GRAIL to Present New Multi-Cancer Early Detection Data at the 2023 ASCO Annual Meeting

Data Include Interim Results From the SYMPLIFY Study Evaluating GRAIL’s Multi-Cancer Early Detection Test in Symptomatic Patients Referred for Cancer Suspicion

Clinical and Real-World Experience Analyses Highlight Performance and Implementation of the Galleri® Multi-Cancer Early Detection Test

MENLO PARK, Calif.–(BUSINESS WIRE)–GRAIL, LLC, a healthcare company whose mission is to detect cancer early when it can be cured, will present new data evaluating the use and potential of its methylation-based multi-cancer early detection (MCED) platform at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, June 2-6. Presentations include interim results from SYMPLIFY, the first large-scale prospective study to evaluate GRAIL’s MCED test in symptomatic patients referred for cancer suspicion, as well as Galleri® real-world clinical surveillance data and subset analyses from the PATHFINDER clinical implementation study. An evaluation of Galleri implementation using a centralized model within Mercy’s multi-state health system will also be presented.

“If we hope to bend the cancer mortality curve, we need a new, population-scale approach for screening people that finds many more cancers than we do today, in earlier stages when treatments are often more effective,” said Josh Ofman, MD, MSHS, president at GRAIL. “We believe that adding multi-cancer early detection testing to recommended screening is the best chance to address the growing burden of late-stage cancer in an aging population. We are excited to present new data at this year’s ASCO Annual Meeting supporting the use of GRAIL’s MCED technology in adults at elevated risk of cancer, as well as initial findings from SYMPLIFY, a study evaluating patients presenting with signs and symptoms who are referred for a cancer evaluation.”

Initial results from SYMPLIFY will be presented during an oral session. SYMPLIFY is the first prospective study assessing the clinical performance of GRAIL’s MCED Methylation Platform in individuals with signs and symptoms that may indicate cancer. Researchers will also present an analysis of the early real-world clinical experience using the Galleri MCED test to detect a shared cancer signal and predict cancer signal of origin (CSO) to guide targeted diagnostic workup. Additionally, doctors from Mercy will present a preliminary analysis of an MCED test implementation model within a large health system utilizing a patient navigation system. A follow-up analysis to the PATHFINDER study assessing clinical implementation of the test following a cancer signal detected result and CSO-guided workups will also be presented. Results from the PATHFINDER study were previously reported during the European Society for Medical Oncology (ESMO) Congress 2022.

Abstracts will be available on the 2023 ASCO Annual Meeting website. Updated analyses will be presented at the Annual Meeting.

About Galleri®

Galleri is the first-of-its-kind multi-cancer early detection (MCED) test, which can detect a shared cancer signal across more than 50 types of cancer through a routine blood draw. The Galleri test can improve the opportunity for asymptomatic early detection by screening for multiple cancers, most of which lack recommended screening tests. Supported by robust clinical evidence, it has demonstrated a low false positive rate and high positive predictive value (the proportion of people with a positive screening result who are diagnosed with cancer) in asymptomatic people at an elevated risk for cancer.

The Galleri test uses next-generation sequencing and machine-learning algorithms to isolate cell-free DNA and analyze its methylation patterns to detect if a cancer signal is present. If a cancer signal is detected, the Galleri test predicts the cancer signal origin, or the tissue or organ where the cancer signal originated, to help guide diagnostic evaluation.

The Galleri test requires a prescription from a licensed health care provider and should be used in addition to recommended cancer screenings such as mammography, colonoscopy, prostate-specific antigen (PSA) test, or cervical cancer screening. It is intended for use in people with an elevated risk of cancer, such as those aged 50 or older.

Important Galleri Safety Information

The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those aged 50 or older. The Galleri test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. Galleri is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.

Results should be interpreted by a healthcare provider in the context of medical history, clinical signs and symptoms. A test result of “Cancer Signal Not Detected” does not rule out cancer. A test result of “Cancer Signal Detected” requires confirmatory diagnostic evaluation by medically established procedures (e.g., imaging) to confirm cancer.

If cancer is not confirmed with further testing, it could mean that cancer is not present or testing was insufficient to detect cancer, including due to the cancer being located in a different part of the body. False-positive (a cancer signal detected when cancer is not present) and false-negative (a cancer signal not detected when cancer is present) test results do occur. Rx only.

Laboratory/Test Information

GRAIL’s clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists. The Galleri test was developed, and its performance characteristics were determined by GRAIL. The Galleri test has not been cleared or approved by the U.S. Food and Drug Administration. GRAIL’s clinical laboratory is regulated under CLIA to perform high-complexity testing. The Galleri test is intended for clinical purposes.
