Antibody therapy aims to keep colon cancer from returning
NCT ID NCT00002968
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase III trial tested whether adding a monoclonal antibody called edrecolomab to surgery helps people with stage II colon cancer live longer or stay cancer-free longer. About 2,100 participants were randomly assigned to receive either the antibody or no additional treatment after surgery. The study tracked survival and how long it took for the cancer to come back.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- edrecolomab (monoclonal antibody 17-1A)
- What this could lead to
- If successful, this could provide an additional treatment option to reduce the risk of cancer returning after surgery for stage II colon cancer.
- What could go wrong
- This trial is completed but results may not show a clear benefit over surgery alone. Monoclonal antibodies can cause infusion reactions or allergic responses.

Inclusion Criteria: * Pathologic documentation of adenocarcinoma of the colon with or without penetration of the serosa with no lymph node metastases (Stage II pT3N0 or pT4bNO lesions, excluding pT4aN0; Modified Astler-Coller Stage B2); there can be no distant metastases or penetration of adjacent organs or structures; proximal, distal, and radial margins must be free of tumor Important note: A tumor nodule \> 3 mm in diameter in the perirectal or pericolonic adipose tissue without histologic evidence of residual node in the nodule is classified as regional/pericolonic node metastasis; however, a tumor nodule =\< 3 mm in diameter is classified in the T category as discontinuous extension (i.e., pT3); multiple metastatic foci seen microscopically only in the pericolonic fat should be considered as metastasis in a single lymph node for classification; although six or more nodes evaluated from the specimen is optimal, a minimum of three nodes (periodic or mesenteric) for evaluation is required for inclusion in the study * Complete, en bloc resection of all the primary tumor, performed as an open procedure, and not laparoscopically or laparoscopically assisted * No evidence of perforation or clinical obstruction of the bowel * The gross distal margin of the primary tumor must lie above the peritoneal reflection (i.e., it must be a colon, not a rectal cancer) * No previous radiation or chemotherapy for this malignancy * CALGB Performance status 0-1 * No concurrent treatment with systemic steroids is allowed; patients receiving replacement steroids for adrenal insufficiency are eligible; patients receiving inhaled steroids in daily doses of 500mg or less and patients being treated with topical steroids are eligible * No prior exposure to murine antibodies (e.g., diagnostic tests like the "oncoscint scan") * No uncontrolled or severe cardiovascular disease * No history of pancreatitis * Non-pregnant and non-lactating; patients of child-bearing potential should agree to use an effective method of birth control * No previous or concurrent malignancy is allowed, except inactive non-melanoma skin cancer, in situ carcinoma of the cervix, or other cancer if the patient has been disease-free for \>= 5 years; patients with more than one synchronous primary colon tumor are eligible; for the purpose of this protocol, staging classification will be based on the stage of the more advanced primary tumor * Granulocytes \> 1,800/μl * Platelet count \> 100,000/μl * BUN \< 1.5 x normal * Creatinine \< 1.5 x normal * Bilirubin \< 1.5 x normal
