Exact Sciences Showcases Breadth of Early Detection and Treatment Guidance Portfolio with Multiple Data Presentations at ASCO 2022

MADISON, Wis., May 27, 2022 /PRNewswire/ -- Exact Sciences Corp. (NASDAQ: EXAS), a leader in advanced cancer diagnostics, today announced new data supporting its cancer tests and treatment guidance tools will be showcased in nine poster presentations and five e-abstracts at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, being held June 3-7 in Chicago, Illinois.

"As the leading cause of death worldwide,¹ cancer creates tremendous human suffering and staggering health care costs. Tests to help catch the disease earlier and guide more effective treatment are necessary to improve outcomes," said Kevin Conroy, chairman and CEO of Exact Sciences. "Together with our collaborators from leading medical institutions, Exact Sciences is proud to present extensive data at this year's ASCO Annual Meeting. These presentations highlight the breadth of our pipeline and portfolio of tests as part of our relentless efforts to advance the field of cancer diagnostics."

Studies supporting Exact Sciences' screening and earlier detection efforts include a comparison of simulated outcomes between stool- and blood-based colorectal cancer screening tests. The modeled outcomes suggest blood-based tests result in detecting fewer colorectal cancer cases compared to stool-based tests due to differences in colorectal cancer sensitivity and specificity and lower advanced adenoma detection rates.² A cost-effectiveness analysis that assumed adherence to stool-based screening and/or follow-up colonoscopy increased when coinsurance was waived showed improvement in outcomes including life years gained and CRC incidence and mortality reductions.³ Another study indicated a shorter time to diagnosis for screenable versus symptom-driven cancers, supporting an expanded use of multi-cancer testing.⁴

Also being presented are findings from Mayo Clinic as part of the academic center's ongoing collaboration with Exact Sciences to advance the use of methylated DNA markers in detecting a range of cancer types, including cutaneous melanoma, prostate cancer, and lymphoma.⁵

Data highlighting Exact Sciences' precision oncology portfolio of tests will also be presented. The analyses support use of Oncomap™ and Oncomap™ ExTra, comprehensive genomic profiling tests formerly known as the Oncotype Map™ Pan-Cancer Tissue and GEM ExTra^® tests, respectively, to inform targeted therapy selection and clinical trial options for patients with advanced solid tumors.⁶ Also being presented is an overview of the ongoing CORRECT-MRD II study, designed to generate clinical validation data for the company's minimal residual disease assay in Stage II and III colorectal cancer patients.⁷

Following are details for the fourteen abstracts that have been accepted at the 2022 ASCO Annual Meeting. All abstracts are now available in the ASCO Meeting Library.
