About this study
Official title: A Phase II Trial of Neoadjuvant Capecitabine, Oxaliplatin, and Bevacizumab for Resectable Colorectal Metastases in the Liver
RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, 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 bevacizumab, 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. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving capecitabine and oxaliplatin together with bevacizumab before and after surgery may be an effective treatment for liver metastases.
PURPOSE: This phase II trial is studying how well giving capecitabine and oxaliplatin together with bevacizumab works in treating patients who are undergoing surgery for liver metastases due to colorectal cancer.
Read the detailed description
OBJECTIVES:
- Determine the proportion of patients with resectable hepatic metastases secondary to colorectal cancer who undergo surgical resection and achieve a R0 resection after treatment with neoadjuvant capecitabine, oxaliplatin, and bevacizumab.
- Determine the probability of non-progression (i.e., stable disease or response [complete and partial, confirmed and unconfirmed]) in patients treated with this regimen.
- Compare the proportion of patients treated with this regimen who undergo surgical resection and those who achieve a R0 resection with that described in the literature.
- Determine overall survival and disease-free survival of patients treated with this regimen.
- Determine response by positron emission tomography in patients treated with this regimen.
- Correlate clinical outcome with expression of biomarkers (e.g., thymidylate synthase, dihydropyrimidine dehydrogenase, thymidine phosphorylase, excision repair cross complementing 1, and hTERT) and telomere length in patients treated with this regimen.
OUTLINE: This is a multicenter study.
- Neoadjuvant therapy: Patients receive bevacizumab* IV over 30-90 minutes and oxaliplatin IV over 2 hours on day 1 and oral capecitabine twice daily on days 1-14. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
NOTE: *Bevacizumab is administered during courses 1-3 of neoadjuvant therapy.
- Surgery: Approximately 3-4 weeks after completion of neoadjuvant therapy, patients are evaluated. Patients with unresectable disease are removed from the study. Patients with resectable disease undergo surgical resection of liver metastases within 4-6 weeks after completion of neoadjuvant therapy.
- Adjuvant therapy: Beginning at least 28 days after surgical resection, patients with at least stable disease after completion of neoadjuvant therapy receive 4 courses of adjuvant bevacizumab**, oxaliplatin, and capecitabine as in neoadjuvant therapy.
NOTE: **Bevacizumab is administered during courses 1-4 of adjuvant therapy.
After completion of study treatment, patients are followed every 4 months until disease progression and then every 6 months for up to 3 years from study entry.
PROJECTED ACCRUAL: Approximately 35-65 patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing bevacizumab, capecitabine and oxaliplatin in people with Colorectal Cancer and Metastatic Cancer, run by SWOG Cancer Research Network at 46 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: withdrawn, as of the sponsor's last update on 3 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 46 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?
The study was withdrawn before enrolling participants, so there are no results.
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?
Proportion of patients with R0 resection after treatment (time frame: 16-18 weeks from registration). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00118105, which also lists 1 linked publication.
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 3 Jan 2013.
