CareDx reports over 200,000 heart transplant patients

SOUTH SAN FRANCISCO, Calif., April 14, 2022 (GLOBE NEWSWIRE) — CareDx, Inc. (Nasdaq: CDNA) – The Transplant Company™ is focused on the discovery, development and commercialization of clinically differentiated healthcare solutions and great value for transplant patients and caregivers – announced today that it has provided over 200,000 AlloMap® or AlloSure® results for over 30,000 heart transplant recipients.1

“We are proud to have a long-standing relationship of trust with the heart transplant community. Since 2005, we have served half of all heart transplant patients in the United States with AlloMap or AlloSure, and AlloMap has the distinction of being the only gene expression profiling (GEP) test approved by the FDA for use in heart transplants, the only GEP incorporated into International Society for Heart and Lung Transplantation Guidelines, and the only one covered by CMS for multimodality assessment using donor-derived AlloSure cell-free DNA,” said Reg Seeto, CEO and President of CareDx. “Most importantly, we have earned this trust by conducting prospective multicenter studies that have been published in leading journals such as New England Journal of Medicine.”

“It is exciting to see the widespread clinical adoption of CareDx’s transplant monitoring services since the company’s introduction of its first-of-its-kind product, AlloMap Heart, in 2005, and then AlloSure Heart in 2020,” said Jeffrey Teuteberg, MD, cardiologist, and associate professor of cardiovascular medicine, Stanford Health Care. “Evidence for the use of CareDx’s non-invasive tests for monitoring the transplanted heart has been demonstrated in numerous clinical studies,2-7and it is therefore not surprising that this important step for patients has been achieved.

In 2005, CareDx launched its first commercial product, AlloMap Heart, representing one of the first tests of its kind, a blood test to noninvasively monitor organ health in heart transplant recipients. AlloMap Heart then received FDA clearance in 20088 and is now used in over 90% of heart transplant centers in the United States1 In 2020, CareDx launched HeartCare which includes AlloMap gene expression profiling and AlloSure donor-derived cell-free DNA (dd-cfDNA). Together, these biomarkers provide a multimodal view of transplanted organ health by providing two distinct indicators of immune system activity and allograft health. CareDx’s HeartCare offering, which includes AlloMap Heart and AlloSure Heart, has an attachment rate of over 90%, reflecting the clinical utility of multimodal monitoring.
