Diadexus, Inc. (OTCQB: DDXS), a diagnostics company developing and commercializing products that aid in the prediction of cardiac disease risk, and Mayo Clinic recently signed an agreement to collaborate in the areas of education, research, and innovation on the PLAC® Test for Lp‑PLA2 Activity. The test, which has been cleared by the U.S. Food and Drug Administration, is used to help identify risk for coronary heart disease in patients with no history of cardiovascular events.
As part of the agreement, Mayo Clinic’s Department of Laboratory Medicine and Pathology will participate in the Diadexus Laboratory Partnership Program, where Diadexus will provide educational support during the proper integration and use of Lp‑PLA2 Activity testing in the clinical practice. Once fully integrated, the test will be available to patients and providers worldwide through Mayo Clinic’s reference laboratory Mayo Medical Laboratories, which offers advanced laboratory testing and pathology services to more than 5,000 health care organizations.
“The PLAC Test for Lp‑PLA2 Activity is an advanced tool that has demonstrated a unique and independent value in assessing the risk of heart attack, cardiovascular death, and the need for revascularization in patients at risk of such a first event,” says Kenneth Fang, M.D., chief medical officer of Diadexus. “The collaboration with Mayo Clinic will provide valuable leadership in education and research and access to this robust new cardiovascular biomarker test.”
“Research has shown that the use of lipid panel testing is often not sufficient for identifying a patient’s risk for heart disease. When there is ambiguity, the measurement of Lp-PLA2 activity levels can be extremely helpful in defining those at risk” says Allan Jaffe, M.D., consultant and chair of the Division of Clinical Core Laboratory Services at Mayo Clinic, with a joint appointment in the Division of Cardiovascular Diseases. “The ability for us to integrate this assay directly into our laboratory facilities at Mayo will help us better identify those at risk and allow for appropriate interventions.”
“Mayo Clinic is a leader in cardiovascular disease treatment and biomarker testing, and we are honored to work with the organization,” says Lori Rafield, Ph.D., chairman and CEO for Diadexus. “This collaboration will improve patient care by providing cardiovascular patients of Mayo Clinic and clients of Mayo Medical Laboratories with a much more robust test for a clinically validated biomarker.”
Dr. Allan Jaffe is a paid scientific adviser to Diadexus.
About the PLAC® Test for Lp-PLA2 Activity
The PLAC® Test for Lp-PLA2 Activity, cleared by the U.S. FDA in December 2014, is to be used in conjunction with clinical evaluation and patient risk assessment as an aid in predicting risk of coronary heart disease in patients with no prior history of cardiovascular events, a population that represents approximately 75 percent of coronary heart disease patients. Lp-PLA2 (lipoprotein-associated phospholipase A2) is a cardiovascular risk marker supported by a decade of peer-reviewed literature. Lp-PLA2 provides important new information about blood vessel inflammation, over and above the traditional risk factors measured on a lipid panel.
About Diadexus, Inc.
Diadexus, based in South San Francisco, California, is a diagnostics company developing and commercializing products that aid in the prediction of cardiac disease risk, providing health care providers with actionable information for managing patients. The company pioneered the testing of Lp-PLA2 (lipoprotein-associated phospholipase A2), a marker of vascular-specific inflammation that provides new information, over and above traditional risk factors measured in a lipid panel, and has more than a decade of peer-reviewed literature validating its utility. Diadexus’ products, The PLAC® Test ELISA Kit, first cleared by the FDA in 2003, and The PLAC® Test for Lp-PLA2 Activity, cleared in December 2014, are the only two FDA-cleared tests to measure Lp-PLA2.
The company also has a pipeline of biomarkers for heart failure: proADM, proET-1, and proANP — each providing distinct, additive information for healthcare providers over currently available markers. Diadexus also provides services to pharmaceutical partners to address the need to incorporate biomarkers in clinical development.
