Data from AiKidney Helps Clinicians Gain New Insights into Patient’s Risk of Allograft Rejection

CareDx to Host Investor Event to Share More Information About AiKidney, Clinical Pipeline and Using Augmented Information in Transplantation

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 it plans to expand its growing multimodality portfolio with AiKidney™, a new allograft risk assessment clinical decision support tool, in development, that includes AlloSure® and other transplant metrics.

This follows CareDx’s recently announced plans to add an artificial intelligence (AI) prognostic for cardiac allograft vasculopathy (CAV). Presentations covering these developments will occur during the 2022 Transplant Congress on June 4-8 in Boston, Massachusetts.¹

AiKidney delivers information about a patient’s current risk of rejection and a prognosis of allograft survival at three, five, and seven years. AiKidney can be used for informing clinical management decisions and to help clinicians predict the long-term impact of treatments. As transplant patient care becomes more complex, with an increasing focus on optimizing immunosuppression and long-term care, AlloSure is the only donor-derived cell-free DNA (dd-cfDNA) solution that features this additive AI-enabled risk assessment algorithm.

“CareDx is driving the next wave of transplant innovation with multimodality that amplifies the power of AlloSure by incorporating artificial intelligence.² AiKidney has the potential to set a new standard of care through precision medicine by generating new insights to support earlier interventions or to modulate immunosuppression when assessing the risk of rejection by physicians,” said Reg Seeto, CEO and President of CareDx. “This approach aligns very much with our mission of improving long-term outcomes through innovative solutions.”

“We’re proud to work with CareDx to apply innovative digital health solutions to drive earlier data-driven interventions with molecular precision,” said Dr. Alex Loupy, Founder of OrganX. “This ongoing partnership is yielding positive results and it is exciting to see AiKidney coming to fruition in the clinic.”

“Studies have shown the effectiveness of CareDx’s multimodality solutions for routine kidney transplant surveillance and for identifying immune-quiescence,”^3-5 said Miklos Z. Molnar, MD, PhD, Professor of Medicine and Medical Director of Kidney and Pancreas Transplantation at University of Utah. “AiKidney supports this assessment by providing information about a patient’s risk of allograft rejection and expected long-term graft survival. I am excited with innovations such as this one that have the potential to help prolong kidney allograft survival which remains suboptimal at the 10-year mark. “

Transplant Congress Presentations Highlight the Utility of AI-Enabled Risk Assessments:

• CareDx Product Theatre: The Predictive Power of AlloSure and AiKidney, Sunday, June 5, 9:30–10:00 am ET, Theatre A, Exhibit Hall C

• CareDx Lunch Symposium: A Window to a New World: Multi-Modality Molecular Characterization & Prediction of Allograft Outcomes, Tuesday, June 7, 12:45 – 1:45pm ET.

CareDx Innovation Day:

• Artificial Intelligence in Transplantation and CareDx Clinical Pipeline, Tuesday, June 7, 2:00 -3:00pm ET. The event will be held in a hybrid format to enable a wide audience to participate. To learn more and sign up, register here.

Long-term kidney transplant failure is a serious issue and begins to accelerate three years post-transplantation. Kidney failure rates⁶ are approximately 15 percent at three years, 21 percent at five years and 48 percent at ten years.⁷ Graft injury and rejection are the main reasons for transplant failures, excluding death. Adding to the problem is a serious kidney organ shortage. Over 90,000 Americans are on the waiting list for a kidney transplant, and about 13 people die each day waiting for one.⁸ Conventional kidney transplant biomarkers (e.g. serum creatine) are lagging indicators of kidney transplant rejection. Innovations from CareDx have the potential to inform earlier, data-driven interventions which have the potential to improve long-term outcomes.
