NanoString Technologies and Cancer Immunotherapy Trials Network (CITN) Enter Into a Collaboration to Identify Biomarker Assays for Novel Cancer Immunotherapies

SEATTLE, May 5, 2015 (GLOBE NEWSWIRE) -- The Cancer Immunotherapy Trials Network (CITN) and NanoString Technologies, Inc. (Nasdaq:NSTG), a provider of life science tools for translational research and molecular diagnostic products, today announced a multi-year translational research collaboration to discover biomarkers that predict clinical outcomes for cancer immunotherapies, both as single agents and in combination. The collaboration will involve the systematic use of NanoString's nCounter® Analysis System and PanCancer Immune Profiling technology in multiple prospective CITN clinical trials.

"Our collaboration with NanoString focuses on a critical challenge in fully realizing the promise of cancer immunotherapy—finding biomarkers that will identify the patients most likely to benefit from treatment," said Martin "Mac" Cheever, M.D., Director of the CITN and researcher at Fred Hutchinson Cancer Research Center. "We expect this to become an even greater challenge as we explore potential combinations of these agents. Powerful tools for genomic and proteomic analysis are expected to play an important role in solving these puzzles."

Under the collaboration, NanoString's immuno-oncology targeted panels will be used to analyze blood and tissue biopsies at multiple time-points during immunotherapy clinical trials. The collaboration is intended to cover translational research initially using the PanCancer Immune Profiling Panel, which probes the expression of 770 genes, including genes for the identification of different immune cell types, cancer antigens, checkpoint blockades, and both innate adaptive and humoral immune responses. The collaboration may be expanded in the future to include NanoString's RNA:Protein technology, which enables simultaneous profiling of both gene and protein expression, including 30 proteins important in immuno-oncology research, including PD-1, PD-L1 and CTLA4.

"NanoString's nCounter technology is ideally suited to answering complex biological questions like those facing researchers in the field of immuno-oncology," stated Joseph Beechem, Ph.D., Senior Vice President of Research and Development at NanoString Technologies. "Our ability to simultaneously measure the expression of up to 800 genes and proteins associated with the immune system's response to cancer provides a wealth of information, while preserving precious tumor samples to facilitate many additional experiments."

Initially, the collaboration will be focused on malignant melanoma and epithelial ovarian, Fallopian tube, and primary peritoneal carcinomas treated with novel cancer immunotherapies, and additional clinical trials and indications may be added as the collaboration progresses. Under the terms of the agreement, NanoString is granted rights to research and diagnostic content developed within the scope of the collaboration.
