AlloSure Featured in Journal of Applied Laboratory Medicine

Defines Cell-free DNA Levels in Stable Kidney Transplant Patients

BRISBANE, Calif., March 14, 2017 (GLOBE NEWSWIRE) -- CareDx, Inc. (Nasdaq:CDNA), a molecular diagnostics company focused on the discovery, development and commercialization of clinically differentiated, high-value diagnostic solutions for transplant recipients, announces a publication in the Journal of Applied Laboratory Medicine. This report describes the biological variation and clinical reference intervals of donor-derived cell-free DNA (dd-cfDNA) in stable healthy renal transplant recipients. 

Lead author Dr. Jonathan S. Bromberg, Vice Chair Research at the University of Maryland, School of Medicine, stated, "This report for the first time establishes the biological variation and reference intervals for the AlloSure® test in a population of clinically stable renal transplant recipients. The biological variability of the test in a reference renal transplant population is critical to the clinical interpretation of results in allograft recipients, who may undergo serial monitoring of dd-cfDNA to assess the status of the allograft." 

Key Findings:

This reference population was selected from the cohort of subjects enrolled in the DART study (Circulating Donor-Derived Cell-Free DNA in Blood for Diagnosing Acute Rejection in Kidney Transplant Recipients, NCT02424227) Rigorous demonstration of the assay analytical variation of the clinical-grade AlloSure assay used in this study was critical to these findings.

James P. Yee M.D., Ph.D., Chief Medical Officer at CareDx, Inc. said, "This report is important for the clinical interpretation of AlloSure test results as it assists clinicians to stratify their patients, and manage their care accordingly.  The AlloSure level offers a new criterion that clinicians may consider in addition to other conventional factors used to make decisions regarding immunosuppressive medications in individual renal transplant patients."

ABOUT THE JOURNAL OF Applied Laboratory Medicine:

The Journal of Applied Laboratory Medicine (JALM) is an international, peer-reviewed AACC publication that showcases clinically relevant laboratory topics in applied and translational research, and thoughtful commentary on the practice of clinical chemistry and laboratory medicine. Through JALM the AACC aims to provide a resource to laboratory professionals and the healthcare team for discovering new adaptive solutions for meeting patient care challenges and driving innovation in the field of laboratory medicine.  JALM also aims to provide Laboratory professionals and the healthcare team with interpretive guidance so that patients receive the most effective care available.  As such, JALM focuses on cutting edge research in applied and translational laboratory medicine.  JALM will consider submissions for publication on laboratory methods, evidence-based laboratory medicine, flow cytometry, hemostasis, management, health economics, best practices, test utilization, critical care, and pediatric testing. Additionally, the journal will provide a forum for discussion of policy and regulatory issues that impact the field.

About CareDx
CareDx, Inc., based in Brisbane, California, is a molecular diagnostics company focused on the discovery, development and commercialization of clinically differentiated, high-value, non-invasive diagnostic surveillance solutions for transplant recipients. The Company has commercialized AlloMap®, a gene expression test that aids clinicians in identifying heart transplant recipients.  CareDx is also pursuing the development of additional products for post-transplant monitoring of other solid organs that use a variety of technologies, including next generation sequencing, to detect donor-derived cell-free DNA to monitor the health of organs after transplantation.

CareDx, with its presence through Olerup, also develops, manufactures, markets and sells high quality products that increase the chance of successful transplants by facilitating a better match between a donor and a recipient of stem cells and organs.
