Harbinger Health presented clinical data at ASCO 2025 demonstrating their blood-based multi-cancer early detection test achieved 25.8% sensitivity for early-stage cancers and 80.3% for late-stage cancers at 98.3% specificity in high-risk populations.
The CORE-HH study enrolled 8,095 subjects from 126 U.S. sites, with the obesity cohort of 762 individuals showing the test's ability to detect cancers that disproportionately affect obese patients and lack established screening programs.
The company's ctDNA-methylation-based reflex testing system introduces a novel "intrinsic accuracy" metric of 36%, measuring the test's ability to correctly identify both cancer presence and tissue of origin.
In a modeled 100,000-person cohort, the test identified 51 of 86 pancreaticobiliary cancers, including 8 of 31 early-stage cases, addressing a critical gap for cancers without routine screening programs.
