The ProActive study will follow 3,000 kidney transplant patients over a three to five year period to examine the utility of the Prospera donor-derived cell-free DNA (dd-cfDNA) transplant assessment test to accurately identify organ rejection. The study is outpacing Natera's enrollment expectations with 18 top transplant centers already activated, more coming online in the near future, and 145 patients currently enrolled.
"The ProActive trial is a large, prospective registry study designed to provide valuable insights on clinical biomarkers, biopsy usage and clinical outcomes. Participation by top transplant centers in the
In the Prospera early access program, Natera has received tests from 45% of the top 50 and 37% of the top 100 transplant centers by volume. "The strong interest in Prospera and the significant number of top centers ordering tests during the early access program reflects a desire for more accurate, non-invasive testing methods, which Prospera fulfills through its ability to identify rejection with higher accuracy than first generation dd-cfDNA tests and current standards of care,"1,2 said

About the Prospera dd-cfDNA Organ Transplant 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. Prospera has been clinically and analytically validated for performance regardless of donor relatedness, rejection type, and clinical presentation. The test described has been developed and its performance characteristics determined by the CLIA-certified laboratory performing the test. The test has not been cleared or approved by the
