Landmark Publications in Nature Medicine use NanoString’s Digital Spatial Profiling Platform to Discover Novel Insights in Immuno-Oncology
Two Independent Studies Use the GeoMx Digital Spatial Profiler to Investigate the Role of the Tumor and Micro-environment in Immunotherapy Response
SEATTLE, Oct. 08, 2018 (GLOBE NEWSWIRE) -- NanoString Technologies, Inc. (NASDAQ:NSTG), a provider of life science tools for translational research and molecular diagnostic products, today announced that the first peer-reviewed publications using the GeoMx™ Digital Spatial Profiler have been published in the journal Nature Medicine. Two independent papers describe the use of Digital Spatial Profiling (DSP) technology to identify biomarkers correlating with response to neoadjuvant therapy in patients with high-risk melanoma.
The GeoMx Digital Spatial Profiler was used to characterize pretreatment tumor biopsies and revealed differential expression of several potential biomarkers, including B2M and CD3. The first publication was led by researchers at the DSP Center of Excellence at the Netherland Cancer Institute and entitled “Neoadjuvant versus adjuvant ipilimumab plus nivolumab in macroscopic stage III melanoma” ( https://www.nature.com/articles/s41591-018-0198-0 ).
“We used the DSP platform to characterize pretreatment tumor biopsies to understand how the preexisting immune status of the melanoma biopsies predicts response,” said Christian Blank, M.D., Group Leader of Immunology at the Netherlands Cancer Institute. “The high plex capabilities of DSP technology enabled us to interrogate many more potential biomarkers than would have been possible on these very small tissue biopsies with standard or multiplexed IHC approaches.”
The second study, entitled “Neoadjuvant immune checkpoint blockade in high-risk resectable melanoma,” was led by Dr. Jennifer Wargo, M.D., M.M.Sc. and Dr. Michael Tetzlaff, M.D., Ph.D. of the MD Anderson Cancer Center ( https://www.nature.com/articles/s41591-018-0197-1 ).
“In this study, we were interested in characterizing predictors of response to neoadjuvant nivolumab or nivolumab and ipilimumab. DSP technology enabled us to quantify protein expression specifically in tumor infiltrating immune cells in both pre-treatment and on-treatment biopsy specimens—many of which were small needle core biopsy specimens with a limited number of tumor and/or immune cells,” said Dr. Jennifer Wargo. “With DSP technology we were able to discover that both presence of particular immune cell populations and their activation status may be predictive of clinical benefit to this therapy.”
“Each of these studies independently demonstrates the value of the Digital Spatial Profiling approach in identifying potential biomarkers that may guide patient management in terms of therapeutic strategy and follow up,” said Alessandra Cesano, M.D., Ph.D., NanoString’s chief medical officer. “I look forward to these publications being the first of many that will address previously unanswered questions both from mechanistic as well as clinical perspectives in the field of immuno-oncology using this novel, multi-plexed molecular profiling approach to spatially dissect tumors.”
The data for both publications was generated as part of the DSP Technology Access Program, under which samples are processed at NanoString using prototype GeoMx Digital Spatial Profilers.
The GeoMx Digital Spatial Profiler enables researchers to rapidly and quantitatively characterize tissue morphology with a high-throughput, high-plex RNA and protein profiling system that preserves precious samples for future analyses. NanoString and its collaborators have presented DSP data in more than a dozen abstracts at major scientific meetings, demonstrating the utility of DSP technology to address a wide range of biological questions in Formalin Fixed Paraffin Embedded (FFPE) tissues.
NanoString recently announced the GeoMx™ Priority Site (GPS) program which offers customers the opportunity to be among the first to receive a GeoMx instrument following its expected commercial launch in the first half of 2019, as well as advanced service and support. Inclusion in the GPS Program will also provide researchers the opportunity to begin generating data on their samples through the Technology Access Program in advance of receiving their GeoMx instrument. GPS status will be limited to the first 20 participants who purchase the commercial system.
