Natera Announces New MRD Data in Multiple Tumor Types, to be Presented at ASCO Annual Meeting

Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and genetic testing, today announced that the company, along with its collaborators, will present new data at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting taking place May 31 – June 4, 2024.

The presentations feature data across a variety of indications, including breast cancer, colorectal cancer (CRC), lung cancer, melanoma, esophageal cancer, and urothelial cancer, with one oral presentation and 12 poster presentations on Signatera™, Natera’s personalized and tumor-informed molecular residual disease test, as well as one poster with data on Empower™, Natera’s test for hereditary cancer.

Minetta Liu, MD, chief medical officer of oncology at Natera, said, “We look forward to sharing new data across cancer types, reflecting Natera's deep clinical pipeline in MRD with results from randomized trials as well as real-world studies. This includes promising new findings from the CIRCULATE-Japan GALAXY study demonstrating the prognostic and predictive utility of Signatera and actionable biomarkers in colorectal cancer.”

GALAXY is part of the CIRCULATE-Japan trial platform, which also includes ALTAIR, a first-of-its-kind, “treat on molecular recurrence” study evaluating the utility of Signatera in CRC. Natera expects to announce topline results for this phase III randomized trial in August 2024.

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 60 peer-reviewed papers.
