SOUTH SAN FRANCISCO, Calif., March 19, 2012 /PRNewswire/ -- diaDexus, Inc. (OTC Bulletin Board: DDXS), a company focused on proprietary cardiovascular diagnostic products, today highlighted data from two recent studies evaluating the clinical utility of its PLAC® Test for Lp-PLA(2) Activity. The PLAC® Test for Lp-PLA(2) Activity is CE-marked for use outside of the United States and is an investigational assay in the United States. This test, which measures the pro-inflammatory enzymatic activity of Lp-PLA(2), was used to examine patient samples from two well-known clinical studies of statins, LIPID and JUPITER.
"The LIPID analyses indicate that a reduction in Lp-PLA(2) levels may impact coronary heart disease outcomes more than a reduction in LDL cholesterol in response to statin therapy. In fact, the LIPID trial found that the more you lower Lp-PLA(2), the more you reduce the risk of coronary heart disease. This is compelling because Lp-PLA(2) levels have not been measured this way in prior studies," commented Brian E. Ward, Ph.D., diaDexus Chief Executive Officer.
"The JUPITER trial demonstrated that Lp-PLA(2) levels are predictive of cardiovascular events in apparently healthy men and women. Additionally, JUPITER showed a positive trend between lower Lp-PLA(2) levels and cardiovascular outcomes as a response to statins. Taken together, the LIPID and JUPITER analyses performed by our PLAC® Test for Lp-PLA(2) Activity should be of great interest to physicians, their patients and advisory bodies, especially as they understand the differences in the two study populations," Dr. Ward added.
The LIPID study population was comprised of patients who had a prior history of myocardial infarction or hospitalization for unstable angina; the JUPITER study included healthy men and women with elevated levels of C-reactive protein, an inflammatory marker. The individuals enrolled in these studies had markedly different cholesterol levels. LIPID patients had high LDL cholesterol levels between 155 to 217 mg/dL while the JUPITER patients had lower LDL cholesterol levels of 130 mg/dL or less at time of enrollment.

About the LIPID trial
The LIPID trial was a randomized controlled trial to determine the effects of cholesterol lowering on death from coronary heart disease among patients with coronary disease and average lipid levels. The trial was designed and initiated by Australian and New Zealand researchers including members of the Clinical Trials Research Unit of Auckland City Hospital, New Zealand. The trial involved 9014 patients, 3,056 of whom were recruited from New Zealand, and all of whom had a prior history of myocardial infarction or hospitalization for unstable angina. The study began in 1990 and was terminated at the end of 1997 (on the advice of the Data Monitoring Committee) as a result of evidence of a clear beneficial effect of pravastatin.
About the JUPITER trial
The JUPITER trial was a randomized, double-blind, placebo-controlled trial that investigated whether rosuvastatin 20 mg compared to placebo would decrease the rate of first major cardiovascular events. The trial enrolled 17,802 apparently healthy men and women with elevated levels of C-reactive protein. The trial was conducted by investigators in 26 countries and overseen by an academic statistician (Robert Glynn, PhD, Harvard University, USA) and an independent Data and Safety Monitoring Board (chaired by Professor Rory Collins, Oxford University, UK). The study was funded by AstraZeneca, US who had no access to unblinded trial data and played no role in analysis or interpretation of the study data or in manuscript preparation. Dr. Ridker, the JUPITER principal investigator, is listed as a co-inventor on patents held by Brigham and Women's Hospital that relate to the use of inflammatory biomarkers in cardiovascular disease that have been licensed to AstraZeneca.
