On July 15, 2025 Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, reported that patient enrollment has begun in the National Cancer Institute (NCI)’s Vanguard Study to evaluate emerging multi-cancer detection (MCD) technology (Press release, Guardant Health, JUL 15, 2025, View Source [SID1234654394]). Guardant’s Shield MCD test was selected for use in the four-year study, which aims to enroll up to 24,000 patients and evaluate the use of MCD tests—blood tests that can screen for several types of cancer simultaneously—in future randomized controlled trials.

Guardant’s Shield MCD test was chosen for the study based on the overall performance of its Shield platform in detecting 10 cancer types, including lung, breast, colorectal, prostate, bladder, ovarian, pancreatic, esophageal, liver and gastric. The data were presented at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago. The Vanguard study was initiated following review and approval by the U.S. Food and Drug Administration (FDA) as part of the NCI’s submission for an investigational device exemption (IDE).
"New screening technology like the Shield MCD test has the potential to detect multiple cancers earlier through a simple blood draw," said Craig Eagle, MD, Guardant Health Global Chief Medical Officer. "The earlier we can screen and diagnose cancers, the more options we can bring to patients and ultimately the more lives we can save. The Vanguard Study is a critical step in research to evaluate the role of this breakthrough technology in helping reduce cancer deaths."
The Vanguard Study, conducted by the Cancer Screening Research, a new NCI-sponsored clinical trials network, is enrolling individuals ages 45-75 who do not currently have cancer and who have not received a cancer diagnosis in the past five years. All participants will be offered standard cancer screenings as part of their care. Results from the study will inform the design of a much larger randomized controlled trial to evaluate the use of MCD tests for cancer screening.
"Initiation of the Vanguard Study is an exciting milestone, as we look to evaluate a new way to screen for cancer," said Scott Ramsey, M.D., Ph.D., director of the Hutchinson Institute for Cancer Outcomes Research at Fred Hutch Cancer Center and principal investigator for the Vanguard Study. "The study will help us learn more about multi-cancer detection tests and assess whether they can help people from all backgrounds find cancer early, when it may be easier to treat."
The Shield MCD test recently received Breakthrough Device Designation from the FDA for the multi-cancer screening of multiple cancer types including bladder, colorectal, esophageal, gastric, liver, lung, ovarian and pancreas cancer in individuals aged 45 or older who are at typical average risk for cancer. The FDA grants Breakthrough Device designation to a limited set of qualifying devices that have the potential to provide more effective treatment or diagnosis of life-threatening diseases, such as cancer, than current options. The goal of the FDA’s Breakthrough Devices Program is to provide patients and healthcare providers with timely access to medical devices by speeding up their development, assessment and review.
