NanoString Highlights Record Number of nCounter-Based Research Abstracts at the 2017 Annual Meeting of the Society of Immunotherapy of Cancer (SITC)

45 Abstracts Demonstrate the Value of the nCounter Platform for Immuno-Oncology Research

Studies Indicate the Clinical Relevance of the Tumor Inflammation Signature for Multiple Immunotherapies

SEATTLE, Nov. 09, 2017 (GLOBE NEWSWIRE) --  NanoString Technologies, Inc. (NASDAQ:NSTG), a provider of life science tools for translational research and molecular diagnostic products, today announced the highlights of numerous advances in understanding immune response and cancer immunotherapy using the nCounter® platform that will be presented at the 32nd Annual Meeting of the Society of Immunotherapy of Cancer (SITC).

"The scope of nCounter-based research being presented at this year's SITC conference demonstrates our scientific and commercial momentum in immuno-oncology," said Alessandra Cesano, chief medical officer of NanoString. "In addition, several abstracts outline the unique capabilities of our Digital Spatial Profiling technology to characterize the tumor and its microenvironment to inform cancer research and drug development."

At least 45 abstracts using NanoString's nCounter platform will be presented at the SITC Annual Meeting, being held in National Harbor, Maryland, Nov. 8-12, 2017. The research being presented spans a wide breadth of applications including biomarker development, assessing the biology of immune responsiveness and resistance, and digital pathology.  They include biomarker studies covering 21therapeutic agents, as single agents or in combination.

Nineteen studies used NanoString's PanCancer Series of panels to explore biomarkers associated with response to immunotherapy.  Fourteen of these studies incorporate NanoString's best-selling PanCancer Immune Profiling Panel.  An additional five studies incorporating both early access and commercial versions of NanoString's new PanCancer IO 360™ Panel.  The PanCancer IO 360 Panel assays key pathways from the tumor, the microenvironment and the immune system and includes more than 20 signatures that are potentially associated with therapeutic response to novel therapeutic agents with "matched" mechanisms of action.  Three additional studies incorporate the nCounter Hallmarks of Cancer suite of gene expression panels, which includes three panels covering Cancer Immune Profiling, Cancer Pathways, and Cancer Progression.

The PanCancer IO 360 Panel studies provide initial evidence of positive association between the Tumor Inflammation Signature scores and clinical response to different immuno-oncology agents including nivolumab, ipilimumab, pembrolizumab and entinostat. NanoString's Tumor Inflammation Signature (TIS) was recently described by Ayers, et al. ( and is included in the PanCancer IO360 panel. The Tumor Inflammation Signature measures the presence or absence of a peripherally suppressed adaptive immune response within the tumor.    

Five studies cover the use of NanoString's Digital Spatial Profiling (DSP) platform in immuno-oncology research.  DSP allows for digital quantification of protein from discrete regions of FFPE tissue in an automated and multiplex format.  DSP will become widely available with the launch of a new instrument planned for late 2018, and in the meantime is available under a Technology Access Program.

Two studies cover the use of 3D Biology™ panels and demonstrate the utility of the nCounter platform. NanoString's 3-D Flow™ technology provides detailed molecular profiles of T cell populations, and enables unique, simultaneous analysis of high-plex protein and RNA data.  3D Biology and 3D Flow approaches can be used to characterize baseline immunological state and response to stimulation, which may be useful for profiling mechanisms of action or therapeutic response.

At the 2017 SITC Annual Meeting, NanoString will showcase its nCounter platform, IO360 Data Analysis, Digital Spatial Profiling and 3D Biology capabilities at booth #605.

NanoString will host a Digital Spatial Profiling Educational Session on Nov. 11, 2017, 12:45 - 1:45 p.m.
