Brief Title: ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation

ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation


  • Org Study ID: 02-MX-003
  • Secondary ID: N/A
  • NCT ID: NCT05059444
  • Sponsor: Guardant Health, Inc.


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.
