S0713: Oxaliplatin, Capecitabine, Cetuximab, and RT Followed By Surgery in Pts W/Stage II or III Rectal Cancer
A Phase 2 study testing cetuximab, capecitabine and oxaliplatin in people with Colorectal Cancer, run by SWOG Cancer Research Network at 130 sites in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Read more about this study

About this study
Official title: A Phase II Study of Oxaliplatin, Capecitabine, Cetuximab and Radiation in Pre-Operative Therapy of Rectal Cancer
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
PURPOSE: This phase II trial is studying the side effects and how well giving oxaliplatin, capecitabine, and cetuximab together with radiation therapy followed by surgery works in treating patients with stage II or stage III rectal cancer.
Read the detailed description
OBJECTIVES:
- To assess the pathologic complete response rate for the combination of oxaliplatin, capecitabine, and cetuximab alone and concurrently with external beam radiotherapy for patients with adenocarcinoma of the rectum, stages II and III with wild-type K-ras.
- To estimate the 3-year disease-free survival probability in this patient population when treated with this regimen.
- To assess the frequency and severity of toxicities associated with this regimen in these patients.
- To explore, preliminarily, the association between expression levels of genes involved in the DNA repair, EGFR (epidermal growth factor receptor), angiogenesis, and 5-FU pathway (i.e., k-ras, TS [Thymidylate Synthase], ERCC-1 [excision repair cross complementing-1), TP [Thymidine phosphorylase], DPD [Dihydropyrimidine dehydrogenase], EGFR, VEGF [vascular endothelial growth factor], and IL-8 [interleukin-8]) and pathologic complete response. (Due to advances in methodology, the translational medicine objectives are being reconsidered. Therefore, results for this objective are not reported)
- To explore, preliminarily, the intratumoral gene expression levels of these genes after completion of study treatment.(Due to advances in methodology, the translational medicine objectives are being reconsidered. Therefore, results for this objective are not reported)
- To obtain, preliminarily, data on genomic polymorphisms of these genes for correlation with clinical outcome and toxicity. (Due to advances in methodology, the translational medicine objectives are being reconsidered. Therefore, results for this objective are not reported)
OUTLINE: This is a multicenter study.
- Neoadjuvant therapy (course 1): Patients receive oxaliplatin IV over 2 hours once a week for 5 weeks, oral capecitabine twice daily 5 days a week for 5 weeks, and cetuximab IV over 1-2 hours once a week for 5 weeks.
- Neoadjuvant therapy with concurrent radiotherapy (course 2): Beginning two weeks later, patients receive oxaliplatin IV over 2 hours once a week in weeks 1, 2, 4, and 5. Patients also receive capecitabine and cetuximab as in course 1. Patients also undergo external beam radiotherapy 5 days a week for 5 weeks beginning in week 1.
Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo surgery 3-8 weeks after completion of chemoradiotherapy.
Blood samples are collected for germline polymorphism testing and tissue samples are collected and assessed for gene expression analysis.
After completion of study treatment, patients are followed every 6 months for 4 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pathologic Complete Response Rate
Pathologic response is evaluated after the patient has had surgery, and is based on local pathology review of the resected surgical specimen, according to the following: a) Pathologic complete response (pCR): on review of the resected rectal specimen and accompanying lymph nodes, no cancer is recognized by the pathologist; b) Microscopic cancer: gross tumor is not seen by the pathologist but tumor remains in the microscopic analysis of any part of the entire specimen; c) no response: gross cancer is found on pathologic examination of the resected rectal cancer and draining lymph nodes.
Measured: 15-20 weeks from registration
Secondary outcomes (2)
3-year Disease-free Survival
From date of registration to date of first documentation of progression or symptomatic deterioration, or death due to any cause. Patients last known to be alive and progression free are censored at date of last contact.
Measured: 3 years
Number of Patients With Grade 3 Through Grade 5 Adverse Events That Are Related to This Regimen.
Only adverse events that are possibly, probably or definitely related to study regimen are reported.
Measured: Up to 4 years

Primary outcome
Pathologic Complete Response Rate
Time frame: 15-20 weeks from registration
Pathologic response is evaluated after the patient has had surgery, and is based on local pathology review of the resected surgical specimen, according to the following: a) Pathologic complete response (pCR): on review of the resected rectal specimen and accompanying lymph nodes, no cancer is recognized by the pathologist; b) Microscopic cancer: gross tumor is not seen by the pathologist but tumor remains in the microscopic analysis of any part of the entire specimen; c) no response: gross cancer is found on pathologic examination of the resected rectal cancer and draining lymph nodes.
2 secondary outcomes
3-year Disease-free Survival

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing cetuximab, capecitabine and oxaliplatin in people with Colorectal Cancer, run by SWOG Cancer Research Network at 130 sites in United States.
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 18 May 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 130 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Feb 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Pathologic Complete Response Rate (time frame: 15-20 weeks from registration). 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 18 May 2018.
