The COBRA study was designed to evaluate the effectiveness of using MRD testing to improve clinical outcomes in patients with stage II colon cancer after curative-intent surgery with a planned final readout in 2026.

"Our MRD test has great potential to help patients and their doctors stay ahead of cancer, and we remain confident about its promise to vastly improve patient care and its continued prospects for broad access and reimbursement," said Craig Eagle, MD, Guardant Health chief medical officer.

"We agree with the decision, based on the recent planned interim analysis, to close the COBRA study to new enrollees," said Dr. Eagle. "The field has progressed rapidly since the study was designed over four years ago, and since the study was initiated we have made tremendous progress with multiple upgrades of our MRD test. Additionally, we have many ongoing studies that will demonstrate the effectiveness of our current MRD tests in colorectal cancer and other settings."
