100,000th AlloMap Result Provided to Heart Transplant Patients

BRISBANE, Calif., July 13, 2017 -- CareDx, Inc. (NASDAQ:CDNA), a molecular diagnostics company focusing on the discovery, development and commercialization of clinically differentiated, high-value diagnostic solutions for transplant patients, announced today that the landmark 100,000^th AlloMap result has been provided.

The increasing use of AlloMap contributes to this milestone. More than 90% of US heart transplant centers are now using the guideline-recommended AlloMap for heart transplant patient surveillance. “AlloMap has become a standard of care to monitor heart transplant patients for probability of rejection,” said Mario Deng, MD, cardiologist and professor of medicine at UCLA. “For a transplant patient, understanding the health of their allograft is the top priority and drives many clinical decisions we make on immunotherapy and dose levels. The wide adoption of AlloMap and its longitudinal variation, AlloMap Variability Score, highlights the informative value of novel diagnostic solutions for this highly complex patient population.”

Mitch Nelles, Chief Operations Officer at CareDx stated, “This marks an impressive milestone for AlloMap. We at CareDx are focused on timely delivery of a non-invasive solution for heart transplant patients to replace or complement invasive biopsies. Convenient and secure access to the test results are readily available to the healthcare providers and patients through the CareDx web portal. The combination of these data with the CareDx-supported Outcomes of AlloMap Registry (OAR) provide rich content and clinical insights for the “Big Data” analytics project that has been presented at national meetings.”

CareDx, a leader in transplant diagnostics solutions, has a deep understanding of the continuing diagnostic needs for transplant patients. CareDx will build on the success of AlloMap later this year with the launch of AlloSure, an advanced diagnostic test for kidney transplant patients.
