This study indicates Guardant Health’s blood test could provide meaningful clinical performance in an average risk screening population
Guardant Health, Inc. (Nasdaq: GH), presents data at the American College of Gastroenterology Annual Scientific Meeting being held from October 22-27, showing its LUNAR-2 blood test, which has been developed to screen average-risk patients for colorectal cancer (CRC), offers optimized sensitivity and specificity in identifying those with early-stage CRC. This study was selected by the ACG Abstract Selection Committee as the recipient of the International Award.
In the study, researchers evaluated the LUNAR-2 test in a cohort of 699 patients with early-stage (Stage 1, 2, or 3) CRC and found the test achieved an overall sensitivity of 96% in detecting CRC and 94% specificity. These findings are on par with other currently available modalities, such as stool-based screening.1 The limitation of this retrospective study is that the biobanked samples are from individuals with known CRC and 37% of cases had asymptomatic disease.
"We know that the earlier CRC is detected, the better a person’s chances are of surviving it," said Dr. Hee Cheol Kim, study investigator and Professor of Surgery at Samsung Medical Center in Seoul, South Korea. "The clinically meaningful sensitivity and specificity of the LUNAR-2 blood test in detecting CRC, most notably in people with early-stage disease, indicates that it could be a very useful tool in improving patient outcomes."
A further analysis showed that in patients with Stage 1 and 2 CRC, whereby blood-based detection can be especially challenging, the test offered 93% overall sensitivity. Additionally, the blood-based test identified 90% of patients with asymptomatic Stage 1 or 2 CRC, suggesting the test may have meaningful performance in an average-risk screening population. These findings need to get further validated in a registrational screening trial.
