New Guardant Reveal™ data from interim analysis of COSMOS-CRC-01 demonstrates high performance for recurrence detection in early-stage colorectal cancer
REDWOOD CITY, Calif., January 19, 2022--(BUSINESS WIRE)--Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced it will present data highlighting the clinical utility of its liquid biopsy tests in the treatment and management of early- to late-stage gastrointestinal cancers, including colorectal cancer, at the 2022 ASCO Gastrointestinal Cancers Symposium being held January 20-22, 2022.
An interim analysis from COSMOS-CRC-01, a large, prospective, observational study, shows that the Guardant Reveal™ liquid biopsy test, when performed after curative intent surgery for stage II-III colorectal cancer, can detect molecular residual disease (MRD) prior to disease recurrence with an average lead time of greater than six months. The test integrates genomic and epigenomic signatures to detect disease without the need for tumor tissue. (Abstract 168)
Additionally, clinical utility data will demonstrate that the Guardant360® liquid biopsy test detects microsatellite instability-high (MSI-H) status in patients with advanced gastrointestinal cancers at a similar frequency to tissue-based testing1,2. MSI-H is an important biomarker used to predict response to immunotherapy. Also, real-world clinical outcomes data from the GuardantINFORM™ platform showed that colorectal cancer patients who received immune checkpoint blockade therapy after MSI-H status identification with Guardant360 achieved responses in line with published data in previously treated MSI-H advanced gastrointestinal cancers1,2. (Abstract 56)
"These studies further demonstrate the significant clinical value that our blood tests offer in detecting and monitoring cancer, which can help physicians make informed treatment decisions in patients with early- or late-stage gastrointestinal cancer without the need for an invasive tissue biopsy," said Helmy Eltoukhy, Guardant Health co-CEO. "Tissue biopsies can be difficult to obtain, time-consuming, and lead to complications, all of which can delay a patient’s treatment. Our blood-based tests can overcome these barriers and provide fast and actionable information to help guide treatment decisions across the continuum of care."

About the Guardant360 Liquid Biopsy Test
The Guardant360 liquid biopsy test is part of the market-leading Guardant360 portfolio that offers oncologists end-to-end testing solutions from treatment selection to treatment response monitoring. Since it was first introduced, the Guardant360 blood test has become widely accepted for blood-based comprehensive genomic profiling (CGP) with more than 260 peer-reviewed publications including over 80 clinical outcomes studies. It has been trusted by more than 11,000 oncologists with more than 250,000 tests performed to date.
The GuardantINFORM clinical-genomic platform is intended to help accelerate research and development of the next generation of cancer therapeutics by offering biopharma partners an in-silico platform that combines de-identified longitudinal clinical information and genomic data collected from the Guardant360 liquid biopsy test. With data from more than 160,000 patients diagnosed with locally advanced and metastatic cancers, this robust dataset offers real-world insights into anti-cancer therapy use in the clinic, tumor evolution, and treatment resistance throughout each patient’s treatment journey for many advanced solid tumor cancers, including non-small cell lung, breast, colon, and prostate.
About Guardant Reveal
Guardant Reveal test the first blood-only test that detects residual and recurrent disease in patients with Stage II and III CRC in under two weeks without the need for a tissue biopsy. The test detects ctDNA in blood after surgery to identify patients with residual disease who may benefit most from adjunctive therapy, and to monitor for recurrence of CRC in previously diagnosed patients.
