MADISON, Wis., May 21, 2021 /PRNewswire/ -- Exact Sciences Corp. (NASDAQ: EXAS) today highlights data from one oral and one poster presentation being featured at the 2021 Digestive Disease Week^® (DDW^®) virtual annual meeting, taking place May 21-23.

Notably, the poster shares data that incorporate real-world patient adherence rates into a colorectal cancer (CRC) microsimulation model. The data showed that Cologuard^® (mt-sDNA) was cost effective and provided the greatest reduction in CRC incidence and mortality versus annual fecal immunochemical test (FIT) and annual fecal occult blood test (FOBT) in a representative Medicare population.

Additionally, the oral presentation reports data from the New Hampshire Colonoscopy Registry to compare FIT and Cologuard outcomes in clinical practice. In follow-up colonoscopies performed after a positive stool test result, Cologuard was more likely to predict neoplasia than FIT, largely due to an increased detection of serrated polyps.

Colorectal cancer is the second deadliest cancer impacting both men and women in the U.S. It's also preventable if caught in early stages when it is more treatable.ⁱThe disease has been on the rise in younger adults and approximately 44 million average-risk people in the United States remain unscreened.ⁱⁱ

The abstracts are now available on the DDW website. Included below are titles, abstract numbers, and a summary of each abstract.

Cost-Effectiveness of Stool-Based Colorectal Cancer Screening Using Reported Real-World Adherence Rates in a Medicare Population
Abstract Number: Su053

The impact of real-world adherence rates on the cost-effectiveness of specific CRC screening strategies has been unclear. This study used the CRC-AIM microsimulation modeling platform to estimate the cost-effectiveness of stool-based screening strategies using test-specific, real-world adherence data. The analysis found that Cologuard was cost effective and demonstrated the greatest reduction in CRC incidence and mortality versus FIT and FOBT.

The results from the analysis were also published online in the Journal of Medical Economics.

Comparison of Colonoscopy Findings in Patients with Preceding FIT Positive and mt-sDNA Positive Tests to Patients Having Colonoscopy Only: Data From the New Hampshire Colonoscopy Registry
Abstract Number: 886

There are few comparisons of FIT and Cologuard screening test outcomes in clinical practice. Using the New Hampshire Colonoscopy Registry (NHCR), a comprehensive statewide population-based colonoscopy database, the diagnostic yield of colorectal neoplasia in follow-up colonoscopies in patients with a previous positive FIT, Cologuard, or screening colonoscopy were compared. After follow-up colonoscopy, 1.7% of patients with a positive Cologuard test, 1.6% of patients with positive FIT and 0.3% of patients who underwent screening colonoscopy had adenocarcinoma/colorectal cancer. At follow-up colonoscopy, Cologuard tests were more likely to predict neoplasia than either FIT positivity or screening colonoscopy, largely due to an increased yield of serrated polyps.

About Cologuard
Cologuard was approved by the FDA in August 2014, and results from Exact Sciences' prospective 90-site, point-in-time, 10,000-patient pivotal trial in adults 50 years of age or older were published in the New England Journal of Medicine in March 2014. Cologuard is included in the American Cancer Society's (2018) colorectal cancer screening guidelines and the recommendations of the U.S. Preventive Services Task Force (2016) and National Comprehensive Cancer Network (2016). Cologuard is indicated to screen adults 45 years of age and older who are at average risk for colorectal cancer by detecting certain DNA markers and blood in the stool. Do not use Cologuard if you have had precancer, have inflammatory bowel disease and certain hereditary syndromes, or have a personal or family history of colorectal cancer. Cologuard is not a replacement for colonoscopy in high risk patients. Cologuard performance in adults ages 45-49 is estimated based on a large clinical study of patients 50 and older. Cologuard 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 diagnostic 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 Cologuard. For more information about Cologuard, visit www.cologuard.com. Rx Only.
