Natera Announces New Prospera™ Data at the ATC 2021 Virtual Connect Conference
Natera, Inc. (NASDAQ: NTRA), a leader in cell-free DNA testing, announced its participation in the American Transplant Congress (ATC) 2021 Virtual Connect from June 4-9. The company will present new scientific data on its Prospera test, which evaluates organ transplant rejection. Presentations include findings from leading physicians, emphasizing the importance of cfDNA in timely decision-making for nephrologists. The Prospera test enhances rejection assessment by measuring donor-derived cfDNA, having shown improved sensitivity in recent studies.
- New data presented on the performance of the Prospera test in assessing organ transplant rejection.
- The Prospera test has demonstrated improved sensitivity for detecting active rejection events.
- None.
AUSTIN, Texas, June 4, 2021 /PRNewswire/ -- Natera, Inc. (NASDAQ: NTRA), a pioneer and global leader in cell-free DNA (cfDNA) testing, today announced it will present new data on its latest scientific innovations in cfDNA testing at the American Transplant Congress' (ATC) 2021 Virtual Connect, taking place June 4-9, 2021.
Three posters showcasing the scientific progress and performance of the Prospera test will be presented along with four sponsored presentations featuring leading transplant physicians.
"We look forward to sharing our latest findings with the transplant community and believe these innovations will play an important role in helping nephrologists make more timely and informed decisions about the health of their patients' transplanted organs," said Bernie Tobin, Natera's general manager of organ health.

Details about the abstract presentations are as follows:
Abstract #LB 76 | Poster Presentation | Presenter: Suphamai Bunnapradist, M.D., M.S.
Detection of rejection in kidney transplant patients using an algorithm that combines donor fraction and dd-cfDNA quantity
Results of a study incorporating the dd-cfDNA fraction with the dd-cfDNA quantity shows improved performance of the Prospera test to assess active rejection. The application of these two values resulted in an increased sensitivity.
Abstract #LB 19 | Oral Presentation | Presenter: Philip F. Halloran, M.D.
Relationship between %dd-cfDNA, MMDx molecular diagnoses, and donor-specific antibody in the Trifecta study
Investigating the relationship between dd-cfDNA, donor-specific antibody (DSA) status, and molecular characteristics of 176 kidney biopsies, as part of the Trifecta study. It finds that dd-cfDNA levels at the time of indication biopsy are highly correlated with class II DSA and rejection status. In addition, this talk will show that many cases of antibody-mediated rejection are DSA negative but still release high levels of dd-cfDNA.
Abstract #322 | Oral Presentation | Presenter: Philip F. Halloran, M.D.
The Trifecta study: Calibrating circulating donor-derived cell-free DNA at the time of indication biopsies against the molecular phenotype of the biopsy reveals a prominent association with NK cell genes
This Trifecta study analysis looks at 300 kidney biopsy samples from 14 centers using MMDx and Prospera test technologies. Genome-wide gene expression profiling indicates that natural killer cell genes, interferon gamma-induced genes and the molecular classifications of active rejection are strongly correlated with dd-cfDNA levels at the time of indication biopsy.
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.
