Guardant Health Shield Platform Selected for Inclusion in National Cancer Institute's Vanguard Study to Evaluate Emerging Technologies for Multi-Cancer Detection

January 7, 2025

PALO ALTO, Calif.--(BUSINESS WIRE)-- Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced the National Cancer Institute (NCI) has selected the company's Shield™ multi-cancer detection (MCD) test for use in its Vanguard study, which will address the feasibility of using MCD tests in future clinical trials related to cancer screening. MCD tests are blood tests that can screen for several types of cancers simultaneously.

In February 2024, the National Institutes of Health (NIH) launched the Cancer Screening Research Network (CSRN), which is funded by the NCI, part of NIH, to evaluate emerging cancer screening technologies, including MCD tests. The network will support research to investigate how to identify and diagnose cancers earlier, when they may be easier to treat.

As an initial effort, CSRN is launching the Vanguard Study, a four-year pilot study that will enroll up to 24,000 people to inform the design of a much larger randomized controlled trial evaluating the use of MCD tests for cancer screening. In its studies, the network aims to reach diverse populations, including underserved populations, that are receiving routine care in a variety of health care settings.

"Despite recent advances in screening technology, there are still many types of cancer that are difficult to detect with existing technologies until the late stages, when they become much more challenging to treat," said AmirAli Talasaz, Guardant Health co-CEO. "We are excited about the potential for early detection of multiple cancers through a simple blood draw with our Shield MCD test. The Vanguard study is an important step in demonstrating the value of our technology."

Of the many companies whose tests were evaluated by NCI to be considered for inclusion in the Vanguard study, Guardant Health was selected to be one of two participants, based on the overall performance of its Shield platform. The NCI provided a blinded reference set to verify the platform's performance in detecting 10 cancer types, including lung, breast, colorectal, prostate, bladder, ovarian, pancreatic, esophageal, liver and gastric. Results from the NCI verification study are expected to be published in early 2025.
