Clinical Trial Summary

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.

Description:

PRIMARY OBJECTIVES:

I. 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:

I. 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.

V. 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	Baseline to 12 weeks (End-of-intervention)
Secondary	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.	Baseline to 12 weeks (End of Intervention)
Secondary	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.	Baseline to 14 days post intervention
Secondary	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.	Baseline to 14 days post intervention
Secondary	Change in Urinary PGE-M Levels		Baseline to 12 weeks (End-of-intervention)
Secondary	Change in Urinary LTE (4) Levels		Baseline to 12 weeks (End-of-intervention)
Secondary	Number of Participants Experiencing Possibly/Probably/Definitely-related Adverse Events		Up to 2 weeks post-treatment
Secondary	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.	Baseline to 12 weeks (End-of-intervention)
Secondary	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.	Baseline to 12 weeks (End-of-intervention)
Secondary	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	Baseline to 12 weeks (End-of-intervention)
Secondary	Impact of ASA and Zileuton on Karyometric Analysis of Buccal Cells		Up to week 12
