  • Adverse Events (assessed according to the Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0)
Being tested
Metformin and Fluorouracil

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Disease Control Rate according to RECIST 1.1

    Measured: From randomization of the first subject until the database cut-off approximately 12 months later (01Nov2012 up to 01Nov2015). Tumor assessed at 8 week intervals

Secondary outcomes (3)
  1. Progression-free Survival

    defined as time from randomization to death from any cause, or even radiological detection/or clinical of disease progression, increased CEA will not be considered isolated progression.

    Measured: From randomization of the first subject until the database cut-off approximately 12 months later (01Nov2012 up to 01Nov2015). Tumor assessed at 4 week intervals.

  2. Overall Survival

    defined as time from first dose of treatment until death, with date of last visit being considered censorship

    Measured: From randomization of the first subject until the database cut-off approximately 12 months later (01Nov2012 up to 01Nov2015). Tumor assessed at 4 week intervals

  3. Adverse Events

    Measured: From randomization of the first subject until the database cut-off approximately 12 months later (01Nov2012 up to 01Nov2015). Tumor assessed at 4 week intervals.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Metformin and Fluorouracil in people with Metastatic Colorectal Cancer, run by Instituto do Cancer do Estado de São Paulo at 1 site in Brazil.

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 13 inclusion and 15 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 8 Apr 2015. 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 Brazil. 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?

Disease Control Rate according to RECIST 1.1 (time frame: From randomization of the first subject until the database cut-off approximately 12 months later (01Nov2012 up to 01Nov2015). Tumor assessed at 8 week intervals). 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 8 Apr 2015.
