LOS ANGELES, May 14, 2014 (GLOBE NEWSWIRE) -- Response Genetics, Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests that help guide cancer therapy selection, today announced execution of a commercial agreement with DxM Diagnostico Molecular ("DIFRA"), a leading distributor for cancer testing in Mexico, to offer the ResponseDX testing services to patients throughout Mexico.

The agreement covers the ResponseDX: Tissue of Origin test as well as the other targeted molecular tests in the Response Genetics portfolio. The ResponseDX: Tissue of Origin test is an FDA-cleared test that uses gene expression analysis to provide a definitive diagnosis for poorly-differentiated or metastatic cancers without a clear primary origin. The test was acquired by Response Genetics in August 2013 and re-introduced to the market in February 2014.

Cancer is currently the second leading cause of death in Mexico, with approximately 125,000 new cases each year and projections for doubling to 250,000 new cases per year by 2030.1 DIFRA will market the ResponseDX portfolio through presentations to hospitals and physician practices including presenting the ResponseDX: Tissue of Origin test to oncologists, physicians and key opinion leaders at the June 2014 Best of ASCO meeting in Mexico City.

"We believe the ResponseDX® offerings, including our new and recently introduced proprietary Tissue of Origin test provides differentiated content to effectively pursue international market opportunities" said Thomas Bologna, Chairman and Chief Executive Officer of Response Genetics. "One of our initiatives is to increase access to our testing services both domestically and internationally. DIFRA will facilitate access to the full complement of our portfolio to Mexican oncologists and pathologists. We believe our extensive molecularly-focused solid tumor menu coupled with high service levels and market-leading innovation will provide Mexico's cancer community with optimal options for the therapy-selection decision-making tools they seek."

The new agreement is the first in Central America for Response Genetics, as the company continues to expand its testing services including profiles for lung, colon, gastric, breast, and thyroid cancers and melanoma into international markets. The company is pursuing distribution agreements in Asia, Europe and the Middle East.
