Detecting Cancer Early, When It Can Be Cured

As a healthcare company with a mission to detect cancer early, when it can be cured, GRAIL seeks to not only transform cancer detection, but to utilize our proprietary technology platform to revolutionize healthcare more broadly.

Early Cancer Detection Shows Promise

Today, cancer is a leading cause of death worldwide. That’s in large part because there is no screening available for the vast majority of life-threatening cancers, and as a result, most cancers are detected too late when outcomes are often fatal.

Guideline recommended screening tests save lives, but they cover just five cancers and each one screens for a single cancer at a time. Cancers responsible for approximately two-thirds of cancer deaths have no recommended early detection screening.

Multi-cancer early detection (MCED) is one of the most promising new tools we have in the war on cancer. Recent next-generation sequencing and machine learning advances have enabled the development of multi-cancer early detection tests – single tests that can identify a signal for many cancers from a single blood draw.

Multi-cancer early detection blood tests analyze DNA that has been shed by all cells, including cancer cells, into the bloodstream, looking for abnormal methylation patterns on those cell-free DNA fragments that indicate the presence of cancer. The test can also accurately predict the part of the body from which that cancer originated.

Patients with cancer are not statistics. They’re real people with hope for the future. GRAIL is working to back up that hope with commercially-available solutions.

The Promise of a Better Future

Recent research shows that adding annual testing with multi-cancer early detection blood tests to the currently recommended screening tests may shift cancers that can be detected to earlier stages, and over five years may lead to a 39 percent reduction in cancer deaths for cancers that can be detected (or an approximate 26 percent reduction in overall cancer deaths).

GRAIL’s first product, the Galleri® test, is a groundbreaking multi-cancer early detection blood test with the potential to help save lives and transform cancer care by detecting a common cancer signal across more than 50 types of cancer, over 45 of which have no recommended screening today. Using the Galleri test as a complement to recommended screenings has the potential to make a tremendous, positive impact on public health.

Overview of Studies

With the target of ~335,000 participants and counting, our studies aim to develop, validate, and demonstrate the broad applicability of GRAIL’s multi-cancer early detection technologies. As part of our efforts, GRAIL has partnered with leading community and academic medical centers around the globe.

Our data set grows with each MCED test that we process, along with additional clinical trials and studies. To date, the database has exceeded over 12 PB (petabytes) – and it has the potential to grow in orders of magnitude.

Our Rigorous Approach to Transforming Cancer Care
GRAIL is working to develop new technologies for early cancer detection using the power of next-generation sequencing (NGS), along with population-scale clinical studies and state-of-the-art computer and data science. Our rigorous approach is exactly what it will take to transform cancer care.
Our foundational study, the Circulating Cell-free Genome Atlas Study (CCGA) (clinicaltrials.gov), was designed to develop, train, and validate a cell-free DNA-based MCED test. CCGA began enrolling in August 2016 and enrolled more than 15,000 participants.
Our STRIVE Study(clinicaltrials.gov)was designed to clinically validate our test in women not known to have cancer. STRIVE enrolled approximately 100,000 participants and the study is expected to be completed in May 2025.
Our SUMMIT Study (clinicaltrials.gov)was designed to clinically validate our test in individuals at high-risk levels for lung cancer. SUMMIT enrolled approximately 13,000 participants. A 24-month follow up is ongoing through 2023, with completion anticipated in 2030.
Our PATHFINDER Study (clinicaltrials.gov) was designed to assess the clinical implementation of our MCED test. PATHFINDER enrolled 6,662 participants. A 12-month follow up is ongoing.
The NHS-Galleri Trial aims to confirm Galleri’s clinical and economic performance in England’s NHS system as a precursor to its routine use. Approximately 140,000 participants will enroll. Initial results of the study are expected by 2023.
Our REFLECTION Study (clinicaltrials.gov)was designed to accumulate and study real-world data about the long-term efficacy and benefits of the test. REFLECTION will follow approximately 35,000 individuals who take the Galleri test over five years. Initial results of the study are expected by 2028.
Our PATHFINDER 2 Study(clinicaltrials.gov) was designed to evaluate the safety and performance of our test. Approximately 20,000 eligible participants will enroll over 10 months at up to 40 clinical institutions. Participants will be actively followed for approximately 3 years.

What if You Found Cancer Early Enough to Make a Difference?

Today, many cancers are found too late, when outcomes are often deadly. Multi-cancer early detection enables you to proactively test for many cancers, increasing the chances of finding cancer early. Finding cancer early is important to improve treatment outcomes and survival. The vast majority of cancers show no symptoms until later stages, when treatment options may be limited.
