Validated High Sensitivity ICE COLD-PCR™ Assay Uses Blood, Serum or Tissue Sample to Detect Important Predictor of Resistance to Third-Generation Kinase Therapies in NSCLC Patients

Rapid Assay Development in Response to Customer Demand Highlights Speed and Versatility of Transgenomic’s ICP Technology-Based Biomarker Discovery Services Group

OMAHA, Neb. (March 18, 2016) — Transgenomic, Inc. (NASDAQ: TBIO) today announced the launch of its EGFR C797S Mutation Detection Assay based on the company’s ICE COLD-PCR™ (ICP) technology. This new test detects the presence of the EGFR C797S mutation that is associated with resistance to new third-generation tyrosine kinase inhibitor (TKI) therapies in development for non-small cell lung cancer (NSCLC), one of the most common and deadly cancers in the US. The ultra-high sensitivity of Transgenomic’s ICP technology makes it possible to run the new assay using either tissue, blood or serum samples. The test is currently available for research use through Transgenomic’s Biomarker Discovery Services group and is expected to be available for clinical use through the company’s Oncology CLIA laboratory in Omaha, Nebraska later this year.

Transgenomic President and CEO Paul Kinnon commented, “Our rapid introduction of this important assay is an excellent example of our team’s ability to quickly produce ICE COLD-PCR based tests in response to the need for biomarkers relevant to the many new targeted cancer therapies being developed by pharmaceutical and biotechnology companies.”

Mr. Kinnon continued, “The EGFR C797S mutation is an important predictor of resistance in third-generation TKI therapies for NSCLC and requires a very high sensitivity assay for early detection of possible resistance using the blood or serum samples that are the only option available during ongoing treatment. Our ICP technology is an ideal solution–it has very high sensitivity and can be analyzed using any of the latest sequencing platforms. In addition, ICP also detects unknown (non-allele specific) mutations so that new prognostic markers can be identified in the course of testing.”

While the new assay detects EGFR mutation C797S, Transgenomic also has an assay for the EGFR T790M mutation, a known marker for resistance in first generation TKI therapies. This assay enriches for mutations in codon 790 and its immediately adjacent codons, while the new assay enriches for mutations in codon 797 and its immediately adjacent codons.

ICE COLD-PCR achieves its ultra-high sensitivity through selective amplification of mutant DNA. The result is up to a 500-fold increase in sensitivity in identifying mutations with the most precise sequence alteration detection rates available. ICP was originally developed by the laboratory of Dr. Mike Makrigiorgos at the Dana-Farber Cancer Institute, which has exclusively licensed rights to the technology to Transgenomic.
