LOS ANGELES, June 4, 2013 (GLOBE NEWSWIRE) -- Response Genetics, Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests that help determine a patient's response to cancer therapy, today announced that it has achieved its second milestone payment in conjunction with the non-exclusive license agreement originated in 2010 with GlaxoSmithKline ("GSK").

Under the terms of the agreement, GSK gained certain rights to Response Genetics' proprietary PCR analysis technology and diagnostic expertise to assess BRAF gene mutations in human tumor samples. Response Genetics earned its first milestone payment of $500,000 in July of 2012 for submission of the first Premarket Approval ("PMA") under the contract. On May 29, 2013, GSK announced the FDA's approval of the PMA, thereby triggering the second milestone payment of $500,000.

The BRAF gene is responsible for a protein involved in cell signaling, growth and differentiation. Specific mutations in the gene are found in a subset of patients with melanoma.Tafinlar® has been approved to treat melanoma that cannot be surgically removed or metastatic melanoma in adults with the V600E mutation of BRAF. Tafinlar® is not indicated for patients with wild-type BRAF melanoma.

"We are extremely pleased to have assisted GSK in achieving this very important milestone," said Thomas A. Bologna, Chairman and CEO of Response Genetics. "Response Genetics supports pharmaceutical companies by providing lab-developed tests that are critical for screening and stratifying patients during clinical development. The insights that emerge from our work, such as the association between the specific mutations of BRAF and response to Tafinlar®, enable the practice of precision medicine, the selection of a cancer treatment based on the molecular characteristics of a patient's tumor."
