Study Reaffirms Benefits of AlloMap, the Industry’s Only Gene-Expression Profiling Blood Test, for Heart Transplant Rejection Surveillance

BRISBANE, Calif.--(BUSINESS WIRE)-- 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 new peer-reviewed publication showing that AlloMap^®, the industry’s only gene-expression profiling (GEP) blood test to non-invasively assess graft rejection by monitoring immune quiescence in heart transplant patients,¹ resulted in less pain and fewer adverse events compared to heart biopsy.² The study also highlights that the associated AlloMap blood test draw can be performed in the patient’s home to help reduce the risk of exposure to infection.

In an independent, prospective study performed at Baylor University Medical Center, forty-three heart transplant patients undergoing surveillance with a protocol that included both routine cardiac biopsy and AlloMap testing, reported significantly less pain and experienced fewer adverse events (no bleeding or swelling) with AlloMap than with biopsy.²

“We are extremely proud to offer patients AlloMap, the only test of its kind to non-invasively assess graft rejection by monitoring immune quiescence in heart transplant patients,” said Reg Seeto, CEO and President of CareDx. “Our dedication to improving the transplant patient journey is at the core of our mission and AlloMap improves patients’ quality of life by helping to reduce the pain and adverse events associated with an invasive biopsy procedure.”

These study results are consistent with the finding of improved patient satisfaction from the groundbreaking IMAGE (Invasive Monitoring Attenuation through Gene Expression) clinical utility trial published in the New England Journal of Medicine.³

“These real-world findings reiterate the value of using this non-invasive test in heart transplant patients. For these patients, an invasive heart biopsy procedure, which is more painful and fraught with potential adverse events is often not necessary, especially for asymptomatic surveillance,” said Shelley Hall, MD, Chief of Transplant Cardiology and Mechanical Support/Heart Failure, Baylor University Medical Center. “It’s great to have this reminder because often traditional biopsies are used when a less invasive test may be a much better option for many heart transplant patients.”

CareDx non-invasive heart transplant solutions, including AlloSure^® and AlloMap, have made transplant surveillance a less painful experience for patients. Gwen Chambers and Vang Her, both heart transplant recipients, share their experiences.

“I found biopsies very uncomfortable and scary because I'm awake and only mildly sedated while it's happening, which causes me a lot of anxiety," Gwen said. "If I had the option of AlloMap, that's hands-down my choice over biopsy to monitor my heart’s status because it’s a much less invasive and traumatic alternative. Hopefully, studies like this one will result in more patients having access to these tests so they can be spared the discomfort, trauma and anxiety resulting from invasive biopsies."

Vang Her added, "For me, biopsies involve painful catheterization through the neck or groin, which have left me bruised, stiff and sometimes with dangerous blood clots, including one in my heart, which took weeks to recover from. With CareDx testing, I receive a simple blood draw and experience no pain and no downtime, which means I can work without interruption, enjoy activities with my wife and kids, and train for the Iron Man competition."

AlloMap became commercially available in 2005 and has the distinction of being the only gene-expression profiling test that has been FDA cleared for use in heart transplant patients,¹ incorporated in International Society for Heart and Lung Transplantation guidelines, and covered by Centers for Medicare & Medicaid Services (CMS) both individually and for multimodality assessment using AlloSure donor-derived cell-free DNA. AlloMap is used in more than 90 percent of the nation’s heart transplant centers and in more than 1 in 2 newly transplanted patients.⁴ In 2020, CareDx launched HeartCare, which includes both AlloMap and AlloSure, to provide a comprehensive view of organ rejection by assessing immune quiescence and graft injury, and currently accounts for over 90 percent of AlloMap use.⁴
