LOS ANGELES, March 10, 2014 (GLOBE NEWSWIRE) -- Response Genetics, Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests for cancer today announced the commercial availability of its expanded KRAS assay, a mutation detection test that provides broader coverage of KRAS mutations, including those in regions of the gene not previously examined.

KRAS mutation status is used to predict whether or not a patient will respond to anti-EGFR therapy, and assessing KRAS status is recommended in the NCCN guidelines for colorectal cancer. Recently, additional mutations in the KRAS gene were discovered in global, multicenter, randomized Phase 3 studies.1,2 These studies showed that in addition to the well-studied mutations in exon 2 that predict for lack of response to anti-EGFR therapy, mutations in exon 3 and exon 4 may be important for anti-EGFR therapy selection.

"As a company known for its first-to-market innovation, we are pleased to introduce a test that detects more mutations in a gene not examined previously, allowing for a more thorough and comprehensive screening of colorectal cancer," said Thomas A. Bologna, Chairman and Chief Executive Officer of Response Genetics. "Identifying a broader range of KRAS mutations increases the potential for more targeted and appropriate treatment of colorectal cancer patients."
