CareDx Showcases Leadership with Over 25 Oral Presentations and Posters at the International Society for Heart and Lung Transplantation Meeting

Data Highlights Clinical Utility of CareDx Solutions, Including Findings from Surveillance HeartCare Outcomes Registry (SHORE) Demonstrating Power of Multimodality Assessment for More Precise Interventions

CareDx Symposia Feature Latest Advancements Including XenoSure and XenoMap

SOUTH SAN FRANCISCO, Calif., April 20, 2022 (GLOBE NEWSWIRE) -- CareDx, Inc. (Nasdaq: CDNA) – The Transplant Company™ focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions for transplant patients and caregivers – today announced a leading presence at the International Society for Heart and Lung Transplantation (ISHLT) Annual Meeting and Scientific Sessions, with over 25 oral presentations and posters covering the latest innovations in heart and lung transplant surveillance and two symposia. ISHLT 2022 takes place on April 27-30 in Boston, Massachusetts.

CareDx showcases its leadership in heart and lung transplant patient care with a significant body of evidence highlighting the value of its diagnostic tools for heart and lung transplant recipients. Notably, oral presentations covering interim findings from the SHORE (Surveillance HeartCare Outcomes Registry) observational study will be presented, highlighting the value of multimodality assessment of heart transplant health for assessing the risk of rejection and de novo donor-specific antibodies (dnDSA). Additionally, CareDx symposia will spotlight leaders in the field delivering cutting-edge content using multimodality solutions, HeartCare, AlloMap® gene-expression profiling, and AlloSure® donor-derived cell-free DNA (dd-cfDNA).

“CareDx is proud of its history of innovation in cardiothoracic transplantation, with many firsts, from multimodality molecular assessment of allograft health, to donor-derived cell-free DNA for lung transplantation, to recently introducing, XenoSure™ and XenoMap™, for investigational use in xenotransplantation research,” said Reg Seeto, CEO and President of CareDx. “It’s extremely rewarding to have another remarkable presence at this year’s ISHLT meeting with extensive data elucidating the clinical value of integrating CareDx solutions and multimodality assessments into clinical practice.”

“The initial findings from the SHORE study build upon a growing literature that supports non-invasive surveillance of heart transplant patients with AlloSure donor-derived cell-free DNA and AlloMap gene-expression profiling. These studies provide a more comprehensive assessment of the health of the transplanted heart, which will hopefully lead to better outcomes for our patients through more tailored management strategies and earlier detection of graft injury,” said Dr. Jeffrey Teuteberg, MD, Cardiologist, and Associate Professor of Cardiovascular Medicine, Stanford Health Care. “Multimodality surveillance using both dd-cfDNA and gene-expression profiling may prove to be a better marker of immune quiescence or activation than endomyocardial biopsy (EMB) and questioning the place of the EMB as the gold standard for cardiac allograft monitoring.”

CareDx Lunch Symposia:

• Changing the Paradigm of Heart Transplant Surveillance with HeartCare, Wednesday, April 27, 12–1 PM EDT
• Advancing Care in Lung Transplantation: The Past, the Present and the Future, Thursday, April 28, 12:15–1:15 PM EDT
