CareDx Showcases Latest Advances Across AlloSeq Lab Products Portfolio at the 36 th European Immunogenetics and Histocompatibility Conference

CareDx, Inc. (Nasdaq: CDNA), a leading precision medicine company focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions for transplant patients and caregivers – today announced that it will showcase the latest developments across its AlloSeq®* portfolioduring the 36^th European Immunogenetics and Histocompatibility Conference taking place April 26-29 in Nantes, France.

“We look forward to participating in this meeting and presenting our latest innovations for the European transplant community with our AlloSeq* portfolio of lab products for research and clinical use pre- and post-transplantation,” said Reg Seeto, CEO and President of CareDx. “We are committed to advancing the field of immunogenetics and histocompatibility and take great pride in supporting this important event as a platinum sponsor.”

CareDx will be on hand to display its leadership in serving European laboratories, researchers, and clinicians with its best-in-class product portfolio of next-generation sequencing (NGS) based AlloSeq* products, which enables best-in-class care both pre- and post-transplantation.

For pre-transplant, CareDx offers AlloSeq Tx* HLA typing solutions. For post-transplant, CareDx offers AlloSeq HCT* chimerism testingand AlloSeq cfDNA* for labs to assess transplanted stem cells and organ health, respectively. CareDx also provides pre-transplant HLA typing and post-transplant surveillance testing for customers through its service lab in Stockholm, Sweden, for clinical research.

CareDx will sponsor a symposium “Breaking New Ground: Innovative Pre- and Post-Transplant Solutions to Improve Allograft Outcomes” on Thursday, April 27. The event will be moderated by Curtis Lind, CareDx Vice President and Head of R&D products. Panelists and topics include:

• Monica Irina Dutescu M,D., Ph.D.,National HLA Laboratory, National Institute of Blood Transfusion Prof. Dr. C.T. NICOLAU Bucharest, Romania: High Resolution HLA Typing with AlloSeq Tx – the Experience of National HLA Laboratory, Bucharest.
• Miguel Alcoceba Ph.D., Department of Haematology, University Hospital of Salamanca (HUS-IBSAL) Salamanca, Spain: Comparison of Next-Generation Sequencing and Short-Tandem Repeats to Monitor Chimerism Analysis.
• Olivier Aubert M.D., Ph.D., Necker-Enfants Malades Hospital - Paris Transplant Group, Paris, France: dd-cfDNA in Allograft Rejection and Risk Assessment.

“I look forward to participating in the CareDx sponsored symposium and showing how its innovative HLA typing solutions represent a strong, efficient, and user-friendly technique for pre-transplant testing, that provides reliable, accurate results. I will also demonstrate how the use of its hybrid capture method can also provide the best coverage, high level of transplant matching and low rates of ambiguity in one product,” said Monica Irina Dutescu, M.D., Ph.D., National Institute of Blood Transfusion, Bucharest.

The following nine AlloSeq* oral presentations and posters will be presented at the meeting.
