Natera, Inc. announced data from a colorectal cancer (CRC) study of its tissue-free Latitude MRD assay, which were presented at the 2025 European Society for Medical Oncology GI Congress (ESMO GI). The clinical performance of the assay was analyzed in a cohort of ~200 patients (>1,300 plasma samples) with resectable stage I-IV colorectal cancer. Samples were derived from the GALAXY arm of the CIRCULATE-Japan study, one of the largest and most comprehensive prospective studies of MRD testing in resectable CRC.

Key results include: Excellent clinical sensitivity to recurrence: The Latitude assay detected recurrence with 58% sensitivity in the post-surgical MRD window and 81% sensitivity in the surveillance setting, with median diagnostic lead time of 4.6 months. High clinical specificity: In the surveillance setting, patient-level specificity was 92%, and sample-level specificity was 97%. Highly prognostic of recurrence risk: MRD positivity was significantly associated with inferior outcomes during both the MRD (HR: 10, p Among high-risk stage II and stage III patients, those who were MRD-positive after surgery derived significant benefit from ACT (p;MRD = Molecular residual disease.
