Record Number of 65 Abstracts Showcasing CareDx Innovation Including Data Showing Clinical Utility of AlloSure Kidney to Guide Immunosuppression Management

Experts Review Advancements in Artificial Intelligence and Molecular Diagnostics During CareDx Symposium

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 2023 American Transplant Congress (ATC) with 65 scientific presentations. CareDx will also be hosting a satellite symposium¹ and sponsoring the Women’s Networking Event. The ATC meeting takes place June 3-7 in San Diego, California.

"We are proud to showcase our leadership with our highest-ever number of abstracts at the 2023 Transplant Congress with data that not only validates the performance of AlloSure® and AlloMap® but also demonstrates their clinical utility in the surveillance and management of patients,” said Reg Seeto, CEO and President of CareDx. “We're also excited to have assembled a world-class panel of experts to describe the latest innovations in transplantation including the additive clinical value of incorporating our molecular biomarkers into artificial intelligence tools to drive earlier insights regarding a patient’s risk of rejection for more personalized, preventative care.”

Noteworthy Presentations

AlloSure Kidney

• AlloSure donor-derived cell-free DNA (dd-cfDNA) and blood gene expression profiling used to guide immunosuppression minimization in patients on belatacept maintenance (B204). AlloSure used for immunologic surveillance of calcineurin inhibitor (CNI) intolerant patients and to guide transition to belatacept therapy (C145).
• Tissue gene expression and AlloSure Kidney used to guide treatment in patients presenting with T-Cell Mediated Rejection (TCMR) (oral abstract #73).
• Multinational multi-center validation of a predictive model showing the clinical value of adding AlloSure Kidney to assess patient risk of clinical and subclinical rejection (oral abstract #91).
• AlloSure dd-cfDNA provides less invasive monitoring for allograft function and survival. A combination of AlloSure, serum creatinine and biopsy can improve early detection of subclinical rejection and predict graft failure (C127).

HeartCare (AlloSure and AlloMap)

• One-year outcomes of patients on rejection surveillance protocol utilizing dd-cfDNA resulted in patients receiving significantly fewer biopsies and fewer treated rejection episodes, and had no difference in survival compared to patients on biopsy surveillance (oral abstract #30). Additionally, by using AlloSure dd-cfDNA, a heart transplant center was able to perform only one surveillance biopsy per patient without an increase in morbidity or mortality (BLB017).
• Greater elevations of AlloSure Heart and AlloMap Heart were associated with higher grades of biopsy confirmed Acute Cellular Rejection (ACR) (oral abstract #31).

AlloSure Lung Abstracts

• AlloSure Lung dd-cfDNA and plasma inflammatory markers can predict CLAD risk equivalent to or better than an invasive biopsy (oral abstract #33).

Satellite Symposium¹

Leading experts will discuss the latest advancements in kidney and heart transplantation during a symposium hosted by CareDx titled, “An Evolving Standard of Care: Artificial Intelligence and Molecular Diagnostics”. It will be held on Monday, June 5, from 12:15 to 1:15pm PT. Speakers include:

• Jonathan Bromberg, MD, PhD, Professor of Surgery, University of Maryland
• Giselle Guerra, MD, Medical Director, Transplant Services, Kidney Transplant Program, Miami Transplant Institute
• Gaurav Gupta, MD, Interim-Chair, Division of Nephrology, Medical Director, Kidney Transplant Program, Virginia Commonwealth University Health
• Jeffrey Teuteberg, MD, Professor of Medicine, Section Chief of Heart Failure, Cardiac Transplantation, and Mechanical Circulatory Support, Stanford University

“I’ve been a long-standing proponent of using non-invasive molecular diagnostics such as dd-cfDNA for surveillance to help overcome the inherent limitations of functional parameters and tissue biopsies in detecting early signs of rejection and for immunosuppression management,” said Giselle Guerra, MD, Medical Director, Transplant Services, Kidney Transplant Program, Miami Transplant Institute. “I look forward to sharing findings from my clinical practice on utilizing dd-cfDNA to make more personalized immunosuppression treatment decisions based on a patient’s risk stratification.”
