Combination Chemotherapy in Treating Patients With Metastatic Colorectal Cancer
A Phase 2 study testing O6-benzylguanine and carmustine in people with Colorectal Cancer, run by Case Comprehensive Cancer Center at 1 site in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have metastatic colorectal cancer. Read more about this study

About this study
Official title: Phase II Trial of O6Benzylguanine and BCNU in Patients With Colon and Rectal Carcinoma
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have metastatic colorectal cancer.
Read the detailed description
OBJECTIVES:
- Determine the response rate of patients with metastatic colorectal carcinoma treated with O6-benzylguanine and carmustine.
- Evaluate tumor tissue biochemical and immunohistochemical predictors of response in patients treated with this regimen.
- Correlate carcinoembryonic antigen levels in the peripheral blood with response in patients treated with this regimen.
OUTLINE: This is a multicenter study.
Patients receive O6-benzylguanine (BG) IV over 1 hour and carmustine IV over 1 hour (beginning 1 hour after completion of BG infusion) on day 1. Treatment continues every 6 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months.
PROJECTED ACCRUAL: A total of 19-36 patients will be accrued for this study within 1.7-3 years.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing O6-benzylguanine and carmustine in people with Colorectal Cancer, run by Case Comprehensive Cancer Center at 1 site 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 10 Jun 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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?
Determine the response rate of patients with metastatic colorectal carcinoma treated with O6-benzylguanine and carmustine. (time frame: Treatment continues every 6 weeks in the absence of disease progression or unacceptable toxicity.). 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 10 Jun 2010.
