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
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
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:

About Signatera
Signatera is a personalized, tumor-informed, molecular residual disease test for patients previously diagnosed with cancer. Custom-built for each individual, Signatera uses circulating tumor DNA to detect and quantify cancer left in the body, identify recurrence earlier than standard of care tools, and help optimize treatment decisions. The test is available for clinical and research use and is covered by Medicare for patients with colorectal cancer, breast cancer, ovarian cancer and muscle invasive bladder cancer, as well as for immunotherapy monitoring of any solid tumor. Signatera has been clinically validated across multiple cancer types and indications, with published evidence in more than 70 peer-reviewed papers.
