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. It is not yet known whether chemotherapy is more effective than observation in patients who have had surgery to remove colorectal cancer. Read more about this study

About this study

Official title: A UKCCCR Study of Adjuvant Chemotherapy for Colorectal Cancer

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. It is not yet known whether chemotherapy is more effective than observation in patients who have had surgery to remove colorectal cancer.

PURPOSE: This randomized phase III trial is studying leucovorin and fluorouracil to see how well they work compared to observation in treating patients with colorectal cancer that has been surgically removed.

Read the detailed description

OBJECTIVES:

  • Compare all-cause mortality in patients with resected colorectal cancer treated with adjuvant chemotherapy with L-leucovorin and fluorouracil vs observation.
  • Compare the recurrence rates in patients treated with this regimen vs observation.
  • Compare the effectiveness of a monthly 5-day schedule vs a once weekly schedule of L-leucovorin and fluorouracil in this patient population.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are randomized to receive adjuvant chemotherapy (arm I) or undergo observation only (arm II).

  • Arm I: Within 12 weeks of surgery, patients receive L-leucovorin IV followed by fluorouracil IV on days 1-5 every 4 weeks for 6 courses. Alternatively, patients may receive L-leucovorin IV followed by fluorouracil IV on day 1 weekly for 30 weeks.
  • Arm II: Patients undergo observation. Patients are followed annually.

PROJECTED ACCRUAL: A total of 2,500 patients (1,250 per arm) will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing L-leucovorin, fluorouracil and adjuvant therapy in people with Colorectal Cancer, run by Institute of Cancer Research, United Kingdom at 1 site in United Kingdom.

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 Dec 2013. 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 Kingdom. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

All-cause mortality. 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 NCT00005586, 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 18 Dec 2013.
