Guardant Health presented results of largest study on ctDNA in colon cancer
Guardant Health (GH) presented results of the largest study to date evaluating circulating tumor DNA, ctDNA, in colon cancer prior to chemotherapy, demonstrating the ability of the Guardant Reveal test to stratify the risk of disease recurrence and overall survival, and thus inform treatment decisions after surgery. Data from the phase III trial of FOLFOX-based adjuvant chemotherapy involving over 2,000 patients with stage III colon cancer with median follow-up of 6.1 years were presented at the 2025 American Society for Clinical Oncology Annual Meeting. Results demonstrated that circulating tumor DNA detected in the bloodstream after cancer surgery and prior to the start of adjuvant therapy, using the Guardant Reveal test, is a strong predictor of the risk of disease recurrence and poorer survival, and suggest the potential for ctDNA testing to improve decision-making at a critical time point for post-operative chemotherapy. Specifically: Among patients with post-surgical ctDNA detected, 62.6% had the cancer return within 3 years, despite having had adjuvant chemotherapy, while only 15.4% of patients with undetectable ctDNA recurred in the same period. The level of ctDNA, or tumor fraction, showed promise in identifying individuals who are less likely to clear residual disease with adjuvant treatment.

In Largest Molecular Residual Disease (MRD) Study in Colon Cancer, Guardant Reveal Testing Prior to Chemotherapy Provides Robust Stratification for Risk of Disease Recurrence and Survival to Enable Timely Treatment Decisions
PALO ALTO, Calif.--(BUSINESS WIRE)--Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, and its research collaborators today presented results of the largest study to date evaluating circulating tumor DNA (ctDNA) in colon cancer prior to chemotherapy, demonstrating the ability of the Guardant Reveal™ test to stratify the risk of disease recurrence and overall survival, and thus inform treatment decisions after surgery. Data from the phase III trial of FOLFOX-based adjuvant chemotherapy (NCCTG N0147) involving over 2,000 patients with stage III colon cancer with median follow-up of 6.1 years were presented at the 2025 American Society for Clinical Oncology (ASCO) Annual Meeting. Results demonstrated that circulating tumor DNA detected in the bloodstream after cancer surgery and prior to the start of adjuvant therapy, using the Guardant Reveal test, is a strong predictor of the risk of disease recurrence and poorer survival, and suggest the potential for ctDNA testing to improve decision-making at a critical time point for post-operative chemotherapy. Specifically: Among patients with post-surgical ctDNA detected, 62.6% had the cancer return within 3 years, despite having had adjuvant chemotherapy, while only 15.4% of patients with undetectable ctDNA recurred in the same period. The level of ctDNA, or tumor fraction, showed promise in identifying individuals who are less likely to clear residual disease with adjuvant treatment. 'Thirty percent of patients with stage III colon cancer will relapse after surgery, despite having standard adjuvant chemotherapy,' said Frank Sinicrope, MD, professor of oncology and medicine at Mayo Clinic and principal investigator for the study. 'In this study, we demonstrate that analysis of postsurgical ctDNA can improve the prediction of disease recurrence over standard staging criteria, which may help guide patient management and follow-up. These data further support the routine use of ctDNA in management of stage III colon cancer patients.' 'With the Guardant Reveal test, a simple blood draw can be used to identify colorectal cancer patients who have molecular residual disease and are most likely to benefit from adjuvant therapy,' said Helmy Eltoukhy, Guardant Health chairman and co-CEO. 'This large study confirms the test's ability to identify high risk of cancer returning and support oncologists in making more informed therapeutic decisions to help improve patient outcomes.' The full abstract for the presentation can be found on the ASCO website. About Guardant Reveal Guardant Reveal, which runs on the Guardant Infinity™ smart liquid biopsy platform, is a blood test that uses epigenomic (methylation) analysis to detect circulating tumor DNA, a marker of minimal residual disease, to predict cancer recurrence, helping to guide clinical decisions after surgery or chemotherapy. The test is covered by Medicare for patients with colorectal cancer in the early post-surgical setting and for surveillance testing to monitor for disease recurrence after curative intent treatment. About Molecular Residual Disease Molecular residual disease refers to a subclinical measure of cancer burden that remains during and following treatment. A patient's MRD status is a reliable indicator of clinical outcome and response to therapy and can be used for risk stratification and to guide treatment options when used in conjunction with other clinical data.

Guardant Health, Pfizer Collaborate To Develop New Cancer Therapies Using Liquid Biopsy Platform
Guardant Health, Inc. (NASDAQ:GH) on Thursday announced a strategic collaboration with Pfizer, Inc. (NYSE:PFE) to support the development and commercialization of Pfizer's oncology portfolio using the Guardant Infinity smart liquid biopsy platform. Under the multi-year collaboration agreement, Guardant and Pfizer aim to: Utilize Guardant's portfolio of liquid biopsy tests in Pfizer's global clinical studies. Evaluate the clinical utility of (a) circulating tumor DNA (ctDNA) level as a surrogate endpoint to monitor therapy response and (b) related blood-based epigenomic analyses. Also Read: The collaboration will also allow Pfizer to access Guardant's liquid biopsy tests in China for its global clinical trials, which include China cohorts. In July 2022, Guardant announced a strategic partnership with Adicon Holdings Limited, an independent clinical laboratory company based in China, to offer Guardant tests to biopharmaceutical companies conducting clinical trials in China. In January, Guardant Health announced that Palmetto GBA, a Medicare administrative contractor that administers the Molecular Diagnostics Services program (MolDX), granted coverage for the Guardant Reveal test to monitor for disease recurrence in patients with colorectal cancer (CRC) following curative intent therapy. Guardant Reveal, which runs on Guardant's Smart Liquid Biopsy platform, is a blood test that uses epigenomic (methylation) analysis to detect circulating tumor DNA (ctDNA), a marker of minimal residual disease (MRD). This test predicts cancer recurrence, helping to guide clinical decisions after surgery or chemotherapy. Price Action: GH stock is up 2.59% at $46.82 at the last check Thursday.
