated as a monotherapy and in combination with pembrolizumab in patients with metastatic breast cancer and other solid tumors. This correlative biomarker study aims to assess the ability of LV to modulate the tumor microenvironment (TME) in breast cancer patients.MethodsIn the SGNLVA-001 trial, metastatic breast cancer patients, predominantly of the triple negative subtype (TNBC), received LV monotherapy (2.0 or 2.5 mg/kg, every 3 weeks [q3w]). In the SGNLVA-002 trial, patients with metastatic TNBC received LV (2.0 or 2.5 mg/kg, q3w) plus pembrolizumab (200 mg, q3w). To investigate the potential effect of LV or LV plus pembrolizumab on the TME, paired pre-treatment and on-treatment tumor biopsies (Cycle [C] 1 Day [D] 5 or C1D15) were collected and analyzed by RNAseq and immunohistochemistry (IHC) staining.ResultsGene expression analysis of paired biopsy TNBC samples (n=59; baseline and C1D5) showed that LV monotherapy treatment significantly induces immune response-related gene expression, MHC, co-stimulatory molecules, and PD-L1. Gene set enrichment analysis (GSEA) demonstrated enrichment of macrophage and tumor inflammation signature genes, supporting the induction of ICD and enhancement of innate immune response. Paired tumor samples from subjects treated with LV plus pembrolizumab (n=16; baseline and C1D15) showed a broader range of gene expression changes on RNAseq compared to LV monotherapy. GSEA evidenced enrichment of genes associated with cytotoxic CD8 T cells, CD4 T helper cells, dendritic cells, and macrophages, further demonstrating the induction of ICD and activation of an innate immune response. Importantly, the combination had a unique adaptive immune response induction signature. IHC analysis confirmed the increased infiltration of macrophages after LV monotherapy. The combination with pembrolizumab resulted in a further increase in macrophages and a prominent influx of CD8 T cells.ConclusionsSystemic administration of LV monotherapy resulted in immune activation in the TME and macrophage infiltration. The combination of LV plus pembrolizumab resulted in a more potent immune activation in the TME and a prominent influx of CD8 T cells in addition to macrophages. Together these results provide a rationale for the continued clinical investigation of LV alone or in combination with pembrolizumab.Trial RegistrationNCT01969643 and NCT03310957Ethics ApprovalThe study protocols for clinical trials represented in this publication were reviewed by the respective IRB/IEC at each study site and approved before trial participants were screened and enrolled.ConsentNot applicable.

2580 Background: Women with high risk breast cancer still succumb to their disease despite existing programs of adjuvant therapy. Thus, new approaches for adjuvant therapy are needed. Her-2-Neu overexpression on a breast cancer cells correlates with recurrence, metastasis and resistance to chemotherapy and radiation therapy. The immune response is tolerant of tumor associated antigens (TAA) like Her-2-Neu since they have been present on epithelial cells since birth. The immune response to vaccines in women with breast cancer is limited by the diminished number of CD4 and CD8 T cells and qualitative defects of CD4 cells in individuals above the age of 50. Methods: The following strains of mice were vaccinated: 6–8 week old hMUC-1.Tg mice, and rH2N.Tg mice, as well as 18 month and 2 month old C57BL/6J mice, by injecting subcutaneously the Ad-sig-TAA/ecdCD40L vector prime followed by sc injections of the TAA/ecdCD40L protein boost. Results: Vaccination of 18 month old mice with the Ad-sig-TAA/ecdCD40L vector prime protein boost produce regressions of TAA positive sc tumor and a 5 fold increase in antigen specific spleen cells, a 10X increase in subcutaneous tumor nodules of antigen specific effector CD8 T cells by tetramers, and a 2X decrease of CD4+CD25+FOXP3+ cells. Vaccination of rH2N.Tg mice starting at 6 weeks with the Ad-sig-rH2N/ecdCD40L vector prime/protein boost prevented the development of breast cancer in 50% of the mice. The Ad-sig-hMUC-1/ecdCD40L vector prime/ hMUC-1/ecdCD40L protein boost induced hMUC-1 specific antibodies in hMUC-1.Tg mice which bound to human breast cancer specimens. The rH2N/ecdCD40L vector prime/protein boost vaccine suppressed growth of rH2N positive tumor cells and this effect was potentiated by concomitant administration of chemotherapy. Conclusions: These results suggest that the Ad-sig-TAA/ecdCD40L platform can be used to suppress the growth of existing breast cancer even in old mice and prevent the development of breast cancer. We are preparing a phase I clinical trial of this approach in the setting of breast cancer patients who have failed first line adjuvant therapy. In this trial, the vaccine will be added to established salvage therapy and both in vivo evaluations of tumor response, in vitro assays of immune response and toxicity will be measured.

Matrix metalloproteinase-11 (MMP-11) promote cancer invasion and metastasis through degrading the extracellular matrix. Protein degradation by MMP-11 in tumor cells may progressively suppress cancer surveillance activities with blocking immune response in breast cancer. The aim of study is to analyze clinicopathological parameters, molecular interactions and anticancer immune response in patients with MMP-11 expression and to provide candidate target drugs. We investigated the clinicopathologic parameters, specific gene sets, tumor antigenicity, and immunologic relevance according to MMP-11 expression in 226 and 776 breast cancer patients from the Hanyang University Guri Hospital (HUGH) cohort and The Cancer Genome Atlas (TCGA) data, respectively. We analyzed pathway networks and in vitro drug response. High MMP-11 expression was associated with worse survival rate in breast cancer from HUGH cohort and TCGA data (all p < 0.05). In analysis of immunologic gene sets, high MMP-11 expression was related to low immune response such as CD8+T cell, CD4+T cell and B cell. In silico cytometry, there was a decrease of cancer testis antigen and low tumor infiltrating lymphocyte in patient with high MMP-11 expression: activated dendritic cell, CD8+T cell, CD4+ memory T cell, and memory B cell. In pathway networks, MMP-11 was linked to the pathways including low immune response, response to growth hormone and catabolic process. We found that pictilisib and AZ960 effectively inhibited the breast cancer cell lines with high MMP-11 expression. Strategies making use of MMP-11-related hub genes could contribute to better clinical management/research for patients with breast cancer.
