Natera Announces Results of Large, Multi-Center Clinical Experience Study Showing Excellent Positive Predictive Value of the Prospera™ Kidney Test
Natera, Inc. (NASDAQ: NTRA) announced the results of a large real-world study confirming the effectiveness of its Prospera donor-derived cell-free DNA (dd-cfDNA) test for kidney transplant patients. Conducted across 33 clinics with 879 patients, the study reported a 64% positive predictive value in detecting active rejection among those with high-risk results. The findings, published in Transplantation Proceedings, indicate that dd-cfDNA testing can enhance physician decision-making in managing transplant patients. This adds to existing evidence supporting the Prospera test's clinical utility.
- 64% positive predictive value of Prospera test in detecting active rejection.
- Study included 879 patients across 33 clinics, validating real-world effectiveness.
- Prospera test continues to gain recognition as a critical tool for transplant monitoring.

AUSTIN, Texas, Feb. 17, 2022 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, announced the results of a large, real-world study confirming strong performance of its Prospera donor-derived cell-free DNA (dd-cfDNA) test in assessing rejection for kidney transplant patients.
The study, published in Transplantation Proceedings, reports the real-world impact of dd-cfDNA on patient management in a multi-center, real-world clinical cohort, including 879 patients evaluated from 33 participating clinics. Eighteen of the 28 patients with biopsy-matched high-risk Prospera dd-cfDNA test results were confirmed to have active rejection, demonstrating a reported
"The Prospera dd-cfDNA test continues to solidify its role as an important tool for monitoring the graft health of transplant patients," said Yasir Qazi, M.D., associate professor of clinical medicine and medical director of the kidney-pancreas transplant outreach and fellowship program at the Keck School of Medicine of USC, principal investigator and lead author of the study. "It was exciting to see a strong performance in real-world clinical settings across leading institutions."
This study adds to the growing body of evidence supporting Prospera dd-cfDNA testing, including the Trifecta study, the largest prospective, biopsy-matched, multi-center study to date in the field of kidney transplantation, currently submitted for publication.
About the Prospera test
The Prospera test leverages Natera's core single-nucleotide (SNP)-based massively multiplexed PCR (mmPCR) technology to identify allograft rejection non-invasively and with high precision and accuracy, without the need for prior donor or recipient genotyping. The test works by measuring the fraction of donor-derived cell-free DNA (dd-cfDNA) in the recipient's blood. It may be used by physicians considering the diagnosis of active rejection, helping to rule in or out this condition when evaluating the need for diagnostic testing or the results of an invasive biopsy. The Prospera test has been clinically and analytically validated for performance regardless of donor relatedness, rejection type, and clinical presentation. It has been developed and its performance characteristics determined by Natera, the CLIA-certified laboratory performing the test. The test has not been cleared or approved by the US Food and Drug Administration (FDA). CAP accredited, ISO 13485 certified, and CLIA certified.
