About this study
Official title: Evaluating BRAF Mutations as Predictors of Efficacy in Cetuximab-Treated Colorectal Cancer Patients: A Retrospective Study of Tissues From CALGB / SWOG
RATIONALE: Studying samples of tissue in the laboratory from patients who received cetuximab may help doctors understand and predict how well patients will respond to treatment.
PURPOSE: This research study is studying biomarkers in predicting response to cetuximab in patients with advanced colorectal cancer.
Read the detailed description
OBJECTIVES:
Primary
- To determine, among patients with advanced CRC, whether the effect of treatment (cetuximab vs bevacizumab) on progression-free survival (PFS) depends on tumor BRAF V600E mutational status.
Secondary
- To study the relationships between tumor BRAF V600E mutational status, OS, and tumor response.
OUTLINE: This is a multicenter study.
Previously collected formalin-fixed and paraffin-embedded baseline tumor samples are analyzed for BRAF V600E mutation. Mutation status is correlated with clinical response and outcome data from patients enrolled on CALGB-C80405.
- Conditions
- Colorectal Cancer
- Being tested
- mutation analysis, laboratory biomarker analysis
- Keywords
- recurrent colon cancer, stage IIIA colon cancer, stage IIIB colon cancer, stage IIIC colon cancer, stage IVA colon cancer, stage IVB colon cancer, recurrent rectal cancer, stage III rectal cancer, stage IV rectal cancer

Questions about this trial
What is this clinical trial studying?
An observational study of Colorectal Cancer, run by Alliance for Clinical Trials in Oncology.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival as measured by RECIST (time frame: Up to 36 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2020.
