\nGuardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today presented additional data from the ECLIPSE study at 2023 Digestive Disease Week (DDW) titled, \u201cClinical Validation of a Cell-Free DNA Blood-Based Test for Colorectal Cancer in an Average Risk Population\u201d (Abstract #913e) showcasing the performance of its blood-based technology to accurately detect early-stage colorectal cancer (CRC).<\/p>\n
\nThe ECLIPSE (Evaluation of ctDNA LUNAR Assay In an Average Patient Screening Episode) study is an over 20,000 patient registrational study evaluating the performance of the Shield blood test for detecting CRC in average-risk adults. The data presented at DDW elaborates on the top-line data the company announced in December 2022. Data presented today include:<\/p>\n
- \n
- \n83% sensitivity in detecting individuals with CRC;<\/p>\n<\/li>\n
- \n81% sensitivity in detecting Stages I-III;<\/p>\n<\/li>\n
- \n72% sensitivity in detecting localized disease (Stage I-II); and<\/p>\n<\/li>\n
- \nSensitivity by stage of 55% for Stage I, 100% for Stage II, 100% for Stage III, and 100% for Stage IV.<\/p>\n<\/li>\n<\/ul>\n
\nThese results are in range with other guideline recommended non-invasive screening modalities, where overall sensitivity ranges from 74-92%.<\/p>\n
\nThe ability to detect cancers in early stages is an important test parameter as the five-year survival rate is higher when caught early.1<\/sup> Shield\u2019s sensitivity of detecting stage I-III cases and localized cases (stage I-II) is in range with other guideline-recommended non-invasive screening modalities (FIT sensitivity in Stage I-III is 73%, and in localized cases is 70%).2<\/sup><\/p>\n
\n\u201cThere is a need for a more convenient and less invasive method to screen for colorectal cancer, and an accurate blood test has the potential to overcome many barriers patients face with traditional screening methods,” said Daniel Chung, MD, gastroenterologist at Massachusetts General Hospital and Professor of Medicine at Harvard Medical School. “The data presented today at DDW highlight the promising results for blood-based CRC screening and the potential for blood tests to help close the gap in screening adherence.”<\/p>\n
\nColorectal cancer is the third leading cause of cancer related death, but it is highly preventable and treatable if caught early.3<\/sup> Despite multiple screening modalities available for CRC, 49 million Americans remain unscreened.4<\/sup> Screening rates are even lower in minority and underserved populations.5<\/sup> This was a key consideration when conducting the ECLIPSE study, which reflects the diverse population of the U.S. Study data includes 13% Black, 15% Hispanic and 7% Asian American populations. Enrollment among Black Americans was above average for a clinical trial, which is important given the disproportionate impact of CRC on the black community.6<\/sup><\/p>\n
\n\u201cColorectal cancer screening saves lives, and yet, millions of people are still not getting it done. Blood tests have the potential to change that,\u201d said Michael Sapienza, chief executive officer of the Colorectal Cancer Alliance. \u201cOffering patients a convenient and minimally invasive option for getting screened that can reach them where they are is a great step forward in helping to close the screening gap.\u201d<\/p>\n
\nSince the commercial launch of the laboratory developed version of the Shield test in May 2022, it has shown an adherence rate greater than 90% in the real-world clinical setting.7<\/sup> Shield\u2019s performance in detecting CRCs, combined with this real-world adherence, suggests that Shield has the potential to detect more CRCs at a curable stage than traditional modalities.8,9,10<\/sup><\/p>\n
\n\u201cThere is an unmet need in CRC screening for a high-performance screening test that gets completed. The Shield test is spearheading a new patient-preferred category in CRC screening and has the potential to significantly increase overall screening rates,\u201d said AmirAli Talasaz, Guardant Health co-CEO. \u201cWe believe that as a longitudinal screening test, taken every three years, Shield would detect nearly all CRCs at a curable stage and will save many lives.\u201d<\/p>\n

About the Shield\u2122 Test<\/b><\/p>\n
\nThe Shield test detects colorectal cancer signals in the bloodstream from DNA that is shed by tumors, called circulating tumor DNA (ctDNA). Specifically, the test identifies specific characteristics of the DNA that may indicate the presence of cancer.<\/p>\n
\nShield is commercially available for eligible individuals by prescription only through healthcare professionals. This LDT (Laboratory Developed Test) is intended to be complementary to, and not a replacement for, current recommended CRC screening methods. A negative result does not rule out the presence of cancer. Patients with an abnormal blood-based screening result should be referred for a diagnostic colonoscopic evaluation.<\/p>\n
