About this study

Official title: A Double Blind Placebo-Controlled Trial of Eflornithine and Sulindac to Prevent Recurrence of High Risk Adenomas and Second Primary Colorectal Cancers in Patients With Stage 0-III Colon or Rectal Cancer, Phase III - Preventing Adenomas of the Colon With Eflornithine and Sulindac (PACES)

The investigators hypothesize that the combination of eflornithine and sulindac will be effective in reducing a three-year event rate of adenomas and second primary colorectal cancers in patients previously treated for Stages 0 through III colon or rectal cancer.

Read the detailed description

The purpose of this study is to assess whether the combination of eflornithine 500 mg and sulindac 150 mg (compared to corresponding placebos) has efficacy against colorectal lesions with respect to high-grade dysplasia, adenomas with villous features, adenomas 1 cm or greater, multiple adenomas, any adenomas >/= 0.3 cm, total advanced colorectal events, or total colorectal events.

What is being measured

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

  1. Event rate, defined as rate of high-risk adenoma or second primary colorectal cancer (CRC)

    High risk adenoma is defined as either advanced adenoma (villous or tubulovillous histology, size >= 1 cm, or high grade dysplasia) or multiple adenomas (3 or more each > 0.3 cm). The primary analysis of the 3-year event rate will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A two-arm binomial design without continuity correction will be used.

    Measured: 3 years after registration

Secondary outcomes (15)

  1. Total advanced colorectal event rate, defined as the number of patients with at least one high risk adenoma, second primary CRC, CRC recurrence, or metastasis

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  2. Colon cancer recurrence

    Statistical assessments of association between the biomarker and the recurrence endpoints will be performed after converting the biomarker scores to ranks, which will facilitate detection of monotonic relationship(s).

    Measured: Up to 8 years

  3. High-grade dysplasia

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  4. Adenomas with villous features, defined as villous histology (villous and tubulovillous adenomas)

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  5. Adenomas >= 1 cm

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  6. Multiple adenomas, defined as 3 or more adenomas all measuring > 0.3 cm

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  7. The number of patients with development of any adenoma > 0.3 cm

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  8. Total colorectal event rate, defined as the number of patients with at least one colorectal event (advanced colorectal event or adenoma > 0.3 cm)

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: Up to 8 years

  9. Time to first clinically apparent high-risk adenoma or second primary CRC

    The analysis will be performed using logistic regression, testing the main effect of treatment and adjusting for the baseline stratification factor. A time-to-event analysis will be conducted if there is no evidence of differential rates of on-study colonoscopies. To evaluate whether intervention effects are enduring, an analysis of post-treatment follow-up, examining colorectal event rates through year 8 will be performed.

    Measured: From date of registration to date at which high-risk adenoma or second primary CRC is detected, up to 8 years

  10. Toxicity

    Qualitative and quantitative assessment of toxicity, collected as CTCAE adverse events. Particular adverse events of interest include thrombotic cardiovascular and ototoxic events at or above a specified grade (e.g., Grade III or worse). All patients who receive any treatment will be included in the analysis of adverse events.

    Measured: Up to 3 years

  11. Baseline statin use

    The analysis of the interaction of statin use and the 3-year event rate will be performed using logistic regression.

    Measured: Up to 3 years

  12. Baseline meat consumption

    The analysis of the interaction of meat consumption and the 3-year event rate will be performed using logistic regression.

    Measured: Up to 3 years

  13. PK analysis

    SNPs with minor allele frequencies greater than 0.20 will be selected for SNP genotyping. The smallest set of SNPs that tag the common variation (frequency > 0.20) in all of the representative ethnic groups will be used. The genotype data, treatment characteristics and endpoints of interest will be analyzed using the pharmacogenetic-environment interaction approach described by Wacholder and colleagues.

    Measured: Up to 3 years

  14. Biomarker identification based on Integrated Comprehensive Droplet Digital Detection technology

    The nature of the relationship between biomarker values identified by Integrated Comprehensive Droplet Digital Detection technology and the aggregate primary endpoint (high-risk adenoma or second primary CRC) will be assessed. Statistical assessments of association between the biomarker and the recurrence endpoints will be performed after converting the biomarker scores to ranks, which will facilitate detection of monotonic relationship(s).

    Measured: Up to 3 years (though the timing of this isn't clear to me)

  15. Cancer type (colorectal vs rectal)

    The analysis of the interaction of cancer type (colorectal vs rectal) and the 3-year event rate will be performed using logistic regression.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Eflornithine plus sulindac in people with Colorectal Neoplasms, run by SWOG Cancer Research Network at 989 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 13 inclusion and 12 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: under way, not looking for participants, as of the sponsor's last update on 23 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 989 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

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?

Event rate, defined as rate of high-risk adenoma or second primary colorectal cancer (CRC) (time frame: 3 years after registration). 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 NCT01349881.

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 23 Oct 2026.
