Abstract

Responders to checkpoint blockade in Non Small Cell Lung Cancer (NSCLC) often feature an inflamed microenvironment prior to therapy. However, the complete set of molecular drivers connecting this histologic observation to enhanced tumor clearance remain enigmatic. In updated analysis of the Stand Up 2 Cancer-Mark Foundation (SU2C-MARK) Cohort - a collection of 393 patients with whole exome and/or RNA sequencing along with matched checkpoint blockade response annotation - we identify a prominent predictive role for inducible components of the immunoproteasome, a non-canonical peptide processing complex upstream of antigen presentation. Notably, these subunits are enriched as predictors relative to interferon-inducible genes as well as proteasome components in general, and are consistently associated with objective response, progression-free survival and overall survival. Expression of Immunoproteasome subunits associates positively with TCR (but not BCR) burden, supporting a mechanistic model in which enhanced immunoproteasome processivity leads to superior T-cell recognition. Furthermore, although they are known to be targets of interferon gamma (IFNɣ), we demonstrate that their expression is better modeled via a combination of IFNɣ and tumor necrosis factor-α (TNFα) levels, suggesting they may act as integrators of multiple cytokine cascades. Given the fact that the immunoproteasome can alter both antigen quantity as well as quality (including peptide cleavage site preference), the enhanced expression of this complex in the setting of checkpoint blockade response may have important implications for modeling of antigen presentation. These data also suggest novel strategies to enhance immune checkpoint blockade.

Abstract

Academic, industry, regulatory leaders and patient advocates in cancer clinical research met in November 2018 at the Innovation and Biomarkers in Cancer Drug Development meeting in Brussels to address the existing dichotomy between increasing calls for personalised oncology approaches based on individual molecular profiles and the need to make resource and regulatory decisions at the societal level in differing health-care delivery systems around the globe. Novel clinical trial designs, the utility and limitations of real-world evidence (RWE) and emerging technologies for profiling patient tumours and tumour-derived DNA in plasma were discussed. While randomised clinical trials remain the gold standard approach to defining clinical utility of local and systemic therapeutic interventions, the broader adoption of comprehensive tumour profiling and novel trial designs coupled with RWE may allow patient and physician autonomy to be appropriately balanced with broader assessments of safety and overall societal benefit.

Abstract

The introduction of checkpoint blockade therapy, specifically anti-PD-1/PD-L1 agents, has transformed the treatment landscape of advanced Non-Small Cell Lung Cancer (NSCLC). While our understanding of the biology underlying immunotherapy in NSCLC is still incomplete, studies to date have established central roles for Tumor Mutation Burden (TMB) and PD-L1 Tumor Proportion Score (PDL1-TPS). In order to expand our understanding of the molecular features underlying response in NSCLC, we describe here the first joint analysis of the Stand Up 2 Cancer-Mark Foundation (SU2C-MARK) Cohort, a collection of 393 patients with whole exome and/or RNA sequencing along with matched checkpoint blockade response annotation. We identify a number of significant associations between molecular features and response, including: 1) favorable and unfavorable genomic subgroups; 2) distinct immune infiltration signatures associated with wound healing (unfavorable) and immune activated (favorable) microenvironments; and 3) a novel de-differentiated tumor-intrinsic subtype characterized by high TMB, immune activation, and enhanced response rate. Taken together, results from this cohort extend our understanding of NSCLC-specific predictors, providing a rich set of molecular and immunologic hypotheses with which to further our understanding of the biology of checkpoint blockade in NSCLC.

Abstract

Introduction: DNA mutation analysis in individual patients paves the road towards personalized medicine, in which prognosis and therapy prediction are determined based on gene mutations. For example, it is known that RAS mutations are a negative predictor biomarker for response to therapeutic monoclonal antibodies directed against the epithelial growth factor receptor (EGFR) in metastasized colorectal cancer (mCRC) patients. Anti-EGFR treatment is expensive and 80-90% of the patients who do not benefit from anti-EGFR therapy suffer from the negative side-effects. Therefore, better prediction and monitoring of anti-EGFR treatment response is necessary. Cell-free circulating tumor DNA (ctDNA) derived from blood plasma is expected to improve stratification by early detection of therapy resistance and disease progression. Aim: The general aim of this study is to advance towards clinical implementation of ctDNA-based tests as molecular biomarkers to improve disease management of mCRC patients. In particular, we investigate the added value of liquid biopsy mutation analysis for (1) assessment of primary and acquired resistance to anti-EGFR treatment using a gene panel, compared to the conventional tissue analyses, and (2) for detection of disease progression, compared to conventional computed tomography (CT) imaging. Methods: CAIRO5 is a multicenter, randomized, phase 3 clinical trial of the Dutch Colorectal Cancer Group and includes patients with initially unresectable, liver-only mCRC, as confirmed by a central panel of liver surgeons/radiologists. Liquid biopsies are longitudinally collected in cell-save Streck tubes at baseline and during follow-up, in parallel with the CT imaging (every 2 to 3 months). In ctDNA, RAS/RAF hotspot mutations are analyzed by droplet digital PCR (ddPCR), while a panel of 33 genes will be analyzed using ultrasensitive next generation sequencing approaches. Results: The nation-wide multicenter logistics for longitudinal blood sample collection and plasma processing has been established, with participation of more than 55 Dutch hospitals. At present (November 2018), over 350 patients have been included from whom more than 850 blood samples were obtained. Based on tissue analyses, 59% of these patients harbors a RAS/RAF mutation (48% KRAS, 5% NRAS, 6% BRAF). Concordance between tissue biopsy and liquid biopsy was determined in a subset of patients and showed a >90% concordance for KRAS at codons 12, 13 or 61. In addition, radiologic evaluations of the CT images are collected and the lead time for recurrence will be compared with ctDNA analysis. Results of a first selection of patients will be presented. Conclusion: The liquid biopsy ctDNA and clinical data obtained in this study will provide the input for a health technology assessment yielding recommendations for clinical implementation of ctDNA applications.

Abstract

EGF receptor (EGFR)-targeted monoclonal antibodies are effective in a subset of metastatic colorectal cancers. Inevitably, all patients develop resistance, which occurs through emergence of KRAS mutations in approximately 50% of the cases. We show that amplification of the MET proto-oncogene is associated with acquired resistance in tumors that do not develop KRAS mutations during anti-EGFR therapy. Amplification of the MET locus was present in circulating tumor DNA before relapse was clinically evident. Functional studies show that MET activation confers resistance to anti-EGFR therapy both in vitro and in vivo. Notably, in patient-derived colorectal cancer xenografts, MET amplification correlated with resistance to EGFR blockade, which could be overcome by MET kinase inhibitors. These results highlight the role of MET in mediating primary and secondary resistance to anti-EGFR therapies in colorectal cancer and encourage the use of MET inhibitors in patients displaying resistance as a result of MET amplification. Significance: Amplification of the MET proto-oncogene is responsible for de novo and acquired resistance to anti-EGFR therapy in a subset of colorectal cancers. As multiple anti-MET therapeutic strategies are available, these findings offer immediate novel opportunities to design clinical studies. Cancer Discov; 3(6); 658–73. ©2013 AACR.
