MADISON, Wis., May 22, 2025 – Exact Sciences Corp. (NASDAQ: EXAS), a leading provider of cancer screening and diagnostic tests, today announced it will present ten abstracts at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 30–June 3, 2025, in Chicago, Ill. Presentations include new data on the Oncodetect™ molecular residual disease (MRD) test, multi-cancer early detection (MCED) testing, the Oncotype DX Breast Recurrence Score^® test, and the Cologuard^® test that underscore Exact Sciences’ expanding portfolio and commitment to advancing care through scientific excellence.

“The data Exact Sciences will present at ASCO 2025 reflect the scientific rigor and clinical significance of our expanding portfolio and pipeline,” said Dr. Rick Baehner, MD, chief medical officer, Precision Oncology at Exact Sciences. “From MRD to MCED to CRC screening, we are advancing evidence-based innovations that help empower providers and deliver crucial answers to patients. Every study, partnership, and data point move us closer to a future where cancer is detected earlier and treated with greater precision.”

Real-world evidence supporting the Cologuard test continues to grow, with ongoing research into repeat screening. New data from prominent experts and research groups reinforce the Oncotype DX^® test as a trusted, evidence-backed tool, further affirming its role as the standard of care for predicting chemotherapy benefit for breast cancer patients. Building on more than a decade of experience with Cologuard and 20 years of leadership with the Oncotype DX test, Exact Sciences continues to advance the future of precision oncology and multi-cancer screening.

New Data and Continuous Evidence Generation Underscore the Oncodetect Test’s Power to Detect Cancer Recurrence. Data from the Beta-CORRECT study further strengthens the clinical foundation of the Oncodetect test, confirming its role in helping guide treatment decisions and surveillance strategies for patients with stage II–IV colorectal cancer¹. Expanding on this evidence to multiple solid tumor types, Exact Sciences and Flatiron Health continue enrollment in a multi-year, prospective study evaluating how MRD testing can improve cancer monitoring and treatment decisions in community care settings.

New Data Support Promise of MCED as Exact Sciences Prepares for LDT Launch. A modeling study found annual MCED testing could reduce late-stage cancer incidence by more than 40% and mortality by up to 18% in high-risk groups². Additionally, the Falcon registry, a large, prospective real-world study of Exact Sciences’ MCED test, will track 25,000 participants against a 50,000-person standard-care cohort to assess adoption, outcomes, and patient experience. These findings come as Exact Sciences prepares to launch Cancerguard™ EX, its MCED lab-developed test (LDT), in the second half of the year, marking a significant step in expanding access to earlier cancer detection.
