In the flurry of presentations on early detection of cancer at the 2023 American Society of Clinical Oncology Annual Meeting, Grail LLC stood out for the number of sessions and the strength of its results. In a real-world study presented, Grail’s Galleri multi-cancer early detection (MCED) test cancer signal origin (CSO) demonstrated accuracy of 91%.
The 2023 American Society for Clinical Oncology Annual Meeting featured several notable developments on the diagnostics side, including significant advances in multi-cancer early detection (MCED). Grail Inc. presented its results from SYMPLIFY, the first major study of its MCED test in symptomatic patients. The test showed a negative predictive value of more than 97% and a positive predictive value that exceeded 75% in individuals who presented to primary care with non-specific symptoms that prompted a referral for cancer evaluation.
Burning Rock Biotech Ltd.’s share price flared up on Tuesday morning on news of U.S. FDA breakthrough device designation for its Overc multi-cancer detection blood test (MCDBT). The stock closed on Dec. 30, 2022, at $2.26 and rose sharply on the announcement to open at $2.89. By the end of the day, however, the stock had sunk to $2.15.
Some of the most exciting news out of the European Society for Medical Oncology Congress 2022 in Paris surrounded the rapidly evolving field of multi-cancer early detection (MCED), which offers the dual benefits of identifying malignancies at a more easily treated local stage and enabling screening for the 70% of cancers that lack recommended screening tests.
Thirteen months after Illumina Inc. and Grail Inc. merged, prior to regulatory approval, the deal has taken a turn for the worse. The prognosis looked better following an administrative law judge’s ruling Sept. 1 against the U.S. Federal Trade Commission’s lawsuit seeking to block the transaction, but the European Commission (EC) issued a decision Sept. 6 prohibiting the deal based on the likelihood that a merger would stifle innovation and limit choices in the early cancer detection liquid biopsy market.
The largest study to date assessing the use of cell-free DNA (cfDNA) analysis to detect cancer in advance of symptoms has completed enrollment of 140,000 healthy volunteers. The study, being run in the U.K. National Health Service (NHS) by the charity Cancer Research UK (CRUK) and cfDNA diagnostics specialist Grail Inc., is using Grail’s Galleri test to look for cancer-specific methylation patterns in blood.
Grail LLC reported a new study with the U.K.’s NHS to assess the clinical utility of its Galleri multi-cancer early detection test (MCED) for reducing late-stage cancer diagnoses. Menlo Park, Calif.-headquartered Grail presented the study design during the American Society of Clinical Oncology (ASCO) meeting in Chicago. The randomized controlled trial will enroll 140,000 asymptomatic participants aged 50-77 living across England to determine if Galleri can find cancers at an early stage when they are less advanced.
The U.S. Federal Trade Commission (FTC) is hardly alone in its antipathy toward Illumina Inc.'s acquisition of Grail Inc., and FTC attorney Susan Musser said Aug. 24 that Illumina’s dominance of the market for next-generation sequencing (NGS) is perhaps the key aspect of the FTC’s case. Musser invoked the wide number of companies that jumped into the fray to develop a vaccine for the COVID-19 pandemic as an illustration of the need to maintain competition in the multicancer testing space.
Grail Inc. reported on June 4 the first results of its Pathfinder study evaluating its assay for the early detection of 50 cancers, showing a positive predictive value of 44.6%. With a total of 6,629 study participants across more than 140 clinical study sites, the blood test is supported by what the health care company believes to be the “largest clinical study program in genomic medicine.”
Grail Inc. is teaming up with Quest Diagnostics Inc. to support the upcoming launch of its multicancer blood test. The early cancer detection test, called Galleri, is slated to begin rolling out in the second quarter of 2021. Quest’s 2,200 patient service centers and network of 5,000 mobile phlebotomists will help to collect blood samples for Galleri once the test becomes available in the U.S.
