Intermittent or Continuous Acetylsalicylic Acid and Gene Expression in the Nasal Tissue of Current Smokers

Completed · Phase 2 · Has a placebo group

Conditions studied: Lung Carcinoma, Tobacco Use Disorder

In brief

This randomized phase II trial studies the safety and effects of acetylsalicylic acid (aspirin) taken continuously or intermittently on gene expression in the nasal tissue of current smokers. Smokers are at increased risk of developing lung cancer. Acetylsalicylic acid may be useful in preventing lung cancer.

• Pregnant or lactating women; breastfeeding should be discontinued if the mother is treated with aspirin; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
• Participants may not be receiving any other investigational agents
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
