NanoString Highlights Record Number of nCounter-Related Research Abstracts Showcasing Advances in Precision Oncology at the 53rd Annual Meeting of the American Society of Clinical Oncology (ASCO)

More than 35 Abstracts Demonstrate the Value of the nCounter Platform for Targeted Discovery, Biomarker Development and Diagnostic Applications in Cancer Research and Immuno-Oncology

NanoString's New Digital Spatial Profiling Technology Featured in Two Abstracts

SEATTLE, May 25, 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 precision oncology and cancer immunotherapy using the nCounter® platform that will be presented at the 53rd Annual Meeting of the American Society of Clinical Oncology (ASCO). 

"The breadth of nCounter-based research at this year's ASCO conference demonstrates the scientific momentum and significant commercial advances that we've made in our key markets, most notably immuno-oncology," said Brad Gray, president and chief executive officer of NanoString. "In addition, our new Digital Spatial Profiling technology continues to demonstrate its unique value in characterizing the tumor microenvironment to inform decisions in drug development programs."

More than 35 abstracts will be presented at the ASCO Annual Meeting, which is being held June 2nd through June 6th, 2017 in Chicago, Illinois. The research being presented spans a wide breadth of applications including Targeted Discovery, Biomarker Development and Clinical Practice across multiple oncology indications, including the following.

Targeted Discovery
Multidimensional spatial characterization of the tumor microenvironment (TME) in synchronous melanoma metastases (SMM) to yield insights into mixed responses to therapy in metastatic melanoma (MM) patients (pts). (Abstract # 9575)
NanoString's new Digital Spatial Profiling research platform was used for spatial characterization of 30 immune markers and signaling proteins in melanoma patient samples to understand correlations and determinants of response.

Molecular characterization of immune-related severe adverse events (irSAE). (Abstract #3076)
NanoString Digital Spatial Profiling was used to profile the immune cell population in tissue affected by immune checkpoint inhibitors-mediated inflammation. Similarities and differences between autoimmune disease and colon-irSAEs were identified at the gene expression and proteomic levels, as regions of inflammation showed higher CD68 and PD-L1 positivity in colon-irSAE specimens versus normal colon or Crohn's specimens, and reduced beta-catenin levels in both Crohn's and colon-irSAE specimens relative to normal controls.

Distinct gene expression, mutational profile and clinical outcomes of V600E and V600K/R BRAF-mutant metastatic melanoma (MM). (Abstract #9541)
Gene expression and mutational profiling were used to investigate potential mechanisms explaining the observation that V600K/R metastatic melanoma has inferior response and shorter survival with MAPKi than V600E.

Biomarker Development
Correlation of constitutive PD-1 resistance in HNC with GM-CSF expression and presence of myeloid derived suppressor cells (MDSCs). (Abstract #6049)
A 638-gene immune gene expression panel was used to explore why the majority of INF-G inflamed head and neck squamous cell carcinomas (HNC) tumors do not respond to PD-1 checkpoint blockade. Constitutive resistance to PD-1 checkpoint blockade in inflamed HNC associates with expression of GM-CSF and Myeloid Derived Suppressor Cell (MDSC) markers. Strategies to deplete MDSCs, such as chemotherapy, should be considered in combination or sequentially with anti-PD-1.

Cellular immune biomarkers to prognosticate for survival to adoptive T-cell therapy in advanced nasopharyngeal cancer. (Abstract #6047)
nCounter platform and reagents were used for longitudinal modular transcriptome analysis  of PBMC from patients with stage 4c nasopharyngeal carcinoma who received first line chemo-immunotherapy with the aim of identifying signatures associated with positive clinical outcomes.
Results from this study showed that 2-year survivors displayed significant decreased amounts of monocytic myeloid-derived suppressor cells (mMDSCs), compared to non-survivors.  

Phase II study of durvalumab (anti-PD-L1 antibody) in combination with R-CHOP or lenalidomide plus R-CHOP in previously untreated, high-risk diffuse large B-cell lymphoma. (Abstract # TPS7573)
NanoString's Lymphoma Subtyping Test is being used to determine Cell of Origin in an ongoing clinical trial.  The primary study objective is to explore the clinical activity of durvalumab with R-CHOP in non-activated B-cell-like (non-ABC) and durvalumab with lenalidomide + R-CHOP (R2-CHOP) in ABC previously untreated DLBCL; secondary objectives are to evaluate safety and identify biomarkers predictive of clinical response.

Association of molecular subtype, proliferation, and immune genes with efficacy of carboplatin versus gemcitabine addition to taxane-based, anthracycline-free neoadjuvant chemotherapy in early triple-negative breast cancer (TNBC): Results of the randomized WSG ADAPT-TN trial. (Abstract #573)
NanoString assays combining the PAM50 breast cancer assay and immune profiling were used to characterize patients in a clinical trial.  In early TNBC, basal-like subtype, higher Ki67 (by IHC), and lower HER-2 score were associated with chemo-sensitivity for both neoadjuvant arms. Chemo-resistance pathways differed between the two taxane-based combinations. The positive predictive impact of immunological genes in the nab-pac - carbo arm could influence optimal patient selection for immune-modulative therapy.

Impact of consensus molecular subtyping (CMS) on overall survival (OS) and progression free survival (PFS) in patients (pts) with metastatic colorectal cancer (mCRC): Analysis of CALGB/SWOG 80405 (Alliance). (Abstract #3511)

CALGB 80405 was a randomized Ph3 trial showing no OS or PFS difference in mCRC pts treated with Bevacizumab (Bev) or Cetuximab (Cet) in the first line. A Nanostring platform was used to determine the CMS classification of 392 KRAS wt (codon 12 and 13) primary tumors and correlated it with OS and PFS in patients enrolled in 80405. Data suggest that CMS is associated with OS and PFS in first line therapy in mCRC patients. Preliminary data suggest that certain CMS may be associated with efficacy of Bev and Cet based chemotherapy.

Clinical Practice
Impact of the Prosigna (PAM50) assay on adjuvant clinical decision making in patients with early stage breast cancer: Results of a prospective multicenter public program. (Abstract # e12062)

In this prospective decision impact study, Prosigna results led to a 39% change in adjuvant therapy indication. Patients with initial indication of CHT were changed to HT alone in > 50% of cases. Thus, Prosigna results influenced the treatment decisions and reinforced its clinical utility in real-world settings. The intrinsic subtype classification based on IHC didn't show to be an adequate surrogate for the genomic subtypes as determined by Prosigna.

At the 2017 ASCO Annual Meeting, NanoString will showcase its nCounter platform, Digital Spatial Profiling and 3D Biology capabilities at booth #20097.
