Colorectal CancerPhase 2NCT00165568
Using Positron Emission Tomography to Evaluate the Effects of Bevacizumab on Intra-tumoral Pharmacokinetics of 5-fluorouracil in Metastatic Colorectal Cancer
A Phase 2 study testing Bevacizumab in people with Colorectal Cancer and Neoplasm Metastasis, run by Dana-Farber Cancer Institute at 2 sites in United States.
Trial summary
The purpose of this study is to investigate whether bevacizumab helps 5-Fluorouracil (5-FU) be delivered to the tumor more efficiently. Bevacizumab has been shown to inhibit the formation of new blood vessels in tumors and works best in combination with drugs that require blood vessels for transportation. Read more about this study

- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Metastatic colorectal cancer subjects
- Subjects must have at least one non-radiated FDG-glucose avid (as demonstrated by an FDG-glucose PET scan) liver metastasis of at least 2 cm in size.
- Subjects must have never received chemotherapy for metastatic disease; subjects may have received adjuvant chemotherapy for presumed early stage disease if it was completed at least 12 months prior to study entry date
- All subjects must have already consented to an on-label use of a BV and fluorouracil containing first-line chemotherapy regimen (either with irinotecan or oxaliplatin) and must be a candidate for such a therapy as defined by the enrolling investigator and the community standard of care. As such a chemotherapy regimen requires an infusion port, this port should be placed at least two weeks prior to the subject's first dose of bevacizumab.

About this study
The purpose of this study is to investigate whether bevacizumab helps 5-Fluorouracil (5-FU) be delivered to the tumor more efficiently. Bevacizumab has been shown to inhibit the formation of new blood vessels in tumors and works best in combination with drugs that require blood vessels for transportation. Based on other experiments, bevacizumab may work by improving the transportation of other drugs to the tumor.
Read the detailed description
- This is not a treatment study. A treatment regimen has already been decided upon by the patient and doctor.
- At the screening visit for this trial the following will be performed: a medical history, physical examination, CT scan to measure the amount and size of the tumor(s), and a PET scan using glucose that has been attached to a small amount of radioactivity to determine how well the tumor takes up glucose.
- Patients will then be randomized into one of 2 treatment groups. Group 1 will receive both 5-FU and bevacizumab on the first day of chemotherapy. Group 2 will receive just 5-FU on the first day of chemotherapy.
- Patients will undergo a PET scan that uses water that has been attached to a small amount of radioactivity to measure how well the tumor takes up water prior to the 5-FU adminstration.
- After patients receive 5-Fu they will undergo a PET scan during which a small amount of 5-FU has been attached to a small amount of radioactivity to measure how well the tumor takes up 5-FU.

What is being measured
The primary outcome is the main question the study is designed to answer.
To compare the percent change in tumor radioactivity uptake and retention after radiolabeled fluorouracil administration in subjects who receive bevacizumab versus those who do not receive bevacizumab.
Secondary outcomes (2)
To compare the percent change in tumor flow induced by bevacizumab and fluorouracil
to evaluate the relationship between initial change in tumor radioactivity uptake and retention.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Bevacizumab in people with Colorectal Cancer and Neoplasm Metastasis, run by Dana-Farber Cancer Institute at 2 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?
The sponsor lists 10 inclusion and 2 exclusion criteria. 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 2 Nov 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 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 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?
To compare the percent change in tumor radioactivity uptake and retention after radiolabeled fluorouracil administration in subjects who receive bevacizumab versus those who do not receive bevacizumab.. 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 2 Nov 2009.
