• Modeling data show Cologuard Plus^TM test delivers highest life-years gained with fewest number of colonoscopies among noninvasive colorectal cancer (CRC) screening strategies
• Additional abstracts support real-world expertise and experience in increasing patient adherence, especially in underserved populations

MADISON, Wis. / Oct 27, 2024 / Business Wire / Exact Sciences Corp. (NASDAQ: EXAS), a leading provider of cancer screening and diagnostic tests, today announced the company will present modeling data evaluating the simulated benefit and burden of established CRC screening strategies, including the Cologuard Plus™ test during the American College of Gastroenterology (ACG) Annual Meeting. ACG takes place October 25-30, 2024, in Philadelphia, Pennsylvania. Exact Sciences will also present new data on improving adherence to help close the gap in CRC screening. ACG abstracts are available on the meeting website.

“Exact Sciences is pleased to share new modeling data which demonstrates the Cologuard Plus test as an efficient CRC screening strategy across modeled age ranges and screening intervals, given its high sensitivity and specificity for both cancer and precancer,” said Paul Limburg, MD, MPH, AGAF, chief medical officer for Screening, Exact Sciences. “The data demonstrate our commitment to continuous improvement and innovation to deliver best in class, patient-centric cancer screening and diagnostic solutions.”

Researchers used a validated simulation model to assess the benefit to burden ratio of the Cologuard Plus test and other established and emerging CRC screening options. Benefit was defined as life-years gained and burden as the lifetime number of colonoscopies.

The efficient frontier abstract summary and presentation details are as follows:

• Next Generation mt-sDNA Has the Best Balance Between Benefit and Burden of Age- and Interval-Recommended CRC Screening Among Stool- and Blood-Based Tests (P2119)
  • Summary: The next-generation mt-sDNA (ng-mt-sDNA) test was the only efficient non-invasive modality for screening over the guideline-recommended age interval of 45-75 years; Blood-based screening strategies were not efficient or near-efficient at any screening interval or age-range.
  • Session: Monday, October 28, 2024, 10:30 AM – 4:00 PM EDT

Increasing real-world adherence

The seven remaining abstracts share patient-centric research on improving CRC screening adherence rates, particularly in underserved populations. With industry-leading patient navigation and personalized outreach, these strategies directly impact millions of lives. When modeled against the U.S. general screening population, widespread implementation of the reported strategies could drive as much as a 10% reduction in the CRC screening gap.*

About the BLUE-C Study

BLUE-C was a multi-center, prospective study (NCT04144738) of more than 20,000 adults 40 years of age and older. The trial was designed to evaluate the performance of next-generation Cologuard (multi-target stool DNA or mt-sDNA). Using colonoscopy as a reference method, the robust study design compared next-generation Cologuard and a fecal immunochemical test (FIT). Blood samples were also collected for later evaluation of a blood-based screening test being developed by Exact Sciences. BLUE-C is one of the largest colorectal cancer screening trials ever conducted, and the study population reflects the racial and ethnic makeup of the United States according to the 2020 census.

About the Cologuard Plus™ test

Developed in collaboration with Mayo Clinic, the Cologuard Plus test features novel biomarkers and improved laboratory processes. It also incorporates enhanced sample stability components to provide patients more time to return their sample to Exact Sciences' lab and increase the valid result rate. Exact Sciences expects to launch the test with Medicare coverage and guideline inclusion in 2025.

About the Cologuard® Test

The Cologuard test is a first-line colorectal cancer screening test for use in adults age 45 or older who are at average risk for the disease. It is included in national colorectal cancer screening guidelines by the American Cancer Society (2018) and the U.S. Preventive Services Task Force (2021).

The Cologuard test revolutionized colorectal cancer screening by providing a best-in-class, noninvasive testing option for those at average risk. The test looks for certain DNA markers and blood in the stool that are associated with colorectal cancer and precancer and was shown to effectively detect colorectal cancer and precancer in the pivotal phase 3 DeeP-C study. The Cologuard test is easy to use. It can be completed at home and does not require any time off or special preparation. In the initial 10 years since launch, the Cologuard test was used more than 16 million times.

Important Information About the Cologuard Test

Do not use the Cologuard test if you have had precancer, have inflammatory bowel disease and certain hereditary syndromes, or have a personal or family history of colorectal cancer. The Cologuard test is not a replacement for colonoscopy in high-risk patients. The Cologuard test performance in adults ages 45-49 is estimated based on a large clinical study of patients 50 and older. The Cologuard test performance in repeat testing has not been evaluated.

The Cologuard test result should be interpreted with caution. A positive test result does not confirm the presence of cancer. Patients with a positive test result should be referred for colonoscopy. A negative test result does not confirm the absence of cancer. Patients with a negative test result should discuss with their doctor when they need to be tested again. Medicare and most major insurers cover the Cologuard test. For more information about the Cologuard test, visit Cologuard.com. Rx only.
