SEATTLE, Dec. 05, 2016 (GLOBE NEWSWIRE) -- NanoString Technologies, Inc. (NASDAQ:NSTG), a provider of life science tools for translational research and molecular diagnostic products, today announced advances in precision oncology using the Prosigna® Breast Cancer Gene Signature Assay and the PAM50 gene signature, the basis for Prosigna, will be presented at the 2016 CTRC-AACR San Antonio Breast Cancer Symposium (SABCS). In addition, numerous customers will be presenting data generated using NanoString’s nCounter® Analysis System, including several involving immuno-oncology.
"The volume and impact of the clinical research being presented at the SABCS underscores our commitment to improving the lives of breast cancer patients," said Brad Gray, president and chief executive officer of NanoString Technologies. “These studies demonstrate that our Prosigna Assay can improve decision-making in early-stage breast cancer today, and that a modified companion diagnostic version of this assay has future potential in triple negative breast cancer. The studies also show that our nCounter Analysis System is continuing to grow in prominence as an important tool among breast cancer researchers.”
NanoString and its collaborators will present three oral presentations and fourteen posters covering Prosigna/PAM50 and other nCounter-based research at SABCS, which is being held December 6-10, 2016.
Following are details for each presentation of data involving Prosigna and the PAM50 gene signature (all times are in Central Standard Time):

About the Prosigna® Breast Cancer Prognostic Gene Signature Assay and nCounter® Dx Analysis System
The Prosigna Assay provides a risk category and numerical score for assessment of the risk of distant recurrence of disease at 10 years in postmenopausal women with node-negative (Stage I or II) or node-positive (Stage II), hormone receptor-positive (HR+) breast cancer. Based on the PAM50 gene signature initially discovered by Charles Perou, Ph.D. and colleagues, the Prosigna Assay is an in vitro diagnostic tool that utilizes gene expression data weighted together with clinical variables to generate a risk category and numerical score to assess a patient's risk of distant recurrence of disease. The Prosigna Assay measures gene expression levels of RNA extracted from formalin-fixed paraffin embedded (FFPE) breast tumor tissue previously diagnosed as invasive breast carcinoma.
The Prosigna Assay requires minimal hands-on time and runs on NanoString's proprietary nCounter® Dx Analysis System, which offers a reproducible and cost-effective way to profile many genes simultaneously with high sensitivity and precision.
The nCounter Dx Analysis System is a highly automated and easy-to-use platform that utilizes a novel digital barcoding chemistry to deliver high precision multiplexed assays. The system is available in the multi-mode FLEX configuration, which is designed to meet the needs of high-complexity clinical laboratories seeking a single platform with the flexibility to run the Prosigna Breast Cancer Assay and, when operated in the "Life Sciences" mode, process translational research experiments and multiplexed assays developed by the laboratory.
In the United States, the Prosigna Assay is 510(k) cleared for use on the nCounter Dx Analysis System, and is available for diagnostic use when ordered by a physician. The Prosigna Assay has been CE-marked and is available for use by healthcare professionals in the European Union and other countries that recognize the CE Mark, as well as Canada, Israel, Australia, New Zealand, Argentina, Thailand, South Africa, Turkey and Hong Kong. In the U.S., the Prosigna Assay is indicated in female breast cancer patients who have undergone surgery in conjunction with locoregional treatment consistent with standard of care, either as:
(1) a prognostic indicator for distant recurrence-free survival at 10 years in postmenopausal women with Hormone Receptor-Positive (HR+), lymph node-negative, Stage I or II breast cancer to be treated with adjuvant endocrine therapy alone, when used in conjunction with other clinicopathological factors or (2) a prognostic indicator for distant recurrence-free survival at 10 years in postmenopausal women with Hormone Receptor-Positive (HR+), lymph node-positive (1-3 nodes), Stage II breast cancer to be treated with adjuvant endocrine therapy alone, when used in conjunction with other clinicopathological factors. The device is not intended for patients with four or more positive nodes.
Other uses of Prosigna or the PAM50 panel in studies as described in this press release are for Investigational Use Only, or Research Use Only.
