Under a multi-year agreement, clinicians will be able to order blood draws on patients for testing through Quest's approximately 2,200 patient service centers and 4,000 phlebotomists in physician offices in the United States. Samples will be forwarded to CardioDx's CLIA-certified laboratory (in Redwood City, Calif.) for testing.

- Funding Slated for Further Commercial Deployment of the Corus® CAD Blood Test and Continued Development of Next Generation Products -
REDWOOD CITY, CA – December 18, 2014 - CardioDx, Inc., a molecular diagnostics company specializing in cardiovascular genomics, today announced the close of $35 million in total equity financing. Alberta Investment Management Corporation (AIMCo) participated in this round together with the company's existing investors.

- Patients with Low Corus CAD Scores Had a 95% Decreased Rate of Referral for Advanced Cardiac Testing Versus Patients with Elevated Corus CAD Scores -

REDWOOD CITY, Calif. – [October 20, 2014] - CardioDx, Inc., a molecular diagnostics company specializing in cardiovascular genomics, today announced the presentation of the study, “The Use of a Gene Expression Score Showed Clinical Utility in Evaluating African Americans Presenting with Symptoms Suggestive of Obstructive Coronary Artery Disease in a Primary Care Practice,” at the 36th Annual North American Meeting of the Society for Medical Decision Making, taking place from Oct. 18-22 in Miami.

- Blood-Based Test Has Potential to Improve Quality of Care and Lower Costs of Evaluation of Obstructive Coronary Artery Disease -
REDWOOD CITY, Calif. – [July 7, 2014] - CardioDx, Inc., a molecular diagnostics company specializing in cardiovascular genomics, confirmed today that Aetna has established a clinical policy for the company’s Corus® CAD gene expression test. With this decision, the Corus CAD gene expression test is eligible for coverage among Aetna and Coventry Health members. Aetna considers the Corus CAD gene expression test medically necessary for evaluation of non-diabetic adults with chest pain or anginal equivalent symptoms who have no history of obstructive coronary artery disease.

- Patients with a Low Corus CAD Score had 94% Reduced Odds of Referral to a Cardiologist -

- REGISTRY I Study Results Add to the Established Evidence Base Supporting the Clinical Utility of the Corus CAD Gene Expression Test in Real-World Clinical Practice -

PALO ALTO, Calif. – [May 05, 2014] - CardioDx, Inc., a molecular diagnostics company specializing in cardiovascular genomics, today announced the publication of the REGISTRY I study, which examined the assessment of non-acute chest pain and related symptoms that may be suggestive of obstructive coronary artery disease (CAD) in the primary care setting with the Corus® CAD blood-based gene expression test. The study, published online in the American Journal of Medical Quality in May 2014, found a strong association between cardiac referral rates by low (≤15) and elevated (>15) Corus CAD score groups, with only 6% (10/167) of the low Corus CAD score patients versus 70% (122/175) of the elevated Corus CAD score patients being referred for further cardiac evaluation (P < .0001). Corus CAD is the first and only commercially available blood-based gene expression test that provides a current-state assessment of obstructive CAD in non-diabetic patients presenting with typical or atypical symptoms. With a 96% negative predictive value and 89% sensitivity, Corus CAD can help clinicians accurately rule out obstructive CAD as the source of their patients’ symptoms, so that they may investigate other non-cardiac causes.

- IMPACT-PCP Study Results Reinforce the Clinical Utility of Corus CAD in the Primary Care Setting, Where Almost 8,000 Patients Present With Non-Acute Chest Pain and Related Symptoms Every Day -

- Clinicians Modified Their Diagnostic Strategy in 58% of Patients Following a Corus CAD Test Score -

PALO ALTO, Calif. – March 10, 2014 – CardioDx, Inc., a molecular diagnostics company specializing in cardiovascular genomics, today announced the publication of the IMPACT-PCP (Investigation of a Molecular Personalized Coronary Gene Expression Test on Primary Care Practice Pattern) trial reinforcing the value of Corus® CAD as an initial diagnostic test for the evaluation of patients presenting with non-acute symptoms suggestive of obstructive coronary artery disease (CAD) in the primary care setting. The study appears in the March 2014 issue of the Journal of the American Board of Family Medicine.
