ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation

ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation

Recruiting
18 years and older
All
Phase N/A

Powered by AI

Overview

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.

Eligibility

Inclusion Criteria:

  • Age \> 18 years old AND
  • Initial treatment is given with curative/radical intent AND
  • Are planning to undergo regular follow-up and monitoring for cancer recurrence per standard of care at the enrolling site AND

  • Are willing to have de-identified clinical data shared with investigators at regular intervals as outlined in the study protocol and informed consent AND
  • Are willing to provide blood samples at enrollment and at subsequent clinical visits coinciding with standard of care follow-up, for up to 5 years as outlined in the study protocol and informed consent AND
  • Have at least one Landmark blood sample

Have a histologically confirmed Index Cancer that qualifies for inclusion, defined as:

  • 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

  • Cohort 12: Pathologically confirmed adenocarcinoma of the rectum (located up to 15 cm from the anal verge) that is undergoing or underwent a preoperative chemotherapy- or immunotherapy- containing regimen

Exclusion Criteria:

  • 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)

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
