关键词： 安进 Transgenomic 结直肠癌 RAS检测
2013年5月8日讯 /生物谷BIOON/ --安进（Amgen）日前宣布，已与Transgenomic公司签署了一项合作协议，开发CE-IVD CRC RAScan突变检测试剂盒，用于转移性结直肠癌（mCRC）患者中RAS突变（KRAS及NRAS）的筛查。该试剂盒将成为首个能够更准确地检测重要KRAS及NRAS突变的CE-IVD试剂盒。
该试剂盒利用Surveyor-Wave技术鉴别出这些RAS突变，能够为临床医师提供有关肿瘤突变状态的重要信息，帮助确定其转移性结直肠癌患者的临床治疗决策。
有关CRC RAScan
CRC RAScan利用了Transgenomic公司专有分子技术开发的DNA错配切割酶SURVEYOR Nuclease，该酶能够识别肿瘤活检样本中野生型和突变型DNA混合物中的核酸错配，并在错配位点处切割，酶切产物能够非常简单地检测到，并能够指示出靶标DNA序列中的潜在突变。（生物谷bioon.com）

Transgenomic Signs Collaboration Agreement with Amgen for Development of CE-IVD CRC RAScan? Mutation
Transgenomic Signs Collaboration Agreement with Amgen for Development of CE-IVD CRC RAScan? Mutation Detection Tests for Patients with Metastatic Colorectal Cancer
First CE-IVD Test to More Accurately Detect Important KRAS and NRAS Mutations
OMAHA, Neb.--(BUSINESS WIRE)-- Transgenomic, Inc. (OTCBB: TBIO) today announced that it has entered into a collaboration with Amgen Inc. (NAS: AMGN) to develop a CE-IVD test to screen patients with metastatic colorectal cancer (mCRC) for RAS mutations (KRAS and NRAS). These RAS mutations, identified using the CE-IVD CRC RAScan? kits which use Surveyor?-Wave? technology, provide physicians with important information regarding tumor mutation status to inform clinical treatment decisions for their mCRC patients. Financial terms of the agreement were not disclosed.
"This collaboration with Amgen is indicative of how Transgenomic's proprietary molecular technologies are advancing personalized medicine," said Craig Tuttle, Chief Executive Officer of Transgenomic. "This highly precise, innovative test was developed at Transgenomic's laboratories, which excel in genomic and genetic analysis, novel technology development, and its application in clinical research and trials."
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 will be available for purchase shortly. Test kits will also soon be available for purchase in the U.S. (for research use only). For more information about how to obtain the CRC RAScan test or testing kits contact Transgenomic at (877) 274-9432 or by email at
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 assay test. The SURVEYOR Nuclease assay can detect mutations at higher levels of sensitivity than stand-alone Sanger sequencing. CRC RAScan results can also be used to inform marginal or difficult to resolve sequencing results. 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 third 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 third most frequent cause of cancer death among men and women in the United States and Canada. It has been estimated that 56,370 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-encodedproteins 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.
