GRAIL, which was reacquired by Illumina for $8 billion, inked a partnership earlier this year with pharmaceutical companies Amgen, AstraZeneca, and Bristol Myers Squibb.
The companies will soon begin using GRAIL’s technology to test promising new approaches for monitoring minimal residual disease and detection recurrence, and gain deeper insights into tumor biology and patient outcomes.
GRAIL also signed an agreement with the U.K. National Health Service (NHS) to support the NHS’ long-term plan for earlier cancer diagnoses in an effort to save lives.
The partnership program will reportedly involve approximately 165,000 people in the United Kingdom. It includes two groups.
The first will include 140,000 people over the age of 50 without any suspected cancer.
The second will include 25,000 people 40 and above with suspected signs or symptoms of cancer.
“Based on data from this U.K. program, access to the test could be expanded to around 1 million people across 2024 and 2025 and may roll out to a larger population thereafter,” said Ofman, who noted that Galleri is intended to be a complement to existing recommended screenings, not a replacement.
But, he said, “We believe Galleri has the opportunity to revolutionize cancer screening, potentially leading to reductions in the human and economic toll of cancer.”
In March, GRAIL announced that Providence, a leading regional health system based in Renton, Washington, will be the first U.S. health system to offer Galleri as a complement to single cancer screening tests.
The Galleri test initially will be used by Providence at its California, Washington, and Oregon points of care. It could eventually be available across Providence’s entire seven-state footprint.
That includes more than 50 hospitals and nearly 1,100 health clinics serving 5 million patients.
Dr. Amy Compton-Phillips, chief clinical officer at Providence, said the company will integrate the Galleri test into clinical care.
“When combined with the power of our genomics research, having a single blood test that can detect more than 50 cancers advances our goal of finding cancer early, enabling our providers to administer treatment when it’s most likely to be successful and giving our patients the opportunity to achieve the best possible outcomes,” she said in a press statement.
Hans Bishop, the former CEO of GRAIL, said in the statement in March 2021 that GRAIL’s partnership with Providence “moves us that much closer to making a tremendous and potentially life-altering difference for patients and providers.”
In addition, the test will be available by the end of this year in Mayo Clinic facilities in Rochester, Minnesota as well as Jacksonville, Florida, and Phoenix, Arizona.
People can request the test from their doctor. Health insurance, however, doesn’t yet cover it. People need to pay $949 out of pocket to cover it
Cancer is projected to become the world’s leading cause of death this year.
While the cancer death rate in the United States has declined, more than 600,000 Americans will die from cancer in 2021, according to the
This is largely because the majority of cancers are found at later stages when treatment may be more difficult.
“We’ve been waging a war against cancer for decades — from Richard Nixon’s declaration to the Biden Moonshot. But we are still not winning this war,” Ofman said.
“We are still diagnosing the disease far too late, when it’s in its metastatic state. Recommended screening tests save lives, but they only cover five cancer types and screen for a single cancer at a time.”
Ofman said that the cancers responsible for 71 percent of cancer deaths have no recommended early detection screening.
By adding Galleri to existing screening tests, Ofman noted, there’s the potential to reduce late-stage cancer diagnoses (stage 3 and 4) by two-thirds.
“This would translate to a reduction of 5-year cancer deaths by 39 percent among those detected earlier, equating to an overall reduction of all 5-year cancer deaths by 26 percent,” he said.
Historically, blood tests haven’t been the best way to detect cancer.
Even blood tests on people with blood cancers such as lymphoma and leukemia were ironically not the most effective way of determining whether a person has cancer.
But blood-testing technologies are now changing the way the disease is diagnosed and treated.
GRAIL’s technology is just the tip of the iceberg in terms of how genetics are revolutionizing cancer care.
In cancer biotech circles, the term “blood test” is out and the term “liquid biopsy” is in.
A liquid biopsy simply means an examination of cancer-related material (like DNA) from a blood sample.
Liquid biopsies haven’t yet replaced a tumor biopsy. But most people interviewed for this story agreed that liquid biopsies are showing great promise in facilitating individualized approaches to cancer treatment.
The Food and Drug Administration (FDA) approved two blood tests earlier this year that can help guide treatment decisions for people with cancer.
The tests, Guardant360 CDx and FoundationOne Liquid CDx, are made by different companies and were
Oncologists have historically based treatment decisions on features like the organ in which the cancer started growing, whether the cancer has spread, and whether the patient has other health conditions.
Now they often use genetic changes in the tumor, according to the
Certain targeted therapies and immunotherapies work best against tumors that have specific genetic changes.
The newly approved blood tests identify genetic changes, including mutations, by scanning DNA in the blood.
Analyzing genetic changes in a person’s cancer is called genomic profiling, tumor profiling, or tumor sequencing.
Both Guardant360 CDx and FoundationOne Liquid CDx are approved for people with any solid cancer (lung, prostate, etc.).
Most scientists interviewed by Healthline agreed that there’s great potential for Galleri and other next-generation blood-based tests to change the way cancer is diagnosed and treated.
“The ability to detect cancer before imaging or clinical exam is, as the namesake of this test suggests, one of the holy grails in cancer care,” Dr. Sandip Patel, a medical oncologist at Moores Cancer Center at UC San Diego, told Healthline.
Patel said that while there still needs to be more data collected from GRAIL’s Galleri test, “The promise of this approach is boundless, and we are just starting to see the potential in what over time will be an increasingly accurate test.”
Patel added that while the Galleri data on the false-positive rate of less than 1 percent is “very reassuring,” he agrees with GRAIL’s Ofman that Galleri should be used in addition to existing screening.
“It would be premature to stop approved screening paradigms,” Patel said.
Ofman said that the Galleri test is a direct descendant of the Human Genome Project, which ushered in the era of precision medicine 2 decades ago.
“Cancer is a disease of the genome,” Ofman posited.
“What this means is that cancer has specific genomic alterations — the DNA in the cancer cells carry cancer-specific signals.”
Tumors shed this DNA into the blood, Ofman explained.
“We now know that these DNA fragments and their cancer-specific signals can be detected to identify cancer from a simple blood draw,” he said.
When a cancer signal is detected, GRAIL’s blood test can determine where in the body the cancer is located with high accuracy, all from a single blood draw, Ofman said.
“Galleri could be one of the first examples of a technology derived from insights from the Human Genome Project to have an impact on the broader population level,” he said.
Ofman, a gastroenterologist and health services researcher at UCLA/Cedars-Sinai before joining Amgen, the drug company where he spent more than 15 years, said he came to GRAIL to help tackle one of healthcare’s greatest challenges:
Reducing deaths from cancer.
“The opportunity to make a major impact on public health by bringing innovation in genomics and AI [artificial intelligence] to improving early cancer detection to bend the cancer mortality curve drives my focused efforts every day,” he said.
“This is a once-in-a-lifetime opportunity to bring potentially life-altering innovative technology to patients.”
