Guardant Health Introduces Major Smart Liquid Biopsy Upgrade to Market-Leading Guardant360® Test, Further Extending Its Best-in-Class Performance

Running on Guardant Infinity™ smart liquid biopsy platform, new Guardant360 test covers over 10 times more genes, including all guideline-recommended genomic biomarkers across advanced solid tumors, and quantifies tumor burden with 10 times higher sensitivity
Upgraded test covered by Medicare and major private payers for comprehensive genomic profiling of all advanced solid tumors

Guardant Health, Inc. (NASDAQ:GH), a leading precision oncology company, today announced the launch of a major upgrade to its market-leading Guardant360 liquid biopsy test. The new enhanced test evaluates biomarkers in 739 genes in total, which is 10 times more cancer biomarkers than the previous version of Guardant360 evaluated. The test can also identify an extensive array of emerging biomarkers to precisely characterize cancer and can quantify disease burden at much higher sensitivity. The biomarkers, or gene alterations, detected by the test enable oncologists to identify the targeted treatment strategies that are most effective for patients with advanced cancer.

The expanded number of biomarkers identified by the upgraded Guardant360 test includes all guideline-recommended genomic biomarkers across advanced solid tumors and emerging biomarkers that may impact treatment planning in the future. The test runs on the Guardant Infinity smart liquid biopsy platform, which uses a novel genomic and epigenomic sequencing technology that provides exceptional sensitivity and accurately quantifies disease burden tumor fraction at 10 times lower levels than the previous version of Guardant360. Results are provided in 7 to 10 days.

“Guardant360 is the leading liquid biopsy test for patients with advanced cancer, and this major upgrade through our Guardant Infinity smart liquid biopsy platform enables us to give oncologists a much more complete view of cancer,” said Helmy Eltoukhy, Guardant Health chairman and co-CEO. “Our updated test provides much broader gene panel coverage and analyzes both currently actionable and emerging biomarkers not available on any other liquid biopsy test. This upgrade will mark the beginning of a new chapter of tumor profiling that will be as profound as the original introduction of comprehensive profiling, informing cancer care teams about the optimal treatment strategy for their patients by giving them many more precision treatment options that can help improve their outcomes.”

The updated Guardant360 test is covered for Medicare fee-for-service patients with advanced solid tumor cancers as a standalone service, based on coverage conveyed by Palmetto GBA, a Medicare administrative contractor for the Molecular Diagnostics Services program (MolDX®), under the existing local coverage determination. The test is also covered by all major insurers, representing over 300 million covered lives.

Guardant360 tests have been used by more than 15,000 oncologists and are widely accepted for blood-based comprehensive genomic profiling, with more than 500 peer-reviewed publications and over 500,000 tests performed to date.
