NCT02348203

Brief 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.

Outcome Measures

Primary Outcomes (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.

    Baseline to 12 weeks (End-of-intervention)

Secondary Outcomes (10)

  • 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

    Baseline to 12 weeks (End of Intervention)

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

    Baseline to 14 days post intervention

  • 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

    Baseline to 14 days post intervention

  • Change in Urinary PGE-M Levels

    Baseline to 12 weeks (End-of-intervention)

  • Change in Urinary LTE (4) Levels

    Baseline to 12 weeks (End-of-intervention)

  • +5 more secondary outcomes

  • Fertile subjects must use adequate contraception (abstinence, barrier methods, or birth control pills) prior to study entry and for the duration of study participation; women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
  • Participants may have a history of indeterminate pulmonary nodule(s) by chest imaging if nodule follow-up has been completed or the study procedures would not interfere with nodule follow-up
