Natera Announces New Signatera™ MRD Data at 2023 AACR Annual Meeting

AUSTIN, Texas--(BUSINESS WIRE)-- Natera Inc. (NASDAQ: NTRA), a global leader in cell-free DNA testing, today announced new data on its Signatera molecular residual disease (MRD) test being presented at the annual meeting of the American Association for Cancer Research (AACR) taking place April 14 – 19, 2023.

Natera and its collaborators will present findings from five studies on Signatera in esophago-gastric adenocarcinoma, muscle-invasive bladder cancer (MIBC), colorectal cancer (CRC) and hepatocellular carcinoma (HCC). Highlights include:

• ctDNA prediction of tumor response and recurrence in patients with esophago-gastric carcinoma receiving FLOT + immunotherapy (avelumab) pre- and post-surgery

• ctDNA prediction of tumor response and recurrence in patients with MIBC, with and without neoadjuvant therapy, with long term follow-up (median 68 months) after radical cystectomy

• Genomic profiling of >13,000 patients with early (≤50 years old) vs late (≥60 years old) onset CRC

• Potential of ctDNA to guide imaging-based surveillance strategies in patients after surgery for peritoneal metastases from CRC

• ctDNA as a pharmacodynamic and predictive biomarker in patients with resectable HCC treated with immunotherapy (cemiplimab) pre- and post-surgery

“We are pleased to share additional Signatera data at this year’s AACR annual meeting that continues to highlight the important role of personalized MRD testing in assessing treatment response and predicting relapse across a broad range of indications,” said Minetta Liu, M.D., chief medical officer of oncology at Natera. “These data presentations underscore Natera’s commitment to generating novel insights on MRD testing and genomic testing to help advance cancer care.”

About Signatera

Signatera is a custom-built circulating tumor DNA (ctDNA) test for treatment monitoring and molecular residual disease (MRD) assessment in patients previously diagnosed with cancer. The test is available for both clinical and research use, and has been granted three Breakthrough Device Designations by the FDA for multiple cancer types and indications. The Signatera test is personalized and tumor-informed, providing each individual with a customized blood test tailored to fit the unique signature of clonal mutations found in that individual’s tumor. Signatera is intended to detect and quantify cancer left in the body, at levels down to a single tumor molecule in a tube of blood, to identify recurrence earlier and to help optimize treatment decisions.
