Response Genetics Launches National Sales Strategy for Its ResponseDX(TM) Tests Through Exclusive Agreement With NeoGenomics Laboratories and Formation of Sales Team

In addition to Response Genetics offering its ResponseDX(TM) tests through its own newly formed specialized sales team, and under the terms of the agreement, NeoGenomics will be the exclusive national clinical reference laboratory authorized to offer Response Genetics' proprietary tests through their own proven national sales force. All tests will be performed through Response Genetics' CLIA-certified laboratory.

"We are extremely pleased to be working with NeoGenomics to expand the availability of our ResponseDX(TM) tests to the national marketplace," said Kathleen Danenberg, Response Genetics' President and CEO. "Through the strength of the two companies' sales forces, we will work together to introduce Response Genetics' proprietary technologies to help make personalized medicine a reality for cancer patients."

"Most agree that the future of clinical laboratory testing continues to move towards genomics-based technologies, such as those being pioneered by Response Genetics," said Robert P. Gasparini, NeoGenomics' President and Chief Scientific Officer. "We could not be more pleased than to have Response Genetics as a partner in this endeavor. We believe this combination of two leaders in molecular diagnostics will allow us to establish new accounts, differentiate our services, and increase our footprint in the expanding field of molecular cancer genetics."

About ResponseDX Tests

Response Genetics developed PCR-based genetics tests-ResponseDX: Lung(TM) and ResponseDX: Colon(TM)-to help physicians with therapeutic treatment decisions in patients with non-small cell lung cancer (NSCLC) and colorectal cancer (CRC). The proprietary ResponseDX panels include three key genes: ERCC1, TS and EGFR. These tests also include the analysis of K-ras gene (KRAS) mutations, which is a strong predictor of non-response and no benefit from the epidermal growth factor receptor (EGFR) inhibitors. Response Genetics KRAS mutation analysis provides one of the fastest turn around times in the industry and accurate results on the smallest biopsies. The benefit for patients is that in many cases, no tissue samples other than the pre-treatment diagnostic biopsy will be required for the biomarker analysis. Using ResponseDX testing, clinicians may make better treatment decisions via a cost-effective panel approach utilizing additional genes beyond KRAS.
