Insights
The GALAXY study results represent a significant advancement in colorectal cancer (CRC) management. The data demonstrates Signatera's remarkable ability to predict overall survival and chemotherapy benefit. Key findings include:
- Signatera-positive patients showed a 9.68 times higher risk of death compared to Signatera-negative patients.
- Signatera-positive patients receiving adjuvant chemotherapy (ACT) had a
50% reduced risk of death, surpassing the16% reduction seen in the MOSAIC trial. - Sustained Signatera clearance after ACT correlated with 100% 24-month overall survival.
These results suggest Signatera could revolutionize CRC treatment decisions, potentially sparing Signatera-negative patients from unnecessary chemotherapy while ensuring high-risk patients receive potentially life-saving treatment.
The GALAXY study's findings are groundbreaking for CRC management. The 10-fold survival advantage at 36 months based on ctDNA status is unprecedented. This far exceeds the prognostic value of current biomarkers. The study also validates ctDNA clearance as a surrogate endpoint for long-term outcomes, which could accelerate future clinical trials. Importantly, the data shows Signatera can identify patients who truly benefit from ACT, potentially changing treatment paradigms. The 100% 24-month survival for patients with sustained ctDNA clearance is particularly striking. This could lead to more personalized treatment strategies, potentially improving outcomes while reducing overtreatment in low-risk patients.
The GALAXY study results are highly positive for Natera (NASDAQ: NTRA). The data significantly strengthens Signatera's value proposition in the
- Potential for increased adoption and reimbursement of Signatera in CRC management
- Possible expansion into other cancer types, broadening Natera's market reach
- Enhanced competitive position against other liquid biopsy tests
The ability to predict chemotherapy benefit could lead to substantial healthcare cost savings, further driving adoption. With these results, Natera is well-positioned to capture a larger share of the growing precision oncology market, potentially boosting long-term revenue growth and profitability.
Shows nearly 10x advantage in overall survival at 36 months based on ctDNA status and affirms Signatera’s ability to predict chemotherapy benefit

This latest analysis, which will also be published in Nature Medicine on September 16, provides the first evidence of the ability of Signatera-based molecular residual disease (MRD) detection to predict overall survival (OS). The data also demonstrates Signatera’s ability to predict adjuvant chemotherapy (ACT) benefit in resectable CRC, with ctDNA clearance as an indicator of a superior survival benefit compared to no clearance.
In the study, 2,240 patients with stage II–IV CRC were monitored using Signatera after curative-intent surgery with a median follow-up of 23 months. Key takeaways include:
-
Signatera status was predictive of overall survival. Signatera-positivity in the post-op MRD window was found to be significantly associated with worse OS compared to Signatera-negative patients (HR: 9.68, p-value < 0.01) with a 36-month OS of
71.80% vs.96.0% , respectively. This 10x advantage in overall survival compares favorably to all known guideline-recommended biomarkers that have HRs for overall survival in a range of 1-4. -
Signatera status was predictive of an overall survival benefit from adjuvant chemotherapy.
-
High-risk stage II and stage III-IV patients who were Signatera-positive after surgery and received ACT demonstrated superior OS (adjusted HR: 0.53, p-value = 0.05), corresponding to a
50% reduction in the risk of death when treated with ACT. By comparison, the MOSAIC trial1, which was the last practice-changing study in adjuvant CRC, demonstrated a16% reduction in risk of death (HR: 0.84, p-value = 0.05). - Signatera-negative patients did not derive an OS benefit from ACT (adjusted HR: 0.53, p-value = 0.13).
-
High-risk stage II and stage III-IV patients who were Signatera-positive after surgery and received ACT demonstrated superior OS (adjusted HR: 0.53, p-value = 0.05), corresponding to a

Signatera status remained the most significant predictor of recurrence. Signatera-positivity after surgery was the single most significant prognostic factor associated with inferior DFS (HR 12.08, p-value <0.01) and OS (HR 9.87, p-value <0.01) in a multivariate analysis that included all clinicopathologic risk factors currently in use. This is also reflected by the 36-month DFS difference between Signatera-positive and Signatera-negative patients at
16.7% (95% CI: 12.1–21.9% ) versus83.5% (95% CI:81.2% –85.6% ), respectively. The association of Signatera-positivity with a significantly increased risk for recurrence was observed across all pathologic stages. -
Sustained Signatera clearance after ACT was associated with improved survival. Patients who clear ctDNA and remained Signatera-negative (referred to as “sustained clearance”) had superior survival benefit with 24-month OS of
100% . This compares to patients who cleared ctDNA for a period of time but later become Signatera-positive (referred to as “transient clearance”), with 24-month OS of82% , and patients who did not achieve ctDNA clearance, with 24-month OS of61% . This finding further supports the utility of sustained ctDNA clearance as a surrogate endpoint for long-term outcomes.
“We now have compelling prospective evidence from a large trial of more than 2,200 patients that clearly reinforces the link between MRD status and overall survival,” said Yoshiaki Nakamura, MD, PhD, co-author of the paper and principal investigator of the study from the National Cancer Center Hospital East in Kashiwa,
“The GALAXY data released today builds on an earlier analysis from the same study that was published in Nature Medicine in 2023,” said Minetta Liu, MD, chief medical officer of oncology at Natera. “Introducing 36-month, first-of-its-kind data on overall survival is an important milestone that reinforces the potential to improve outcomes for patients diagnosed with colorectal cancer. The updated data affirms ctDNA status as a critical measure both for prognosis and for predicting which patients may truly benefit from adjuvant chemotherapy.”
