Response Genetics, Inc. To Offer Enhanced ALK Testing Program For Metastatic Lung Cancer Patients

Response Genetics, Inc. (NASDAQ:RGDX), a company focused on the development and sale of molecular diagnostic tests for cancer, today announced a new anaplastic lymphoma kinase (ALK) testing program aimed to provide clinicians a more complete picture of the ALK rearrangement status of their non-small-cell lung cancer (NSCLC) patients. The company will include its PCR-based EML4-ALK test results for patients testing negative for the ALK Break Apart fluorescence in situ hybridization (FISH) test at minimal cost.

Approximately 3 to 5 percent of NSCLC tumors have a rearrangement of the ALK gene. In addition to providing the ALK Break Apart FISH assay, which has been clinically validated to predict response to the targeted therapy XALKORI® (crizotinib), Response Genetics has a proprietary EML4-ALK RT-PCR-based assay that detects rearrangements of the ALK gene. The Response Genetics PCR test has identified ALK variants in a subpopulation of cases that are negative by FISH, and that may respond to XALKORI® treatment. Samples that test negative for ALK FISH at Response Genetics will be further tested with the Company’s proprietary ALK PCR test.

“The number of additional patients that may be identified by further testing could be small, yet the value a positive test result can bring to even one more patient is immeasurable. We are pleased to make our proprietary ALK PCR test available, at minimal cost, to pathologists and oncologists. Our goal is to provide them with actionable information they need to give every potential patient the chance to respond to effective treatment for non-small-cell lung cancer,” said Thomas Bologna, chairman and CEO of Response Genetics. “By providing both ALK FISH and ALK RT PCR testing services cost-effectively, we believe we are enabling clinicians to make more informed treatment decisions for their patients.”
