Noridian Posts Favorable Draft Local Coverage Determination for Natera's Prospera(TM) Kidney Transplant Test
SAN CARLOS, Calif., May 21, 2019 /PRNewswire/ -- Noridian, the Medicare Administrative Contractor (MAC) for California-based laboratories, has posted a favorable draft local coverage determination (LCD) for use of Natera's Prospera™ test to assess active rejection in kidney transplant recipients.
In its LCD, Noridian states, "Prospera is an effective, non-invasive method of assessing kidney allograft status with better performance than the current standard-of-care." It also states, "The evidence is sufficient to support that Prospera provides a non-invasive assessment tool to assess for the presence of active allograft rejection." Furthermore, "The evidence also supports that Prospera identifies both ABMR [antibody-mediated rejection] and TCMR [T-cell mediated rejection], and it is validated to detect subclinical AR [active rejection]." Final LCD issuance is expected soon, allowing Natera to submit claims for Medicare patients.
"I am pleased with our progress towards achieving Medicare coverage for patients with the greatest need," said Paul Billings, MD, PhD, Natera's Chief Medical Officer.
There are more than 190,000 people living with a kidney transplant in the U.S.1 and roughly 20,000 new kidney transplant surgeries are performed each year.2 It is estimated that 20-30 percent of organ transplants fail within five years, and approximately 50 percent fail within 10 years.3,4 Traditional tools for diagnosing organ transplant rejection are either invasive (biopsies) or inaccurate (serum creatinine), creating a strong unmet need for better diagnostic tools to help optimize immunosuppression levels, avoid unnecessary biopsies, and improve graft survival.
The proposed LCD is posted on the Centers for Medicare and Medicaid Services website and is subject to public comments and further Medicare review before it is finalized.
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 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 independent of donor type, rejection type, and clinical presentation. In repeatability and reproducibility studies, it showed superior precision with a coefficient of variation up to five times better than that of a competitive dd-cfDNA assay (1.85% vs. 9.2% within run; 1.99% vs. 4.5% across runs).5,6 In clinical validation, Natera reported higher sensitivity (89% vs. 59%) and higher area under the curve (0.87 vs. 0.74) than the competing dd-cfDNA assay.7,8
