Today GRAIL announced a favorable vote from an FDA Advisory Committee for the approval of the Premarket Approval application of the Galleri multi-cancer early detection test (MCED). The Committee considered Galleri’s safety, effectiveness, and overall benefit-risk profile for screening for the early detection of multiple types of cancer in adults aged 50 years and older.

Full cohort results from GRAIL’s PATHFINDER 2 study have been published in @NatureMedicine, adding to the growing body of evidence supporting multi-cancer early detection (MCED) testing. Learn more: bit.ly/4y3psIK Rx Only. See Important Safety Information: bit.ly/411L6zk

Detailed peer-reviewed results from the NHS-Galleri trial are now published in @NEJM and @NatureMedicine, providing clinical utility and performance data. These results reflect GRAIL’s commitment to setting a high bar for MCED evidence—rigorously demonstrating Galleri’s potential to reduce late-stage diagnoses and find more cancers earlier. #EarlyCancerDetection #CancerScreening #MCED Learn more: New England Journal of Medicine: bit.ly/3Vbd5f8 Nature Medicine: bit.ly/4y9il1j Rx Only.

Greetings from Sunnyvale, California ☀️— GRAIL’s new HQ! We’re excited for this new chapter as we continue to work toward our mission to detect cancer early, when it can be cured.

Today GRAIL announced that the U.S. Food and Drug Administration’s (FDA) Molecular and Clinical Genetics Panel of the Medical Devices Advisory Committee is scheduled to meet on Sept. 23, 2026 to review the Premarket Approval (PMA) application for the Galleri® multi-cancer early detection (MCED) blood test.

Many cancers stay hidden until it is too late. When cancer is diagnosed after it has spread distantly, it is more difficult to treat and typically has worse outcomes. Diagnosing cancer before Stage IV can make a meaningful difference. For a growing number of cancers, treatment with curative intent may still be possible at Stage III. That’s why reducing Stage IV diagnoses remains such an important part of improving cancer outcomes. Learn more: grail.com #CancerScreening #EarlyCancerDetection

Melissa didn’t take a multi-cancer early detection (MCED) test once and leave it at that. She made MCED testing part of her annual health routine. The first year, the test did not detect a cancer signal. The second year, she received a Cancer Signal Detected result with a predicted origin of liver/bile ducts. Melissa felt healthy and had no symptoms. Follow up diagnostic testing confirmed Stage I bile duct cancer. Now she’s using her story to encourage others to keep cancer screening part of the conversation, year after year. #CancerScreening #EarlyCancerDetection #MCED The overall sensitivity in study participants with liver/bile duct cancer was 93.5% (100% for stage I, 70.0% stage II, 100% stage III, 100% stage IV).

“Early detection can save an awful lot of lives, I think I’m evidence of that.” Ann joined the NHS-Galleri trial evaluating a multi-cancer early detection (MCED) test hoping her participation might help others. She never imagined it would help her, too. Watch her story and learn more about the NHS-Galleri trial: bit.ly/4wY05Ij The overall sensitivity in study participants with colon/rectum cancer was 82% (43.3% for stage I, 85% stage II, 87.9% stage III, 95.3% stage IV).

Robert signed on for the NHS-Galleri trial with the intention of advancing cancer research. When the multi-cancer early detection (MCED) test returned a Cancer Signal Detected result, he was shocked. On the latest episode of The Cancer SIGNAL podcast, host Rayshawnda Madison speaks with Robert as he shares how his follow-up journey eventually led to an early HPV-related cancer diagnosis, what it was like to navigate treatment and recovery, and how the experience changed the way he thinks about health and early detection. The Cancer SIGNAL is available wherever you listen to podcasts. #EarlyCancerDetection #MCED #Podcast Apple Podcasts: bit.ly/4byN5jM Spotify: bit.ly/4bOp9I4 Transcripts & more episodes: grail.com/podcast/

Dr. Nima Nabavizadeh, principal investigator for the PATHFINDER 2 study, shares key takeaways from this data. He noted: “As an oncologist, I have seen too many patients diagnosed only after their cancer has spread, when treatment decisions become more difficult. By helping find more cancers earlier, when more treatment options may be available, there is great potential for multi-cancer early detection to transform cancer screening.” Find all of GRAIL’s data from #ASCO26 here: bit.ly/4wY05Ij RX Only.

When Doreen volunteered for the NHS-Galleri trial evaluating a multi-cancer early detection (#MCED) test, she never expected the study would identify a signal for #lymphoma in her own blood. Follow-up testing confirmed a Stage I-II lymphoma diagnosis and Doreen was able to promptly begin treatment. Today, she’s back on her bike and sharing her journey to help others understand the importance of #EarlyCancerDetection. See more about the NHS-Galleri trial: bit.ly/4wY05Ij #ASCO26 The overall sensitivity in study participants with lymphoma was 56.3% (27.3% for stage I, 58.3% stage II, 71.7% stage III, 60.9% stage IV).

Results from the NHS-Galleri trial presented at #ASCO26 found that the addition of the Galleri test to standard-of-care cancer screenings led to a four-fold increase in screen-detected cancers.
