OKRA Multi-Center Prospective Study Confirms AlloMap Kidney Detects ABMR and TCMR Allograft Rejection

SOUTH SAN FRANCISCO, Calif., May 05, 2022 (GLOBE NEWSWIRE) -- CareDx, Inc. (Nasdaq: CDNA) – The Transplant Company™ focused on the discovery, development, and commercialization of clinically differentiated, high-value diagnostic solutions for transplant patients – today announced the publication1 of new data demonstrating that AlloMap® Kidney gene-expression profiling predicts the probability of allograft rejection for both antibody-mediated rejection (ABMR) and T cell-mediated rejection (TCMR).

The new data, published in Biomarkers in Medicine, combining multiple data sets, including the multi-center, prospective OKRA (Outcomes of KidneyCare in Renal Allografts) study (NCT03326076), shows that AlloMap Kidney can reliably discriminate rejection from quiescence in kidney transplant patients with a negative predictive value of 95%. The results are consistent with previously published clinical validation study results.2

“This multi-center study delivers further evidence that AlloMap Kidney comprehensively assesses immunological risk of rejection,” said Reg Seeto, CEO and President of CareDx. “This moves us one step closer to being able to offer our multimodality KidneyCare solution to clinicians, an innovative new advancement for kidney transplant patients.”

“It’s exciting to see the data confirming the performance of AlloMap Kidney, on the heels of the landmark ADMIRAL study3, which showed that AlloSure Kidney improves upon standard of care serum creatine for rejection surveillance and is an effective non-invasive service that can be used routinely to assess clinical and subclinical rejection,” said Dr. Yasir A. Qazi, Associate Professor of Clinical Medicine at Keck School of Medicine. “Together, these two biomarkers, gene-expression profiling and donor-derived cell-free DNA, will provide meaningful new insights to better personalize immunosuppression medication to prevent rejection and to safely reduce immunosuppression in patients with stable quiescent immune activity.”

CareDx is an innovator in multimodality transplant solutions. HeartCare, which includes AlloSure and AlloMap for heart transplant patients, is utilized by the majority of heart transplant centers in the United States.4 CareDx is bringing its deep expertise in multimodality care to the kidney transplant community with the eventual commercialization of KidneyCare.
