ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation

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.

Cohort 2A: Resectable OR Cohort 2B: Unresectable,

  • Cohort 3: Invasive breast carcinoma with hormone receptor (e.g. estrogen receptor (ER) and progesterone receptor (PR) expression) and human epidermal growth factor receptor 2 (HER2) status known and one the following:

Cohort 3A: High-risk2 HER2+ breast cancer (any ER, PR status allowed) OR Cohort 3B: High-risk2 triple negative breast cancer (TNBC) OR Cohort 3C: High-risk3 HR-positive/HER2-negative invasive breast carcinoma,

  • Cohort 4: Stage IIB-III cutaneous melanoma or limited (resectable) stage IV melanoma treated with curative intent,
  • Cohort 5: Esophageal or gastroesophageal junction carcinoma (stage II-III),
  • Cohort 6: Gastric adenocarcinoma (stage II-III),
  • Cohort 7: Pancreatic adenocarcinoma that is has been surgically resected or is eligible for surgical resection,
  • Cohort 8: Invasive squamous cell carcinoma of the head and neck (Includes stage I-IVB oral cavity, oropharynx, hypopharynx, larynx, nasopharynx, nasal cavity, and paranasal sinus cancers),
  • Cohort 9: High-risk epithelial ovarian or Fallopian tube carcinoma (Defined as FIGO stage IC-III or stage IA-IB that has high grade or clear cell histology),
  • Cohort 10: High-risk endometrial carcinoma (Defined as 2023 FIGO Stage II-III),
  • Cohort 11: High-risk renal cell carcinoma (Defined as high grade (grade 3-4) stage II, stage III or limited (resectable) stage IV treated with curative intent)

Exploratory Cohort

Exclusion criteria

  • History of allogeneic organ or tissue transplant
  • Index cancer has predominantly neuroendocrine histology
  • History of another primary cancer diagnosed within 3 years of enrollment, with the exception that in situ cancers, non-melanoma skin carcinomas, localized low- or intermediate risk prostate cancers, and stage I papillary thyroid carcinoma, and participants with bilateral/multifocal tumors within the same organ (for example, bilateral breast cancer) are allowed if diagnosed within 3 years of enrollment
  • Known distant metastasis at time of enrollment (with the exception of participants with limited/resectable stage IV cutaneous melanoma or RCC)

Treatment and study plan

Guardant Reveal

Diagnostic Test

Guardant Reveal is a minimal residual disease (MRD) panel for use in recurrence detection of early-stage solid tumors.

Primary outcomes

  1. Distant Recurrence Free Interval (D-RFi)

    Time frame: 3 years

    The primary endpoint, distant recurrence-free interval (D-RFi), will be evaluated for each of the primary study cohorts. D-RFi is defined as the time from the end of primary treatment until the time of diagnosis of a distant recurrence of the Index Cancer. Subjects without a distant recurrence will be censored at the time of last follow-up of their Index Cancer.

Secondary outcomes

  1. Sensitivity

    Time frame: 3 years

    Sensitivity defined as the proportion of participants who develop distant recurrence who have ctDNA detected at or before the time of clinical detection of recurrence.

  2. Positive Predictive Value

    Time frame: 3 years

    Positive predictive value (PPV) defined as the proportion of participants who have ctDNA detected at the landmark or any surveillance timepoint who recur (either distally or locally).

  3. Lead Time

    Time frame: 3 years

    Lead time defined as the interval between ctDNA detection and clinical detection of recurrence.

Other outcomes

  1. Recurrence-free interval (RFi)

    Time frame: 3 years

    Recurrence-free interval (RFi) defined as the time from the end of primary treatment until the appearance/occurrence of any recurrence (distant, regional, and/or local) of the Index Cancer. Subjects without recurrence will be censored at the time of last follow-up of their Index Cancer.

  2. Negative predictive value (NPV)

    Time frame: 3 years

    Negative predictive value (NPV) defined as the proportion of participants who have ctDNA not detected who have no evidence of recurrence.

  3. Association with resolution of indeterminate findings

    Time frame: 3 years

    • The proportion of individuals whose indeterminate finding is ultimately confirmed to be disease recurrence who have ctDNA detected at the initial time the indeterminate finding is identified and
    • The proportion of ctDNA not detected participants whose indeterminate findings is ultimately confirmed to be benign.

  4. Sensitivity for local recurrence

    Time frame: 3 years

    Sensitivity for local recurrence defined as the proportion of participants who have localized recurrence (e.g., in the absence of distant metastasis) who have ctDNA detected at or before the time of clinical detection of a localized recurrence; using landmark and serial timepoints.

  5. Index Cancer-Specific Survival (ICSS)

    Time frame: 3 years

    Index Cancer-Specific Survival (ICSS) defined as the time from the date of diagnosis until the date of death from the subject's Index Cancer. Subjects who are still alive at the end of the study observation period will be censored at the time of last known vital status.

  6. Overall Survival (OS)

    Time frame: 3 years

    Overall Survival (OS) defined as the time from the date of diagnosis until the date of death from any cause. Subjects who are still alive at the end of the study observation period will be censored at the time of last known vital status.

  7. Rate of ctDNA clearance with adjuvant chemotherapy

    Time frame: 3 years

    Rate of ctDNA clearance with adjuvant chemotherapy defined as the proportion of patients who have ctDNA detected at the pre-enrollment timepoint whose ctDNA becomes undetectable at the Landmark timepoint.

  8. Association of ctDNA detection status with pathologic response

    Time frame: 3 years
