Natera to Present New Signatera™ Colorectal Cancer Data at ESMO Showing 10X Advantage in Overall Survival

Presentations include abstracts from the GALAXY arm of the CIRCULATE-Japan trial, along with new data in Breast Cancer and Squamous Cell Carcinoma of the Head and Neck

AUSTIN, Texas, September 09, 2024--(BUSINESS WIRE)--Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and genetic testing, today announced it will present new data on its personalized and tumor-informed molecular residual disease (MRD) test, Signatera, at the 2024 European Society for Medical Oncology (ESMO) Congress taking place Sept. 13-16 in Barcelona, Spain.

Natera and its collaborators will present a total of nine abstracts, including five poster presentations from the GALAXY observational arm of the CIRCULATE-Japan trial, one of the largest and most comprehensive prospective studies of MRD testing in resectable colorectal cancer (CRC).

The GALAXY data includes an updated analysis of more than 2,100 patients with stage I-IV CRC, reporting 36-month disease-free survival (DFS), and, for the first time, overall survival (OS). Key highlights include:

  • Signatera-positive patients had significantly shorter OS compared to those who were Signatera-negative (hazard ratio of ~10), suggesting that Signatera-negative patients had an almost 10-fold advantage in OS. This compares favorably to all known guideline recommended biomarkers that typically have hazard ratios for overall survival in the 1-4 range.

  • Overall survival stratified by adjuvant chemotherapy (ACT) will also be presented. This will build on prior GALAXY DFS data which has shown significant benefit of ACT in Signatera-positive patients, but lack of benefit in Signatera-negative patients. The current standard of care is based on studies showing that most CRC patients derive a small ~0-5% absolute and ~10-20% relative OS benefit from ACT. Identifying subgroups where this benefit is concentrated is critical for advancing clinical management of early-stage CRC.

"ESMO 2024 will showcase some of our most impactful data in colorectal cancer to-date," said Minetta Liu, MD, chief medical officer of oncology at Natera. "Notably, we will present an updated analysis from the GALAXY arm of CIRCULATE-Japan with the first prospective read-out of overall survival based on MRD. These findings underscore the potential for Signatera to predict long-term outcomes."

Other presentations at ESMO will highlight new Signatera data in breast cancer and squamous cell carcinoma of the head and neck. Below is the full list of presentations:
