Clinical Trial Title Phase II/III study of circulating tumor DNA as a predictive biomarker in adjuvant chemotherapy in stage IIA colon cancer (COBRA)
Trial Status Open to Enrollment
Start Date 03/24/2020
Location Doctors & Locations
Trial Type Cancer - Adult Oncology
Specific Condition Colon cancer
Description This phase II/III trial studies how well circulating tumor deoxyribonucleic acid (ctDNA) testing in the blood works in predicting treatment for patients with stage IIA colon cancer after surgery. ctDNA are circulating tumor cells that are shed by tumors into the blood. Finding ctDNA in the blood means that there is very likely some small amounts of cancer that remain after surgery. However, this cancer, if detected, cannot be found on other tests usually used to find cancer, as it is too small. Testing for ctDNA levels may help identify patients with colon cancer after surgery who do benefit, and those who do not benefit, from receiving chemotherapy.
Eligibility Criteria

Eligibility Criteria

  • Age ≥ 18 years at diagnosis.
  • ECOG Performance Status of 0 or 1.
  • Histologically/pathologically confirmed stage IIA adenocarcinoma of the colon (T3, N0, M0) with at least 12 lymph nodes examined at the time of surgical resection.
  • Appropriate for active surveillance (i.e., no adjuvant chemotherapy) at the discretion of and as documented by the evaluating oncologist based on current practice patterns.
  • The patient must have had an en bloc complete gross resection of tumor (curative resection) as definitive surgical cancer treatment within 14 to 60 days of study randomization. Patients who have had a two-stage surgical procedure to first provide a decompressive colostomy and then, in a later procedure, to have the definitive surgical resection, are eligible.

Ineligibility Criteria

  • Colon cancer histology other than adenocarcinoma (i.e., neuroendocrine carcinoma, sarcoma, lymphoma, squamous cell carcinoma, etc.).
  • Tumor-related bowel perforation.
  • History of prior invasive colon malignancy, regardless of disease-free interval.
