About this study

Official title: Clinical Study of the Effect of Combined Treatment of Aspirin and Zileuton on Biomarkers of Tobacco-Related Carcinogenesis in Current Smokers

This randomized phase II trial studies the effects of aspirin and zileuton on genes related to tobacco use in current smokers. Aspirin and zileuton may interfere with genes related to tobacco use and may be useful in preventing lung cancer in current smokers.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To analyze the impact of combined treatment of acetylsalicylic acid (ASA) (aspirin) and zileuton on smoking-related gene expression signature in the nasal epithelium in current smokers and to analyze any difference between the ASA and zileuton intervention and placebo control.

SECONDARY OBJECTIVES:

  1. To assess the impact of ASA and zileuton on three lung cancer gene signatures (an 80-gene bronchial signature, a phosphatidylinositol 3-kinase [PI3K] pathway gene signature and a nasal diagnostic gene signature) and to compare this to placebo control.

II. To determine whether the change in the smoking-related gene expression signature and the three lung cancer gene signatures of nasal epithelium persists 10-14 days off agent intervention.

III. To measure urinary prostaglandin E metabolite (PGE-M) and leukotriene E(4) (LTE[4]) levels in current smokers after ASA and zileuton.

IV. To assess the safety in current smokers of 12 week exposure to ASA and zileuton.

  1. To evaluate a gender effect in the modulatory effects of ASA and zileuton on smoking related-gene expression signature.

VI. To explore the effect of ASA and zileuton on the metabolomics profile of the arachidonic acid pathway.

VII. To explore, in a discovery-driven fashion, the effect of ASA and zileuton on whole-genome gene expression.

VIII. To analyze the impact of ASA and zileuton on karyometric analysis of buccal cells.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive aspirin orally (PO) once daily (QD) and zileuton PO twice daily (BID) for 12 weeks in the absence of unacceptable toxicity.

ARM II: Patients receive aspirin placebo PO QD and zileuton placebo PO BID for 12 weeks.

After completion of study treatment, patients are followed up for 2 weeks.

What is being measured

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

  1. Changes in a Smoking-related Gene Expression Signature Score in the Nasal Epithelium of Current Smokers

    Change in a nasal smoking-related gene expression signature score derived from prior research was compared between the two study arms. Prior research showed that a higher score was observed in never smokers compared to current smokers. An increased score implicated a more favorable intervention effect. There is no minimum or maximum score.

    Measured: Baseline to 12 weeks (End-of-intervention)

Secondary outcomes (10)
  1. Changes in Three Lung Cancer Gene Signatures (an 80-gene Bronchial Signature, a PI3K Pathway Gene Signature and a Nasal Diagnostic Gene Signature) in the Nasal Epithelium of Current Smokers

    Change in three lung cancer gene signatures (an 80-gene bronchial signature, a PI3K pathway gene signature and a nasal diagnostic gene signature) derived from prior research was compared between the two study arms. A decreased signature score implicated a more favorable intervention effect. There is no minimum or maximum score.

    Measured: Baseline to 12 weeks (End of Intervention)

  2. Changes in a Smoking-related Gene Expression Signature Score in the Nasal Epithelium of Current Smokers 10-14 Days Post Intervention

    Change (from baseline to 10-14 days off intervention) in a nasal smoking-related gene expression signature score derived from prior research was compared between the two study arms. Prior research showed that a higher score was observed in never smokers compared to current smokers. An increased score implicated a more favorable intervention effect. There is no minimum or maximum score.

    Measured: Baseline to 14 days post intervention

  3. Changes in Three Lung Cancer Gene Signatures (an 80-gene Bronchial Signature, a PI3K Pathway Gene Signature and a Nasal Diagnostic Gene Signature) in the Nasal Epithelium of Current Smokers 10-14 Days Post Intervention

    Change (from baseline to 10-14 days off intervention) in three lung cancer gene signatures (an 80-gene bronchial signature, a PI3K pathway gene signature and a nasal diagnostic gene signature) derived from prior research was compared between the two study arms. A decreased signature score implicated a more favorable intervention effect. There is no minimum or maximum score.

    Measured: Baseline to 14 days post intervention

  4. Change in Urinary PGE-M Levels

    Measured: Baseline to 12 weeks (End-of-intervention)

  5. Change in Urinary LTE (4) Levels

    Measured: Baseline to 12 weeks (End-of-intervention)

  6. Number of Participants Experiencing Possibly/Probably/Definitely-related Adverse Events

    Measured: Up to 2 weeks post-treatment

  7. Gender Effect on Smoking-related Gene Expression Signature

    Change in a nasal smoking-related gene expression signature score derived from prior research was analyzed by gender. Prior research showed that a higher score was observed in never smokers compared to current smokers. An increased score implicated a more favorable intervention effect. There is no minimum or maximum score.

    Measured: Baseline to 12 weeks (End-of-intervention)

  8. Changes in the Metabolomics Profile of the Arachidonic Acid Pathway

    Two sample t tests will be performed to evaluate whether or not there are significant differences in changes in oxylipin metabolome between the treatment and placebo groups. In addition, system biology methods will also be used to analyze the oxylipin metabolome data.

    Measured: Baseline to 12 weeks (End-of-intervention)

  9. Number of Genes Differentially Expressed After Aspirin and Zileuton Intervention Compared to Placebo

    Number of genes differentially expressed after aspirin and zileuton intervention compared to placebo using whole-genome gene expression data

    Measured: Baseline to 12 weeks (End-of-intervention)

  10. Impact of ASA and Zileuton on Karyometric Analysis of Buccal Cells

    Measured: Up to week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Aspirin, Laboratory Biomarker Analysis and Zileuton in people with Tobacco Use Disorder, run by National Cancer Institute (NCI) 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 13 inclusion and 21 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 Jun 2022. 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. 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 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?

Yes. Results are posted in the registry (first posted 23 Mar 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Changes in a Smoking-related Gene Expression Signature Score in the Nasal Epithelium of Current Smokers (time frame: Baseline to 12 weeks (End-of-intervention)). 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 Jun 2022.
