ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation
Trial Status: active
The purpose of ORACLE is to demonstrate the ability of a novel ctDNA assay developed by
Guardant Health to detect recurrence in individuals treated for early-stage solid tumors.
It is necessary that ctDNA test results are linked to clinical outcomes in order to
demonstrate clinical validity for recurrence detection and explore its value in a
healthcare environment subject to cost containment.
