GRAIL, Inc. is an American biotechnology company based in Menlo Park, California. It was previously a subsidiary of Illumina started as a startup seeking to develop an early cancer screening test for people who do not have symptoms. [3] Grail was spun-out from Illumina on June 24, 2024.
Their liquid biopsy (also called multi-cancer early detection test [4] ) was launched in June 2021 and is called the Galleri test. Promoted as groundbreaking, the test performed poorly in testing and Grail has subsequently faced discontent and legal action from investors claiming they have been misled about the test's potential. [5]
Illumina's own research showed that repeatedly sequencing DNA in the bloodstream made it possible to detect floating bits of DNA from cancer cells more accurately. [6] It initially aimed to recruit greater than 100,000 people into its clinical trials in order to accumulate the sizeable data required to detect and interpret cancer biomarkers. [7]
Grail calls its liquid biopsy for early cancer the Galleri test or the Galleri multi-cancer early detection (MCED) test, one of three multi-cancer screening tests which was under investigation as of November 2020. [8] [9]
Despite Grail promoting the test as a "groundbreaking and potentially life-saving advance", the results of early trials were poor. [5] A subsequent large-scale NHS England trial has been described by experts as overhyped and unethical. Grail is facing discontent and legal action from investors who suspect that its cancer testing claims misled them. [5]
Grail began as a San Francisco biotechnology and pharmaceutical startup company in 2015, the parent company being Illumina of San Diego, which produces most of the DNA sequencing machines that scientists use to study human biology and diagnose rare genetic diseases. [6] [10] [11] [12] Richard Klausner, then chief medical officer at Illumina and former director of the National Cancer Institute, advocated for the new business. According to the San Francisco Business Times, he correctly predicted how DNA sequencing technology would make it possible to detect evidence of a tumor from a blood sample. [13] He also joined Grail's board of directors. [14] According to Forbes in 2017, 20% of Grail's profits are kept by Illumina. [6]
In September 2020, Illumina announced an agreement to purchase Grail outright for $7.1 billion. [15]
On November 27, 2020, Grail announced a commercial partnership with the National Health Service (England) (NHS), to trial the Galleri test, reporting in 2026.
In March 2021, the Federal Trade Commission (FTC) sued to block the vertical merger. [16] [17] In September 2022, an administrative judge ruled against the FTC's position on antitrust grounds. [18]
In June 2023, Grail disclosed that letters were mailed to 408 patients incorrectly informing them that they may have cancer. The company blamed the incident on PWNHealth, saying that it was due to a software configuration issue, not due to incorrect Galleri test results. [19] [20]
In July 2023, it was reported that three separate lawsuits were filed against Grail by former female employees; the allegations included that Grail created a "frat house” culture and a “sexually charged, hostile work environment”. [21]
In October 2023, the European Commission ordered Grail to be divested from Illumina within the next twelve months. [22] The European Commission (EC) has since approved Illumina's divestment plan for separating from Grail. Illumina has set a goal of finalizing the divestment terms by the end of the second quarter of 2024. In April 2024, the EC approved Illumina's plan, allowing Illumina to explore either a trade sale or a capital markets transaction (spin-off) to divest Grail. In May 2024, Illumina publicly filed a Form 10 registration statement with the U.S. SEC, a necessary step for a potential capital markets separation of Grail. If a capital markets transaction occurs, Illumina must capitalize Grail with around $1 billion to fund 2.5 years of operations per the EC's divestment plan. [23] [24] [25] The spinoff was completed in June 2024, with Grail trading on the Nasdaq with ticker symbol GRAL and Illumina retaining a 14.5% share of Grail. [1]

Digital polymerase chain reaction is a biotechnological refinement of conventional polymerase chain reaction methods that can be used to directly quantify and clonally amplify nucleic acids strands including DNA, cDNA, or RNA. The key difference between dPCR and qPCR lies in the method of measuring nucleic acids amounts, with the former being a more precise method than PCR, though also more prone to error in the hands of inexperienced users. PCR carries out one reaction per single sample. dPCR also carries out a single reaction within a sample, however the sample is separated into a large number of partitions and the reaction is carried out in each partition individually. This separation allows a more reliable collection and sensitive measurement of nucleic acid amounts. The method has been demonstrated as useful for studying variations in gene sequences—such as copy number variants and point mutations.
Minimal residual disease (MRD), also known as Molecular residual disease, is the name given to small numbers of cancer cells that remain in a person either during or after treatment when the patient is in remission. Sensitive molecular tests are either in development or available to test for MRD. These can measure minute levels of cancer cells in tissue samples, sometimes as low as one cancer cell in a million normal cells, either using DNA, RNA or proteins.
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. In 2019, cancer was the second leading cause of death globally; more recent data is pending due to the COVID-19 pandemic.

Circulating tumor DNA (ctDNA) is tumor-derived fragmented DNA in the bloodstream that is not associated with cells. ctDNA should not be confused with cell-free DNA (cfDNA), a broader term which describes DNA that is freely circulating in the bloodstream, but is not necessarily of tumor origin. Because ctDNA may reflect the entire tumor genome, it has gained traction for its potential clinical utility; "liquid biopsies" in the form of blood draws may be taken at various time points to monitor tumor progression throughout the treatment regimen.
A liquid biopsy, also known as fluid biopsy or fluid phase biopsy, is the sampling and analysis of non-solid biological tissue, primarily blood. Like traditional biopsy, this type of technique is mainly used as a diagnostic and monitoring tool for diseases such as cancer, with the added benefit of being largely non-invasive. Liquid biopsies may also be used to validate the efficiency of a cancer treatment drug by taking multiple samples in the span of a few weeks. The technology may also prove beneficial for patients after treatment to monitor relapse.

Duplex sequencing is a library preparation and analysis method for next-generation sequencing (NGS) platforms that employs random tagging of double-stranded DNA to detect mutations with higher accuracy and lower error rates.
CAPP-Seq is a next-generation sequencing based method used to quantify circulating DNA in cancer (ctDNA). The method was introduced in 2014 by Ash Alizadeh and Maximilian Diehn’s laboratories at Stanford, as a tool for measuring Cell-free tumor DNA which is released from dead tumor cells into the blood and thus may reflect the entire tumor genome. This method can be generalized for any cancer type that is known to have recurrent mutations. CAPP-Seq can detect one molecule of mutant DNA in 10,000 molecules of healthy DNA. The original method was further refined in 2016 for ultra sensitive detection through integration of multiple error suppression strategies, termed integrated Digital Error Suppression (iDES). The use of ctDNA in this technique should not be confused with circulating tumor cells (CTCs); these are two different entities.
Circulating free DNA (cfDNA) (also known as cell-free DNA) are degraded DNA fragments released to body fluids such as blood plasma, urine, cerebrospinal fluid, etc. Typical sizes of cfDNA fragments reflect chromatosome particles (~165bp), as well as multiples of nucleosomes, which protect DNA from digestion by apoptotic nucleases. The term cfDNA can be used to describe various forms of DNA freely circulating in body fluids, including circulating tumor DNA (ctDNA), cell-free mitochondrial DNA (ccf mtDNA), cell-free fetal DNA (cffDNA) and donor-derived cell-free DNA (dd-cfDNA). Elevated levels of cfDNA are observed in cancer, especially in advanced disease. There is evidence that cfDNA becomes increasingly frequent in circulation with the onset of age. cfDNA has been shown to be a useful biomarker for a multitude of ailments other than cancer and fetal medicine. This includes but is not limited to trauma, sepsis, aseptic inflammation, myocardial infarction, stroke, transplantation, diabetes, and sickle cell disease. cfDNA is mostly a double-stranded extracellular molecule of DNA, consisting of small fragments (50 to 200 bp) and larger fragments (21 kb) and has been recognized as an accurate marker for the diagnosis of prostate cancer and breast cancer.
