OMAHA, Neb. — Transgenomic, Inc. (OTCBB: TBIO) today announced the global, commercial availability of CRC RAScan™, a new mutation detection test to screen patients with metastatic colorectal cancer (mCRC) for RAS mutations (KRAS and NRAS). These RAS mutations, identified using the CRC RAScan™ kits which use Surveyor®-Wave® technology, provide physicians with important information regarding tumor mutation status to help with clinical treatment decisions for their mCRC patients. Transgenomic’s CLIA-certified laboratory in the United States (U.S.) is available immediately to receive patient samples for testing. In Europe, CE-IVD registered test kits are available for purchase. Research-only test kits will soon be available for purchase in the U.S.

The CRC RAScan™ kit was developed in collaboration with Amgen Inc. (NASDAQ: AMGN), and follows discovery of RAS (KRAS and NRAS) mutations in a predefined-retrospective subset analysis of a global, multicenter, randomized Phase 3 study. Results of this analysis will be presented at the 2013 ASCO Annual Meeting on June 4 (Abstract Number 3511; 8:00 a.m. – 12:00 p.m. CDT, S405).

“Our partnership with Amgen, and development of CRC RAScan, supports our goal of developing predictive tests that can help physicians make decisions when selecting treatment options for patients” said Craig Tuttle, Chief Executive Officer of Transgenomic. “CRC RAScan is the only dedicated test available today that identifies the full range of RAS mutations to help with treatment decisions for patients with metastatic colorectal cancer.”

About CRC RAScan

CRC RAScan utilizes the DNA mismatch-cutting enzyme SURVEYOR Nuclease, developed exclusively by Transgenomic. This enzyme recognizes nucleotide mismatches in a mixture of wild-type and mutant DNAs reflective of what is found in tumor biopsy samples. The enzyme cleaves at the site of the mismatch; cleavage products can be very simply detected and are indicative of the presence of a potential mutation in a target DNA sequence. Sanger sequencing can subsequently identify the detected base change in gene regions covered by the CRC RAScan test. The SURVEYOR Nuclease assay, which is more sensitive for mutation detection than stand-alone Sanger sequencing, can be used to help resolve marginal and low level sequencing results. Therefore, the CRC RAScan test provides increased sensitivity for the detection of mutations at relevant levels for optimal therapy selection. Additionally, in gene regions where mutations exist at low frequencies, prescreening with CRC RAScan affords a cost and time-efficient workflow, as only CRC RAScan positive samples are advanced to the more complex and expensive Sanger sequencing analysis.

About Colorectal Cancer

Colorectal cancer is the fourth most common cancer diagnosed in men and in women in the United States. The American Cancer Society estimated that about 102,480 new cases of colon cancer and 40,340 new cases of rectal cancer will be diagnosed in 2013. Colorectal cancer is the second most frequent cause of cancer death among men and women in the United States. It has been estimated that 50,830 people will die from colorectal cancer in 2013.

More About RAS Mutations

KRAS and NRAS are part of the RAS family of genes that encodes proteins involved in transmitting signals within cells. When RAS proteins are “switched on” by incoming signals, other genes involved in cell growth, differentiation and survival are activated. Mutations in KRAS, NRAS and other related genes can lead to RAS-encoded proteins becoming permanently activated, causing overactive signaling even in the absence of incoming signals, and can lead to the uncontrolled cell growth that characterizes cancer. Mutations that permanently activate RAS-encoded proteins are found in approximately 25% of human tumors and up to 90% of certain cancers. About 40% of colorectal tumors carry KRAS gene mutations and these mutations have been associated with poor response to EGFR antagonists.
