FOXA1 biomarker predicts likelihood of recurrence and long-term disease-free survival of breast cancer patients; Further strengthens Company's breast cancer menu ALISO VIEJO, Calif., April 23 /PRNewswire-FirstCall/ -- Clarient, Inc., (NASDAQ:CLRT), a premier anatomic pathology and molecular testing services resource for pathologists, oncologists and the pharmaceutical industry, today announced that it has been granted an exclusive intellectual property license from the Indiana University Research and Technology Corporation (IURTC) for the rights to commercialize the FOXA1 biomarker, which predicts the likelihood of recurrence and long-term, disease-free breast cancer survival. The licensing of this intellectual property further strengthens Clarient's deep menu of molecular tests for breast cancer and will complement the Clarient Insight(R) Dx Breast Cancer Profile, which is expected to be released soon. The FOXA1 marker, also known as forkhead box A1, is a gene known to cause breast cancer. Recent data presented at the 2009 USCAP (United States and Canadian Academy of Pathology) meeting demonstrated that the expression of FOXA1, now known to be an estrogen receptor associated transcription factor, correlated with Oncotype Dx(R) when performed in patient samples from Indiana University. In this clinical study of 79 ER-positive, node-negative breast cancer patients, researchers found that FOXA1 expression identified the same low risk, ER-positive, node-negative patients who can be spared toxic chemotherapy (P=0.002). Researchers concluded Oncotype Dx and the FOXA1 marker can potentially be used interchangeably if further validation studies confirm the findings. Clarient CEO Ron Andrews noted that FOXA1 has shown it can predict risk of cancer recurrence in ER-positive, node-negative breast cancer patients. "Licensing FOXA1 and better understanding what advantages it might have over competitive tests will help put this marker on a rapid commercial track and support our mission to determine the most effective and reliable ways to evaluate breast cancer recurrence in women with early stage disease. Clearly, this marker is a tremendous addition to Clarient's rich menu in breast cancer," Andrews said. "It is also a significant new addition to our Clarient Insight Dx program, which aims to provide pathologists and oncologists with a panel of assays that help deliver personalized medicine in the community setting. Our dedication to translating cancer discovery and information into enhanced patient care is evidenced by our ability to license such coveted IP from prestigious institutions." "FOXA1 has also demonstrated an ability to differentiate between unique sets of breast cancer characteristics, which include luminal A and B subtypes," said Ken Bloom, M.D., Clarient's Chief Medical Officer. "Recent gene expression profiling studies have classified breast cancer into five distinct subtypes with unique molecular characteristics and prognostic significance," Dr. Bloom said. "Although both luminal subtype A and B correspond to ER-positive breast cancers, we have always known that luminal A subtype patients are associated with a significantly better prognosis in breast cancer. Clarient's agreement to license FOXA1 from IURTC provides for another strong marker to help identify these luminal A subtypes."
