Presentations Include Data from More than Thirty NanoString-Related Abstracts Including Five Using the GeoMx Digital Spatial Profiler

NanoString Technologies, Inc. (NASDAQ:NSTG), a leading provider of life science tools for translational research and molecular diagnostic products, today announced the highlights of numerous abstracts demonstrating advances in understanding of immune response and cancer immunotherapy using the nCounter® and GeoMx™ Digital Spatial Profiler (DSP) platforms that will be presented at the 34th Annual Meeting of the Society of Immunotherapy for Cancer (SITC).

“Immunotherapy represents one of the most exciting fields for developing breakthrough treatments for cancer,” said Brad Gray, president and CEO of NanoString. “We are honored to see the continuing contribution that our nCounter and GeoMx DSP technologies are making toward understanding the mechanism of cancers and the critical role that the immune system plays in predicting patient response.”

More than 30 abstracts using NanoString’s nCounter and GeoMx DSP platforms will be presented at the SITC Annual Meeting, being held Nov. 7–10, 2019, at the Gaylord National Hotel & Convention Center in National Harbor, Md. The research being presented spans a wide breadth of applications, including biomarker development, the study of immune responsiveness and resistance, and digital pathology.

Five studies include the use of NanoString’s GeoMx DSP platform in immuno-oncology research. These abstracts include numbers P3, P24, P30, P126 and P305 that are described below. GeoMx DSP allows for digital quantification of protein and gene expression from discrete regions of FFPE tissue in an automated and multiplex format.

NanoString is currently accepting applications for its Technology Access Program (TAP). To inquire, please e-mail TAP@nanostring.com.

Title: Deep Spatial Profiling of the Immune Landscape of MSI and MSS Colorectal Tumors

Authors: Sarah E. Church, PhD; Jason W. Reeves; Daniel R. Zollinger; Jill McKay-Fleisch; Andrew M. White, BSc; Michael D. Bailey; Arya Bahrami, PhD; Chris Merritt, PhD; Margaret Hoang; Sarah Warren, PhD; Joseph M. Beechem, PhD

Summary: Colorectal tumors that were characterized as Microsatellite Stable (MSS) or Microsatellite Instable (MSI) were profiled using IO360 and GeoMx DSP. 60 samples were run on IO360 for bulk gene expression profiling and then profiled using the tumor inflammation signature (TIS) scores, along with MSI status to identify immune hot and cold tumors for further profiling with GeoMx DSP using the new Cancer Transcriptome Atlas assay.

Title: Discovery of biomarkers associated with benefit from PD-1 checkpoint blockade in non-small-cell lung cancer (NSCLC) using high-plex digital spatial profiling

Authors: Jon Zugazagoitia, MD, PhD, Yale University School of Medicine, Pathology, Jon Zugazagoitia, MD, Swati Gupta, PhD, Kit Fuhrman, MS PhD, Scott N. Gettinger, MD, Roy S. Herbst, MD, PhD, Kurt A. Schalper, MD, PhD, David L. Rimm, MD, PhD

Summary: Digital Spatial Profiling (DSP) technology identifies spatially-resolved protein markers associated with outcome from single-agent PD-1 checkpoint blockade in NSCLC. High levels of CD56 (top tertile) and CD4 (median) measured in the CD45 compartment were the only markers that were predictive for all clinical outcomes, including longer PFS.

Title: Response to Pembrolizumab and tumor microenvironment composition is associated with IL8 expression in a head and neck squamous-cell carcinoma cohort

Authors: Arun Khattri, PhD; Jason W. Reeves; SuFey Ong; Riyue Bao, PhD; Arya Bahrami, PhD; Yi-Hung Carol Tan, PhD; Andrew M. White, BSc; Michael P. Bailey; Heather A. Brauer, PhD; Sarah Warren, PhD; Joseph M. Beechem, PhD; Tanguy Seiwert, MD

Summary: More than 100 head and neck cancer samples were profiled using IO360. There was a modest association between tumor inflammation signature (TIS) and response. There was also a modest association between IL8 expression and progressive disease (PD) status. Follow-up analysis with GeoMx DSP used ISH staining to guide the selection of IL8+ and IL8- ROIs.

At the 2019 SITC Annual Meeting, NanoString will showcase its nCounter platform, IO360 and Data Analysis and GeoMx Digital Spatial Profiler at booth #511.
