New Study Published in ESMO Open Highlights Guardant Reveal's Performance in Detecting Minimal Residual Disease in Patients with Early-Stage Breast Cancer
LIBERATE Study: Guardant Reveal showed high sensitivity and 100% positive predictive value for relapse PALO ALTO, Calif., June 09, 2025--(BUSINESS WIRE)--Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced results from the LIBERATE study published in ESMO Open. The results in the peer-reviewed manuscript demonstrate the clinical validity and high performance of Guardant Reveal, the company's minimal residual disease (MRD) blood test, in predicting recurrence in patients with early-stage breast cancer. Guardant Reveal uses epigenomic (methylation) analysis to detect circulating tumor DNA (ctDNA) in a patient's blood without the need for a tissue sample. The LIBERATE study retrospectively analyzed 290 blood samples from 95 patients who were diagnosed with early-stage ER+/HER2- or triple negative breast cancer undergoing chemotherapy prior to surgery, half of whom had localized disease with no lymph node involvement. Nearly 40% had minimal or no residual tumor by pathologic assessment following neoadjuvant chemotherapy. Key findings include: High Sensitivity and Specificity: Guardant Reveal demonstrated 100% sensitivity for distant recurrence in patients with ER+/HER2- breast cancer (which represents about 70% of all breast cancers), and 71% overall, with 100% specificity and 100% positive predictive value for relapse. Significant Prognostic Power: Detection of ctDNA post-operatively was significantly prognostic for event-free survival (EFS), with median lead time of 152 days (range: 15-748 days) ahead of clinical recurrence (P < 0.0001). Nearly 100% of All Samples Evaluable: All patients with post-operative blood samples had MRD results available from Reveal, highlighting the power of a tissue-free MRD test among patients receiving neoadjuvant therapy, particularly the large percentage who have minimal to no tumor found at surgery. "This study underscores the clinical validity, robust prognostic value and high specificity of Guardant Reveal in identifying breast cancer patients at elevated risk of recurrence without the need for a tissue sample," said Craig Eagle, M.D., Guardant Health chief medical officer. "These findings reinforce the critical role Reveal can achieve in clinical decision-making, potentially transforming neoadjuvant and post-treatment surveillance strategies and improving patient outcomes." This publication adds to the growing body of evidence of Reveal's strong performance in early-stage breast cancer. Earlier this year, a peer-reviewed publication in Clinical Cancer Research focused on stage II and III triple negative breast cancer demonstrated 83% sensitivity for metastatic recurrence and 99.5% sample-level specificity. Post-surgical ctDNA detection was prognostic for shorter recurrence-free interval (P < 0.0001). Additionally, ctDNA detection at the post-neoadjuvant, presurgical time point was associated with a shorter recurrence-free interval in patients with residual disease at surgery (P < 0.0001).

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.
