CareDx’s Innovative, Non-Invasive Blood Tests Are Being Used as a Critical Tool to Help Assess Organ Health

SOUTH SAN FRANCISCO, Calif., Feb. 22, 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 that its non-invasive organ transplant surveillance solutions are being used to help monitor post-operative graft health in the world’s first successful heart xenotransplantation. A genetically modified pig heart was successfully transplanted into a patient at the University of Maryland Medical Center on January 7, 2022.

Surgeons from the University of Maryland School of Medicine (UMSOM) are using adapted versions of two complementary, non-invasive CareDx surveillance solutions, experimentally, to provide a comprehensive, multimodal assessment of organ graft health. Gene expression profiling is being used to assess immune quiescence and donor-derived cell-free DNA (dd-cfDNA) to detect graft injury.

“As an innovator in organ transplant surveillance, CareDx is proud to be working with UMSOM on this landmark case which represents a groundbreaking moment in the history of transplantation,” said Reg Seeto, CEO and President of CareDx. “It’s incredibly rewarding to apply our years of experience and dedication to the transplant community by offering the world’s first biomarker surveillance solution for xenotransplantation. We look forward to continuing to work closely with surgeons at UMSOM and the extended care team at the University of Maryland Medical Center to help ensure long-term success for this patient.”

“We are taking every precaution to ensure the optimal care of the world’s first successful transplantation of a genetically modified pig heart, including using CareDx’s non-invasive multimodality surveillance solutions to help monitor graft health,” said Dr. Bartley P. Griffith, Professor of Surgery and Clinical Director of the Cardiac Xenotransplant Program at UMSOM. Dr. Muhammad Mohiuddin, Professor of Surgery and Scientific Director of the Program in Cardiac Xenotransplantation at UMSOM, co-led the procedure with Dr. Griffith.

There is an organ shortage in the U.S. While most Americans support organ donation, only 58 percent are registered as organ donors.1 There is a great need for more donors with more than 100,000 Americans on the national transplant waiting list, and nearly 20 people die each day waiting for an organ transplant.2 Xenotransplantation may offer an alternative for people in need of a life-saving organ.

CareDx is dedicated to driving innovation in the transplant field. AlloMap® Heart was the first non-invasive blood test to monitor immune quiescence in heart transplant patients and AlloSure® was the first dd-cfDNA to monitor organ rejection in heart and kidney transplant patients. CareDx has served over 80,000 organ transplant patients with its AlloSure or AlloMap assays for their post-transplant care. More than 90 percent of the nation’s heart transplant centers, 70 percent of kidney transplant centers, and 40 percent of lung transplant centers use CareDx products to monitor their patients’ organ health.3
