Brief Summary:
This randomized phase II trial studies acetylsalicylic acid compared to placebo in treating high-risk patients with subsolid lung nodules. A nodule is a growth or lump that may be malignant (cancer) or benign (not cancer). Chemoprevention is the use of drugs to keep cancer from forming or coming back. The use of acetylsalicylic acid may keep cancer from forming in patients with subsolid lung nodules.

Condition or disease Intervention/treatment Phase
Current Smoker Former Smoker Multiple Pulmonary Nodules Tobacco Use Disorder Drug: Aspirin Other: Laboratory Biomarker Analysis Other: Placebo Phase 2

Detailed Description:


I. The evaluation of the effect of aspirin (acetylsalicylic acid) as a chemopreventive agent for lung cancer.


I. The modulation of biological markers after treatment and the correlation of these findings with modification of lung nodules diameters.

II. The per-lesion analysis including the evaluation of lung nodule density before and after treatment, the number and size of non target lesions including solid nodules and evaluation of response according to modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive acetylsalicylic acid orally (PO) once daily (QD) for 12 months.

ARM II: Patients receive placebo PO QD for 12 months.

After completion of study treatment, patients are followed up for 1 month.

Primary Outcome Measures :
  1. Change in the Sum of Longest Diameters of Baseline Target Nodules (Person-specific Analysis) [ Time Frame: Twelve-month treatment ]
    Difference (12 month-baseline) in the sum of longest diameters of baseline target nodules.

Secondary Outcome Measures :
  1. Change in the Sum of Baseline Target Nodules Diameters (Per Nodules Analysis) [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) in the sum of baseline target nodules diameters

  2. Change in Lesion Volume [ Time Frame: Baseline to 1 year ]
    Difference (12 month-baseline) in lesion volume

  3. Change in Lesion Density [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) in lesion density

  4. Modulation of Thromboxane B2 [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) in biomarker concentration

  5. Modulation of Prostaglandin E Metabolites (Normalized to Urinary Creatinine Concentration) [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) in biomarker concentration

  6. Modulation of Leukotriene E4 (Normalized to Urinary Creatinine Concentration) [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) in biomarker concentration

  7. Modulation of High Sensitive CRP [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) in biomarker concentration

  8. Modulation of miRNA Prediction Risk Score [ Time Frame: Baseline up to 1 year ]
    Difference (12 month-baseline) of the score on a scale (scale from -20 to +30 which measure the risk of lung cancer. Higher values indicate higher risk. A value<0 is considered negative, a value ≥0 positive for lung cancer).
